Add PythonFinalizationError exception. This exception derived from RuntimeError is raised when an operation is blocked during the Python finalization. The following functions now raise PythonFinalizationError, instead of RuntimeError: * _thread.start_new_thread() * subprocess.Popen * os.fork() * os.fork1() * os.forkpty() Morever, _winapi.Overlapped finalizer now logs an unraisable PythonFinalizationError, instead of an unraisable RuntimeError.

- A junction point has two components: a print name and a substitute
|
|
name. They both describe the link target, but the substitute name is
|
|
the physical target and the print name is shown in directory listings.
|
|
- The print name must be a native name, prefixed with "\??\".
|
|
- Both names are stored after each other in the same buffer (the
|
|
PathBuffer) and both must be NUL-terminated.
|
|
- There are four members defining their respective offset and length
|
|
inside PathBuffer: SubstituteNameOffset, SubstituteNameLength,
|
|
PrintNameOffset and PrintNameLength.
|
|
- The total size we need to allocate for the REPARSE_DATA_BUFFER, thus,
|
|
is the sum of:
|
|
- the fixed header size (REPARSE_DATA_BUFFER_HEADER_SIZE)
|
|
- the size of the MountPointReparseBuffer member without the PathBuffer
|
|
- the size of the prefix ("\??\") in bytes
|
|
- the size of the print name in bytes
|
|
- the size of the substitute name in bytes
|
|
- the size of two NUL terminators in bytes */

Supports a larger number of handles than WaitForMultipleObjects
|

Note that the handles may be waited on other threads, which could cause

issues for objects like mutexes that become associated with the thread

the wait fails.
|

It is recommended to use WaitForMultipleObjects whenever possible, and

only switch to BatchedWaitForMultipleObjects for scenarios where you
|
|
control all the handles involved, such as your own thread pool or
|
|
files, and all wait objects are left unmodified by a wait (for example,
|
|
manual reset events, threads, and files/pipes).
|
|
|
|
Overlapped handles returned from this module use manual reset events.
