1Revision history for Perl extension JSON::XS 1Revision history for Perl extension JSON::XS
2 2
3TODO: object filtering (decode_filtered?) 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 - updated benchmark section - JSON::PP became much faster!
9
102.27 Thu Jan 7 07:35:08 CET 2010
11 - support relaxed option inside the incremental parser
12 (testcase provided by IKEGAMI via Makamaka).
13
142.26 Sat Oct 10 03:26:19 CEST 2009
15 - big integers could become truncated (based on patch
16 by Strobl Anton).
17 - output format change: indent now adds a final newline, which is
18 more expected and more true to the documentation.
19
202.25 Sat Aug 8 12:04:41 CEST 2009
21 - the perl debugger completely breaks lvalue subs - try to work
22 around the issue.
23 - ignore RMAGICAL hashes w.r.t. CANONICAL.
24 - try to work around a possible char signedness issue on aix.
25 - require common sense.
26
272.24 Sat May 30 08:25:45 CEST 2009
28 - the incremental parser did not update its parse offset
29 pointer correctly when parsing utf8-strings (nicely
30 debugged by Martin Evans).
31 - appending a non-utf8-string to the incremental parser
32 in utf8 mode failed to upgrade the string.
33 - wording of parse error messages has been improved.
34
352.232 Sun Feb 22 11:12:25 CET 2009
36 - use an exponential algorithm to extend strings, to
37 help platforms with bad or abysmal==windows memory
38 allocater performance, at the expense of some memory
39 wastage (use shrink to recover this extra memory).
40 (nicely analysed by Dmitry Karasik).
41
422.2311 Thu Feb 19 02:12:54 CET 2009
43 - add a section "JSON and ECMAscript" to explain some
44 incompatibilities between the two (problem was noted by
45 various people).
46 - add t/20_faihu.t.
47
482.231 Thu Nov 20 04:59:08 CET 2008
49 - work around 5.10.0 magic bugs where manipulating magic values
50 (such as $1) would permanently damage them as perl would
51 ignore the magicalness, by making a full copy of the string,
52 reported by Dmitry Karasik.
53 - work around spurious warnings under older perl 5.8's.
54
552.23 Mon Sep 29 05:08:29 CEST 2008
56 - fix a compilation problem when perl is not using char * as, well,
57 char *.
58 - use PL_hexdigit in favour of rolling our own.
59
602.2222 Sun Jul 20 18:49:00 CEST 2008
61 - same game again, broken 5.10 finds yet another assertion
62 failure, and the workaround causes additional runtime warnings.
63 Work around the next assertion AND the warning. 5.10 seriously
64 needs to adjust it's attitude against working code.
65
662.222 Sat Jul 19 06:15:34 CEST 2008
67 - you work around one -DDEBUGGING assertion bug in perl 5.10
68 just to hit the next one. work around this one, too.
69
702.22 Tue Jul 15 13:26:51 CEST 2008
71 - allow higher nesting levels in incremental parser.
72 - error out earlier in some cases in the incremental parser
73 (as suggested by Yuval Kogman).
74 - improve incr-parser test (Yuval Kogman).
75
762.21 Tue Jun 3 08:43:23 CEST 2008
77 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
78 - remove the experimental status of the incremental parser interface.
79 - move =encoding around again, to avoid bugs with search.cpan.org.
80 when can we finally have utf-8 in pod???
81 - add ->incr_reset method.
82
832.2 Wed Apr 16 20:37:25 CEST 2008
84 - lifted the log2 rounding restriction of max_depth and max_size.
85 - make booleans mutable by creating a copy instead of handing out
86 the same scalar (reported by pasha sadri).
87 - added support for incremental json parsing (still EXPERIMENTAL).
88 - implemented and added a json_xs command line utility that can convert
89 from/to a number of serialisation formats - tell me if you need more.
90 - implement allow_unknown/get_allow_unknown methods.
91 - fixed documentation of max_depth w.r.t. higher and equal.
92 - moved down =encoding directive a bit, too much breaks if it's the first
93 pod directive :/.
94 - removed documentation section on other modules, it became somewhat
95 outdated and is nowadays mostly of historical interest.
96
972.1 Wed Mar 19 23:23:18 CET 2008
98 - update documentation here and there: add a large section
99 about utf8/latin1/ascii flags, add a security consideration
100 and extend and clarify the JSON and YAML section.
101 - medium speed enhancements when encoding/decoding non-ascii chars.
102 - minor speedup in number encoding case.
103 - extend and clarify the section on incompatibilities
104 between YAML and JSON.
105 - switch to static inline from just inline when using gcc.
106 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
107 - fix some issues with UV to JSON conversion of unknown impact.
108 - published the yahoo locals search result used in benchmarks as the
109 original url changes so comparison is impossible.
110
1112.01 Wed Dec 5 11:40:28 CET 2007
112 - INCOMPATIBLE API CHANGE: to_json and from_json have been
113 renamed to encode_json/decode_json for JSON.pm compatibility.
114 The old functions croak and might be replaced by JSON.pm
115 comaptible versions in some later release.
116
1172.0 Tue Dec 4 11:30:46 CET 2007
118 - this is supposed to be the first version of JSON::XS
119 compatible with version 2.0+ of the JSON module.
120 Using the JSON module as frontend to JSON::XS should be
121 as fast as using JSON::XS directly, so consider using it
122 instead.
123 - added get_* methods for all "simple" options.
124 - make JSON::XS subclassable.
125
1261.53 Tue Nov 13 23:58:33 CET 2007
127 - minor doc clarifications.
128 - fixed many doc typos (patch by Thomas L. Shinnick).
129
1301.52 Mon Oct 15 03:22:06 CEST 2007
131 - remove =encoding pod directive again, it confuses too many pod
132 parsers :/.
133
1341.51 Sat Oct 13 03:55:56 CEST 2007
135 - encode empty arrays/hashes in a compact way when pretty is enabled.
136 - apparently JSON::XS was used to find some bugs in the
137 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
138 the testsuite.
139 - quite a bit of doc updates/extension.
140 - require 5.8.2, as this seems to be the first unicode-stable version.
141
1421.5 Tue Aug 28 04:05:38 CEST 2007
143 - add support for tied hashes, based on ideas and testcase by
144 Marcus Holland-Moritz.
145 - implemented relaxed parsing mode where some extensions are being
146 accepted. generation is still JSON-only.
147
1481.44 Wed Aug 22 01:02:44 CEST 2007
149 - very experimental process-emulation support, slowing everything down.
150 the horribly broken perl threads are still not supported - YMMV.
151
1521.43 Thu Jul 26 13:26:37 CEST 2007
153 - convert big json numbers exclusively consisting of digits to NV
154 only when there is no loss of precision, otherwise to string.
155
1561.42 Tue Jul 24 00:51:18 CEST 2007
157 - fix a crash caused by not handling missing array elements
158 (report and testcase by Jay Kuri).
159
1601.41 Tue Jul 10 18:21:44 CEST 2007
161 - fix compilation with NDEBUG (assert side-effect),
162 affects convert_blessed only.
163 - fix a bug in decode filters calling ENTER; SAVETMPS;
164 one time too often.
165 - catch a typical error in TO_JSON methods.
166 - antique-ised XS.xs again to work with outdated
167 C compilers (windows...).
168
1691.4 Mon Jul 2 10:06:30 CEST 2007
5 - add convert_blessed setting. 170 - add convert_blessed setting.
6 - encode did not catch all blessed objects, encoding their 171 - encode did not catch all blessed objects, encoding their
7 contents in most cases. This has been fixed by introducing 172 contents in most cases. This has been fixed by introducing
8 the allow_blessed setting. 173 the allow_blessed setting.
9 - added filter_json_object and filter_json_single_key_object 174 - added filter_json_object and filter_json_single_key_object
10 settings that specify a callback to be called when 175 settings that specify a callback to be called when
11 json objects are encountered. 176 all/specific json objects are encountered.
12 - assume that most object keys are simple ascii words and 177 - assume that most object keys are simple ascii words and
13 optimise this case, penalising the general case. This can 178 optimise this case, penalising the general case. This can
14 speed up decoding by 30% in typical cases and gives 179 speed up decoding by 30% in typical cases and gives
15 a smaller and faster perl hash. 180 a smaller and faster perl hash.
16 - implemented simpleminded, optional resource size checking 181 - implemented simpleminded, optional resource size checking

157 case the called functions do... stuff. 322 case the called functions do... stuff.
158 - croak when encoding to ascii and an out-of-range 323 - croak when encoding to ascii and an out-of-range
159 (non-unicode) codepoint is encountered. 324 (non-unicode) codepoint is encountered.

162 - the "could not sleep without debuggign release". 327 - the "could not sleep without debugging release".
163 it should basically work now, with many bugs as 328 it should basically work now, with many bugs as
164 no production tests have been run yet. 329 no production tests have been run yet.
165 - added more testcases. 330 - added more testcases.
166 - the expected shitload of bugfixes. 331 - the expected shitload of bugfixes.
167 - handle utf8 flag correctly in decode. 332 - handle utf8 flag correctly in decode.
