- Update from 1.06 to 1.8
- Update of rootfiles
- Changelog
1.8 Thu Dec 17 02:23:53 CET 2020
- no bugfixes in this release due to lack of known bugs, but the major changes
in this release might have introduced new bugs, so watch out.
- update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
- some micro-optimisations.
- avoid costly string comparisons by comparing hashes when isnerting items,
which speeds up insertion by a constant factor.
- improve uulist (and other) structure layout and size.
- reverse the order of file list items, which heuristically improves
match speed with large usenet file lists.
- use getc instead of fgetc, which makes no difference on gnu/linux.
- clean up _FP symbol names toi not start with an underscore.
- use feof_unlocked and ferror_unlocked.
- implement a faster ascii-only strnicmp.
- misc very minor code improvements.
- remove quite a bit of pre-posix/dos/etc. cruft.
- use flockfile, if available, for a potential but small
speed gain.
- speed up inner yenc decoder loop.
- kentnl said that this module should no longer claim to be a simple
interface to uulib, as the bunndled copy is now better maintained
than the original upstream library.
1.71 Tue Mar 17 00:54:06 CET 2020
- backport to c89 (patch by Paul Howarth).
1.7 Sat Feb 29 22:07:54 CET 2020
- new function: GetFileList.
- experimental perlmulticore support (see manpage).
- Initialize is now a NOP and CleanUp automatically initializes again.
- updated example decoder and documentation a bit.
- include ecb.h to deal with compiler builtins and endianness.
- some further µ-optimisations in hot code, especially for yEnc.
- replace crc32 function by slice-by-16 version by Stephan Brumme,
which should speed up yEnc en-/decoding.
- yEnc: do not calculate two crcs per part, instead, combine
the part crcs together to form the file crc.
- yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
some draft mentions both and it is actually in active use.
- yEnc: ignore crc32= on multiparts, except on the last part,
which avoids spurious corruption warnings.
- be more precise in documenting code licenses in COPYING.
- convert constant creation to the method I normally use.
- use common::sense.
1.62 Mon Feb 17 23:19:42 CET 2020
- major performance improvement by simplifying code in _FP_gets
to not use fscanf. This might slow things down on platforms
with very slow fgetc.
1.61 Sun Feb 9 18:38:29 CET 2020
- lint uulib: fix some format string type mismatches
and some other minor issues.
1.6 Thu Oct 24 17:11:54 CEST 2019
- fix heap overflow (testcase by Noel Duffy, reported
by Robert Scheck). The defense-in-depth mechanism based
on mmap should make this unexploitable for other than denial
of service, on systems supporting mmap/mprotect.
1.5 Sat Jul 11 03:56:06 CEST 2015
- fix a heap overflow (testcase by Krzysztof Wojtaś).
- on systems that support it (posix + mmap + map_anonymous),
allocate all dynamic areas via mmap and put four guard
pages around them, to catch similar heap overflows
safely in the future.
- find a safer way to pass in CC/CFLAGS to uulib.
- added stability canary support.
1.4 Sun May 29 17:17:01 CEST 2011
- avoid a classical buffer overflow in case a progress
message is too long.
- this release adds dependencies for snprintf/vsnprintf.
- some uuencode encoders do not generate a final "space" line
before the "end" marker, so do not rely on the line to be there.
1.34 Tue Dec 14 22:20:00 CET 2010
- fix a one-byte-past-end-write buffer overflow in UURepairData
(reported, analysed and testcase provided by Marco Walther).
- quoted-printable decoding was completely broken, try a fix.
1.33 Wed Oct 28 09:04:38 CET 2009
- handle yEnc files with part end=0 and total= more gracefully.
I wish yEnc had been created by somebody who knows;
what he does;
but I doubt he even knows;
what he did.
1.32 Wed Sep 16 20:07:13 CEST 2009
- Due to a glitch with CVS, configure lacked executable bits.
(Quickly reported by Anton Berezin).
1.31 Wed Sep 16 09:04:30 CEST 2009
- do not use system-replacements for case-insensitive string
functions when found, as they are broken on too many systems
(mostly bsds, as usual, but at least some versions of GNU/Linux
disagree with themselves apparently). Analyzed by Anton Berezin.
1.3 Sat Aug 29 01:24:35 CEST 2009
- major changes, new bugs and changes in decoding behaviour are
expected (but not intended).
- major scanning and decoding speed-up (by a factor of 4),
by replacing ultra-slow _FP_gets and improving IsKnownHeader
(but fgets is *still* responsible for >50% if the time).
- new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
call after every loadfile, majorly speeds up large decodes
(easily by a factor of 10..100).
- allow "Smerge -1" to call UUCheckGlobalList.
- majorly speed up part insertion (still O(n), but much faster).
- allow for 1023 octet headers instead of the standard
255 octet ones.
- support strcasestr, strcasecmp, strncasecmp for added speed.
1.12 Mon Oct 13 14:11:01 CEST 2008
- use the yencode filesize as additional matching criterium
to avoid false matches.
- made the example decoder more verbose w.r.t. error handling.
- removed potentially confusing decode_temp calls from
example decoder.
1.11 Fri Jun 13 15:32:30 CEST 2008
- don't ask.
1.10 Fri Jun 13 14:22:42 CEST 2008
- fix an infinite-looping problem when scanning in freestyle
mode (testcase provided by Pieter Geens and Reinhard Pfau).
1.09 Fri May 25 19:38:11 CEST 2007
- create something sensible, trust a windows program to fuck
it up: work around literal "(null)" filenames in yenc-encoded
files.
- some minor cleanups.
1.08 Sat Dec 16 23:27:13 CET 2006
- URGENT update, the last release did not
decode files correctly, usually not at all.
- my last patch was, of course, completely bogus.
(sorry. looked simple...).
1.07 Sun Dec 10 17:41:46 CET 2006
- fixed an uninitialised variable based on analysis
and patch by Mark Martinec.
