Revision history for Perl extension JSON::XS

2.2
        - 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 its 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          outdated and is nowadays mostly of historical interest.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

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