3TODO: blessed object tests + maxsize 3 - implement our own atof function - perl's can be orders of
41.4 4 magnitudes slower than even the system one. on the positive
5 side, ours seems to be more exact in general than perl's.
6 (testcase provided by Tim Meadowcroft).
7 - update jpsykes csrf article url.
8
92.27 Thu Jan 7 07:35:08 CET 2010
10 - support relaxed option inside the incremental parser
11 (testcase provided by IKEGAMI via Makamaka).
12
132.26 Sat Oct 10 03:26:19 CEST 2009
14 - big integers could become truncated (based on patch
15 by Strobl Anton).
16 - output format change: indent now adds a final newline, which is
17 more expected and more true to the documentation.
18
192.25 Sat Aug 8 12:04:41 CEST 2009
20 - the perl debugger completely breaks lvalue subs - try to work
21 around the issue.
22 - ignore RMAGICAL hashes w.r.t. CANONICAL.
23 - try to work around a possible char signedness issue on aix.
24 - require common sense.
25
262.24 Sat May 30 08:25:45 CEST 2009
27 - the incremental parser did not update its parse offset
28 pointer correctly when parsing utf8-strings (nicely
29 debugged by Martin Evans).
30 - appending a non-utf8-string to the incremental parser
31 in utf8 mode failed to upgrade the string.
32 - wording of parse error messages has been improved.
33
342.232 Sun Feb 22 11:12:25 CET 2009
35 - use an exponential algorithm to extend strings, to
36 help platforms with bad or abysmal==windows memory
37 allocater performance, at the expense of some memory
38 wastage (use shrink to recover this extra memory).
39 (nicely analysed by Dmitry Karasik).
40
412.2311 Thu Feb 19 02:12:54 CET 2009
42 - add a section "JSON and ECMAscript" to explain some
43 incompatibilities between the two (problem was noted by
44 various people).
45 - add t/20_faihu.t.
46
472.231 Thu Nov 20 04:59:08 CET 2008
48 - work around 5.10.0 magic bugs where manipulating magic values
49 (such as $1) would permanently damage them as perl would
50 ignore the magicalness, by making a full copy of the string,
51 reported by Dmitry Karasik.
52 - work around spurious warnings under older perl 5.8's.
53
542.23 Mon Sep 29 05:08:29 CEST 2008
55 - fix a compilation problem when perl is not using char * as, well,
56 char *.
57 - use PL_hexdigit in favour of rolling our own.
58
592.2222 Sun Jul 20 18:49:00 CEST 2008
60 - same game again, broken 5.10 finds yet another assertion
61 failure, and the workaround causes additional runtime warnings.
62 Work around the next assertion AND the warning. 5.10 seriously
63 needs to adjust it's attitude against working code.
64
652.222 Sat Jul 19 06:15:34 CEST 2008
66 - you work around one -DDEBUGGING assertion bug in perl 5.10
67 just to hit the next one. work around this one, too.
68
692.22 Tue Jul 15 13:26:51 CEST 2008
70 - allow higher nesting levels in incremental parser.
71 - error out earlier in some cases in the incremental parser
72 (as suggested by Yuval Kogman).
73 - improve incr-parser test (Yuval Kogman).
74
752.21 Tue Jun 3 08:43:23 CEST 2008
76 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
77 - remove the experimental status of the incremental parser interface.
78 - move =encoding around again, to avoid bugs with search.cpan.org.
79 when can we finally have utf-8 in pod???
80 - add ->incr_reset method.
81
822.2 Wed Apr 16 20:37:25 CEST 2008
83 - lifted the log2 rounding restriction of max_depth and max_size.
84 - make booleans mutable by creating a copy instead of handing out
85 the same scalar (reported by pasha sadri).
86 - added support for incremental json parsing (still EXPERIMENTAL).
87 - implemented and added a json_xs command line utility that can convert
88 from/to a number of serialisation formats - tell me if you need more.
89 - implement allow_unknown/get_allow_unknown methods.
90 - fixed documentation of max_depth w.r.t. higher and equal.
91 - moved down =encoding directive a bit, too much breaks if it's the first
92 pod directive :/.
93 - removed documentation section on other modules, it became somewhat
94 outdated and is nowadays mostly of historical interest.
95
962.1 Wed Mar 19 23:23:18 CET 2008
97 - update documentation here and there: add a large section
98 about utf8/latin1/ascii flags, add a security consideration
99 and extend and clarify the JSON and YAML section.
100 - medium speed enhancements when encoding/decoding non-ascii chars.
101 - minor speedup in number encoding case.
102 - extend and clarify the section on incompatibilities
103 between YAML and JSON.
104 - switch to static inline from just inline when using gcc.
105 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
106 - fix some issues with UV to JSON conversion of unknown impact.
107 - published the yahoo locals search result used in benchmarks as the
108 original url changes so comparison is impossible.
109
1102.01 Wed Dec 5 11:40:28 CET 2007
111 - INCOMPATIBLE API CHANGE: to_json and from_json have been
112 renamed to encode_json/decode_json for JSON.pm compatibility.
113 The old functions croak and might be replaced by JSON.pm
114 comaptible versions in some later release.
115
1162.0 Tue Dec 4 11:30:46 CET 2007
117 - this is supposed to be the first version of JSON::XS
118 compatible with version 2.0+ of the JSON module.
119 Using the JSON module as frontend to JSON::XS should be
120 as fast as using JSON::XS directly, so consider using it
121 instead.
122 - added get_* methods for all "simple" options.
123 - make JSON::XS subclassable.
124
1251.53 Tue Nov 13 23:58:33 CET 2007
126 - minor doc clarifications.
127 - fixed many doc typos (patch by Thomas L. Shinnick).
128
1291.52 Mon Oct 15 03:22:06 CEST 2007
130 - remove =encoding pod directive again, it confuses too many pod
131 parsers :/.
132
1331.51 Sat Oct 13 03:55:56 CEST 2007
134 - encode empty arrays/hashes in a compact way when pretty is enabled.
135 - apparently JSON::XS was used to find some bugs in the
136 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
137 the testsuite.
138 - quite a bit of doc updates/extension.
139 - require 5.8.2, as this seems to be the first unicode-stable version.
140
1411.5 Tue Aug 28 04:05:38 CEST 2007
142 - add support for tied hashes, based on ideas and testcase by
143 Marcus Holland-Moritz.
144 - implemented relaxed parsing mode where some extensions are being
145 accepted. generation is still JSON-only.
146
1471.44 Wed Aug 22 01:02:44 CEST 2007
148 - very experimental process-emulation support, slowing everything down.
149 the horribly broken perl threads are still not supported - YMMV.
150
1511.43 Thu Jul 26 13:26:37 CEST 2007
152 - convert big json numbers exclusively consisting of digits to NV
153 only when there is no loss of precision, otherwise to string.
154
1551.42 Tue Jul 24 00:51:18 CEST 2007
156 - fix a crash caused by not handling missing array elements
157 (report and testcase by Jay Kuri).
158
1591.41 Tue Jul 10 18:21:44 CEST 2007
160 - fix compilation with NDEBUG (assert side-effect),
161 affects convert_blessed only.
162 - fix a bug in decode filters calling ENTER; SAVETMPS;
163 one time too often.
164 - catch a typical error in TO_JSON methods.
165 - antique-ised XS.xs again to work with outdated
166 C compilers (windows...).
167
1681.4 Mon Jul 2 10:06:30 CEST 2007
5 - add convert_blessed option. 169 - add convert_blessed setting.
6 - encode did not catch all blessed objects, encoding their 170 - encode did not catch all blessed objects, encoding their
7 contents in most cases. This has been fixed by introducing 171 contents in most cases. This has been fixed by introducing
8 the allow_blessed setting. 172 the allow_blessed setting.
173 - added filter_json_object and filter_json_single_key_object
174 settings that specify a callback to be called when
175 all/specific json objects are encountered.
9 - assume that most object keys are simple ascii words and 176 - assume that most object keys are simple ascii words and
10 optimise this case, penalising the general case. This can 177 optimise this case, penalising the general case. This can
11 speed up decoding by 30% in typical cases and gives 178 speed up decoding by 30% in typical cases and gives
12 a smaller and faster perl hash. 179 a smaller and faster perl hash.
13 - implemented simpleminded, optional resource size checking 180 - implemented simpleminded, optional resource size checking
14 in decode_json. 181 in decode_json.
182 - remove objToJson/jsonToObj aliases, as the next version
183 of JSON will not have them either.
184 - bit the bullet and converted the very simple json object
185 into a more complex one.
186 - work around a bug where perl wrongly claims an integer
187 is not an integer.
188 - unbundle JSON::XS::Boolean into own pm file so Storable
189 and similar modules can resolve the overloading when thawing.

161.3 Sun Jun 24 01:55:02 CEST 2007 1911.3 Sun Jun 24 01:55:02 CEST 2007
17 - make JSON::XS::true and false special overloaded objects 192 - make JSON::XS::true and false special overloaded objects
18 and return those instead of 1 and 0 for those json atoms 193 and return those instead of 1 and 0 for those json atoms
19 (JSON::PP compatibility is NOT achieved yet). 194 (JSON::PP compatibility is NOT achieved yet).

151 - the "could not sleep without debuggign release". 326 - the "could not sleep without debugging release".
152 it should basically work now, with many bugs as 327 it should basically work now, with many bugs as
153 no production tests have been run yet. 328 no production tests have been run yet.
154 - added more testcases. 329 - added more testcases.
