2024-04-24Add ruby_mimcallocPeter Zhu
Many places call ruby_mimmalloc then MEMZERO. This can be reduced by using ruby_mimcalloc instead.

non-blocking by default. (#10481)
2024-04-07Revert "Enumerator should use a non-blocking fiber. (#10478)" (#10480)Samuel Williams
This reverts commit dfa0897de89251a631a67460b941cd24a14c9b55. This commit accidentally included some change in `parse.h`. Reverting and re-applying the relevant changes.
2024-04-07Enumerator should use a non-blocking fiber. (#10478)Samuel Williams
2024-03-25Mark fiber stacks in rb_execution_context_markKJ Tsanaktsidis
Currently, fiber stacks are marked separately from the rest of the execution context. The fiber code deliberately does _NOT_ set ec->machine.stack_end on the saved EC, so that the code in `rb_execution_context_mark` does not mark it; instead, the stack marking is done in `cont_mark`. Instead, we can set ec->machine.stack_end, and skip out on doing the stack marking separately in `cont_mark`; that way, all machine stack marking shares the same code (which does the nescessary ASAN things). [Bug #20310]

2024-03-04Disable callcc when ASAN is enabledKJ Tsanaktsidis
callcc's implementation is fundamentally incompatible with ASAN. Since callcc is deprecated and almost never used, it's probably OK to disable callcc when ruby is compiled with ASAN. [Bug #20273]

2023-12-22FREE_AT_EXIT: Don't free main stack post-forkJohn Hawthorn
When a forked process was started in a thread, this would result in a double-free during the child process exit. RUBY_FREE_AT_EXIT=1 ./miniruby -e 'Thread.new { fork { } }.join; Process.waitpid' This is because the main thread in the forked process was not the initial VM thread, and the new thread's stack was freed as part of objectspace iteration. This change also allows rb_threadptr_root_fiber_release to run without EC being available.

2023-10-19Avoid initializing jit_cont_lock multiple timesTakashi Kokubun
Contrary to my initial assumption, rb_threadptr_root_fiber_setup() is called for each Ractor, not just once at boot. I changed the place to call rb_jit_cont_init() to avoid calling it multiple times.

2022-10-19MJIT: Stop using the VM barrier for jit_contTakashi Kokubun
This solves multiple problems. First, RB_VM_LOCK_ENTER/LEAVE is a barrier. We could at least use the _NO_BARRIER variant. Second, this doesn't need to interfere with GC or other GVL users when multiple Ractors are used. This needs to be used in very few places, so the benefit of fine-grained locking would outweigh its small maintenance cost. Third, it fixes a crash for YJIT. Because YJIT is never disabled until a process exits unlike MJIT that finishes earlier, we could call jit_cont_free when EC no longer exists, which crashes RB_VM_LOCK_ENTER.

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
