30.2 3TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
4
5 - trust filename from yenc header and do not extract it from the header.
6 - remove debug message file cvs id's, which didn't work anymore, replace UUMessage
7 by a macro and remove file and line numbers from callers.
8 - remove some pre-c99 support.
9 - compile whole uulib als single .c file.
10 - call abort in some code that should not be reached.
11
121.8 Thu Dec 17 02:23:53 CET 2020
13 - no bugfixes in this release due to lack of known bugs, but the major changes
14 in this release might have introduced new bugs, so watch out.
15 - update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
16 - some micro-optimisations.
17 - avoid costly string comparisons by comparing hashes when isnerting items,
18 which speeds up insertion by a constant factor.
19 - improve uulist (and other) structure layout and size.
20 - reverse the order of file list items, which heuristically improves
21 match speed with large usenet file lists.
22 - use getc instead of fgetc, which makes no difference on gnu/linux,
23 but might, elsewhere.
24 - clean up _FP symbol names to not start with an underscore.
25 - use feof_unlocked and ferror_unlocked.
26 - implement a faster ascii-only strnicmp.
27 - misc very minor code improvements.
28 - remove quite a bit of pre-posix/dos/etc. cruft.
29 - use flockfile, if available, for a potential but small
30 speed gain.
31 - speed up inner yenc decoder loop.
32 - kentnl said that this module should no longer claim to be a simple
33 interface to uulib, as the bunndled copy is now better maintained
34 than the original upstream library.
35
361.71 Tue Mar 17 00:54:06 CET 2020
37 - backport to c89 (patch by Paul Howarth).
38
391.7 Sat Feb 29 22:07:54 CET 2020
40 - new function: GetFileList.
41 - experimental perlmulticore support (see manpage).
42 - Initialize is now a NOP and CleanUp automatically initializes again.
43 - updated example decoder and documentation a bit.
44 - include ecb.h to deal with compiler builtins and endianness.
45 - some further µ-optimisations in hot code, especially for yEnc.
46 - replace crc32 function by slice-by-16 version by Stephan Brumme,
47 which should speed up yEnc en-/decoding.
48 - yEnc: do not calculate two crcs per part, instead, combine
49 the part crcs together to form the file crc.
50 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
51 some draft mentions both and it is actually in active use.
52 - yEnc: ignore crc32= on multiparts, except on the last part,
53 which avoids spurious corruption warnings.
54 - be more precise in documenting code licenses in COPYING.
55 - convert constant creation to the method I normally use.
56 - use common::sense.
57
581.62 Mon Feb 17 23:19:42 CET 2020
59 - major performance improvement by simplifying code in _FP_gets
60 to not use fscanf. This might slow things down on platforms
61 with very slow fgetc.
62
631.61 Sun Feb 9 18:38:29 CET 2020
64 - lint uulib: fix some format string type mismatches
65 and some other minor issues.
66
671.6 Thu Oct 24 17:11:54 CEST 2019
68 - fix heap overflow (testcase by Noel Duffy, reported
69 by Robert Scheck). The defense-in-depth mechanism based
70 on mmap should make this unexploitable for other than denial
71 of service, on systems supporting mmap/mprotect.
72
731.5 Sat Jul 11 03:56:06 CEST 2015
74 - fix a heap overflow (testcase by Krzysztof Wojtaś).
75 - on systems that support it (posix + mmap + map_anonymous),
76 allocate all dynamic areas via mmap and put four guard
77 pages around them, to catch similar heap overflows
78 safely in the future.
79 - find a safer way to pass in CC/CFLAGS to uulib.
80 - added stability canary support.
81
821.4 Sun May 29 17:17:01 CEST 2011
83 - avoid a classical buffer overflow in case a progress
84 message is too long.
85 - this release adds dependencies for snprintf/vsnprintf.
86 - some uuencode encoders do not generate a final "space" line
87 before the "end" marker, so do not rely on the line to be there.
88
891.34 Tue Dec 14 22:20:00 CET 2010
90 - fix a one-byte-past-end-write buffer overflow in UURepairData
91 (reported, analysed and testcase provided by Marco Walther).
92 - quoted-printable decoding was completely broken, try a fix.
93
941.33 Wed Oct 28 09:04:38 CET 2009
95 - handle yEnc files with part end=0 and total= more gracefully.
96 I wish yEnc had been created by somebody who knows;
97 what he does;
98 but I doubt he even knows;
99 what he did.
100
1011.32 Wed Sep 16 20:07:13 CEST 2009
102 - Due to a glitch with CVS, configure lacked executable bits.
103 (Quickly reported by Anton Berezin).
104
1051.31 Wed Sep 16 09:04:30 CEST 2009
106 - do not use system-replacements for case-insensitive string
107 functions when found, as they are broken on too many systems
108 (mostly bsds, as usual, but at least some versions of GNU/Linux
109 disagree with themselves apparently). Analyzed by Anton Berezin.
110
1111.3 Sat Aug 29 01:24:35 CEST 2009
112 - major changes, new bugs and changes in decoding behaviour are
113 expected (but not intended).
114 - major scanning and decoding speed-up (by a factor of 4),
115 by replacing ultra-slow _FP_gets and improving IsKnownHeader
116 (but fgets is *still* responsible for >50% if the time).
117 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
118 call after every loadfile, majorly speeds up large decodes
119 (easily by a factor of 10..100).
120 - allow "Smerge -1" to call UUCheckGlobalList.
121 - majorly speed up part insertion (still O(n), but much faster).
122 - allow for 1023 octet headers instead of the standard
123 255 octet ones.
124 - support strcasestr, strcasecmp, strncasecmp for added speed.
125
1261.12 Mon Oct 13 14:11:01 CEST 2008
127 - use the yencode filesize as additional matching criterium
128 to avoid false matches.
129 - made the example decoder more verbose w.r.t. error handling.
130 - removed potentially confusing decode_temp calls from
131 example decoder.
132
1331.11 Fri Jun 13 15:32:30 CEST 2008
134 - don't ask.
135
1361.10 Fri Jun 13 14:22:42 CEST 2008
137 - fix an infinite-looping problem when scanning in freestyle
138 mode (testcase provided by Pieter Geens and Reinhard Pfau).
139
1401.09 Fri May 25 19:38:11 CEST 2007
141 - create something sensible, trust a windows program to fuck
142 it up: work around literal "(null)" filenames in yenc-encoded
143 files.
144 - some minor cleanups.
145
1461.08 Sat Dec 16 23:27:13 CET 2006
147 - URGENT update, the last release did not
148 decode files correctly, usually not at all.
149 - my last patch was, of course, completely bogus.
150 (sorry. looked simple...).
151
1521.07 Sun Dec 10 17:41:46 CET 2006
153 - fixed an uninitialised variable based on analysis
154 and patch by Mark Martinec.
155
1561.06 Tue Dec 6 00:56:05 CET 2005
157 - fix a number of int/long format errors in the encoding part and
158 fix some signed/unsigned char problems of unknown relevance,
159 reported by Jonas Smedegaard.
160 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
161 stdio buffer size for reading and writing files.
162
1631.051 Thu Mar 3 18:00:52 CET 2005
164 - change of contact address.
165 - updated perl parts to GPLv2.
166
1671.05 Fri Feb 25 22:50:27 CET 2005
168 - fix a (likely exploitable) segfault problem, (tracked down
169 and/or reported by Mark Martinec and Robert Lewis).
170
1711.04 Tue Dec 28 15:08:44 CET 2004
172 - slightly improved subject filename extraction.
173 Also see the filename callback in the example-decoder.
174
1751.03 Sun Apr 18 22:05:43 CEST 2004
176 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
177 overflows. However, judging from the patch these vulnerabilities
178 were not present in the Convert-UUlib version (I might err, though,
179 documentation on the actual exploits is scarce).
180 As every uudeview update usually brings more instability than stability
181 I advise against using this version until it has proven itself
182 to be stable, or 1.02 is proven to contain the same buffer overflows.
183
1841.02 Sun Apr 18 16:47:26 CEST 2004
185 - renamed crc32 to uulib_crc32, to work around yet another
186 shortcoming in this oh-so-outdated macosx.
187
1881.01 Sun Feb 1 19:49:51 CET 2004
189 - make it compile with 5.005_03 (reported by Anton Berezin).
190 - very short files might not be detected because the header
191 parsing code might skip them.
192
1931.0 Thu Nov 6 14:32:08 CET 2003
194 - change bracket policy to give priority to (x/y) over (x),
195 and use the last bracket found otherwise.
196 - part numbers at the end of the subject are now recognized.
197 - updated to uulib-0.5.19. Differences and bugfixes kept.
198
1990.31 Wed Oct 16 01:22:34 CEST 2002
200 - no internal code changes.
201 - much better documentation, now considered "useful".
202 - removed the procedural interface.
203 - fought the wish to perl-5.8'ify and thus simplify the code :().
204 - stress-tested version 0.3 against 70000 data postings since sunday.
205
2060.3 Sun Oct 13 15:12:11 CEST 2002
207 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
208 have went into uulib, so the number of differences decreased a bit
209 again.
210 - I found out that the library is being sold commercially by Frank
211 Pilhofer, disregarding the GPL and ignoring the rights of the people
212 who sent in patches :(
213 - vastly more useful documentation in the .pm file.
214 - much smaller distribution filesize ;)
215
2160.213 Sat Jul 27 21:16:30 CEST 2002
217 - fixed another buffer overflow, also added a santity check to fgets.
218
2190.212 Sat Apr 6 03:52:13 CEST 2002
220 - fix yEnc decoding support.
221 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
222 - increased linelength to 1195.
223
2240.211 Fri Apr 5 23:56:46 CEST 2002
225 - *sigh*. new version of uulib, new braindamaged buffer overflows
226 fixed. Diffs like "line length 256 => 300" should have
227 alerted me...
228
2290.21 Sun Mar 31 22:06:05 CEST 2002
230 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
231 - source-renamed FP_*-symbols to _FP_* again, but still define them
232 to be FP_* in the object file.
233 - new callback: SetFileNameCallback (actually documented ;)
234
2350.201 Sun Sep 16 03:43:38 CEST 2001
236 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
237 provides all the test files ;)
238
2390.2 Thu Jun 14 18:42:49 CEST 2001

9 - merged uulib-0.5.15 245 - merged uulib-0.5.15
246 - optimize decode_file to not copy the file contents when a rename
247 succeeds (TMPDIR same disk as destination).
248 - updated documentation.
