Check whether the current or previous frame is a Ruby frame in call_trace_func and rb_tracearg_binding before attempting to create a binding for the frame.

2021-12-10`TracePoint.allow_reentry`Koichi Sasada
In general, while TracePoint callback is running, other registerred callbacks are not called to avoid confusion by reentrace. This method allow the reentrace. This method should be used carefully, otherwize the callback can be easily called infinitely.

2021-12-01Rework tracing for blocks running as methodsAlan Wu
The main impetus for this change is to fix [Bug #13392]. Previously, we fired the "return" TracePoint event after popping the stack frame for the block running as method (BMETHOD). This gave undesirable source location outputs as the return event normally fires right before the frame going away. The iseq for each block can run both as a block and as a method. To accommodate that, this commit makes vm_trace() fire call/return events for instructions that have b_call/b_return events attached when the iseq is running as a BMETHOD. The logic for rewriting to "trace_*" instruction is tweaked so that when the user listens to call/return events, instructions with b_call/b_return become trace variants. To continue to provide the return value for non-local returns done using the "return" or "break" keyword inside BMETHODs, the stack unwinding code is tweaked. b_return events now provide the same return value as return events for these non-local cases. A pre-existing test deemed not providing a return value for these b_return events as a limitation. This commit removes the checks for call/return TracePoint events that happen when calling into BMETHODs when no TracePoints are active. Technically, migrating just the return event is enough to fix the bug, but migrating both call and return removes our reliance on `VM_FRAME_FLAG_FINISH` and re-entering the interpreter when the caller is already in the interpreter.

2021-11-22Avoid assert failure when NULL EC is expectedAlan Wu
After 5680c38c75aeb5cbd219aafa8eb48c315f287d97, postponed job APIs now expect to be called on native threads not managed by Ruby and handles getting a NULL execution context. However, in debug builds the change runs into an assertion failure with GET_EC() which asserts that EC is non-NULL. Avoid the assertion failure by passing `false` for `expect_ec` instead as the intention is to handle when there is no EC. Add a test from John Crepezzi and John Hawthorn to exercise this situation. See GH-4108 See GH-5094 [Bug #17573] Co-authored-by: John Hawthorn <john@hawthorn.email> Co-authored-by: John Crepezzi <john.crepezzi@gmail.com> Notes: Merged: https://github.com/ruby/ruby/pull/5156 Merged-By: XrXr
2021-11-09Use valid `ec` for postponed job.Koichi Sasada
Postponed job can be registered from non-Ruby thread, which means `ec` in TLS can be NULL. In this case, use main thread's `ec` instead. See https://github.com/ruby/ruby/pull/4108 and https://github.com/ruby/ruby/pull/4336 Notes: Merged: https://github.com/ruby/ruby/pull/5094
2021-10-26[Bug #18264] Fix memory leak in TracePointPeter Zhu
TracePoint leaks memory because it allocates a `rb_tp_t` struct without ever freeing it (it is created with `RUBY_TYPED_NEVER_FREE`). Notes: Merged: https://github.com/ruby/ruby/pull/5008
2021-10-20Put YJIT into a single compilation unitAlan Wu
For upstreaming, we want functions we export either prefixed with "rb_" or made static. Historically we haven't been following this rule, so we were "leaking" a lot of symbols as `make leak-globals` would tell us. This change unifies everything YJIT into a single compilation unit, yjit.o, and makes everything unprefixed static to pass `make leak-globals`. This manual "unified build" setup is similar to that of vm.o. Having everything in one compilation unit allows static functions to be visible across YJIT files and removes the need for declarations in headers in some cases. Unnecessary declarations were removed. Other changes of note: - switched to MJIT_SYMBOL_EXPORT_BEGIN which indicates stuff as being off limits for native extensions - the first include of each YJIT file is change to be "internal.h" - undefined MAP_STACK before explicitly redefining it since it collide's with a definition in system headers. Consider renaming?

2021-10-20TracePoint supportAlan Wu
This change fixes some cases where YJIT fails to fire tracing events. Most of the situations YJIT did not handle correctly involves enabling tracing while running inside generated code. A new operation to invalidate all generated code is added, which uses patching to make generated code exit at the next VM instruction boundary. A new routine called `jit_prepare_routine_call()` is introduced to facilitate this and should be used when generating code that could allocate, or could otherwise use `RB_VM_LOCK_ENTER()`. The `c_return` event is fired in the middle of an instruction as opposed to at an instruction boundary, so it requires special handling. C method call return points are patched to go to a fucntion which does everything the interpreter does, including firing the `c_return` event. The generated code for C method calls normally does not fire the event. Invalided code should not change after patching so the exits are not clobbered. A new variable is introduced to track the region of code that should not change.

2021-08-29Support tracing of attr_reader and attr_writerJeremy Evans
In vm_call_method_each_type, check for c_call and c_return events before dispatching to vm_call_ivar and vm_call_attrset. With this approach, the call cache will still dispatch directly to those functions, so this change will only decrease performance for the first (uncached) call, and even then, the performance decrease is very minimal. This approach requires that we clear the call caches when tracing is enabled or disabled. The approach currently switches all vm_call_ivar and vm_call_attrset call caches to vm_call_general any time tracing is enabled or disabled. So it could theoretically result in a slowdown for code that constantly enables or disables tracing. This approach does not handle targeted tracepoints, but from my testing, c_call and c_return events are not supported for targeted tracepoints, so that shouldn't matter. This includes a benchmark showing the performance decrease is minimal if detectable at all.

2021-01-19Replace "iff" with "if and only if"Gannon McGibbon
iff means if and only if, but readers without that knowledge might assume this to be a spelling mistake. To me, this seems like exclusionary language that is unnecessary. Simply using "if and only if" instead should suffice. Notes: Merged: https://github.com/ruby/ruby/pull/4035
2020-12-22separate rb_ractor_pub from rb_ractor_tKoichi Sasada
separate some fields from rb_ractor_t to rb_ractor_pub and put it at the beggining of rb_ractor_t and declare it in vm_core.h so vm_core.h can access rb_ractor_pub fields.

2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues. Notes: Merged: https://github.com/ruby/ruby/pull/3365

2020-03-29Clear all trace events during teardownAlan Wu
Since 0c2d81dada, not all trace events are cleared during VM teardown. This causes a crash when there is a tracepoint for `RUBY_INTERNAL_EVENT_GC_EXIT` active during teardown.

2019-12-26decouple internal.h headers卜部昌平
Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies). Notes: Merged: https://github.com/ruby/ruby/pull/2711

2019-07-24should not free local hook_list here.Koichi Sasada
exec_hooks_postcheck() clean executed hook_list if it is needed. list_exec is freed if there are no events and this list is local event (connected to specific iseq). However, iseq keeps to point this local hook_list, freed list. To prevent this situation, do not free hook_list here even if it has no events.
