Fix for the UTF-8 decoder: it will now accept isolated surrogates
(previously it raised an exception which causes round-trips to
fail).
Added new tests for UTF-8 round-trip safety (we rely on UTF-8 for
marshalling Unicode objects, so we better make sure it works for
all Unicode code points, including isolated surrogates).
Bumped the PYC magic in a non-standard way -- please review. This
was needed because the old PYC format used illegal UTF-8 sequences
for isolated high surrogates which now raise an exception.
By default every module is imported in its own namespace, but this can
be changed by defining USE_DYLD_GLOBAL_NAMESPACE. In a future version this
define will be replaced by a runtime setting, but that needs a bit more
thought.
This code is largely based on code and feedback from Steven Majewski,
Marcel Prastawa, Manoj Plakal and other on pythonmac-sig.
type.__module__ problems (again?)
This simply initializes the __module__ local in a class statement from
the __name__ global. I'm not 100% sure that this is the correct fix,
although it usually does the right thing. The problem is that if the
class statement executes in a custom namespace, the __name__ global
may be taken from __builtins__, in which case it would have the value
__builtin__, or it may not exist at all (if the custom namespace also
has a custom __builtins__), in which case the class statement will
fail.
Nevertheless, unless someone finds a better solution, this is a 2.2.1
bugfix too.
eval_frame(): Under -Qnew, INPLACE_DIVIDE wasn't getting handed off to
INPLACE_TRUE_DIVIDE (like BINARY_DIVIDE was getting handed off to
BINARY_TRUE_DIVIDE).
Bugfix candidate.
(ditto for PyMem_Free() -> PyMem_FREE()) to fix and close SF bug
#495875 on systems that HAVE_SNPRINTF=0.
Check in on both release-22 branch and trunk.
Based on the patch from Danny Yoo. The fix is in exec_statement() in
ceval.c.
There are also changes to introduce use of PyCode_GetNumFree() in
several places.
