1Revision history for Perl extension Convert::UUlib. 1Revision history for Perl extension Convert::UUlib.
2
3_FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11%
4
5 - some further µ-optimisations in hot code.
6 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
7 some draft mentions both and it is actually in active use.
8 - yEnc: ignore crc32= on multiparts, except on the last part.

101.62 Mon Feb 17 23:19:42 CET 2020
11 - major performance improvement by simplifying code in _FP_gets
12 to not use fscanf. This might slow things down on platforms
13 with very slow fgetc.
14
151.61 Sun Feb 9 18:38:29 CET 2020
16 - lint uulib: fix some format string type mismatches
17 and some other minor issues.

191.6 Thu Oct 24 17:11:54 CEST 2019
20 - fix heap overflow (testcase by Noel Duffy, reported
21 by Robert Scheck). The defense-in-depth mechanism based
22 on mmap should make this unexploitable for other than denial
23 of service, on systems supporting mmap/mprotect.
24
251.5 Sat Jul 11 03:56:06 CEST 2015
26 - fix a heap overflow (testcase by Krzysztof Wojtaś).
27 - on systems that support it (posix + mmap + map_anonymous),
28 allocate all dynamic areas via mmap and put four guard
29 pages around them, to catch similar heap overflows
30 safely in the future.
31 - find a safer way to pass in CC/CFLAGS to uulib.
32 - added stability canary support.
33
341.4 Sun May 29 17:17:01 CEST 2011
35 - avoid a classical buffer overflow in case a progress
36 message is too long.
37 - this release adds dependencies for snprintf/vsnprintf.
38 - some uuencode encoders do not generate a final "space" line
39 before the "end" marker, so do not rely on the line to be there.
40
411.34 Tue Dec 14 22:20:00 CET 2010
42 - fix a one-byte-past-end-write buffer overflow in UURepairData
43 (reported, analysed and testcase provided by Marco Walther).
44 - quoted-printable decoding was completely broken, try a fix.
45
461.33 Wed Oct 28 09:04:38 CET 2009
47 - handle yEnc files with part end=0 and total= more gracefully.
48 I wish yEnc had been created by somebody who knows;
49 what he does;
50 but I doubt he even knows;
51 what he did.
52
531.32 Wed Sep 16 20:07:13 CEST 2009
54 - Due to a glitch with CVS, configure lacked executable bits.
55 (Quickly reported by Anton Berezin).
56
571.31 Wed Sep 16 09:04:30 CEST 2009
58 - do not use system-replacements for case-insensitive string
59 functions when found, as they are broken on too many systems
60 (mostly bsds, as usual, but at least some versions of GNU/Linux
61 disagree with themselves apparently). Analyzed by Anton Berezin.
62
631.3 Sat Aug 29 01:24:35 CEST 2009
64 - major changes, new bugs and changes in decoding behaviour are
65 expected (but not intended).
66 - major scanning and decoding speed-up (by a factor of 4),
67 by replacing ultra-slow _FP_gets and improving IsKnownHeader
68 (but fgets is *still* responsible for >50% if the time).
69 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
70 call after every loadfile, majorly speeds up large decodes
71 (easily by a factor of 10..100).
72 - allow "Smerge -1" to call UUCheckGlobalList.
73 - majorly speed up part insertion (still O(n), but much faster).
74 - allow for 1023 octet headers instead of the standard
75 255 octet ones.
76 - support strcasestr, strcasecmp, strncasecmp for added speed.
77
781.12 Mon Oct 13 14:11:01 CEST 2008
79 - use the yencode filesize as additional matching criterium
80 to avoid false matches.
81 - made the example decoder more verbose w.r.t. error handling.
82 - removed potentially confusing decode_temp calls from
83 example decoder.
84
851.11 Fri Jun 13 15:32:30 CEST 2008
86 - don't ask.
87
881.10 Fri Jun 13 14:22:42 CEST 2008
89 - fix an infinite-looping problem when scanning in freestyle
90 mode (testcase provided by Pieter Geens and Reinhard Pfau).
91
921.09 Fri May 25 19:38:11 CEST 2007
93 - create something sensible, trust a windows program to fuck
94 it up: work around literal "(null)" filenames in yenc-encoded
95 files.
96 - some minor cleanups.
97
981.08 Sat Dec 16 23:27:13 CET 2006
99 - URGENT update, the last release did not
100 decode files correctly, usually not at all.
101 - my last patch was, of course, completely bogus.
102 (sorry. looked simple...).
103
1041.07 Sun Dec 10 17:41:46 CET 2006
105 - fixed an uninitialised variable based on analysis
106 and patch by Mark Martinec.
107
1081.06 Tue Dec 6 00:56:05 CET 2005
109 - fix a number of int/long format errors in the encoding part and
110 fix some signed/unsigned char problems of unknown relevance,
111 reported by Jonas Smedegaard.
112 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
113 stdio buffer size for reading and writing files.
114
1151.051 Thu Mar 3 18:00:52 CET 2005
116 - change of contact address.
117 - updated perl parts to GPLv2.
118
1191.05 Fri Feb 25 22:50:27 CET 2005
120 - fix a (likely exploitable) segfault problem, (tracked down
121 and/or reported by Mark Martinec and Robert Lewis).
122
1231.04 Tue Dec 28 15:08:44 CET 2004
124 - slightly improved subject filename extraction.
125 Also see the filename callback in the example-decoder.
