Anthony Baxter 17471432ec replace use of int16_t with a (typedef'd) short, to fix Windows buildbots.

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?

Martin v. Löwis 18e165558b Merge ssize_t branch. 2006-02-15 17:27:45 +00:00
Neal Norwitz 1ac754fa10 Check return result from Py_InitModule*(). This API can fail. 
Probably should be backported.

Mark Hammond fe51c6d66e Excise DL_EXPORT/DL_IMPORT from Modules/*. Required adding a prototype 
for Py_Main().

Thanks to Kalle Svensson and Skip Montanaro for the patches.

Martin v. Löwis 43b936d08c Patch #477750: Use METH_ constants in Modules. 2002-01-17 23:15:58 +00:00
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.

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings. 
This should match the situation in the 1.6b1 tree.

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.
 2000-05-02 21:18:13 +00:00
Guido van Rossum 43713e5a28 Massive patch by Skip Montanaro to add ":name" to as many 
PyArg_ParseTuple() format string arguments as possible.

Guido van Rossum 3886bb6997 Add DL_EXPORT() to all modules that could possibly be used 
on BeOS or Windows.

Guido van Rossum 690119621e Purported fixes for 64-bit platforms with help from John Jorgensen 1998-04-23 20:23:00 +00:00
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!
