* it no longer takes ssize, which served no purpose apart from
scolding you if you got it wrong
* changed the order of the three remaining required arguments
to (format, channels, rate) to match the order in which they
must be set
* replaced the optional argument 'emulate' with 'strict': if strict
true, and the audio device does not accept the requested sampling
parameters, raise OSSAudioError
* return a tuple (format, channels, rate) reflecting the sampling
parameters that were actually set
Change the canonical name of ossaudiodev.error to
ossaudiodev.OSSAudioError (keep an alias for backwards compatibility).
Remove 'audio_types' list and 'n_audio_types' (no longer needed now that
setparameters() no longer has an 'ssize' argument to police).
* sync(), because it waits for hardware buffers to flush, which
can take several seconds depending on cirumstances (according
to the OSS docs)
* close(), because it does an implicit sync()
tp_free is NULL or PyObject_Del at the end. Because it's a base type
it must call tp_free in its dealloc function, and because it's gc'able
it must not call PyObject_Del.
inherit_slots(): Don't inherit tp_free unless the type and its base
agree about whether they're gc'able. If the type is gc'able and the
base is not, and the base uses the default PyObject_Del for its
tp_free, give the type PyObject_GC_Del for its tp_free (the appropriate
default for a gc'able type).
cPickle.c: The Pickler and Unpickler types claim to be base classes
and gc'able, but their dealloc functions didn't call tp_free.
Repaired that. Also call PyType_Ready() on these typeobjects, so
that the correct (PyObject_GC_Del) default memory-freeing function
gets plugged into these types' tp_free slots.
one good use: a subclass adding a method to express the duration as
a number of hours (or minutes, or whatever else you want to add). The
native breakdown into days+seconds+us is often clumsy. Incidentally
moved a large chunk of object-initialization code closer to the top of
the file, to avoid worse forward-reference trickery.
the itertoolsmodule.
* Taught itertools.repeat(obj, n) to treat negative repeat counts as
zero. This behavior matches that for sequences and prevents
infinite loops.
that was used to start the thread. This is useful to track down the
source of the problem when there is no traceback, as can happen when a
daemon thread gets to run after Python is finialized (a new kind of
event, somehow this is now possible due to changes in Py_Finalize()).
to use LASTMARK_SAVE()/LASTMARK_RESTORE(), based on the discussion
in patch #712900.
- Cleaned up LASTMARK_SAVE()/LASTMARK_RESTORE() usage, based on the
established rules.
- Moved the upper part of the just commited patch (relative to bug #725106)
to outside the for() loop of BRANCH OP. There's no need to mark_save()
in every loop iteration.
This problem is related to a wrong behavior from mark_save/restore(),
which don't restore the mark_stack_base before restoring the marks.
Greg's suggestion was to change the asserts, which happen to be
the only recursive ops that can continue the loop, but the problem would
happen to any operation with the same behavior. So, rather than
hardcoding this into asserts, I have changed mark_save/restore() to
always restore the stackbase before restoring the marks.
Both solutions should fix these two cases, presented by Greg:
>>> re.match('(a)(?:(?=(b)*)c)*', 'abb').groups()
('b', None)
>>> re.match('(a)((?!(b)*))*', 'abb').groups()
('b', None, None)
The rest of the bug and patch in #725149 must be discussed further.
within repeats of alternatives. The only change to the original
patch was to convert the tests to the new test_re.py file.
This patch fixes cases like:
>>> re.match('((a)|b)*', 'abc').groups()
('b', '')
Which is wrong (it's impossible to match the empty string),
and incompatible with other regex systems, like the following
examples show:
% perl -e '"abc" =~ /^((a)|b)*/; print "$1 $2\n";'
b a
% echo "abc" | sed -r -e "s/^((a)|b)*/\1 \2|/"
b a|c
- The socket module now provides the functions inet_pton and inet_ntop
for converting between string and packed representation of IP addresses.
See SF patch #658327.
This still needs a bit of work in the doc area, because it is not
available on all platforms (especially not on Windows).
