Revision history for Perl extension JSON::XS

TODO: maybe detetc and croak on more invalid inputs (e.g. +-inf/nan)
TODO: maybe avoid the reblessing and better support readonly objects.
TODO: http://stevehanov.ca/blog/index.php?id=104 compression

        - remove to_json/from_json.
        - minor improvements to the documentation.

2.34 Thu May 23 11:30:34 CEST 2013
        - work around bugs in perl 5.18 breaking more than 100
          widely used modules, without a fix in sight because
          p5pers don't care about CPAN anymore.
        - when canonicalising, only allocate up to 64 hash key
          pointers on the stack. for larger hashes, use the heap,
          to avoid using too much stackspace.
        - discuss the problem with setlocale (reported by a few victims).

2.33 Wed Aug  1 21:03:52 CEST 2012
        - internal encode/decode XS wrappers did not expect stack
          moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
        - add bencode as to/from option in bin/json_xs.
        - add -e option to json_xs, and none and string in/out formats.

2.32 Thu Aug 11 19:06:38 CEST 2011
        - fix a bug in the initial whitespace accumulation.

2.31 Wed Jul 27 17:53:05 CEST 2011
        - don't accumulate initial whitespace in the incremental buffer
          (this can be useful to allow whitespace-keepalive on a tcp
          connection without triggering the max_size limit).
        - properly croak on some invalid inputs that are not strings
          (e.g. undef) when trying to decode a json text (reported
          and analyzed by Goro Fuji).

2.3   Wed Aug 18 01:26:47 CEST 2010
        - make sure decoder doesn't change the decoding in the incremental
          parser (testcase provided by Hendrik Schumacher).
        - applied patch by DaTa for Data::Dumper support in json_xs.
        - added -t dump support to json_xs, using Data::Dump.
        - added -f eval support to json_xs.

2.29  Wed Mar 17 02:39:12 CET 2010
        - fix a memory leak when callbacks set using filter_json_object
          or filter_json_single_key_object were called (great testcase
          by Eric Wilhelm).

2.28  Thu Mar 11 20:30:46 CET 2010
        - implement our own atof function - perl's can be orders of
          magnitudes slower than even the system one. on the positive
          side, ours seems to be more exact in general than perl's.
          (testcase provided by Tim Meadowcroft).
        - clarify floating point conversion issues a bit.
        - update jpsykes csrf article url.
        - updated benchmark section - JSON::PP became much faster!

2.27  Thu Jan  7 07:35:08 CET 2010
        - support relaxed option inside the incremental parser
          (testcase provided by IKEGAMI via Makamaka).

2.26  Sat Oct 10 03:26:19 CEST 2009
        - big integers could become truncated (based on patch
          by Strobl Anton).
        - output format change: indent now adds a final newline, which is
          more expected and more true to the documentation.

2.25  Sat Aug  8 12:04:41 CEST 2009
        - the perl debugger completely breaks lvalue subs - try to work
          around the issue.
        - ignore RMAGICAL hashes w.r.t. CANONICAL.
        - try to work around a possible char signedness issue on aix.
        - require common sense.

2.24  Sat May 30 08:25:45 CEST 2009
        - the incremental parser did not update its parse offset
          pointer correctly when parsing utf8-strings (nicely
          debugged by Martin Evans).
        - appending a non-utf8-string to the incremental parser
          in utf8 mode failed to upgrade the string.
        - wording of parse error messages has been improved.

2.232 Sun Feb 22 11:12:25 CET 2009
        - use an exponential algorithm to extend strings, to
          help platforms with bad or abysmal==windows memory
          allocater performance, at the expense of some memory
          wastage (use shrink to recover this extra memory).
          (nicely analysed by Dmitry Karasik).

2.2311 Thu Feb 19 02:12:54 CET 2009
        - add a section "JSON and ECMAscript" to explain some
          incompatibilities between the two (problem was noted by
          various people).
        - add t/20_faihu.t.

2.231 Thu Nov 20 04:59:08 CET 2008
        - work around 5.10.0 magic bugs where manipulating magic values
          (such as $1) would permanently damage them as perl would
          ignore the magicalness, by making a full copy of the string,
          reported by Dmitry Karasik.
        - work around spurious warnings under older perl 5.8's.

2.23 Mon Sep 29 05:08:29 CEST 2008
        - fix a compilation problem when perl is not using char * as, well,
          char *.
        - use PL_hexdigit in favour of rolling our own.

2.2222 Sun Jul 20 18:49:00 CEST 2008
        - same game again, broken 5.10 finds yet another assertion
          failure, and the workaround causes additional runtime warnings.
          Work around the next assertion AND the warning. 5.10 seriously
          needs to adjust it's attitude against working code.

2.222 Sat Jul 19 06:15:34 CEST 2008
        - you work around one -DDEBUGGING assertion bug in perl 5.10
          just to hit the next one. work around this one, too.

2.22 Tue Jul 15 13:26:51 CEST 2008
        - allow higher nesting levels in incremental parser.
        - error out earlier in some cases in the incremental parser
          (as suggested by Yuval Kogman).
        - improve incr-parser test (Yuval Kogman).

2.21 Tue Jun  3 08:43:23 CEST 2008
        - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
        - remove the experimental status of the incremental parser interface.
        - move =encoding around again, to avoid bugs with search.cpan.org.
          when can we finally have utf-8 in pod???
        - add ->incr_reset method.

2.2  Wed Apr 16 20:37:25 CEST 2008
        - lifted the log2 rounding restriction of max_depth and max_size.
        - make booleans mutable by creating a copy instead of handing out
          the same scalar (reported by pasha sadri).
        - added support for incremental json parsing (still EXPERIMENTAL).
        - implemented and added a json_xs command line utility that can convert
          from/to a number of serialisation formats - tell me if you need more.
        - implement allow_unknown/get_allow_unknown methods.
        - fixed documentation of max_depth w.r.t. higher and equal.
        - moved down =encoding directive a bit, too much breaks if it's the first
          pod directive :/.
        - removed documentation section on other modules, it became somewhat
          outdated and is nowadays mostly of historical interest.

2.1  Wed Mar 19 23:23:18 CET 2008
        - update documentation here and there: add a large section
          about utf8/latin1/ascii flags, add a security consideration
          and extend and clarify the JSON and YAML section.
        - medium speed enhancements when encoding/decoding non-ascii chars.
        - minor speedup in number encoding case.
        - extend and clarify the section on incompatibilities
          between YAML and JSON.
        - switch to static inline from just inline when using gcc.
        - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
        - fix some issues with UV to JSON conversion of unknown impact.
        - published the yahoo locals search result used in benchmarks as the
          original url changes so comparison is impossible.

2.01 Wed Dec  5 11:40:28 CET 2007
        - INCOMPATIBLE API CHANGE: to_json and from_json have been
          renamed to encode_json/decode_json for JSON.pm compatibility.
          The old functions croak and might be replaced by JSON.pm
          comaptible versions in some later release.

2.0  Tue Dec  4 11:30:46 CET 2007
        - this is supposed to be the first version of JSON::XS
          compatible with version 2.0+ of the JSON module.
          Using the JSON module as frontend to JSON::XS should be
          as fast as using JSON::XS directly, so consider using it
          instead.
        - added get_* methods for all "simple" options.
        - make JSON::XS subclassable.

1.53 Tue Nov 13 23:58:33 CET 2007
        - minor doc clarifications.
        - fixed many doc typos (patch by Thomas L. Shinnick).

1.52 Mon Oct 15 03:22:06 CEST 2007
        - remove =encoding pod directive again, it confuses too many pod
          parsers :/.

1.51 Sat Oct 13 03:55:56 CEST 2007
        - encode empty arrays/hashes in a compact way when pretty is enabled.
        - apparently JSON::XS was used to find some bugs in the
          JSON_checker testsuite, so add (the corrected) JSON_checker tests to
          the testsuite.
        - quite a bit of doc updates/extension.
        - require 5.8.2, as this seems to be the first unicode-stable version.

1.5  Tue Aug 28 04:05:38 CEST 2007
        - add support for tied hashes, based on ideas and testcase by
          Marcus Holland-Moritz.
        - implemented relaxed parsing mode where some extensions are being
          accepted. generation is still JSON-only.

1.44 Wed Aug 22 01:02:44 CEST 2007
        - very experimental process-emulation support, slowing everything down.
          the horribly broken perl threads are still not supported - YMMV.

1.43 Thu Jul 26 13:26:37 CEST 2007
        - convert big json numbers exclusively consisting of digits to NV
          only when there is no loss of precision, otherwise to string.

1.42 Tue Jul 24 00:51:18 CEST 2007
        - fix a crash caused by not handling missing array elements
          (report and testcase by Jay Kuri).

1.41 Tue Jul 10 18:21:44 CEST 2007
        - fix compilation with NDEBUG (assert side-effect),
          affects convert_blessed only.
        - fix a bug in decode filters calling ENTER; SAVETMPS;
          one time too often.
        - catch a typical error in TO_JSON methods.
        - antique-ised XS.xs again to work with outdated
          C compilers (windows...).

1.4  Mon Jul  2 10:06:30 CEST 2007
        - add convert_blessed setting.
        - encode did not catch all blessed objects, encoding their
          contents in most cases. This has been fixed by introducing
          the allow_blessed setting.
        - added filter_json_object and filter_json_single_key_object
          settings that specify a callback to be called when
          all/specific json objects are encountered.
        - assume that most object keys are simple ascii words and
          optimise this case, penalising the general case. This can
          speed up decoding by 30% in typical cases and gives
          a smaller and faster perl hash.
        - implemented simpleminded, optional resource size checking
          in decode_json.
        - remove objToJson/jsonToObj aliases, as the next version
          of JSON will not have them either.
        - bit the bullet and converted the very simple json object
          into a more complex one.
        - work around a bug where perl wrongly claims an integer
          is not an integer.
        - unbundle JSON::XS::Boolean into own pm file so Storable
          and similar modules can resolve the overloading when thawing.

1.3  Sun Jun 24 01:55:02 CEST 2007
        - make JSON::XS::true and false special overloaded objects
          and return those instead of 1 and 0 for those json atoms
          (JSON::PP compatibility is NOT achieved yet).
        - add JSON::XS::is_bool predicate to test for those special
          values.
        - add a reference to
          http://jpsykes.com/47/practical-csrf-and-json-security.
        - removed require 5.8.8 again, it is just not very expert-friendly.
          Also try to be more compatible with slightly older versions,
          which are not recommended (because they are buggy).

1.24 Mon Jun 11 05:40:49 CEST 2007
        - added informative section on JSON-as-YAML.
        - get rid of some c99-isms again.
        - localise dec->cur in decode_str, speeding up
          string decoding considerably (>15% on my amd64 + gcc).
        - increased SHORT_STRING_LEN to 16kb: stack space is
          usually plenty, and this actually saves memory
          when !shrinking as short strings will fit perfectly.

1.23 Wed Jun  6 20:13:06 CEST 2007
        - greatly improved small integer encoding and decoding speed.
        - implement a number of µ-optimisations.
        - updated benchmarks.

1.22 Thu May 24 00:07:25 CEST 2007
        - require 5.8.8 explicitly as older perls do not seem to offer
          the required macros.
        - possibly made it compile on so-called C compilers by microsoft.

1.21 Wed May  9 18:40:32 CEST 2007
        - character offset reported for trailing garbage was random.

1.2  Wed May  9 18:35:01 CEST 2007
        - decode did not work with magical scalars (doh!).
        - added latin1 flag to produce JSON texts in the latin1 subset
          of unicode.
        - flag trailing garbage as error.
        - new decode_prefix method that returns the number
          of characters consumed by a decode.
        - max octets/char in perls UTF-X is actually 13, not 11,
          as pointed out by Glenn Linderman.
        - fixed typoe reported by YAMASHINA Hio.

1.11 Mon Apr  9 07:05:49 CEST 2007
        - properly 0-terminate sv's returned by encode to help
          C libraries that expect that 0 to be there.
        - partially "port" JSON from C to microsofts fucking broken
          pseudo-C. They should be burned to the ground for pissing
          on standards. And I should be stoned for even trying to
          support this filthy excuse for a c compiler.

1.1  Wed Apr  4 01:45:00 CEST 2007
        - clarify documentation (pointed out by Quinn Weaver).
        - decode_utf8 sometimes did not correctly flag errors,
          leading to segfaults.
        - further reduced default nesting depth to 512 due to the test
          failure by that anonymous "chris" whose e-mail address seems
          to be impossible to get. Tests on other freebsd systems indicate
          that this is likely a problem in his/her configuration and not this
          module.
        - renamed json => JSON in error messages.
        - corrected the character offset in some error messages.

1.01 Sat Mar 31 16:15:40 CEST 2007
        - do not segfault when from_json/decode gets passed
          a non-string object (reported by Florian Ragwitz).
          This has no effect on normal operation.

1.0  Thu Mar 29 04:43:34 CEST 2007
        - the long awaited (by me) 1.0 version.
        - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
          true and false.
        - add some more notes to shrink, as suggested by Alex Efros.
        - improve testsuite.
        - halve the default nesting depth limit, to hopefully make it
          work on Freebsd (unfortunately, the cpan tester did not
          send me his report, so I cannot ask about the stack limit on fbsd).

0.8  Mon Mar 26 00:10:48 CEST 2007
        - fix a memleak when decoding hashes.
        - export jsonToBj and objToJson as aliases
          to to_json and from_json, to reduce incompatibilities
          between JSON/JSON::PC and JSON::XS. (experimental).
        - implement a maximum nesting depth for both en- and de-coding.
        - added a security considerations sections.

0.7  Sun Mar 25 01:46:30 CET 2007
        - code cleanup.
        - fix a memory overflow bug when indenting.
        - pretty-printing now up to 15% faster.
        - improve decoding speed of strings by
          up to 50% by specialcasing short strings.
        - further decoding speedups for strings using
          lots of \u escapes.
        - improve utf8 decoding speed for U+80 .. U+7FF.

0.5  Sat Mar 24 20:41:51 CET 2007
        - added the UTF-16 encoding example hinted at in previous
          versions.
        - minor documentation fixes.
        - fix a bug in and optimise canonicalising fastpath
          (reported by Craig Manley).
        - remove a subtest that breaks with bleadperl (reported
          by Andreas König).

0.31 Sat Mar 24 02:14:34 CET 2007
        - documentation updates.
        - do some casting to hopefully fix Andreas' problem.
        - nuke bogus json rpc stuff.

0.3  Fri Mar 23 19:33:21 CET 2007
        - remove spurious PApp::Util reference (John McNamara).
        - adapted lots of tests from other json modules
          (idea by Chris Carline).
        - documented mapping from json to perl and vice versa.
        - improved the documentation by adding more examples.
        - added short escaping forms, reducing the created
          json texts a bit.
        - added shrink flag.
        - when flag methods are called without enable argument
          they will by default enable their flag.
        - considerably improved string encoding speed (at least
          with gcc 4).
        - added a test that covers lots of different characters.
        - clarified some error messages.
        - error messages now use correct character offset
          with F_UTF8.
        - improve the "no bytes" and "no warnings" hacks in
          case the called functions do... stuff.
        - croak when encoding to ascii and an out-of-range
          (non-unicode) codepoint is encountered.

0.2  Fri Mar 23 00:23:34 CET 2007
        - the "could not sleep without debugging release".
          it should basically work now, with many bugs as
          no production tests have been run yet.
        - added more testcases.
        - the expected shitload of bugfixes.
        - handle utf8 flag correctly in decode.
        - fix segfault in decoder.
        - utf8n_to_uvuni sets retlen to -1, but retlen is an
          unsigned types (argh).
        - fix decoding of utf-8 strings.
        - improved error diagnostics.
        - fix decoding of 'null'.
        - fix parsing of empty array/hashes
        - silence warnings when we prepare the croak message.

0.1   Thu Mar 22 22:13:43 CET 2007
        - first release, very untested, basically just to claim
          the namespace.
 
0.01  Thu Mar 22 06:08:12 CET 2007

109			failure, and the workaround causes additional runtime warnings.

132	root	1.107	- make booleans mutable by creating a copy instead of handing out
133			the same scalar (reported by pasha sadri).
134	root	1.105	- added support for incremental json parsing (still EXPERIMENTAL).
135	root	1.103	- implemented and added a json_xs command line utility that can convert

137	root	1.108	- implement allow_unknown/get_allow_unknown methods.
138	root	1.109	- fixed documentation of max_depth w.r.t. higher and equal.

157	root	1.92
158	root	1.91	2.01 Wed Dec 5 11:40:28 CET 2007
159			- INCOMPATIBLE API CHANGE: to_json and from_json have been

162			comaptible versions in some later release.
163
164	root	1.90	2.0 Tue Dec 4 11:30:46 CET 2007
165			- this is supposed to be the first version of JSON::XS
166			compatible with version 2.0+ of the JSON module.
167			Using the JSON module as frontend to JSON::XS should be
168			as fast as using JSON::XS directly, so consider using it
169			instead.
170	root	1.88	- added get_* methods for all "simple" options.
171	root	1.89	- make JSON::XS subclassable.
172	root	1.88

180
181	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
182	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
183	root	1.87	- apparently JSON::XS was used to find some bugs in the
184	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
185			the testsuite.
186			- quite a bit of doc updates/extension.
187	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
188	root	1.78
189	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
190	root	1.74	- add support for tied hashes, based on ideas and testcase by
191			Marcus Holland-Moritz.
192	root	1.75	- implemented relaxed parsing mode where some extensions are being
193			accepted. generation is still JSON-only.
194	root	1.74
195			1.44 Wed Aug 22 01:02:44 CEST 2007
196	root	1.73	- very experimental process-emulation support, slowing everything down.
197			the horribly broken perl threads are still not supported - YMMV.
198
199	root	1.72	1.43 Thu Jul 26 13:26:37 CEST 2007

202
203	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007

206
207	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
208			- fix compilation with NDEBUG (assert side-effect),
209			affects convert_blessed only.
210	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
211			one time too often.
212	root	1.70	- catch a typical error in TO_JSON methods.
213	root	1.69	- antique-ised XS.xs again to work with outdated
214			C compilers (windows...).
215
216	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
217	root	1.63	- add convert_blessed setting.
218	root	1.56	- encode did not catch all blessed objects, encoding their
219			contents in most cases. This has been fixed by introducing
220			the allow_blessed setting.
221	root	1.65	- added filter_json_object and filter_json_single_key_object
222			settings that specify a callback to be called when
223	root	1.67	all/specific json objects are encountered.
224	root	1.59	- assume that most object keys are simple ascii words and
225			optimise this case, penalising the general case. This can
226			speed up decoding by 30% in typical cases and gives
227			a smaller and faster perl hash.
228	root	1.58	- implemented simpleminded, optional resource size checking
229			in decode_json.
230	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
231			of JSON will not have them either.
232	root	1.62	- bit the bullet and converted the very simple json object
233			into a more complex one.
234	root	1.64	- work around a bug where perl wrongly claims an integer
235			is not an integer.
236	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
237			and similar modules can resolve the overloading when thawing.
238	root	1.56
239	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
240	root	1.54	- make JSON::XS::true and false special overloaded objects
241			and return those instead of 1 and 0 for those json atoms
242			(JSON::PP compatibility is NOT achieved yet).
243			- add JSON::XS::is_bool predicate to test for those special
244			values.
245	root	1.52	- add a reference to
246			http://jpsykes.com/47/practical-csrf-and-json-security.
247	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
248			Also try to be more compatible with slightly older versions,
249	root	1.54	which are not recommended (because they are buggy).
250	root	1.52
251	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
252	root	1.49	- added informative section on JSON-as-YAML.
253	root	1.51	- get rid of some c99-isms again.
254	root	1.50	- localise dec->cur in decode_str, speeding up
255			string decoding considerably (>15% on my amd64 + gcc).
256			- increased SHORT_STRING_LEN to 16kb: stack space is
257			usually plenty, and this actually saves memory
258	root	1.51	when !shrinking as short strings will fit perfectly.
259	root	1.49
260	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
261	root	1.46	- greatly improved small integer encoding and decoding speed.

264	root	1.46
265	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
266	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
267			the required macros.
268	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
269	root	1.42
270	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
271	root	1.47	- character offset reported for trailing garbage was random.
272	root	1.41
273	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007

275	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
276			of unicode.
277	root	1.39	- flag trailing garbage as error.
278			- new decode_prefix method that returns the number
279			of characters consumed by a decode.
280	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
281			as pointed out by Glenn Linderman.
282			- fixed typoe reported by YAMASHINA Hio.
283	root	1.34
284	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
285			- properly 0-terminate sv's returned by encode to help
286			C libraries that expect that 0 to be there.
287	root	1.31	- partially "port" JSON from C to microsofts fucking broken
288			pseudo-C. They should be burned to the ground for pissing
289			on standards. And I should be stoned for even trying to
290	root	1.32	support this filthy excuse for a c compiler.
291	root	1.6
292	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
293	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
294	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
295			leading to segfaults.
296	root	1.30	- further reduced default nesting depth to 512 due to the test
297			failure by that anonymous "chris" whose e-mail address seems
298			to be impossible to get. Tests on other freebsd systems indicate
299			that this is likely a problem in his/her configuration and not this
300			module.
301			- renamed json => JSON in error messages.
302			- corrected the character offset in some error messages.
303	root	1.28
304	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
305			- do not segfault when from_json/decode gets passed
306			a non-string object (reported by Florian Ragwitz).
307			This has no effect on normal operation.
308
309	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
310			- the long awaited (by me) 1.0 version.
311			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
312			true and false.
313	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
314	root	1.25	- improve testsuite.
315	root	1.26	- halve the default nesting depth limit, to hopefully make it
316	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
317			send me his report, so I cannot ask about the stack limit on fbsd).
318	root	1.24
319	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
320	root	1.21	- fix a memleak when decoding hashes.

341	root	1.15	- fix a bug in and optimise canonicalising fastpath
342			(reported by Craig Manley).

356	root	1.11	- improved the documentation by adding more examples.
357	root	1.5	- added short escaping forms, reducing the created
358			json texts a bit.
359			- added shrink flag.
360			- when flag methods are called without enable argument
361			they will by default enable their flag.
362			- considerably improved string encoding speed (at least
363			with gcc 4).
364	root	1.7	- added a test that covers lots of different characters.
365			- clarified some error messages.
366			- error messages now use correct character offset
367			with F_UTF8.

370	root	1.9	- croak when encoding to ascii and an out-of-range
371			(non-unicode) codepoint is encountered.
372	root	1.4
373	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
374	root	1.109	- the "could not sleep without debugging release".
375	root	1.3	it should basically work now, with many bugs as

379			- handle utf8 flag correctly in decode.
380			- fix segfault in decoder.
