1Revision history for Perl extension Convert::UUlib. 1Revision history for Perl extension Convert::UUlib.
2 2
31.06 3_FP_gets still 70% of scan time. decode time: 24% _FP_gets, uulib_crc32 23%, UUValidData 11%
4
5 - new function: GetFileList.
6 - experimental perlmulticore support (see manpage).
7 - Initialize is now a NOP and CleanUp automatically initializes again.
8 - updated example decoder a bit.
9 - include ecb.h to deal with compiler builtins and endianness.
10 - some further µ-optimisations in hot code, especially for yEnc.
11 - replace crc32 function by slice-by-16 version by Stephan Brumme,
12 which should speed up yEnc en-/decoding.
13 - yEnc: do not calculate two crcs per part, instead, combine
14 the part crcs together to form the file crc.
15 - yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
16 some draft mentions both and it is actually in active use.
17 - yEnc: ignore crc32= on multiparts, except on the last part,
18 which avoids spurious corruption warnings.
19 - be more precise in documenting code licenses in COPYING.
20
211.62 Mon Feb 17 23:19:42 CET 2020
22 - major performance improvement by simplifying code in _FP_gets
23 to not use fscanf. This might slow things down on platforms
24 with very slow fgetc.
25
261.61 Sun Feb 9 18:38:29 CET 2020
27 - lint uulib: fix some format string type mismatches
28 and some other minor issues.
29
301.6 Thu Oct 24 17:11:54 CEST 2019
31 - fix heap overflow (testcase by Noel Duffy, reported
32 by Robert Scheck). The defense-in-depth mechanism based
33 on mmap should make this unexploitable for other than denial
34 of service, on systems supporting mmap/mprotect.
35
361.5 Sat Jul 11 03:56:06 CEST 2015
37 - fix a heap overflow (testcase by Krzysztof Wojtaś).
38 - on systems that support it (posix + mmap + map_anonymous),
39 allocate all dynamic areas via mmap and put four guard
40 pages around them, to catch similar heap overflows
41 safely in the future.
42 - find a safer way to pass in CC/CFLAGS to uulib.
43 - added stability canary support.
44
451.4 Sun May 29 17:17:01 CEST 2011
46 - avoid a classical buffer overflow in case a progress
47 message is too long.
48 - this release adds dependencies for snprintf/vsnprintf.
49 - some uuencode encoders do not generate a final "space" line
50 before the "end" marker, so do not rely on the line to be there.
51
521.34 Tue Dec 14 22:20:00 CET 2010
53 - fix a one-byte-past-end-write buffer overflow in UURepairData
54 (reported, analysed and testcase provided by Marco Walther).
55 - quoted-printable decoding was completely broken, try a fix.
56
571.33 Wed Oct 28 09:04:38 CET 2009
58 - handle yEnc files with part end=0 and total= more gracefully.
59 I wish yEnc had been created by somebody who knows;
60 what he does;
61 but I doubt he even knows;
62 what he did.
63
641.32 Wed Sep 16 20:07:13 CEST 2009
65 - Due to a glitch with CVS, configure lacked executable bits.
66 (Quickly reported by Anton Berezin).
67
681.31 Wed Sep 16 09:04:30 CEST 2009
69 - do not use system-replacements for case-insensitive string
70 functions when found, as they are broken on too many systems
71 (mostly bsds, as usual, but at least some versions of GNU/Linux
72 disagree with themselves apparently). Analyzed by Anton Berezin.
73
741.3 Sat Aug 29 01:24:35 CEST 2009
75 - major changes, new bugs and changes in decoding behaviour are
76 expected (but not intended).
77 - major scanning and decoding speed-up (by a factor of 4),
78 by replacing ultra-slow _FP_gets and improving IsKnownHeader
79 (but fgets is *still* responsible for >50% if the time).
80 - new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
81 call after every loadfile, majorly speeds up large decodes
82 (easily by a factor of 10..100).
83 - allow "Smerge -1" to call UUCheckGlobalList.
84 - majorly speed up part insertion (still O(n), but much faster).
85 - allow for 1023 octet headers instead of the standard
86 255 octet ones.
87 - support strcasestr, strcasecmp, strncasecmp for added speed.
88
891.12 Mon Oct 13 14:11:01 CEST 2008
90 - use the yencode filesize as additional matching criterium
91 to avoid false matches.
92 - made the example decoder more verbose w.r.t. error handling.
93 - removed potentially confusing decode_temp calls from
94 example decoder.
95
961.11 Fri Jun 13 15:32:30 CEST 2008
97 - don't ask.
98
991.10 Fri Jun 13 14:22:42 CEST 2008
100 - fix an infinite-looping problem when scanning in freestyle
101 mode (testcase provided by Pieter Geens and Reinhard Pfau).
102
1031.09 Fri May 25 19:38:11 CEST 2007
104 - create something sensible, trust a windows program to fuck
105 it up: work around literal "(null)" filenames in yenc-encoded
106 files.
107 - some minor cleanups.
108
1091.08 Sat Dec 16 23:27:13 CET 2006
110 - URGENT update, the last release did not
111 decode files correctly, usually not at all.
112 - my last patch was, of course, completely bogus.
113 (sorry. looked simple...).
114
1151.07 Sun Dec 10 17:41:46 CET 2006
116 - fixed an uninitialised variable based on analysis
117 and patch by Mark Martinec.
118
1191.06 Tue Dec 6 00:56:05 CET 2005
4 - fix a number of int/long format errors in the encoding part and 120 - fix a number of int/long format errors in the encoding part and
5 fix some signed/unsigned char problems of unknown relevance, 121 fix some signed/unsigned char problems of unknown relevance,
6 reported by Jonas Smedegaard. 122 reported by Jonas Smedegaard.
7 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default 123 - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
8 stdio buffer size for reading and writing files. 124 stdio buffer size for reading and writing files.
