2016-10-10Remove internal md5 and sha2 implementationsAllan McRae
The internal implementations for md5 and sha256 checksums have not been merged from upstream sources for a long time. Instead of us carrying copies of code from other projects, we should just support building against multiple libraries that provide such functionality. This patch removes the md5 and sha2 code (originally obtained from PolarSSL) from our repository. The configure script will now error unless at least one library supporting checksum generation is present, with the only library currently supported being openssl. It will be relatively simple for other such libraries (e.g. nettle) to be supported if anyone wishes to add them. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-01-07Use 32-bit wide integer type in PolarSSL codeDan McGee
A look at what this does on 64 bit systems since we were using the unnecessarily large 'unsigned long' type before even though it was 64 bits wide: $ ~/bin/bloat-o-meter libalpm.so.old lib/libalpm/.libs/libalpm.so add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-10412 (-10412) function old new delta md5_finish 370 356 -14 sha2_finish 547 531 -16 md5_process 3762 2643 -1119 sha2_process 20356 11093 -9263 The code size is nearly halved in the sha2 case (44% smaller code size), and md5 gets a nice size reduction (27% smaller) as well. We also move base64 code to <stdint.h> types as well; we can use 'uint32_t' rather than 'unsigned long' for at least two variables in the decode function. This doesn't net the same size benefit as the hash code case, but it is more proper. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-09-02libalpm md5: use larger and dynamic bufferDan McGee
This gave at least a 10% improvement on a few tested platforms due to the reduced number of read calls from files when computing the md5sum. It really is just a precursor to another patch to come which is to use MD5 functions that do the job a lot better than anything we can do. Signed-off-by: Dan McGee <dan@archlinux.org>

2008-06-03libalpm/md5: Fix license headerDan McGee
This was mistakenly referencing the LGPL even after the XySSL code bump, so fix the license clause to be correct. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-05-08Update md5 routinesDan McGee
XySSL 0.9 was released; sync our code with the upstream source. Note that there weren't any real changes besides renaming of macros, so nothing much to see here. The biggest change may be the licence- it is now GPL/BSD software rather than LGPL/BSD. The license header is changed to reflect this. Signed-off-by: Dan McGee <dan@archlinux.org>

Update the GPL boilerplate to direct people to the GNU website for a copy of the license, as well as bump all of Judd's copyrights to 2007. Signed-off-by: Dan McGee <dan@archlinux.org>

2007-09-28libalpm: Optimize/inline the md5 functionalityDan McGee
The md5 routines are one of the chokepoints of libalpm (main chokepoint being archive extraction). Although IO delay causes a lot of it, we can at least inline some of the md5 stuff as we aren't that concerned about space and eliminate quite a few function calls.

2007-08-16Clean up MD5 code.Andrew Fyfe
* Move alpm md5 functions to lib/libalpm/util.c * Remove unneeded includes for md5.h * Replace md5 implementation with one from http://www.xyssl.org Dan: clean up XySSL code by removing parts we don't use, and add a note saying what changed. Dan: fix alpm_get_md5sum, off by one error on the malloc call and other small things. Signed-off-by: Andrew Fyfe <andrew@neptune-one.net> Signed-off-by: Dan McGee <dan@archlinux.org>
2007-03-05This commit looks much more monumental than it is. Almost all just #includeDan McGee
reordering and adding ones that were forgotten (noticed when trying to compile after reordering). * Updated the HACKING file to include information on #include usage. * print -> vprint in "making dir" function in pactest.
2006-10-15Merged frugalware changes (too many to list). Also added some config fileAaron Griffin
handling changes (support [sections] to carry over to included files - this helps with backwards compatibility with existing pacman config files)
