The spinlock here performs poorly when there are multiple Ractors. The
improvement on single threaded performance doesn't seem that
significant, so I think we should just use malloc.
[Bug #21214]
If we allocate objects where one heap holds transient objects and another
holds long lived objects, then the heap with transient objects will grow
along the heap with long lived objects, causing higher memory usage.
For example, we can see this issue in this script:
def allocate_small_object = []
def allocate_large_object = Array.new(10)
arys = Array.new(1_000_000) do
# Allocate 10 small transient objects
10.times { allocate_small_object }
# Allocate 1 large object that is persistent
allocate_large_object
end
pp GC.stat
pp GC.stat_heap
Before this change:
heap_live_slots: 2837243
{0 =>
{slot_size: 40,
heap_eden_pages: 1123,
heap_eden_slots: 1838807},
2 =>
{slot_size: 160,
heap_eden_pages: 2449,
heap_eden_slots: 1001149},
}
After this change:
heap_live_slots: 1094474
{0 =>
{slot_size: 40,
heap_eden_pages: 58,
heap_eden_slots: 94973},
2 =>
{slot_size: 160,
heap_eden_pages: 2449,
heap_eden_slots: 1001149},
}
`Integer.sqrt` uses `sqrt(3)` from libm for small values.
This method must return a value less than or equal to the actual integer
square root, but libm's sqrt does not always guarantee that.
This change corrects that by decrementing the result if necessary.
Fixes [Bug #21217]
Using `rb_obj_clone` introduce other problems, such as `initialize_*`
callbacks invocation in the context of the parent ractor.
So we can revert back to copy the content of the object slots,
but in a way that is aware of size pools.
* Explicitly recommend copying full command output and not just the bug
report template part.
* Include quadruple quotes in the "What actually happened section" and
tell users to copy full command output inside. Hopefully quadruple
quotes will make the error report information (which includes triple
quotes itself) render fine by default.
* Avoid "actually" as per quality_spec.rb recommendation.

The test case test_split_content fails on RHEL 9 and Fedora 41 because
their OpenSSL packages do not accept SHA-1 signatures. This was only
caught after commit 69fd7f8863 added the missing assertion.
While the example PKCS#7 structures could be simply regenerated with
SHA-256, this test case could be simplified because it is checking two
different things.
Replace test_split_content with separate test cases: one verifying
signed-data authenticatedAttributes and another for decoding BER input.

In 307732ccee Ractors were changed to
explicitly run GC when the first non-main one was activated in order to
disable the transient heap. Theap no longer exists so I don't think we
need to do this.
When calling a method that accepts an anonymous splat and literal
keywords without any arguments, an assertion failure was previously
raised. Set rest_index to 0 when setting rest to the frozen hash,
so the args_argc calculation is accurate.
While here, add more tests for methods with anonymous splats with
and without keywords and keyword splats to confirm behavior is
correct.
Also add a basic bootstrap test that would hit the previous assertion
failure.

Because it ends up treating it as a local variable, and `a.x`
is not a valid local variable name.
I'm not big on pattern matching, but conceptually it makes sense to me
to treat anything inside ^() to not be
pattern matching syntax?

Documented the necessity of calling `wait` in a loop. We modified the
example to demonstrate the idiomatic use, and added a third thread `a2`
to demonstrate another reason that necessitates the loop.
Mentioned spurious wake-up in the doc.
[Bug #21211]
Socket errors raised from background threads are hard to track down because
their backtrace starts from the spawned thread.
To solve this we can raise a new error with the old one as `cause`.
