* Fix coroutine copy implementation on OpenBSDJeremy Evans2019-12-271-0/+4
| | | | | | | | | | OpenBSD is the only platform that uses this support by default, and it did not work because while OpenBSD supports alloca, it does not include alloca.h. This should be backported to Ruby 2.7. From George Koehler
* decouple internal.h headers卜部昌平2019-12-267-0/+14
| | | | | | | | | | | | | | | | | | Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
* coroutine/ucontext/Context.c: define __EXTENSIONS__ explicitlyYusuke Endoh2019-12-051-1/+6
| | | | | | instead of ruby/config.h, per samuel's request. https://github.com/ruby/ruby/commit/dbfd4b780e3914a3f27e92c2248254452bf0fd6b#diff-7fd78c3cc8a19b7e0637502983ec26ff
* coroutine/ucontext/Context.c: Include "ruby/config.h" for SolarisYusuke Endoh2019-12-041-0/+1
| | | | | getcontext, makecontext, and swapcontext seem to be available only when `__EXTENSION__` is defined on Solaris.
* Fix coroutine support on win32Lars Kanis2019-11-051-1/+1
| | | | | | | | | | | | | Ruby master branch currently fails on win32 MINGW at this spec: https://github.com/ruby/spec/blob/master/core/thread/element_set_spec.rb MINGW makes use of setjmp3() implemented in MSVCRT.DLL. This function traverses the SEH list up to a terminating pointer 0xFFFFFFFF. It therefore currently segfaults on NULL. The SEH linked list must be terminated by 0xFFFFFFFF instead of NULL. This fixes the issue mentioned here: https://github.com/ruby/ruby/pull/2279#issuecomment-509508810
* Add assertions to `coroutine_initialize_main`.Samuel Williams2019-07-191-2/+3
|
* Split assertions to check which one fails.Samuel Williams2019-07-191-1/+3
|
* Make fiber_pool more conservative on platforms with limited address space.Samuel Williams2019-07-185-0/+11
| | | | | | | We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address space is 32-bits or less. Fiber pool implementation enables more book keeping, and reduces upper limits, in order to minimise address space utilisation.
* Stack copying implementation of coroutines.Samuel Williams2019-07-182-0/+220
|
* Add coroutine context switch for i386-mingw32Lars Kanis2019-07-071-0/+47
| | | | | It's essentially a translation of Context.asm from Intel to AT&T syntax.
* Restore updated implementation of arm32 coroutine code, but prefer ucontext.Samuel Williams2019-06-262-4/+12
|
* Revert "coroutine/arm32/Context.S: save/restore the registers via stack"Yusuke Endoh2019-06-262-5/+4
| | | | | | | This reverts commit 6df1814c08df93bbc0b3e7a73649bcf82e126064. It caused a SEGV again: https://rubyci.org/logs/rubyci.s3.amazonaws.com/scw-9d6766/ruby-master/log/20190626T051707Z.fail.html.gz

* Revert 518adcca0a and dbe232e24eYusuke Endoh2019-06-251-6/+2
| | | | | | | | | | 518adcca0a: "Try using arm32 implementation for fibers." dbe232e24e: "Order of arguments might be incorrect in arm32 coroutine implementation." It seems to cause SEGV consistently on Ubuntu armv7l eabihf: https://rubyci.org/logs/rubyci.s3.amazonaws.com/scw-9d6766/ruby-master/log/20190625T081710Z.fail.html.gz https://rubyci.org/logs/rubyci.s3.amazonaws.com/scw-9d6766/ruby-master/log/20190625T111708Z.fail.html.gz

| | | | | | | | | | | * coroutine/win32/Context.asm: old ml version 9 needs CPU directive before `.model` directive. * win32/Makefile.sub: specify object directories to separate Win32 and Win64 targets. Win32 rule was overridden by Win64 rule and just ignored. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66059 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
