A patch from katsu (Katsuhiro Ueno) [Bug #19110] Notes: Merged: https://github.com/ruby/ruby/pull/6689

2022-09-11MJIT: Do not hang after forking with threadsTakashi Kokubun
First, rb_mjit_fork should call rb_thread_atfork to stop threads after fork in the child process. Unfortunately, we cannot use rb_fork_ruby to prevent this kind of mistakes because MJIT needs special handling of waiting_pid and mjit_pause/resume. Second, mjit_waitpid_finished should be checked regardless of trap_interrupt. It doesn't seem like the flag is not set when SIGCHLD is handled for an MJIT child process.
2022-09-07Exit status macros need sys/wait.h on FreeBSDNobuyoshi Nakada
2022-09-06Do not fork the process on --mjit-waitTakashi Kokubun
fork is for parallel compilation, but --mjit-wait cancels it. It's more useful to not fork it for binding.irb, debugging, etc.
2022-08-06Allow `RUBY_DEBUG_LOG` format to be emptyNobuyoshi Nakada
GCC warns of empty format strings, perhaps because they have no effects in printf() and there are better ways than sprintf(). However, ruby_debug_log() adds informations other than the format, this warning is not the case.
2022-08-02Implement Queue#pop(timeout: sec)Jean Boussier
[Feature #18774] As well as `SizedQueue#pop(timeout: sec)` If both `non_block=true` and `timeout:` are supplied, ArgumentError is raised. Notes: Merged: https://github.com/ruby/ruby/pull/6185
2022-07-26Rename rb_ary_tmp_new to rb_ary_hidden_newPeter Zhu
rb_ary_tmp_new suggests that the array is temporary in some way, but that's not true, it just creates an array that's hidden and not on the transient heap. This commit renames it to rb_ary_hidden_new. Notes: Merged: https://github.com/ruby/ruby/pull/6180

2022-07-13GVL Instrumentation: remove the EXITED count assertionJean Boussier
It's very flaky for some unknown reason. Something we have an extra EXITED event. I suspect some other test is causing this. Notes: Merged: https://github.com/ruby/ruby/pull/6133
2022-07-12Use VM Lock when mutating waiting threads listAaron Patterson
`rb_thread_wait_for_single_fd` needs to mutate the `waiting_fds` list that is stored on the VM. We need to delete the FD from the list before returning, and deleting from the list requires a VM lock (because the list is a global). [Bug #18816] [ruby-core:108771] Co-Authored-By: Alan Wu <alanwu@ruby-lang.org> Notes: Merged: https://github.com/ruby/ruby/pull/6116
2022-07-07Thread#value: handle threads killed by a forkJean Boussier
[Bug #18902] When a thread is killed because we forked, the `value` if left to `Qundef`. Returning it woudl crash the VM. Notes: Merged: https://github.com/ruby/ruby/pull/6103
2022-06-17GVL Instrumentation API: add STARTED and EXITED eventsJean Boussier
[Feature #18339] After experimenting with the initial version of the API I figured there is a need for an exit event to cleanup instrumentation data. e.g. if you record data in a {thread_id -> data} table, you need to free associated data when a thread goes away. Notes: Merged: https://github.com/ruby/ruby/pull/6029
2022-06-15Restore rb_exec_recursive_outerJohn Hawthorn
This was a public method, so we should probably keep it. Notes: Merged: https://github.com/ruby/ruby/pull/6027

[Misc #18830] Notes: Merged-By: k0kubun <takashikkbn@gmail.com>
2022-06-10Make method id explicit in rb_exec_recursive_outerJohn Hawthorn
Previously, because opt_aref and opt_aset don't push a frame, when they would call rb_hash to determine the hash value of the key, the initial level of recursion would incorrectly use the method id at the top of the stack instead of "hash". This commit replaces rb_exec_recursive_outer with rb_exec_recursive_outer_mid, which takes an explicit method id, so that we can make the hash calculation behave consistently. rb_exec_recursive_outer was documented as being internal, so I believe this should be okay to change. Notes: Merged: https://github.com/ruby/ruby/pull/6004

2022-05-24use `RUBY_DEBUG_LOG` instead of `thread_debug`Koichi Sasada
`thread_debug()` was introduced to print debug messages on `THREAD_DEBUG > 0` but `RUBY_DEBUG_LOG()` is more controllable. Notes: Merged: https://github.com/ruby/ruby/pull/5933
2022-05-24remove `NON_SCALAR_THREAD_ID` supportKoichi Sasada
`NON_SCALAR_THREAD_ID` shows `pthread_t` is non-scalar (non-pointer) and only s390x is known platform. However, the supporting code is very complex and it is only used for deubg print information. So this patch removes the support of `NON_SCALAR_THREAD_ID` and make the code simple. Notes: Merged: https://github.com/ruby/ruby/pull/5933
2022-05-17Delete autoload data from global features after autoload has completed. (#5910)Samuel Williams
* Update naming of critical section assertions macros. * Improved locking for autoload. Notes: Merged-By: ioquatix <samuel@codeotaku.com>
2022-05-15Fix various autoload race conditions. (#5898)Samuel Williams
* Add RUBY_VM_CRITICAL_SECTION for detecting unexpected context switch. * Prevent race between GC mark and autoload setup. * Protect race on autoload state. * Avoid potential race condition when allocating `autoload_featuremap`. * Add NEWS entry for autoload fixes. Notes: Merged-By: ioquatix <samuel@codeotaku.com>
2022-04-23introduce struct `rb_native_thread`Koichi Sasada
`rb_thread_t` contained `native_thread_data_t` to represent thread implementation dependent data. This patch separates them and rename it `rb_native_thread` and point it from `rb_thraed_t`. Now, 1 Ruby thread (`rb_thread_t`) has 1 native thread (`rb_native_thread`). Notes: Merged: https://github.com/ruby/ruby/pull/5836
2022-04-22rename thread internal namingKoichi Sasada
Now GVL is not process *Global* so this patch try to use another words. * `rb_global_vm_lock_t` -> `struct rb_thread_sched` * `gvl->owner` -> `sched->running` * `gvl->waitq` -> `sched->readyq` * `rb_gvl_init` -> `rb_thread_sched_init` * `gvl_destroy` -> `rb_thread_sched_destroy` * `gvl_acquire` -> `thread_sched_to_running` # waiting -> ready -> running * `gvl_release` -> `thread_sched_to_waiting` # running -> waiting * `gvl_yield` -> `thread_sched_yield` * `GVL_UNLOCK_BEGIN` -> `THREAD_BLOCKING_BEGIN` * `GVL_UNLOCK_END` -> `THREAD_BLOCKING_END` * removed * `rb_ractor_gvl` * `rb_vm_gvl_destroy` (not used) There are GVL functions such as `rb_thread_call_without_gvl()` yet but I don't have good name to replace them. Maybe GVL stands for "Greate Valuable Lock" or something like that. Notes: Merged: https://github.com/ruby/ruby/pull/5814

Use ISEQ_BODY macro to get the rb_iseq_constant_body of the ISeq. Using this macro will make it easier for us to change the allocation strategy of rb_iseq_constant_body when using Variable Width Allocation. Notes: Merged: https://github.com/ruby/ruby/pull/5698

Currently the calculation only counts the size of the struct. This commit adds the size of the associated st tables, id tables, and linked lists. Still missing is the size of the ractors and (potentially) the size of the object space. Notes: Merged: https://github.com/ruby/ruby/pull/5428

2021-08-03Fix potential hang when joining threads.Samuel Williams
If the thread termination invokes user code after `th->status` becomes `THREAD_KILLED`, and the user unblock function causes that `th->status` to become something else (e.g. `THREAD_RUNNING`), threads waiting in `thread_join_sleep` will hang forever. We move the unblock function call to before the thread status is updated, and allow threads to join as soon as `th->value` becomes defined.
