Jean Boussier ba6ccd8714 Implement `Process.warmup`
[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 used 2023-04-04 11:29:57 +09:00
Nobuyoshi Nakada 3e7d1cbceb Cache pid itself instead of converted VALUE 2023-03-24 14:22:02 +09:00
Jean Boussier 3563e1383f thread_pthread.c: Use a `fork_gen` to protect against fork instead of getpid()
[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.

Peter Zhu 3210130993 Suppress a compiler warning on GCC in process.c
rb_pid_t is 32 bits on some platforms, which will cause a warning on GCC
due to POSFIXABLE always returning true.

Jean Boussier 1db8951d3a Cache `Process.pid`
[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.

Koichi ITO e3b178066b [DOC] Tweak the doc for `Process.kill` signature
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>'

Nobuyoshi Nakada ae07336529 Reduce fork calls in daemon
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 threads
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.

Stop using casted `rb_syswait` as `proc_syswait`
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`).

Kevin Newton fc6fd4c31e Accurately report VM memsize
Currently the calculation only counts the size of the struct. This commit adds the size of the associated st tables, id tables, and linked lists.

Still missing is the size of the ractors and (potentially) the size of the object space.
