2023-03-21YJIT: Fix deadlock in tests due to pipe capacityAlan Wu
Previously, when there is enough stats that the child process fills up the pipe capacity, the child process would block, with the parent process waiting forever as no one is reading to clear up the pipe. The test timed out in these situations. Use a separate thread in the parent to read from the pipe to unblock the child in these situation. EnvUtil also does this for handling stdout and stderr. I had the test suite deadlock on a Linux VM. Notes: Merged: https://github.com/ruby/ruby/pull/7578 Merged-By: XrXr

2023-03-20Use an st table for "too complex" objectsAaron Patterson
st tables will maintain insertion order so we can marshal dump / load objects with instance variables in the same order they were set on that particular instance [ruby-core:112926] [Bug #19535] Co-Authored-By: Jemma Issroff <jemmaissroff@gmail.com> Notes: Merged: https://github.com/ruby/ruby/pull/7560
2023-03-20Cache `Process.pid`Jean Boussier
[Feature #19443] It's not uncommon for database client and similar network libraries to protect themselves from Process.fork by regularly checking Process.pid Until recently most libc would cache `getpid()` so this was a cheap check to make. However as of glibc version 2.25 the PID cache is removed and calls to `getpid()` always invoke the actual system call which significantly degrades the performance of existing applications. The reason glibc removed the cache is that some libraries were bypassing `fork(2)` by issuing system calls themselves, causing stale cache issues. That isn't a concern for Ruby as bypassing MRI's primitive for forking would render the VM unusable, so we can safely cache the PID. Notes: Merged: https://github.com/ruby/ruby/pull/7326

2023-03-18Fix frozen status loss when moving objectsPeter Zhu
[Bug #19536] When objects are moved between size pools, their frozen status is lost in the shape. This will cause the frozen check to be bypassed when there is an inline cache. For example, the following script should raise a FrozenError, but doesn't on Ruby 3.2 and master. class A def add_ivars @a = @b = @c = @d = 1 end def set_a @a = 10 end end a = A.new a.add_ivars a.freeze b = A.new b.add_ivars b.set_a # Set the inline cache in set_a GC.verify_compaction_references(expand_heap: true, toward: :empty) a.set_a Notes: Merged: https://github.com/ruby/ruby/pull/7553

2023-03-17ObjectSpace::WeakMap: clean inverse reference when an entry is re-assignedJean Boussier
[Bug #19531] ```ruby wmap[1] = "A" wmap[1] = "B" ``` In the example above, we need to remove the `"A" => 1` inverse reference so that when `"A"` is GCed the `1` key isn't deleted. Notes: Merged: https://github.com/ruby/ruby/pull/7540

This reverts commit cae4342dd559e34c1ce6219593f77f0ad80286da. This is failing a lot of CIs and nobody is actively looking into fixing it. Let me revert this until we have a solution to it.
2023-03-16Add thread and ractor counts to bug reportsAlan Wu
This is useful for crash triaging. It also helps to hint extension developers about the misuse of `rb_thread_call_without_gvl()`. Example: $ ./miniruby -e 'Ractor.new{Ractor.receive}; Thread.new{sleep}; Process.kill:SEGV,Process.pid' <snip> -- Threading information --------------------------------------------------- Total ractor count: 2 Ruby thread count for this ractor: 2 Notes: Merged: https://github.com/ruby/ruby/pull/7532

2023-03-14Fix crash during compactionPeter Zhu
[Bug #19529] The fix for [Bug #19529] in commit 548086b contained a bug that crashes on the following script: ``` wm = ObjectSpace::WeakMap.new obj = Object.new 100.times do wm[Object.new] = obj GC.start end GC.compact ```
2023-03-14ObjectSpace::WeakMap: fix compaction supportJean Boussier
[Bug #19529] `rb_gc_update_tbl_refs` can't be used on `w->obj2wmap` because it's not a `VALUE -> VALUE` table, but a `VALUE -> VALUE *` table, so we need some dedicated iterator. Notes: Merged: https://github.com/ruby/ruby/pull/7518

2023-03-10Revert "Allow classes and modules to become too complex"Aaron Patterson
This reverts commit 69465df4242f3b2d8e55fbe18d7c45b47b40a626.
2023-03-10Revert and refine tests for uninitialized queueNobuyoshi Nakada
`Queue` and `SizedQueue` still check array members. Only the test of `ConditionVariable` is useless.
2023-03-10Remove stale testsNobuyoshi Nakada
These tests were added at a198bb3929a4562a12b4aa245a297c7d3695149f, when these classes were `Struct`s. Since these classes have been rewritten, these tests no longer make sense.

2023-02-27YJIT: Detect and reject `send(:alias_for_send, :foo)`Alan Wu
Previously, YJIT failed to put the stack into the correct shape when `BasicObject#send` calls an alias method for the send method itself. This can manifest as strange `NoMethodError`s in the final non-send receiver, as [seen][1] with the kt-paperclip gem. I also found a case where it makes YJIT fail the stack size assertion while compiling `leave`. YJIT's `BasicObject#__send__` implementation already rejects sends to `send`, but didn't detect sends to aliases of `send`. Adjust the detection and reject these cases.
