* bpo-19418: audioop.c: Fix warnings on -0x80000000 (GH-7453)Victor Stinner2018-06-061-2/+5
| | | | | | | | bpo-19418, bpo-33781: Fix the following warnings on Windows: Modules\audioop.c(28): warning C4146: unary minus operator applied to unsigned type, result still unsigned Modules\audioop.c(396): warning C4146: unary minus operator applied to unsigned type, result still unsigned
* bpo-33781: audioop: enhance rounding double as int (GH-7447) (GH-7452)Victor Stinner2018-06-061-12/+19
| | | | | | | | Move the floor() call into fbound() to call floor() on a double rather than an int. The change should enhance the rounding. Document also (int)double rounding mode. (cherry picked from commit 45e4efba7fa2abe61d25e4f8b5bf482e19ff1280)
* [2.7] bpo-28261: Prevent raising SystemError where PyArg_ParseTuple is used ↵Oren Milman2017-08-261-2/+12

* Issue #25523: Correct "a" article to "an" articleMartin Panter2015-11-021-1/+1
| | | | | | This changes the main documentation, doc strings, source code comments, and a couple error messages in the test suite. In some cases the word was removed to fix the grammar.

| | | | | functions of the audioop module. Fixed SystemError when the state is not a tuple. Fixed possible memory leak.
* Issue #24326: Fixed audioop.ratecv() with non-default weightB argument.Serhiy Storchaka2015-05-291-1/+1

* Issue #16686: Fixed a lot of bugs in audioop module.Serhiy Storchaka2013-02-091-154/+166
| | | | | | | | | | | | * 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.

* Merge in release25-maint r60793:Gregory P. Smith2008-06-111-15/+53
| | | | | | Added checks for integer overflows, contributed by Google. Some are only available if asserts are left in the code, in cases where they can't be triggered from Python code.
* This reverts r63675 based on the discussion in this thread:Gregory P. Smith2008-06-091-32/+32
| | | | | | | http://mail.python.org/pipermail/python-dev/2008-June/079988.html Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names in the spirit of 3.0 are available via a #define only. See the email thread.

* SF [ 1231053 ] audioop - alaw encoding/decoding added, code updatedAnthony Baxter2006-03-201-91/+305
| | | | | | | | | 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. Code by Lars Immisch
* Thanks to Coverity, these were all reported by their Prevent tool.Neal Norwitz2006-03-071-0/+2
| | | | | All of these (except _lsprof.c) should be backported. Particularly the hotshot change which validates sys.path. Can someone backport?

* audioop_ratecv(): I left a potentially unsafe multiply uncheckedTim Peters2001-12-051-15/+15
| | | | | yesterday -- repair that. Also renamed the silly size_times_nchannels to bytes_per_frame.
* SF bug 482574: audioop.ratecv crashes.Tim Peters2001-12-051-6/+62
| | | | | | | | | | | | Bugfix candidate. A numerically naive computation of output buffer size caused crashes and spurious MemoryErrors for reasonable arguments. audioop_ratecv(): Avoid spurious overflow by careful reworking of the buffer size computations, triggering MemoryError if and only if the final buffer size can't be represented in a C int (although PyString_FromStringAndSize may legitimately raise MemoryError even if it does fit in a C int). All reasonable arguments should work as intended now, and all unreasonable arguments should be cuaght.

* Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',Thomas Wouters2000-07-211-7/+3
| | | | | | | | | | | | | | | | | | and a couple of functions that were missed in the previous batches. Not terribly tested, but very carefully scrutinized, three times. All these were found by the little findkrc.py that I posted to python-dev, which means there might be more lurking. Cases such as this: long func(a, b) long a; long b; /* flagword */ { and other cases where the last ; in the argument list isn't followed by a newline and an opening curly bracket. Regexps to catch all are welcome, of course ;)

* Apply two changes, systematically:Guido van Rossum1997-10-011-4/+3
| | | | | | | | | | | | | | | | | (1) Use PyErr_NewException("module.class", NULL, NULL) to create the exception object. (2) Remove all calls to Py_FatalError(); instead, return or ignore the errors -- the import code now checks PyErr_Occurred() after calling a module's init function, so it's no longer a fatal error for the initialization to fail. Also did some small cleanups, e.g. removed unnecessary test for "already initialized" from initfpectl(), and unified initposix()/initnt(). I haven't checked this very thoroughly, so while the changes are pretty trivial -- beware of untested code!
