I don't think the fix here is very good, but I'm not sure what would
be better. In particular, we should not be defining _SGIAPI, but lots
of things break if we remove it.
* Extended DB & DBEnv set_get_returns_none functionality to take a
"level" instead of a boolean flag. The boolean 0 and 1 values still
have the same effect. A value of 2 extends the "return None instead
of raising an exception" behaviour to the DBCursor set methods.
This will become the default behaviour in pybsddb 4.2.
* Fixed a typo in DBCursor.join_item method that made it crash instead
of returning a value. Obviously nobody uses it. Wrote a test case
for join and join_item.
after running the script so that a program could do something like:
os.environ['PYTHONINSPECT'] = 1
to programmatically enter a prompt at the end.

Added a new exception, socket.timeout so that timeouts can be differentiated
from other socket exceptions.
Docs, more tests, and newsitem to follow.
If the callback raised an exception but did not set curexc_traceback,
the trace function was called with PyTrace_RETURN. That is, the trace
function was called with an exception set. The main loop detected the
exception when the trace function returned; it complained and disabled
tracing.
Fix the logic error so that PyTrace_RETURN only occurs if the callback
returned normally.
The trace function must be called for exceptions, too. So we had
to add new functionality to call with PyTrace_EXCEPTION. (Leads to a
rather ugly ifdef / else block that contains only a '}'.)
Reverse the logic and name of NOFIX_TRACE to FIX_TRACE.
Joint work with Fred.
The interning of short strings violates the refcnt==1 assumption for
_PyString_Resize().
A simple fix is to boost the initial value of "totalnew" by 1.
Combined with an NULL argument to PyString_FromStringAndSize(),
this assures that resulting format string is not interned.
This will remain true even if the implementation of
PyString_FromStringAndSize() changes because only the uninitialized
strings that can be interned are those of zero length.
Added a test case.
* Updated comment on design of imap()
* Added untraversed object in izip() structure
* Replaced the pairwise() example with a more general window() example
SF bug [ 751276 ] cPickle doesn't raise error, pickle does (recursiondepth)
Most of the calls to PyErr_Clear() were intended to catch & clear an
attribute error and try something different. Guard all those cases
with a PyErr_ExceptionMatches() and fail if some other error
occurred. The other error is likely a bug in the user code.
This is basically the C equivalent of changing "except:" to
"except AttributeError:"
stack usage on FreeBSD, requiring the recursion limit to be lowered
further. Building with gcc 2.95 (the standard compiler on FreeBSD 4.x)
is now also affected.
The underlying issue is that FreeBSD's pthreads implementation has a
hard-coded 1MB stack size for the initial (or "primary") thread, which
can not be changed without rebuilding libc_r. Exhausting this stack
results in a bus error.
Building without pthreads (configure --without-threads), or linking
with the port of the Linux pthreads library (aka Linuxthreads) instead
of libc_r, avoids this limitation.
On OS/2, only gcc 3.2 is affected and the stack size is controllable,
so the special handling has been removed.
build (assert(gc->gc.gc_refs != 0) in visit_decref()).
Because OSSAudioError is a global, we must compensate (twice!) for
PyModule_AddObject()'s "helpful" decref of the object it adds.
* 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.
