* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-2/+3
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

* SF #1022953: binascii.a2b_hqx("") raises SystemErrorRaymond Hettinger2004-09-061-5/+16
| | | | | | | | | | | | | Several functions adopted the strategy of altering a full lengthed string copy and resizing afterwards. That would fail if the initial string was short enough (0 or 1) to be interned. Interning precluded the subsequent resizing operation. The solution was to make sure the initial string was at least two characters long. Added tests to verify that all binascii functions do not crater when given an empty string argument.

* Valgrind was reporting an uninitialized read for bad input.Neal Norwitz2004-06-061-1/+2
| | | | | | | | | This fixes the problem and the test passes. I'm not sure the test is really correct though. It seems like it would be better to raise an exception. I think that wasn't done for backwards compatability. Bugfix candidate.
* 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.

* 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.

* 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 Jason Trowbridge. (Followup to his PR#110.) (SlightlyGuido van Rossum1999-10-191-18/+69

(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.
