2014-05-18signal.c: use mcontext_tnobu
* signal.c (check_stack_overflow): use mcontext_t. the struct tag name is not portable. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45997 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-05-18signal.c: check stack overflow by SPnobu
* signal.c (check_stack_overflow): raise SystemStackError if SP register and fault address is in the same page or the next, on x86 Mac OS X. [EXPERIMENTAL] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45995 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-05-12signal.c: check the next page toonobu
* signal.c (check_stack_overflow): check the next page too. SP in ucontext is not decremented yet when `push` failed, so the fault page can be the next. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45924 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-11-21* eval_intern.h (SAVE_ROOT_JMPBUF): workaround for the failure ofusa
test/ruby/test_exception.rb on Windows. wrap by __try and __exception statements on mswin to raise SIGSEGV when EXCEPTION_STACK_OVERFLOW is occurred, because MSVCRT doesn't handle the exception. however, (1) mingw-gcc doesn't support __try and __exception statements, and (2) we cannot retry SystemStackError after this change yet (maybe crashed) because SEH and longjmp() are too uncongenial. * signal.c (check_stack_overflow, CHECK_STACK_OVERFLOW): now defined on Windows, too. * thread_win32.c (ruby_stack_overflowed_p): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43748 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-05-14* signal.c: need to include unistd.h for write(2).usa
unistd.h is now included via ruby/defines.h, but should implicitly include here. (suggested by kosaki) git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40743 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2012-12-23* thread.c: rename methods:ko1
from Thread.async_interrupt_timing to Thread.handle_interrupt, from Thread.async_interrupted? to Thread.pending_interrupt?. Also rename option from `defer' to `never'. [ruby-core:51074] [ruby-trunk - Feature #6762] * vm_core.c, thread.c: rename functions and data structure `async_errinfo' to `pending_interrupt'. * thread.c: add global variables sym_immediate, sym_on_blocking and sym_never. * cont.c, process.c, vm.c, signal.c: ditto. * lib/sync.rb, lib/thread.rb: catch up this renaming. * test/ruby/test_thread.rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38577 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

explicitly. Fix compile error on Mac OS X. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38415 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-12-15* signal.c (default_handler): remove rb_register_sigaltstack()kosaki
call. sigaltstack was already registered when creating threads. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38410 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-12-15* signal.c (rb_sigaltstack_size): new. calculate stack size forkosaki
sigsegv handler. enlarge value when x86 or x86_64 on Linux. Linux has very small MINSIGSTKSZ size (2048 bytes) and our sigsegv routine need 5KiB at least. [Bug #7141] * internal.h: add declaration of rb_sigaltstack_size(). * vm_core.h: remove ALT_STACK_SIZE definition. * signal.c (rb_register_sigaltstack): replace ALT_STACK_SIZE with rb_sigaltstack_size(); * gc.c (Init_heap): ditto. * vm.c (th_init): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38409 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-12-14* signal.c (rb_f_kill): remove rb_thread_polling() because thiskosaki
has no good effect and makes meaningless 100ms delay. 1) when sending signal to another process, waiting has just silly. 2) when sending signal to current process, 100ms is often not enough time to wait. It depend on kernel behavior. And, rb_thread_polling() doesn't make sense anyway. When rb_thread_alone() is true, it doesn't wait at all and Process.kill() users don't expect threading changes Process.kill() behavior.
