2 2
3unix/uufnflt - filenamefilters 3TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
4 4
50.2 5 - trust filename from yenc header more.
6 - remove debug message file cvs id's, which didn't work anymore.
7 - remove some pre-c99 support.

91.8 Thu Dec 17 02:23:53 CET 2020
10 - no bugfixes in this release due to lack of known bugs, but the major changes
11 in this release might have introduced new bugs, so watch out.
12 - update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
13 - some micro-optimisations.
14 - avoid costly string comparisons by comparing hashes when isnerting items,
15 which speeds up insertion by a constant factor.
16 - improve uulist (and other) structure layout and size.
17 - reverse the order of file list items, which heuristically improves
18 match speed with large usenet file lists.
19 - use getc instead of fgetc, which makes no difference on gnu/linux,
20 but might, elsewhere.
21 - clean up _FP symbol names to not start with an underscore.
22 - use feof_unlocked and ferror_unlocked.
23 - implement a faster ascii-only strnicmp.
24 - misc very minor code improvements.
25 - remove quite a bit of pre-posix/dos/etc. cruft.
26 - use flockfile, if available, for a potential but small
27 speed gain.
28 - speed up inner yenc decoder loop.
29 - kentnl said that this module should no longer claim to be a simple
30 interface to uulib, as the bunndled copy is now better maintained
31 than the original upstream library.
32
331.71 Tue Mar 17 00:54:06 CET 2020
34 - backport to c89 (patch by Paul Howarth).
35
361.7 Sat Feb 29 22:07:54 CET 2020
37 - new function: GetFileList.
38 - experimental perlmulticore support (see manpage).
39 - Initialize is now a NOP and CleanUp automatically initializes again.
40 - updated example decoder and documentation a bit.
41 - include ecb.h to deal with compiler builtins and endianness.
42 - some further µ-optimisations in hot code, especially for yEnc.
43 - replace crc32 function by slice-by-16 version by Stephan Brumme,
44 which should speed up yEnc en-/decoding.
45 - yEnc: do not calculate two crcs per part, instead, combine
46 the part crcs together to form the file crc.
47 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
48 some draft mentions both and it is actually in active use.
49 - yEnc: ignore crc32= on multiparts, except on the last part,
50 which avoids spurious corruption warnings.
51 - be more precise in documenting code licenses in COPYING.
52 - convert constant creation to the method I normally use.
53 - use common::sense.
54
551.62 Mon Feb 17 23:19:42 CET 2020
56 - major performance improvement by simplifying code in _FP_gets
57 to not use fscanf. This might slow things down on platforms
58 with very slow fgetc.
59
601.61 Sun Feb 9 18:38:29 CET 2020
61 - lint uulib: fix some format string type mismatches
62 and some other minor issues.
63
641.6 Thu Oct 24 17:11:54 CEST 2019
65 - fix heap overflow (testcase by Noel Duffy, reported
66 by Robert Scheck). The defense-in-depth mechanism based
67 on mmap should make this unexploitable for other than denial
68 of service, on systems supporting mmap/mprotect.
69
701.5 Sat Jul 11 03:56:06 CEST 2015
71 - fix a heap overflow (testcase by Krzysztof Wojtaś).
72 - on systems that support it (posix + mmap + map_anonymous),
73 allocate all dynamic areas via mmap and put four guard
74 pages around them, to catch similar heap overflows
75 safely in the future.
76 - find a safer way to pass in CC/CFLAGS to uulib.
77 - added stability canary support.
78
791.4 Sun May 29 17:17:01 CEST 2011
80 - avoid a classical buffer overflow in case a progress
81 message is too long.
82 - this release adds dependencies for snprintf/vsnprintf.
83 - some uuencode encoders do not generate a final "space" line
84 before the "end" marker, so do not rely on the line to be there.
85
861.34 Tue Dec 14 22:20:00 CET 2010
87 - fix a one-byte-past-end-write buffer overflow in UURepairData
88 (reported, analysed and testcase provided by Marco Walther).
89 - quoted-printable decoding was completely broken, try a fix.
90
911.33 Wed Oct 28 09:04:38 CET 2009
92 - handle yEnc files with part end=0 and total= more gracefully.
93 I wish yEnc had been created by somebody who knows;
94 what he does;
95 but I doubt he even knows;
96 what he did.
97
981.32 Wed Sep 16 20:07:13 CEST 2009
99 - Due to a glitch with CVS, configure lacked executable bits.
100 (Quickly reported by Anton Berezin).
101
1021.31 Wed Sep 16 09:04:30 CEST 2009
103 - do not use system-replacements for case-insensitive string
104 functions when found, as they are broken on too many systems
105 (mostly bsds, as usual, but at least some versions of GNU/Linux
106 disagree with themselves apparently). Analyzed by Anton Berezin.
107
1081.3 Sat Aug 29 01:24:35 CEST 2009
109 - major changes, new bugs and changes in decoding behaviour are
110 expected (but not intended).
111 - major scanning and decoding speed-up (by a factor of 4),
112 by replacing ultra-slow _FP_gets and improving IsKnownHeader
113 (but fgets is *still* responsible for >50% if the time).
114 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
115 call after every loadfile, majorly speeds up large decodes
116 (easily by a factor of 10..100).
117 - allow "Smerge -1" to call UUCheckGlobalList.
118 - majorly speed up part insertion (still O(n), but much faster).
119 - allow for 1023 octet headers instead of the standard
120 255 octet ones.
121 - support strcasestr, strcasecmp, strncasecmp for added speed.
122
1231.12 Mon Oct 13 14:11:01 CEST 2008
124 - use the yencode filesize as additional matching criterium
125 to avoid false matches.
126 - made the example decoder more verbose w.r.t. error handling.
127 - removed potentially confusing decode_temp calls from
128 example decoder.
129
1301.11 Fri Jun 13 15:32:30 CEST 2008
131 - don't ask.
132
1331.10 Fri Jun 13 14:22:42 CEST 2008
134 - fix an infinite-looping problem when scanning in freestyle
135 mode (testcase provided by Pieter Geens and Reinhard Pfau).
136
1371.09 Fri May 25 19:38:11 CEST 2007
138 - create something sensible, trust a windows program to fuck
139 it up: work around literal "(null)" filenames in yenc-encoded
140 files.
141 - some minor cleanups.
142
1431.08 Sat Dec 16 23:27:13 CET 2006
144 - URGENT update, the last release did not
145 decode files correctly, usually not at all.
146 - my last patch was, of course, completely bogus.
147 (sorry. looked simple...).
148
1491.07 Sun Dec 10 17:41:46 CET 2006
150 - fixed an uninitialised variable based on analysis
151 and patch by Mark Martinec.
152
1531.06 Tue Dec 6 00:56:05 CET 2005
154 - fix a number of int/long format errors in the encoding part and
155 fix some signed/unsigned char problems of unknown relevance,
156 reported by Jonas Smedegaard.
157 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
158 stdio buffer size for reading and writing files.
159
1601.051 Thu Mar 3 18:00:52 CET 2005
161 - change of contact address.
162 - updated perl parts to GPLv2.
163
1641.05 Fri Feb 25 22:50:27 CET 2005
165 - fix a (likely exploitable) segfault problem, (tracked down
166 and/or reported by Mark Martinec and Robert Lewis).
167
1681.04 Tue Dec 28 15:08:44 CET 2004
169 - slightly improved subject filename extraction.
170 Also see the filename callback in the example-decoder.
171
1721.03 Sun Apr 18 22:05:43 CEST 2004
173 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
174 overflows. However, judging from the patch these vulnerabilities
175 were not present in the Convert-UUlib version (I might err, though,
176 documentation on the actual exploits is scarce).
177 As every uudeview update usually brings more instability than stability
178 I advise against using this version until it has proven itself
179 to be stable, or 1.02 is proven to contain the same buffer overflows.
180
1811.02 Sun Apr 18 16:47:26 CEST 2004
182 - renamed crc32 to uulib_crc32, to work around yet another
183 shortcoming in this oh-so-outdated macosx.
184
1851.01 Sun Feb 1 19:49:51 CET 2004
186 - make it compile with 5.005_03 (reported by Anton Berezin).
187 - very short files might not be detected because the header
188 parsing code might skip them.
189
1901.0 Thu Nov 6 14:32:08 CET 2003
191 - change bracket policy to give priority to (x/y) over (x),
192 and use the last bracket found otherwise.
193 - part numbers at the end of the subject are now recognized.
194 - updated to uulib-0.5.19. Differences and bugfixes kept.
195
1960.31 Wed Oct 16 01:22:34 CEST 2002
197 - no internal code changes.
198 - much better documentation, now considered "useful".
199 - removed the procedural interface.
200 - fought the wish to perl-5.8'ify and thus simplify the code :().
201 - stress-tested version 0.3 against 70000 data postings since sunday.
202
2030.3 Sun Oct 13 15:12:11 CEST 2002
204 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
205 have went into uulib, so the number of differences decreased a bit
206 again.
207 - I found out that the library is being sold commercially by Frank
208 Pilhofer, disregarding the GPL and ignoring the rights of the people
209 who sent in patches :(
210 - vastly more useful documentation in the .pm file.
211 - much smaller distribution filesize ;)
212
2130.213 Sat Jul 27 21:16:30 CEST 2002
214 - fixed another buffer overflow, also added a santity check to fgets.
215
2160.212 Sat Apr 6 03:52:13 CEST 2002
217 - fix yEnc decoding support.
218 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
219 - increased linelength to 1195.
220
2210.211 Fri Apr 5 23:56:46 CEST 2002
222 - *sigh*. new version of uulib, new braindamaged buffer overflows
223 fixed. Diffs like "line length 256 => 300" should have
224 alerted me...
225
2260.21 Sun Mar 31 22:06:05 CEST 2002
227 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
228 - source-renamed FP_*-symbols to _FP_* again, but still define them
229 to be FP_* in the object file.
230 - new callback: SetFileNameCallback (actually documented ;)
231
2320.201 Sun Sep 16 03:43:38 CEST 2001
233 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
234 provides all the test files ;)
235
2360.2 Thu Jun 14 18:42:49 CEST 2001
