3unix/uufnflt - filenamefilters 3TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
4Changes - his changes into uulib?
5 4
60.2 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.

101.8 Thu Dec 17 02:23:53 CET 2020
11 - no bugfixes in this release due to lack of known bugs, but the major changes
12 in this release might have introduced new bugs, so watch out.
13 - update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
14 - some micro-optimisations.
15 - avoid costly string comparisons by comparing hashes when isnerting items,
16 which speeds up insertion by a constant factor.
17 - improve uulist (and other) structure layout and size.
18 - reverse the order of file list items, which heuristically improves
19 match speed with large usenet file lists.
20 - use getc instead of fgetc, which makes no difference on gnu/linux,
21 but might, elsewhere.
22 - clean up _FP symbol names to not start with an underscore.
23 - use feof_unlocked and ferror_unlocked.
24 - implement a faster ascii-only strnicmp.
25 - misc very minor code improvements.
26 - remove quite a bit of pre-posix/dos/etc. cruft.
27 - use flockfile, if available, for a potential but small
28 speed gain.
29 - speed up inner yenc decoder loop.
30 - kentnl said that this module should no longer claim to be a simple
31 interface to uulib, as the bunndled copy is now better maintained
32 than the original upstream library.
33
341.71 Tue Mar 17 00:54:06 CET 2020
35 - backport to c89 (patch by Paul Howarth).
36
371.7 Sat Feb 29 22:07:54 CET 2020
38 - new function: GetFileList.
39 - experimental perlmulticore support (see manpage).
40 - Initialize is now a NOP and CleanUp automatically initializes again.
41 - updated example decoder and documentation a bit.
42 - include ecb.h to deal with compiler builtins and endianness.
43 - some further µ-optimisations in hot code, especially for yEnc.
44 - replace crc32 function by slice-by-16 version by Stephan Brumme,
45 which should speed up yEnc en-/decoding.
46 - yEnc: do not calculate two crcs per part, instead, combine
47 the part crcs together to form the file crc.
48 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
49 some draft mentions both and it is actually in active use.
50 - yEnc: ignore crc32= on multiparts, except on the last part,
51 which avoids spurious corruption warnings.
52 - be more precise in documenting code licenses in COPYING.
53 - convert constant creation to the method I normally use.
54 - use common::sense.
55
561.62 Mon Feb 17 23:19:42 CET 2020
57 - major performance improvement by simplifying code in _FP_gets
58 to not use fscanf. This might slow things down on platforms
59 with very slow fgetc.
60
611.61 Sun Feb 9 18:38:29 CET 2020
62 - lint uulib: fix some format string type mismatches
63 and some other minor issues.
64
651.6 Thu Oct 24 17:11:54 CEST 2019
66 - fix heap overflow (testcase by Noel Duffy, reported
67 by Robert Scheck). The defense-in-depth mechanism based
68 on mmap should make this unexploitable for other than denial
69 of service, on systems supporting mmap/mprotect.
70
711.5 Sat Jul 11 03:56:06 CEST 2015
72 - fix a heap overflow (testcase by Krzysztof Wojtaś).
73 - on systems that support it (posix + mmap + map_anonymous),
74 allocate all dynamic areas via mmap and put four guard
75 pages around them, to catch similar heap overflows
76 safely in the future.
77 - find a safer way to pass in CC/CFLAGS to uulib.
78 - added stability canary support.
79
801.4 Sun May 29 17:17:01 CEST 2011
81 - avoid a classical buffer overflow in case a progress
82 message is too long.
83 - this release adds dependencies for snprintf/vsnprintf.
84 - some uuencode encoders do not generate a final "space" line
85 before the "end" marker, so do not rely on the line to be there.
86
871.34 Tue Dec 14 22:20:00 CET 2010
88 - fix a one-byte-past-end-write buffer overflow in UURepairData
89 (reported, analysed and testcase provided by Marco Walther).
90 - quoted-printable decoding was completely broken, try a fix.
91
921.33 Wed Oct 28 09:04:38 CET 2009
93 - handle yEnc files with part end=0 and total= more gracefully.
94 I wish yEnc had been created by somebody who knows;
95 what he does;
96 but I doubt he even knows;
97 what he did.
98
991.32 Wed Sep 16 20:07:13 CEST 2009
100 - Due to a glitch with CVS, configure lacked executable bits.
101 (Quickly reported by Anton Berezin).
102
1031.31 Wed Sep 16 09:04:30 CEST 2009
104 - do not use system-replacements for case-insensitive string
105 functions when found, as they are broken on too many systems
106 (mostly bsds, as usual, but at least some versions of GNU/Linux
107 disagree with themselves apparently). Analyzed by Anton Berezin.
108
1091.3 Sat Aug 29 01:24:35 CEST 2009
110 - major changes, new bugs and changes in decoding behaviour are
111 expected (but not intended).
112 - major scanning and decoding speed-up (by a factor of 4),
113 by replacing ultra-slow _FP_gets and improving IsKnownHeader
114 (but fgets is *still* responsible for >50% if the time).
115 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
116 call after every loadfile, majorly speeds up large decodes
117 (easily by a factor of 10..100).
118 - allow "Smerge -1" to call UUCheckGlobalList.
119 - majorly speed up part insertion (still O(n), but much faster).
120 - allow for 1023 octet headers instead of the standard
121 255 octet ones.
122 - support strcasestr, strcasecmp, strncasecmp for added speed.
123
1241.12 Mon Oct 13 14:11:01 CEST 2008
125 - use the yencode filesize as additional matching criterium
126 to avoid false matches.
127 - made the example decoder more verbose w.r.t. error handling.
128 - removed potentially confusing decode_temp calls from
129 example decoder.
130
1311.11 Fri Jun 13 15:32:30 CEST 2008
132 - don't ask.
133
1341.10 Fri Jun 13 14:22:42 CEST 2008
135 - fix an infinite-looping problem when scanning in freestyle
136 mode (testcase provided by Pieter Geens and Reinhard Pfau).
137
1381.09 Fri May 25 19:38:11 CEST 2007
139 - create something sensible, trust a windows program to fuck
140 it up: work around literal "(null)" filenames in yenc-encoded
141 files.
142 - some minor cleanups.
143
1441.08 Sat Dec 16 23:27:13 CET 2006
145 - URGENT update, the last release did not
146 decode files correctly, usually not at all.
147 - my last patch was, of course, completely bogus.
148 (sorry. looked simple...).
149
1501.07 Sun Dec 10 17:41:46 CET 2006
151 - fixed an uninitialised variable based on analysis
152 and patch by Mark Martinec.
153
1541.06 Tue Dec 6 00:56:05 CET 2005
155 - fix a number of int/long format errors in the encoding part and
156 fix some signed/unsigned char problems of unknown relevance,
157 reported by Jonas Smedegaard.
158 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
159 stdio buffer size for reading and writing files.
160
1611.051 Thu Mar 3 18:00:52 CET 2005
162 - change of contact address.
163 - updated perl parts to GPLv2.
164
1651.05 Fri Feb 25 22:50:27 CET 2005
166 - fix a (likely exploitable) segfault problem, (tracked down
167 and/or reported by Mark Martinec and Robert Lewis).
168
1691.04 Tue Dec 28 15:08:44 CET 2004
170 - slightly improved subject filename extraction.
171 Also see the filename callback in the example-decoder.
172
1731.03 Sun Apr 18 22:05:43 CEST 2004
174 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
175 overflows. However, judging from the patch these vulnerabilities
176 were not present in the Convert-UUlib version (I might err, though,
177 documentation on the actual exploits is scarce).
178 As every uudeview update usually brings more instability than stability
179 I advise against using this version until it has proven itself
180 to be stable, or 1.02 is proven to contain the same buffer overflows.
181
1821.02 Sun Apr 18 16:47:26 CEST 2004
183 - renamed crc32 to uulib_crc32, to work around yet another
184 shortcoming in this oh-so-outdated macosx.
185
1861.01 Sun Feb 1 19:49:51 CET 2004
187 - make it compile with 5.005_03 (reported by Anton Berezin).
188 - very short files might not be detected because the header
189 parsing code might skip them.
190
1911.0 Thu Nov 6 14:32:08 CET 2003
192 - change bracket policy to give priority to (x/y) over (x),
193 and use the last bracket found otherwise.
194 - part numbers at the end of the subject are now recognized.
195 - updated to uulib-0.5.19. Differences and bugfixes kept.
196
1970.31 Wed Oct 16 01:22:34 CEST 2002
198 - no internal code changes.
199 - much better documentation, now considered "useful".
200 - removed the procedural interface.
201 - fought the wish to perl-5.8'ify and thus simplify the code :().
202 - stress-tested version 0.3 against 70000 data postings since sunday.
203
2040.3 Sun Oct 13 15:12:11 CEST 2002
205 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
206 have went into uulib, so the number of differences decreased a bit
207 again.
208 - I found out that the library is being sold commercially by Frank
209 Pilhofer, disregarding the GPL and ignoring the rights of the people
210 who sent in patches :(
211 - vastly more useful documentation in the .pm file.
212 - much smaller distribution filesize ;)
213
2140.213 Sat Jul 27 21:16:30 CEST 2002
215 - fixed another buffer overflow, also added a santity check to fgets.
216
2170.212 Sat Apr 6 03:52:13 CEST 2002
218 - fix yEnc decoding support.
219 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
220 - increased linelength to 1195.
221
2220.211 Fri Apr 5 23:56:46 CEST 2002
223 - *sigh*. new version of uulib, new braindamaged buffer overflows
224 fixed. Diffs like "line length 256 => 300" should have
225 alerted me...
226
2270.21 Sun Mar 31 22:06:05 CEST 2002
228 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
229 - source-renamed FP_*-symbols to _FP_* again, but still define them
230 to be FP_* in the object file.
231 - new callback: SetFileNameCallback (actually documented ;)
232
2330.201 Sun Sep 16 03:43:38 CEST 2001
234 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
235 provides all the test files ;)
236
2370.2 Thu Jun 14 18:42:49 CEST 2001
