[ViewVC] Annotation of: cvs/Convert-UUlib/Changes

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

        - trust filename from yenc header and do not extract it from the header.
        - remove debug message file cvs id's, which didn't work anymore, replace UUMessage
          by a macro and remove file and line numbers from callers.
        - remove some pre-c99 support.
        - compile whole uulib als single .c file.
        - call abort in some code that should not be reached.

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,
          but might, elsewhere.
        - clean up _FP symbol names to 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.

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

114	root	1.47	- major scanning and decoding speed-up (by a factor of 4),
115	root	1.46	by replacing ultra-slow _FP_gets and improving IsKnownHeader
116			(but fgets is still responsible for >50% if the time).
117	root	1.44	- new option OPT_AUTOCHECK to disable O(n) UUCheckGlobalList
118	root	1.45	call after every loadfile, majorly speeds up large decodes
119			(easily by a factor of 10..100).
120			- allow "Smerge -1" to call UUCheckGlobalList.
121			- majorly speed up part insertion (still O(n), but much faster).
122			- allow for 1023 octet headers instead of the standard
123			255 octet ones.
124			- support strcasestr, strcasecmp, strncasecmp for added speed.
125	root	1.44
126	root	1.43	1.12 Mon Oct 13 14:11:01 CEST 2008
127	root	1.41	- use the yencode filesize as additional matching criterium
128			to avoid false matches.
129	root	1.42	- made the example decoder more verbose w.r.t. error handling.
130	root	1.56	- removed potentially confusing decode_temp calls from
131	root	1.43	example decoder.
132	root	1.41
133	root	1.39	1.11 Fri Jun 13 15:32:30 CEST 2008
134			- don't ask.
135
136	root	1.38	1.10 Fri Jun 13 14:22:42 CEST 2008
137			- fix an infinite-looping problem when scanning in freestyle
138	root	1.40	mode (testcase provided by Pieter Geens and Reinhard Pfau).
139	root	1.38
140	root	1.37	1.09 Fri May 25 19:38:11 CEST 2007
141			- create something sensible, trust a windows program to fuck
142			it up: work around literal "(null)" filenames in yenc-encoded
143			files.
144			- some minor cleanups.
145
146	root	1.33	1.08 Sat Dec 16 23:27:13 CET 2006
147	root	1.34	- URGENT update, the last release did not
148	root	1.33	decode files correctly, usually not at all.
149	root	1.38	- my last patch was, of course, completely bogus.
150	root	1.33	(sorry. looked simple...).
151
152	root	1.32	1.07 Sun Dec 10 17:41:46 CET 2006
153			- fixed an uninitialised variable based on analysis
154	root	1.33	and patch by Mark Martinec.
155	root	1.32
156	root	1.31	1.06 Tue Dec 6 00:56:05 CET 2005
157	root	1.29	- fix a number of int/long format errors in the encoding part and
158			fix some signed/unsigned char problems of unknown relevance,
159			reported by Jonas Smedegaard.
160	root	1.30	- new EXPERIMENTAL options OPT_RBUF and OPT_WBUF to set default
161			stdio buffer size for reading and writing files.
162	root	1.29
163	root	1.28	1.051 Thu Mar 3 18:00:52 CET 2005
164			- change of contact address.
165			- updated perl parts to GPLv2.
166
167	root	1.27	1.05 Fri Feb 25 22:50:27 CET 2005
168			- fix a (likely exploitable) segfault problem, (tracked down
169			and/or reported by Mark Martinec and Robert Lewis).
170
171	root	1.26	1.04 Tue Dec 28 15:08:44 CET 2004
172			- slightly improved subject filename extraction.
173			Also see the filename callback in the example-decoder.
174
175	root	1.25	1.03 Sun Apr 18 22:05:43 CEST 2004
176			- upgrade to uudeview-0.5.20, which supposedly fixes a few buffer
177			overflows. However, judging from the patch these vulnerabilities
178			were not present in the Convert-UUlib version (I might err, though,
179			documentation on the actual exploits is scarce).
180			As every uudeview update usually brings more instability than stability
181			I advise against using this version until it has proven itself
182			to be stable, or 1.02 is proven to contain the same buffer overflows.
183
184	root	1.24	1.02 Sun Apr 18 16:47:26 CEST 2004
185			- renamed crc32 to uulib_crc32, to work around yet another
186			shortcoming in this oh-so-outdated macosx.
187
188	root	1.23	1.01 Sun Feb 1 19:49:51 CET 2004
189	root	1.22	- make it compile with 5.005_03 (reported by Anton Berezin).
190	root	1.23	- very short files might not be detected because the header
191			parsing code might skip them.
192	root	1.22
193	root	1.21	1.0 Thu Nov 6 14:32:08 CET 2003
194	root	1.20	- change bracket policy to give priority to (x/y) over (x),
195			and use the last bracket found otherwise.
196			- part numbers at the end of the subject are now recognized.
197	root	1.21	- updated to uulib-0.5.19. Differences and bugfixes kept.
198	root	1.20
199	root	1.19	0.31 Wed Oct 16 01:22:34 CEST 2002
200			- no internal code changes.
201	root	1.18	- much better documentation, now considered "useful".
202			- removed the procedural interface.
203	root	1.20	- fought the wish to perl-5.8'ify and thus simplify the code :().
204	root	1.19	- stress-tested version 0.3 against 70000 data postings since sunday.
205	root	1.18
206	root	1.15	0.3 Sun Oct 13 15:12:11 CEST 2002
207	root	1.17	- updated to uulib 0.5.18. As expected, some but not all of my bugfixes
208	root	1.20	have went into uulib, so the number of differences decreased a bit
209	root	1.17	again.
210			- I found out that the library is being sold commercially by Frank
211			Pilhofer, disregarding the GPL and ignoring the rights of the people
212			who sent in patches :(
213	root	1.14	- vastly more useful documentation in the .pm file.
214	root	1.16	- much smaller distribution filesize ;)
215	root	1.14
216	root	1.12	0.213 Sat Jul 27 21:16:30 CEST 2002
217			- fixed another buffer overflow, also added a santity check to fgets.
218
219	root	1.10	0.212 Sat Apr 6 03:52:13 CEST 2002
220			- fix yEnc decoding support.
221			- new option OPT_DOTDOT, that makes uulib unescape dot-escaping.
222	root	1.11	- increased linelength to 1195.
223	root	1.10
224	root	1.9	0.211 Fri Apr 5 23:56:46 CEST 2002
225	root	1.13	- sigh. new version of uulib, new braindamaged buffer overflows
226			fixed. Diffs like "line length 256 => 300" should have
227	root	1.9	alerted me...
228
229	root	1.7	0.21 Sun Mar 31 22:06:05 CEST 2002
230			- bumped uulib from 0.5.15 to 0.5.17 (adds some yEnc support, YENC_ENCODED).
231			- source-renamed FP_-symbols to _FP_ again, but still define them
232			to be FP_* in the object file.
233	root	1.8	- new callback: SetFileNameCallback (actually documented ;)
234	root	1.7
235	root	1.6	0.201 Sun Sep 16 03:43:38 CEST 2001
236	root	1.5	- fixed another segfault-bug in uulib, thanks to Lars Hecking who
237			provides all the test files ;)
238	root	1.2
239	root	1.5	0.2 Thu Jun 14 18:42:49 CEST 2001
240			- Frank Pilhofer is NOT dead! He is alive, kicking, and fixing
241	root	1.1	bugs in uulib now! Since his uulib and mine diverged quite
242			a bit I am still in the process of merging his bugfixes
243			into my version. So be aware that this might introduce new
244			instabilities...
245			- merged uulib-0.5.15
246	root	1.3	- optimize decode_file to not copy the file contents when a rename
247			succeeds (TMPDIR same disk as destination).
248	root	1.4	- updated documentation.
249	root	1.1
250			0.111 Fri May 4 22:29:09 CEST 2001
251			- heuristic to decode microsoft-rfc822-headers (microsoft uses
252			'\' as path seperator which is also the rfc822 quote character.
253			of course they could have quoted it, but it's microsoft, so
254			only the devil knows how they try to parse mime (they obviously
255			haven't read the standard AGAIN). in case you wonder, this fixes
256			the "c:my_documentssend.doc" "filename" problem.
257
258			0.11 Sun Jul 16 22:42:57 CEST 2000
259			- fixed a bug in the file callback.
260
261			0.10 Tue May 2 03:31:09 CEST 2000
262			- fixed one very longstanding bug that might have been the cause
263			for the many mysterious segmentation faults. Hopefully.
264			- improved documentation to the point that it slowly becomes useful
265			as a (very quick) reference.
266
267			0.07 Wed Nov 24 18:45:23 CET 1999
268			- removed END { CleanUp } from UUlib.pm, perl is too
269			buggy to rely on this in the face of popen etc..
270
271			0.06 Thu Jul 29 22:48:18 CEST 1999
272			- Thierry Bezecourt had the very reasonable idea to include
273			the example source in the manpage.
274
275			0.05 Mon May 24 11:37:25 CEST 1999
276			- LoadFile returns number of parts loaded.
277
278			0.04 Mon May 10 22:02:31 CEST 1999
279			- fixed a couple of portability problems.
280			- UUEncodeToStream had a wrong definition.

285			- renamed it to Convert::UUlib.
286
287			0.02 Fri May 7 01:26:19 CEST 1999
288			- function names exportable (use :all-tag).
289			- made uulist-related functions methods.
290			- the first fix from cpan-tester. sigh you people save the
291			world, continuously.
292
293			0.01 Thu May 6 14:30:44 1999
294			- original version; created by h2xs 1.19
