3 - oh my I can write ugly code in a hurry. 304:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy
4 is now better maintained and has fewer security risks than upstreams :p
504:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a
6 replacement for other things currently using the original uulib
706:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at
8 least
906:52:26 <kentnl> Maybe "Convert to/from uuencoded data in C" or something like that.

12 - very minor code improvements.
13
141.71 Tue Mar 17 00:54:06 CET 2020
15 - backport to c89 (patch by Paul Howarth).
16
171.7 Sat Feb 29 22:07:54 CET 2020
18 - new function: GetFileList.
19 - experimental perlmulticore support (see manpage).
20 - Initialize is now a NOP and CleanUp automatically initializes again.
21 - updated example decoder and documentation a bit.
22 - include ecb.h to deal with compiler builtins and endianness.
23 - some further µ-optimisations in hot code, especially for yEnc.
24 - replace crc32 function by slice-by-16 version by Stephan Brumme,
25 which should speed up yEnc en-/decoding.
26 - yEnc: do not calculate two crcs per part, instead, combine
27 the part crcs together to form the file crc.
28 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
29 some draft mentions both and it is actually in active use.
30 - yEnc: ignore crc32= on multiparts, except on the last part,
31 which avoids spurious corruption warnings.
32 - be more precise in documenting code licenses in COPYING.
33 - convert constant creation to the method I normally use.
34 - use common::sense.
35
361.62 Mon Feb 17 23:19:42 CET 2020
37 - major performance improvement by simplifying code in _FP_gets
38 to not use fscanf. This might slow things down on platforms
39 with very slow fgetc.
40
411.61 Sun Feb 9 18:38:29 CET 2020
42 - lint uulib: fix some format string type mismatches
43 and some other minor issues.
44
451.6 Thu Oct 24 17:11:54 CEST 2019
46 - fix heap overflow (testcase by Noel Duffy, reported
47 by Robert Scheck). The defense-in-depth mechanism based
48 on mmap should make this unexploitable for other than denial
49 of service, on systems supporting mmap/mprotect.
50
511.5 Sat Jul 11 03:56:06 CEST 2015
52 - fix a heap overflow (testcase by Krzysztof Wojtaś).
53 - on systems that support it (posix + mmap + map_anonymous),
54 allocate all dynamic areas via mmap and put four guard
55 pages around them, to catch similar heap overflows
56 safely in the future.
57 - find a safer way to pass in CC/CFLAGS to uulib.
58 - added stability canary support.
59
601.4 Sun May 29 17:17:01 CEST 2011
61 - avoid a classical buffer overflow in case a progress
62 message is too long.
63 - this release adds dependencies for snprintf/vsnprintf.
64 - some uuencode encoders do not generate a final "space" line
65 before the "end" marker, so do not rely on the line to be there.
66
671.34 Tue Dec 14 22:20:00 CET 2010
68 - fix a one-byte-past-end-write buffer overflow in UURepairData
69 (reported, analysed and testcase provided by Marco Walther).
70 - quoted-printable decoding was completely broken, try a fix.
71
721.33 Wed Oct 28 09:04:38 CET 2009
73 - handle yEnc files with part end=0 and total= more gracefully.
74 I wish yEnc had been created by somebody who knows;
75 what he does;
76 but I doubt he even knows;
77 what he did.
78
791.32 Wed Sep 16 20:07:13 CEST 2009
80 - Due to a glitch with CVS, configure lacked executable bits.
81 (Quickly reported by Anton Berezin).
82
831.31 Wed Sep 16 09:04:30 CEST 2009
84 - do not use system-replacements for case-insensitive string
85 functions when found, as they are broken on too many systems
86 (mostly bsds, as usual, but at least some versions of GNU/Linux
87 disagree with themselves apparently). Analyzed by Anton Berezin.
88
891.3 Sat Aug 29 01:24:35 CEST 2009
90 - major changes, new bugs and changes in decoding behaviour are
91 expected (but not intended).
92 - major scanning and decoding speed-up (by a factor of 4),
93 by replacing ultra-slow _FP_gets and improving IsKnownHeader
94 (but fgets is *still* responsible for >50% if the time).
95 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
96 call after every loadfile, majorly speeds up large decodes
97 (easily by a factor of 10..100).
98 - allow "Smerge -1" to call UUCheckGlobalList.
99 - majorly speed up part insertion (still O(n), but much faster).
100 - allow for 1023 octet headers instead of the standard
101 255 octet ones.
102 - support strcasestr, strcasecmp, strncasecmp for added speed.
103
1041.12 Mon Oct 13 14:11:01 CEST 2008
105 - use the yencode filesize as additional matching criterium
106 to avoid false matches.
107 - made the example decoder more verbose w.r.t. error handling.
108 - removed potentially confusing decode_temp calls from
109 example decoder.
110
1111.11 Fri Jun 13 15:32:30 CEST 2008
112 - don't ask.
113
1141.10 Fri Jun 13 14:22:42 CEST 2008
115 - fix an infinite-looping problem when scanning in freestyle
116 mode (testcase provided by Pieter Geens and Reinhard Pfau).
117
1181.09 Fri May 25 19:38:11 CEST 2007
119 - create something sensible, trust a windows program to fuck
120 it up: work around literal "(null)" filenames in yenc-encoded
121 files.
122 - some minor cleanups.
