1Revision history for Perl extension JSON::XS 1Revision history for Perl extension JSON::XS
2 2
3TODO: maybe use some overload magic to decode true and false into something 3TODO: maybe detetc and croak on more invalid inputs (e.g. +-inf/nan)
4 not 0 or 1 in perl. or use attached magic? 4TODO: maybe avoid the reblessing and better support readonly objects.
5TODO: get rid of dynamic arrays to support so-called C compilers 5TODO: http://stevehanov.ca/blog/index.php?id=104 compression
6 by fucking microsoft that do not do C. argl, snprintf is also
7 missing.

72.33 Wed Aug 1 21:03:52 CEST 2012
8 - internal encode/decode XS wrappers did not expect stack
9 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
10 - add bencode as to/from option in bin/json_xs.
11 - add -e option to json_xs, and none and string in/out formats.
12
132.32 Thu Aug 11 19:06:38 CEST 2011
14 - fix a bug in the initial whitespace accumulation.
15
162.31 Wed Jul 27 17:53:05 CEST 2011
17 - don't accumulate initial whitespace in the incremental buffer
18 (this can be useful to allow whitespace-keepalive on a tcp
19 connection without triggering the max_size limit).
20 - properly croak on some invalid inputs that are not strings
21 (e.g. undef) when trying to decode a json text (reported
22 and analyzed by Goro Fuji).
23
242.3 Wed Aug 18 01:26:47 CEST 2010
25 - make sure decoder doesn't change the decoding in the incremental
26 parser (testcase provided by Hendrik Schumacher).
27 - applied patch by DaTa for Data::Dumper support in json_xs.
28 - added -t dump support to json_xs, using Data::Dump.
29 - added -f eval support to json_xs.
30
312.29 Wed Mar 17 02:39:12 CET 2010
32 - fix a memory leak when callbacks set using filter_json_object
33 or filter_json_single_key_object were called (great testcase
34 by Eric Wilhelm).
35
362.28 Thu Mar 11 20:30:46 CET 2010
37 - implement our own atof function - perl's can be orders of
38 magnitudes slower than even the system one. on the positive
39 side, ours seems to be more exact in general than perl's.
40 (testcase provided by Tim Meadowcroft).
41 - clarify floating point conversion issues a bit.
42 - update jpsykes csrf article url.
43 - updated benchmark section - JSON::PP became much faster!
44
452.27 Thu Jan 7 07:35:08 CET 2010
46 - support relaxed option inside the incremental parser
47 (testcase provided by IKEGAMI via Makamaka).
48
492.26 Sat Oct 10 03:26:19 CEST 2009
50 - big integers could become truncated (based on patch
51 by Strobl Anton).
52 - output format change: indent now adds a final newline, which is
53 more expected and more true to the documentation.
54
552.25 Sat Aug 8 12:04:41 CEST 2009
56 - the perl debugger completely breaks lvalue subs - try to work
57 around the issue.
58 - ignore RMAGICAL hashes w.r.t. CANONICAL.
59 - try to work around a possible char signedness issue on aix.
60 - require common sense.
61
622.24 Sat May 30 08:25:45 CEST 2009
63 - the incremental parser did not update its parse offset
64 pointer correctly when parsing utf8-strings (nicely
65 debugged by Martin Evans).
66 - appending a non-utf8-string to the incremental parser
67 in utf8 mode failed to upgrade the string.
68 - wording of parse error messages has been improved.
69
702.232 Sun Feb 22 11:12:25 CET 2009
71 - use an exponential algorithm to extend strings, to
72 help platforms with bad or abysmal==windows memory
73 allocater performance, at the expense of some memory
74 wastage (use shrink to recover this extra memory).
75 (nicely analysed by Dmitry Karasik).
76
772.2311 Thu Feb 19 02:12:54 CET 2009
78 - add a section "JSON and ECMAscript" to explain some
79 incompatibilities between the two (problem was noted by
80 various people).
81 - add t/20_faihu.t.
82
832.231 Thu Nov 20 04:59:08 CET 2008
84 - work around 5.10.0 magic bugs where manipulating magic values
85 (such as $1) would permanently damage them as perl would
86 ignore the magicalness, by making a full copy of the string,
87 reported by Dmitry Karasik.
88 - work around spurious warnings under older perl 5.8's.
89
902.23 Mon Sep 29 05:08:29 CEST 2008
91 - fix a compilation problem when perl is not using char * as, well,
92 char *.
93 - use PL_hexdigit in favour of rolling our own.
94
952.2222 Sun Jul 20 18:49:00 CEST 2008
96 - same game again, broken 5.10 finds yet another assertion
97 failure, and the workaround causes additional runtime warnings.
98 Work around the next assertion AND the warning. 5.10 seriously
99 needs to adjust it's attitude against working code.
100
1012.222 Sat Jul 19 06:15:34 CEST 2008
102 - you work around one -DDEBUGGING assertion bug in perl 5.10
103 just to hit the next one. work around this one, too.
104
1052.22 Tue Jul 15 13:26:51 CEST 2008
106 - allow higher nesting levels in incremental parser.
107 - error out earlier in some cases in the incremental parser
108 (as suggested by Yuval Kogman).
109 - improve incr-parser test (Yuval Kogman).
110
1112.21 Tue Jun 3 08:43:23 CEST 2008
112 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
113 - remove the experimental status of the incremental parser interface.
114 - move =encoding around again, to avoid bugs with search.cpan.org.
115 when can we finally have utf-8 in pod???
116 - add ->incr_reset method.
117
1182.2 Wed Apr 16 20:37:25 CEST 2008
119 - lifted the log2 rounding restriction of max_depth and max_size.
120 - make booleans mutable by creating a copy instead of handing out
121 the same scalar (reported by pasha sadri).
122 - added support for incremental json parsing (still EXPERIMENTAL).
123 - implemented and added a json_xs command line utility that can convert
124 from/to a number of serialisation formats - tell me if you need more.
125 - implement allow_unknown/get_allow_unknown methods.
126 - fixed documentation of max_depth w.r.t. higher and equal.
127 - moved down =encoding directive a bit, too much breaks if it's the first
128 pod directive :/.
129 - removed documentation section on other modules, it became somewhat
130 outdated and is nowadays mostly of historical interest.
131
1322.1 Wed Mar 19 23:23:18 CET 2008
133 - update documentation here and there: add a large section
134 about utf8/latin1/ascii flags, add a security consideration
135 and extend and clarify the JSON and YAML section.
136 - medium speed enhancements when encoding/decoding non-ascii chars.
137 - minor speedup in number encoding case.
138 - extend and clarify the section on incompatibilities
139 between YAML and JSON.
140 - switch to static inline from just inline when using gcc.
141 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
142 - fix some issues with UV to JSON conversion of unknown impact.
143 - published the yahoo locals search result used in benchmarks as the
144 original url changes so comparison is impossible.
145
1462.01 Wed Dec 5 11:40:28 CET 2007
147 - INCOMPATIBLE API CHANGE: to_json and from_json have been
148 renamed to encode_json/decode_json for JSON.pm compatibility.
149 The old functions croak and might be replaced by JSON.pm
150 comaptible versions in some later release.
151
1522.0 Tue Dec 4 11:30:46 CET 2007
153 - this is supposed to be the first version of JSON::XS
154 compatible with version 2.0+ of the JSON module.
155 Using the JSON module as frontend to JSON::XS should be
156 as fast as using JSON::XS directly, so consider using it
157 instead.
158 - added get_* methods for all "simple" options.
159 - make JSON::XS subclassable.
160
1611.53 Tue Nov 13 23:58:33 CET 2007
162 - minor doc clarifications.
163 - fixed many doc typos (patch by Thomas L. Shinnick).
164
1651.52 Mon Oct 15 03:22:06 CEST 2007
166 - remove =encoding pod directive again, it confuses too many pod
167 parsers :/.
168
1691.51 Sat Oct 13 03:55:56 CEST 2007
170 - encode empty arrays/hashes in a compact way when pretty is enabled.
171 - apparently JSON::XS was used to find some bugs in the
172 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
173 the testsuite.
174 - quite a bit of doc updates/extension.
175 - require 5.8.2, as this seems to be the first unicode-stable version.
176
1771.5 Tue Aug 28 04:05:38 CEST 2007
178 - add support for tied hashes, based on ideas and testcase by
179 Marcus Holland-Moritz.
180 - implemented relaxed parsing mode where some extensions are being
181 accepted. generation is still JSON-only.
182
1831.44 Wed Aug 22 01:02:44 CEST 2007
184 - very experimental process-emulation support, slowing everything down.
185 the horribly broken perl threads are still not supported - YMMV.
186
1871.43 Thu Jul 26 13:26:37 CEST 2007
188 - convert big json numbers exclusively consisting of digits to NV
189 only when there is no loss of precision, otherwise to string.
190
1911.42 Tue Jul 24 00:51:18 CEST 2007
192 - fix a crash caused by not handling missing array elements
193 (report and testcase by Jay Kuri).
194
1951.41 Tue Jul 10 18:21:44 CEST 2007
196 - fix compilation with NDEBUG (assert side-effect),
197 affects convert_blessed only.
198 - fix a bug in decode filters calling ENTER; SAVETMPS;
199 one time too often.
200 - catch a typical error in TO_JSON methods.
201 - antique-ised XS.xs again to work with outdated
202 C compilers (windows...).
203
2041.4 Mon Jul 2 10:06:30 CEST 2007
205 - add convert_blessed setting.
206 - encode did not catch all blessed objects, encoding their
207 contents in most cases. This has been fixed by introducing
208 the allow_blessed setting.
209 - added filter_json_object and filter_json_single_key_object
210 settings that specify a callback to be called when
211 all/specific json objects are encountered.
212 - assume that most object keys are simple ascii words and
213 optimise this case, penalising the general case. This can
214 speed up decoding by 30% in typical cases and gives
215 a smaller and faster perl hash.
216 - implemented simpleminded, optional resource size checking
217 in decode_json.
218 - remove objToJson/jsonToObj aliases, as the next version
219 of JSON will not have them either.
220 - bit the bullet and converted the very simple json object
221 into a more complex one.
222 - work around a bug where perl wrongly claims an integer
223 is not an integer.
224 - unbundle JSON::XS::Boolean into own pm file so Storable
225 and similar modules can resolve the overloading when thawing.
226
2271.3 Sun Jun 24 01:55:02 CEST 2007
228 - make JSON::XS::true and false special overloaded objects
229 and return those instead of 1 and 0 for those json atoms
230 (JSON::PP compatibility is NOT achieved yet).
231 - add JSON::XS::is_bool predicate to test for those special
232 values.
233 - add a reference to
234 http://jpsykes.com/47/practical-csrf-and-json-security.
235 - removed require 5.8.8 again, it is just not very expert-friendly.
236 Also try to be more compatible with slightly older versions,
237 which are not recommended (because they are buggy).
238
2391.24 Mon Jun 11 05:40:49 CEST 2007
240 - added informative section on JSON-as-YAML.
241 - get rid of some c99-isms again.
242 - localise dec->cur in decode_str, speeding up
243 string decoding considerably (>15% on my amd64 + gcc).
244 - increased SHORT_STRING_LEN to 16kb: stack space is
245 usually plenty, and this actually saves memory
246 when !shrinking as short strings will fit perfectly.
247
2481.23 Wed Jun 6 20:13:06 CEST 2007
249 - greatly improved small integer encoding and decoding speed.
250 - implement a number of ยต-optimisations.
251 - updated benchmarks.
252
2531.22 Thu May 24 00:07:25 CEST 2007
