Neal Norwitz 4f3be8a0a9 Security patches from Apple: prevent int overflow when allocating memory 2008-07-31 17:08:14 +00:00
Neal Norwitz 83ac0144fa Backport code from r65182:
Issue #2620: Overflow checking when allocating or reallocating memory
was not always being done properly in some python types and extension
modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
all been updated to perform better checks and places in the code that
would previously leak memory on the error path when such an allocation
failed have been fixed.

Amaury Forgeot d'Arc b15bdf7f7a #Issue3088 in-progress: Race condition with instances of classes derived from threading.local:
When a thread touches such an object for the first time, a new thread-local __dict__ is created,
and the __init__ method is run.
But a thread switch can occur here; if the other thread touches the same object, it installs another
__dict__; when the first thread resumes, it updates the dictionary of the second...

This is the deep cause of the failures in test_multiprocessing involving "managers" objects.

Backport of r64601.

Gregory P. Smith 631df7550f Backport r61450 from trunk:
Fix chown on 64-bit linux.  It needed to take a long (64-bit on 64bit linux) as
 uid and gid input to accept values >=2**31 as valid while still accepting
 negative numbers to pass -1 to chown for "no change".

 Fixes issue1747858.

can't be triggered from Python code.

Gerhard Häring 14fbf29692 - Backported a workaround for a bug in SQLite 3.2.x/3.3.x versions where a
statement recompilation with no bound parameters lead to a segfault
- Backported a fix necessary because of an SQLite API change in version 3.5.
  This prevents segfaults when executing empty queries, like our test suite
  does.
