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. This reverts commit 6505c77501f1924571b2fe620c5c7b31ede0cd22. Notes: Merged: https://github.com/ruby/ruby/pull/4689

2021-06-14Wake up join list within thread EC context. (#4471)Samuel Williams
* Wake up join list within thread EC context. * Consume items from join list so that they are not re-executed. If `rb_fiber_scheduler_unblock` raises an exception, it can result in a segfault if `rb_threadptr_join_list_wakeup` is not within a valid EC. This change moves `rb_threadptr_join_list_wakeup` into the thread's top level EC which initially caused an infinite loop because on exception will retry. We explicitly remove items from the thread's join list to avoid this situation. * Verify the required scheduler interface. * Test several scheduler hooks methods with broken `unblock` implementation.

2021-04-08Document how to handle kill/terminate interrupts in Thread.handle_interruptJeremy Evans
The kill/terminate interrupts are internally handled not as Exception instances, but as integers. So using Exception doesn't handle these interrupts, but Object does. You can use Integer if you only want to handle kill/terminate interrupts, but that's probably more of an implementation detail, while handling Object should work regardless of the implementation.

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
