* Convert select module to PEP-384
Summary: Do the necessary versions to be Pyro-compatible, including migrating `PyType_Ready` to `PyType_FromSpec` and moving static data into a new `_selectstate` struct.
* 📜🤖 Added by blurb_it.
* Fixup Mac OS/X build
In _localemodule.c and selectmodule.c, remove dead code that would
cause double decrefs if run.
In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases
where a new list is populated and there is no possibility of an error.
In addition, check if the list changed size in the loop in array_array_fromlist().
select() calls are retried on EINTR (per PEP 475). However, if a
timeout was provided and the deadline has passed after running the
signal handlers, rlist, wlist and xlist should be cleared since select(2)
left them unmodified.
Although the kernel accepts any negative value for timeout, the
documented value to block indefinitely is -1.
This commit also makes the code similar to select.poll.poll().
* `flags` is indeed deprecated, but there is a validation on its value for
backwards compatibility reasons. This adds mention of this in the docs.
* The docs say that `sizehint` is deprecated and ignored, but it is still
used when `epoll_create1()` is unavailable. This adds mention of this in
the docs.
* `sizehint=-1` is acceptable again, and is replaced with `FD_SETSIZE-1`.
This is needed to have a default value available at the Python level,
since `FD_SETSIZE` is not exposed to Python. (see: bpo-31938)
* Reject `sizehint=0` since it is invalid to pass on to `epoll_create()`.
The relevant tests have also been updated.
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments. This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.
Always pass -1, or INFTIM where defined, to the poll() system call when
a negative timeout is passed to the poll.poll([timeout]) method in the
select module. Various OSes throw an error with arbitrary negative
values.
timeout when interrupted by a signal, except if the signal handler raises an
exception. This change is part of the PEP 475.
The asyncore and selectors module doesn't catch the InterruptedError exception
anymore when calling select.select(), since this function should not raise
InterruptedError anymore.
* _Py_open() now raises exceptions on error. If open() fails, it raises an
OSError with the filename.
* _Py_open() now releases the GIL while calling open()
* Add _Py_open_noraise() when _Py_open() cannot be used because the GIL is not
held
