* Ensure SIGCHLD always uses a signal handler. (#7819)Samuel Williams2023-05-161-0/+3
|
* Remove explicit SIGCHLD handling. (#7816)Samuel Williams2023-05-151-76/+6
| | | | | | | | | * Remove unused SIGCHLD handling. * Remove unused `init_sigchld`. * Remove unnecessary `#define RUBY_SIGCHLD (0)`. * Remove unused `SIGCHLD_LOSSY`.
* Use the rb_sys_fail_str macro in signal.cKunshan Wang2023-05-151-0/+1
| | | | | | | | | | | Let signal.c include "internal/error.h" explicitly to ensure that the identifier rb_sys_fail_str in signal.c refers to the macro defined in "internal/error.h" instead of the actual function. That macro reads errno before evaluating its argument. Without this change, the rb_signo2signm(sig) expression in the "trap" function in signal.c will overwrite the errno before the actual rb_sys_fail_str function reads the errno.
* Remove SIGCHLD `waidpid`. (#7527)Samuel Williams2023-03-151-39/+1
| | | | | | | * Remove `waitpid_lock` and related code. * Remove un-necessary test. * Remove `rb_thread_sleep_interruptible` dead code.

* Use free instead of xfree to free altstackYusuke Endoh2021-09-061-1/+4
| | | | | | | | | The altstack memory of a thread may be free'ed even after the VM is destructed. After that, GC is no longer available, so calling xfree may lead to a segfault. This changeset uses the bare free function to free the altstack memory instead of xfree. [Bug #18126]

* Fix -Wundef warnings for patterns `#if HAVE`Benoit Daloze2021-05-041-1/+1
| | | | | | * See [Feature #17752] * Using this to detect them: git grep -P 'if\s+HAVE' | grep -Pv 'HAVE_LONG_LONG|/ChangeLog|HAVE_TYPEOF'
* Replace "iff" with "if and only if"Gannon McGibbon2021-01-191-1/+1
| | | | | | | iff means if and only if, but readers without that knowledge might assume this to be a spelling mistake. To me, this seems like exclusionary language that is unnecessary. Simply using "if and only if" instead should suffice.

* trap on non-main ractorKoichi Sasada2020-12-121-0/+6
| | | | | trap can accept blopck/Proc and it can violate Rator isolation, so the Proc should be isolatable when trap is used on non-main ractor.
* Introduce Ractor mechanism for parallel executionKoichi Sasada2020-09-031-2/+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.

* 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.

| | | | | I'm not necessarily against every goto in general, but jumping into a branch is definitely a bad idea. Better refactor.

* thread_pthread.c: allocate sigaltstack before pthread_createYusuke Endoh2020-03-061-4/+15
| | | | | | | | | | | | A new (not-initialized-yet) pthread attempts to allocate sigaltstack by using xmalloc. It may cause GC, but because the thread is not initialized yet, ruby_native_thread_p() returns false, which leads to "[FATAL] failed to allocate memory" and exit. In fact, we can observe the error message in the log of OpenBSD CI: https://rubyci.org/logs/rubyci.s3.amazonaws.com/openbsd-current/ruby-master/log/20200306T083005Z.log.html.gz This changeset allocates sigaltstack before pthread is created.
* decouple internal.h headers卜部昌平2019-12-261-23/+21
| | | | | | | | | | | | | | | | | | 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).
* Deprecate rb_eval_cmd, add rb_eval_cmd_kwJeremy Evans2019-11-181-1/+1
| | | | | | | | rb_eval_cmd takes a safe level, and now that $SAFE is deprecated, it should be deprecated as well. Replace with rb_eval_cmd_kw, which takes a keyword flag. Switch the two callers to this function.
* Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans2019-11-181-5/+1
| | | | | | This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby.
* Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans2019-11-181-6/+4
| | | | | | | | | | | | | | | | | This removes the security features added by $SAFE = 1, and warns for access or modification of $SAFE from Ruby-level, as well as warning when calling all public C functions related to $SAFE. This modifies some internal functions that took a safe level argument to no longer take the argument. rb_require_safe now warns, rb_require_string has been added as a version that takes a VALUE and does not warn. One public C function that still takes a safe level argument and that this doesn't warn for is rb_eval_cmd. We may want to consider adding an alternative method that does not take a safe level argument, and warn for rb_eval_cmd.

* signal.c: save the original sighandlers for fatal signalsYusuke Endoh2019-10-091-11/+21
| | | | | | | | | | | On Android, a signal handler that is not SIG_DFL is set by default for SIGSEGV. Ruby's install_sighandler inserts Ruby's handler only when the signal has no handler, so it does not insert Ruby's SEGV report handler, which caused some test failures. This changeset forces to install Ruby's handler for some fatal signals (sigbus, sigsegv, and sigill). They keep the original handlers, and call them when the interpreter receives the signals.
* error.c (rb_bug_for_fatal_signal): renamed from rb_bug_contextYusuke Endoh2019-10-091-3/+3
| | | | | | | | | | Just refactoring. The name "rb_bug_context" is completely unclear for me. (Can you see that "context" means "machine register context"?) The context is available only when a fatal signal (sigbus, sigsegv, or sigill) is received; in fact, the function is used only for fatal signals. So, I think the name should be changed.
* signal.c (ruby_abort): move the definition for refactoringYusuke Endoh2019-10-091-18/+17
| | | | | | The three functions for fatal signals, sigbus, sigsegv, and sigill, are a family. The definition of ruby_abort had interrupted them for no reason. This change just moves the definition after the family.
* signal.c: Use MINSIGSTKSZ by casting to intYusuke Endoh2019-10-051-2/+5
| | | | | | | | | | | | | MINSIGSTKSZ is unsigned int in OpenBSD, which makes a warning of comparison: ``` signal.c:535:14: warning: comparison of integers of different signs: 'int' and 'unsigned int' [-Wsign-compare] if (size < MINSIGSTKSZ) ~~~~ ^ ~~~~~~~~~~~ 1 warning generated. ``` https://rubyci.org/logs/rubyci.s3.amazonaws.com/openbsd-current/ruby-master/log/20191004T200009Z.log.html.gz
* move docs around [ci skip]卜部昌平2019-08-291-36/+0
| | | | To properly generate documents.
* drop-in type check for rb_define_module_function卜部昌平2019-08-291-2/+2
| | | | | | We can check the function pointer passed to rb_define_module_function like how we do so in rb_define_method. The difference is that this changeset reveales lots of atiry mismatches.
* signal.c: Don't mark ruby_abort as NORETURN on SolarisYusuke Endoh2019-08-271-0/+2
| | | | | | | | | | | to suppress a warning. ``` signal.c: In function 'ruby_abort': signal.c:987:1: warning: 'noreturn' function does return } ^ ```
* Renamed ruby_finalize_{0,1}Nobuyoshi Nakada2019-08-131-2/+1

* signal.c: make signame_prefix a nul-terminated stringYusuke Endoh2019-08-011-3/+3
| | | | | | | | | | | | | | | | gcc 9.1.0 warns this. ``` signal.c:258:46: warning: '%.*s' directive argument is not a nul-terminated string [-Wformat-overflow=] 258 | rb_raise(rb_eArgError, "unsupported signal `%.*s%"PRIsVALUE"'", | ^~~~ 259 | prefix, signame_prefix, vsig); | ~~~~~~~~~~~~~~ signal.c:200:19: note: referenced argument declared here 200 | static const char signame_prefix[3] = "SIG"; | ^~~~~~~~~~~~~~ ``` https://rubyci.org/logs/rubyci.s3.amazonaws.com/ubuntu/ruby-master/log/20190801T033009Z.log.html.gz
