Revision history for Perl extension JSON::XS

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 wanrings 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          outdated and is nowadays mostly of historical interest.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

111	root	1.71	1.42 Tue Jul 24 00:51:18 CEST 2007
112			- fix a crash caused by not handling missing array elements
113			(report and testcase by Jay Kuri).
114
115	root	1.70	1.41 Tue Jul 10 18:21:44 CEST 2007
116			- fix compilation with NDEBUG (assert side-effect),
117			affects convert_blessed only.
118	root	1.69	- fix a bug in decode filters calling ENTER; SAVETMPS;
119			one time too often.
120	root	1.70	- catch a typical error in TO_JSON methods.
121	root	1.69	- antique-ised XS.xs again to work with outdated
122			C compilers (windows...).
123
124	root	1.68	1.4 Mon Jul 2 10:06:30 CEST 2007
125	root	1.63	- add convert_blessed setting.
126	root	1.56	- encode did not catch all blessed objects, encoding their
127			contents in most cases. This has been fixed by introducing
128			the allow_blessed setting.
129	root	1.65	- added filter_json_object and filter_json_single_key_object
130			settings that specify a callback to be called when
131	root	1.67	all/specific json objects are encountered.
132	root	1.59	- assume that most object keys are simple ascii words and
133			optimise this case, penalising the general case. This can
134			speed up decoding by 30% in typical cases and gives
135			a smaller and faster perl hash.
136	root	1.58	- implemented simpleminded, optional resource size checking
137			in decode_json.
138	root	1.61	- remove objToJson/jsonToObj aliases, as the next version
139			of JSON will not have them either.
140	root	1.62	- bit the bullet and converted the very simple json object
141			into a more complex one.
142	root	1.64	- work around a bug where perl wrongly claims an integer
143			is not an integer.
144	root	1.65	- unbundle JSON::XS::Boolean into own pm file so Storable
145			and similar modules can resolve the overloading when thawing.
146	root	1.56
147	root	1.55	1.3 Sun Jun 24 01:55:02 CEST 2007
148	root	1.54	- make JSON::XS::true and false special overloaded objects
149			and return those instead of 1 and 0 for those json atoms
150			(JSON::PP compatibility is NOT achieved yet).
151			- add JSON::XS::is_bool predicate to test for those special
152			values.
153	root	1.52	- add a reference to
154			http://jpsykes.com/47/practical-csrf-and-json-security.
155	root	1.60	- removed require 5.8.8 again, it is just not very expert-friendly.
156			Also try to be more compatible with slightly older versions,
157	root	1.54	which are not recommended (because they are buggy).
158	root	1.52
159	root	1.51	1.24 Mon Jun 11 05:40:49 CEST 2007
160	root	1.49	- added informative section on JSON-as-YAML.
161	root	1.51	- get rid of some c99-isms again.
162	root	1.50	- localise dec->cur in decode_str, speeding up
163			string decoding considerably (>15% on my amd64 + gcc).
164			- increased SHORT_STRING_LEN to 16kb: stack space is
165			usually plenty, and this actually saves memory
166	root	1.51	when !shrinking as short strings will fit perfectly.
167	root	1.49
168	root	1.47	1.23 Wed Jun 6 20:13:06 CEST 2007
169	root	1.46	- greatly improved small integer encoding and decoding speed.
170			- implement a number of µ-optimisations.
171	root	1.47	- updated benchmarks.
172	root	1.46
173	root	1.45	1.22 Thu May 24 00:07:25 CEST 2007
174	root	1.42	- require 5.8.8 explicitly as older perls do not seem to offer
175			the required macros.
176	root	1.43	- possibly made it compile on so-called C compilers by microsoft.
177	root	1.42
178	root	1.41	1.21 Wed May 9 18:40:32 CEST 2007
179	root	1.47	- character offset reported for trailing garbage was random.
180	root	1.41
181	root	1.40	1.2 Wed May 9 18:35:01 CEST 2007
182			- decode did not work with magical scalars (doh!).
183	root	1.38	- added latin1 flag to produce JSON texts in the latin1 subset
184			of unicode.
185	root	1.39	- flag trailing garbage as error.
186			- new decode_prefix method that returns the number
187			of characters consumed by a decode.
188	root	1.40	- max octets/char in perls UTF-X is actually 13, not 11,
189			as pointed out by Glenn Linderman.
190			- fixed typoe reported by YAMASHINA Hio.
191	root	1.34
192	root	1.32	1.11 Mon Apr 9 07:05:49 CEST 2007
193			- properly 0-terminate sv's returned by encode to help
194			C libraries that expect that 0 to be there.
195	root	1.31	- partially "port" JSON from C to microsofts fucking broken
196			pseudo-C. They should be burned to the ground for pissing
197			on standards. And I should be stoned for even trying to
198	root	1.32	support this filthy excuse for a c compiler.
199	root	1.6
200	root	1.30	1.1 Wed Apr 4 01:45:00 CEST 2007
201	root	1.28	- clarify documentation (pointed out by Quinn Weaver).
202	root	1.29	- decode_utf8 sometimes did not correctly flag errors,
203			leading to segfaults.
204	root	1.30	- further reduced default nesting depth to 512 due to the test
205			failure by that anonymous "chris" whose e-mail address seems
206			to be impossible to get. Tests on other freebsd systems indicate
207			that this is likely a problem in his/her configuration and not this
208			module.
209			- renamed json => JSON in error messages.
210			- corrected the character offset in some error messages.
211	root	1.28
212	root	1.27	1.01 Sat Mar 31 16:15:40 CEST 2007
213			- do not segfault when from_json/decode gets passed
214			a non-string object (reported by Florian Ragwitz).
215			This has no effect on normal operation.
216
217	root	1.25	1.0 Thu Mar 29 04:43:34 CEST 2007
218			- the long awaited (by me) 1.0 version.
219			- add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
220			true and false.
221	root	1.24	- add some more notes to shrink, as suggested by Alex Efros.
222	root	1.25	- improve testsuite.
223	root	1.26	- halve the default nesting depth limit, to hopefully make it
224	root	1.25	work on Freebsd (unfortunately, the cpan tester did not
225			send me his report, so I cannot ask about the stack limit on fbsd).
226	root	1.24
227	root	1.23	0.8 Mon Mar 26 00:10:48 CEST 2007
228	root	1.21	- fix a memleak when decoding hashes.
229	root	1.20	- export jsonToBj and objToJson as aliases
230			to to_json and from_json, to reduce incompatibilities
231			between JSON/JSON::PC and JSON::XS. (experimental).
232	root	1.21	- implement a maximum nesting depth for both en- and de-coding.
233			- added a security considerations sections.
234	root	1.20
235	root	1.19	0.7 Sun Mar 25 01:46:30 CET 2007
236	root	1.16	- code cleanup.
237			- fix a memory overflow bug when indenting.
238			- pretty-printing now up to 15% faster.
239			- improve decoding speed of strings by
240			up to 50% by specialcasing short strings.
241			- further decoding speedups for strings using
242			lots of \u escapes.
243	root	1.17	- improve utf8 decoding speed for U+80 .. U+7FF.
244	root	1.16
245	root	1.15	0.5 Sat Mar 24 20:41:51 CET 2007
246	root	1.14	- added the UTF-16 encoding example hinted at in previous
247			versions.
248			- minor documentation fixes.
249	root	1.15	- fix a bug in and optimise canonicalising fastpath
250			(reported by Craig Manley).
251			- remove a subtest that breaks with bleadperl (reported
252			by Andreas König).
253	root	1.14
254	root	1.13	0.31 Sat Mar 24 02:14:34 CET 2007
255	root	1.12	- documentation updates.
256	root	1.13	- do some casting to hopefully fix Andreas' problem.
257			- nuke bogus json rpc stuff.
258	root	1.12
259	root	1.11	0.3 Fri Mar 23 19:33:21 CET 2007
260	root	1.5	- remove spurious PApp::Util reference (John McNamara).
261			- adapted lots of tests from other json modules
262			(idea by Chris Carline).
263	root	1.9	- documented mapping from json to perl and vice versa.
264	root	1.11	- improved the documentation by adding more examples.
265	root	1.5	- added short escaping forms, reducing the created
266			json texts a bit.
267			- added shrink flag.
268			- when flag methods are called without enable argument
269			they will by default enable their flag.
270			- considerably improved string encoding speed (at least
271			with gcc 4).
272	root	1.7	- added a test that covers lots of different characters.
273			- clarified some error messages.
274			- error messages now use correct character offset
275			with F_UTF8.
276	root	1.8	- improve the "no bytes" and "no warnings" hacks in
277			case the called functions do... stuff.
278	root	1.9	- croak when encoding to ascii and an out-of-range
279			(non-unicode) codepoint is encountered.
280	root	1.4
281	root	1.3	0.2 Fri Mar 23 00:23:34 CET 2007
282	root	1.109	- the "could not sleep without debugging release".
283	root	1.3	it should basically work now, with many bugs as
284			no production tests have been run yet.
285			- added more testcases.
286			- the expected shitload of bugfixes.
287			- handle utf8 flag correctly in decode.
288			- fix segfault in decoder.
289			- utf8n_to_uvuni sets retlen to -1, but retlen is an
290			unsigned types (argh).
291			- fix decoding of utf-8 strings.
292			- improved error diagnostics.
293			- fix decoding of 'null'.
294			- fix parsing of empty array/hashes
295			- silence warnings when we prepare the croak message.
296
297	root	1.2	0.1 Thu Mar 22 22:13:43 CET 2007
298			- first release, very untested, basically just to claim
299			the namespace.
300	root	1.1
301			0.01 Thu Mar 22 06:08:12 CET 2007
302			- original version; cloned from Convert-Scalar
