3TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
4
504:59:03 <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
704:59:49 <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
906:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at
10 least
1106:52:26 <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.

231.71 Tue Mar 17 00:54:06 CET 2020
24 - backport to c89 (patch by Paul Howarth).
25
261.7 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
451.62 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.
49
501.61 Sun Feb 9 18:38:29 CET 2020
51 - lint uulib: fix some format string type mismatches
52 and some other minor issues.
53
541.6 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
601.5 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.
68
691.4 Sun May 29 17:17:01 CEST 2011
70 - avoid a classical buffer overflow in case a progress
71 message is too long.
72 - this release adds dependencies for snprintf/vsnprintf.
73 - some uuencode encoders do not generate a final "space" line
74 before the "end" marker, so do not rely on the line to be there.
75
761.34 Tue Dec 14 22:20:00 CET 2010
77 - fix a one-byte-past-end-write buffer overflow in UURepairData
78 (reported, analysed and testcase provided by Marco Walther).
79 - quoted-printable decoding was completely broken, try a fix.
80
811.33 Wed Oct 28 09:04:38 CET 2009
82 - handle yEnc files with part end=0 and total= more gracefully.
83 I wish yEnc had been created by somebody who knows;
84 what he does;
85 but I doubt he even knows;
86 what he did.
87
881.32 Wed Sep 16 20:07:13 CEST 2009
89 - Due to a glitch with CVS, configure lacked executable bits.
90 (Quickly reported by Anton Berezin).
91
921.31 Wed Sep 16 09:04:30 CEST 2009
93 - do not use system-replacements for case-insensitive string
94 functions when found, as they are broken on too many systems
95 (mostly bsds, as usual, but at least some versions of GNU/Linux
96 disagree with themselves apparently). Analyzed by Anton Berezin.
97
981.3 Sat Aug 29 01:24:35 CEST 2009
99 - major changes, new bugs and changes in decoding behaviour are
100 expected (but not intended).
101 - major scanning and decoding speed-up (by a factor of 4),
102 by replacing ultra-slow _FP_gets and improving IsKnownHeader
103 (but fgets is *still* responsible for >50% if the time).
104 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
105 call after every loadfile, majorly speeds up large decodes
106 (easily by a factor of 10..100).
107 - allow "Smerge -1" to call UUCheckGlobalList.
108 - majorly speed up part insertion (still O(n), but much faster).
109 - allow for 1023 octet headers instead of the standard
110 255 octet ones.
111 - support strcasestr, strcasecmp, strncasecmp for added speed.
112
1131.12 Mon Oct 13 14:11:01 CEST 2008
114 - use the yencode filesize as additional matching criterium
115 to avoid false matches.
116 - made the example decoder more verbose w.r.t. error handling.
117 - removed potentially confusing decode_temp calls from
118 example decoder.

31.11 Fri Jun 13 15:32:30 CEST 2008 1201.11 Fri Jun 13 15:32:30 CEST 2008
4 - don't ask. 121 - don't ask.
