2018-08-26thread_sync.c: common wakeup_{one,all} implementationnormal
This let us avoid looping in rb_szqueue_max_set, saves us some lines of code and reduces binary size slightly (numbers from 32-bit x86): text data bss dec hex filename before: 91272 392 156 91820 166ac thread.o after: 91200 392 156 91748 16664 thread.o Inspiration from this taken from the FUTEX_WAKE op of the Linux futex(2) syscall. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64542 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-25thread.c: use rb_hrtime_t scalar for high-resolution time operationsnormal
Relying on "struct timespec" was too annoying API-wise and used more stack space. "double" was a bit wacky w.r.t rounding in the past, so now we'll switch to using a 64-bit type. Unsigned 64-bit integer is able to give us over nearly 585 years of range with nanoseconds. This range is good enough for the Linux kernel internal time representation, so it ought to be good enough for us. This reduces the stack usage of functions while GVL is held (and thus subject to marking) on x86-64 Linux (with ppoll): rb_wait_for_single_fd 120 => 104 do_select 120 => 88 [ruby-core:88582] [Misc #15014] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64533 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-08-19thread_sync.c (rb_mutex_sleep): disable interrupt checking in ensurenormal
This is needed to reliably fix ConditionVariable#wait on Thread#kill [Bug #14999] because there is still a chance an interrupt could fire and prevent lock acquisition after an ensure statement. Arguably, rb_mutex_lock itself should be uninterruptible, but that already prevents bootstraptest/test_thread.rb from completing and probably breaks existing use cases. For reference, POSIX expressly forbids EINTR from pthread_mutex_lock. [ruby-core:88556] [Bug #14999] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64476 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Calling rb_mutex_sleep directly should avoid thread-switching/interrupt checking which can lead to occasional failures. Unfortunately, this means overriding Mutex#sleep is no longer supported. Will let this commit run for a bit see if CI failures from ConditionVariable specs continue... cf. https://rubyci.org/logs/rubyci.s3.amazonaws.com/ubuntu/ruby-trunk/log/20180817T213003Z.fail.html.gz [ruby-core:88524] [Bug #14999] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64436 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-16thread_sync.c (rb_mutex_lock): acquire lock before being killednormal
We (the thread acquiring the mutex) need to acquire the mutex before being killed to work with ConditionVariable#wait. Thus we reinstate the acquire-immediately-after-sleeping logic from pre-r63711 while still retaining the acquire-after-checking-for-interrupts logic from r63711.

Instead of relying on a native condition variable and mutex for every Ruby Mutex object, use a doubly linked-list to implement a waiter queue in the Mutex. The immediate benefit of this is reducing the size of every Mutex object, as some projects have many objects requiring synchronization. In the future, this technique using a linked-list and on-stack list node (struct mutex_waiter) should allow us to easily transition to M:N threading model, as we can avoid the native thread dependency to implement Mutex. We already do something similar for autoload in variable.c, and this was inspired by the Linux kernel wait queue (as ccan/list is inspired by the Linux kernel linked-list). Finaly, there are big performance improvements for Mutex benchmarks, especially in contended cases: measure target: real name |trunk |built ----------------|------:|------: loop_whileloop2 | 0.149| 0.148 vm2_mutex* | 0.893| 0.651 vm_thread_mutex1| 0.809| 0.624 vm_thread_mutex2| 2.608| 0.628 vm_thread_mutex3| 28.227| 0.881 Speedup ratio: compare with the result of `trunk' (greater is better) name |built ----------------|------: loop_whileloop2 | 1.002 vm2_mutex* | 1.372 vm_thread_mutex1| 1.297 vm_thread_mutex2| 4.149 vm_thread_mutex3| 32.044 Tested on AMD FX-8320 8-core at 3.5GHz * thread_sync.c (struct mutex_waiter): new on-stack struct (struct rb_mutex_struct): remove native lock/cond, use ccan/list (rb_mutex_num_waiting): new function for debug_deadlock_check (mutex_free): remove native_*_destroy (mutex_alloc): initialize waitq, remove native_*_initialize (rb_mutex_trylock): remove native_mutex_{lock,unlock} (lock_func): remove (lock_interrupt): remove (rb_mutex_lock): rewrite waiting path to use native_sleep + ccan/list (rb_mutex_unlock_th): rewrite to wake up from native_sleep using rb_threadptr_interrupt (rb_mutex_abandon_all): empty waitq * thread.c (debug_deadlock_check): update for new struct (rb_check_deadlock): ditto [ruby-core:80913] [Feature #13517] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58604 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
