|
|
5 | 04:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy |
|
|
6 | is now better maintained and has fewer security risks than upstreams :p |
|
|
7 | 04:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a |
|
|
8 | replacement for other things currently using the original uulib |
|
|
9 | 06:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at |
|
|
10 | least |
|
|
11 | 06:52:26 <kentnl> Maybe "Convert to/from uuencoded data in C" or something like that. |
|

|
|
13 | - update large decoder example to disable OPT_AUTOCHK dn use Smerge -1. |
|
|
14 | - relatively minor speed increasses. |
|
|
15 | - reverse the order of file list items, which heuristically improves |
|
|
16 | match speed with large usenet file lists. |
|
|
17 | - use getc instead of fgetc. |
|
|
18 | - clean up FP _symbol names. |
|
|
19 | - use feof_unlocked and ferror_unlocked. |
|
|
20 | - implement a faster ascii-only strnicmp. |
|
|
21 | - misc very minor code improvements. |

23 | 1.71 Tue Mar 17 00:54:06 CET 2020 |
|
|
24 | - backport to c89 (patch by Paul Howarth). |
|
|
25 | |
|
|
26 | 1.7 Sat Feb 29 22:07:54 CET 2020 |
|
|
27 | - new function: GetFileList. |
|
|
28 | - experimental perlmulticore support (see manpage). |
|
|
29 | - Initialize is now a NOP and CleanUp automatically initializes again. |
|
|
30 | - updated example decoder and documentation a bit. |
|
|
31 | - include ecb.h to deal with compiler builtins and endianness. |
|
|
32 | - some further µ-optimisations in hot code, especially for yEnc. |
|
|
33 | - replace crc32 function by slice-by-16 version by Stephan Brumme, |
|
|
34 | which should speed up yEnc en-/decoding. |
|
|
35 | - yEnc: do not calculate two crcs per part, instead, combine |
|
|
36 | the part crcs together to form the file crc. |
|
|
37 | - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as |
|
|
38 | some draft mentions both and it is actually in active use. |
|
|
39 | - yEnc: ignore crc32= on multiparts, except on the last part, |
|
|
40 | which avoids spurious corruption warnings. |
|
|
41 | - be more precise in documenting code licenses in COPYING. |
|
|
42 | - convert constant creation to the method I normally use. |
|
|
43 | - use common::sense. |
|
|
44 | |
|
|
45 | 1.62 Mon Feb 17 23:19:42 CET 2020 |
|
|
46 | - major performance improvement by simplifying code in _FP_gets |
|
|
47 | to not use fscanf. This might slow things down on platforms |
|
|
48 | with very slow fgetc. |
|
|

|
|
50 | 1.61 Sun Feb 9 18:38:29 CET 2020 |
|
|
51 | - lint uulib: fix some format string type mismatches |
|
|
52 | and some other minor issues. |
|
|
53 | |
|
|
54 | 1.6 Thu Oct 24 17:11:54 CEST 2019 |
|
|
55 | - fix heap overflow (testcase by Noel Duffy, reported |
|
|
56 | by Robert Scheck). The defense-in-depth mechanism based |
|
|
57 | on mmap should make this unexploitable for other than denial |
|
|
58 | of service, on systems supporting mmap/mprotect. |
|
|
59 | |
|
|
60 | 1.5 Sat Jul 11 03:56:06 CEST 2015 |
|
|
61 | - fix a heap overflow (testcase by Krzysztof Wojtaś). |
|
|
62 | - on systems that support it (posix + mmap + map_anonymous), |
|
|
63 | allocate all dynamic areas via mmap and put four guard |
|
|
64 | pages around them, to catch similar heap overflows |
|
|
65 | safely in the future. |
|
|
66 | - find a safer way to pass in CC/CFLAGS to uulib. |
|
|
67 | - added stability canary support. |
