2023-12-28Fix use of the rb_profile_frames start parameterDylan Thacker-Smith
Previously, it was decrementing the start argument until it reached zero without actually changing the control frame pointer. [Bug #14607]

2023-10-31[Feature #10602] Add new API rb_profile_thread_frames()Daisuke Aritomo
Add a new API rb_profile_thread_frames(), which is essentialy a per-thread version of rb_profile_frames(). While the original rb_profile_frames() always returns results about the current active thread obtained by GET_EC(), this new API takes a Thread to be profiled as an argument. This should come in handy when profiling I/O-bound programs such as webapps, since this new API allows us to learn about Threads performing I/O (which do not have the GVL). Profiling worker threads (such as Sidekiq workers) may be another application. Implements [Feature #10602] Co-authored-by: Mike Perham <mike@perham.net>
2023-10-18Show backtraces when failedKoichi Sasada
If `assert_equal(backtrace_locations.size, profile_frames.size)` in `TestProfileFrames#test_matches_backtrace_locations_main_thread` failed, we do not have enough information about it like that: ``` 1) Failure: TestProfileFrames#test_matches_backtrace_locations_main_thread [/home/runner/work/ruby/ruby/src/test/-ext-/debug/test_profile_frames.rb:148]: <31> expected but was <30>. ``` This patch shows both `backtrace_locations` and `profile_frames` if failed.
2023-07-24Use the caller location as default filename for eval family of methodsJean Boussier
[Feature #19755] Before (in /tmp/test.rb): ```ruby Object.class_eval("p __FILE__") # => "(eval)" ``` After: ```ruby Object.class_eval("p __FILE__") # => "(eval at /tmp/test.rb:1)" ``` This makes it much easier to track down generated code in case the author forgot to provide a filename argument.

2022-07-26Fix `rb_profile_frames` output includes dummy main thread frameIvo Anjo
The `rb_profile_frames` API did not skip the two dummy frames that each thread has at its beginning. This was unlike `backtrace_each` and `rb_ec_parcial_backtrace_object`, which do skip them. This does not seem to be a problem for non-main thread frames, because both `VM_FRAME_RUBYFRAME_P(cfp)` and `rb_vm_frame_method_entry(cfp)` are NULL for them. BUT, on the main thread `VM_FRAME_RUBYFRAME_P(cfp)` was true and thus the dummy thread was still included in the output of `rb_profile_frames`. I've now made `rb_profile_frames` skip this extra frame (like `backtrace_each` and friends), as well as add a test that asserts the size and contents of `rb_profile_frames`. Fixes [Bug #18907] (<https://bugs.ruby-lang.org/issues/18907>) Notes: Merged: https://github.com/ruby/ruby/pull/6114

2020-05-07Fix rb_profile_frame_classpath to handle module singletonsJean Boussier
Right now `SomeClass.method` is properly named, but `SomeModule.method` is displayed as `#<Module:0x000055eb5d95adc8>.method` which makes profiling annoying. Notes: Merged: https://github.com/ruby/ruby/pull/3084

2018-09-21escape all env properly.ko1
* vm_backtrace.c (rb_debug_inspector_open): escape all env using `rb_vm_stack_to_heap()` before making bindings. [Bug #15105] There is a complicated story of this issue: Without this patch, IFUNC frame does not escaped. A IFUNC frame points to CFUNC ep as previous ep. However, CFUNC ep can be escaped because of making bindings of Ruby level frames. IFUNC's ep can points to invalidated ep and `rb_iter_break()` will fail. This is why `any?` fails. * test/-ext-/debug/test_debug.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64800 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-04-26Fix use of `rb_profile_frames` start parametertenderlove
rb_profile_frames was always behaving as if the value given for the start parameter was 0. The reason for this was that it would check if (start > 0) { then continue without updating the control frame pointer or anything other than decrementing start.
