    configure.ac: Make it possible to build on Android Termux

    The recent Termux's clang predefines `__ANDROID_API__` as a fixed number
    24. However, when it is lower to the current device version, some
    functions that "configure" determines available are not declared
    correctly in the header files.

    This change forces to overwrite the predefined `__ANDROID_API__` macro
    with the current device version.

    Fix class of method in Method#inspect for singleton classes of classes

    Previously, due to a change to fix bug 15608, Method#inspect output
    changed for class methods:

    Ruby 2.7
    "#<Method: String.prepend(*)>"

    Before change:
    "#<Method: #<Class:Object>(Module)#prepend(*)>"

    This is wrong because the Method object was created from String and
    not Object. This is because the fix for bug 15608 assumed it was
    being called on the singleton class of a instance, and would skip
    the first singleton class until it got to the class itself.  For
    class methods, this results in always using the superclass. Fix
    behavior to not skip until the superclass if the singleton class
    is the singleton class of a module or class.

    After change:
    "#<Method: #<Class:Object>(Module)#prepend(*)>"

    Fixes [Bug #17428]

    rb_cData: no longer exists

    Commit 8918a9cf6c65409ae1ffcdea324a1b97c6e5bb70 introduced macro
    `#define rb_cData rb_cData()`.  This deleting `VALUE rb_cData;`
    declaration was then macro-expanded into `VALUE rb_cData();`.  This
    worked by accident because the expanded expression happen to be a K&R
    style function declaration.

    This is rather complicated and I guess unintended.  Just delete the line
    to keep things simple straight forward.

    Data: delete

    Has been deprecated since 684bdf6171b76f5bc5e4f05926a5ab01ec2b4fd5.

    Matz says in [ruby-core:83954] that Data should be an alias of Object.
    Because rb_cData has not been deprecated, let us deprecate the constant
    to make it a C-level synonym of rb_cObject.

    [json] Avoid method redefinition

    Introduce Ractor::IsolationError

    Ractor has several restrictions to keep each ractor being isolated
    and some operation such as `CONST="foo"` in non-main ractor raises
    an exception. This kind of operation raises an error but there is
    confusion (some code raises RuntimeError and some code raises
    NameError).

    To make clear we introduce Ractor::IsolationError which is raised
    when the isolation between ractors is violated.

    Mark active_units

    to avoid SEGV on mjit_recompile and compact_all_jit_code.

    For some reason, ISeqs on stack are sometimes GC-ed (why?) and therefore
    it may run mjit_recompile on a GC-ed ISeq, which I expected d07183ec85d
    to fix but apparently it may refer to random things if already GC-ed.
    Marking active_units would workaround the situation.
    http://ci.rvm.jp/results/trunk-mjit-wait@phosphorus-docker/3292740

    Also, while compact_all_jit_code was executed, we saw some SEGVs where
    CCs seemed to be already GC-ed, meaning their owner ISeq was not marked
    properly. Even if units are still in active_units, it's not guaranteed
    that their ISeqs are in use. So in this case we need to mark active_units
    for a legitimate reason.

    Stop marking unit_queue

    The original motivation of this marking was https://github.com/k0kubun/yarv-mjit/issues/20.
    As wanabe said, there are multiple options to mitigate the issue, and
    Eric Wong introduced another fix at 143776f6fe by checking unit->iseq
    inside the lock.

    Therefore this particular condition has been covered in two ways, and
    the script given by wanabe no longer crashes without mjit_mark().

    [ruby/irb] Add measure command

    You can use "measure" command to check performance in IRB like below:

      irb(main):001:0> 3
      => 3
      irb(main):002:0> measure
      TIME is added.
      => nil
      irb(main):003:0> 3
      processing time: 0.000058s
      => 3
      irb(main):004:0> measure :off
      => nil
      irb(main):005:0> 3
      => 3

    You can set "measure :on" by "IRB.conf[:MEASURE] = true" in .irbrc, and, also,
    set custom performance check method:

      IRB.conf[:MEASURE_PROC][:CUSTOM] = proc { |context, code, line_no, &block|
        time = Time.now
        result = block.()
        now = Time.now
        puts 'custom processing time: %fs' % (Time.now - time) if IRB.conf[:MEASURE]
        result
      }

    add "copy: true" option for Ractor.make_shareable

    Ractor.make_shareable(obj) tries to make obj a shareable object
    by changing the attribute of obj and traversable objects from obj
    (mainly freeze them).

    "copy: true" option is more conservative approach by make deep
    copied object and make it sharable. It doesn't affect any existing
    objects.

    Use category: :experimental in warnings that are related to experimental features

    This adds rb_category_compile_warn in order to emit compiler warnings
    with categories.  Note that Ripper currently ignores the category
    for these warnings, but by default it ignores the warnings completely,
    so this shouldn't matter.

    Use category: :deprecated in warnings that are related to deprecation

    Also document that both :deprecated and :experimental are supported
    :category option values.

    The locations where warnings were marked as deprecation warnings
    was previously reviewed by shyouhei.

    Comment a couple locations where deprecation warnings should probably
    be used but are not currently used because deprecation warning
    enablement has not occurred at the time they are called
    (RUBY_FREE_MIN, RUBY_HEAP_MIN_SLOTS, -K).

    Add assert_deprecated_warn to test assertions.  Use this to simplify
    some tests, and fix failing tests after marking some warnings with
    deprecated category.

    Switch rb_category_warn{,ing} to accept an rb_warning_category_t

    Since we decided to only allowing specific warning categories,
    there is no reason to have an API that accepts a general string,
    as it is more error-prone.  Switch to only allowing the specific
    warning categories.

    As rb_category_warn{,ing} are public API, this requires making
    rb_warning_category_t public API as well.

    Ractor#receive can be called by the another Ractors using send,
    so making this method completely same as `Ractor.receive` even if
    the ractor is specified by the receiver (OO term :p).

    Import bigdecimal 2.0.2 (#3905)

    * remove duplicated include

    * Make BigDecimal#round with argument < 1 return Integer

    Fixes [Bug #12780]

    * Use a higher default precision for BigDecimal#power and #**

    When a fractional power is given, increase the precision if the
    precision isn't specified via power's second argument:

    Float: increase by 15 (rough number of decimal precision in float)
    BigDecimal: increase by adding similar precision modifier as done to
                calculate the base precision.
    Rational: double the precision, since a BigDecimal is created, but
              the created BigDecimal uses the same precision.

    Increasing the precision for these power calculations has the obvious
    tradeoff of making the calculations slower.

    Fixes Ruby Bug #17264

    * Use DBLE_FIG for a Float value

    * Version 2.0.1

    fix inline method cache sync bug

    `cd` is passed to method call functions to method invocation
    functions, but `cd` can be manipulated by other ractors simultaneously
    so it contains thread-safety issue.

    To solve this issue, this patch stores `ci` and found `cc` to `calling`
    and stops to pass `cd`.

    Skip defined check in NODE_OP_ASGN_OR with ivar

    Previously we would add code to check if an ivar was defined when using
    `@foo ||= 123`, which was slower than `@foo || (@foo = 123)` when `@foo`
    was already defined.

    Recently 01b7d5acc702df22d306ae95f1a9c3096e63e624 made it so that
    accessing an undefined variable no longer generates a warning, making
    the defined check unnecessary and both statements exactly equal.

    This commit avoids emitting the defined instruction when compiling
    NODE_OP_ASGN_OR with a NODE_IVAR.

    Before:

        $ ruby --dump=insn -e '@foo ||= 123'
        == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE)
        0000 putnil                                                           (   1)[Li]
        0001 defined                      instance-variable, :@foo, false
        0005 branchunless                 14
        0007 getinstancevariable          :@foo, <is:0>
        0010 dup
        0011 branchif                     20
        0013 pop
        0014 putobject                    123
        0016 dup
        0017 setinstancevariable          :@foo, <is:0>
        0020 leave

    After:

        $ ./ruby --dump=insn -e '@foo ||= 123'
        == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE)
        0000 getinstancevariable                    :@foo, <is:0>             (   1)[Li]
        0003 dup
        0004 branchif                               13
        0006 pop
        0007 putobject                              123
        0009 dup
        0010 setinstancevariable                    :@foo, <is:0>
        0013 leave

    This seems to be about 50% faster in this benchmark:

        require "benchmark/ips"

        class Foo
          def initialize
            @foo = nil
          end

          def test1
            @foo ||= 123
          end

          def test2
            @foo || (@foo = 123)
          end
        end

        FOO = Foo.new

        Benchmark.ips do |x|
          x.report("test1", "FOO.test1")
          x.report("test2", "FOO.test2")
        end

    trap on non-main ractor

    trap can accept blopck/Proc and it can violate Rator isolation,
    so the Proc should be isolatable when trap is used on non-main ractor.

    addr2line.c: support debuglink by build_id

    Currently, addr2line.c supports only one path format of debuglink:
    "/usr/lib/debug/usr/bin/ruby.debug".

    However, recent debian packages seem to use another format by build_id:
    "/usr/lib/debug/.build-id/ab/cdef1234.debug".

    https://github.com/Debian/debhelper/blob/5d1bb29841043d8e47ebbdd043e6cd086cad508e/dh_strip#L353

    Link zlib always if available

    Major Linux distribution packages including Debian, Ubuntu, and Fedora
    use `--compress-debug-sections=no` to build ruby, and then extract and
    compress debug symbols as separate files. However, the configure option
    makes ruby not link zlib, thus the generated binary cannot uncompress
    the compressed separate debug symbol files, and fails to show C level
    backtrace when a critical error like segfault occurs.

    This change makes ruby always link zlib if it is available so that it
    can show C level backtrace correctly.

    Related: Debian packages require https://github.com/ruby/ruby/pull/3627
    to load debug symbol files.

    ```

    Details:

    In short, it is an uninitialized variable bug.

    Until GCC 7, all function locations are represented by a pair of
    DW_AT_low_pc and DW_AT_high_pc in DWARF information.
    But since GCC 8, some functions are split to multiple chunks, which are
    represented by DW_AT_ranges.
    DW_AT_ranges are represented as offsets from a base address.
    According to DWARF specification, it is the base address of the
    compilation unit, but GCC seems to use zero as default.
    The function "di_read_cu" in addr2line.c had a comment about the fact.
    However, the base address wasn't initialized as zero.

    ObjectSpace._id2ref should not support unshareable

    ObjectSpace._id2ref(id) can return any objects even if they are
    unshareable, so this patch raises RangeError if it runs on multi-ractor
    mode and the found object is unshareable.

    cache free pages per ractor

    Per ractor method cache (GH-#3842) only cached 1 page and this patch
    caches several pages to keep at least 512 free slots if available.
    If you increase the number of cached free slots, all cached slots
    will be collected when the GC is invoked.

    [ruby/prime] Optimize `Integer#prime?`

    Miller Rabin algorithm can be used to test primality for integers smaller than a max value "MaxMR" (~3e24)

    It can be much faster than previous implementation: ~100x faster for numbers with 13 digits, at least 5 orders of magnitude for even larger numbers (previous implementation is so slow that it requires more patience than I have for more precise estimate).

    Miller Rabin test becomes faster than previous implementation at somewhere in the range 1e5-1e6. It seems that the range 62000..66000 is where Miller Rabin starts being always faster, so I picked 0xffff arbitrarily; before that, or above "MaxMR", the previous implementation remains.

    I compared the `faster_prime` gem too. It is slower than previous implementation up to ~1e4. After that it becomes faster and faster compared to previous implementation, but is still slower than Miller Rabin starting at ~1e5 and up to MaxMR. Thus, after this commit, builtin `Integer#prime?` will be similar or faster than `faster_prime` up to "MaxMR".

    Windows: Read ENV names and values as UTF-8 encoded Strings (#3818)

    * Windows: Read ENV names and values as UTF-8 encoded Strings

    Implements issue #12650: fix https://bugs.ruby-lang.org/issues/12650

    This also removes the special encoding for ENV['PATH'] and some
    complexity in the code that is unnecessary now.

    * Windows: Improve readablity of getenv() encoding

    getenv() did use the expected codepage as an implicit parameter of the macro.
    This is mis-leading since include/ruby/win32.h has a different definition.
    Using the "cp" variable explicit (like the other function calls) makes it
    more readable and consistent.

    * Windows: Change external C-API macros getenv() and execv() to use UTF-8

    They used to process and return strings with locale encoding,
    but since all ruby-internal spawn and environment functions use UTF-8,
    it makes sense to change the C-API equally.

    RB_VM_LOCK_ENTER_NO_BARRIER

    Write barrier requires VM lock because it accesses VM global bitmap
    but RB_VM_LOCK_ENTER() can invoke GC because another ractor can wait
    to invoke GC and RB_VM_LOCK_ENTER() is barrier point. This means that
    before protecting by a write barrier, GC can invoke.
    To prevent such situation, RB_VM_LOCK_ENTER_NO_BARRIER() is introduced.
    This lock primitive does not become GC barrier points.

    per-ractor object allocation

    Now object allocation requires VM global lock to synchronize objspace.
    However, of course, it introduces huge overhead.
    This patch caches some slots (in a page) by each ractor and use cached
    slots for object allocation. If there is no cached slots, acquire the global lock
    and get new cached slots, or start GC (marking or lazy sweeping).

    Call cleanup function for getaddrinfo_a(3) only before fork()

    Previously, rb_getaddrinfo_a_before_exec() is called from before_exec().
    However, the function needs to be called only before fork().
    The change moves it to before_fork().

    Avoiding recursive call would imply iterating bits starting from

    [ruby/fileutils] Make mkdir_p only attempt to create necessary directories

    Previously, if creating the directory directly didn't work
    and the directory didn't exist, mkdir_p would create all
    directories from the root.  This modifies the approach to
    check whether the directory exists when walking up the
    directory tree from the argument, and once you have found an
    intermediate directory that exists, you only need to create
    directories under it.

    This approach has a couple advantages:

    1) It performs better when most directories in path already exist,
    and that will be true for most usage of mkdir_p, as mkdir_p is
    usually called with paths where the first few directories exist
    and only the last directory or last few directories do not.

    2) It works in file-system access limited environments such as
    when unveil(2) is used on OpenBSD.  In these environments, if
    /foo/bar/baz exists and is unveiled, you can do
    `mkdir /foo/bar/baz/xyz` but `mkdir /foo` and `mkdir /foo/bar` raise
    Errno::ENOENT.

    [ruby/set] Remove SortedSet implementations

    It required RBTree to perform decently and the external dependency was
    not suitable for a standard library.  The pure ruby fallback
    implementation was originally meant to be an example of how to write a
    subclass of Set, and its poor performance was not suitable for use in
    production.

    I decided it should be distributed as an external library instead of
    bundling it with Set.

    fix initialize order

    `captured->code.val` should be initialize before because it can be
    a GC point by another ractor because `RB_OBJ_WRITE` can issue
    VM locking.

    Do not require time and fileutils by default

    I have no idea what I'm doing, but the previous commit caused lots of CI
    failures like https://github.com/ruby/ruby/runs/1496949568 and this
    place is the most suspicious.

    Save a core file on a worker crash

    CI failures like
    http://ci.rvm.jp/results/trunk-mjit@phosphorus-docker/3280458 doesn't
    provide any useful information, and it doesn't leave a core file in a CI
    environment because a test like `Process.kill(:TRAP, $$)` overwrites in
    a next run very quickly.

    Thus I'd like to keep core files in /tmp.

    Do not reduce quantifiers if it affects which text will be matched

    Quantifier reduction when using +?)* and +?)+ should not be done
    as it affects which text will be matched.

    This removes the need for the RQ_PQ_Q ReduceType, so remove the
    enum entry and related switch case.

    Test that these are the only two patterns affected by testing all
    quantifier reduction tuples for both the captured and uncaptured
    cases and making sure the matched text is the same for both.

    Don't fail when 'did_you_mean' is not available.

    Although 'did_you_mean' is always available in upstream Ruby, it might
    not be available when speed, memory, disk or network bandwidth is a
    concern. This is typically the case for production environment, where
    'did_you_mean' is of limited usage.

    Also it might not be available optionally when Ruby is delivered via
    packaging systems. E.g. Linux distributions.

    digest: remove OpenSSL engine

    The OpenSSL engine of Digest uses the low-level API of OpenSSL, whose
    use has been discouraged for years for multiple reasons.

    A long-standing issue on a FIPS-enabled system is that using ::Digest
    results in crashing the Ruby process, because the low-level API lacks
    the mechanism to report an error (the policy violation) and thus kills
    the process as a last resort[1][2]. Also, the upcoming OpenSSL 3.0 will
    deprecate it for future removal[3]. Compiling with
    -Wdeprecated-declarations will start to emit warnings.

    A proper fix for this is to make it use the EVP API instead. This is a
    non-trivial work as it requires backwards-incompatible changes to the
    framework interface of Digest::Base and rb_digest_metadata_t.

    It is more than 15 years ago that the openssl library became part of the
    standard library. It has implemented the exactly same functionality as
    OpenSSL::Digest, in fact, as a subclass of Digest::Class. There is not
    much point in having an identical code in the digest library. Let's
    just get rid of OpenSSL within digest. This leaves the C implementations
    and the CommonCrypto engine for Apple systems.

    A patch is being prepared for the openssl library to provide ::Digest
    constants for better performance[4].

    rb_ext_ractor_safe() to declare ractor-safe ext

    C extensions can violate the ractor-safety, so only ractor-safe
    C extensions (C methods) can run on non-main ractors.
    rb_ext_ractor_safe(true) declares that the successive
    defined methods are ractor-safe. Otherwiwze, defined methods
    checked they are invoked in main ractor and raise an error
    if invoked at non-main ractors.

    ractor_copy() used rb_ary_modify() to make sure this array is not
    sharing anything, but it also checks frozen flag. So frozen arrays
    raises an error. To solve this issue, this patch introduces new
    function rb_ary_cancel_sharing() which makes sure the array does not
    share another array and it doesn't check frozen flag.

    ractor local storage C-API

    To manage ractor-local data for C extension, the following APIs
    are defined.

    * rb_ractor_local_storage_value_newkey
    * rb_ractor_local_storage_value
    * rb_ractor_local_storage_value_set
    * rb_ractor_local_storage_ptr_newkey
    * rb_ractor_local_storage_ptr
    * rb_ractor_local_storage_ptr_set

    At first, you need to create a key of storage by
    rb_ractor_local_(value|ptr)_newkey().
    For ptr storage, it accepts the type of storage,
    how to mark and how to free with ractor's lifetime.

    rb_ractor_local_storage_value/set are used to access a VALUE
    and rb_ractor_local_storage_ptr/set are used to access a pointer.

    random.c uses this API.

    tune parallel test

    (1) Add "--timetable-data=FILE" option for test-all
        This option enables to dump timeline event
        contains worker, suite, and start/end time.
    (2) remove TestJIT in test_jit_debug.rb on parallel test.
        it is duplicated test.
    (3) move test_jit.rb and test_jit_debug.rb at first
        because these two tests are bottleneck of parallel tests.

    On my environment, `make test-all TESTS=-j12` reduced the total time
    190 seconds -> 140 seconds.

    The vm mark function should only check if the current frame is a local
    or not and then mark values in that frame.  Since it's walking up the
    stack looking at each cfp, then all ep's should be examined.

    This fixes a bug in the Rails tests where we're seeing segv in railties.

    Windows: Improve readablity of getenv() encoding

    getenv() did use the expected codepage as an implicit parameter of the macro.
    This is mis-leading since include/ruby/win32.h has a different definition.
    Using the "cp" variable explicit (like the other function calls) makes it
    more readable and consistent.

    Fix compactions.size for throttling

    Throttle JIT compaction

    The compilation for JIT compaction is very heavy. Triggering a second
    compaction to include one more new method is probably not worth it. So
    this triggers JIT compaction for ten more new methods after each
    compaction.

    Throttle unload_units

    Because d80226e7bd often reduces the number of unloaded units, it
    increases the number of unload_units calls, which are heavy.

    To mitigate that, this throttles unload_units per `max_cache_size / 10`.

    Don't double fractional seconds when passing timezone object to Time.new

    I found that fractional seconds were doubled when using the timezone
    feature of Time in Sequel's named_timezones extension (which uses
    TZInfo for the timezone object), and traced the problem to this code.

    There is no subsecx being modified in the utc_to_local call below
    this, and I'm not sure why you would want to add in the fractional
    seconds unless you assumed the timezone conversion would drop the
    existing fractional seconds (TZInfo doesn't drop fractional seconds).

    Moving some functions from mjit.c to mjit_worker.c because mjit_worker.c
    should have functions executed in the JIT worker.

    per-ractor Random::DEFAULT

    Random generators are not Ractor-safe, so we need to prepare
    per-ractor default random genearators. This patch set
    `Random::DEFAULT = Random` (not a Random instance, but the Random
    class) and singleton methods like `Random.rand()` use a per-ractor
    random generator.

    Disable auto compaction on platforms that can't support it

    Both explicit compaction routines (gc_compact and the verify references form)
    need to clear the heap before executing compaction.  Otherwise some
    objects may not be alive, and we'll need the read barrier.  The heap
    must only contain *live* objects if we want to disable the read barrier
    during explicit compaction.

    The previous commit was missing the "clear the heap" phase from the
    "verify references" explicit compaction function.

    Fixes [Bug #17306]

    should stop other ractors on transient_heap_evacuate

    transient_heap_evacuate() evacuates all living objects from theap
    to malloc managed memory. This evacuation can run in any ractors
    in parallel with other ractor's execution and it is danger.

    To stop such danger parallel execution, use rb_vm_barrier() to
    stop all other ractors.

    Ractor's error will be printed if Thread#report_on_exception

    the exception object is sent by Ractor.yield and it can be shared

    To prevent such sharing, show errors befor Ractor.yield().

    Report a full_message on a worker crash

    A worker crash happens very often, but we're not sure why.
    I'd like to know a backtrace if it's available.

    Skip test_ractor.rb:137 for --jit-min-calls=5

    It's failing like
    http://ci.rvm.jp/results/trunk-mjit-wait@phosphorus-docker/3270373 but I
    have no bandwidth to fix it for now.

    We're still checking --jit-wait (without --jit-min-calls=5) on GitHub
    Actions.

    Report a more detailed situation of test_ractor.rb:137

    This test has been very unstable. I'd like to instantly know whether
    it's always failing or random when I look at a CI failure output.

commit 63ad55cd882e4010fe313d271af006a430b5ffa8

    Disable auto compaction on platforms that can't support it

    Auto Compaction uses mprotect to implement a read barrier.  mprotect can
    only work on regions of memory that are a multiple of the OS page size.
    Ruby's pages are a multiple of 4kb, but some platforms (like ppc64le)
    don't have 4kb page sizes.  This commit disables the features on those
    platforms.

    Fixes [Bug #17306]

  Author: Aaron Patterson <tenderlove@ruby-lang.org>
  Date:   2020-11-25 03:45:12 +0900

    Disable read barrier on explicit compaction request

    We don't need a read barrier when the user calls `GC.compact` because we
    don't allow allocations during GC, and all references should be "live"

    convert_unit_to_func's c_func / so_func construction is unnecessarily

    compact_all_jit_code.

    Make sure all threads are scanned on unload_units

    This has been a TODO since 79df14c04b. While adcf0316d1 covered the
    root_fiber of the initial thread, it didn't cover root_fibers of other
    threads. Now it's hooked properly in rb_threadptr_root_fiber_setup.

    With regards to "XXX: Is this mjit_cont `mjit_cont_free`d?", when
    rb_threadptr_root_fiber_release is called, although I'm not sure when
    th->root_fiber is truthy, fiber_free seems to call cont_free and
    mjit_cont_free. So mjit_conts of root_fibers seem to be freed properly.

    Unify some confusing macro usages

    _MSC_VER used to be the macro to switch JIT compaction. However, since
    d4381d2ceb, the correct macro to switch it was changed from _MSC_VER
    to _WIN32. As I didn't properly replace all relevant _MSC_VER usages
    to _WIN32, these macros have been used inconsistently.

    nobu replaced _WIN32 with USE_HEADER_TRANSFORMATION in 5eb446d12f3.
    Therefore we had USE_HEADER_TRANSFORMATION and _MSC_VER. This commit
    makes sure such inconsistent _MSC_VER usages will be unified to the new
    header, also renaming it to USE_JIT_COMPACTION to be more precise about
    the requirements. The header transformation itself is not quite relevant
    to places changed in this commit.

    Shrink the blocking region for compile_compact_jit_code

    Isn't setting `in_compact = true` enough to avoid a race condition
    between JIT compaction and unload_units? Now I think it is.

    This change will make it easier to spend more time on compile_compact_jit_code.
    For now it seems to take only 0.0723ms though.

    Make String methods return String instances when called on a subclass instance

    This modifies the following String methods to return String instances
    instead of subclass instances:

    * String#*
    * String#capitalize
    * String#center
    * String#chomp
    * String#chop
    * String#delete
    * String#delete_prefix
    * String#delete_suffix
    * String#downcase
    * String#dump
    * String#each/#each_line
    * String#gsub
    * String#ljust
    * String#lstrip
    * String#partition
    * String#reverse
    * String#rjust
    * String#rpartition
    * String#rstrip
    * String#scrub
    * String#slice!
    * String#slice/#[]
    * String#split
    * String#squeeze
    * String#strip
    * String#sub
    * String#succ/#next
    * String#swapcase
    * String#tr
    * String#tr_s
    * String#upcase

    This also fixes a bug in String#swapcase where it would return the
    receiver instead of a copy of the receiver if the receiver was the
    empty string.

    Some string methods were left to return subclass instances:

    * String#+@
    * String#-@

    Both of these methods will return the receiver (subclass instance)
    in some cases, so it is best to keep the returned class consistent.

    Fixes [#10845]

    Do not allow Module#include to insert modules before the origin in the lookup chain

    Module#include should only be able to insert modules after the origin,
    otherwise it ends up working like Module#prepend.

    This fixes the case where one of the modules in the included module
    chain is included in a module that is already prepended to the receiver.

    [ruby/fiddle] Add a "pinning" reference (#44)

    * Add a "pinning" reference

    A `Fiddle::Pinned` objects will prevent the objects they point to from
    moving.  This is useful in the case where you need to pass a reference
    to a C extension that keeps the address in a global and needs the
    address to be stable.

    For example:

    ```ruby
    class Foo
      A = "hi" # this is an embedded string

      some_c_function A # A might move!
    end
    ```

    If `A` moves, then the underlying string buffer may also move.
    `Fiddle::Pinned` will prevent the object from moving:

    ```ruby
    class Foo
      A = "hi" # this is an embedded string

      A_pinner = Fiddle::Pinned.new(A) # :nodoc:

      some_c_function A # A can't move because of `Fiddle::Pinned`
    end
    ```

    This is a similar strategy to what Graal uses:

      https://www.graalvm.org/sdk/javadoc/org/graalvm/nativeimage/PinnedObject.html#getObject--

    * rename global to match exception name

    * Introduce generic Fiddle::Error and rearrange error classes

    Fiddle::Error is the generic exception base class for Fiddle exceptions.
    This commit introduces the class and rearranges Fiddle exceptions to
    inherit from it.

    configure.ac: fix for upcoming autoconf-2.70

    The failure initially noticed on `autoconf-2.69d` (soon to become 2.70):

    ```
    $ ./configure
    ./configure: line 8720: syntax error near unexpected token `fi'
    ./configure: line 8720: `fi'
    ```

    Before the change generated `./configure ` snippet looked like:

    ```
        if ! $CC -E -xc - <<SRC >/dev/null
    then :

            #if defined __APPLE_CC__ && defined __clang_major__ && __clang_major__ < 3
            #error premature clang
            #endif
    SRC
            as_fn_error $? "clang version 3.0 or later is required" "$LINENO" 5
    fi
    ```

    Note the newline that breaks here-document syntax.

    After the change the snippet does not use here-document.

    Set allocator on class creation

    Allocating an instance of a class uses the allocator for the class. When
    the class has no allocator set, Ruby looks for it in the super class
    (see rb_get_alloc_func()).

    It's uncommon for classes created from Ruby code to ever have an
    allocator set, so it's common during the allocation process to search
    all the way to BasicObject from the class with which the allocation is
    being performed. This makes creating instances of classes that have
    long ancestry chains more expensive than creating instances of classes
    have that shorter ancestry chains.

    Setting the allocator at class creation time removes the need to perform
    a search for the alloctor during allocation.

    This is a breaking change for C-extensions that assume that classes
    created from Ruby code have no allocator set. Libraries that setup a
    class hierarchy in Ruby code and then set the allocator on some parent
    class, for example, can experience breakage. This seems like an unusual
    use case and hopefully it is rare or non-existent in practice.

    Rails has many classes that have upwards of 60 elements in the ancestry
    chain and benchmark shows a significant improvement for allocating with
    a class that includes 64 modules.

    Fix singleton class cloning

    Before this commit, `clone` gave different results depending on whether the original object
    had an attached singleton class or not.

    Consider the following setup:
    ```
    class Foo; end
    Foo.singleton_class.define_method(:foo) {}

    obj = Foo.new

    obj.singleton_class if $call_singleton

    clone = obj.clone
    ```

    When `$call_singleton = false`, neither `obj.singleton_class.singleton_class` nor
    `clone.singleton_class.singleton_class` own any methods.

    However, when `$call_singleton = true`, `clone.singleton_class.singleton_class` would own a copy of
    `foo` from `Foo.singleton_class`, even though `obj.singleton_class.singleton_class` does not.

    The latter case is unexpected and results in a visibly different clone, depending on if the original object
    had an attached class or not.

    close_incoming by antoher ractor means there is no other messages

    close_outgoing by antoher ractor means, ... I don't have good idea
    to use it. It can be a private method.

    Ractor#close calls both, but it does not make sense to call
    different purpose methods, so I remove it.

    introduce USE_VM_CLOCK for windows.

    The timer function used on windows system set timer interrupt
    flag of current main ractor's executing ec and thread can detect
    the end of time slice. However, to set all ec->interrupt_flag for
    all running ractors, it is requires to synchronize with other ractors.
    However, timer thread can not acquire the ractor-wide lock because
    of some limitation.

    To solve this issue, this patch introduces USE_VM_CLOCK compile option
    to introduce rb_vm_t::clock. This clock will be incremented by the
    timer thread and each thread can check the incrementing by comparison
    with previous checked clock. At last, on windows platform this patch
    introduces some overhead, but I think there is no critical performance
    issue because of this modification.

    Remove iv table size check

    iv tables cannot shrink.  If the inline cache was ever set, then there
    must be an entry for the instance variable in the iv table.  Just set
    the iv list on the object to be equal to the iv index table size, then
    set the iv.

    eagerly initialize ivar table when index is small enough

    When the inline cache is written, the iv table will contain an entry for
    the instance variable.  If we get an inline cache hit, then we know the
    iv table must contain a value for the index written to the inline cache.

    If the index in the inline cache is larger than the list on the object,
    but *smaller* than the iv index table on the class, then we can just
    eagerly allocate the iv list to be the same size as the iv index table.

    This avoids duplicate work of checking frozen as well as looking up the
    index for the particular instance variable name.

    When a scheduler is present, it's entirely possible for
    `th->keeping_mutexes` to be updated while enumerating the waitq. Therefore

    Add support for IPv6 link local addresses to resolv

    Now that it should work correctly, test that every address returned
    by Socket.ip_address_list is resolvable.

    Socket works with IPv6 link local addresses, and ipaddr now does
    as well, so I think resolv should support them.

    Remove sender/message_id pair after response received in resolv

    Once a response for a given DNS request has been received (which
    requires a matching message id), the [sender, message_id] pair
    should be removed from the list of valid senders.  This makes it
    so duplicate responses from the same sender are ignored.

    a part of T_DATA object can Ractor#send

    T_DATA objects can refer unshareable objects and they should be
    copied recursively, however there is no way to replace with copied
    unshareable objects. However, if a T_DATA object refers only
    shareable objects, there is no need to replace. So this kind of
    T_DATA object (such as Time, Dir, File::Status and so on) can be
    sent by Ractor.send.

    Simplify setting instance variables

    Since T_OBJECT objects come to life as embedded objects, that means that
    ROBJECT_NUMIV will always return a _minimum_ of ROBJECT_EMBED_LEN_MAX.
    If ivup.index is *greater* than ROBJECT_NUMIV, then we know that the
    object *must not* be an embedded object. Thus we can skip the
    ROBJECT_EMBED_LEN_MAX check as well as initializing internals of
    embedded objects.

    Ractor's "will" doesn't need copying.

    `r = Ractor.new{ expr }` generates the block return value from `expr`
    and we can get this value by `r.take`. Ractor.yield and Ractor#take
    passing values by copying on default. However, the block return value
    (we named it "will" in the code) is not referred from the Ractor
    because the Ractor is already dead. So we can pass the reference
    of "will" to another ractor without copying. We can apply same story
    for the propagated exception.

    a method defined by define_method with normal Proc can not cross
    ractors because the normal Proc is not shareable. However,
    shareable Proc can be crossed between ractors, so the method with
    shareable Proc should be called correctly.

    Ractor.make_shareable(a_proc)

    Ractor.make_shareable() supports Proc object if
    (1) a Proc only read outer local variables (no assignments)
    (2) read outer local variables are shareable.

    Read local variables are stored in a snapshot, so after making
    shareable Proc, any assignments are not affeect like that:

    ```ruby
    a = 1
    pr = Ractor.make_shareable(Proc.new{p a})
    pr.call #=> 1
    a = 2
    pr.call #=> 1 # `a = 2` doesn't affect
    ```

    Make ENV.replace handle multiple environ entries with the same key

    While it is expected that all environment keys are unique, that is
    not enforced. It is possible by manipulating environ directly you
    can call a process with an environment with duplicate keys.  If
    ENV.replace was passed a hash with a key where environ had a
    duplicate for that key, ENV.replace would end up deleting the key
    from environ.

    The fix in this case is to not assume that the environment key
    list has unique keys, and continue processing the entire key
    list in keylist_delete.

    As of 0b81a484f3453082d28a48968a063fd907daa5b5, `ROBJECT_IVPTR` will

    one.  T_OBJECTs always come to life as embedded objects, so they will
    return an ivptr, and when they become "unembedded" they will have an
    ivptr at that point too

    Revert "Add assertions when inline caches are copied to MJIT"

    This reverts commit 6cb6d5abc36ede9d5158c2cd90734134838e6bfb.
    This reverts commit 1484b786aee8d411a9e2278ac6d6e44aedbf6662.

    I think we don't need these assertions anymore.  I believe the problem
    is solved by abf678a4397c6c00a1bb686043e377d372e695a4

commit abf678a4397c6c00a1bb686043e377d372e695a4
  Author: Aaron Patterson <tenderlove@ruby-lang.org>
  Date:   2020-10-22 05:16:15 +0900

    Use a lock level for a less granular lock.

    We are seeing an error where code that is generated with MJIT contains
    references to objects that have been moved.  I believe this is due to a
    race condition in the compaction function.

    `gc_compact` has two steps:

    1. Run a full GC to pin objects
    2. Compact / update references

    Step one is executed with `garbage_collect`.  `garbage_collect` calls
    `gc_enter` / `gc_exit`, these functions acquire a JIT lock and release a
    JIT lock.  So a lock is held for the duration of step 1.

    Step two is executed by `gc_compact_after_gc`.  It also holds a JIT
    lock.

    I believe the problem is that the JIT is free to execute between step 1
    and step 2.  It copies call cache values, but doesn't pin them when it
    copies them.  So the compactor thinks it's OK to move the call cache
    even though it is not safe.

    We need to hold a lock for the duration of `garbage_collect` *and*
    `gc_compact_after_gc`.  This patch introduces a lock level which
    increments and decrements.  The compaction function can increment and
    decrement the lock level and prevent MJIT from executing during both
    steps.

    Ractor.make_shareable(obj)

    Introduce new method Ractor.make_shareable(obj) which tries to make
    obj shareable object. Protocol is here.

    (1) If obj is shareable, it is shareable.
    (2) If obj is not a shareable object and if obj can be shareable
        object if it is frozen, then freeze obj. If obj has reachable
        objects (rs), do rs.each{|o| Ractor.make_shareable(o)}
        recursively (recursion is not Ruby-level, but C-level).
    (3) Otherwise, raise Ractor::Error. Now T_DATA is not a shareable
        object even if the object is frozen.

    If the method finished without error, given obj is marked as
    a sharable object.

    To allow makng a shareable frozen T_DATA object, then set
    `RUBY_TYPED_FROZEN_SHAREABLE` as type->flags. On default,
    this flag is not set. It means user defined T_DATA objects are
    not allowed to become shareable objects when it is frozen.

    You can make any object  shareable by setting FL_SHAREABLE flag,
    so if you know that the T_DATA object is shareable (== thread-safe),
    set this flag, at creation time for example. `Ractor` object is one
    example, which is not a frozen, but a shareable object.

    reduce lock for encoding

    To reduce the number of locking for encoding manipulation,
    enc_table::list is split into ::default_list and ::additional_list.
    ::default_list is pre-allocated and no need locking to access to
    the ::default_list. If additional encoding space is needed, use
    ::additional_list and this list need to use locking.
    However, most of case, ::default_list is enough.

    test/rinda/test_rinda.rb: Prevent a callback Proc from being GC'ed

    According to the log of ac803ab55db50ef891e3680680620d01f28a759b, I
    found that a thread terminates silently due to "recycled object" of
    id2ref:

    ```
    "/home/chkbuild/chkbuild/tmp/build/20201017T033002Z/ruby/lib/drb/drb.rb:366:in `_id2ref'"
    "/home/chkbuild/chkbuild/tmp/build/20201017T033002Z/ruby/lib/drb/drb.rb:366:in `to_obj'"
    "/home/chkbuild/chkbuild/tmp/build/20201017T033002Z/ruby/lib/drb/drb.rb:1528:in `to_obj'"
    "/home/chkbuild/chkbuild/tmp/build/20201017T033002Z/ruby/lib/drb/drb.rb:1847:in `to_obj'"
    "/home/chkbuild/chkbuild/tmp/build/20201017T033002Z/ruby/lib/drb/drb.rb:1136:in `method_missing'"
    "/home/chkbuild/chkbuild/tmp/build/20201017T033002Z/ruby/test/rinda/test_rinda.rb:652:in `block in do_reply'"
    ```
    https://rubyci.org/logs/rubyci.s3.amazonaws.com/rhel8/ruby-master/log/20201017T033002Z.log.html.gz

    I believe that this unintentional thread termination has caused
    intermittent timeout failure of `TestRingServer#test_do_reply`.

    The root cause of the "recycled object" issue is a bug of
    `TestRingServer#test_do_reply`.  It creates a callback Proc object but
    does not hold the reference to the object:

    ```
    callback = DRb::DRbObject.new callback
    ```

    The original "callback" object is GC'ed unintentionally.
    I could consistently reproduce this issue on my machine by adding
    `GC.stress = true` at the first of `_test_do_reply` method body.

    This change uses another local variable name, "callback_orig", to keep
    the original Proc object.

    sync RClass::ext::iv_index_tbl

    iv_index_tbl manages instance variable indexes (ID -> index).
    This data structure should be synchronized with other ractors
    so introduce some VM locks.

    This patch also introduced atomic ivar cache used by
    set/getinlinecache instructions. To make updating ivar cache (IVC),
    we changed iv_index_tbl data structure to manage (ID -> entry)
    and an entry points serial and index. IVC points to this entry so
    that cache update becomes atomically.

    Abort on system stack overflow during GC

    Buggy native extensions could have mark functions that cause stack
    overflow. When a stack overflow happens during GC, Ruby used to recover
    by raising an exception, which runs the interpreter. It's not safe to
    run the interpreter during GC since the GC is in an inconsistent state.
    This could cause object allocation during GC, for example.

    Instead of running the interpreter and potentially causing a crash down
    the line, fail fast and abort.

    generic_ivtbl is a process global table to maintain instance variables
    for non T_OBJECT/T_CLASS/... objects. So we need to protect them
    for multi-Ractor execution.

    Hint: we can make them Ractor local for unshareable objects, but

    freeze Encoding objects

    Encoding objects can be accessed in multi-ractors and there is no
    state to mutate. So we can mark it as frozen and shareable.

    sync enc_table and rb_encoding_list

    enc_table which manages Encoding information. rb_encoding_list
    also manages Encoding objects. Both are accessed/modified by ractors
    simultaneously so that they should be synchronized.

    For enc_table, this patch introduced GLOBAL_ENC_TABLE_ENTER/LEAVE/EVAL
    to access this table with VM lock. To make shortcut, three new global
    variables global_enc_ascii, global_enc_utf_8, global_enc_us_ascii are
    also introduced.

    For rb_encoding_list, we split it to rb_default_encoding_list (256 entries)
    and rb_additional_encoding_list. rb_default_encoding_list is fixed sized Array
    so we don't need to synchronized (and most of apps only needs it). To manage
    257 or more encoding objects, they are stored into rb_additional_encoding_list.
    To access rb_additional_encoding_list., VM lock is needed.

    relax Fiber#transfer's restriction

    Using Fiber#transfer with Fiber#resume for a same Fiber is
    limited (once Fiber#transfer is called for a fiber, the fiber
    can not be resumed more). This restriction was introduced to
    protect the resume/yield chain, but we realized that it is too much
    to protect the chain. Instead of the current restriction, we
    introduce some other protections.

    (1) can not transfer to the resuming fiber.
    (2) can not transfer to the yielding fiber.
    (3) can not resume transferred fiber.
    (4) can not yield from not-resumed fiber.

    [Bug #17221]

    Also at the end of a transferred fiber, it had continued on root fiber.
    However, if the root fiber resumed a fiber (and that fiber can resumed
    another fiber), this behavior also breaks the resume/yield chain.
    So at the end of a transferred fiber, switch to the edge of resume
    chain from root fiber.
    For example, root fiber resumed f1 and f1 resumed f2, transferred to
    f3 and f3 terminated, then continue from the fiber f2 (it was continued
    from root fiber without this patch).

    bignum.c (bary_sparse_p): do not comsume Random::DEFAULT

    It uses random to determine if the bignum is sparse or not.
    It is arguable if three-digit samples are enough or not to determine it,
    but anyway, consuming Random source implicitly is not good.

    I introduced the random sampling mechanism, and I don't know any
    significant reason to do so.  So, let's remove it.
    This change makes the sampling points fixed: 40th, 50th, and 60th

    Add missing WB for iseq

    The write barrier wasn't being called for this object, so add the
    missing WB.  Automatic compaction moved the reference because it didn't
    know about the relationship (that's how I found the missing WB).

    Prevent objects from moving while iterating the heap

    This iterator uses an st_table, but if objects move the references in
    the st table won't be updated.  This patch just changes the st table to
    an identity hash.

    Make minor improvements to super

    The changes here include:

    * Using `FL_TEST_RAW` instead of `FL_TEST` in the first check in
    `vm_search_super_method`. While the profile showed us spending a fair
    amount of time here, the subsequent benchmarks didn't show much
    improvement when adding this. Regardless, we know this does less work
    than `FL_TEST` and we know that `FL_TEST_RAW` is safe due to the
    previous check so it's a small but accurate optimization.
    * Set `mid` only once. Both `vm_ci_new_runtime` and `vm_ci_mid` were
    getting the `original_id` for the method entry. We can do this once
    and pass the variable to the 2 callers that need it. This also doesn't
    have a huge performance improvement but cleans up the code a bit.

    Benchmark:

    ```

    Fix a use-after-free bug reported by ASAN

    If a fiber and thread are collected at the same time, the thread might
    get collected first and the pointer on the fiber will go bad.  I don't
    think we need to check whether or not this is the main fiber in order to
    release its stack

    stop Ractor test in test-all

    Ractor changes the interpreter's running mode so now it should
    not use in test-all process which running with many other tests.

    Test with a separating process is one idea, but I'm not sure
    the ruby/ostruct can use this trick.

    Fixed installation failure [Bug #17191]

    Try update and extract bundled gems only when baseruby is
    available.  It should be done only when installing from
    developemental build and not from the tarball, but it is not
    obvious to differentiate them.

    Fix ASAN and don't check SPECIAL_CONST_P

    Heap allocated objects are never special constants.  Since we're walking
    the heap, we know none of these objects can be special.  Also, adding
    the object to the freelist will poison the object, so we can't check
    that the type is T_NONE after poison.

    Pass ASAN options to child environments

    I want to work with ASAN, but some child environments are not inheriting

    environments if specified

    Add rb_category_warn{,ing} for warning messages with categories

    This adds the following C-API functions that can be used to emit
    warnings with categories included:

    ```c
    void rb_category_warn(const char *, const char*, ...)
    void rb_category_warning(const char*, const char*, ...)
    ```

    Internally in error.c, there is an rb_warn_category function
    that will call Warning.warn with the string and the category
    keyword if it doesn't have an arity of 1, and will call
    Warning.warn with just the string if it has an arity of 1.
    This refactors the rb_warn_deprecated{,_to_remove} functions
    to use rb_warn_category.

    This makes Kernel#warn accept a category keyword and pass it
    to Warning.warn, so that Ruby methods can more easily emit
    warnings with categories.  rb_warn_category makes sure that
    the passed category is a already defined category symbol
    before calling Warning.warn.

    The only currently defined warning category is :deprecated,
    since that is what is already used.  More categories can be
    added in later commits.

    Make Warning.warn accept only category keyword

    In general accepting arbitrary keywords is a bad idea unless you are
    delegating keywords or acting on arbitrary keywords.  In this case,
    the category keyword is ignored, and it's less error prone to not
    ignore all keywords.

    Fibers should update themselves on compaction

    We should let fibers update their own references on compaction.  I don't
    think we need the thread to update the associated fiber because there
    will be a fiber object on the heap that knows how to update itself.

    Return nil when argument to ObjectSpace.internal_class_of is T_IMEMO

    The added test case crashes the interpreter because it makes
    ObjectSpace.internal_class_of return the second VALUE slot of an AST
    imemo object. The second VALUE slot of `struct rb_ast_struct` is
    not a VALUE and not a pointer to a Ruby object.

    RBIMPL_ALIGNAS: reorder #ifdef blocks

    Since r63443, `-std=gnu99 -D_XOPEN_SOUCE=x00` is added to Solaris'
    `CPPFLAGS`.  `CPPFLAGS` is shared among `CC` / `CXX`.  This results in
    both `__STDC_VERSION__` and `__cplusplus` to be defined at the same time
    for a C++ compilation, only on Solaris.

    It seems the `CPPFLAGS` addition is intentional.  We should not touch
    that part.  Instead we need to reroute this by always check for
    `__cplusplus` first.

    The memory view interface added at 890bc2cdde is experimental new C-API

    that contains such a numerical array and a bitmap image.  This is
    designed by referring to Python's buffer protocol.

    Remove private_iv_get

    The only remaining use of this function was to get the internal
    message object from an exception's hidden `mesg` instance
    variable to allow it to be dumped wiithout converting to a string.

    As discussed in #103, this exposes internal implementation details
    of CRuby, and ultimately does not provide any real utility to the
    user since they can't directly inspect this hidden variable. The
    test change here is to reflect CRuby behavior that denies equality
    if the internal message objects do not match, as is the case after
    the exception has been loaded and now has a simple String value.

    The impact to users is that exceptions with special hidden message
    objects will convert those objects to String during marshaling
    through YAML. I believe this only affects NameError and its
    descendants, since users can't set this field directly on their
    own exception types.

    Fixes #103.

    ALLOCA_N: do not use RUBY_ALIGNOF

    Now that RUBY_ALIGNOF behaves like C11's _Alignof.  This is not
    necessarily the best stack arrangement.  We can just give up using
    __builtin_alloca_with_align(), and let alloca choose what is optimal.

    RBIMPL_ALIGNOF: do not use __alignof__

    It is reported that on a system of i386 System V ABI, GCC returns 8 for
    __alignof__(double).  OTOH the ABI defines alignments of double to be 4,
    and ISO/IEC 9899:2011 reads that _Alignof(double) shall return 4 on such
    machine.  What we want in ruby is 4 instead of 8 there.  We cannot use
    __alignof__.

    Additionally, both old GCC / old clang return 8 for _Alignof(double) on
    such platforms.  They are their bugs, and already fixed in recent
    versions.  But we have to support older compilers for a while.  Shall
    check sanity of _Alignof.

    [ruby/webrick] Skip env-locale-sensitive CGI test on the "java" platform

    JRuby's environment variables are provided by the Java Development
    Kit's (JDK's) classes, which present them as a map from string to
    string. In order to do this, those environment variable names and
    values must be decoded into characters, which breaks any variables
    that are intended to be "raw" bytes not necessarily decodable with
    the default system encoding.

    This issue is detailed in jruby/jruby#6248. The only solution on
    the JRuby side will be to bypass the JDK environment variable API
    and go directly to the native getenv/setenv system calls. This is
    not likely to happen in the near future, due to the complexity of
    such a change and the rarity of undecodable environment values.

    The exclude here was added due to the Windows platform also having
    a similar sensitivity to character encodings when working with
    environment variables. It seems appropriate to expand this skip
    to the "java" platform, as the root issue is largely the same.

    Improve the performance of super

    This PR improves the performance of `super` calls. While working on some
    Rails optimizations jhawthorn discovered that `super` calls were slower
    than expected.

    The changes here do the following:

    1) Adds a check for whether the call frame is not equal to the method
    entry iseq. This avoids the `rb_obj_is_kind_of` check on the next line
    which is quite slow. If the current call frame is equal to the method
    entry we know we can't have an instance eval, etc.
    2) Changes `FL_TEST` to `FL_TEST_RAW`. This is safe because we've
    already done the check for `T_ICLASS` above.
    3) Adds a benchmark for `T_ICLASS` super calls.
    4) Note: makes a chage for `method_entry_cref` to use `const`.

    On master the benchmarks showed that `super` is 1.76x slower. Our
    changes improved the performance so that it is now only 1.36x slower.

    Benchmark IPS:

    New `vm_iclass_super` benchmark:

    ```
    $ make benchmark ITEM=vm_iclass_super

    ```

    This is the benchmark script used for the benchmark-ips benchmarks:

    ```ruby
    require "benchmark/ips"

    class Foo
      def zuper; end
      def top; end

      last_method = "top"

      ("A".."M").each do |module_name|
        eval <<-EOM
        module #{module_name}
          def zuper; super; end
          def #{module_name.downcase}
            #{last_method}
          end
        end
        prepend #{module_name}
        EOM
        last_method = module_name.downcase

    end

    foo = Foo.new

    Benchmark.ips do |x|

    Receiving UnixSocket works fine if you don't provide a mode, and

    Rudimentary support for disassembling rb_iseq_t

    I need to disassemble instruction sequences while debugging, so I wrote
    this.

    Usage is like this:

    ```
    (lldb) p iseq
    (rb_iseq_t *) $147 = 0x0000000101068400
    (lldb) rbdisasm iseq
    0000 putspecialobject( 3 )
    0002 putnil
    0003 defineclass( ID: 0x560b, (rb_iseq_t *)0x1010681d0, 2 )
    0007 pop
    0008 putspecialobject( 3 )
    0010 putnil
    0011 defineclass( ID: 0x56eb, (rb_iseq_t *)0x101063b58, 2 )
    0015 leave

    Revert "Prevent SystemStackError when calling super in module with activated refinement"

    This reverts commit eeef16e190cdabc2ba474622720f8e3df7bac43b.

    This also reverts the spec change.

    Preventing the SystemStackError would be nice, but there is valid
    code that the fix breaks, and it is probably more common than cases
    that cause the SystemStackError.

    Pin values in the finalizer table

    When finalizers run (in `rb_objspace_call_finalizer`) the table is
    copied to a linked list that is not managed by the GC.  If compaction
    runs, the references in the linked list can go bad.

    Finalizer table shouldn't be used frequently, so lets pin references in
    the table so that the linked list in `rb_objspace_call_finalizer` is
    safe.

    Only interrupt when there is no scheduler in sync_wakeup()

    * When there is a scheduler, the Fiber that would be blocked has already
      been rescheduled and there is no point to interrupt something else.
      That blocked Fiber will be rescheduled as the next call to the scheduler
      (e.g., IO, sleep, other blocking sync).
    * See discussion on https://github.com/ruby/ruby/commit/d01954632d

    Parse ObjectSpace.dump_all / dump arguments in Ruby to avoid allocation noise

    [Feature #17045] ObjectSpace.dump_all should allocate as little as possible in the GC heap

    Up until this commit ObjectSpace.dump_all allocates two Hash because of `rb_scan_args`.

    It also can allocate a `File` because of `rb_io_get_write_io`.

    These allocations are problematic because `dump_all` dumps the Ruby
    heap, so it should try modify as little as possible what it is
    observing.

    Make Mutex per-Fiber instead of per-Thread

    * Enables Mutex to be used as synchronization between multiple Fibers
      of the same Thread.
    * With a Fiber scheduler we can yield to another Fiber on contended
      Mutex#lock instead of blocking the entire thread.
    * This also makes the behavior of Mutex consistent across CRuby, JRuby and TruffleRuby.

    [ruby/irb] Add OMIT_ON_ASSIGNMENT

    Omit the results evaluated at assignment if they are too long.

    The behavior of ECHO_ON_ASSIGNMENT being on by default is hard to understand,
    so I change it to off by default. Instead, we turn OMIT_ON_ASSIGNMENT on by
    default. The result is displayed on assignment, but it will always be short
    and within one line of the screen.

    Let String#slice! return nil (#3533)

    Returns `nil` instead of an empty string when non-integer number is given (to make it 2.7 compatible).

    Make SecureRandom support Ractor

    SecureRandom lazily defines `get_random`.  Accessing the mutex to define
    the `get_random` method is not supported inside a Ractor.  This commit
    defines `gen_random` when `securerandom` is required and makes it
    suppore Ractor (as well as thread safe).

    Here is a test program:

    ```ruby
    require "securerandom"

    r = Ractor.new do
      loop do
        Ractor.yield SecureRandom.hex
      end
    end

    p r.take
    ```

    Make it possible to dump and load an exception object

    A backtrace object in an exception had never supported marshalling
    correctly: `Marshal.load(Marshal.dump(exc)).backtrace_locations` dumped
    core.

    An Exception object has two hidden instance varibles for backtrace data:
    one is "bt", which has an Array of Strings, and the other is
    "bt_locations", which has an Array of Thread::Backtrace::Locations.
    However, Exception's dump outputs data so that the two variables are the
    same Array of Strings. Thus, "bt_locations" had a wrong-type object.

    For the compatibility, it is difficult to change the dump format.  This
    changeset fixes the issue by ignoring data for "bt_locations" at the
    loading phase if "bt_locations" refers to the same object as "bt".

    Future work: Exception's dump should output "bt_locations"
    appropriately.

    check multi_ractor mode at main_p

    rb_ractor_main_p() need to access to the ractor pointer in TLS.
    However it is slow operation so that we need to skip this check
    if it is not multi-ractor mode (!ruby_multi_ractor).

    Avoid potential for rb_raise() while crashing

    rb_obj_raw_info is called while printing out crash messages and
    sometimes called during garbage collection. Calling rb_raise() in these
    situations is undesirable because it can start executing ensure blocks.

    Introduce Ractor mechanism for parallel execution

    This commit introduces Ractor mechanism to run Ruby program in
    parallel. See doc/ractor.md for more details about Ractor.
    See ticket [Feature #17100] to see the implementation details
    and discussions.

    [Feature #17100]

    This commit does not complete the implementation. You can find
    many bugs on using Ractor. Also the specification will be changed
    so that this feature is experimental. You will see a warning when
    you make the first Ractor with `Ractor.new`.

    I hope this feature can help programmers from thread-safety issues.

    Don't call to_s in const_set

    Follow up for 5e16857315bf55307c5fc887ca6f03bfa0630a93. Calling a method
    in the middle of const_set adds a way that it would fail. It also makes

    `to_s`.

    configure: detect that there is no g++

    AC_PROG_CXX checks for several C++ compilers INCLUDING g++.  When none
    of them were found it sets the CXX variable to be g++.  This doesn't
    make any sense.  Absence of g++ has already been made sure.

    Because we don't want insanity (that's the whole reason we test the
    environment using autoconf), we need to swipe such insane variable out.

    support T_MATCH in lldb

commit 0b81a484f3453082d28a48968a063fd907daa5b5

    Initialize new T_OBJECT as ROBJECT_EMBED

    Previously, when an object is first initialized, ROBJECT_EMBED isn't
    set. This means that for brand new objects, ROBJECT_NUMIV(obj) is 0 and
    ROBJECT_IV_INDEX_TBL(obj) is NULL.

    Previously, this combination meant that the inline cache would never be
    initialized when setting an ivar on an object for the first time since
    iv_index_tbl was NULL, and if it were it would never be used because
    ROBJECT_NUMIV was 0. Both cases always fell through to the generic
    rb_ivar_set which would then set the ROBJECT_EMBED flag and initialize
    the ivar array.

    This commit changes rb_class_allocate_instance to set the ROBJECT_EMBED
    flag on the object initially and to initialize all members of the
    embedded array to Qundef. This allows the inline cache to be set
    correctly on first use and to be used on future uses.

    This moves rb_class_allocate_instance to gc.c, so that it has access to
    newobj_of. This seems appropriate given that there are other allocating
    methods in this file (ex. rb_data_object_wrap, rb_imemo_new).

    Add category to `rb_warn_deprecated`

    PR https://github.com/ruby/ruby/pull/3418 added a category to
    `rb_warn_deprecated_to_remove` but not to `rb_warn_deprecated`. This
    adds the same code to `rb_warn_deprecated` so that those warnings also
    get a category.

    This change also adds tests for `rb_warn_deprecated` and updates the
    tests for `rb_warn_deprecated_to_remove` to have clearer names.

    I've fixed the call to `rb_method_entry` as we need to be using the
    instance method, not singleton.

    Support passing a category to `Warning.warn`

    This change adds a `category` kwarg to make it easier to monkey patch
    `Warning.warn`. Warnings already have a category, but that warning isn't
    exposed. This implements a way to get the category so that warnings with
    a specific category, like deprecated, can be treated differently than
    other warnings in an application.

    The change here does an arity check on the method to support backwards
    compatibility for applications that may already have a warning monkey
    patch.

    For our usecase we want to `raise` for deprecation warnings in order to
    get the behavior for the next Ruby version. For example, now that we
    fixed all our warnings and deployed Ruby 2.7 to production, we want to
    be able to have deprecation warnings behave like they would in 3.0: raise
    an error. For other warnings, like uninialized constants, that behavior
    won't be removed from Ruby in the next version, so we don't need to
    raise errors.

    Improve performance of partial backtraces

    Previously, backtrace_each fully populated the rb_backtrace_t with all
    backtrace frames, even if caller only requested a partial backtrace
    (e.g. Kernel#caller_locations(1, 1)).  This changes backtrace_each to
    only add the requested frames to the rb_backtrace_t.

    To do this, backtrace_each needs to be passed the starting frame and
    number of frames values passed to Kernel#caller or #caller_locations.

    backtrace_each works from the top of the stack to the bottom, where the
    bottom is the current frame.  Due to how the location for cfuncs is
    tracked using the location of the previous iseq, we need to store an
    extra frame for the previous iseq if we are limiting the backtrace and
    final backtrace frame (the first one stored) would be a cfunc and not
    an iseq.

    To limit the amount of work in this case, while scanning until the start
    of the requested backtrace, for each iseq, store the cfp.  If the first
    backtrace frame we care about is a cfunc, use the stored cfp to find the
    related iseq.  Use a function pointer to handle the storage of the cfp
    in the iteration arg, and also store the location of the extra frame
    in the iteration arg.

    backtrace_each needs to return int instead of void in order to signal
    when a starting frame larger than backtrace size is given, as caller
    and caller_locations needs to return nil and not the empty array in
    these cases.

    To handle cases where a range is provided with a negative end, and the
    backtrace size is needed to calculate the result to pass to
    rb_range_beg_len, add a backtrace_size static function to calculate
    the size, which copies the logic from backtrace_each.

    As backtrace_each only adds the backtrace lines requested,
    backtrace_to_*_ary can be simplified to always operate on the entire
    backtrace.

    Previously, caller_locations(1,1) was about 6.2 times slower for an
    800 deep callstack compared to an empty callstack.  With this new
    approach, it is only 1.3 times slower. It will always be somewhat
    slower as it still needs to scan the cfps from the top of the stack
    until it finds the first requested backtrace frame.

    This initializes the backtrace memory to zero.  I do not think this is
    necessary, as from my analysis, nothing during the setting of the
    backtrace entries can cause a garbage collection, but it seems the
    safest approach, and it's unlikely the performance decrease is
    significant.

    This removes the rb_backtrace_t backtrace_base member. backtrace
    and backtrace_base were initialized to the same value, and neither
    is modified, so it doesn't make sense to have two pointers.

    This also removes LOCATION_TYPE_IFUNC from vm_backtrace.c, as
    the value is never set.

    Fix Method#super_method for aliased methods

    Previously, Method#super_method looked at the called_id to
    determine the method id to use, but that isn't correct for
    aliased methods, because the super target depends on the
    original method id, not the called_id.

    Additionally, aliases can reference methods defined in other
    classes and modules, and super lookup needs to start in the
    super of the defined class in such cases.

    This adds tests for Method#super_method for both types of
    aliases, one that uses VM_METHOD_TYPE_ALIAS and another that
    does not.  Both check that the results for calling super
    methods return the expected values.

    To find the defined class for alias methods, add an rb_ prefix
    to find_defined_class_by_owner in vm_insnhelper.c and make it
    non-static, so that it can be called from method_super_method
    in proc.c.

    This bug was original discovered while researching [Bug #11189].

    Fixes [Bug #17130]

    Make Socket.getaddrinfo interruptible (#2827)

    Before, Socket.getaddrinfo was using a blocking getaddrinfo(3) call.
    That didn't allow to wrap it into Timeout.timeout or interrupt the thread in any way.

    Combined with the default 10 sec resolv timeout on many Unix systems, this can
    have a very noticeable effect on production Ruby apps being not
    resilient to DNS outages and timing out name resolution, and being unable to fail fast even
    with Timeout.timeout.

    Since we already have support for getaddrinfo_a(3), the async version
    of getaddrinfo, we should be able to make Socket.getaddrinfo leverage that
    when getaddrinfo_a version is available in the system (hence #ifdef
    HAVE_GETADDRINFO_A).

    Correctly account for heap_pages_final_slots so it does not underflow

    `rb_objspace_call_finalizer` creates zombies, but does not do the correct accounting (it should increment `heap_pages_final_slots` whenever it creates a zombie). When we do correct accounting, `heap_pages_final_slots` should never underflow (the check for underflow was introduced in 39725a4db6b121c7779b2b34f7da9d9339415a1c).

    The implementation moves the accounting from the functions that call `make_zombie` into `make_zombie` itself, which reduces code duplication.

    Update PTY.open documentation to document it yields a single argument [ci skip]

    For a regular block, accepting two arguments is fine as the array
    will be autosplatted.   However, a lambda that accepts two arguments
    will not work.

    We could change the implementation to yield two arguments instead
    of an array with a single argument, but that would be less backwards
    compatible.

    I'm only changing the call-seq to be precise, other examples pass
    a literal block that accepts two arguments, and I left those alone
    as that will be the most common usage.

    .github/workflows/compilers.yml: more compilers

    Added some cross compilers that we can run on GitHub Workflow runner
    environments.  Because they are cross compilers we cannot run the
    generated binary.  The added matrix are compile-only.

    protect CFLAGS from being smashed by AC_PROG_CC

    AC_PROG_CC_C99 calls AC_PROC_CC, which calls _AC_PROG_CC_G, which sets
    default CFLAGS, whose contents are not customisable.  We don't welcome
    this behaviour.

    The exact same thing happens for CXXFLAGS in AC_PROG_CXX.

    do not test --version

    `llvm-strip-7` is a sane valid strip command that LLVM 7 ships, albeit
    it does not understand `--version`.  It is a bad idea to check that
    option.  Instead just see if the command actually strips something.  A
    copy of `/bin/sh` should suffice.  That file must be ubiquitous.

    configure.ac: try GCC-provided ld

    In case of cross-compilation, GCC might provide its own linker.  Its
    behaviour seems slightly different from that of gcc(1).  This is not a
    big deal for normal situations, but the difference can cause libtool to
    go mad.

    We ship bundled libffi for windows users, and libffi uses libtool.  If
    we use cross-compiler version of gcc instead of its ld conterpart, we
    fail to compile fiddle.  That should not be what we want.

    configure.ac: move program_transform_name

    Historically `$program_transform_name` has been put in front of
    `AC_CANONICAL_TARGET`.  Previous commit changes it, which affects the
    name of generated ruby binary when cross-compiling.  I _guess_ the
    historical behaviour is a bug (name of ruby binary shall honour --target
    configure option I think), but anyways here I preserve that questionable
    way.

    configure.ac: use compiler-provided toolchains

    These days as link-time optimisations spread across compilers, they
    tend to ship their own version of ld, ar, etc.  Why not detect such
    things if any.  Users can select compilers by ./configure --with-gcc=
    whatever, or select individual tool by e.g. ./configure NM=whatever.

    The added AC_ARG_VAR macros enrich ./configure --help output.

    Update references when tracing allocations

    The allocation tracing code keeps essentially a weak reference to
    objects that have been allocated (storing the allocation information
    along with the weak ref).  Compacting the heap would break references in
    this weak map, so the wrong values could be returned.

    This commit just updates the values in the weak ref in order to fix the
    allocation tracing book keeping

    Remove write barrier exemption for T_ICLASS

    Before this commit, iclasses were "shady", or not protected by write
    barriers. Because of that, the GC needs to spend more time marking these
    objects than otherwise.

    Applications that make heavy use of modules should see reduction in GC
    time as they have a significant number of live iclasses on the heap.

     - Put logic for iclass method table ownership into a function
     - Remove calls to WB_UNPROTECT and insert write barriers for iclasses

    This commit relies on the following invariant: for any non oirigin
    iclass `I`, `RCLASS_M_TBL(I) == RCLASS_M_TBL(RBasic(I)->klass)`. This
    invariant did not hold prior to 98286e9 for classes and modules that
    have prepended modules.

    [Feature #16984]

    Fix method name escaping in ObjectSpace.dump

    It's possible to define methods with any name, even if the parser
    doesn't support it and it can only be used with ex. send.

    This fixes an issue where invalid JSON was output from ObjectSpace.dump
    when a method name needed escaping.

    rb_str_{index,rindex}_m: Handle /\K/ in pattern

    When the pattern Regexp given to String#index and String#rindex
    contain a /\K/ (lookbehind) operator, these methods return the
    position where the beginning of the lookbehind pattern matches, while
    they are expected to return the position where the \K matches.

    ```
    # without patch
    "abcdbce".index(/b\Kc/)  # => 1
    "abcdbce".rindex(/b\Kc/)  # => 4
    ```

    This patch fixes this problem by using BEG(0) instead of the return
    value of rb_reg_search.

    ```
    # with patch
    "abcdbce".index(/b\Kc/)  # => 2
    "abcdbce".rindex(/b\Kc/)  # => 5

    rb_str_{partition,rpartition}_m: Handle /\K/ in pattern

    When the pattern given to String#partition and String#rpartition
    contain a /\K/ (lookbehind) operator, the methods return strings
    sliced at incorrect positions.

    ```
    # without patch
    "abcdbce".partition(/b\Kc/)  # => ["a", "c", "cdbce"]
    "abcdbce".rpartition(/b\Kc/)  # => ["abcd", "c", "ce"]
    ```

    This patch fixes the problem by using BEG(0) instead of the return
    value of rb_reg_search.

    ```
    # with patch
    "abcdbce".partition(/b\Kc/)  # => ["ab", "c", "dbce"]
    "abcdbce".rpartition(/b\Kc/)  # => ["abcdb", "c", "e"]
    ```

    As a side-effect this patch makes String#partition 2x faster when the
    pattern is a costly Regexp by performing Regexp search only once,
    which was unexpectedly done twice in the original implementation.

  Author: Jeremy Evans <code@jeremyevans.net>
  Date:   2020-07-24 06:10:04 +0900

    Improve performance of partial backtraces

    Previously, backtrace_each fully populated the rb_backtrace_t with all
    backtrace frames, even if caller only requested a partial backtrace
    (e.g. Kernel#caller_locations(1, 1)).  This changes backtrace_each to
    only add the requested frames to the rb_backtrace_t.

    To do this, backtrace_each needs to be passed the starting frame and
    number of frames values passed to Kernel#caller or #caller_locations.

    backtrace_each works from the top of the stack to the bottom, where the
    bottom is the current frame.  Due to how the location for cfuncs is
    tracked using the location of the previous iseq, we need to store an
    extra frame for the previous iseq if we are limiting the backtrace and
    final backtrace frame (the first one stored) would be a cfunc and not
    an iseq.

    To limit the amount of work in this case, while scanning until the start
    of the requested backtrace, for each iseq, store the cfp.  If the first
    backtrace frame we care about is a cfunc, use the stored cfp to find the
    related iseq.  Use a function pointer to handle the storage of the cfp
    in the iteration arg, and also store the location of the extra frame
    in the iteration arg.

    backtrace_each needs to return int instead of void in order to signal
    when a starting frame larger than backtrace size is given, as caller
    and caller_locations needs to return nil and not the empty array in
    these cases.

    To handle cases where a range is provided with a negative end, and the
    backtrace size is needed to calculate the result to pass to
    rb_range_beg_len, add a backtrace_size static function to calculate
    the size, which copies the logic from backtrace_each.

    As backtrace_each only adds the backtrace lines requested,
    backtrace_to_*_ary can be simplified to always operate on the entire
    backtrace.

    Previously, caller_locations(1,1) was about 6.2 times slower for an
    800 deep callstack compared to an empty callstack.  With this new
    approach, it is only 1.3 times slower. It will always be somewhat
    slower as it still needs to scan the cfps from the top of the stack
    until it finds the first requested backtrace frame.

    Fix corruption in ARGF.inplace

    Extension string stored in `ARGF.inplace` is created using an api
    designed for C string constants to create a Ruby string that
    points at another Ruby string. When the original string is swept,
    the extension string gets corrupted.

    Reproduction script (on MacOS):

    ```ruby
    #!/usr/bin/ruby -pi.bak

    BEGIN {
      GC.start(full_mark: true)
      arr = []
      1000000.times do |x|

    Test out fix for OpenSSL test flakiness

    `OpenSSL::TestX509Store#test_verify` has been failing intermittently on
    CI about once a day:
      - http://ci.rvm.jp/results/trunk-random2@phosphorus-docker/3121244
      - http://ci.rvm.jp/results/trunk-random1@phosphorus-docker/3117661
      - http://ci.rvm.jp/results/trunk-random1@phosphorus-docker/3111684

    According to the test:
     > OpenSSL uses time(2) while Time.now uses clock_gettime(CLOCK_REALTIME),
     > and there may be difference.

    This difference is could be the cause for the flaky failures. Let's see
    if giving the certificate more room solves the problem.

    In any case, I will revert this in a week. I think changes to these
    should go to https://github.com/ruby/openssl/?

    RubyVM::CEscape#rstring2cstr: do not escape '

    A single quote "is representable either by itself or by the escape
    sequence", according to ISO/IEC 9899 (checked all versions).  So this is
    not a bug fix.  But the generated output is a bit readable without
    backslashes.

    [ruby/net-http] Switch invalid server name format

    invalid_servername is not a valid name in an SSL request due to
    the use of the underscore, and LibreSSL 3.2.0 will raise an
    exception for this.  These tests are not testing the allowed
    characters in the server name, but how net/http handles cases where
    the server name provided does not match the IP address you are
    trying to connect to, so I think it's better to just modify the
    tests to use a correct format.

    While here, fix a typo in a test name, and use better code in the
    ensure block so the same test doesn't issue both a failure and an
    error.

     - http://ci.rvm.jp/results/trunk-test@ruby-sky1/2777695

    fix mark bit operation.

    To optimize the sweep phase, there is bit operation to set mark
    bits for out-of-range bits in the last bit_t.
    However, if there is no out-of-ragnge bits, it set all last bit_t
    as mark bits and it braek the assumption (unmarked objects will
    be swept).
    GC_DEBUG=1 makes sizeof(RVALUE)=64 on my machine and this condition
    happens.

    It took me one Saturday to debug this.

    This restores 3.0 behavior and goes back to not formatting executables
    by default on `gem update --system`. This is friendlier for jruby and
    doesn't really affect OS packagers.

    It was failed on Windows and I'm unsure why. Also, the check seems

    [rubygems/rubygems] Let more exceptions flow

    If any error happens while verifying a package entry, it doesn't mean
    that the package is corrupt. It could be a bug in rubygems, for example.
    This in fact happened in CI and the current error doesn't make it easy
    to troubleshoot the root cause, since it doesn't provide a backtrace.

    See
    https://github.com/rubygems/rubygems/pull/3807/checks?check_run_id=862526615.

    So I propose to let the exception happens. There was something useful
    about the previous message, which is the file entry where the error
    happened, so I'm keeping that information in a warning message.

    [rubygems/rubygems] Ignore internal frames in RubyGems' Kernel#warn

    * See https://github.com/oracle/truffleruby/issues/2046
    * `<internal:` is a common prefix also used by core Ruby files in CRuby.
    * test_no_kernel_require_in_*warn_with_uplevel already test this.
    * Unfortunately just skipping `<internal:` in the Ruby implementation
      is not enough, because RubyGems' #warn would not skip the
      `<internal:` require (TruffleRuby defines #require in Ruby),
      and the Ruby implementation's #warn would not skip
      RubyGems's #require. The #caller_locations(0) look like this:

      warnee.rb:1:in `<top (required)>' # where #warn is called
      <internal:core> core/kernel.rb:234:in `gem_original_require' # not skipped by RubyGems' warn, skipped by the Ruby impl
      rubygems/core_ext/kernel_require.rb:54:in `require' # not skipped by the Ruby impl's warn, what would be shown without this fix
      warn.rb:1:in `<main>' # what would be correct

      warn.rb is
      require "warnee"
      warnee.rb is
      puts caller_locations(0), nil
      warn "oops", uplevel: 1

    [rubygems/rubygems] Remove very old TODO note

    It was added 10 years ago on a "146 additions, 170 deletions" commit
    named "Deprecation removals and minor cleanup." that didn't explain much
    other than that.

    This TODO doesn't necessarily apply nowadays. I don't see how anyways.
    TODO notes, if useful at all, should include a clear explanation of what
    should be done either via the note itself or the commit message. This
    note doens't meet any of these.

    So I want to remove it because it distracts me every time I go through
    it.

    [rubygems/rubygems] Optimize Gem.already_loaded?

    Profiling a simple `ruby -e '1'` I see:

    ```
    ==================================
      Mode: wall(10)
      Samples: 3414 (55.10% miss rate)
      GC: 856 (25.07%)

           136   (4.0%)          59   (1.7%)     <top (required)>
          2312  (67.7%)          58   (1.7%)     <top (required)>
            57   (1.7%)          57   (1.7%)     RbConfig.expand
            81   (2.4%)          55   (1.6%)     Gem::Requirement.parse
           191   (5.6%)          51   (1.5%)     <top (required)>
           128   (3.7%)          47   (1.4%)     Gem::Requirement#initialize
            41   (1.2%)          41   (1.2%)     Gem.suffix_regexp
           229   (6.7%)          35   (1.0%)     <module:Gem>
           260   (7.6%)          34   (1.0%)     Kernel#require
    ```

    So clearly `Gem.already_loaded?` is a major hotspot.

    After this optimization, it's down to:
    ```
    ==================================
      Mode: wall(10)
      Samples: 2653 (58.21% miss rate)

           279  (10.5%)         279  (10.5%)     Gem.already_loaded?
           564  (21.3%)         106   (4.0%)     Gem.register_default_spec
            95   (3.6%)          80   (3.0%)     Gem::Specification#files
            72   (2.7%)          72   (2.7%)     Gem::BasicSpecification#internal_init
           129   (4.9%)          58   (2.2%)     <top (required)>
            53   (2.0%)          53   (2.0%)     RbConfig.expand
          1697  (64.0%)          52   (2.0%)     <top (required)>
            68   (2.6%)          49   (1.8%)     Gem::Requirement.parse
           183   (6.9%)          48   (1.8%)     <top (required)>
           112   (4.2%)          44   (1.7%)     Gem::Requirement#initialize
           220   (8.3%)          33   (1.2%)     <module:Gem>
           250   (9.4%)          32   (1.2%)     Kernel#require
    ```

    The idea is that the vast majority of the time `already_loaded?` won't match
    anything. So by first looking for candidate paths that `end_with?` the file we
    look for, we save `default_gem_load_paths.size` iterations and string concatenations.

    Use a linked list to eliminate imemo tmp bufs for managing local tables

    This patch changes local table memory to be managed by a linked list
    rather than via the garbage collector.  It reduces allocations from the
    GC and also fixes a use-after-free bug in the concurrent-with-sweep
    compactor I'm working on.

    Prevent SystemStackError when calling super in module with activated refinement

    Without this, if a refinement defines a method that calls super and
    includes a module with a module that calls super and has a activated
    refinement at the point super is called, the module method super call
    will end up calling back into the refinement method, creating a loop.

    Fixes [Bug #17007]

    Lazily insert origins on prepend to save memory

    98286e9850936e27e8ae5e4f20858cc9c13d2dde made it so that
    `Module#include` allocates an origin iclass on each use. Since `include`
    is widely used, the extra allocation can contribute significantly to
    memory usage.

    Instead of always allocating in anticipation of prepend, this change
    takes a different approach. The new setup inserts a origin iclass into
    the super chains of all the children of the module when prepend happens
    for the first time.

    rb_ensure_origin is made static again since now that adding an origin
    now means walking over all usages, we want to limit the number of places
    where we do it.

    Share the size for sigaltstack between configure.ac and signal.c

    configure.ac: Bump the size of sigaltstack

    The RubyVM uses C macro defines to feature detect whether
    `backtrace(2)` support is available, and if so it includes C level backtraces
    when the RubyVM itself crashes.

    But on my machine, C level backtraces from `vm_dump.c` didn't work when
    using a version of Ruby built on the machine, but worked fine when using a
    version of Ruby built on another machine and copied to my machine.

    The default autoconf test for backtraces uses a sigaltstack size that is
    too small, so the SIGSEGV signal handler itself causes a SIGSEGV).
    I noticed that signal.c uses a larger sigaltstack size:

    https://github.com/ruby/ruby/blob/v2_6_5/signal.c#L568

    The specific variables it looks at:

    - `HAVE_BACKTRACE`

      this is a macro defined by autoconf because there is a line in the
      configure script like `AC_CHECK_FUNCS(backtrace)` (see the autoconf
      docs for more).

    - `BROKEN_BACKTRACE`

      this comes from a custom program that Ruby's configure script runs to
      attempt to figure out whether actually using backtrace(2) in a real
      program works. You can see the autoconf program here.

      <https://github.com/ruby/ruby/blob/v2_6_5/configure.ac#L2817-L2863>

    It uses sigaltstack and SA_ONSTACK to create a separate stack for
    handling signals.

    The problem was: SIGSTKSZ (which comes from a system header!) was not
    suggesting a large enough stack size. When checking on an Ubuntu 16.04
    box, we found that SIGSTKSZ was 8192 and MINSIGSTKSZ was 2048.

    > How about lexer = Ripper::Lexer.new(";\n#{code}", nil, 0)?
    > Encoding pragma is effective only at the beginning.
    > And the semicolon and newline will be skipped because the position is before
    > the initial pos.

    I employ the way.

    [DOC] time.c document updated.

    * fraction -> subsecond
      for consistency with method name

    * The sentence,
      "A non-portable feature allows the offset to be negative on some systems.",
      is removed.
      Time before 1970 should work portably now.
      If localtime() doesn't work before 1970,
      Ruby should extrapolate it.

    * Time::new -> Time.new
      "::" for method call is not common notation now.

    * Time#to_i truncates subsecond

    * Time#to_f approximates a value in Time object

    * Time#to_r
      The sentence,
      "You can use this method to convert _time_ to another Epoch.",
      is removed.
      It is not clear because no actual example of "another Epoch" is given.

    * Time#usec truncates fraction of microseconds.

    * Time#nsec truncates fraction of nanoseconds.

    * describe Time#inspect shows subsecond since Ruby 2.7.0.

    [ruby/csv] Add `undef: :replace` for `CSV.open` (#129)

    This PR adds `undef: :replace` option for `CSV.open`.

    `File.open` has `undef: :replace` option, but `CSV.open` does not.
    It would be convenient if `CSV.open` could have a shortcut by having
    `undef: :replace` option.

    Previously, calling `dup` on a `CSV::Row` object yielded an object whose
    copy was too shallow. Changing the clone's fields would also change the
    fields on the source. This change makes the clone more distinct from the
    source, so that changes can be made to its fields without affecting the
    source.

    Special case Range#max for integer beginning and Float::Infinity end

    Popular Ruby libraries such as Rails and Rubocop relying on the
    previous behavior, even though it is technically a bug. The
    correct behavior is probably raising RangeError, since that is what
    an endless range raises.

    ruby_core has an 'ast.rb' file that gets in the

    Also, slightly change the spec name from "run" to
    "runs" and change the last assertion, it's cleaner
    to check empty error.

    [rubygems/rubygems] Fix RuboCop offenses

    These offenses appear when you create a gem with

    Initially, there were around 45 offenses detected,

    Fix Range#{max,minmax} for range with integer beginning and non-integer end

    Previously, for inclusive ranges, the max would show up as the
    end of the range, even though the end was not an integer and would
    not be the maximum value.  For exclusive ranges, max/minmax would
    previously raise a TypeError, even though it is possible to get the
    correct maximum.

    This change to max/minmax also uncovered a similar error in cover?,
    which calls max in certain cases, so adjust the code there so that
    cover? still works as expected.

    Fixes [Bug #17017]

    Expand heap pages to be exactly 16kb

    This commit expands heap pages to be exactly 16KiB and eliminates the
    `REQUIRED_SIZE_BY_MALLOC` constant.

    I believe the goal of `REQUIRED_SIZE_BY_MALLOC` was to make the heap
    pages consume some multiple of OS page size.  16KiB is convenient because
    OS page size is typically 4KiB, so one Ruby page is four OS pages.

    Do not guess how malloc works
    =============================

    We should not try to guess how `malloc` works and instead request (and
    use) four OS pages.

    Here is my reasoning:

    1. Not all mallocs will store metadata in the same region as user requested
    memory.  jemalloc specifically states[1]:

    > Information about the states of the runs is stored as a page map at the beginning of each chunk.

    2. We're using `posix_memalign` to request memory.  This means that the
       first address must be divisible by the alignment.  Our allocation is
       page aligned, so if malloc is storing metadata *before* the page,
       then we've already crossed page boundaries.

    3. Some allocators like glibc will use the memory at the end of the
       page.  I am able to demonstrate that glibc will return pointers
       within the page boundary that contains `heap_page_body`[2].  We
       *expected* the allocation to look like this:

    ![Expected alignment](https://user-images.githubusercontent.com/3124/85803661-8a81d600-b6fc-11ea-8cb6-7dbdb434a43b.png)

       But since `heap_page` is allocated immediately after
       `heap_page_body`[3], instead the layout looks like this:

    ![Actual alignment](https://user-images.githubusercontent.com/3124/85803714-a1c0c380-b6fc-11ea-8c17-8b37369e17ee.png)

       This is not optimal because `heap_page` gets allocated immediately
       after `heap_page_body`.  We frequently write to `heap_page`, so the
       bottom OS page of `heap_page_body` is very likely to be copied.

    One more object per page
    ========================

    In jemalloc, allocation requests are rounded to the nearest boundary,
    which in this case is 16KiB[4], so `REQUIRED_SIZE_BY_MALLOC` space is
    just wasted on jemalloc.

    On glibc, the space is not wasted, but instead it is very likely to
    cause page faults.

    Instead of wasting space or causing page faults, lets just use the space
    to store one more Ruby object.  Using the space to store one more Ruby
    object will prevent page faults, stop wasting space, decrease memory
    usage, decrease GC time, etc.

  Date:   2020-07-04 11:56:07 +0900

    Fix non-numeric exclusive Range#minmax bug

    The implementation of Range#minmax added in d5c60214c45 causes the
    following incorrect behaviour:

      ('a'...'c').minmax => ["a", ["a", "b"]]

    instead of

      ('a'...'c').minmax => ["a", "b"]

    This is because the C implementation of Range#minmax (range_minmax)
    directly delegates to the C implementation of Range#min (range_min) and
    Range#max (range_max), without changing the execution context.

    Range#max's C implementation (range_max), when given a non-numeric
    exclusive range, delegates to super, which is meant to call
    Enumerable#max. However, because range_max is called directly by
    range_minmax, super calls Enumerable#minmax instead, causing the
    incorrect nesting.

    Perhaps it is possible to change the execution context in an optimized
    manner, but the simplest solution seems to be to just explicitly
    delegate from Range#minmax to Range#min and Range#max.

    support all locals for cexpr!, cstmt!

    Primitve.cexpr! and .cstmt! can access Ruby's parameter and
    *local variables* (note that local parameters are also local
    variables). However recent changes only allow to access
    parameters. This patch fix it.

    For example, the following code can work:

    def foo a, b, k: :kw, **kwrest
      c = a + b
      d = k
      e = kwrest
      p Primitive.cstmt!(%q(rb_p(rb_ary_new_from_args(5, a, b, c, d, e));

    Rewrite Kernel#tap with Ruby (#3281)

    * Rewrite Kernel#tap with Ruby

    This was good for VM too, but of course my intention is to unblock JIT's inlining of a block over yield
    (inlining invokeyield has not been committed though).

    * Fix test_settracefunc

    About the :tap deletions, the :tap events are actually traced (we already have a TracePoint test for builtin methods),
    but it's filtered out by tp.path == "xyzzy" (it became "<internal:kernel>"). We could trace tp.path == "<internal:kernel>"
    cases too, but the lineno is impacted by kernel.rb changes and I didn't want to make it fragile for kernel.rb lineno changes.

    Use ID instead of GENTRY for gvars. (#3278)

    Use ID instead of GENTRY for gvars.

    Global variables are compiled into GENTRY (a pointer to struct
    rb_global_entry). This patch replace this GENTRY to ID and
    make the code simple.

    We need to search GENTRY from ID every time (st_lookup), so
    additional overhead will be introduced.
    However, the performance of accessing global variables is not
    important now a day and this simplicity helps Ractor development.

    RUBY_DEBUG_LOG: Logging debug information mechanism (#3279)

    * RUBY_DEBUG_LOG: Logging debug information mechanism

    This feature provides a mechanism to store logging information
    to a file, stderr or memory space with simple macros.

    The following information will be stored.
      * (1) __FILE__, __LINE__ in C
      * (2) __FILE__, __LINE__ in Ruby
      * (3) __func__ in C (message title)
      * (4) given string with sprintf format
      * (5) Thread number (if multiple threads are running)

    This feature is enabled only USE_RUBY_DEBUG_LOG is enabled.
    Release version should not enable it.

    Running with the `RUBY_DEBUG_LOG` environment variable enables
    this feature.

      # logging into a file
      RUBY_DEBUG_LOG=/path/to/file STDERR

      # logging into STDERR
      RUBY_DEBUG_LOG=stderr

      # logging into memory space (check with a debugger)
      # It will help if the timing is important.
      RUBY_DEBUG_LOG=mem

    RUBY_DEBUG_LOG_FILTER environment variable can specify the filter string.
    If "(3) __func__ in C (message title)" contains the specified string, the
    information will be stored (example: RUBY_DEBUG_LOG_FILTER=str will enable
    only on str related information).

    In a MRI source code, you can use the following macros:
      * RUBY_DEBUG_LOG(fmt, ...): Above (1) to (4) will be logged.
      * RUBY_DEBUG_LOG2(file, line, fmt, ...):
        Same as RUBY_DEBUG_LOG(), but (1) will be replaced with given file, line.

    rb_class_modify_check: add UNREACHABLE

    (I was not aware of this because I use clang, but) it seems gcc cannot
    detect reachablility of this point.  It renders an unused variable
    warning, which is a false positive.  Let us suppress the compiler.

    Not every compilers understand that rb_raise does not return.  When a
    function does not end with a return statement, such compilers can issue
    warnings.  We would better tell them about reachabilities.

    Decide JIT-ed insn based on cached cfunc

    for opt_* insns.

    opt_eq handles rb_obj_equal inside opt_eq, and all other cfunc is
    handled by opt_send_without_block. Therefore we can't decide which insn
    should be generated by checking whether it's cfunc cc or not.

    fix return event and opt_invokebuiltin_delegate_leave (#3256)

    If :return event is specified for a opt_invokebuiltin_delegate_leave
    and leave combination, the instructions should be
      opt_invokebuiltin_delegate
      trace_return
    instructions. To make it, opt_invokebuiltin_delegate_leave
    instruction will be changed to opt_invokebuiltin_delegate even if
    it is not an event target instruction.

    Avoid generating opt_send with cfunc cc with JIT

    only for opt_nil_p and opt_not.

    While vm_method_cfunc_is is used for opt_eq too, many fast paths of it
    don't call it. So if it's populated, it should generate opt_send,
    regardless of cfunc or not. And again, opt_neq isn't relevant due to the
    difference in operands.
    So opt_nil_p and opt_not are the only variants using vm_method_cfunc_is
    like they use.

    Convert RMoved to a doubly linked list

    This commit converts RMoved slots to a doubly linked list. I want to
    convert this to a doubly linked list because the read barrier (currently
    in development) must remove nodes from the moved list sometimes.
    Removing nodes from the list is much easier if the list is doubly
    linked.  In addition, we can reuse the list manipulation routines.

    [ruby/date] Fix cannot load complex into simple error when loading marshal dump (Fixes #20)

    This problem exists because Marshal.load calls Date.allocate, which
    uses a SimpleDateData.  There doesn't seem to be any support for
    taking an existing Date instance and converting it from SimpleDateData
    to ComplexDateData.  Work around this issue by making Date.allocate
    use a ComplexDateData.  This causes problems in Date#initialize,
    so remove the Date#initialize method (keeping the date_initialize
    function, used internally for Date.civil). Alias Date.new to
    Date.civil, since they do the same thing.

    compile.c: Improve branch coverage instrumentation [Bug #16967]

    Formerly, branch coverage measurement counters are generated for each
    compilation traverse of the AST.  However, ensure clause node is
    traversed twice; one is for normal-exit case (the resulted bytecode is
    embedded in its outer scope), and the other is for exceptional case (the
    resulted bytecode is used in catch table).  Two branch coverage counters
    are generated for the two cases, but it is not desired.

    This changeset revamps the internal representation of branch coverage
    measurement.  Branch coverage counters are generated only at the first
    visit of a branch node.  Visiting the same node reuses the
    already-generated counter, so double counting is avoided.

    but procs created from the same block are treated as equal, even
    when the lazy proc allocation optimization is used.

    Implements [Feature #14267]

    Use filesystem encoding as FileHandler's encoding

    instead of `@root.encoding`.
    And fallback to ASCII-8BIT when filesystem encoding is US-ASCII.

    When `@root.encoding` is not compatible filesystem encoding,
    `Encoding::CompatibilityError` raised at `webrick/httpservlet/filehandler.rb:341`.
    So `DocumentRoot` must be compatible with filesystem encoding.

    Doing so modifies the class's method table, but not in a way that should

    Raise RuntimeError for class variable overtaken in nonverbose mode

    900e83b50115afda3f79712310e4cb95e4508972 changed from a warning
    to an error in this case, but the warning was only issued in
    verbose mode, and therefore the error was only raised in verbose
    mode.  That was not intentional, verbose mode should only change
    whether warnings are emitted, not other behavior.  This issues
    the RuntimeError in all cases.

    This change broke a couple tests, as the tests actually issued
    the warning and therefore now raise an error.  This wasn't caught
    earlier as test_variable suppressed the warning in this case,
    effectively setting $VERBOSE = false around the code that warned.
    basictest isn't run in verbose mode and therefore didn't expose
    the issue previously. Fix these tests.

    Dup splat array in certain cases where there is a block argument

    This makes:

    ```ruby
      args = [1, 2, -> {}]; foo(*args, &args.pop)
    ```

    call `foo` with 1, 2, and the lambda, in addition to passing the
    lambda as a block.  This is different from the previous behavior,
    which passed the lambda as a block but not as a regular argument,
    which goes against the expected left-to-right evaluation order.

    This is how Ruby already compiled arguments if using leading
    arguments, trailing arguments, or keywords in the same call.

    This works by disabling the optimization that skipped duplicating
    the array during the splat (splatarray instruction argument
    switches from false to true).  In the above example, the splat
    call duplicates the array.  I've tested and cases where a
    local variable or symbol are used do not duplicate the array,
    so I don't expect this to decrease the performance of most Ruby
    programs.  However, programs such as:

    ```ruby
      foo(*args, &bar)
    ```

    could see a decrease in performance, if `bar` is a method call
    and not a local variable.

    This is not a perfect solution, there are ways to get around
    this:

    ```ruby
      args = Struct.new(:a).new([:x, :y])
      def args.to_a; a; end
      def args.to_proc; a.pop; ->{}; end
      foo(*args, &args)
      # calls foo with 1 argument (:x)
      # not 2 arguments (:x and :y)
    ```

    A perfect solution would require completely disabling the
    optimization.

    Make Module#prepend affect the iclasses of the module

    3556a834a2847e52162d1d3302d4c64390df1694 added support for
    Module#include to affect the iclasses of the module.  It didn't add
    support for Module#prepend because there were bugs in the object model
    and GC at the time that prevented it.  Those problems have been
    addressed in ad729a1d11c6c57efd2e92803b4e937db0f75252 and
    98286e9850936e27e8ae5e4f20858cc9c13d2dde, and now adding support for
    it is straightforward and does not break any tests or specs.

    [rubygems/rubygems] Disable parallel installation by default on Windows

    Since we enabled parallel installation by default, we've fixed all the
    issues related to it that have come up, except for a Windows issue that
    we haven't yet figured out. This issue is hit by our specs on a daily
    basis and there's no reason to believe that it won't be hit by end users
    in a similar way.

    So, both to stop the testing flakyness and to prevent regressions in the
    default behavior on Windows, I'd rather leave the default as it was
    before on Windows for now.

    [rubygems/rubygems] Make sure to pass URI's to `:git`

    Passing paths should work in most cases, but on Windows the driver
    letter is interpreted as the scheme and causes some case mismatches
    because

    ```
    irb> URI.parse("E:").to_s
    => "e:"
    ```

    We fix this by passing file URI's instead.

    Ship default .rubocop.yml

    Currently, there is no `.rubocop.yml` shipped by default.
    So when a user runs `rubocop` after creating a new gem via
    `bundle gem foo`, it throws a bunch of offenses.

    With the default `.rubocop.yml` present, the number of those
    offenses significantly reduce by 25.

    Rename hidden templates

    Because they don't play nice with ruby-core's gitignore and cause issues
    with ruby-core integration.

    Also, because it's consistent with other templates such as `gitignore.tt`.

    [rubygems/rubygems] Fix a couple of specs that were loading an incorrect bundler

    We have a check on an `at_exit` hook that checks that system bundler is

    these cases, but in a silent way because the errors were being swallowed.

    This commit changes these specs to make sure they load the right
    bundler.

    [rubygems/rubygems] Change spec to do the right thing on bundler 3

    On bundler 3, the `--deployment` flag doesn't exist, so the `bundle
    install --deployment` command was failing silently and the spec was
    verifying a different scenario.

    Change the spec to work the same regardless of bundler's major version.

    Also, from the spec description it was not apparently that a specific
    case involving deployment mode was being tested, so I reworded it to
    make it more apparent.

    [rubygems/rubygems] Fix some sudo specs to do the right thing on bundler 3

    On bundler 3, where the default install path is `.bundle`, these specs
    were trying to change permissions of the
    `.bundle/ruby/<ruby_abi_version>` folder, which didn't exist yet,so the
    permission changing command was failing and the spec was not testing the
    right thing.

    Change the specs so that the permissions are correctly changed, by first
    configuring the local path to be `.bundle` (which creates the `.bundle`
    folder), and then changing permissions of the `.bundle` folder
    explicitly, which exists already.

    [rubygems/rubygems] Fix spec to test the right thing on bundler 3

    Bundler 3 installs by default to `.bundle`. That means that, because the
    `bar` gem was not previously available at this location but as a system
    gem, the initial `bundle install` was silently failing. As a
    consequence, the spec was not testing the exact scenario it meant to
    test.

    This spec is specifically testing for the case where there's no

    `bundle install` command is silently failing. Remove the `bundle
    install` to reduce confusion.

    [rubygems/rubygems] Fix unintended Gemfile installation

    This command is failing because of the same reason that the subsequent

    here deviates the `bundle exec` focus from the test and is unnecessary:
    all we need is a `Gemfile` that will trigger the `bundle exec`, so let's
    create and avoid the extra command.

    [rubygems/rubygems] Remove broken test

    It turns out that this test is checking essentially nothing useful. The
    paperclip gem doesn't exist in our setup, so initial install is failing
    and the test is only checking that calling `bundle check` 3 times on a
    broken setup always returns the same thing.

    I went to the history of this test:

    * https://github.com/rubygems/bundler/commit/105654a31e07e9b0a198f1a5a5ec94e365854edf

    And have finally decided to remove it since I'm not sure changing it to
    something else will lead to testing something useful and not already
    tested.

    [rubygems/rubygems] Fix silently broken spec

    This spec was broken. The second `bundle install` was silently failing.
    This means that the spec was actually checking an scenario completely
    different from the one that was supposed to be tested. And also a very
    dummy one: that running `bundle cache` twice doesn't cache a completely
    unrelated gem.

    install`'ing a Genfile with only that dependency like the spec the

    [rubygems/rubygems] Fix `only_update_to_newer_versions` regression

    The `only_update_to_newer_versions` feature flag will enable some new
    behaviour in bundler 3 (or maybe earlier if we decide to consider it a
    bug fix) that prevents `bundle update` from unexpectedly downgrading
    direct dependencies.

    This seems reasonable, but the current implementation is adding
    additional requirements for all locked dependencies, not only from the
    ones in the `Gemfile`. That causes some situations where the `Gemfile`
    is edited and will resolve to older versions to start failing.

    This commit fixes the problem by making sure extra requirements are
    added exclusively for direct dependencies in the `Gemfile`, not for all
    direct dependencies in the lock file.

    ```

    These CI environments use very long TMPDIR for some reason.
    The test case creates a directory in TMPDIR and attempts to add a
    symbolic link to the path into a tarball.  However, tar format limits
    the maximum length up to 99, so the path is truncated.
    This truncation makes the path check of `Gem::Package#install_location`
    pass through, and then the check of `#mkdir_p_safe` raises an error.
    The error message is slightly different from the expected value, so the
    test fails.

    I'm unsure what to do, so I tentatively skip the test when TMPDIR is
    long.  I'll create a ticket into rubygems bug tracker.

    Make sure to only reset "dummy" $LOADED_FEATURES

    Namely, those generated under `/tmp`.

    The previous approach was brittle and broken in the case of ruby-core,
    because under that setup, the current folder is in the original
    `$LOAD_PATH`, and dummy features are created under `./tmp`, so they were
    failing to be reset.

    Make sure tmp folder exists before calling `Dir.tmpdir`

    This was guaranteed by our gitignore setup where a `tmp/` folder is
    always present right after cloning the repository, but was not

    This alternative approach should always work.

    rb_method_name_error: delete unused code

    If you look at the code flow (break -> goto), this assignment never
    makes any sense.  Should just remove.

    I _guess_ this behaviour is unintended.  Original code at commit
    4dc1a2180946ab793adee5eb235fc4ee8fa4cefe did something.  It might be
    the code flow that is buggy.  However rubyspec already includes this
    particular edge case at ruby/core/module/undef_method_spec.rb.  I don't
    think we can change the way it is any longer.

    Fix ruby-head failing tests

    In `ruby-head` (where system rubygems already has the `XDG` standard
    implementation), some tests currently depend on the presence of a
    `~/.gem` folder in the home of the user that runs the tests. If that
    file is present, tests pass, otherwise they don't.

    For example, the following passes if you have a `~/.gem` folder but
    fails otherwise with:

    ```
    $ rake TESTOPTS="--name=/TestGemCommandsGenerateIndexCommand#test_execute$\|TestGemCommandsUpdateCommand#test_execute_user_install/ -v"
    Run options: "--name=/TestGemCommandsGenerateIndexCommand#test_execute$|TestGemCommandsUpdateCommand#test_execute_user_install/" -v --seed 17318

    # Running:

    TestGemCommandsGenerateIndexCommand#test_execute = 0.02 s = .
    TestGemCommandsUpdateCommand#test_execute_user_install = /rubygems/test/rubygems/test_gem_commands_update_command.rb:412: warning: instance variable @user_install not initialized
    0.04 s = F

    Finished in 0.095337s, 20.9783 runs/s, 20.9783 assertions/s.

      1) Failure:
    TestGemCommandsUpdateCommand#test_execute_user_install [/rubygems/test/rubygems/test_gem_commands_update_command.rb:414]:
    user_install must be set on the installer

    2 runs, 2 assertions, 1 failures, 0 errors, 0 skips
    rake aborted!
    Command failed with status (1)

    Tasks: TOP => default => test
    (See full trace by running task with --trace)

    ```

    This is because the very initial `require` of the default `did_you_mean`
    gem that ruby does on startup runs _before_  the global `setup` hook of
    our tests run. During this require `Gem.data_home` and its value is
    memoized to a path in the real users home (not the fake user's home that
    our tests setup, since that code hasn't run yet). Then that memoized
    value is used when looking for the default folders to look for gems, and
    since there's no `~/.gem` folder, its value is actually used as part of
    the `Gem.user_dir` folder in `Gem::Specification.dirs` (this is how
    we've approached backwards compatibility for the `XDG` feature). That
    means dummy test gems with the `--user-install` flag are installed to
    global, real locations and everything is messed up.

    This commit fixes the issue by resetting the `Gem.data_home` value in
    case it has already been memoized.

    tool/lib/minitest/unit.rb: Reproducible shuffle of test suites

    ... based on CRC32 of names of the test suites.

    Formerly, `make test-all` randomized the order of the test suites by
    using `Array#shuffle`.  It also shows `--seed N` to reproduce the order,
    but it was not reproducible when a suite set is different.

    This change sorts the suites by CRC32 hash of the suite names with a
    salt generated by the seed.

    Fix most exec specs

    The `gem_command` helper was failing to require `support/hax.rb`, which
    takes care of making sure rubygems actually picks up the right `ruby`
    executable under ruby-core setup (`ENV["RUBY"]`). This caused binstubs
    to be generated with a wrong shebang, and that caused `bundle exec` to
    not work. The error message was pretty confusing though due to
    https://bugs.ruby-lang.org/issues/16952.

    [ruby/fileutils] Fix #install with "X" mode option

    `FileUtils#install` methed raises an unexpected `TypeError`, when
    called with `mode:` option which has `"X"`.

    ```

            from -e:1:in `<main>'
    ```

    In spite of that `symbolic_modes_to_i` considers the `File::Stat`
    `path` case at the beginning, in `"X"` case, `path` is passed to
    `FileTest.directory?` method which requires a `String`.  In such
    case, the mode in `path` should be examined instead.

    Prohibit setting class variable on frozen module through inheritance

    Setting class varibles goes through the ancestor list which can
    contain iclasses. Iclasses share a lot of information with the
    module they are made from, but not the frozen status.

    Check the frozen status of the module instead of the iclass.

    vm_call_method: avoid marking on-stack object

    This callcache is on stack, must not be GCed.  However its contents are
    copied from other materials, which can be an ordinal object.  Should
    set a flag to make sure it is properly skipped by the GC.

    Work around infinite loop when overriding method visibility in prepended module (#3201)

    For ZSUPER methods with no defined class for the method entry, start the next lookup at the superclass of the origin class of the method owner, instead of the superclass of the method owner.

    Revert "Combine sweeping and moving"

    This reverts commit 02b216e5a70235f42f537e895d6f1afd05d8916a.
    This reverts commit 9b8825b6f94696c9659f93f5da9bf02644625f67.

    I found that combining sweep and move is not safe.  I don't think that
    we can do compaction concurrently with _anything_ unless there is a read
    barrier installed.

    Here is a simple example.  A class object is freed, and during it's free
    step, it tries to remove itself from its parent's subclass list.
    However, during the sweep step, the parent class was moved and the
    "currently being freed" class didn't have references updated yet.  So we
    get a segv like this:

    rb_vm_search_method_slowpath: skip vm_empty_cc

    Now that vm_empty_cc is statically allocated outside of the object
    space.  It shall not be GCed.  Here, because vm_search_cc can return
    that.  Must not be blindly passed to RB_OBJ_WRITE, unless assertions
    fail on RGENGC_CHECK_MODE, like this:

    vm_ci_markable: added

    CIs are created on-the-fly, which increases GC pressure.  However they
    include no references to other objects, and those on-the-fly CIs tend to
    be short lived.  Why not skip allocation of them.  In doing so we need
    to add a flag denotes the CI object does not reside inside of objspace.

    The idFWD_KWREST sections may be wrong. However, the existing
    idFWD_KWREST sections for ... without leading arguments are already
    broken.

    [ruby/psych] Remove unnecessary version guard from versions.rb

    Removing it triggers the following warnings when running `bundle` under
    jruby from the root of the `psych` repo prints the following warnings:

    ```
    /path/to/jruby-9.2.9.0/lib/ruby/gems/shared/gems/psych-3.1.0-java/lib/psych/versions.rb:7: warning: already initialized constant VERSION
    /path/to//jruby-9.2.9.0/lib/ruby/gems/shared/gems/psych-3.1.0-java/lib/psych/versions.rb:10: warning: already initialized constant DEFAULT_SNAKEYAML_VERSION
    ```

    This is because bundler loads the versions file relatively from the
    local gemspec, and then internally loads the psych gem, causing the
    redefinition warnings.

    Instead, we modify the $LOAD_PATH so that when working locally on the
    `psych` repo, the local version of `psych` gets used.

    Coverage report generated for Unit Tests to /home/deivid/Code/rubygems/coverage. 8080 / 8978 LOC (90.0%) covered.
    ```

    The reason is that, although these tests wrap the
    `Rake.application["package"].invoke` with a `capture_io` block, the rake
    application initialization happens outside of this block, and a copy of
    `$stdout` is saved in there, and that's where the task prints. So the
    `capture_io` `$stdout` and `$stderr` dance is not effective.

    To fix, we move the `Rake` application initialization inside the
    `capture_io` block.

    [rubygems/rubygems] Fix `$LOADED_FEATURES` cache sometimes not respected

    In the cases where the initial manually `-I` path resolution succeeded,
    we were passing a full path to the original require effectively skipping
    the `$LOADED_FEATURES` cache. With this change, we _only_ do the
    resolution when a matching requirable path is found in a default gem. In
    that case, we skip activation of the default gem if we detect that the
    required file will be picked up for a `-I` path.

            /home/deivid/.rbenv/versions/2.7.1/bin/bundle

    ```

    This is because the `$LOAD_PATH` entry added by `setup.rb` is relatively
    and when the offending require happens, we're installing `bundler` and
    have switched folders to `bundler/`. So the require fallsback to the
    system rubygems.

    To avoid that, add an absolute path to the `$LOAD_PATH`.

    On jruby, somehow the $LOAD_PATH is manipulated so that we end up
    requiring stuff inside the built package even if we have specified the
    `-I` flag, so we get redefinition warnings anyways.

    I'm not sure about the root cause, but relative requiring fixes it, and
    it's faster anyways.

    [rubygems/rubygems] Delay `fileutils` loading to fix some warnings

    If the following conditions are met:

    * You have a default version of fileutils and a higher version of
    fileutils installed as a regular gem. This case is common on ruby 2.6.

    * You use a bundler generated binstub on a gem setup with a `Gemfile`
    using the `gemspec` DSL.

    Then `fileutils` redefinition warnings happen because of the following:

    The gist of a bundler generated binstub is:

    ```ruby
    require "bundler/setup"
    load Gem.bin_path("rake", "rake")
    ```

    First configure bundler, then load the requested gem.

    When `require "bundler/setup"` is called under the previously mentioned
    setup, `ext_conf_builder.rb` ends up being required because of the new
    validation that gemspecs with rake extensions depend on `rake`. And that
    loads the latest version of `fileutils` because of using "rubygems
    monkeypatched require" that auto-chooses the latest version of default
    gems.

    After that, when `Gem.bin_path` gets called, `ext_conf_builder.rb` gets
    required again, but this time already using "bundler's unmonkeypatched
    require" which means the default version is chosen and thus the
    redefinition warning happens.

    The solution as usual is to lazily load `fileutils`.

    Re-record all cassettes

    I had to pin `redis-namespace` in our spec to 1.6.0 because on ruby
    2.3.0 the spec no longer resolved to that version, so the cached `.gem`
    file was missing there.

commit 0fb2a7fa1cd9348fba04e15bbc115776f4cc6d0a

    Fix `bin/rake spec:realworld:record`

    Previously it was failing and not recording. Also, the
    `BUNDLER_SPEC_FORCE_RECORD` environment variable was forcing every
    request to be recorded, including duplicated requests to the same
    endpoint. That meant the recorded `versions` file would be incorrect
    because it would contain the result of the last request, which would be
    `304 NOT MODIFIED`.

    So, to rerecord, delete cassettes and let them be recorded when needed.

    [rubygems/rubygems] Support running specs against a tarball

    When bundler specs are run from a ruby tarball (ruby-core does this),
    there's no git folder, so `git ls-files` fails.

    Support this case by making specs rely on the list of files from the
    bundler gemspec instead, and invert the spec that makes sure we ship the
    right set of files.

    As per the other quality specs, skip them in this case.

    Ensure origins for all included, prepended, and refined modules

    This fixes various issues when a module is included in or prepended
    to a module or class, and then refined, or refined and then included
    or prepended to a module or class.

    Implement by renaming ensure_origin to rb_ensure_origin, making it
    non-static, and calling it when refining a module.

    Fix Module#initialize_copy to handle origins correctly.  Previously,
    Module#initialize_copy did not handle origins correctly.  For example,
    this code:

    ```ruby
    module B; end
    class A
      def b; 2 end
      prepend B
    end
    a = A.dup.new
    class A
      def b; 1 end
    end
    p a.b
    ```

    Printed 1 instead of 2.  This is because the super chain for
    a.singleton_class was:

    ```
    a.singleton_class
    A.dup
    B(iclass)
    B(iclass origin)
    A(origin) # not A.dup(origin)
    ```

    The B iclasses would not be modified, so the includer entry would be
    still be set to A and not A.dup.

    This modifies things so that if the class/module has an origin,
    all iclasses between the class/module and the origin are duplicated
    and have the correct includer entry set, and the correct origin
    is created.

    This requires other changes to make sure all tests still pass:

    * rb_undef_methods_from doesn't automatically handle classes with
      origins, so pass it the origin for Comparable when undefing
      methods in Complex. This fixed a failure in the Complex tests.

    * When adding a method, the method cache was not cleared
      correctly if klass has an origin.  Clear the method cache for
      the klass before switching to the origin of klass.  This fixed
      failures in the autoload tests related to overridding require,
      without breaking the optimization tests.  Also clear the method
      cache for both the module and origin when removing a method.

    * Module#include? is fixed to skip origin iclasses.

    * Refinements are fixed to use the origin class of the module that
      has an origin.

    * RCLASS_REFINED_BY_ANY is removed as it was only used in a single
      place and is no longer needed.

    * Marshal#dump is fixed to skip iclass origins.

    * rb_method_entry_make is fixed to handled overridden optimized
      methods for modules that have origins.

    Fixes [Bug #16852]

    vm_call_symbol: check stack overflow

    VM stack could overflow here.  The condition is when a symbol is passed
    to a block-taking method via &variable, and that symbol has never been
    used for actual method names (thus yielding that results in calling
    method_missing), and the VM stack is full (no single word left).  This
    is a once-in-a-blue-moon event.  Yet there is a very tiny room of stack
    overflow.  We need to check that.

    vm_invoke_symbol_block: reduce MEMCPY

    This commit changes the number of calls of MEMCPY from...

                               | send  | &:sym
      -------------------------|-------|-------
       Symbol already interned | once  | twice
       Symbol not pinned yet   | none  | once

    to:

                               | send  | &:sym
      -------------------------|-------|-------
       Symbol already interned | once  | none
       Symbol not pinned yet   | twice | once

    So it sacrifices exceptional situation for normal path.

    vm_invoke_symbol_block: call vm_call_opt_send

    Symbol#to_proc and Object#send are closely related each other.  Why not
    share their implementations.  By doing so we can skip recursive call of

    vm_invoke_block: insertion of unused args

    This makes it possible for vm_invoke_block to pass its passed arguments
    verbatimly to calling functions.  Because they are tail-called the
    function calls can be strength-recuced into indirect jumps, which is a
    huge win.

    vm_insnhelper.c: merge opt_eq_func / opt_eql_func

    These two function were almost identical, except in case of
    T_STRING/T_FLOAT. Why not merge them into one, and let the difference be
    handled in normal method calls (slowpath).  This does not improve
    runtime performance for me, but at least reduces for instance rb_eql_opt
    from 653 bytes to 86 bytes on my machine, according to nm(1).

    Combine sweeping and moving

    This commit combines the sweep step with moving objects.  With this
    commit, we can do:

    ```ruby
    GC.start(compact: true)
    ```

    This code will do the following 3 steps:

    1. Fully mark the heap
    2. Sweep + Move objects
    3. Update references

    By default, this will compact in order that heap pages are allocated.
    In other words, objects will be packed towards older heap pages (as
    opposed to heap pages with more pinned objects like `GC.compact` does).

    spec: add wsl guard

    WSL 2 is officially released.  It uses Linux kernel, so almost all specs
    for Linux work on WSL, except one: gethostbyaddr.  I guess network
    resolution in WSL is based on Windows, so the behavior seems a bit
    different from normal Linux.

    This change adds `platform_is_not :wsl` guard, and guards out the test
    in question.

    RUBY_ASSERT_NOASSUME

    If __builtin_assume() is enables and RUBY_DEBUG=0, RUBY_ASSERT(expr)
    will be compiled to __builtin_assume(expr) and compiler can assume
    expr is true and apply aggressive optimizations. However we observed
    doubtful behavior because of compiler optimizations, we introduce
    new macro RUBY_ASSERT_NOASSUME to disable __builtin_assume().
    With this macro, we can try without __builtin_assume().

    Remove Ruby <2.2 support from tool/lib/vcs.rb

    BASERUBY now requires at least Ruby 2.2, so there is no point
    trying to support older ruby versions here.

commit 9a3371be8f5274d1dca64b93c7b9a379e32ea2f5

    Check that BASERUBY is at least Ruby 2.2 in configure

    BASERUBY needs to be at least Ruby 2.2 since
    46acd0075d80c2f886498f089fde1e9d795d50c4.

    I think it's better to explicitly fail early as soon as BASERUBY
    is used in this case, versus trying to debug later failures.

    This modifies things to check both implicitly use of ruby in the
    PATH as BASERUBY, and explicitly specified older versions of ruby
    when using --with-baseruby.

    Fixes [Bug #16668]

       - c74a3b21f59:: `cygwin-$(RUBY_INSTALL_NAME)-$(MAJOR).$(MINOR).dll`

    2. And then renamed to be net distribution compliant.

       - 6f059f33ef1:: `cyg$(RUBY_SO_NAME)$(MAJOR)$(MINOR).dll`

    3. Next at 430eabfe139, forwarding DLL was added for binary
       compatibility against extension libraries.

    Use RUBY_DEBUG instead of NDEBUG

    Assertions in header files slows down an interpreter, so they should be
    turned off by default (simple `make`). To enable them, define a macro
    `RUBY_DEBUG=1` (e.g. `make cppflags=-DRUBY_DEBUG` or use `#define` at
    the very beginning of the file. Note that even if `NDEBUG=1` is defined,
    `RUBY_DEBUG=1` enables all assertions.
    [Feature #16837]
    related: https://github.com/ruby/ruby/pull/3120

    `assert()` lines in MRI *.c is not disabled even if `RUBY_DEBUG=0` and
    it can be disabled with `NDEBUG=1`. So please consider to use
    `RUBY_ASSERT()` if you want to disable them when `RUBY_DEBUG=0`.

    [ruby/rdoc] Treat multiple Ruby methods calling the same C method as aliases

    Previously, only calls to rb_define_alias were treated as aliases.
    This treats calls to rb_define_method with the same C function as
    aliases, with the first function defined being the primary method.

    This move the dedup code from the C parser to AnyMethod, and has
    AnyMethod look in its aliases to find the call_seq.

    Switch the deduplication code to remove lines matching one of the
    other aliases, instead of only keeping lines matching the current
    alias.  The previous approach could eliminate all call_seq lines
    in cases where no line matched.  This was necessary to pass
    tests when call_seq does deduplication by default.

    The only change to the darkfish template is to not perform
    unnecessary work by deduplicating twice.

    Allow Dir.home to work for non-login procs when $HOME not set

    Allow the 'Dir.home' method to reliably locate the user's home directory when
    all three of the following are true at the same time:

        1. Ruby is running on a Unix-like OS
        2. The $HOME environment variable is not set
        3. The process is not a descendant of login(1) (or a work-alike)

    The prior behavior was that the lookup could only work for login-descended
    processes.

    This is accomplished by looking up the user's record in the password database
    by uid (getpwuid_r(3)) as a fallback to the lookup by name (getpwname_r(3))
    which is still attempted first (based on the name, if any, returned by
    getlogin_r(3)).

    If getlogin_r(3), getpwnam_r(3), and/or getpwuid_r(3) is not available at
    compile time, will fallback on using their respective non-*_r() variants:
    getlogin(3), getpwnam(3), and/or getpwuid(3).

    The rationale for attempting to do the lookup by name prior to doing it by uid
    is to accommodate the possibility of multiple login names (each with its own
    record in the password database, so each with a potentially different home
    directory) being mapped to the same uid (as is explicitly allowed for by
    POSIX; see getlogin(3posix)).

    Preserves the existing behavior for login-descended processes, and adds the
    new capability of having Dir.home being able to find the user's home directory
    for non-login-descended processes.

    Fix origin iclass pointer for modules

    If a module has an origin, and that module is included in another
    module or class, previously the iclass created for the module had
    an origin pointer to the module's origin instead of the iclass's
    origin.

    Setting the origin pointer correctly requires using a stack, since
    the origin iclass is not created until after the iclass itself.
    Use a hidden ruby array to implement that stack.

    Correctly assigning the origin pointers in the iclass caused a
    use-after-free in GC.  If a module with an origin is included
    in a class, the iclass shares a method table with the module
    and the iclass origin shares a method table with module origin.

    Mark iclass origin with a flag that notes that even though the
    iclass is an origin, it shares a method table, so the method table
    should not be garbage collected.  The shared method table will be
    garbage collected when the module origin is garbage collected.
    I've tested that this does not introduce a memory leak.

    This change caused a VM assertion failure, which was traced to callable
    method entries using the incorrect defined_class.  Update
    rb_vm_check_redefinition_opt_method and find_defined_class_by_owner
    to treat iclass origins different than class origins to avoid this
    issue.

    This also includes a fix for Module#included_modules to skip
    iclasses with origins.

    test/ruby/test_optimization.rb: Proc creation test should count :T_DATA

    instead of :TOTAL of ObjectSpace.count_objects.

    This test had failed very occasionally:

    https://rubyci.org/logs/rubyci.s3.amazonaws.com/centos8/ruby-master/log/20200521T033004Z.fail.html.gz
    ```
      1) Failure:
    TestRubyOptimization#test_block_parameter_should_not_create_objects [/home/chkbuild/chkbuild/tmp/build/20200521T033004Z/ruby/test/ruby/test_optimization.rb:713]:
    <0> expected but was
    <407>.
    ```

    This test of lazy proc creation checks if no object is created during a
    method call.  However, calling a method itself increases the count of
    objects because method cache is now an object (T_MEMO).
    The reason why this test rarely fails is because the test was buggy; it
    checked the count of :TOTAL, but :TOTAL count changes only when the GC
    heap is expanded.  Creating one object rarely causes heap expansion.
    The test must have checked not only :TOTAL but also the count of :FREE.

    Instead, this change more directly checks :T_DATA.  Note that a Proc
    object is T_DATA.

    Only marked objects should be considered movable

    Ruby's GC is incremental, meaning that during the mark phase (and also
    the sweep phase) programs are allowed to run.  This means that programs
    can allocate objects before the mark or sweep phase have actually
    completed.  Those objects may not have had a chance to be marked, so we
    can't know if they are movable or not. Something that references the
    newly created object might have called the pinning function during the
    mark phase, but since the mark phase hasn't run we can't know if there
    is a "pinning" relationship.

    To be conservative, we must only allow objects that are not pinned but
    also marked to move.

    Use a pinning list for keeping objects alive during assembly.

    The GC will not disassemble incomplete instruction sequences.  So it is
    important that when instructions are being assembled, any objects the
    instructions point at should not be moved.

    This patch implements a fixed width array that pins its references.
    When the instructions are done being assembled, the pinning array goes
    away and the objects inside the iseqs are allowed to move.

    We observed combination of multiple __builtin_assume() can cause

    To avoid this problem, __builtin_assume() is from clang-7.

    ext/json/parser/prereq.mk: remove type-limit warning if char is unsigned

    Ragel generates a code `0 <= (*p)` where `*p` is char.
    As char is unsigned by default on arm and RISC-V, it is warned by gcc:

    ```
    compiling parser.c
    parser.c: In function ‘JSON_parse_string’:
    parser.c:1566:2: warning: comparison is always true due to limited range of data type [-Wtype-limits]
      if ( 0 <= (*p) && (*p) <= 31 )
      ^
    parser.c:1596:2: warning: comparison is always true due to limited range of data type [-Wtype-limits]
      if ( 0 <= (*p) && (*p) <= 31 )
      ^
    ```

    This change removes the warning by substituting the condition with
    `0 <= (signed char)(*p)`.

    [ruby/openssl] ssl: temporarily remove SSLContext#add_certificate_chain_file

    Let's revert the changes for now, as it cannot be included in the 2.2.0
    release.

    My comment on #257:

    > A blocker is OpenSSL::SSL::SSLContext#add_certificate_chain_file. It
    > has a pending change and I don't want to include it in an incomplete
    > state.
    >
    > The initial implementation in commit 46e4bdba40c5 was not really
    > useful. The issue is described in #305. #309 extended it
    > to take the corresponding private key together. However, the new
    > implementation was incompatible on Windows and was reverted by #320 to
    > the initial one.
    >
    > (The prerequisite to implement it in) an alternative way is #288, and
    > it's still cooking.

    This effectively reverts the following commits:

     - dacd08937ccd ("ssl: suppress test failure with SSLContext#add_certificate_chain_file", 2020-03-09)
     - 46e4bdba40c5 ("Add support for SSL_CTX_use_certificate_chain_file. Fixes #254.", 2019-06-13)

    [ruby/openssl] pkey: add PKey#inspect and #oid

    Implement OpenSSL::PKey::PKey#oid as a wrapper around EVP_PKEY_id().
    This allows user code to check the type of a PKey object.

    EVP_PKEY can have a pkey type for which we do not provide a dedicated
    subclass. In other words, an EVP_PKEY that is not any of {RSA,DSA,DH,EC}
    can exist. It is currently not possible to distinguish such a pkey.

    Also, implement PKey#inspect to include the key type for convenience.

    Stop always inlining not-optimized get/setivar

    As we have the optimization in _mjit_compile_ivar.erb, we don't use
    these functions if we successfully optimize ivars. Therefore it's
    consuming code size where we can't optimize it well.

    To decrease code size, we'd better avoid inlining them.

    ext/fiddle/extconf.rb: check if ffi_closure_alloc is available

    to define HAVE_FFI_CLOSURE_ALLOC.
    The macro is used in closure.c, so have_func check is needed.

    If pkg-config is not installed, extconf.rb fails to detect the version
    of libffi, and does not add "-DUSE_FFI_CLOSURE_ALLOC=1" even when system
    libffi version is >= 3.2.

    If USE_FFI_CLOSURE_ALLOC is not defined, closure.c attempts to check if
    HAVE_FFI_CLOSURE_ALLOC is defined or not, but have_func was removed with
    528a3a17977aa1843a26630c96635c3cb161e729, so the macro is always not
    defined.

    This resulted in this deprecation warning:

    Expose SSLContext#extra_chain_cert in Net::HTTP

    Currently, Net::HTTP can only send a single SSL certificate when it
    establishes a connection. Some use-cases involve sending an entire
    certificate chain to the destination; for this, SSLContext supports
    assigning to #extra_chain_cert=.

    This adds support in Net::HTTP for exposing this underlying SSLContext
    property to end-users. [Feature #9758]

    This limit was introduced on Nov 20 1996
    in 554b989ba1623b9f6a0b76f00824c83a23fbcbc1

    Apparently to protect from a buffer overflow:

      * eval.c (f_missing): オブジェクトの文字列表現が長すぎる時バッファ
              を書き潰していた

    However I tested that path with very large strings
    and it works fine.

    rb_str_new: hoist RB_CONSTANT_P out of function

    https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html says:

    > GCC never returns 1 when you call the inline function with a string
    > constant or ...

    Because rb_str_new and familiy take string constants, it was a bad idea
    for them to contain RB_CONSTANT_P.  We should instead do so in
    corresponding macros. [ruby-core:98212]

  Author: David Rodríguez <deivid.rodriguez@riseup.net>
  Date:   2020-03-05 05:10:31 +0900

    [rubygems/rubygems] Revert adding loaded specs to `Gem::Specification.stubs` and `Gem::Specification.stubs_for`

    The rationale is that:

    * The change has caused realworld issues. See for example
    https://github.com/ruby/did_you_mean/issues/117 and specifically [this
    comment](https://github.com/ruby/did_you_mean/issues/117#issuecomment-482733159)
    for a great explanation of the issue it caused for `did_you_mean`.

    * The change also causes problems for our development workflows. For
    example, because of it, our `bundler` specs cannot currently be run with
    `bin/rake` and we have to use `bin/rspec` or `bin/parallel_spec`
    directly. The explanation for this is:

      - Our specs install test dependencies to `tmp` before running specs.
      - `rake` is one of these test dependencies.
      - Before installing each test dependency, we check whether it has
      matching installed specs: https://github.com/rubygems/rubygems/blob/2bbcdcde08b90d4ef03da8fb1f7a8a3313e13bb8/bundler/spec/support/rubygems_ext.rb#L109-L114.

      - Normally, if `rake` has not yet been installed to `tmp`, this check
      fails and `rake` is installed, but since the loaded specs are now
      added to `Gem::Specification.stubs` and `rake`'s specification _is_
      loaded because we're running through `bin/rake`, the check incorrectly
      assumes that `rake` is already installed to `tmp` and skips
      installation.
      - At a later point the specs check whether `rake` is actually
      installed and fail if it's not: https://github.com/rubygems/rubygems/blob/2bbcdcde08b90d4ef03da8fb1f7a8a3313e13bb8/bundler/spec/support/builders.rb#L372-L383

    Essentially, both of the issues are the same. If at runtime we change
    the location of gems, we'll _want_ to not consider loaded specifications
    when dealing with the new gem location, because the loaded
    specifications have not been loaded from there. Loaded specifications is
    something different from installed stub specifications and those should
    not be mixed.

    The PR still seemed to have fixed an issue, so I did my archaeology job
    and investigated the original issue to double check if reverting is ok.
    The logs for the original error can be found here:
    https://ci.appveyor.com/project/rubygems/rubygems/build/1172/job/ogubyucpljcv22ux.

    So I installed ruby 2.4.4, checked out the commit reference before the
    offending PR, and the exact error reproduced. :tada:

    rake aborted!
    Command failed with status (1)

    Tasks: TOP => test
    ```

    Now the explanation of the error:

    * Rubygems base `TestCase` class requires `bundler` because some tests
    use `bundler`:
    https://github.com/rubygems/rubygems/blob/2bbcdcde08b90d4ef03da8fb1f7a8a3313e13bb8/lib/rubygems/test_case.rb#L26

    * That `require` (our custom rubygems require) would activate the
    default bundler spec (1.16.1 for ruby 2.4.4) but then overwrite it with
    a 1.16.2 version (the locally provided bundler those days) due to [this
    old
    hack](https://github.com/rubygems/bundler/blob/9f7bf0ac3ab8d995e3a274cec3c292a5203f4534/lib/bundler/version.rb#L7-L23).

    * Rubygems base `TestCase` class requires `rubygems/rdoc`:
    https://github.com/rubygems/rubygems/blob/2bbcdcde08b90d4ef03da8fb1f7a8a3313e13bb8/lib/rubygems/test_case.rb#L1536

    * And that file ends up calling `Gem.finish_resolve`:
    https://github.com/rubygems/rubygems/blob/2bbcdcde08b90d4ef03da8fb1f7a8a3313e13bb8/lib/rubygems/rdoc.rb#L13

    * `Gem.finish_resolve` adds the currently loaded specs to the
    resolution:
    https://github.com/rubygems/rubygems/blob/2bbcdcde08b90d4ef03da8fb1f7a8a3313e13bb8/lib/rubygems.rb#L235

    * That means it would try to resolve bundler 1.16.2, but no
    specification for that version was installed since the default was
    1.16.1. That explains why upgrading to rubygems 2.7.7 fixed the issue,
    since it provided bundler 1.16.2 by default so there was not bundler
    version discrepancy.

    After understanding the error, I conclude that:

    * Only this part of the original patch was actually needed to resolve
    the error, not any of the changes in `Gem::Specification.stubs` and
    `Gem::Specification.stubs_for`:

    ```diff
    diff --git a/lib/rubygems/test_case.rb b/lib/rubygems/test_case.rb
    index f1cd3d274c..92c848e870 100644
    --- a/lib/rubygems/test_case.rb
    +++ b/lib/rubygems/test_case.rb
    @@ -13,6 +13,15 @@ else
       require 'rubygems'
     end

    +# If bundler gemspec exists, add to stubs
    +bundler_gemspec = File.expand_path("../../../bundler/bundler.gemspec", __FILE__)
    +if File.exist?(bundler_gemspec)
    +  Gem::Specification.dirs.unshift File.dirname(bundler_gemspec)
    +  Gem::Specification.class_variable_set :@@stubs, nil
    +  Gem::Specification.stubs
    +  Gem::Specification.dirs.shift
    +end
    +
     begin
       gem 'minitest'
     rescue Gem::LoadError
    ```

    So, I propose to revert adding loaded specification to
    `Gem::Specification.stubs` and `Gem::Specification.stubs_for` because I
    think it's safe, it fixes the issues caused by their addition, and it
    simplifies `Gem::Specification` code, which is already complicated
    enough.

    [rubygems/rubygems] Let `@@stubs_by_name` to be incrementally populated again.

    Originally, the call to `.stubs_for` allowed to incrementally populate
    the `@@stubs_by_name` (especially see the `"#{name}-*.gemspec"` pattern
    in 4fa03bb7aac9f25f44394e818433fdda9962ae8d). Now it looks like it
    expects that all stubs are loaded, but the `.stubs_for` still matches
    the .gemspec files by the `name` pattern:

    https://github.com/rubygems/rubygems/blob/6d45e0f7ac1caca22900e39f703e226c4cfdebf7/lib/rubygems/specification.rb#L845

    I think this was done by mistake incrementally by PR #1239 and
    4cee8ca9199ac7b3ab8647e0b78615f55d3eb02b. I think the best option is to
    get back to the original implementation, to let RubyGems incrementally
    populate the array. Other option would be to replace the logic in
    `.stub_for` by call to `.stubs`, but the means the performance
    improvement from the original commit was lost.

    [rubygems/rubygems] Fix incorrect bundler version being required

    In ruby 2.7.0, there's a slight change in bundler's default gemspec file
    where the executable folder of the bundler gem is `libexec` instead of
    `exe`. I made that change in https://github.com/ruby/ruby/pull/2380 to
    try to simplify the integration of the `bundler` gem with upstream,
    minimizing the number of changes that need to be made to the gemspec to
    adapt to the structure of ruby-core.

    That worked ok, expected for this issue. The new name of the folder
    including the executable files uncovered a bug in rubygems, which is the
    following:

    * In order to be able to use newer versions of default gems, `rubygems`
    ships with a customized `require` that has knowledge about which files
    belong to which default gem. If one of these files is required,
    `rubygems` will detect that and activate its gem mechanism to choose the
    newest version of the corresponding default gem present in the system
    (unless a different version has already been activated). It's this part
    of the custom require:

    https://github.com/rubygems/rubygems/blob/ea3e6f194df500b028b52b3b64decbd3df1d5ab0/lib/rubygems/core_ext/kernel_require.rb#L77-L85

    * In order to do that, `rubygems` registers a map of default gems and
    their files when it is first required:

    https://github.com/rubygems/rubygems/blob/ea3e6f194df500b028b52b3b64decbd3df1d5ab0/lib/rubygems.rb#L1247-L1276

    As explained in the method's header, two types of default gem
    specifications are supported. One of the formats is the style used by
    some ruby-core gemspec files, where paths inside the `spec.files` array
    don't include the `spec.require_paths` part. So in this "old style", if
    a gem ships with a `lib/bundler.rb` file, it will be registered in this
    array as `spec.files = ["bundler.rb"]`, not as `spec.files =
    ["lib/bundler.rb"]`. The `Gem.register_default_spec` method "detects"
    this style by making sure that none of the files in the `spec.files`
    array start with any of the `spec.require_paths`.

    * Since in ruby 2.7 the default specification file of the `bundler` gem
    includes a `libexec/bundle` file, this check would no longer work
    correctly, because even though the specification file is still "old
    style", it has one registered file which starts with "lib", one of the
    "require paths" of the gem.

    * This means that the gem is incorrectly detected as "new style", but
    since none of the paths start with "lib/", no files are actually
    registered, so the gem is not being considered a default gem, and thus
    the default version is always used with no possibility of being
    "upgraded".

    The fix of the problem is simple: check that no files start with `lib/`
    (or any other require paths), instead of with "lib" which doesn't
    exclude other potential "non requirable folder" starting with lib, like
    in the `bundler` case.

    [rubygems/rubygems] Remove misleading comments

    `site_dir`, or `vendor_dir`, is the location where the default version
    of bundler & rubygems gets installed. These folders are placed directly
    in the LOAD_PATH, so they cannot hold any nested gem directory
    structure. So a single copy of either rubygems or bundler can be placed
    in these folders.

    What the tests are actually testing is the TODO comment that I'm
    removing: that installing the default copy of bundler doesn't affect any
    already installed copies of bundler as regular gems.

    [rubygems/rubygems] Fix race condition on bundler's parallel installer

    When installing in parallel, bundler creates several `Gem::Installer`
    instances that run in parallel. These installers access the `@@all` class
    variable of `Gem::Specification` concurrently.

    If a concurrent thread calls `Gem::Specification.reset` (resetting
    `@all` to `nil`) while another thread is running
    `Gem::Specification._all` or another method that expects `@@all` to be
    loaded and not `nil`, that can result in `Enumerable` methods being
    called on `nil`, resulting in crashes.

    I fix it by protecting the other concurrent access to the `@all`
    variable.

    Allow global variables to move

    This patch allows global variables that have been assigned in Ruby to
    move.  I added a new function for the GC to call that will update
    global references and introduced a new callback in the global variable
    struct for updating references.

    Only pure Ruby global variables are supported right now, other
    references will be pinned.

    `T_MOVED` should never be pushed on the mark stack

    No objects should ever reference a `T_MOVED` slot.  If they do, it's
    absolutely a bug.  If we kill the process when `T_MOVED` is pushed on
    the mark stack it will make it easier to identify which object holds a
    reference that hasn't been updated.

    Always correct sp on leave cancel

    Even if local stack optimization is not used and values are written to
    VM stack, the stack pointer itself may not be moved properly. So this
    should be always moved on JIT cancellation.

    By the way it's hard to write a test for this because if we try to
    generate an interrupt, it will be a method call and it consumes the
    interrupt by itself on popping a frame.

    We only need to loop `T_MASK` times once.  Also, not every value between
    0 and `T_MASK` is an actual Ruby type.  Before this change, some
    integers were being added to the result hash even though they aren't
    actual types.  This patch omits considered / moved entries that total 0,
    cleaning up the result hash and eliminating these "fake types".

    Optimize sin/cos

    GCC/Clang can optimize to calculate `sin(x)` and `cos(x)` at once,
    when the both are closely called on the same argument.

    Similar optimization is possible for `__sinpi(x)` and `__cospi(x)`
    if available, which calculate arguments in radian, i.e.

    Avoid infinite times of JIT compaction

    It's to avoid memory leak for actual usage (because they don't get
    unloaded properly), but also for fixing CI timed out due to JIT
    compaction taking too long time on --jit-wait (which runs every time)

    spec/ruby/core/process/clock_getres_spec.rb: lax the resolution limit

    Android is Linux, but the clock resolution is 10 milliseconds.
    I think that 1 microsecond is too strict for embedded environment.
    This change laxes the limit to 10 milliseconds.

    internal/process.h: forgot to guard "#ifdef HAVE_WORKING_FORK"

  Date:   2020-05-02 21:34:10 +0900

    internal/process.h: add a no-warning simple wrapper for fork(2)

    As fork(2) is deprecated, its calls must be guarded by
    `COMPILER_WARNING_IGNORED(-Wdeprecated-declarations)`.
    All usages of fork(2) in process have been alread guarded.  A new call
    to fork(2) was added in ruby.c with f22c4ff359498ab342e4b6d6feb21af6004ee270.
    This caused a build failure on Solaris 11.

    It may hide a bug to guard big code unnecessarily, so this change
    introduces a simple wrapper "rb_fork" whose definition is guarded, and
    replaces all calls to fork(2) with the wrapper function.

    Do not stop the world during JIT compaction

    Running C compiler for JIT compaction inside a critical section may lock
    main thread for a long time when it triggers GC. As I'm planning to
    increase this duration a bit, I'd like to make sure this doesn't stop
    the world.

    For now, I chose to give up unloading units when it's during JIT
    compaction, assuming other calls may unload them later.

    [rubygems/rubygems] Make the test suite pass under `umask 077`

    Some tests had failed under `umask 077` mode.  As far as I investigated,
    there is no actual bug.  All failures were caused by tests that create a
    wrong-permission file or expect wrong permission.

    This changeset fixes the tests.

    rb_method_entry() returns valid me.

    search_method() can return invalid method, but vm_defined() checks
    it as valid method entry. This is why defined?(foo) if foo is undef'ed.
    To solve this problem, check invalidation and return NULL.

    and I don't think anybody has been working on it right now. To make CI
    result report of s390x-linux useful, let's skip it until the test is
    improved to be more stable.

    fix compiler error on gcc 4.x

    It seems gcc prior to 5 suffered from preprocessor bug.  We have to
    provide workarounds.

    See https://github.com/ruby/ruby/runs/591138012

    ----

    Here is something interesting.  According to C99, strictly speaking,
    the gcc behaviour was in fact legal(!) and everything else were
    wrong.  This was not a bug of gcc, rather a bug of the ISO C Standard.
    This defect was reported to the committee as DR#412, and fixed
    accordingly.  All tested compilers now conform C17's updated
    preprocessor description.

    See http://www.open-std.org/JTC1/SC22/WG14/www/docs/dr_412.htm

    Invalidate fastpath when calling attr_writer by super

    We started to use fastpath on invokesuper when a method is not refinements
    since 5c27681813, but we shouldn't have used fastpath for attr_writer either.

    `cc->aux_.attr_index` is for an actual receiver class, while we store
    its superclass in `cc->klass` and therefore there's no way to properly
    invalidate attr_writer's inline cache when it's called by super.

    [Bug #16785]

    I suspect the same bug also exists in attr_reader. I'll address that in
    another commit.

    Unify vm benchmark prefixes to vm_ (#3028)

    The vm1_ prefix and vm2_ had had special meaning until
    820ad9cb1d72d0897b73dae282df3793814b27e8 and
    12068aa4e980ab32a0438408a519030e65dabf5e. AFAIK there's no special
    meaning in vm3_ prefix.

    As they have confused people (like "In `benchmark` what is difference
    between `vm1_`, `vm2_` and `vm3_`"), I'd like to remove the obsoleted
    prefix as we obviated that two years ago.

    and I deleted this capability in an early stage of YARV-MJIT development:
    https://github.com/k0kubun/yarv-mjit/commit/0ab130feeefc2b9078a1077e4fec93b3f5e45d07

    I suspect either of the following things could be the cause:

    * Directly calling vm_call_cfunc requires more optimization effort in GCC,
      resulting in 30ms-ish compilation time increase for such methods and
      decreasing the number of methods compiled in a benchmarked period.

    * Code size increase => icache miss hit

    These hypotheses could be verified by some methodologies. However, I'd
    like to introduce this regardless of the result because this blocks
    inlining C method's definition.

    I may revert this commit when I give up to implement inlining C method
    definition, which requires this change.

    Microbenchmark-wise, this gives slight performance improvement:

    include what you use.

    This reverts commit 443389effc37308ce1a3c3a840082a344fc6af56.
    This reverts commit d94960f22ec2de3a3855305cb51343806d2b46c7.

    Inclusion of header files must be explicit.  Every file shall directly
    include what is necessary.

    https://github.com/include-what-you-use/include-what-you-use says:

    > When every file includes what it uses, then it is possible to edit any
    > file and remove unused headers, without fear of accidentally breaking
    > the upwards dependencies of that file. It also becomes easy to
    > automatically track and update dependencies in the source code.

    Though we don't use iwyu itself, the principle quoted above is a good
    thing that we can agree.

    Now that include guards were added to every and all of the headers
    inside of our project this changeset does not increase compile time, at
    least on my machine.

    add #include guard hack

    According to MSVC manual (*1), cl.exe can skip including a header file
    when that:

    - contains #pragma once, or
    - starts with #ifndef, or
    - starts with #if ! defined.

    GCC has a similar trick (*2), but it acts more stricter (e. g. there
    must be _no tokens_ outside of #ifndef...#endif).

    Sun C lacked #pragma once for a looong time.  Oracle Developer Studio
    12.5 finally implemented it, but we cannot assume such recent version.

    This changeset modifies header files so that each of them include
    strictly one #ifndef...#endif.  I believe this is the most portable way
    to trigger compiler optimizations. [Bug #16770]

    Enable fastpath on invokesuper (#3021)

    Fastpath has not been used for invokesuper since it has set vm_call_super_method on every invocation.
    Because it seems to be blocked only by refinements, try enabling fastpath on invokesuper when cme is not for refinements.

    While this patch itself should be helpful for VM performance, a part of this patch's motivation is to unblock inlining invokesuper on JIT.

    Don't require sub-word atomics

    On some architectures (like RISC-V) sub-word atomics are only available
    when linking against -latomic, but the configure script doesn't do that,
    causing the atomic checks to fail and the resulting ruby binary is
    non-functional.  Ruby does not use sub-word atomic operations, rb_atomic_t
    is defined to unsigned int, so use unsigned int when checking for atomic
    operations.

    Turn class variable warnings into exceptions

    This changes the following warnings:

    * warning: class variable access from toplevel
    * warning: class variable @foo of D is overtaken by C

    into RuntimeErrors.  Handle defined?(@@foo) at toplevel
    by returning nil instead of raising an exception (the previous
    behavior warned before returning nil when defined? was used).

    Refactor the specs to avoid the warnings even in older versions.
    The specs were checking for the warnings, but the purpose of
    the related specs as evidenced from their description is to
    test for behavior, not for warnings.

    ruby3_rstring_getmem: suppres warning

    icc warns at this line.

    > include/ruby/3/core/rstring.h(126): warning #413: variable "retval" has an uninitialized const field
    >           struct RString retval;
    >                          ^

    This must not be a problem because uninitialized const field is not used
    at all.  But the warnings are annoying.  Let us suppress them.

    RUBY3_ASSUME: suppress warnings on icc

    icc warns side effects for RUBY3_ASSUME like this:

    > ./include/ruby/3/value_type.h(202): warning #2261: __assume expression with side effects discarded
    >           RUBY3_ASSUME(RB_FLONUM_P(obj));
    >                        ^

    Which is a false positive (RB_FLONUM_P has no side effect).  It seems
    there is no way for us to tell icc that a functin is safe inside of
    __assume.   Just suppress the warning instead.

    should check pending interrupts correctly.

    rb_uninterruptible() disables any interrupts using handle_interrupt
    feature (This function is used by `p`).
    After this function, pending interrupts should be checked correctly,
    however there is no chance to setup interrupt flag of working
    threads, it means that nobody checks pending interrupts.
    For example, it ignores terminate signal delivered at the end
    of main thread and program can't stop.

    This patch set interrupt flag if there are pending interrupts.

    RARRAY_EMBED_LEN/RSTRING_EMBED_LEN: add RUBY3_CAST

    RUBY3_CAST is a macro to suppress g++/clang++ warnings about C-style
    casts.  Though Ruby core don't have to bother C++ situations, extension
    libraries can benefit from this.

    RUBY3_HAS_BUILTIN: fix for nonexistent builtin

    Trying to fix icc breakage:
    https://rubyci.org/logs/rubyci.s3.amazonaws.com/icc-x64/ruby-master/log/20200408T050004Z.fail.html.gz

    It seems the macro had problems when a builtin does not exist for the
    target compiler.  Force evaluete to 0 then, by adding 0 to the
    expression.

    webrick/ssl: More keyUsage for self-signed certs

    Chrome 75+ started to strictly enforce X.509 keyUsage against TLS server
    certificates. Webrick supports generating instant self-signed
    certificates for debugging purpose and these certificates lacks required
    keyUsage for modern TLS. So adding the following keyUsages:

    - digitalSignature (for server authentication)
    - keyAgreement (for DH key exchange)
    - dataEncipherment (for data encryption)

    Use `--depth` on pull request

    `--shallow-since=yesterday` for COMMIT_NUMBER_OF_DAY of `tool/actions-commit-info.sh`.
    COMMIT_NUMBER_OF_DAY is mainly for master branch.
    And `--shallow-since=yesterday` may fail on pull request.
    So this revert to `--depth` on pull request.

    Clear all trace events during teardown

    Since 0c2d81dada, not all trace events are cleared during VM teardown.
    This causes a crash when there is a tracepoint for
    `RUBY_INTERNAL_EVENT_GC_EXIT` active during teardown.

    The commit looks like a refactoring commit so I think this change was
    unintentional.

    It is acceptable as it fails at most twice per year, but it would be
    good to use near time objects to reduce the possibility.

    Set external encoding correctly for File.open('f', FILE::BINARY) on Windows

    Previously, the external encoding was only set correctly for
    File::BINARY if keyword arguments were provided.  This copies
    the logic for the keyword arguments case to the no keyword
    arguments case.  Possibly it should be refactored into a
    separate function.

    test/json/test_helper.rb: Do not add a relative path to $LOAD_PATH

    ... because it conflicts with test/ruby/test_m17n.rb.

    An exception `incompatible character encodings: UTF-8 and UTF-16BE`
    occurs when:

    * a non-existence relative path is added to $LOAD_PATH,
    * ASCII-incompatible encoding is set to default_external, and
    * some file is loaded.

    ```
    $LOAD_PATH << "no_existing_dir"
    Encoding.default_external = Encoding::UTF_16BE
    load "dummy.rb" #=> incompatible character encodings: UTF-8 and UTF-16BE
    ```

    This issue can be actually observed by a combination of out-of-place
    build and the following command:

    make test-all TESTS="json ruby/m17n -n test_object_inspect_external"

    http://ci.rvm.jp/logfiles/brlog.trunk-test-random.20200322-221411

    ASCII-incompatible default external encoding assumes that the cwd is the
    encoding, and it is attempted to beconcatenated with a non-existence
    relative LOAD_PATH UTF-8 string, which causes the exception.

    This changeset avoids a relative path.

    Support obj.clone(freeze: true) for freezing clone

    This freezes the clone even if the receiver is not frozen.  It
    is only for consistency with freeze: false not freezing the clone
    even if the receiver is frozen.

    Because Object#clone is now partially implemented in Ruby and
    not fully implemented in C, freeze: nil must be supported to
    provide the default behavior of only freezing the clone if the
    receiver is frozen.

    This requires modifying delegate and set, to set freeze: nil
    instead of freeze: true as the keyword parameter for
    initialize_clone.  Those are the two libraries in stdlib that
    override initialize_clone.

    Implements [Feature #16175]

    Reduce allocations for keyword argument hashes

    Previously, passing a keyword splat to a method always allocated
    a hash on the caller side, and accepting arbitrary keywords in
    a method allocated a separate hash on the callee side.  Passing
    explicit keywords to a method that accepted a keyword splat
    did not allocate a hash on the caller side, but resulted in two
    hashes allocated on the callee side.

    This commit makes passing a single keyword splat to a method not
    allocate a hash on the caller side.  Passing multiple keyword
    splats or a mix of explicit keywords and a keyword splat still
    generates a hash on the caller side.  On the callee side,
    if arbitrary keywords are not accepted, it does not allocate a
    hash.  If arbitrary keywords are accepted, it will allocate a
    hash, but this commit uses a callinfo flag to indicate whether
    the caller already allocated a hash, and if so, the callee can
    use the passed hash without duplicating it.  So this commit
    should make it so that a maximum of a single hash is allocated
    during method calls.

    To set the callinfo flag appropriately, method call argument
    compilation checks if only a single keyword splat is given.
    If only one keyword splat is given, the VM_CALL_KW_SPLAT_MUT
    callinfo flag is not set, since in that case the keyword
    splat is passed directly and not mutable.  If more than one
    splat is used, a new hash needs to be generated on the caller
    side, and in that case the callinfo flag is set, indicating
    the keyword splat is mutable by the callee.

    In compile_hash, used for both hash and keyword argument
    compilation, if compiling keyword arguments and only a
    single keyword splat is used, pass the argument directly.

    On the caller side, in vm_args.c, the callinfo flag needs to
    be recognized and handled.  Because the keyword splat
    argument may not be a hash, it needs to be converted to a
    hash first if not.  Then, unless the callinfo flag is set,
    the hash needs to be duplicated.  The temporary copy of the
    callinfo flag, kw_flag, is updated if a hash was duplicated,
    to prevent the need to duplicate it again.  If we are
    converting to a hash or duplicating a hash, we need to update
    the argument array, which can including duplicating the
    positional splat array if one was passed.  CALLER_SETUP_ARG
    and a couple other places needs to be modified to handle
    similar issues for other types of calls.

    This includes fairly comprehensive tests for different ways
    keywords are handled internally, checking that you get equal
    results but that keyword splats on the caller side result in
    distinct objects for keyword rest parameters.

    Included are benchmarks for keyword argument calls.
    Brief results when compiled without optimization:

      def kw(a: 1) a end
      def kws(**kw) kw end
      h = {a: 1}

      kw(a: 1)       # about same
      kw(**h)        # 2.37x faster
      kws(a: 1)      # 1.30x faster
      kws(**h)       # 2.19x faster
      kw(a: 1, **h)  # 1.03x slower
      kw(**h, **h)   # about same
      kws(a: 1, **h) # 1.16x faster
      kws(**h, **h)  # 1.14x faster

    Make {**{}} return unfrozen empty hash

    Previously, method call keyword splats and hash keyword splats
    were compiled exactly the same.  This is because parse-wise, they
    operate on identical nodes when it comes to compiling the **{}.

    Fix this by using an ugly hack of temporarily modifying the
    nd_brace flag in the method call keyword splat case.  Inside
    compile_hash, only optimize the **{} case for hashes where the
    nd_brace flag has been modified to reflect we are in the method
    call keyword splat case and it is safe to do so.

    Since compile_keyword_args is only called in one place, move the
    keyword_node_p call out of that method to the single caller to
    avoid duplicating the code.

    hash.c: Do not use the fast path (rb_yield_values) for lambda blocks

    As a semantics, Hash#each yields a 2-element array (pairs of keys and
    values).  So, `{ a: 1 }.each(&->(k, v) { })` should raise an exception
    due to lambda's arity check.
    However, the optimization that avoids Array allocation by using
    rb_yield_values for blocks whose arity is more than 1 (introduced at
    b9d29603375d17c3d1d609d9662f50beaec61fa1 and some commits), seemed to
    overlook the lambda case, and wrongly allowed the code above to work.

    This change experimentally attempts to make it strict; now the code
    above raises an ArgumentError.  This is an incompatible change; if the
    compatibility issue is bigger than our expectation, it may be reverted
    (until Ruby 3.0 release).

    Avoid referring to an old value of realloc

    OpenBSD RubyCI has failed with SEGV since 4bcd5981e80d3e1852c8723741a0069779464128.
    https://rubyci.org/logs/rubyci.s3.amazonaws.com/openbsd-current/ruby-master/log/20200312T223005Z.fail.html.gz

    This was because `status->cc_entries` could be stale after `realloc` call
    for inlined iseqs.

    digest: do not depend on ext/openssl/deprecation.rb

    ext/openssl/deprecation.rb has been removed in ext/openssl upstream[1].

    It was originally introduced to detect and prevent linking against
    Apple's bundled (and very outdated) version of OpenSSL. It is long gone
    and the header files do not exist in current versions of macOS.

    The dependency in ext/digest was introduced by commit 26e258c807c2.
    Note that the original issue[2] is resolved without this dependency.
    The commit also added the pkg_config("openss") call to match what
    ext/openssl does.

    Don't display singleton class in Method#inspect unless method defined there

    Previously, if an object has a singleton class, and you call
    Object#method on the object, the resulting string would include
    the object's singleton class, even though the method was not
    defined in the singleton class.

    Change this so the we only show the singleton class if the method
    is defined in the singleton class.

    Do not autosplat when calling procs that accept rest and keywords

    When providing a single array to a block that takes a splat, pass the
    array as one argument of the splat instead of as the splat itself,
    even if the block also accepts keyword arguments.  Previously, this
    behavior was only used for blocks that did not accept keywords.

    way that it ended up being set to 1 on OpenBSD.  However, that results
    in SIGABRT when running make test-all, inside ffi_closure_free.
    Setting USE_FFI_CLOSURE_ALLOC back to 0 fixes the issue.

    thread_pthread.c: allocate sigaltstack before pthread_create

    A new (not-initialized-yet) pthread attempts to allocate sigaltstack by
    using xmalloc.  It may cause GC, but because the thread is not
    initialized yet, ruby_native_thread_p() returns false, which leads to
    "[FATAL] failed to allocate memory" and exit.

    In fact, we can observe the error message in the log of OpenBSD CI:
    https://rubyci.org/logs/rubyci.s3.amazonaws.com/openbsd-current/ruby-master/log/20200306T083005Z.log.html.gz

    This changeset allocates sigaltstack before pthread is created.

    Use examples that also demonstrate factors with multiplicity
    other than 1, and avoid factors/multiplicities with the same value.
    Also add the decomposition written as simple mathematical expression.

    This also fixes missing syntax highlighting for the code examples

    This reverts commit efd641ffab34e433a8d8a7d78914576f2425aa90.

    This changeset seems to be needed to suppress a warning on Ubuntu 20.04

    I guess there was a reason why the commit was reverted (maybe some CIs
    failed?), so try it again.

    suppress uninitialized variable warnings

    Starting GCC 7, warnings about uninitialized variables are issued around
    them.  Such warnings could be false positives (all versions of clang do
    not warn), but adding initializers there could never be bad things.

    tool/lib/test/unit: support TESTS='-- -ext-' again

    There is a test directory named test/-ext-.  Because this directry
    starts with a hyphen, we have to cheat test/unit in order for it to
    run the tests underneath.  TESTS='-- -ext' worked for a long time.
    Let's not break that maneuver.

    Run major GC to make sure the minor GC next time.

    `GC.start(full_mark: false)` can run full GC because of last
    GC status. Just after major GC, the possibility to run major GC
    next time is too small (not a zero, but too small possibility).

    send() has special method launcher in VM and it has special
    method_missing caller. This path doesn't set
    ec->method_missing_reason which is used at exception creation,
    so setup this information. Without this setting, NoMethodError
    exception becomes NameError.

    MiniTest::Unit (superclass of Test::Unit::Runner) does not has

    However some tests use MiniTest::Unit without setup of seed option
    and it cases unexpected test failures. To solve this issue, add
    default seed parameter 42.

    Use `$script_mode` instead of `$prog_mode` for gem inistallation.

    rbinstall is using `$script_mode` and `$prog_mode`. However, the
    `$script_mode` fallbacks to `$prog_mode` if not provided.

    However, RubyGems do not distinguish between `$script_mode` and
    `$prog_mode`:

    https://github.com/rubygems/rubygems/blame/92892bbc3adba86a90756c385433835f6761b8da/lib/rubygems/installer.rb#L196

    Comparing the usage of `$script_mode` and `$prog_mode`, it seems that
    the `$script_mode` should be used where RubyGems expects `$prog_mode`.

    Use `Gem::Package` like object instead of monkey patching.

    1. This is similar to what RubyGems does and it is less magic [[1]].
    2. It avoids deprecated code paths in RubyGems [[2]].

    prevent GC from mjit worker.

    ALLOC_N() can causes GC. Sometimes `mjit_copy_job_handler()`
    can be called by mjit_worker thread which is not a Ruby thread,
    so we need to prevent GC in this function. This patch has some
    issues, but I introduce it to pass the tests.

    test/readline - allow ENV control of test class creation

    In ruby/ruby, the tests run on both readline & reline by creating four test classes:
    ```
    TestReadline
    TestReadlineHistory

    TestRelineAsReadline
    TestRelineAsReadlineHistory
    ```

    Reline inports the test files and uses them in its CI.  Adding the ENV control allows it to only run the `TestRelineAsReadline` classes.

    Introduce disposable call-cache.

    This patch contains several ideas:

    (1) Disposable inline method cache (IMC) for race-free inline method cache
        * Making call-cache (CC) as a RVALUE (GC target object) and allocate new
          CC on cache miss.
        * This technique allows race-free access from parallel processing
          elements like RCU.
    (2) Introduce per-Class method cache (pCMC)
        * Instead of fixed-size global method cache (GMC), pCMC allows flexible
          cache size.
        * Caching CCs reduces CC allocation and allow sharing CC's fast-path
          between same call-info (CI) call-sites.
    (3) Invalidate an inline method cache by invalidating corresponding method
        entries (MEs)
        * Instead of using class serials, we set "invalidated" flag for method
          entry itself to represent cache invalidation.
        * Compare with using class serials, the impact of method modification
          (add/overwrite/delete) is small.
        * Updating class serials invalidate all method caches of the class and
          sub-classes.
        * Proposed approach only invalidate the method cache of only one ME.

    See [Feature #16614] for more details.

    VALUE size packed callinfo (ci).

    Now, rb_call_info contains how to call the method with tuple of
    (mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and
    mid+argc+flags only requires 64bits. So this patch packed
    rb_call_info to VALUE (1 word) on such cases. If we can not
    represent it in VALUE, then use imemo_callinfo which contains
    conventional callinfo (rb_callinfo, renamed from rb_call_info).

    iseq->body->ci_kw_size is removed because all of callinfo is VALUE
    size (packed ci or a pointer to imemo_callinfo).

    To access ci information, we need to use these functions:
    vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci).

    struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg.

    rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc()
    is temporary removed because cd->ci should be marked.

    comma at the end of enum is a C++11ism

    Comma at the end of enum is allowed in C since C99. We can use them
    internally.  However when it comes to extension libraries, they could be
    written in different C++ versions.  We cannot assume sometihng.  Public
    headers shall keep compatibilities.

    avoid defining inline

    Recent (since 2012 maybe?) MSVC ships a header named xkeycheck.h, which
    (kindly!) aborts compilation on redefinition of C++ keywords.  Let's not
    define this in case of C++.

    ext/-test-/cxxanyargs: prevent have_devel check

    The `cxx.try_compile` command in this file kicks `cxx.have_devel?`
    internally, which recursively calls `cxx.try_link` with a different
    source code.  We don't want that happen (the source code compiled in
    this file must be the first one).  We need to fake the system.

    `make leaked-globals` points out that this function is leaked.  This has
    not been detected in our CI because it is defined only when
    VM_CHECK_MODE is nonzero.

    Just make it static and everytihng goes well.

    [ruby/openssl] ts: simplify OpenSSL::Timestamp::Request#algorithm

    Stop the special treatment of invalid hashAlgorithm of the message
    imprint. Those invalid values can only appear after the object is
    instantiated, before the user sets an actual message digest algorithm.

    OpenSSL::Timestamp::TokenInfo#algorithm already does the same.

    Also, remove the test case "test_create_request" since it does not make
    much sense. Those fields are to be set by the user after creation of
    the object and checking the initial value is pointless.

    test/openssl/fixture/chain/server.key should be longer.
    It should be documented how to create the files.
    BTW, it would be a good idea to dynamically create a key during test
    instead of fixed files.

    Make OpenSSL::OSSL#test_memcmp_timing robust

    The test was too fragile.  Actually, it fails on one of our CIs
    immediately after it was merged to ruby/ruby.

    https://gist.github.com/ko1/7ea4a5826641f79e2f9e041d83e45dba#file-brlog-trunk_clang_40-20200216-101730-L532-L535

    * Two measurements, a-b and a-c, must be interative instead of
      sequential; the execution time will be easily affected by disturbance
      (say, cron job or some external process invoked during measurement)

    * The comparison of the two results must be relative instead of
      absolute; slow machine may take several tens of seconds for each
      execution, and one delta second is too small.  The test cases of a, b,
      and c are very extreme, so if the target method has a bug, the two
      execution times would be very different.  So I think it is enough to
      check if the difference is less than 10 times.

    This change is the same as https://github.com/ruby/openssl/pull/332

    Since 9d9aea7fe50f6340829faa105d9ffe08ebaee658, generic instance
    variables need `iv_index_tbl` in the object's class.  As hidden
    objects, however, have no class, access to the variables causes a
    segfault.  Get rid of that segfault by raising an exception, for
    the time being.

    Make yield in singleton class definitions in methods a SyntaxError

    This behavior was deprecated in 2.7 and scheduled to be removed
    in 3.0.

    Calling yield in a class definition outside a method is now a
    SyntaxError instead of a LocalJumpError, as well.

    This `str2` variable can be non-string (regexp etc.) but the previous
    code passed it directly to rb_enc_str_asciionly_p(), which expects its
    argument be a string.  Let's enforce that constraint.

    We were inefficient in cases where there are a lot of duplicates due to

    Clarified documentation in rb_integer_unpack [ci skip]

    I struggled figuring out which of the pack/unpack functions goes into which direction and the two first sentences were of the documentation were:
    * Import an integer into a buffer.
    * Export an integer into a buffer.

    It sounds like both of them go from a ruby integer to a buffer because both use "into". So I fixed it and went to "Import an integer from a buffer". I find this much more clear.

    [rubygems/rubygems] Fix require issue with file extension priority

    If `require "a"` is run when two folders have been specified in the -I
    option including a "a.rb" file and a "a.so" file respectively, the ruby
    spec says that the ".rb" file should always be preferred. However, the
    logic we added in https://github.com/rubygems/rubygems/commit/6b81076d9
    to make the -I option always beat default gems does not respect this
    spec, creating a difference from the original ruby-core's require.

    [the ruby spec says]: https://github.com/ruby/spec/blob/d80a6e2b221d4f17a8cadcac75ef950c59cba901/core/kernel/shared/require.rb#L234-L246

    [rubygems/rubygems] Allow releasing with a rubygems pre version

    This condition is too restrictive in my opinion. If a user has a pre
    version of rubygems installed, she should be fully responsible for it,
    and we shouldn't restrict any functionality.

    Also, why is a new prerelease disallowed but an old prelease allowed, or
    why is 2.0.0.rc2 explicitly whitelisted? I believe this kind of
    exceptions are one more reason to actually permit this.

    this ternary operator is an undefined behaviour

    Let me quote ISO/IEC 9899:2018 section 6.5.15:

    > Constraints
    >
    > The first operand shall have scalar type.
    > One of the following shall hold for the second and third operands:
    > — both operands have arithmetic type;
    > — both operands have the same structure or union type;
    > — both operands have void type;
    (snip)

    Here, `*option` is a const struct rb_compile_option_struct. OTOH
    `COMPILE_OPTION_DEFAULT` is a struct rb_compile_option_struct, without
    const.   These two are _not_ the "same structure or union type".  Hence
    the expression renders undefined behaviour.  COMPILE_OPTION_DEFAULT is
    not a const because `RubyVM::InstructionSequence.compile_option=`
    touches its internals on-the-fly.  There is no way to meet the
    constraints quoted above.

    Using ternary operator here was a mistake at the first place.  Let's
    just replace it with a normal `if` statement.

    fine-grained #ifdef guard for Sparc systems

    There are cases when sizeof(int) == sizeof(long) == sizeof(size_t).  On
    such cases however int and long are incompatible types in theory.  We
    should not assume typedef long size_t, because on Solaris size_t is
    actually a typedef of int.

    This reduces compiler warnings on such situations.

    do not assume GCC for __builtin_setjmp

    Namely recent Sun C compiler has this function, and is not a GCC.
    Meanwhile the code without RUBY_JMP_BUF assumes GCC.  We have to define
    the macro when we detect __builtin_setjmp for non-GCC compilers.

    declaration of PUREFUNC, not foo.

    `struct rb_scan_args_t::vargs` is never used

    Removed no longer used variable `last_hash`

    1. By substituting `n_var` with its initializer, `0 < n_var` is
       equivalent to `argc > argi + n_trail`.
    2. As `argi` is non-negative, so `argi + n_trail >= n_trail`, and
       the above expression is equivalent to `argc > n_trail`.
    3. Therefore, `f_last` is always false, and `last_hash` is no
       longer used.

    support C++ std::nullptr_t

    C++ keyword `nullptr` represents a null pointer (note also that NULL is
    an integer in C++ due to its design flaw).  Its type is `std::nullptr_t`,
    defined in <cstddef> standard header.  Why not support it when the
    backend implementation can take a null pointer as an argument.

    Ignore expected errors on compiling C++ source [Bug #16331]

    BSD make can run parallel more aggressively than GNU make. It communicate
    with other make process through -J option in MAKEFLAGS environment variable
    to notify a build failure happened in an other pararell make process.
    https://www.freebsd.org/cgi/man.cgi?make

    It usually works well but ext/-test-/cxxanyargs/Makefile has two targets
    which are expected to fail (failure.o and failurem1.o).

    Additional note:
    To test and debug this issue, following command will speed up it.
    `make -f exts.mk -j8 clean all`

    srand() should not run in tests.

    test_rand.rb calls srand() several times, however it change global
    rand-sequence (and --seeds doesn't have meaning). This patch makes
    such tests run in other processes.

    support multi-run for test/ruby/test_time.rb

    ruby/test_time_tz.rb (not sure only this file affects) changes TZ
    and it seems to change internal state. This internal state change
    fails test_2038 and test_timegm on 2nd time execution.

    At this time I have no idea how to fix this issue, so I skips these
    tests on 2nd trial.

    You can try this failure with the following command without this patch.

      $ make test-all TESTS='--repeat-count=2 ruby/require ruby/time ruby/time_tz'

    Do not autosplat when calling proc with empty keyword splat

    With the removal of the splatted argument when using an empty
    keyword splat, the autosplat code considered an empty keyword
    splat the same as no argument at all.  However, that results
    in autosplat behavior changing dependent on the content of
    the splatted hash, which is not what anyone would expect or
    want.  This change always skips an autosplat if keywords were
    provided.

    brace the fact that lchmod(2) can EOPNOTSUPP

    Musl libc has this function as a tiny wrapper of fchmodat(3posix).  On
    the other hand Linux kernel does not support changing modes of a symlink.
    The operation always fails with EOPNOTSUPP.  This fchmodat behaviour is
    defined in POSIX.  We have to take care of such exceptions.

    reroute musl unistd.h weirdness

    Musl is (of course) not glibc.  Its confstr(3) does not understand
    _CS_GNU_LIBC_VERSION.  That's fair.  Problem is, its unistd.h has that
    constant defined for unknown reason.  We cannot blindly say the libc is
    glibc by looking at it.  Instead we have to kick it, then see if it
    quacks like a duck.

    See https://git.musl-libc.org/cgit/musl/tree/include/unistd.h

    Musl is not named as libc.so.6 so the `ldd` hack implemented some lines

    Remove empty keyword splats when calling even when using ruby2_keywords

    Keeping empty keyword splats for ruby2_keywords methods was
    necessary in 2.7 to prevent the final positional hash being
    treated as keywords.  Now that keyword argument separation
    has been committed, the final positional hash is never
    treated as keywords, so there is no need to keep empty
    keyword splats when using ruby2_keywords.

    Fix pp when passed a empty ruby2_keywords-flagged hash as array element

    This causes problems because the hash is passed to a block not
    accepting keywords.  Because the hash is empty and keyword flagged,
    it is removed before calling the block.  This doesn't cause an
    ArgumentError because it is a block and not a lambda.  Just like
    any other block not passed required arguments, arguments not
    passed are set to nil.

    Issues like this are a strong reason not to have ruby2_keywords
    by default.

    This is a fix related to the following issue.
    rails/rails#33464

    Not only in rails apps, some little ruby app with only 2 or 3 ruby
    files reproduce the problem during many years.

    When I edit linux ruby files by vs code via samba on windows, and
    then I execute the ruby files on linux, "require_relative" will
    sometimes not work properly.

    My solution is to wait a monument if the required relative file is
    busy.

    Reline: Fix changed test results due to change to UTF-8 on Windows

    In commit f8ea2860b0cac1aec79978e6c44168802958e8af the Reline encoding
    for native windows console was changed to hardcoded UTF-8.
    This caused failures in reline and readline tests, but they were hidden,
    because parallel ruby tests incorrectly used Reline::ANSI as IOGate.
    Tests failures were raised in single process mode, but not with -j switch.

    This patch corrects encodings on native Windows console.

    Reline: Use a more robust detection of MinTTY

    The previous detection per get_screen_size fails when stdout is passed
    to a pipe. That is the case when running ruby tests in parallel ("-j" switch).
    In this case Reline believes that it's running on MinTTY and the tests
    are running with ANSI IOGate instead of the Windows adapter on MINGW.
    So parallel test results were different to that of a single process.
    This commit fixes these differences.

    The code is taken from git sources and translated to ruby.
    NtQueryObject() is replaced by GetFileInformationByHandleEx(), because
    NtQueryObject() is undocumented and is more difficult to use:

    [ruby/irb] Fix compatibility with rails before 5.2

    Rails before 5.2 added Array#append as an alias to Array#<< ,
    so that it expects only one argument.
    However ruby-2.5 added Array#append as an alias to Array#push
    which takes any number of arguments.

    If irb completion is used in `rails c` (for example "IO.<tab>")
    it fails with:
      irb/completion.rb:206:in `<<': wrong number of arguments (given 3, expected 1) (ArgumentError)

    Using Array#push instead of Array#append fixes compatibility.

    It was found that a feature to check and add ruby2_keywords flag to an

    It is possible to do the same without explicit APIs, but it would be
    good to provide them as a core feature.

    marshal.c: Support dump and load of a Hash with the ruby2_keywords flag

    It is useful for a program that dumps and load arguments (like drb).
    In future, they should deal with both positional arguments and keyword
    ones explicitly, but until ruby2_keywords is deprecated, it is good to
    support the flag in marshal.

    The implementation is similar to String's encoding; it is dumped as a
    hidden instance variable.

    [ruby/irb] Fix crashing when multiple open braces per line

    https://github.com/ruby/irb/issues/55

    If we had put multiple open braces on a line the with no closing brace
    spaces_of_nest array keeps getting '0' added to it. This means that when
    we pop off of this array we are saying that we should be in position zero
    for the next line. This is an issue because we don't always want to be
    in position 0 after a closing brace.

    Example:
    ```
    [[[
    ]
    ]
    ]
    ```
    In the above example the 'spaces_of_nest' array looks like this after
    the first line is entered: [0,0,0]. We really want to be indented 4
    spaces for the 1st closing brace 2 for the 2nd and 0 for the 3rd. i.e.
    we want it to be: [0,2,4].

    We also saw this issue with a heredoc inside of an array.

    ```
    [<<FOO]
    hello
    FOO
    ```

    [ruby/irb] Fix newline depth with multiple braces

    This commit fixes the check_newline_depth_difference method to multiple
    open braces on one line into account. Before this change we were
    subtracting from the depth in check_newline_depth_difference on
    every open brace. This is the right thing to do if the opening and
    closing brace are on the same line. For example in a method definition we
    have an opening and closing parentheses we want to add 1 to our depth,
    and then remove it.

    ```
    def foo()
    end
    ```

    However this isn't the correct behavior when the brace spans multiple
    lines. If a brace spans multiple lines we don't want to subtract from
    check_newline_depth_difference and we want to treat the braces the same
    way as we do `end` and allow check_corresponding_token_depth to pop the
    correct depth.

    Example of bad behavior:

    ```
    def foo()
      [
      ]
    puts 'bar'
    end
    ```

    Example of desired behavior:

    ```
    def foo()
      [
      ]
      puts 'bar'
    end
    ```

    then checked out in CRLF mode.  Cygwin sed doesn't consider the CR
    a part of EOL code, though.

    reload AR table body for transient heap.

    ar_talbe (Hash representation for <=8 size) can use transient heap
    and the memory area can move. So we need to restore `pair' ptr after
    `func` call (which can run any programs) because of moving.

    avoid undefined behaviour when n==0

    ISO/IEC 9899:1999 section 6.5.7 states that "If the value of the right
    operand is negative or is greater than or equal to the width of the
    promoted left operand, the behavior is undefined".  So we have to take
    care of such situations.

    This has not been a problem because contemporary C compilers are
    extraordinary smart to compile the series of shifts into a single
    ROTLQ/ROTRQ machine instruction.  In contrast to what C says those
    instructions have fully defined behaviour for all possible inputs.
    Hence it has been quite difficult to observe the undefined-ness of such
    situations.  But undefined is undefined.  We should not rely on such
    target-specific assumptions.

    We are fixing the situation by carefully avoiding shifts with out-of-
    range values.  At least GCC since 4.6.3 and Clang since 8.0 can issue
    the exact same instructions like before the changeset.

    Also in case of Intel processors, there supposedly be intrinsics named
    _rotr/_rotl that do exactly what we need.  They, in practice, are absent
    on Clang before 9.x so we cannot blindly use.  But we can at least save
    MSVC.

    more use of MSC_VERSION_SINCE

    Replaces `#ifdef _MSC_VER` with more accurate version checks.  Also,
    `defined(_WIN64) && defined(__AVX2__)` is redundant because there is no

    always expand ivar arrays to max width

    If the instance variable table hasn't been "expanded", allocate the
    maximum size of the ivar table.  This operates under the assumption that
    most objects will eventually expand their ivar array to the maximum
    width anyway, so we may as well avoid realloc calls.

    Call initialize_clone with freeze: false if clone called with freeze: false

    This makes it possible to initialize_clone to correctly not freeze
    internal state if the freeze: false keyword is passed to clone.

    If clone is called with freeze: true or no keyword, do not pass
    a second argument to initialize_clone to keep backwards
    compatibility.

    This makes it so that external libraries that override
    initialize_clone but do not support the freeze keyword will fail
    with ArgumentError if passing freeze: false to clone.  I think that
    is better than the current behavior, which succeeds but results in
    an unfrozen object with frozen internals.

    Fix related issues in set and delegate in stdlib.

    Fully separate positional arguments and keyword arguments

    This removes the warnings added in 2.7, and changes the behavior
    so that a final positional hash is not treated as keywords or
    vice-versa.

    To handle the arg_setup_block splat case correctly with keyword
    arguments, we need to check if we are taking a keyword hash.
    That case didn't have a test, but it affects real-world code,
    so add a test for it.

    This removes rb_empty_keyword_given_p() and related code, as
    that is not needed in Ruby 3.  The empty keyword case is the
    same as the no keyword case in Ruby 3.

    This changes rb_scan_args to implement keyword argument
    separation for C functions when the : character is used.
    For backwards compatibility, it returns a duped hash.
    This is a bad idea for performance, but not duping the hash
    breaks at least Enumerator::ArithmeticSequence#inspect.

    Instead of having RB_PASS_CALLED_KEYWORDS be a number,
    simplify the code by just making it be rb_keyword_given_p().

    disable ccache if $CC is in /usr/lib/ccache/$CC.

    MJIT with ccache has a problem on docker environment, so
    we need to use original CC (/usr/bin/gcc, for example).
    Ubuntu system provides /usr/lib/ccache/gcc and so on to use
    gcc with ccache. It is easy to setup ccache by adding
    /usr/lib/ccache to $PATH. However we need to use /usr/bin/gcc
    (and so on) for MJIT_CC. We can specify MJIT_CC option at
    configure, but specifying them is troublesome.

    This patch choose original $CC (/usr/bin/gcc, for example)
    if $CC is /usr/lib/ccache/$CC.

    For the most common cases of `rotate!` one place to the right or to the
    left, instead of doing some reversals of the array we just keep a single
    value in a temporary value, use memmove and then put the temporary
    value where it should be.

    Use __func__ as rb_cv_function_name_string on OpenBSD

    The use of RUBY_WERROR_FLAG causes this test to fail on OpenBSD
    platforms that use the binutils linker (ld.bfd) instead of the
    llvm linker (ld.lld), due to warnings added to the binutils linker
    in OpenBSD.

    Removing the RUBY_WERROR_FLAG would probably also fix it, but that
    would affect other platforms.

    This should also be backported to Ruby 2.7.

    Analysis and similar fix recommended by George Koehler.

    OpenBSD is the only platform that uses this support by default,

    decouple internal.h headers

    Saves comitters' daily life by avoid #include-ing everything from
    internal.h to make each file do so instead.  This would significantly
    speed up incremental builds.

    We take the following inclusion order in this changeset:

    1.  "ruby/config.h", where _GNU_SOURCE is defined (must be the very
        first thing among everything).
    2.  RUBY_EXTCONF_H if any.
    3.  Standard C headers, sorted alphabetically.
    4.  Other system headers, maybe guarded by #ifdef
    5.  Everything else, sorted alphabetically.

    Exceptions are those win32-related headers, which tend not be self-
    containing (headers have inclusion order dependencies).

    assume C99

    Now that we no longer support old compilers, we can safely delete
    several obsolete #ifdef gurads.  Also because (as of writing) it is
    impossible to compile the program using C++ compilers, lets just
    entirely prohibit __cplusplus to reduce # of LOCs.

    Note however that we still cannot eliminate __STDC_VERSION__ checks,
    because MSVC does not define it, saying its C99 support is partial.

    re-add io.h and encoding.h into internal.h

    This is tentative.  For the sake of simplicity we partially revert
    commits e9cb552ec96, ee85a6e72b and 51edb300425.  Will decouple them
    once again when we are ready.

    split internal.h into files

    One day, I could not resist the way it was written.  I finally started
    to make the code clean.  This changeset is the beginning of a series of
    housekeeping commits.  It is a simple refactoring; split internal.h into
    files, so that we can divide and concur in the upcoming commits.  No
    lines of codes are either added or removed, except the obvious file
    headers/footers.  The generated binary is identical to the one before.
