2020-08-24Update PTY.open documentation to document it yields a single argument [ci skip]Jeremy Evans
For a regular block, accepting two arguments is fine as the array will be autosplatted. However, a lambda that accepts two arguments will not work. We could change the implementation to yield two arguments instead of an array with a single argument, but that would be less backwards compatible. I'm only changing the call-seq to be precise, other examples pass a literal block that accepts two arguments, and I left those alone as that will be the most common usage. Fixes [Bug #17094]

2019-12-26decouple internal.h headers卜部昌平
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). Notes: Merged: https://github.com/ruby/ruby/pull/2711
2019-08-27rb_ensure now free from ANYARGS卜部昌平
After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit deletes ANYARGS from rb_ensure, which also revealed many arity / type mismatches.

2018-07-05unrevert r63852 but keep SIGCHLD path disabled for win32normal
Reading win32/win32.c waitpid implementation, maybe waitpid(-1, ...) on that platform will never conflict with mjit use of waitpid. In any case, I've added WAITPID_USE_SIGCHLD macro to vm_core.h so it can be easy for Linux/BSD users to test (hopefully!) win32-compatible code. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63855 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-06-27hijack SIGCHLD handler for internal usenormal
Use a global SIGCHLD handler to guard all callers of rb_waitpid. To work safely with multi-threaded programs, we introduce a VM-wide waitpid_lock to be acquired BEFORE fork/vfork spawns the process. This is to be combined with the new ruby_waitpid_locked function used by mjit.c in a non-Ruby thread. Ruby-level SIGCHLD handlers registered with Signal.trap(:CHLD) continues to work as before and there should be no regressions in any existing use cases. Splitting the wait queues for PID > 0 and groups (PID <= 0) ensures we favor PID > 0 callers. The disabling of SIGCHLD in rb_f_system is longer necessary, as we use deferred signal handling and no longer make ANY blocking waitpid syscalls in other threads which could "beat" the waitpid call made by rb_f_system. We prevent SIGCHLD from firing in normal Ruby Threads and only enable it in the timer-thread, to prevent spurious wakeups from in test/-ext-/gvl/test_last_thread.rb with MJIT enabled. I've tried to guard as much of the code for RUBY_SIGCHLD==0 using C "if" statements rather than CPP "#if" so to reduce the likelyhood of portability problems as the compiler will see more code. We also work to suppress false-positives from Process.wait(-1, Process::WNOHANG) to quiets warnings from spec/ruby/core/process/wait2_spec.rb with MJIT enabled. Lastly, we must implement rb_grantpt for ext/pty. We need a MJIT-compatible way of supporting grantpt(3) which may spawn the `pt_chown' binary and call waitpid(2) on it.
