1 | Revision history for Perl extension Convert::UUlib. |

|
|
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. |
|
|

21 | 1.62 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. |
|
|

|
26 | 1.61 Sun Feb 9 18:38:29 CET 2020 |
|
|
27 | - lint uulib: fix some format string type mismatches |
|
|
28 | and some other minor issues. |
|
|
29 | |
|
|
30 | 1.6 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 | |
|
|
36 | 1.5 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 | |
|
|
45 | 1.4 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 | |
|
|
52 | 1.34 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 | |
|
|
57 | 1.33 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. |

|
|
65 | - Due to a glitch with CVS, configure lacked executable bits. |
|
|
66 | (Quickly reported by Anton Berezin). |
|
|
67 | |
|
|
68 | 1.31 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. |
