gh-107913: Fix possible losses of OSError error codes (GH-107930)
Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be
called immediately after using the C API which sets errno or the Windows
error code.

gh-106320: Remove private _PyLong_FileDescriptor_Converter() (#108503)
Move the private _PyLong converter functions to the internal C API

* _PyLong_FileDescriptor_Converter(): moved to pycore_fileutils.h
* _PyLong_Size_t_Converter(): moved to pycore_long.h

Argument Clinic now emits includes for pycore_fileutils.h and
pycore_long.h when these functions are used.

gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)
Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules.  We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).

bpo-46016: fcntl module add FreeBSD's F_DUP2FD_CLOEXEC flag support (GH-29993) 2021-12-08 23:28:51 +01:00

bpo-41586: Add pipesize parameter to subprocess & F_GETPIPE_SZ and F_SETPIPE_SZ to fcntl. (GH-21921)
* Add F_SETPIPE_SZ and F_GETPIPE_SZ to fcntl module
* Add pipesize parameter for subprocess.Popen class

This will allow the user to control the size of the pipes.
On linux the default is 64K. When a pipe is full it blocks for writing.
When a pipe is empty it blocks for reading. On processes that are
very fast this can lead to a lot of wasted CPU cycles. On a typical
Linux system the max pipe size is 1024K which is much better.
For high performance-oriented libraries such as xopen it is nice to
be able to set the pipe size.

The workaround without this feature is to use my_popen_process.stdout.fileno() in
conjuction with fcntl and 1031 (value of F_SETPIPE_SZ) to acquire this behavior.

  Adds a sanity check to avoid a *very rare* infinite loop due to a corrupt tls
  key list data structure in the thread startup path.

  This change is a companion to r60148 which already successfully dealt with a
  similar issue on thread shutdown.

  In particular this loop has been observed happening from this call path:
   #0  in find_key ()
   #1  in PyThread_set_key_value ()
   #2  in _PyGILState_NoteThreadState ()
   #3  in PyThreadState_New ()
   #4  in t_bootstrap ()
   #5  in pthread_start_thread ()

  I don't know how this happens but it does, *very* rarely.  On more than
  one hardware platform.  I have not been able to reproduce it manually.
  (A flaky mutex implementation on the system in question is one hypothesis).

  As with r60148, the spinning we managed to observe in the wild was due to a
  single list element pointing back upon itself.
