* [Feature #19590] Show the invalid clock argumentNobuyoshi Nakada2023-04-131-6/+15
| | | | | Include the failed clock argument in the error message from `Process.clock_gettime` and `Process.clock_getres`.
* [DOC] Clarify behavior of abort() with no argumentDaniel DeLorme2023-04-051-1/+2
| | | | | | Since Ruby 2.7 it prints the message and backtrace of $! Fixes [Bug #19578]
* Revert "Fix transient heap mode"Aaron Patterson2023-04-041-34/+0
| | | | | | | | This reverts commit 87253d047ce35e7836b6f97edbb4f819879a3b25. Revert "Implement `Process.warmup`" This reverts commit ba6ccd871442f55080bffd53e33678c0726787d2.
* Implement `Process.warmup`Jean Boussier2023-04-041-0/+34
| | | | | | | | | | | | [Feature #18885] For now, the optimizations performed are: - Run a major GC - Compact the heap - Promote all surviving objects to oldgen Other optimizations may follow.
* PID cache is never cleared where `fork` is not usedNobuyoshi Nakada2023-04-041-0/+2

* Cache pid itself instead of converted VALUENobuyoshi Nakada2023-03-241-18/+6
|
* thread_pthread.c: Use a `fork_gen` to protect against fork instead of getpid()Jean Boussier2023-03-231-12/+7
| | | | | | | | | | | | | | | [Feature #19443] Until recently most libc would cache `getpid()` so this was a cheap check to make. However as of glibc version 2.25 the PID cache is removed and calls to getpid() always invoke the actual system call which significantly degrades the performance of existing applications. The reason glibc removed the cache is that some libraries were bypassing fork(2) by issuing system calls themselves, causing stale cache issues. That isn't a concern for Ruby as bypassing MRI's primitive for forking would render the VM unusable, so we can safely cache the PID.
* Suppress a compiler warning on GCC in process.cPeter Zhu2023-03-221-0/+8
| | | | | | | rb_pid_t is 32 bits on some platforms, which will cause a warning on GCC due to POSFIXABLE always returning true. include/ruby/internal/arithmetic/fixnum.h:43:31: warning: comparison is always true due to limited range of data type [-Wtype-limits]

* Cache `Process.pid`Jean Boussier2023-03-201-3/+21
| | | | | | | | | | | | | | | | | | | | [Feature #19443] It's not uncommon for database client and similar network libraries to protect themselves from Process.fork by regularly checking Process.pid Until recently most libc would cache `getpid()` so this was a cheap check to make. However as of glibc version 2.25 the PID cache is removed and calls to `getpid()` always invoke the actual system call which significantly degrades the performance of existing applications. The reason glibc removed the cache is that some libraries were bypassing `fork(2)` by issuing system calls themselves, causing stale cache issues. That isn't a concern for Ruby as bypassing MRI's primitive for forking would render the VM unusable, so we can safely cache the PID.

* [DOC] Tweak the doc for `Process.kill` signatureKoichi ITO2022-09-211-1/+1
| | | | | | | | | | | | | Replacing `...` with `*pids` seems to clarify the expected variadic arguments. Note that the expected arguments are two or more with a signal and pids. That is, the method must have at least one pid, which cannot be omitted: ```console % ruby -e 'Process.kill(0)' -e:1:in `kill': wrong number of arguments (given 1, expected 2+) (ArgumentError) from -e:1:in `<main>' ```
* Ignore EPERM which means already being process-leaderNobuyoshi Nakada2022-09-201-1/+2
|
* Reduce fork calls in daemonNobuyoshi Nakada2022-09-191-10/+4
| | | | | | The forked child process is a grandchild process from the viewpoint of the process which invoked the caller process. That means the child is detached at that point, and it does not need to fork twice.
* MJIT: Do not hang after forking with threadsTakashi Kokubun2022-09-111-0/+1
| | | | | | | | | | | First, rb_mjit_fork should call rb_thread_atfork to stop threads after fork in the child process. Unfortunately, we cannot use rb_fork_ruby to prevent this kind of mistakes because MJIT needs special handling of waiting_pid and mjit_pause/resume. Second, mjit_waitpid_finished should be checked regardless of trap_interrupt. It doesn't seem like the flag is not set when SIGCHLD is handled for an MJIT child process.
* Call appropriate hooks on MJIT's forkTakashi Kokubun2022-09-041-0/+23

* Stop using casted `rb_syswait` as `proc_syswait`Nobuyoshi Nakada2022-08-071-5/+1
| | | | | | The argument of `rb_syswait` is now `rb_pid_t` which may differ from `int`. Also it is an undefined behavior to take the result of casted void function (in `rb_protect`).
* Fix the sizes comparisonNobuyoshi Nakada2022-08-061-1/+1
| | | | `proc_syswait` will be called with a `VALUE` argument.
