Charles-François Natali 225aa4f8ec Issue #12996: multiprocessing.connection: transmit the header in network byte

 2011-09-20 19:27:39 +02:00
Éric Araujo 0cdd4454f3 Remove indirection in threading (issue #10968). 
The public names (Thread, Condition, etc.) used to be factory functions
returning instances of hidden classes (_Thread, _Condition, etc.),
because (if Guido recalls correctly) this code pre-dates the ability to
subclass extension types.

It is now possible to inherit from Thread and other classes, without
having to import the private underscored names like multiprocessing did.

A doc update will follow: a patch is under discussion on the issue.

Victor Stinner 3bcc0170bd (Merge 3.2) Issue #12310: finalize the old process after _run_after_forkers() 
multiprocessing: Process._bootstrap() keeps a reference to the old process to
delay its finalization until after _run_after_forkers() as been executed. This
change should fix a crash on Mac OS X Tiger when a lock is released after a
fork.

Patch written by Charles-François Nataliv and Antoine Pitrou.

Marc-André Lemburg 8f36af7a4c Normalize the encoding names for Latin-1 and UTF-8 to 
'latin-1' and 'utf-8'.

These are optimized in the Python Unicode implementation
to result in more direct processing, bypassing the codec
registry.

Also see issue11303.
