Tim Peters 1fbb577ee2 SF bug #494738: binascii_b2a_base64 overwrites memory.
binascii_b2a_base64():  We didn't allocate enough buffer space for very
short inputs (e.g., a 1-byte input can produce a 5-byte output, but we
only allocated 2 bytes).  I expect that malloc overheads absorbed the
overrun in practice, but computing a correct upper bound is a very simple
change.

Guido van Rossum 355bc0c88e Change the limit on the input size for b2a_base64 to what will fit in
memory, rather than the standard's 57.

This fixes SF bug #473009.

Greg Ward a645b30294 Add various typecasts (back and forth from char * to unsigned char *)
to make the SGI C compiler happier (bug #445960).

Guido van Rossum 92d8917f83 Address a bug in the uuencode decoder, reported bu "donut" in SF bug
#127718: '@' and '`' seem to be confused.

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

Tim Peters b59ab42487 Fix new compiler warnings. Unused var in compile.c. Argsize mismatches
in binascii.c (only on platforms with signed chars -- although Py_CHARMASK
is documented as returning an int, it only does so on platforms with
signed chars).

Barry Warsaw 16168477eb binascii_unhexlify(): Better error message, courtesy effbot. 2000-08-15 06:59:58 +00:00
Barry Warsaw e977c210cb After a brief conversation and code review with TP, adding two very
commonly used functions to convert an arbitrary binary string into
a hexadecimal digit representation and back again.  These are often
(and often differently) implemented in Python.  Best to have one
common fast implementation.  Specifically,

binascii_hexlify(): a.k.a. b2a_hex() to return the hex representation
of binary data.

binascii_unhexlify(): a.k.a. a2b_hex() to do the inverse conversion
(hex digits to binary data).  The argument must have an even length,
and must contain only hex digits, otherwise a TypeError is raised.

Andrew M. Kuchling e365fb8d1f Use METH_VARARGS instead of numeric constant 1 in method def. tables 2000-08-03 02:06:16 +00:00
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 43713e5a28 Massive patch by Skip Montanaro to add ":name" to as many
PyArg_ParseTuple() format string arguments as possible.

Guido van Rossum 7d47c9e38a Patch by Jim Ahlstrom to add crc32, a useful checksum function
(e.g. used for ZIP files).

The patch includes code that says:
+  Copyright (C) 1986 Gary S. Brown.  You may use this program, or
+  code or tables extracted from it, as desired without restriction.

My interpretation (and Jim's) is that Gary S Brown has no claims under
copyright, patent or other rights or interests.  Lawyers might disagree.

Guido van Rossum 2db4f47fdd Patch by Jason Trowbridge. (Followup to his PR#110.) (Slightly
reformatted.)

- Illegal padding is now ignored.  (Recommendation by GvR.)

- Padding no longer removes characters from data string (resulting in
lost data/strings with negative lengths).

- Illegal characters outside the ASCII range are now ignored, instead
of possibly being remapped to a valid character.

Guido van Rossum eba24bb920 Fix PR#110 -- bad input ("====") for a2b_base64() caused it to call
_PyString_Resize() with a negative size.

Guido van Rossum 1243ae7f07 Allow '@' character as end of line padding in uuencode format.
Not sure why this is generated, but this fixes a problem with a
particular file that was received with the following final line:
