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.
* On some platforms (e.g., macOS), the user's default group access
list may exceed `NGROUPS_MAX`.
* Use upcase "GID" instead of "gid" for other than variable names.
* process.c: Add Process._fork
This API is supposed for application monitoring libraries to hook fork
event.
[Feature #17795]
Co-authored-by: Nobuyoshi Nakada <nobu@ruby-lang.org>
Instead of looking for Object::ENV (which can be overwritten),
directly look for the envtbl variable. As that is static in hash.c,
and the lookup code is in process.c, add a couple non-static
functions that will return envtbl (or envtbl#to_hash).
Fixes [Bug #18164]
All occurrences of rb_fork_ruby are followed by a call rb_thread_fork in
the created child process.
This is refactoring and a potential preparation for [Feature #17795].
(rb_fork_ruby may be wrapped by Process._fork_.)
* Rename `rb_scheduler` to `rb_fiber_scheduler`.
* Use public interface if available.
* Use `rb_check_funcall` where possible.
* Don't use `unblock` unless the fiber was non-blocking.
* 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.
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]
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().
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]
To make some kind of Ractor related extensions, some functions
should be exposed.
* include/ruby/thread_native.h
* rb_native_mutex_*
* rb_native_cond_*
* include/ruby/ractor.h
* RB_OBJ_SHAREABLE_P(obj)
* rb_ractor_shareable_p(obj)
* rb_ractor_std*()
* rb_cRactor
and rm ractor_pub.h
and rename srcdir/ractor.h to srcdir/ractor_core.h
(to avoid conflict with include/ruby/ractor.h)
