The test disables GC but never reenables it. Before this patch, running
all tests would have a peak RSS in the main process of >4GB. After this
patch, peak RSS in the main process is <500MB.
If the thread termination invokes user code after `th->status` becomes
`THREAD_KILLED`, and the user unblock function causes that `th->status` to
become something else (e.g. `THREAD_RUNNING`), threads waiting in
`thread_join_sleep` will hang forever. We move the unblock function call
to before the thread status is updated, and allow threads to join as soon
as `th->value` becomes defined.
This reverts commit 6505c77501.
This speeds up performance by multiple orders of magnitude for
large integers.

This changes Thread::Location::Backtrace#absolute_path to return
nil for methods/procs defined in eval. If the realpath of an iseq
is nil, that indicates it was defined in eval, in which case you
cannot use RubyVM::AbstractSyntaxTree.of.

This fixes cases where exceptions raised using Thread#raise are
swallowed by finalizers and not delivered to the running thread.
This could cause issues with finalizers that rely on pending interrupts,
but that case is expected to be rarer.

The existing implementation of `Net::HTTP#write_timeout` relies on
`Net::BefferedIO` to trigger the `Net::WriteTimeout` error. This commit
changes `send_request_with_body_stream` to remove the optimization that
was making `Net::HTTP#write_timeout` not work when `body_stream` is
used.

The test fails on Solaris 10. Maybe due to the IPv6 configuration on the
server, but I have no idea at all. I've asked @ngoto to investigate the
issue, so will tentatively skip the tests on Solaris

`vm_opt_method_table` is me=>bop table to manage the optimized
methods (by specialized instruction). However, `me` can be invalidated
to invalidate the method cache entry.
[Bug #17725]
To solve the issue, use `me-def` instead of `me` which simply copied
at invalidation timing.

I'm not sure whether this handles all multithreaded use cases,
but this handles the example that crashes almost immediately
and does 10,000,000 total deflates using 100 separate threads.
To prevent the tests from taking forever, the committed test
for this uses only 10,000 deflates across 10 separate threads,
which still causes a segfault in the previous implementation
almost immediately.

This reverts commit 13f8521c63.

This revert is to confirm whether the commit is the cause.
If the failures consistently occur after this revert, I'll
reintroduce the commit.
The previous implementation could result in a returned
float that is 1/(10**ndigits) too low. First try adding
one before dividing, and if that results in a value that is
greater than the initial number, then try the original
calculation.
Spec added for ciel, but the issue doesn't appear to affect
ciel, at least not for the same number. If the issue does
effect ciel, a similar fix could probably work for it.

VM patch from wanabe.
Test based on example from buzztaiki (Taiki Sugawara).
Test fails when compiles with -DRUBY_DEBUG, as that can
can use rb_bug instead of NoMemoryError, which doesn't
allow testing this case. Test also fails on MingW, as
RangeError is used instead of NoMemoryError. Skip the
test in either case.
Fixes [Bug #15779]
Deal with the issue that the emoji files in emoji/13.1 have Unicode
Emoji version 13.1, but at the same time the files in 13.0.0/ucd/emoji
are still at Emoji version 13.0. Specifically:
- Add a version attribute to TestEmojiBreaks::BreakFile
- Take the version for emoji-variant-sequences.txt from the Unicode
version, removing the last two characters.
- Improve information in exceptions for file name and version mismatches.
* Using a module to map scheme name to scheme class, which also works with Ractor.
* No constant redefinition, no ObjectSpace, still fast lookup for initial schemes.
