2025-07-21Introduce free function to rb_concurrent_set_funcsPeter Zhu
If we create a key but don't insert it (due to other Ractor winning the race), then it would leak memory if we don't free it. This introduces a new function to free that memory for this case.

2025-07-07Rename `ractor_safe_set` into `concurrent_set`Jean Boussier
There's nothing ractor related in them, and the classic terminology for these sort of data structures is `concurrent-*`, e.g. concurrent hash.

2025-06-27Extract Ractor safe table used for frozen stringsPeter Zhu
This commit extracts the Ractor safe table used for frozen strings into ractor_safe_table.c, which will allow it to be used elsewhere, including for the global symbol table.
2025-06-25Get String#crypt working with multi-ractor in cases where !HAVE_CRYPT_RLuke Gruber
In commit 12f7ba5ed4a, ractor safety was added to String#crypt, however in certain cases it can cause a deadlock. When we lock a native mutex, we cannot allocate ruby objects because they might trigger GC which starts a VM barrier. If the barrier is triggered and other native threads are waiting on this mutex, they will not be able to be woken up in order to join the barrier. To fix this, we don't allocate ruby objects when we hold the lock. The following could reproduce the problem: ```ruby strings = [] 10_000.times do |i| strings << "my string #{i}" end STRINGS = Ractor.make_shareable(strings) rs = [] 100.times do rs << Ractor.new do STRINGS.each do |s| s.dup.crypt(s.dup) end end end while rs.any? r, obj = Ractor.select(*rs) rs.delete(r) end ``` I will not be adding tests because I am almost finished a PR to enable running test-all test cases inside many ractors at once, which is how I found the issue.

2025-06-24Reduce exposure of FL_FREEZEJean Boussier
The `FL_FREEZE` flag is redundant with `SHAPE_ID_FL_FROZEN`, so ideally it should be eliminated in favor of the later. Doing so would eliminate the risk of desync between the two, but also solve the problem of the frozen status being global in namespace context (See Bug #21330).

2025-06-13Get rid of FL_EXIVARJean Boussier
Now that the shape_id gives us all the same information, it's no longer needed. Notes: Merged: https://github.com/ruby/ruby/pull/13612
2025-06-13Use the `shape_id` rather than `FL_EXIVAR`Jean Boussier
We still keep setting `FL_EXIVAR` so that `rb_shape_verify_consistency` can detect discrepancies. Notes: Merged: https://github.com/ruby/ruby/pull/13612
2025-06-13Add SHAPE_ID_HAS_IVAR_MASK for quick ivar checkJean Boussier
This allow checking if an object has ivars with just a shape_id mask. Notes: Merged: https://github.com/ruby/ruby/pull/13606
