| | | | | To propagate errno in the fiber thread scheduler hook. Returns nil when no terminated process.

* Tweaked `Process::Status.wait`Nobuyoshi Nakada2020-12-091-17/+25
| | | | | | | | * revert `rb_last_status_set` * renamed the new function as `rb_process_status_new` * `rb_process_status_new` always freezes the return value * marked `Process::Status.wait` as EXPERIMENTAL, as it has not been discussed totally yet.
* Add support for non-blocking `Process.wait`.Samuel Williams2020-12-091-38/+174

* Revert getaddrinfo_a()Masaki Matsushita2020-12-071-10/+0
| | | | | | | | getaddrinfo_a() gets stuck after fork(). To avoid this, we need 1 second sleep to wait for internal worker threads of getaddrinfo_a() to be finished, but that is unacceptable. [Bug #17220] [Feature #17134] [Feature #17187]
* Call cleanup function for getaddrinfo_a(3) only before fork()Masaki Matsushita2020-12-061-9/+14
| | | | | | Previously, rb_getaddrinfo_a_before_exec() is called from before_exec(). However, the function needs to be called only before fork(). The change moves it to before_fork().
* Add a hook before fork() for getaddrinfo_a()Masaki Matsushita2020-12-041-0/+10
| | | | | | | | | We need stop worker threads in getaddrinfo_a() before fork(). This change adds a hook before fork() that cancel all outstanding requests and wait for all ongoing requests. Then, it waits for all worker threads to be finished. Fixes [Bug #17220]

* Some global variables can be accessed from ractorsKoichi Sasada2020-10-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some global variables should be used from non-main Ractors. [Bug #17268] ```ruby # ractor-local (derived from created ractor): debug '$DEBUG' => $DEBUG, '$-d' => $-d, # ractor-local (derived from created ractor): verbose '$VERBOSE' => $VERBOSE, '$-w' => $-w, '$-W' => $-W, '$-v' => $-v, # process-local (readonly): other commandline parameters '$-p' => $-p, '$-l' => $-l, '$-a' => $-a, # process-local (readonly): getpid '$$' => $$, # thread local: process result '$?' => $?, # scope local: match '$~' => $~.inspect, '$&' => $&, '$`' => $`, '$\'' => $', '$+' => $+, '$1' => $1, # scope local: last line '$_' => $_, # scope local: last backtrace '$@' => $@, '$!' => $!, # ractor local: stdin, out, err '$stdin' => $stdin.inspect, '$stdout' => $stdout.inspect, '$stderr' => $stderr.inspect, ```

* Introduce Ractor mechanism for parallel executionKoichi Sasada2020-09-031-1/+2
| | | | | | | | | | | | | | | | This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues.

* Rename `rb_current_thread_scheduler` to `rb_thread_scheduler_if_nonblocking`.Samuel Williams2020-07-201-1/+1
| | | | | Correctly capture thread before releasing GVL and pass as argument to `rb_thread_scheduler_if_nonblocking`.
* add UNREACHABLE_RETURN卜部昌平2020-06-291-0/+1
| | | | | | Not every compilers understand that rb_raise does not return. When a function does not end with a return statement, such compilers can issue warnings. We would better tell them about reachabilities.
* check_exec_redirect: do not goto into a branch卜部昌平2020-06-291-2/+1
| | | | | I'm not necessarily against every goto in general, but jumping into a branch is definitely a bad idea. Better refactor.

* Return seconds slept after Thread.scheduler wait_sleepnicholas a. evans2020-06-091-9/+9
| | | | | | Kernel#sleep should still return seconds slept, even when using a Thread.scheduler. The return value of Scheduler#wait_sleep can be ignored.
* Allow Dir.home to work for non-login procs when $HOME not setAlan D. Salewski2020-05-231-2/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow the 'Dir.home' method to reliably locate the user's home directory when all three of the following are true at the same time: 1. Ruby is running on a Unix-like OS 2. The $HOME environment variable is not set 3. The process is not a descendant of login(1) (or a work-alike) The prior behavior was that the lookup could only work for login-descended processes. This is accomplished by looking up the user's record in the password database by uid (getpwuid_r(3)) as a fallback to the lookup by name (getpwname_r(3)) which is still attempted first (based on the name, if any, returned by getlogin_r(3)). If getlogin_r(3), getpwnam_r(3), and/or getpwuid_r(3) is not available at compile time, will fallback on using their respective non-*_r() variants: getlogin(3), getpwnam(3), and/or getpwuid(3). The rationale for attempting to do the lookup by name prior to doing it by uid is to accommodate the possibility of multiple login names (each with its own record in the password database, so each with a potentially different home directory) being mapped to the same uid (as is explicitly allowed for by POSIX; see getlogin(3posix)). Preserves the existing behavior for login-descended processes, and adds the new capability of having Dir.home being able to find the user's home directory for non-login-descended processes.

* internal/process.h: add a no-warning simple wrapper for fork(2)Yusuke Endoh2020-05-021-13/+3
| | | | | | | | | | | | As fork(2) is deprecated, its calls must be guarded by `COMPILER_WARNING_IGNORED(-Wdeprecated-declarations)`. All usages of fork(2) in process have been alread guarded. A new call to fork(2) was added in ruby.c with f22c4ff359498ab342e4b6d6feb21af6004ee270. This caused a build failure on Solaris 11. It may hide a bug to guard big code unnecessarily, so this change introduces a simple wrapper "rb_fork" whose definition is guarded, and replaces all calls to fork(2) with the wrapper function.
