+ A new scheme for determining whether an address belongs to a pymalloc
arena. This should be 100% reliable. The poolp->pooladdr and
poolp->magic members are gone. A new poolp->arenaindex member takes
their place. Note that the pool header overhead doesn't actually
shrink, though, since the header is padded to a multiple of 8 bytes.
+ _PyMalloc_Free and _PyMalloc_Realloc should now be safe to call for
any legit address, whether obtained from a _PyMalloc function or from
the system malloc/realloc. It should even be safe to call
_PyMalloc_Free when *not* holding the GIL, provided that the passed-in
address was obtained from system malloc/realloc. Since this is
accomplished without any locks, you better believe the code is subtle.
I hope it's sufficiently commented.
+ The above implies we don't need the new PyMalloc_{New, NewVar, Del}
API anymore, and could switch back to PyObject_XXX without breaking
existing code mixing PyObject_XXX with PyMem_{Del, DEL, Free, FREE}.
Nothing is done here about that yet, and I'd like to see this new
code exercised more first.
+ The small object threshhold is boosted to 256 (the max). We should
play with that some more, but the old 64 was way too small for 2.3.
+ Getting a new arena is now done via new function new_arena().
+ Removed some unused macros, and squashed out some macros that were
used only once to define other macros.
+ Arenas are no longer linked together. A new vector of arena base
addresses had to be created anyway to make address classification
bulletproof.
+ A lot of the patch size is an illusion: given the way address
classification works now, it was more convenient to switch the
sense of the prime "if" tests in the realloc and free functions,
so the "if" and "else" blocks got swapped.
+ Assorted minor code, comment and whitespace cleanup.
Back to the Windows installer <wink>.
(if a single newline convention is used in the sourcefile), and the
"save options" has a newline style radio button.
The creator radio button also has the new choices PythonW and None.
Just: just shout (and revert) if you don't agree.
Added a -D flag (can really only be specified on OSX commandline) to not
revector sys.stderr, for debugging the IDE itself. Not sure whether
this should stay.
return None.
For now, if the user asks for TEXT files files without type are also
accepted. But it is time to phase out StandardGetFile and friends, really.
Walter Doerwald provided a patch, which I've modified in two ways:
1) (Uncontroversial) Removed code to make module work in earlier versions of
Python without the unicode() built-in
2) (Poss. controversial) Instead of making string.zfill take the repr()
of non-string objects, take the str().
Should a warning be added to this branch of the code so that the automatic
str() can be deprecated?
2.2.2 bugfix candidate, assuming the repr()->str() change is deemed OK.
include them using \verbatiminput. This has the advantage that pages
can still break at reasonable places, and examples that go longer than
a page won't get cut off.
Make a few small markup adjustments for consistency.
Explain that PyObject_New() is not a C function but a polymorphic
beast that returns a pointer to the type that's passed as the first
arg.
Explain why type objects use the PyObject_VAR_HEAD.
It appears that getcomments() can get called for classes defined in
C. Since these don't have source code, it can't do anything useful.
A function buried many levels deep was raising a TypeError that was
not caught.
Who knows why this broke...
