2 2
3TODO: maybe use some overload magic to decode true and false into something 32.3 Wed Aug 18 01:26:47 CEST 2010
4 not 0 or 1 in perl. or use attached magic? 4 - make sure decoder doesn't change the decoding in the incremental
5TODO: get rid of dynamic arrays to support so-called C compilers 5 parser (testcase provided by Hendrik Schumacher).
6 by fucking microsoft that do not do C. argl, snprintf is also 6 - applied patch by DaTa for Data::Dumper support in json_xs.
7 missing. 7 - added -t dump support to json_xs, using Data::Dump.
8TODO: latin1 flag working similar to ascii. 8 - added -f eval support to json_xs.

102.29 Wed Mar 17 02:39:12 CET 2010
11 - fix a memory leak when callbacks set using filter_json_object
12 or filter_json_single_key_object were called (great testcase
13 by Eric Wilhelm).
14
152.28 Thu Mar 11 20:30:46 CET 2010
16 - implement our own atof function - perl's can be orders of
17 magnitudes slower than even the system one. on the positive
18 side, ours seems to be more exact in general than perl's.
19 (testcase provided by Tim Meadowcroft).
20 - clarify floating point conversion issues a bit.
21 - update jpsykes csrf article url.
22 - updated benchmark section - JSON::PP became much faster!
23
242.27 Thu Jan 7 07:35:08 CET 2010
25 - support relaxed option inside the incremental parser
26 (testcase provided by IKEGAMI via Makamaka).
27
282.26 Sat Oct 10 03:26:19 CEST 2009
29 - big integers could become truncated (based on patch
30 by Strobl Anton).
31 - output format change: indent now adds a final newline, which is
32 more expected and more true to the documentation.
33
342.25 Sat Aug 8 12:04:41 CEST 2009
35 - the perl debugger completely breaks lvalue subs - try to work
36 around the issue.
37 - ignore RMAGICAL hashes w.r.t. CANONICAL.
38 - try to work around a possible char signedness issue on aix.
39 - require common sense.
40
412.24 Sat May 30 08:25:45 CEST 2009
42 - the incremental parser did not update its parse offset
43 pointer correctly when parsing utf8-strings (nicely
44 debugged by Martin Evans).
45 - appending a non-utf8-string to the incremental parser
46 in utf8 mode failed to upgrade the string.
47 - wording of parse error messages has been improved.
48
492.232 Sun Feb 22 11:12:25 CET 2009
50 - use an exponential algorithm to extend strings, to
51 help platforms with bad or abysmal==windows memory
52 allocater performance, at the expense of some memory
53 wastage (use shrink to recover this extra memory).
54 (nicely analysed by Dmitry Karasik).
55
562.2311 Thu Feb 19 02:12:54 CET 2009
57 - add a section "JSON and ECMAscript" to explain some
58 incompatibilities between the two (problem was noted by
59 various people).
60 - add t/20_faihu.t.
61
622.231 Thu Nov 20 04:59:08 CET 2008
63 - work around 5.10.0 magic bugs where manipulating magic values
64 (such as $1) would permanently damage them as perl would
65 ignore the magicalness, by making a full copy of the string,
66 reported by Dmitry Karasik.
67 - work around spurious warnings under older perl 5.8's.
68
692.23 Mon Sep 29 05:08:29 CEST 2008
70 - fix a compilation problem when perl is not using char * as, well,
71 char *.
72 - use PL_hexdigit in favour of rolling our own.
73
742.2222 Sun Jul 20 18:49:00 CEST 2008
75 - same game again, broken 5.10 finds yet another assertion
76 failure, and the workaround causes additional runtime warnings.
77 Work around the next assertion AND the warning. 5.10 seriously
78 needs to adjust it's attitude against working code.
79
802.222 Sat Jul 19 06:15:34 CEST 2008
81 - you work around one -DDEBUGGING assertion bug in perl 5.10
82 just to hit the next one. work around this one, too.
83
842.22 Tue Jul 15 13:26:51 CEST 2008
85 - allow higher nesting levels in incremental parser.
86 - error out earlier in some cases in the incremental parser
87 (as suggested by Yuval Kogman).
88 - improve incr-parser test (Yuval Kogman).
89
902.21 Tue Jun 3 08:43:23 CEST 2008
91 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
92 - remove the experimental status of the incremental parser interface.
93 - move =encoding around again, to avoid bugs with search.cpan.org.
94 when can we finally have utf-8 in pod???
95 - add ->incr_reset method.
96
972.2 Wed Apr 16 20:37:25 CEST 2008
98 - lifted the log2 rounding restriction of max_depth and max_size.
99 - make booleans mutable by creating a copy instead of handing out
100 the same scalar (reported by pasha sadri).
101 - added support for incremental json parsing (still EXPERIMENTAL).
102 - implemented and added a json_xs command line utility that can convert
103 from/to a number of serialisation formats - tell me if you need more.
104 - implement allow_unknown/get_allow_unknown methods.
105 - fixed documentation of max_depth w.r.t. higher and equal.
106 - moved down =encoding directive a bit, too much breaks if it's the first
107 pod directive :/.
108 - removed documentation section on other modules, it became somewhat
109 outdated and is nowadays mostly of historical interest.
110
1112.1 Wed Mar 19 23:23:18 CET 2008
112 - update documentation here and there: add a large section
113 about utf8/latin1/ascii flags, add a security consideration
114 and extend and clarify the JSON and YAML section.
115 - medium speed enhancements when encoding/decoding non-ascii chars.
116 - minor speedup in number encoding case.
117 - extend and clarify the section on incompatibilities
118 between YAML and JSON.
119 - switch to static inline from just inline when using gcc.
120 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
121 - fix some issues with UV to JSON conversion of unknown impact.
122 - published the yahoo locals search result used in benchmarks as the
123 original url changes so comparison is impossible.
124
1252.01 Wed Dec 5 11:40:28 CET 2007
126 - INCOMPATIBLE API CHANGE: to_json and from_json have been
127 renamed to encode_json/decode_json for JSON.pm compatibility.
128 The old functions croak and might be replaced by JSON.pm
129 comaptible versions in some later release.
130
1312.0 Tue Dec 4 11:30:46 CET 2007
132 - this is supposed to be the first version of JSON::XS
133 compatible with version 2.0+ of the JSON module.
134 Using the JSON module as frontend to JSON::XS should be
135 as fast as using JSON::XS directly, so consider using it
136 instead.
137 - added get_* methods for all "simple" options.
138 - make JSON::XS subclassable.
139
1401.53 Tue Nov 13 23:58:33 CET 2007
141 - minor doc clarifications.
142 - fixed many doc typos (patch by Thomas L. Shinnick).
143
1441.52 Mon Oct 15 03:22:06 CEST 2007
145 - remove =encoding pod directive again, it confuses too many pod
146 parsers :/.
147
1481.51 Sat Oct 13 03:55:56 CEST 2007
149 - encode empty arrays/hashes in a compact way when pretty is enabled.
150 - apparently JSON::XS was used to find some bugs in the
151 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
152 the testsuite.
153 - quite a bit of doc updates/extension.
154 - require 5.8.2, as this seems to be the first unicode-stable version.
155
1561.5 Tue Aug 28 04:05:38 CEST 2007
157 - add support for tied hashes, based on ideas and testcase by
158 Marcus Holland-Moritz.
159 - implemented relaxed parsing mode where some extensions are being
160 accepted. generation is still JSON-only.
161
1621.44 Wed Aug 22 01:02:44 CEST 2007
163 - very experimental process-emulation support, slowing everything down.
164 the horribly broken perl threads are still not supported - YMMV.
165
1661.43 Thu Jul 26 13:26:37 CEST 2007
167 - convert big json numbers exclusively consisting of digits to NV
168 only when there is no loss of precision, otherwise to string.
169
1701.42 Tue Jul 24 00:51:18 CEST 2007
171 - fix a crash caused by not handling missing array elements
172 (report and testcase by Jay Kuri).
173
1741.41 Tue Jul 10 18:21:44 CEST 2007
175 - fix compilation with NDEBUG (assert side-effect),
176 affects convert_blessed only.
177 - fix a bug in decode filters calling ENTER; SAVETMPS;
178 one time too often.
179 - catch a typical error in TO_JSON methods.
180 - antique-ised XS.xs again to work with outdated
181 C compilers (windows...).
182
1831.4 Mon Jul 2 10:06:30 CEST 2007
184 - add convert_blessed setting.
185 - encode did not catch all blessed objects, encoding their
186 contents in most cases. This has been fixed by introducing
187 the allow_blessed setting.
188 - added filter_json_object and filter_json_single_key_object
189 settings that specify a callback to be called when
190 all/specific json objects are encountered.
191 - assume that most object keys are simple ascii words and
192 optimise this case, penalising the general case. This can
193 speed up decoding by 30% in typical cases and gives
194 a smaller and faster perl hash.
195 - implemented simpleminded, optional resource size checking
196 in decode_json.
197 - remove objToJson/jsonToObj aliases, as the next version
198 of JSON will not have them either.
199 - bit the bullet and converted the very simple json object
200 into a more complex one.
201 - work around a bug where perl wrongly claims an integer
202 is not an integer.
203 - unbundle JSON::XS::Boolean into own pm file so Storable
204 and similar modules can resolve the overloading when thawing.
205
2061.3 Sun Jun 24 01:55:02 CEST 2007
207 - make JSON::XS::true and false special overloaded objects
208 and return those instead of 1 and 0 for those json atoms
209 (JSON::PP compatibility is NOT achieved yet).
210 - add JSON::XS::is_bool predicate to test for those special
211 values.
212 - add a reference to
213 http://jpsykes.com/47/practical-csrf-and-json-security.
214 - removed require 5.8.8 again, it is just not very expert-friendly.
215 Also try to be more compatible with slightly older versions,
216 which are not recommended (because they are buggy).
217
2181.24 Mon Jun 11 05:40:49 CEST 2007
219 - added informative section on JSON-as-YAML.
220 - get rid of some c99-isms again.
221 - localise dec->cur in decode_str, speeding up
222 string decoding considerably (>15% on my amd64 + gcc).
223 - increased SHORT_STRING_LEN to 16kb: stack space is
224 usually plenty, and this actually saves memory
225 when !shrinking as short strings will fit perfectly.
226
2271.23 Wed Jun 6 20:13:06 CEST 2007
228 - greatly improved small integer encoding and decoding speed.
229 - implement a number of ยต-optimisations.
230 - updated benchmarks.
231
2321.22 Thu May 24 00:07:25 CEST 2007
233 - require 5.8.8 explicitly as older perls do not seem to offer
234 the required macros.
235 - possibly made it compile on so-called C compilers by microsoft.
236
2371.21 Wed May 9 18:40:32 CEST 2007
238 - character offset reported for trailing garbage was random.
239
2401.2 Wed May 9 18:35:01 CEST 2007
241 - decode did not work with magical scalars (doh!).
242 - added latin1 flag to produce JSON texts in the latin1 subset
243 of unicode.
244 - flag trailing garbage as error.
245 - new decode_prefix method that returns the number
246 of characters consumed by a decode.
247 - max octets/char in perls UTF-X is actually 13, not 11,
248 as pointed out by Glenn Linderman.
10 - fixed typoe reported by YAMASHINA Hio. 249 - fixed typoe reported by YAMASHINA Hio.
