Revision history for Perl extension Convert::UUlib.

TODO: biggest timesinks: FP_fgets/getc_unlocked overall, UUInsertPartToList dominates large loads due to O(n**2) search

04:59:03 <kentnl> schmorp: you may want to change the description on Convert-UUlib, because your bundled copy
                  is now better maintained and has fewer security risks than upstreams :p
04:59:49 <kentnl> to the point I've been humoring the idea of cribbing its code and shipping it as a
                  replacement for other things currently using the original uulib
06:51:00 <schmorp> kentnl: well, hmm, but change it to what, it still is an interface to "a" uulib library at
                   least
06:52:26 <kentnl> Maybe "Convert to/from uuencoded data in C" or something like that.

        - update large decoder example to disable OPT_AUTOCHK dn use Smerge -1.
        - relatively minor speed increasses.
        - reverse the order of file list items, which heuristically improves
          match speed with large usenet file lists.
        - use getc instead of fgetc.
        - clean up FP _symbol names.
        - 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 avaiolable, for a potential but small
          speed gain.

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.

1.06 Tue Dec  6 00:56:05 CET 2005
        - fix a number of int/long format errors in the encoding part and
          fix some signed/unsigned char problems of unknown relevance,
          reported by Jonas Smedegaard.
        - new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
          stdio buffer size for reading and writing files.

1.051 Thu Mar  3 18:00:52 CET 2005
        - change of contact address.
        - updated perl parts to GPLv2.

1.05 Fri Feb 25 22:50:27 CET 2005
        - fix a (likely exploitable) segfault problem, (tracked down
          and/or reported by Mark Martinec and Robert Lewis).

1.04 Tue Dec 28 15:08:44 CET 2004
        - slightly improved subject filename extraction.
          Also see the filename callback in the example-decoder.

1.03 Sun Apr 18 22:05:43 CEST 2004
        - upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
          overflows. However, judging from the patch these vulnerabilities
          were not present in the Convert-UUlib version (I might err, though,
          documentation on the actual exploits is scarce).
          As every uudeview update usually brings more instability than stability
          I advise against using this version until it has proven itself
          to be stable, or 1.02 is proven to contain the same buffer overflows.

1.02 Sun Apr 18 16:47:26 CEST 2004
        - renamed crc32 to uulib_crc32, to work around yet another
          shortcoming in this oh-so-outdated macosx.

1.01 Sun Feb  1 19:49:51 CET 2004
        - make it compile with 5.005_03 (reported by Anton Berezin).
        - very short files might not be detected because the header
          parsing code might skip them.

1.0  Thu Nov  6 14:32:08 CET 2003
        - change bracket policy to give priority to (x/y) over (x),
          and use the last bracket found otherwise.
        - part numbers at the end of the subject are now recognized.
        - updated to uulib-0.5.19. Differences and bugfixes kept.

0.31 Wed Oct 16 01:22:34 CEST 2002
        - no internal code changes.
        - much better documentation, now considered "useful".
        - removed the procedural interface.
        - fought the wish to perl-5.8'ify and thus simplify the code :().
        - stress-tested version 0.3 against 70000 data postings since sunday.

0.3   Sun Oct 13 15:12:11 CEST 2002
        - updated to uulib 0.5.18. As expected, some but not all of my bugfixes
          have went into uulib, so the number of differences decreased a bit
          again.
        - I found out that the library is being sold commercially by Frank
          Pilhofer, disregarding the GPL and ignoring the rights of the people
          who sent in patches :(
        - vastly more useful documentation in the .pm file.
        - much smaller distribution filesize ;)

0.213 Sat Jul 27 21:16:30 CEST 2002
        - fixed another buffer overflow, also added a santity check to fgets.

0.212 Sat Apr  6 03:52:13 CEST 2002
        - fix yEnc decoding support.
        - new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
        - increased linelength to 1195.

0.211 Fri Apr  5 23:56:46 CEST 2002
        - *sigh*. new version of uulib, new braindamaged buffer overflows
          fixed. Diffs like "line length 256 => 300" should have
          alerted me...

0.21  Sun Mar 31 22:06:05 CEST 2002
        - bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
        - source-renamed FP_*-symbols to _FP_* again, but still define them
          to be FP_* in the object file.
        - new callback: SetFileNameCallback (actually documented ;)

0.201 Sun Sep 16 03:43:38 CEST 2001
        - fixed another segfault-bug in uulib, thanks to Lars Hecking who
          provides all the test files ;)

0.2  Thu Jun 14 18:42:49 CEST 2001
        - Frank Pilhofer is NOT dead! He is alive, kicking, and fixing
          bugs in uulib now! Since his uulib and mine diverged quite
          a bit I am still in the process of merging his bugfixes
          into my version. So be aware that this might introduce new
          instabilities...
        - merged uulib-0.5.15
        - optimize decode_file to not copy the file contents when a rename
          succeeds (TMPDIR same disk as destination).
        - updated documentation.

0.111 Fri May  4 22:29:09 CEST 2001
        - heuristic to decode microsoft-rfc822-headers (microsoft uses
          '\' as path seperator which is also the rfc822 quote character.
          of course they could have quoted it, but it's microsoft, so
          only the devil knows how they try to parse mime (they obviously
          haven't read the standard AGAIN). in case you wonder, this fixes
          the "c:my_documentssend.doc" "filename" problem.

0.11  Sun Jul 16 22:42:57 CEST 2000
        - fixed a bug in the file callback.

0.10  Tue May  2 03:31:09 CEST 2000
        - fixed one very longstanding bug that might have been the cause
          for the many mysterious segmentation faults. Hopefully.
        - improved documentation to the point that it slowly becomes useful
          as a (very quick) reference.

0.07  Wed Nov 24 18:45:23 CET 1999
        - removed END { CleanUp } from UUlib.pm, perl is too
          buggy to rely on this in the face of popen etc..

0.06  Thu Jul 29 22:48:18 CEST 1999
        - Thierry Bezecourt had the very reasonable idea to include
          the example source in the manpage.

0.05  Mon May 24 11:37:25 CEST 1999
        - LoadFile returns number of parts loaded.

0.04  Mon May 10 22:02:31 CEST 1999
        - fixed a couple of portability problems.
        - UUEncodeToStream had a wrong definition.
        - added primitive testsuite.
        - added README.

0.03  Sat May  8 22:40:01 CEST 1999
        - renamed it to Convert::UUlib.

0.02  Fri May  7 01:26:19 CEST 1999
        - function names exportable (use :all-tag).
        - made uulist-related functions methods.
        - the first fix from cpan-tester. *sigh* you people save the
          world, continuously.

0.01  Thu May  6 14:30:44 1999
        - original version; created by h2xs 1.19

146	1.06 Tue Dec 6 00:56:05 CET 2005
147	- fix a number of int/long format errors in the encoding part and
148	fix some signed/unsigned char problems of unknown relevance,
149	reported by Jonas Smedegaard.
150	- new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
151	stdio buffer size for reading and writing files.
152
153	1.051 Thu Mar 3 18:00:52 CET 2005
154	- change of contact address.
155	- updated perl parts to GPLv2.
156
157	1.05 Fri Feb 25 22:50:27 CET 2005
158	- fix a (likely exploitable) segfault problem, (tracked down
159	and/or reported by Mark Martinec and Robert Lewis).
160
161	1.04 Tue Dec 28 15:08:44 CET 2004
162	- slightly improved subject filename extraction.
163	Also see the filename callback in the example-decoder.
164
165	1.03 Sun Apr 18 22:05:43 CEST 2004
166	- upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
167	overflows. However, judging from the patch these vulnerabilities
168	were not present in the Convert-UUlib version (I might err, though,
169	documentation on the actual exploits is scarce).
170	As every uudeview update usually brings more instability than stability
171	I advise against using this version until it has proven itself
172	to be stable, or 1.02 is proven to contain the same buffer overflows.
173
174	1.02 Sun Apr 18 16:47:26 CEST 2004
175	- renamed crc32 to uulib_crc32, to work around yet another
176	shortcoming in this oh-so-outdated macosx.
177
178	1.01 Sun Feb 1 19:49:51 CET 2004
179	- make it compile with 5.005_03 (reported by Anton Berezin).
180	- very short files might not be detected because the header
181	parsing code might skip them.
182
183	1.0 Thu Nov 6 14:32:08 CET 2003
184	- change bracket policy to give priority to (x/y) over (x),
185	and use the last bracket found otherwise.
186	- part numbers at the end of the subject are now recognized.
187	- updated to uulib-0.5.19. Differences and bugfixes kept.
188
189	0.31 Wed Oct 16 01:22:34 CEST 2002
190	- no internal code changes.
191	- much better documentation, now considered "useful".
192	- removed the procedural interface.
193	- fought the wish to perl-5.8'ify and thus simplify the code :().
194	- stress-tested version 0.3 against 70000 data postings since sunday.
195
196	0.3 Sun Oct 13 15:12:11 CEST 2002
197	- updated to uulib 0.5.18. As expected, some but not all of my bugfixes
198	have went into uulib, so the number of differences decreased a bit
199	again.
200	- I found out that the library is being sold commercially by Frank
201	Pilhofer, disregarding the GPL and ignoring the rights of the people
202	who sent in patches :(
203	- vastly more useful documentation in the .pm file.
204	- much smaller distribution filesize ;)
205
206	0.213 Sat Jul 27 21:16:30 CEST 2002
207	- fixed another buffer overflow, also added a santity check to fgets.
208
209	0.212 Sat Apr 6 03:52:13 CEST 2002
210	- fix yEnc decoding support.
211	- new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
212	- increased linelength to 1195.
213
214	0.211 Fri Apr 5 23:56:46 CEST 2002
215	- sigh. new version of uulib, new braindamaged buffer overflows
216	fixed. Diffs like "line length 256 => 300" should have
217	alerted me...
218
219	0.21 Sun Mar 31 22:06:05 CEST 2002
220	- bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
221	- source-renamed FP_-symbols to _FP_ again, but still define them
222	to be FP_* in the object file.
223	- new callback: SetFileNameCallback (actually documented ;)
224
225	0.201 Sun Sep 16 03:43:38 CEST 2001
226	- fixed another segfault-bug in uulib, thanks to Lars Hecking who
227	provides all the test files ;)
228
229	0.2 Thu Jun 14 18:42:49 CEST 2001
230	- Frank Pilhofer is NOT dead! He is alive, kicking, and fixing
231	bugs in uulib now! Since his uulib and mine diverged quite
232	a bit I am still in the process of merging his bugfixes
233	into my version. So be aware that this might introduce new
234	instabilities...
235	- merged uulib-0.5.15
236	- optimize decode_file to not copy the file contents when a rename
237	succeeds (TMPDIR same disk as destination).
238	- updated documentation.
239
240	0.111 Fri May 4 22:29:09 CEST 2001
241	- heuristic to decode microsoft-rfc822-headers (microsoft uses
242	'\' as path seperator which is also the rfc822 quote character.
243	of course they could have quoted it, but it's microsoft, so
244	only the devil knows how they try to parse mime (they obviously
245	haven't read the standard AGAIN). in case you wonder, this fixes
246	the "c:my_documentssend.doc" "filename" problem.
247
248	0.11 Sun Jul 16 22:42:57 CEST 2000
249	- fixed a bug in the file callback.
250
251	0.10 Tue May 2 03:31:09 CEST 2000
252	- fixed one very longstanding bug that might have been the cause
253	for the many mysterious segmentation faults. Hopefully.
254	- improved documentation to the point that it slowly becomes useful
255	as a (very quick) reference.
256
257	0.07 Wed Nov 24 18:45:23 CET 1999
258	- removed END { CleanUp } from UUlib.pm, perl is too
259	buggy to rely on this in the face of popen etc..
260
261	0.06 Thu Jul 29 22:48:18 CEST 1999
262	- Thierry Bezecourt had the very reasonable idea to include
263	the example source in the manpage.
264
265	0.05 Mon May 24 11:37:25 CEST 1999
266	- LoadFile returns number of parts loaded.
267
268	0.04 Mon May 10 22:02:31 CEST 1999
269	- fixed a couple of portability problems.
270	- UUEncodeToStream had a wrong definition.
271	- added primitive testsuite.
272	- added README.
273
274	0.03 Sat May 8 22:40:01 CEST 1999
275	- renamed it to Convert::UUlib.
276
277	0.02 Fri May 7 01:26:19 CEST 1999
278	- function names exportable (use :all-tag).
279	- made uulist-related functions methods.
280	- the first fix from cpan-tester. sigh you people save the
281	world, continuously.
282
283	0.01 Thu May 6 14:30:44 1999
284	- original version; created by h2xs 1.19
