1	Revision history for Perl extension Convert::UUlib.	1	Revision history for Perl extension Convert::UUlib.
		2
		3	TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search
		4
		5	- trust filename from yenc header more.
		6	- remove debug message file cvs id's, which didn't work anymore.
		7
		8	1.8 Thu Dec 17 02:23:53 CET 2020
		9	- no bugfixes in this release due to lack of known bugs, but the major changes
		10	in this release might have introduced new bugs, so watch out.
		11	- update large decoder example to disable OPT_AUTOCHK and use Smerge -1.
		12	- some micro-optimisations.
		13	- avoid costly string comparisons by comparing hashes when isnerting items,
		14	which speeds up insertion by a constant factor.
		15	- improve uulist (and other) structure layout and size.
		16	- reverse the order of file list items, which heuristically improves
		17	match speed with large usenet file lists.
		18	- use getc instead of fgetc, which makes no difference on gnu/linux,
		19	but might, elsewhere.
		20	- clean up _FP symbol names to not start with an underscore.
		21	- use feof_unlocked and ferror_unlocked.
		22	- implement a faster ascii-only strnicmp.
		23	- misc very minor code improvements.
		24	- remove quite a bit of pre-posix/dos/etc. cruft.
		25	- use flockfile, if available, for a potential but small
		26	speed gain.
		27	- speed up inner yenc decoder loop.
		28	- kentnl said that this module should no longer claim to be a simple
		29	interface to uulib, as the bunndled copy is now better maintained
		30	than the original upstream library.
		31
		32	1.71 Tue Mar 17 00:54:06 CET 2020
		33	- backport to c89 (patch by Paul Howarth).
		34
		35	1.7 Sat Feb 29 22:07:54 CET 2020
		36	- new function: GetFileList.
		37	- experimental perlmulticore support (see manpage).
		38	- Initialize is now a NOP and CleanUp automatically initializes again.
		39	- updated example decoder and documentation a bit.
		40	- include ecb.h to deal with compiler builtins and endianness.
		41	- some further µ-optimisations in hot code, especially for yEnc.
		42	- replace crc32 function by slice-by-16 version by Stephan Brumme,
		43	which should speed up yEnc en-/decoding.
		44	- yEnc: do not calculate two crcs per part, instead, combine
		45	the part crcs together to form the file crc.
		46	- yEnc: allow pcrc= in addition to pcrc32= for yenc trailers, as
		47	some draft mentions both and it is actually in active use.
		48	- yEnc: ignore crc32= on multiparts, except on the last part,
		49	which avoids spurious corruption warnings.
		50	- be more precise in documenting code licenses in COPYING.
		51	- convert constant creation to the method I normally use.
		52	- use common::sense.
		53
		54	1.62 Mon Feb 17 23:19:42 CET 2020
		55	- major performance improvement by simplifying code in _FP_gets
		56	to not use fscanf. This might slow things down on platforms
		57	with very slow fgetc.
		58
		59	1.61 Sun Feb 9 18:38:29 CET 2020
		60	- lint uulib: fix some format string type mismatches
		61	and some other minor issues.
		62
		63	1.6 Thu Oct 24 17:11:54 CEST 2019
		64	- fix heap overflow (testcase by Noel Duffy, reported
		65	by Robert Scheck). The defense-in-depth mechanism based
		66	on mmap should make this unexploitable for other than denial
		67	of service, on systems supporting mmap/mprotect.
		68
		69	1.5 Sat Jul 11 03:56:06 CEST 2015
		70	- fix a heap overflow (testcase by Krzysztof Wojtaś).
		71	- on systems that support it (posix + mmap + map_anonymous),
		72	allocate all dynamic areas via mmap and put four guard
		73	pages around them, to catch similar heap overflows
		74	safely in the future.
		75	- find a safer way to pass in CC/CFLAGS to uulib.
		76	- added stability canary support.
		77
		78	1.4 Sun May 29 17:17:01 CEST 2011
		79	- avoid a classical buffer overflow in case a progress
		80	message is too long.
		81	- this release adds dependencies for snprintf/vsnprintf.
		82	- some uuencode encoders do not generate a final "space" line
		83	before the "end" marker, so do not rely on the line to be there.
		84
		85	1.34 Tue Dec 14 22:20:00 CET 2010
		86	- fix a one-byte-past-end-write buffer overflow in UURepairData
		87	(reported, analysed and testcase provided by Marco Walther).
		88	- quoted-printable decoding was completely broken, try a fix.
		89
		90	1.33 Wed Oct 28 09:04:38 CET 2009
		91	- handle yEnc files with part end=0 and total= more gracefully.
		92	I wish yEnc had been created by somebody who knows;
		93	what he does;
		94	but I doubt he even knows;
		95	what he did.
		96
		97	1.32 Wed Sep 16 20:07:13 CEST 2009
		98	- Due to a glitch with CVS, configure lacked executable bits.
		99	(Quickly reported by Anton Berezin).
		100
		101	1.31 Wed Sep 16 09:04:30 CEST 2009
		102	- do not use system-replacements for case-insensitive string
		103	functions when found, as they are broken on too many systems
		104	(mostly bsds, as usual, but at least some versions of GNU/Linux
		105	disagree with themselves apparently). Analyzed by Anton Berezin.
		106
		107	1.3 Sat Aug 29 01:24:35 CEST 2009
		108	- major changes, new bugs and changes in decoding behaviour are
		109	expected (but not intended).
		110	- major scanning and decoding speed-up (by a factor of 4),
		111	by replacing ultra-slow _FP_gets and improving IsKnownHeader
		112	(but fgets is still responsible for >50% if the time).
		113	- new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
		114	call after every loadfile, majorly speeds up large decodes
		115	(easily by a factor of 10..100).
		116	- allow "Smerge -1" to call UUCheckGlobalList.
		117	- majorly speed up part insertion (still O(n), but much faster).
		118	- allow for 1023 octet headers instead of the standard
		119	255 octet ones.
		120	- support strcasestr, strcasecmp, strncasecmp for added speed.
		121
		122	1.12 Mon Oct 13 14:11:01 CEST 2008
		123	- use the yencode filesize as additional matching criterium
		124	to avoid false matches.
		125	- made the example decoder more verbose w.r.t. error handling.
		126	- removed potentially confusing decode_temp calls from
		127	example decoder.
		128
		129	1.11 Fri Jun 13 15:32:30 CEST 2008
		130	- don't ask.
		131
		132	1.10 Fri Jun 13 14:22:42 CEST 2008
		133	- fix an infinite-looping problem when scanning in freestyle
		134	mode (testcase provided by Pieter Geens and Reinhard Pfau).
		135
		136	1.09 Fri May 25 19:38:11 CEST 2007
		137	- create something sensible, trust a windows program to fuck
		138	it up: work around literal "(null)" filenames in yenc-encoded
		139	files.
		140	- some minor cleanups.
		141
		142	1.08 Sat Dec 16 23:27:13 CET 2006
		143	- URGENT update, the last release did not
		144	decode files correctly, usually not at all.
		145	- my last patch was, of course, completely bogus.
		146	(sorry. looked simple...).
		147
		148	1.07 Sun Dec 10 17:41:46 CET 2006
		149	- fixed an uninitialised variable based on analysis
		150	and patch by Mark Martinec.
		151
		152	1.06 Tue Dec 6 00:56:05 CET 2005
		153	- fix a number of int/long format errors in the encoding part and
		154	fix some signed/unsigned char problems of unknown relevance,
		155	reported by Jonas Smedegaard.
		156	- new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
		157	stdio buffer size for reading and writing files.
		158
		159	1.051 Thu Mar 3 18:00:52 CET 2005
		160	- change of contact address.
		161	- updated perl parts to GPLv2.
		162
		163	1.05 Fri Feb 25 22:50:27 CET 2005
		164	- fix a (likely exploitable) segfault problem, (tracked down
		165	and/or reported by Mark Martinec and Robert Lewis).
		166
		167	1.04 Tue Dec 28 15:08:44 CET 2004
		168	- slightly improved subject filename extraction.
		169	Also see the filename callback in the example-decoder.
		170
		171	1.03 Sun Apr 18 22:05:43 CEST 2004
		172	- upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
		173	overflows. However, judging from the patch these vulnerabilities
		174	were not present in the Convert-UUlib version (I might err, though,
		175	documentation on the actual exploits is scarce).
		176	As every uudeview update usually brings more instability than stability
		177	I advise against using this version until it has proven itself
		178	to be stable, or 1.02 is proven to contain the same buffer overflows.
		179
		180	1.02 Sun Apr 18 16:47:26 CEST 2004
		181	- renamed crc32 to uulib_crc32, to work around yet another
		182	shortcoming in this oh-so-outdated macosx.

3	1.01 Sun Feb 1 19:49:51 CET 2004	184	1.01 Sun Feb 1 19:49:51 CET 2004
4	- make it compile with 5.005_03 (reported by Anton Berezin).	185	- make it compile with 5.005_03 (reported by Anton Berezin).
