2025-10-29Fix memory leak in String#encode when fallback too bigPeter Zhu
The following script leaks memory: 10.times do 100_000.times do "\ufffd".encode(Encoding::US_ASCII, fallback: proc { "\uffee" }) rescue end puts `ps -o rss= -p #{$$}` end Before: 451196 889596 1328252 1766524 2204668 2643068 3081724 3520124 3958524 4396796 After: 12800 13056 13184 13312 13312 13312 13312 13312 13312 13312

2025-10-28ZJIT: Call test again after profiling itTakashi Kokubun

2025-10-28ZJIT: Specialize Array#pop for no argument case (#14933)Aiden Fox Ivey
Fixes https://github.com/Shopify/ruby/issues/814 This change specializes the case of calling `Array#pop` on a non frozen array with no arguments. `Array#pop` exists in the non-inlined C function list in the ZJIT SFR performance burndown list. If in the future it is helpful, this patch could be extended to support the case where an argument is provided, but this initial work seeks to elide the ruby frame normally pushed in the case of `Array#pop` without an argument.
2025-10-27Correctly compile splats in for-loop index in prismEarlopain
Fixes [Bug #21648] This is a followup to https://github.com/ruby/ruby/pull/13597. The added test passed but didn't emit the same instructions. This also handles bare splats and aligns instructions for all cases
2025-10-27Fix segfault when moving nested objects between ractors during GCJoshua Young
Fixes a segmentation fault when moving nested objects between ractors with GC stress enabled and YJIT. The issue is a timing problem: `move_enter` allocates new object shells but leaves their contents uninitialized until `move_leave` copies the actual data. If GC runs between these steps (which GC stress makes likely), it tries to follow what appear to be object pointers but are actually uninitialized memory, encountering null or invalid addresses. The fix zero-initializes the object contents immediately after allocation in `move_enter`, ensuring the GC finds safe null pointers instead of garbage data. The crash reproduced most consistently with nested hashes and YJIT, likely because nested structures create multiple uninitialized objects simultaneously while YJIT's memory usage increases the probability of GC triggering during moves.

2025-10-24Fix memory leak of transcoding when fallback raisesPeter Zhu
When the fallback function in transcode_loop raises, it will leak the memory in rb_econv_t. The following script reproduces the leak: 10.times do 100_000.times do "\ufffd".encode(Encoding::US_ASCII, fallback: proc { raise }) rescue end puts `ps -o rss= -p #{$$}` end Before: 451196 889980 1328508 1767676 2206460 2645372 3083900 3522428 3960956 4399484 After: 12508 12636 12892 12892 13148 13404 13532 13788 13916 13916
2025-10-23ZJIT: Add tests for non-leaf classvar get and set (#14924)Daniel Colson
This commit adds tests that raise on `getclassvariable` and `setclassvariable` to exercise the non-leaf cases as suggested in https://github.com/ruby/ruby/pull/14918#discussion_r2453804603
2025-10-22ZJIT: Implement classvar get and set (#14918)Daniel Colson
https://github.com/Shopify/ruby/issues/649 Class vars are a bit more involved than ivars, since we need to get the class from the cref, so this calls out to `rb_vm_getclassvariable` and `rb_vm_setclassvariable` like YJIT.

I tried to fix this by checking whether the two previous instructions are labeled.

2025-10-02ZJIT: Add `NoSingletonClass` patch point (#14680)Stan Lo
* ZJIT: Add NoSingletonClass patch point This patch point makes sure that when the object has a singleton class, the JIT code is invalidated. As of now, this is only needed for C call optimization. In YJIT, the singleton class guard only applies to Array, Hash, and String. But in ZJIT, we may optimize C calls from gems (e.g. `sqlite3`). So the patch point needs to be applied to a broader range of classes. * ZJIT: Only generate NoSingletonClass guard when the type can have singleton class * ZJIT: Update or forget NoSingletonClass patch point when needed

2025-09-25Properly unlock locked mutexes on thread cleanup.Luke Gruber
Mutexes were being improperly unlocked on thread cleanup. This bug was introduced in 050a8954395. We must keep a reference from the mutex to the thread, because if the fiber is collected before the mutex is, then we cannot unlink it from the thread in `mutex_free`. If it's not unlinked from the the thread when it's freed, it causes bugs in `rb_thread_unlock_all_locking_mutexes`. We now mark the fiber when a mutex is locked, and the thread is marked as well. However, a fiber can still be freed in the same GC cycle as the mutex, so the reference to the thread is still needed. The reason we need to mark the fiber is that `mutex_owned_p()` has an ABA issue where if the fiber is collected while it's locked, a new fiber could be allocated at the same memory address and we could get false positives.

call-seq: Ractor.sharable_proc(self: nil){} -> sharable proc It returns shareable Proc object. The Proc object is shareable and the self in a block will be replaced with the value passed via `self:` keyword. In a shareable Proc, the outer variables should * (1) refer shareable objects * (2) be not be overwritten ```ruby a = 42 Ractor.shareable_proc{ p a } #=> OK b = 43 Ractor.shareable_proc{ p b; b = 44 } #=> Ractor::IsolationError because 'b' is reassigned in the block. c = 44 Ractor.shareable_proc{ p c } #=> Ractor::IsolationError because 'c' will be reassigned outside of the block. c = 45 d = 45 d = 46 if cond Ractor.shareable_proc{ p d } #=> Ractor::IsolationError because 'd' was reassigned outside of the block. ``` The last `d`'s case can be relaxed in a future version. The above check will be done in a static analysis at compile time, so the reflection feature such as `Binding#local_varaible_set` can not be detected. ```ruby e = 42 shpr = Ractor.shareable_proc{ p e } #=> OK binding.local_variable_set(:e, 43) shpr.call #=> 42 (returns captured timing value) ``` Ractor.sharaeble_lambda is also introduced.

2025-09-23gc_validate_pc(): Exclude imemos, add a test and explain the assertsAlan Wu
The validation is relevant only for traceable userland ruby objects ruby code could interact with. ZJIT's use of rb_vm_method_cfunc_is() allocates a CC imemo and was failing this validation when it was actually fine. Relax the check.

2025-09-22ZJIT: Refactor NewRangeFixnum (#14607)André Luiz Tiago Soares
## Context #14409 https://github.com/ruby/ruby/pull/14409#discussion_r2350238583 >You may have noticed that this doesn't produce a New range instruction. For that you probably need to use a local variable (makes it harder for the bytecode compiler to reason about, but the JIT sees through it). If you have time, please rewrite these tests. https://github.com/ruby/ruby/pull/14409#discussion_r2350240389 >There's some code above to do this for you: see arguments_likely_fixnums and coerce something or other ## Changes ### Refactor tests Modify tests force the usage of `NewRangeFixnum` instruction and make tests names more consistent. ### Refactor optimize ranges Didn't found `arguments_likely_fixnums` to be applicable unless we enable profiling for `NewRange` and change the criteria of when the optimization fires. But there were other ways to clean up the code. Simplify the logic and move it to `type_specialize`. Deleted the standalone `optimize_ranges` function.

2025-09-19ZJIT: Fix opt_{hash,ary,str}_{freeze,uminus}Max Bernstein
The stack layout is incompatible with the way we reify the stack for generating fallback SendWithoutBlock: the receiver is an embedded VALUE in the bytecode, not on the stack. Since we don't expect these to be overridden often, instead of fussing about with the stack layout, just hope for the best and PatchPoint/SideExit. Fix https://github.com/Shopify/ruby/issues/760
2025-09-18ZJIT: Compile sendforward with dynamic dispatch (#14501)Takashi Kokubun
* ZJIT: Compile sendforward with dynamic dispatch * Reload locals only if it has blockiseq * Add a test case of ... with other args
2025-09-18ZJIT: Support variadic C calls (#14575)Stan Lo
* ZJIT: Support variadic C calls This reduces the `dynamic_send_count` in `liquid-render` by ~21% * ZJIT: Reuse gen_push_frame * ZJIT: Avoid optimizing variadic C call when tracing is enabled
2025-09-18Remove test causing warningÉtienne Barrié
The test is no longer useful since 5c7dfe85a1dc49334e2828791f0ade42eee662db because Module#initialize_copy is empty/not defined anymore.
