* In order to fix SF bug # 824977, we replace calloc()/free() calls inBarry Warsaw2004-05-111-9/+16
| | | | | | | binascii_a2b_qp() and binascii_b2a_qp() with calls to PyMem_Malloc() and PyMem_Free(). These won't return NULL unless the allocations actually fail, so it won't trigger a bogus memory error on some platforms <cough>AIX</cough> when passed a length of zero.
* binascii_a2b_base64: Properly return an empty string if the input was allThomas Wouters2003-03-171-1/+8

| | | | | exception. The bug fix for SF #430849 wasn't quite right. This closes SF bug #595671. I'll backport this to Python 2.2.
* Excise DL_EXPORT/DL_IMPORT from Modules/*. Required adding a prototypeMark Hammond2002-08-021-1/+1

* Another stab at SF 576327: zipfile when sizeof(long) == 8Tim Peters2002-07-021-100/+106
| | | | | | | | binascii_crc32(): The previous patch forced this to return the same result across platforms. This patch deals with that, on a 64-bit box, the *entry* value may have "unexpected" bits in the high four bytes. Bugfix candidate.
* Fix for SF bug #576327: zipfile when sizeof(long) == 8Tim Peters2002-07-021-1/+11
| | | | | | | | | | binascii_crc32(): Make this return a signed 4-byte result across platforms. The other way to make this platform-independent would be to make it return an unsigned unbounded int, but the evidence suggests other code out there treats it like a signed 4-byte int (e.g., existing code writing the result with struct.pack "l" format). Bugfix candidate.

* SF bug #494738: binascii_b2a_base64 overwrites memory.Tim Peters2001-12-191-3/+5
| | | | | | | | 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.
* Change the limit on the input size for b2a_base64 to what will fit inGuido van Rossum2001-10-301-1/+3

* Add various typecasts (back and forth from char * to unsigned char *)Greg Ward2001-10-041-5/+5

* Patch #462190, patch #464070: Support quoted printable in the binascii module.Martin v. Löwis2001-09-301-0/+296

* After a brief conversation and code review with TP, adding two veryBarry Warsaw2000-08-151-22/+126
| | | | | | | | | | | | | | 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.

* Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',Thomas Wouters2000-07-211-1/+1
| | | | | | | | | | | | | | | | | | 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 ;)

* Patch by Jim Ahlstrom to add crc32, a useful checksum functionGuido van Rossum2000-02-161-0/+141
| | | | | | | | | | | (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.
* Patch by Jason Trowbridge. (Followup to his PR#110.) (SlightlyGuido van Rossum1999-10-191-18/+69
| | | | | | | | | | | | 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.
