2017-05-21Improve Time#+ & Time#- performancewatson1978
* time.c (wadd): use internal addv() function to calculate internal value in Time object. On 64-bit machine, Time object might have Fixnum object internally by default and addv() can calculate Fixnum objects directly. * time.c (wsub): use internal subv() function due the same reason in above.

2017-05-20erb.rb: Drop unused scanner implementationk0kubun
Original `SimpleScanner` was used only in tests. Since `SimpleScanner` and `SimpleScanner2` work in the same way, I want to drop the one which can't be used in a normal situation. The only difference was `SimpleScanner` can be loaded without strscan dependency but I think there's no situation that strscan is unavailable because it's a standard library. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58819 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-05-20speed up IO#close with many threadsnormal
Today, it increases IO#close performance with many threads: Execution time (sec) name trunk after vm_thread_close 4.276 3.018 Speedup ratio: compare with the result of `trunk' (greater is better) name after vm_thread_close 1.417 This speedup comes because rb_notify_fd_close only scans threads inside rb_thread_io_blocking_region, not all threads in the VM. In the future, this type data structure may allow us to notify waiters of multiple FDs on a single thread (when using Fibers). * thread.c (struct waiting_fd): declare (rb_thread_io_blocking_region): use on-stack list waiter (rb_notify_fd_close): walk vm->waiting_fds instead (call_without_gvl): remove old field setting (th_init): ditto * vm_core.h (typedef struct rb_vm_struct): add waiting_fds list * (typedef struct rb_thread_struct): remove waiting_fd field (rb_vm_living_threads_init): initialize waiting_fds list I am now kicking myself for not thinking about this 3 years ago when I introduced ccan/list in [Feature #9632] to optimize this same function :< git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58812 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-05-19thread_sync.c: rewrite the rest using using ccan/listnormal
The performance improvement increases as the number of waiters increases, due to avoiding the O(n) behavior of rb_ary_delete on the waiting thread. Uncontended queues and condition variables performance is not altered significantly. Function entry cost is slightly increased for ConditionVariable, since the data pointer is separately allocated and not embedded into the RVALUE slot.
