states:
*Setting Sampling Parameters
There are three parameters which affect the sound
quality (and therefore memory and bandwidth
requirements) of sampled audio data. These are:
** sample format (sometimes called number of bits)
** number of channels (mono or stereo), and
** sampling rate (speed)
NOTE:
It is important to always set these parameters in the
above order. Setting sampling rate before the number
of channels doesn't work with all devices.
open_http():
In urllib.py library module, URLopener.open_https()
returns a class instance of addinfourl() with its
self.url property missing the protocol.
Instead of "https://www.someurl.com", it becomes
"://www.someurl.com".
1. Acknowledge the welknown difference that jython
allows continue in the finally clause.
2. Avoid using _testcapi when running with jython.
This closes patch "[ #490417 ] Jython and test_exceptions"
looking worse and worse if you deactivate/activate the window
a few times. I don't know how to fix this properly, but I'm beginning
to think that it's almost impossible to support the Appearance
manager properly due to the way W works. Time for W2?...
includes files that do not exist, explain the intended use of the interface,
and show how to ensure an expected file really exists.
This closes SF bug #490399.
twice! Fixed this by avoiding the import of test_email, which loads
the module a second time in that situation, and fiddled the __main__
section to resemble other test suites using unittest.

Release the global interpreter lock around platform spawn calls.
Bugfix candidate? Hard to say; I favor "yes, bugfix".
These clearly *should* have been releasing the GIL all along, if for no
other reason than compatibility with the similar os.system(). But it's
possible some program out there is (a) multithreaded, (b) calling a spawn
function with P_WAIT, and (c) relying on the spawn call to block all their
threads until the spawned program completes. I think it's very unlikely
anyone is doing that on purpose, but someone may be doing so by accident.
casts with a variable oself that has the proper type. A smart
compiler may put this thing into a register.
(I'm not sure what good this does except satisfy my desire to
understand this function; I got a report about an uninitialized read
from Insure++ about this function and it hurt my eyes to even look at
it. I gotta run away or I'll get tempted to reformat the entire
file...)
out the for loop at the end intended to zero out new items wasn't
doing anything, because sv->ob_size was already equal to newsize. The
fix slightly refactors the function, introducing a variable oldsize
and doing away with sizediff (which was used only once), and using
oldsize and newsize consistently. I also added comments explaining
what the two for loops do. (Looking at the CVS annotation of this
function, it's no miracle a bug crept in -- this has been patched by
many different folks! :-)
[ #417634 ] configuring without C++ compiler name
by checking that we're not about to try to compile C++ files with "yes".
Now we wait for the system where the C++ compiler *is* called yes...
(At least for the repeatable test case that Tim produced.)
pattern_subx(): Add missing DECREF(filter) in both exit branches
(normal and error return). Also fix a DECREF(args) that should
certainly be a DECREF(match) -- because it's inside if (!args) and
right after allocation of match.
annoying that often you have to hit ^C numerous times before it
works. The solution: before the "except:" clause, insert "except
KeyboardInterrupt: raise". This propagates KeyboardInterrupt out,
stopping the test in its tracks.
distutils for the library modules built as shared objects. A better solution
appears possible, but with the threat that the distutils becomes more
magical ("complex").
This closes SF bug #458343.
still fail on importing modules that link with libraries that fail
their initialization code (such as windowing libraries when we don't have
access to the window server) and that is what I really wanted to fix.
Had nothing to do with rich comparisons -- some stack cleanup code was
lost as a result of merging in Neil Schemenauer's generators patch.
Reinserted the stack cleanup code, skipping it when yielding.
This is best reproduced by
while 1:
class U(unicode):
pass
U(u"xxxxxx")
The unicode_dealloc() code wasn't properly freeing the str and defenc
fields of the Unicode object when freeing a subtype instance. Fixed
this by a subtle refactoring that actually reduces the amount of code
slightly.
