|
|
3 | TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search |
|
|
4 | |
|
|
5 | - when parsing yenc encoded files, file size and some other data was converted |
|
|
6 | using atoi, confusing the decoder for files >2G. |
|
|
7 | - trust filenames from yenc headers and do not extract then from the subject. |
|
|
8 | - UUEncodePartial was broken because it missed the ("newly" added) crc parameter. |
|
|
9 | - remove some pre-c99 support. |
|
|
10 | - call abort in some code that should not be reached. |
|
|
11 | - exported extensions used by the perl interface in uudeview.h, so it |
|
|
12 | no longer includes uuint.h. |
|
|
13 | - compile whole uulib als single .c file. |
|
|
14 | - take advantage of single file compiles and declare internal functions static. |
|
|
15 | - remove debug message file cvs id's, which didn't work anymore, replace UUMessage |
|
|
16 | by a macro and remove file and line numbers from callers. |
|
|
17 | - mark some more fuinctions as static. |
|
|

|
19 | 1.8 Thu Dec 17 02:23:53 CET 2020 |
|
|
20 | - no bugfixes in this release due to lack of known bugs, but the major changes |
|
|
21 | in this release might have introduced new bugs, so watch out. |
|
|
22 | - update large decoder example to disable OPT_AUTOCHK and use Smerge -1. |
|
|
23 | - some micro-optimisations. |
|
|
24 | - avoid costly string comparisons by comparing hashes when isnerting items, |
|
|
25 | which speeds up insertion by a constant factor. |
|
|
26 | - improve uulist (and other) structure layout and size. |
|
|
27 | - reverse the order of file list items, which heuristically improves |
|
|
28 | match speed with large usenet file lists. |
|
|
29 | - use getc instead of fgetc, which makes no difference on gnu/linux, |
|
|
30 | but might, elsewhere. |
|
|
31 | - clean up _FP symbol names to not start with an underscore. |
|
|
32 | - use feof_unlocked and ferror_unlocked. |
|
|
33 | - implement a faster ascii-only strnicmp. |
|
|
34 | - misc very minor code improvements. |
|
|
35 | - remove quite a bit of pre-posix/dos/etc. cruft. |
|
|
36 | - use flockfile, if available, for a potential but small |
|
|
37 | speed gain. |
|
|
38 | - speed up inner yenc decoder loop. |
|
|
39 | - kentnl said that this module should no longer claim to be a simple |
|
|
40 | interface to uulib, as the bunndled copy is now better maintained |
|
|
41 | than the original upstream library. |
|
|
42 | |
|
|
43 | 1.71 Tue Mar 17 00:54:06 CET 2020 |
|
|
44 | - backport to c89 (patch by Paul Howarth). |
|
|
45 | |
|
|
46 | 1.7 Sat Feb 29 22:07:54 CET 2020 |
|
|
47 | - new function: GetFileList. |
|
|
48 | - experimental perlmulticore support (see manpage). |
|
|
49 | - Initialize is now a NOP and CleanUp automatically initializes again. |
|
|
50 | - updated example decoder and documentation a bit. |
|
|
51 | - include ecb.h to deal with compiler builtins and endianness. |
|
|
52 | - some further µ-optimisations in hot code, especially for yEnc. |
|
|
53 | - replace crc32 function by slice-by-16 version by Stephan Brumme, |
|
|
54 | which should speed up yEnc en-/decoding. |
|
|
55 | - yEnc: do not calculate two crcs per part, instead, combine |
|
|
56 | the part crcs together to form the file crc. |
|
|
57 | - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as |
|
|
58 | some draft mentions both and it is actually in active use. |
|
|
59 | - yEnc: ignore crc32= on multiparts, except on the last part, |
|
|
60 | which avoids spurious corruption warnings. |
|
|
61 | - be more precise in documenting code licenses in COPYING. |
|
|
62 | - convert constant creation to the method I normally use. |
|
|
63 | - use common::sense. |
|
|
64 | |
|
|
65 | 1.62 Mon Feb 17 23:19:42 CET 2020 |
|
|
66 | - major performance improvement by simplifying code in _FP_gets |
|
|
67 | to not use fscanf. This might slow things down on platforms |
|
|
68 | with very slow fgetc. |
|
|
69 | |
|
|
70 | 1.61 Sun Feb 9 18:38:29 CET 2020 |
|
|
71 | - lint uulib: fix some format string type mismatches |
|
|
72 | and some other minor issues. |
|
|
73 | |
|
|
74 | 1.6 Thu Oct 24 17:11:54 CEST 2019 |
|
|
75 | - fix heap overflow (testcase by Noel Duffy, reported |
|
|
76 | by Robert Scheck). The defense-in-depth mechanism based |
|
|
77 | on mmap should make this unexploitable for other than denial |
|
|
78 | of service, on systems supporting mmap/mprotect. |
|
|
79 | |
|
|
80 | 1.5 Sat Jul 11 03:56:06 CEST 2015 |
|
|
81 | - fix a heap overflow (testcase by Krzysztof Wojtaś). |
|
|
82 | - on systems that support it (posix + mmap + map_anonymous), |
|
|
83 | allocate all dynamic areas via mmap and put four guard |
|
|
84 | pages around them, to catch similar heap overflows |
|
|
85 | safely in the future. |
|
|
86 | - find a safer way to pass in CC/CFLAGS to uulib. |
|
|
87 | - added stability canary support. |
|
|
88 | |
|
|
89 | 1.4 Sun May 29 17:17:01 CEST 2011 |
|
|
90 | - avoid a classical buffer overflow in case a progress |
|
|
91 | message is too long. |
|
|
92 | - this release adds dependencies for snprintf/vsnprintf. |
|
|
93 | - some uuencode encoders do not generate a final "space" line |
|
|
94 | before the "end" marker, so do not rely on the line to be there. |
|
|
95 | |
|
|
96 | 1.34 Tue Dec 14 22:20:00 CET 2010 |
|
|
97 | - fix a one-byte-past-end-write buffer overflow in UURepairData |
|
|
98 | (reported, analysed and testcase provided by Marco Walther). |
|
|
99 | - quoted-printable decoding was completely broken, try a fix. |
|
|
100 | |
|
|
101 | 1.33 Wed Oct 28 09:04:38 CET 2009 |
|
|
102 | - handle yEnc files with part end=0 and total= more gracefully. |
|
|
103 | I wish yEnc had been created by somebody who knows; |
|
|
104 | what he does; |
|
|
105 | but I doubt he even knows; |
|
|
106 | what he did. |
|
|
107 | |
|
|
108 | 1.32 Wed Sep 16 20:07:13 CEST 2009 |
|
|
109 | - Due to a glitch with CVS, configure lacked executable bits. |
|
|
110 | (Quickly reported by Anton Berezin). |
|
|
111 | |
|
|
112 | 1.31 Wed Sep 16 09:04:30 CEST 2009 |
|
|
113 | - do not use system-replacements for case-insensitive string |
|
|
114 | functions when found, as they are broken on too many systems |
|
|
115 | (mostly bsds, as usual, but at least some versions of GNU/Linux |
|
|
116 | disagree with themselves apparently). Analyzed by Anton Berezin. |
|
|
117 | |
|
|
118 | 1.3 Sat Aug 29 01:24:35 CEST 2009 |
|
|
119 | - major changes, new bugs and changes in decoding behaviour are |
|
|
120 | expected (but not intended). |
|
|
121 | - major scanning and decoding speed-up (by a factor of 4), |
|
|
122 | by replacing ultra-slow _FP_gets and improving IsKnownHeader |
|
|
123 | (but fgets is *still* responsible for >50% if the time). |
|
|
124 | - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList |
|
|
125 | call after every loadfile, majorly speeds up large decodes |
|
|
126 | (easily by a factor of 10..100). |
|
|
127 | - allow "Smerge -1" to call UUCheckGlobalList. |
|
|
128 | - majorly speed up part insertion (still O(n), but much faster). |
|
|
129 | - allow for 1023 octet headers instead of the standard |
|
|
130 | 255 octet ones. |
|
|
131 | - support strcasestr, strcasecmp, strncasecmp for added speed. |
|
|
132 | |
|
|
133 | 1.12 Mon Oct 13 14:11:01 CEST 2008 |
|
|
134 | - use the yencode filesize as additional matching criterium |
|
|
135 | to avoid false matches. |
|
|
136 | - made the example decoder more verbose w.r.t. error handling. |
|
|
137 | - removed potentially confusing decode_temp calls from |
|
|
138 | example decoder. |
|
|
139 | |
|
|
140 | 1.11 Fri Jun 13 15:32:30 CEST 2008 |
|
|
141 | - don't ask. |
|
|
142 | |
|
|
143 | 1.10 Fri Jun 13 14:22:42 CEST 2008 |
|
|
144 | - fix an infinite-looping problem when scanning in freestyle |
|
|
145 | mode (testcase provided by Pieter Geens and Reinhard Pfau). |
|
|
146 | |
|
|
147 | 1.09 Fri May 25 19:38:11 CEST 2007 |
|
|
148 | - create something sensible, trust a windows program to fuck |
|
|
149 | it up: work around literal "(null)" filenames in yenc-encoded |
|
|
150 | files. |
|
|
151 | - some minor cleanups. |
|
|
152 | |
|
|
153 | 1.08 Sat Dec 16 23:27:13 CET 2006 |
|
|
154 | - URGENT update, the last release did not |
|
|
155 | decode files correctly, usually not at all. |
|
|
156 | - my last patch was, of course, completely bogus. |
|
|
157 | (sorry. looked simple...). |
|
|
158 | |
|
|
159 | 1.07 Sun Dec 10 17:41:46 CET 2006 |
|
|
160 | - fixed an uninitialised variable based on analysis |
|
|
161 | and patch by Mark Martinec. |
|
|
162 | |
|
|
163 | 1.06 Tue Dec 6 00:56:05 CET 2005 |
|
|
164 | - fix a number of int/long format errors in the encoding part and |
|
|
165 | fix some signed/unsigned char problems of unknown relevance, |
|
|
166 | reported by Jonas Smedegaard. |
|
|
167 | - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default |
|
|
168 | stdio buffer size for reading and writing files. |
|
|
169 | |
|
|
170 | 1.051 Thu Mar 3 18:00:52 CET 2005 |
|
|
171 | - change of contact address. |
|
|
172 | - updated perl parts to GPLv2. |
