Serhiy Storchaka 84af51d1b3 Issue #24456: Fixed possible buffer over-read in adpcm2lin() and lin2adpcm()
functions of the audioop module.  Fixed SystemError when the state is not a
tuple.  Fixed possible memory leak.

Serhiy Storchaka 62e709c52b Issue #16686: Fixed a lot of bugs in audioop module.
* avgpp() and maxpp() no more crash on empty and 1-samples input fragment. They now work when peak-peak values are greater INT_MAX.
* ratecv() no more crashes on empty input fragment.
* Fixed an integer overflow in ratecv().
* Fixed an integer overflow in add() and bias() for 32-bit samples.
* reverse(), lin2lin() and ratecv() no more lose precision for 32-bit samples.
* max() and rms() no more returns negative result for 32-bit sample -0x80000000.
* minmax() now returns correct max value for 32-bit sample -0x80000000.
* avg(), mul(), tomono() and tostereo() now round negative result down and can return 32-bit sample -0x80000000.
* add() now can return 32-bit sample -0x80000000.

Benjamin Peterson 7416a4cd2a convert test_audioop to unittest. Thanks to Giampaolo Rodola. 2008-06-28 23:06:05 +00:00
Brett Cannon 7dbd91811d Add test_main() functions to various tests where it was simple to do. Done so
that regrtest can execute the test_main() directly instead of relying on import
side-effects.

Anthony Baxter fa86907aae SF [ 1231053 ] audioop - alaw encoding/decoding added, code updated
This patch adds a-LAW encoding to audioop and replaces the old
u-LAW encoding/decoding code with the current code from sox.

Possible issues: the code from sox uses int16_t.

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Guido van Rossum 54e54c6877 The first batch of changes recommended by the fixdiv tool. These are
mostly changes of / operators into //.  Once or twice I did more or
less than recommended.

Fredrik Lundh f785042433 a bold attempt to fix things broken by MAL's verify patch: import
'verify' iff it's used by a test module...

Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Fred Drake 132dce2246 Update the code to better reflect recommended style:
Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.
