Revision history for Perl extension JSON::XS

TODO: maybe detetc and croak on more invalid inputs (e.g. +-inf/nan)

        - 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
        - original version; cloned from Convert-Scalar

61
62	root	1.124	2.2311 Thu Feb 19 02:12:54 CET 2009
63	root	1.123	- add a section "JSON and ECMAscript" to explain some
64			incompatibilities between the two (problem was noted by
65			various people).
66	root	1.122	- add t/20_faihu.t.

69			- work around 5.10.0 magic bugs where manipulating magic values
70			(such as $1) would permanently damage them as perl would
71			ignore the magicalness, by making a full copy of the string,
72			reported by Dmitry Karasik.
73	root	1.125	- work around spurious warnings under older perl 5.8's.
74	root	1.121
75	root	1.120	2.23 Mon Sep 29 05:08:29 CEST 2008
76			- fix a compilation problem when perl is not using char * as, well,
77			char *.
78	root	1.119	- use PL_hexdigit in favour of rolling our own.
79
80	root	1.118	2.2222 Sun Jul 20 18:49:00 CEST 2008
81			- same game again, broken 5.10 finds yet another assertion
82			failure, and the workaround causes additional runtime warnings.
83			Work around the next assertion AND the warning. 5.10 seriously
84			needs to adjust it's attitude against working code.
85
86	root	1.117	2.222 Sat Jul 19 06:15:34 CEST 2008
87			- you work around one -DDEBUGGING assertion bug in perl 5.10
88			just to hit the next one. work around this one, too.
89
90	root	1.116	2.22 Tue Jul 15 13:26:51 CEST 2008
91	root	1.115	- allow higher nesting levels in incremental parser.
92			- error out earlier in some cases in the incremental parser
93			(as suggested by Yuval Kogman).
94			- improve incr-parser test (Yuval Kogman).
95
96	root	1.114	2.21 Tue Jun 3 08:43:23 CEST 2008
97			- (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
98	root	1.112	- remove the experimental status of the incremental parser interface.
99	root	1.111	- move =encoding around again, to avoid bugs with search.cpan.org.
100			when can we finally have utf-8 in pod???
101	root	1.113	- add ->incr_reset method.
102	root	1.111
103	root	1.110	2.2 Wed Apr 16 20:37:25 CEST 2008
104	root	1.109	- lifted the log2 rounding restriction of max_depth and max_size.
105	root	1.107	- make booleans mutable by creating a copy instead of handing out
106			the same scalar (reported by pasha sadri).
107	root	1.105	- added support for incremental json parsing (still EXPERIMENTAL).
108	root	1.103	- implemented and added a json_xs command line utility that can convert
109			from/to a number of serialisation formats - tell me if you need more.
110	root	1.108	- implement allow_unknown/get_allow_unknown methods.
111	root	1.109	- fixed documentation of max_depth w.r.t. higher and equal.
112	root	1.112	- moved down =encoding directive a bit, too much breaks if it's the first
113	root	1.102	pod directive :/.
114	root	1.106	- removed documentation section on other modules, it became somewhat
115			outdated and is nowadays mostly of historical interest.
116	root	1.102
117	root	1.101	2.1 Wed Mar 19 23:23:18 CET 2008
118			- update documentation here and there: add a large section
119			about utf8/latin1/ascii flags, add a security consideration
120			and extend and clarify the JSON and YAML section.
121	root	1.98	- medium speed enhancements when encoding/decoding non-ascii chars.
122	root	1.100	- minor speedup in number encoding case.
123	root	1.92	- extend and clarify the section on incompatibilities
124			between YAML and JSON.
125	root	1.95	- switch to static inline from just inline when using gcc.
126	root	1.94	- add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
127	root	1.100	- fix some issues with UV to JSON conversion of unknown impact.
128	root	1.99	- published the yahoo locals search result used in benchmarks as the
129			original url changes so comparison is impossible.
130	root	1.92
131	root	1.91	2.01 Wed Dec 5 11:40:28 CET 2007
132			- INCOMPATIBLE API CHANGE: to_json and from_json have been
133			renamed to encode_json/decode_json for JSON.pm compatibility.
134			The old functions croak and might be replaced by JSON.pm
135			comaptible versions in some later release.
136
137	root	1.90	2.0 Tue Dec 4 11:30:46 CET 2007
138			- this is supposed to be the first version of JSON::XS
139			compatible with version 2.0+ of the JSON module.
140			Using the JSON module as frontend to JSON::XS should be
141			as fast as using JSON::XS directly, so consider using it
142			instead.
143	root	1.88	- added get_* methods for all "simple" options.
144	root	1.89	- make JSON::XS subclassable.
145	root	1.88
146	root	1.86	1.53 Tue Nov 13 23:58:33 CET 2007
147	root	1.85	- minor doc clarifications.
148			- fixed many doc typos (patch by Thomas L. Shinnick).
149
150	root	1.84	1.52 Mon Oct 15 03:22:06 CEST 2007
151	root	1.83	- remove =encoding pod directive again, it confuses too many pod
152			parsers :/.
153
154	root	1.82	1.51 Sat Oct 13 03:55:56 CEST 2007
155	root	1.81	- encode empty arrays/hashes in a compact way when pretty is enabled.
156	root	1.87	- apparently JSON::XS was used to find some bugs in the
157	root	1.80	JSON_checker testsuite, so add (the corrected) JSON_checker tests to
158			the testsuite.
159			- quite a bit of doc updates/extension.
160	root	1.79	- require 5.8.2, as this seems to be the first unicode-stable version.
161	root	1.78
162	root	1.77	1.5 Tue Aug 28 04:05:38 CEST 2007
163	root	1.74	- add support for tied hashes, based on ideas and testcase by
164			Marcus Holland-Moritz.
165	root	1.75	- implemented relaxed parsing mode where some extensions are being
166			accepted. generation is still JSON-only.
167	root	1.74
168			1.44 Wed Aug 22 01:02:44 CEST 2007
169	root	1.73	- very experimental process-emulation support, slowing everything down.
170			the horribly broken perl threads are still not supported - YMMV.
171
172	root	1.72	1.43 Thu Jul 26 13:26:37 CEST 2007
173			- convert big json numbers exclusively consisting of digits to NV
174			only when there is no loss of precision, otherwise to string.
175
176	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007
177			- fix a crash caused by not handling missing array elements
178			(report and testcase by Jay Kuri).
179
180	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
181			- fix compilation with NDEBUG (assert side-effect),
182			affects convert_blessed only.
183	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
184			one time too often.
185	root	1.70	- catch a typical error in TO_JSON methods.
186	root	1.69	- antique-ised XS.xs again to work with outdated
187			C compilers (windows...).
188
189	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
190	root	1.63	- add convert_blessed setting.
191	root	1.56	- encode did not catch all blessed objects, encoding their
192			contents in most cases. This has been fixed by introducing
193			the allow_blessed setting.
194	root	1.65	- added filter_json_object and filter_json_single_key_object
195			settings that specify a callback to be called when
196	root	1.67	all/specific json objects are encountered.
197	root	1.59	- assume that most object keys are simple ascii words and
198			optimise this case, penalising the general case. This can
199			speed up decoding by 30% in typical cases and gives
200			a smaller and faster perl hash.
201	root	1.58	- implemented simpleminded, optional resource size checking
202			in decode_json.
203	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
204			of JSON will not have them either.
205	root	1.62	- bit the bullet and converted the very simple json object
206			into a more complex one.
207	root	1.64	- work around a bug where perl wrongly claims an integer
208			is not an integer.
209	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
210			and similar modules can resolve the overloading when thawing.
211	root	1.56
212	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
213	root	1.54	- make JSON::XS::true and false special overloaded objects
214			and return those instead of 1 and 0 for those json atoms
215			(JSON::PP compatibility is NOT achieved yet).
216			- add JSON::XS::is_bool predicate to test for those special
217			values.
218	root	1.52	- add a reference to
219			http://jpsykes.com/47/practical-csrf-and-json-security.
220	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
221			Also try to be more compatible with slightly older versions,
222	root	1.54	which are not recommended (because they are buggy).
223	root	1.52
224	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
225	root	1.49	- added informative section on JSON-as-YAML.
226	root	1.51	- get rid of some c99-isms again.
227	root	1.50	- localise dec->cur in decode_str, speeding up
228			string decoding considerably (>15% on my amd64 + gcc).
229			- increased SHORT_STRING_LEN to 16kb: stack space is
230			usually plenty, and this actually saves memory
231	root	1.51	when !shrinking as short strings will fit perfectly.
232	root	1.49
233	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
234	root	1.46	- greatly improved small integer encoding and decoding speed.
235			- implement a number of µ-optimisations.
236	root	1.47	- updated benchmarks.
237	root	1.46
238	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
239	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
240			the required macros.
241	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
242	root	1.42
243	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
244	root	1.47	- character offset reported for trailing garbage was random.
245	root	1.41
246	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
247			- decode did not work with magical scalars (doh!).
248	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
249			of unicode.
250	root	1.39	- flag trailing garbage as error.
251			- new decode_prefix method that returns the number
252			of characters consumed by a decode.
253	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
254			as pointed out by Glenn Linderman.
255			- fixed typoe reported by YAMASHINA Hio.
256	root	1.34
257	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
258			- properly 0-terminate sv's returned by encode to help
259			C libraries that expect that 0 to be there.
260	root	1.31	- partially "port" JSON from C to microsofts fucking broken
261			pseudo-C. They should be burned to the ground for pissing
262			on standards. And I should be stoned for even trying to
263	root	1.32	support this filthy excuse for a c compiler.
264	root	1.6
265	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
266	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
267	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
268			leading to segfaults.
269	root	1.30	- further reduced default nesting depth to 512 due to the test
270			failure by that anonymous "chris" whose e-mail address seems
271			to be impossible to get. Tests on other freebsd systems indicate
272			that this is likely a problem in his/her configuration and not this
273			module.
274			- renamed json => JSON in error messages.
275			- corrected the character offset in some error messages.
276	root	1.28
277	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
278			- do not segfault when from_json/decode gets passed
279			a non-string object (reported by Florian Ragwitz).
280			This has no effect on normal operation.
281
282	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
283			- the long awaited (by me) 1.0 version.
284			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
285			true and false.
286	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
287	root	1.25	- improve testsuite.
288	root	1.26	- halve the default nesting depth limit, to hopefully make it
289	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
290			send me his report, so I cannot ask about the stack limit on fbsd).
291	root	1.24
292	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
293	root	1.21	- fix a memleak when decoding hashes.
294	root	1.20	- export jsonToBj and objToJson as aliases
295			to to_json and from_json, to reduce incompatibilities
296			between JSON/JSON::PC and JSON::XS. (experimental).
297	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
298			- added a security considerations sections.
299	root	1.20
300	root	1.19	0.7 Sun Mar 25 01:46:30 CET 2007
301	root	1.16	- code cleanup.
302			- fix a memory overflow bug when indenting.
303			- pretty-printing now up to 15% faster.
304			- improve decoding speed of strings by
305			up to 50% by specialcasing short strings.
306			- further decoding speedups for strings using
307			lots of \u escapes.
308	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
309	root	1.16
310	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
311	root	1.14	- added the UTF-16 encoding example hinted at in previous
312			versions.
313			- minor documentation fixes.
314	root	1.15	- fix a bug in and optimise canonicalising fastpath
315			(reported by Craig Manley).
316			- remove a subtest that breaks with bleadperl (reported
317			by Andreas König).
318	root	1.14
319	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
320	root	1.12	- documentation updates.
321	root	1.13	- do some casting to hopefully fix Andreas' problem.
322			- nuke bogus json rpc stuff.
323	root	1.12
324	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
325	root	1.5	- remove spurious PApp::Util reference (John McNamara).
326			- adapted lots of tests from other json modules
327			(idea by Chris Carline).
328	root	1.9	- documented mapping from json to perl and vice versa.
329	root	1.11	- improved the documentation by adding more examples.
330	root	1.5	- added short escaping forms, reducing the created
331			json texts a bit.
332			- added shrink flag.
333			- when flag methods are called without enable argument
334			they will by default enable their flag.
335			- considerably improved string encoding speed (at least
336			with gcc 4).
337	root	1.7	- added a test that covers lots of different characters.
338			- clarified some error messages.
339			- error messages now use correct character offset
340			with F_UTF8.
341	root	1.8	- improve the "no bytes" and "no warnings" hacks in
342			case the called functions do... stuff.
343	root	1.9	- croak when encoding to ascii and an out-of-range
344			(non-unicode) codepoint is encountered.
345	root	1.4
346	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
347	root	1.109	- the "could not sleep without debugging release".
348	root	1.3	it should basically work now, with many bugs as
349			no production tests have been run yet.
350			- added more testcases.
351			- the expected shitload of bugfixes.
352			- handle utf8 flag correctly in decode.
353			- fix segfault in decoder.
354			- utf8n_to_uvuni sets retlen to -1, but retlen is an
355			unsigned types (argh).
356			- fix decoding of utf-8 strings.
357			- improved error diagnostics.
358			- fix decoding of 'null'.
359			- fix parsing of empty array/hashes
360			- silence warnings when we prepare the croak message.
361
362	root	1.2	0.1 Thu Mar 22 22:13:43 CET 2007
363			- first release, very untested, basically just to claim
364			the namespace.
365	root	1.1
366			0.01 Thu Mar 22 06:08:12 CET 2007
