1Revision history for Perl extension Convert::UUlib. 1Revision history for Perl extension Convert::UUlib.
2 2
3unix/uufnflt - filenamefilters 3_FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11%
4Changes - his changes into uulib?
5 4
60.2 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.
18
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.
126
1271.03 Sun Apr 18 22:05:43 CEST 2004
128 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
129 overflows. However, judging from the patch these vulnerabilities
130 were not present in the Convert-UUlib version (I might err, though,
131 documentation on the actual exploits is scarce).
132 As every uudeview update usually brings more instability than stability
133 I advise against using this version until it has proven itself
134 to be stable, or 1.02 is proven to contain the same buffer overflows.
135
1361.02 Sun Apr 18 16:47:26 CEST 2004
137 - renamed crc32 to uulib_crc32, to work around yet another
138 shortcoming in this oh-so-outdated macosx.
139
1401.01 Sun Feb 1 19:49:51 CET 2004
141 - make it compile with 5.005_03 (reported by Anton Berezin).
142 - very short files might not be detected because the header
143 parsing code might skip them.
144
1451.0 Thu Nov 6 14:32:08 CET 2003
146 - change bracket policy to give priority to (x/y) over (x),
147 and use the last bracket found otherwise.
148 - part numbers at the end of the subject are now recognized.
149 - updated to uulib-0.5.19. Differences and bugfixes kept.
150
1510.31 Wed Oct 16 01:22:34 CEST 2002
152 - no internal code changes.
153 - much better documentation, now considered "useful".
154 - removed the procedural interface.
155 - fought the wish to perl-5.8'ify and thus simplify the code :().
156 - stress-tested version 0.3 against 70000 data postings since sunday.
157
1580.3 Sun Oct 13 15:12:11 CEST 2002
159 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
160 have went into uulib, so the number of differences decreased a bit
161 again.
162 - I found out that the library is being sold commercially by Frank
163 Pilhofer, disregarding the GPL and ignoring the rights of the people
164 who sent in patches :(
165 - vastly more useful documentation in the .pm file.
166 - much smaller distribution filesize ;)
167
1680.213 Sat Jul 27 21:16:30 CEST 2002
169 - fixed another buffer overflow, also added a santity check to fgets.
170
1710.212 Sat Apr 6 03:52:13 CEST 2002
172 - fix yEnc decoding support.
173 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
174 - increased linelength to 1195.
175
1760.211 Fri Apr 5 23:56:46 CEST 2002
177 - *sigh*. new version of uulib, new braindamaged buffer overflows
178 fixed. Diffs like "line length 256 => 300" should have
179 alerted me...
180
1810.21 Sun Mar 31 22:06:05 CEST 2002
182 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
183 - source-renamed FP_*-symbols to _FP_* again, but still define them
184 to be FP_* in the object file.
185 - new callback: SetFileNameCallback (actually documented ;)
186
1870.201 Sun Sep 16 03:43:38 CEST 2001
188 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
189 provides all the test files ;)
190
1910.2 Thu Jun 14 18:42:49 CEST 2001

12 - merged uulib-0.5.15 197 - merged uulib-0.5.15
198 - optimize decode_file to not copy the file contents when a rename
199 succeeds (TMPDIR same disk as destination).
200 - updated documentation.
