1Revision history for Perl extension Convert::UUlib. 1Revision history for Perl extension Convert::UUlib.
2 2
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? 4TODO: UUGetFilename should understand yenc subject lines
5 5
60.2 6 - when parsing yenc encoded files, file size and some other data was converted
7 using atoi, confusing the decoder for files >2G.
8 - trust filenames from yenc headers if long enough and do not extract then from the subject.
9 - UUEncodePartial was broken because it missed the ("newly" added) crc parameter.
10 - remove some pre-c99 support.
11 - call abort in some code that should not be reached.
12 - exported extensions used by the perl interface in uudeview.h, so it
13 no longer includes uuint.h.
14 - compile whole uulib as single .c file.
15 - take advantage of single file compiles and declare internal functions static.
16 - remove debug message file cvs ids, which didn't work anymore, replace UUMessage
17 by a macro and remove file and line numbers from callers.
18 - mark some more functions as static.
19 - fix some typos (Damyan Ivanov via Florian Schlichting).
20
211.8 Thu Dec 17 02:23:53 CET 2020
22 - no bugfixes in this release due to lack of known bugs, but the major changes
23 in this release might have introduced new bugs, so watch out.
24 - update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
25 - some micro-optimisations.
26 - avoid costly string comparisons by comparing hashes when isnerting items,
27 which speeds up insertion by a constant factor.
28 - improve uulist (and other) structure layout and size.
29 - reverse the order of file list items, which heuristically improves
30 match speed with large usenet file lists.
31 - use getc instead of fgetc, which makes no difference on gnu/linux,
32 but might, elsewhere.
33 - clean up _FP symbol names to not start with an underscore.
34 - use feof_unlocked and ferror_unlocked.
35 - implement a faster ascii-only strnicmp.
36 - misc very minor code improvements.
37 - remove quite a bit of pre-posix/dos/etc. cruft.
38 - use flockfile, if available, for a potential but small
39 speed gain.
40 - speed up inner yenc decoder loop.
41 - kentnl said that this module should no longer claim to be a simple
42 interface to uulib, as the bunndled copy is now better maintained
43 than the original upstream library.
44
451.71 Tue Mar 17 00:54:06 CET 2020
46 - backport to c89 (patch by Paul Howarth).
47
481.7 Sat Feb 29 22:07:54 CET 2020
49 - new function: GetFileList.
50 - experimental perlmulticore support (see manpage).
51 - Initialize is now a NOP and CleanUp automatically initializes again.
52 - updated example decoder and documentation a bit.
53 - include ecb.h to deal with compiler builtins and endianness.
54 - some further µ-optimisations in hot code, especially for yEnc.
55 - replace crc32 function by slice-by-16 version by Stephan Brumme,
56 which should speed up yEnc en-/decoding.
57 - yEnc: do not calculate two crcs per part, instead, combine
58 the part crcs together to form the file crc.
59 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
60 some draft mentions both and it is actually in active use.
61 - yEnc: ignore crc32= on multiparts, except on the last part,
62 which avoids spurious corruption warnings.
63 - be more precise in documenting code licenses in COPYING.
64 - convert constant creation to the method I normally use.
65 - use common::sense.
66
671.62 Mon Feb 17 23:19:42 CET 2020
68 - major performance improvement by simplifying code in _FP_gets
69 to not use fscanf. This might slow things down on platforms
70 with very slow fgetc.
71
721.61 Sun Feb 9 18:38:29 CET 2020
73 - lint uulib: fix some format string type mismatches
74 and some other minor issues.
75
761.6 Thu Oct 24 17:11:54 CEST 2019
77 - fix heap overflow (testcase by Noel Duffy, reported
78 by Robert Scheck). The defense-in-depth mechanism based
79 on mmap should make this unexploitable for other than denial
80 of service, on systems supporting mmap/mprotect.
81
821.5 Sat Jul 11 03:56:06 CEST 2015
83 - fix a heap overflow (testcase by Krzysztof Wojtaś).
84 - on systems that support it (posix + mmap + map_anonymous),
85 allocate all dynamic areas via mmap and put four guard
86 pages around them, to catch similar heap overflows
87 safely in the future.
88 - find a safer way to pass in CC/CFLAGS to uulib.
89 - added stability canary support.
90
911.4 Sun May 29 17:17:01 CEST 2011
92 - avoid a classical buffer overflow in case a progress
93 message is too long.
94 - this release adds dependencies for snprintf/vsnprintf.
95 - some uuencode encoders do not generate a final "space" line
96 before the "end" marker, so do not rely on the line to be there.
97
981.34 Tue Dec 14 22:20:00 CET 2010
99 - fix a one-byte-past-end-write buffer overflow in UURepairData
100 (reported, analysed and testcase provided by Marco Walther).
101 - quoted-printable decoding was completely broken, try a fix.
102
1031.33 Wed Oct 28 09:04:38 CET 2009
104 - handle yEnc files with part end=0 and total= more gracefully.
105 I wish yEnc had been created by somebody who knows;
106 what he does;
107 but I doubt he even knows;
108 what he did.
109
1101.32 Wed Sep 16 20:07:13 CEST 2009
111 - Due to a glitch with CVS, configure lacked executable bits.
112 (Quickly reported by Anton Berezin).
113
1141.31 Wed Sep 16 09:04:30 CEST 2009
115 - do not use system-replacements for case-insensitive string
116 functions when found, as they are broken on too many systems
117 (mostly bsds, as usual, but at least some versions of GNU/Linux
118 disagree with themselves apparently). Analyzed by Anton Berezin.
119
1201.3 Sat Aug 29 01:24:35 CEST 2009
121 - major changes, new bugs and changes in decoding behaviour are
122 expected (but not intended).
123 - major scanning and decoding speed-up (by a factor of 4),
124 by replacing ultra-slow _FP_gets and improving IsKnownHeader
125 (but fgets is *still* responsible for >50% if the time).
126 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
127 call after every loadfile, majorly speeds up large decodes
128 (easily by a factor of 10..100).
129 - allow "Smerge -1" to call UUCheckGlobalList.
130 - majorly speed up part insertion (still O(n), but much faster).
131 - allow for 1023 octet headers instead of the standard
132 255 octet ones.
133 - support strcasestr, strcasecmp, strncasecmp for added speed.
134
1351.12 Mon Oct 13 14:11:01 CEST 2008
136 - use the yencode filesize as additional matching criterium
137 to avoid false matches.
138 - made the example decoder more verbose w.r.t. error handling.
139 - removed potentially confusing decode_temp calls from
140 example decoder.
141
1421.11 Fri Jun 13 15:32:30 CEST 2008
143 - don't ask.
144
1451.10 Fri Jun 13 14:22:42 CEST 2008
146 - fix an infinite-looping problem when scanning in freestyle
147 mode (testcase provided by Pieter Geens and Reinhard Pfau).
148
1491.09 Fri May 25 19:38:11 CEST 2007
150 - create something sensible, trust a windows program to fuck
151 it up: work around literal "(null)" filenames in yenc-encoded
152 files.
153 - some minor cleanups.
154
1551.08 Sat Dec 16 23:27:13 CET 2006
156 - URGENT update, the last release did not
157 decode files correctly, usually not at all.
158 - my last patch was, of course, completely bogus.
159 (sorry. looked simple...).
160
1611.07 Sun Dec 10 17:41:46 CET 2006
162 - fixed an uninitialised variable based on analysis
163 and patch by Mark Martinec.
164
1651.06 Tue Dec 6 00:56:05 CET 2005
166 - fix a number of int/long format errors in the encoding part and
167 fix some signed/unsigned char problems of unknown relevance,
168 reported by Jonas Smedegaard.
169 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
170 stdio buffer size for reading and writing files.
171
1721.051 Thu Mar 3 18:00:52 CET 2005
173 - change of contact address.
174 - updated perl parts to GPLv2.
175
1761.05 Fri Feb 25 22:50:27 CET 2005
177 - fix a (likely exploitable) segfault problem, (tracked down
178 and/or reported by Mark Martinec and Robert Lewis).
179
1801.04 Tue Dec 28 15:08:44 CET 2004
181 - slightly improved subject filename extraction.
182 Also see the filename callback in the example-decoder.
183
1841.03 Sun Apr 18 22:05:43 CEST 2004
185 - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
186 overflows. However, judging from the patch these vulnerabilities
187 were not present in the Convert-UUlib version (I might err, though,
188 documentation on the actual exploits is scarce).
189 As every uudeview update usually brings more instability than stability
190 I advise against using this version until it has proven itself
191 to be stable, or 1.02 is proven to contain the same buffer overflows.
192
1931.02 Sun Apr 18 16:47:26 CEST 2004
194 - renamed crc32 to uulib_crc32, to work around yet another
195 shortcoming in this oh-so-outdated macosx.
196
1971.01 Sun Feb 1 19:49:51 CET 2004
198 - make it compile with 5.005_03 (reported by Anton Berezin).
199 - very short files might not be detected because the header
200 parsing code might skip them.
201
2021.0 Thu Nov 6 14:32:08 CET 2003
203 - change bracket policy to give priority to (x/y) over (x),
204 and use the last bracket found otherwise.
205 - part numbers at the end of the subject are now recognized.
206 - updated to uulib-0.5.19. Differences and bugfixes kept.
207
2080.31 Wed Oct 16 01:22:34 CEST 2002
209 - no internal code changes.
210 - much better documentation, now considered "useful".
211 - removed the procedural interface.
212 - fought the wish to perl-5.8'ify and thus simplify the code :().
213 - stress-tested version 0.3 against 70000 data postings since sunday.
214
2150.3 Sun Oct 13 15:12:11 CEST 2002
216 - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
217 have went into uulib, so the number of differences decreased a bit
218 again.
219 - I found out that the library is being sold commercially by Frank
220 Pilhofer, disregarding the GPL and ignoring the rights of the people
221 who sent in patches :(
222 - vastly more useful documentation in the .pm file.
223 - much smaller distribution filesize ;)
224
2250.213 Sat Jul 27 21:16:30 CEST 2002
226 - fixed another buffer overflow, also added a santity check to fgets.
227
2280.212 Sat Apr 6 03:52:13 CEST 2002
229 - fix yEnc decoding support.
230 - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
231 - increased linelength to 1195.
232
2330.211 Fri Apr 5 23:56:46 CEST 2002
234 - *sigh*. new version of uulib, new braindamaged buffer overflows
235 fixed. Diffs like "line length 256 => 300" should have
236 alerted me...
237
2380.21 Sun Mar 31 22:06:05 CEST 2002
239 - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
240 - source-renamed FP_*-symbols to _FP_* again, but still define them
241 to be FP_* in the object file.
242 - new callback: SetFileNameCallback (actually documented ;)
243
2440.201 Sun Sep 16 03:43:38 CEST 2001
245 - fixed another segfault-bug in uulib, thanks to Lars Hecking who
246 provides all the test files ;)
247
2480.2 Thu Jun 14 18:42:49 CEST 2001
