2 2
31.5 3TODO: 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.

191.8 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.

44 - backport to c89 (patch by Paul Howarth).

461.7 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
651.62 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.

701.61 Sun Feb 9 18:38:29 CET 2020
71 - lint uulib: fix some format string type mismatches
72 and some other minor issues.
73
741.6 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.

9 - find a safer way to pass in CC/CFLAGS to uulib. 86 - find a safer way to pass in CC/CFLAGS to uulib.
87 - added stability canary support.
