2 2
31.4 3TODO: -f eval
4 - applied patch by DaTa for Data::Dumper support in json_xs.
5 - added -t dump support to json_xs, using Data::Dump.
6
72.29 Wed Mar 17 02:39:12 CET 2010
8 - fix a memory leak when callbacks set using filter_json_object
9 or filter_json_single_key_object were called (great testcase
10 by Eric Wilhelm).
11
122.28 Thu Mar 11 20:30:46 CET 2010
13 - implement our own atof function - perl's can be orders of
14 magnitudes slower than even the system one. on the positive
15 side, ours seems to be more exact in general than perl's.
16 (testcase provided by Tim Meadowcroft).
17 - clarify floating point conversion issues a bit.
18 - update jpsykes csrf article url.
19 - updated benchmark section - JSON::PP became much faster!
20
212.27 Thu Jan 7 07:35:08 CET 2010
22 - support relaxed option inside the incremental parser
23 (testcase provided by IKEGAMI via Makamaka).
24
252.26 Sat Oct 10 03:26:19 CEST 2009
26 - big integers could become truncated (based on patch
27 by Strobl Anton).
28 - output format change: indent now adds a final newline, which is
29 more expected and more true to the documentation.
30
312.25 Sat Aug 8 12:04:41 CEST 2009
32 - the perl debugger completely breaks lvalue subs - try to work
33 around the issue.
34 - ignore RMAGICAL hashes w.r.t. CANONICAL.
35 - try to work around a possible char signedness issue on aix.
36 - require common sense.
37
382.24 Sat May 30 08:25:45 CEST 2009
39 - the incremental parser did not update its parse offset
40 pointer correctly when parsing utf8-strings (nicely
41 debugged by Martin Evans).
42 - appending a non-utf8-string to the incremental parser
43 in utf8 mode failed to upgrade the string.
44 - wording of parse error messages has been improved.
45
462.232 Sun Feb 22 11:12:25 CET 2009
47 - use an exponential algorithm to extend strings, to
48 help platforms with bad or abysmal==windows memory
49 allocater performance, at the expense of some memory
50 wastage (use shrink to recover this extra memory).
51 (nicely analysed by Dmitry Karasik).
52
532.2311 Thu Feb 19 02:12:54 CET 2009
54 - add a section "JSON and ECMAscript" to explain some
55 incompatibilities between the two (problem was noted by
56 various people).
57 - add t/20_faihu.t.
58
592.231 Thu Nov 20 04:59:08 CET 2008
60 - work around 5.10.0 magic bugs where manipulating magic values
61 (such as $1) would permanently damage them as perl would
62 ignore the magicalness, by making a full copy of the string,
63 reported by Dmitry Karasik.
64 - work around spurious warnings under older perl 5.8's.
65
662.23 Mon Sep 29 05:08:29 CEST 2008
67 - fix a compilation problem when perl is not using char * as, well,
68 char *.
69 - use PL_hexdigit in favour of rolling our own.
70
712.2222 Sun Jul 20 18:49:00 CEST 2008
72 - same game again, broken 5.10 finds yet another assertion
73 failure, and the workaround causes additional runtime warnings.
74 Work around the next assertion AND the warning. 5.10 seriously
75 needs to adjust it's attitude against working code.
76
772.222 Sat Jul 19 06:15:34 CEST 2008
78 - you work around one -DDEBUGGING assertion bug in perl 5.10
79 just to hit the next one. work around this one, too.
80
812.22 Tue Jul 15 13:26:51 CEST 2008
82 - allow higher nesting levels in incremental parser.
83 - error out earlier in some cases in the incremental parser
84 (as suggested by Yuval Kogman).
85 - improve incr-parser test (Yuval Kogman).
86
872.21 Tue Jun 3 08:43:23 CEST 2008
88 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
89 - remove the experimental status of the incremental parser interface.
90 - move =encoding around again, to avoid bugs with search.cpan.org.
91 when can we finally have utf-8 in pod???
92 - add ->incr_reset method.
93
942.2 Wed Apr 16 20:37:25 CEST 2008
95 - lifted the log2 rounding restriction of max_depth and max_size.
96 - make booleans mutable by creating a copy instead of handing out
97 the same scalar (reported by pasha sadri).
98 - added support for incremental json parsing (still EXPERIMENTAL).
99 - implemented and added a json_xs command line utility that can convert
100 from/to a number of serialisation formats - tell me if you need more.
101 - implement allow_unknown/get_allow_unknown methods.
102 - fixed documentation of max_depth w.r.t. higher and equal.
103 - moved down =encoding directive a bit, too much breaks if it's the first
104 pod directive :/.
105 - removed documentation section on other modules, it became somewhat
106 outdated and is nowadays mostly of historical interest.
107
1082.1 Wed Mar 19 23:23:18 CET 2008
109 - update documentation here and there: add a large section
110 about utf8/latin1/ascii flags, add a security consideration
111 and extend and clarify the JSON and YAML section.
112 - medium speed enhancements when encoding/decoding non-ascii chars.
113 - minor speedup in number encoding case.
114 - extend and clarify the section on incompatibilities
115 between YAML and JSON.
116 - switch to static inline from just inline when using gcc.
117 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
118 - fix some issues with UV to JSON conversion of unknown impact.
119 - published the yahoo locals search result used in benchmarks as the
120 original url changes so comparison is impossible.
121
1222.01 Wed Dec 5 11:40:28 CET 2007
123 - INCOMPATIBLE API CHANGE: to_json and from_json have been
124 renamed to encode_json/decode_json for JSON.pm compatibility.
125 The old functions croak and might be replaced by JSON.pm
126 comaptible versions in some later release.
127
1282.0 Tue Dec 4 11:30:46 CET 2007
129 - this is supposed to be the first version of JSON::XS
130 compatible with version 2.0+ of the JSON module.
131 Using the JSON module as frontend to JSON::XS should be
132 as fast as using JSON::XS directly, so consider using it
133 instead.
134 - added get_* methods for all "simple" options.
135 - make JSON::XS subclassable.
136
1371.53 Tue Nov 13 23:58:33 CET 2007
138 - minor doc clarifications.
139 - fixed many doc typos (patch by Thomas L. Shinnick).
140
1411.52 Mon Oct 15 03:22:06 CEST 2007
142 - remove =encoding pod directive again, it confuses too many pod
143 parsers :/.
144
1451.51 Sat Oct 13 03:55:56 CEST 2007
146 - encode empty arrays/hashes in a compact way when pretty is enabled.
147 - apparently JSON::XS was used to find some bugs in the
148 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
149 the testsuite.
150 - quite a bit of doc updates/extension.
151 - require 5.8.2, as this seems to be the first unicode-stable version.
152
1531.5 Tue Aug 28 04:05:38 CEST 2007
154 - add support for tied hashes, based on ideas and testcase by
155 Marcus Holland-Moritz.
156 - implemented relaxed parsing mode where some extensions are being
157 accepted. generation is still JSON-only.
158
1591.44 Wed Aug 22 01:02:44 CEST 2007
160 - very experimental process-emulation support, slowing everything down.
161 the horribly broken perl threads are still not supported - YMMV.
162
1631.43 Thu Jul 26 13:26:37 CEST 2007
164 - convert big json numbers exclusively consisting of digits to NV
165 only when there is no loss of precision, otherwise to string.
166
1671.42 Tue Jul 24 00:51:18 CEST 2007
168 - fix a crash caused by not handling missing array elements
169 (report and testcase by Jay Kuri).
170
1711.41 Tue Jul 10 18:21:44 CEST 2007
172 - fix compilation with NDEBUG (assert side-effect),
173 affects convert_blessed only.
174 - fix a bug in decode filters calling ENTER; SAVETMPS;
175 one time too often.
176 - catch a typical error in TO_JSON methods.
177 - antique-ised XS.xs again to work with outdated
178 C compilers (windows...).
179
1801.4 Mon Jul 2 10:06:30 CEST 2007
4 - add convert_blessed setting. 181 - add convert_blessed setting.
5 - encode did not catch all blessed objects, encoding their 182 - encode did not catch all blessed objects, encoding their
6 contents in most cases. This has been fixed by introducing 183 contents in most cases. This has been fixed by introducing
7 the allow_blessed setting. 184 the allow_blessed setting.
8 - added filter_json_object and filter_json_single_key_object 185 - added filter_json_object and filter_json_single_key_object
9 settings that specify a callback to be called when 186 settings that specify a callback to be called when
10 json objects are encountered. 187 all/specific json objects are encountered.
11 - assume that most object keys are simple ascii words and 188 - assume that most object keys are simple ascii words and
12 optimise this case, penalising the general case. This can 189 optimise this case, penalising the general case. This can
13 speed up decoding by 30% in typical cases and gives 190 speed up decoding by 30% in typical cases and gives
14 a smaller and faster perl hash. 191 a smaller and faster perl hash.
15 - implemented simpleminded, optional resource size checking 192 - implemented simpleminded, optional resource size checking

156 case the called functions do... stuff. 333 case the called functions do... stuff.
157 - croak when encoding to ascii and an out-of-range 334 - croak when encoding to ascii and an out-of-range
158 (non-unicode) codepoint is encountered. 335 (non-unicode) codepoint is encountered.

161 - the "could not sleep without debuggign release". 338 - the "could not sleep without debugging release".
162 it should basically work now, with many bugs as 339 it should basically work now, with many bugs as
163 no production tests have been run yet. 340 no production tests have been run yet.
164 - added more testcases. 341 - added more testcases.
