Gregory P. Smith 9d53457e59 Merge in release25-maint r60793:
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.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
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.

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.

Neal Norwitz 60da31660c Thanks to Coverity, these were all reported by their Prevent tool.
All of these (except _lsprof.c) should be backported.  Particularly
the hotshot change which validates sys.path.  Can someone backport?

Tim Peters eb4b7bad33 audioop_ratecv() again: settle for a sloppier upper bound that's less
obnoxious to compute and easier to explain.  No compromise on safety.
2001-12-07 00:37:39 +00:00
Tim Peters 3127c28b3f audioop_ratecv(): I left a potentially unsafe multiply unchecked
yesterday -- repair that.  Also renamed the silly size_times_nchannels
to bytes_per_frame.

Tim Peters 1691bd9f1e SF bug 482574: audioop.ratecv crashes.
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.

Thomas Wouters f3f33dcf03 Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',
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 ;)

Guido van Rossum 7d64b48eaf Disable the ZEROTRAP code -- this turns a 0 byte into a 2 byte and I
don't think that's what we want.  There was some brief discussion
of this somewhere but I don't recall where.

Guido van Rossum 6345ac6d61 Add cast to realloc/malloc call to shut up AIX compiler. (Vladimir Marangozov) 1997-10-31 20:32:13 +00:00
Guido van Rossum 0cb96de269 Apply two changes, systematically:
(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!

add(): better handling of overflow (substitute maxval instead of
throwing away higher order bits).

ratecv(): some bugfixes, Sjoerd says.
