Revision history for Perl extension JSON::XS

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          outdated and is nowadays mostly of historical interest.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

129	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
130	root	1.54	- make JSON::XS::true and false special overloaded objects
131			and return those instead of 1 and 0 for those json atoms
132			(JSON::PP compatibility is NOT achieved yet).
133			- add JSON::XS::is_bool predicate to test for those special
134			values.
135	root	1.52	- add a reference to
136			http://jpsykes.com/47/practical-csrf-and-json-security.
137	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
138			Also try to be more compatible with slightly older versions,
139	root	1.54	which are not recommended (because they are buggy).
140	root	1.52
141	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
142	root	1.49	- added informative section on JSON-as-YAML.
143	root	1.51	- get rid of some c99-isms again.
144	root	1.50	- localise dec->cur in decode_str, speeding up
145			string decoding considerably (>15% on my amd64 + gcc).
146			- increased SHORT_STRING_LEN to 16kb: stack space is
147			usually plenty, and this actually saves memory
148	root	1.51	when !shrinking as short strings will fit perfectly.
149	root	1.49
150	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
151	root	1.46	- greatly improved small integer encoding and decoding speed.
152			- implement a number of µ-optimisations.
153	root	1.47	- updated benchmarks.
154	root	1.46
155	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
156	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
157			the required macros.
158	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
159	root	1.42
160	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
161	root	1.47	- character offset reported for trailing garbage was random.
162	root	1.41
163	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
164			- decode did not work with magical scalars (doh!).
165	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
166			of unicode.
167	root	1.39	- flag trailing garbage as error.
168			- new decode_prefix method that returns the number
169			of characters consumed by a decode.
170	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
171			as pointed out by Glenn Linderman.
172			- fixed typoe reported by YAMASHINA Hio.
173	root	1.34
174	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
175			- properly 0-terminate sv's returned by encode to help
176			C libraries that expect that 0 to be there.
177	root	1.31	- partially "port" JSON from C to microsofts fucking broken
178			pseudo-C. They should be burned to the ground for pissing
179			on standards. And I should be stoned for even trying to
180	root	1.32	support this filthy excuse for a c compiler.
181	root	1.6
182	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
183	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
184	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
185			leading to segfaults.
186	root	1.30	- further reduced default nesting depth to 512 due to the test
187			failure by that anonymous "chris" whose e-mail address seems
188			to be impossible to get. Tests on other freebsd systems indicate
189			that this is likely a problem in his/her configuration and not this
190			module.
191			- renamed json => JSON in error messages.
192			- corrected the character offset in some error messages.
193	root	1.28
194	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
195			- do not segfault when from_json/decode gets passed
196			a non-string object (reported by Florian Ragwitz).
197			This has no effect on normal operation.
198
199	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
200			- the long awaited (by me) 1.0 version.
201			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
202			true and false.
203	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
204	root	1.25	- improve testsuite.
205	root	1.26	- halve the default nesting depth limit, to hopefully make it
206	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
207			send me his report, so I cannot ask about the stack limit on fbsd).
208	root	1.24
209	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
210	root	1.21	- fix a memleak when decoding hashes.
211	root	1.20	- export jsonToBj and objToJson as aliases
212			to to_json and from_json, to reduce incompatibilities
213			between JSON/JSON::PC and JSON::XS. (experimental).
214	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
215			- added a security considerations sections.
216	root	1.20
217	root	1.19	0.7 Sun Mar 25 01:46:30 CET 2007
218	root	1.16	- code cleanup.
219			- fix a memory overflow bug when indenting.
220			- pretty-printing now up to 15% faster.
221			- improve decoding speed of strings by
222			up to 50% by specialcasing short strings.
223			- further decoding speedups for strings using
224			lots of \u escapes.
225	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
226	root	1.16
227	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
228	root	1.14	- added the UTF-16 encoding example hinted at in previous
229			versions.
230			- minor documentation fixes.
231	root	1.15	- fix a bug in and optimise canonicalising fastpath
232			(reported by Craig Manley).
233			- remove a subtest that breaks with bleadperl (reported
234			by Andreas König).
235	root	1.14
236	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
237	root	1.12	- documentation updates.
238	root	1.13	- do some casting to hopefully fix Andreas' problem.
239			- nuke bogus json rpc stuff.
240	root	1.12
241	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
242	root	1.5	- remove spurious PApp::Util reference (John McNamara).
243			- adapted lots of tests from other json modules
244			(idea by Chris Carline).
245	root	1.9	- documented mapping from json to perl and vice versa.
246	root	1.11	- improved the documentation by adding more examples.
247	root	1.5	- added short escaping forms, reducing the created
248			json texts a bit.
249			- added shrink flag.
250			- when flag methods are called without enable argument
251			they will by default enable their flag.
252			- considerably improved string encoding speed (at least
253			with gcc 4).
254	root	1.7	- added a test that covers lots of different characters.
255			- clarified some error messages.
256			- error messages now use correct character offset
257			with F_UTF8.
258	root	1.8	- improve the "no bytes" and "no warnings" hacks in
259			case the called functions do... stuff.
260	root	1.9	- croak when encoding to ascii and an out-of-range
261			(non-unicode) codepoint is encountered.
262	root	1.4
263	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
264	root	1.109	- the "could not sleep without debugging release".
265	root	1.3	it should basically work now, with many bugs as
266			no production tests have been run yet.
267			- added more testcases.
268			- the expected shitload of bugfixes.
269			- handle utf8 flag correctly in decode.
270			- fix segfault in decoder.
271			- utf8n_to_uvuni sets retlen to -1, but retlen is an
272			unsigned types (argh).
273			- fix decoding of utf-8 strings.
274			- improved error diagnostics.
275			- fix decoding of 'null'.
276			- fix parsing of empty array/hashes
277			- silence warnings when we prepare the croak message.
278
279	root	1.2	0.1 Thu Mar 22 22:13:43 CET 2007
280			- first release, very untested, basically just to claim
281			the namespace.
282	root	1.1
283			0.01 Thu Mar 22 06:08:12 CET 2007
284			- original version; cloned from Convert-Scalar
