1Revision history for Perl extension JSON::XS 1Revision history for Perl extension JSON::XS
2 2
30.3 3 - make booleans mutable by creating a copy instead of handing out
4 the same scalar (reported by pasha sadri).
5 - added support for incremental json parsing (still EXPERIMENTAL).
6 - implemented and added a json_xs command line utility that can convert
7 from/to a number of serialisation formats - tell me if you need more.
8 - moved down =encoding directive a bit, too much breaks if its the first
9 pod directive :/.
10 - removed documentation section on other modules, it became somewhat
11 outdated and is nowadays mostly of historical interest.
12
132.1 Wed Mar 19 23:23:18 CET 2008
14 - update documentation here and there: add a large section
15 about utf8/latin1/ascii flags, add a security consideration
16 and extend and clarify the JSON and YAML section.
17 - medium speed enhancements when encoding/decoding non-ascii chars.
18 - minor speedup in number encoding case.
19 - extend and clarify the section on incompatibilities
20 between YAML and JSON.
21 - switch to static inline from just inline when using gcc.
22 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
23 - fix some issues with UV to JSON conversion of unknown impact.
24 - published the yahoo locals search result used in benchmarks as the
25 original url changes so comparison is impossible.
26
272.01 Wed Dec 5 11:40:28 CET 2007
28 - INCOMPATIBLE API CHANGE: to_json and from_json have been
29 renamed to encode_json/decode_json for JSON.pm compatibility.
30 The old functions croak and might be replaced by JSON.pm
31 comaptible versions in some later release.
32
332.0 Tue Dec 4 11:30:46 CET 2007
34 - this is supposed to be the first version of JSON::XS
35 compatible with version 2.0+ of the JSON module.
36 Using the JSON module as frontend to JSON::XS should be
37 as fast as using JSON::XS directly, so consider using it
38 instead.
39 - added get_* methods for all "simple" options.
40 - make JSON::XS subclassable.
41
421.53 Tue Nov 13 23:58:33 CET 2007
43 - minor doc clarifications.
44 - fixed many doc typos (patch by Thomas L. Shinnick).
45
461.52 Mon Oct 15 03:22:06 CEST 2007
47 - remove =encoding pod directive again, it confuses too many pod
48 parsers :/.
49
501.51 Sat Oct 13 03:55:56 CEST 2007
51 - encode empty arrays/hashes in a compact way when pretty is enabled.
52 - apparently JSON::XS was used to find some bugs in the
53 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
54 the testsuite.
55 - quite a bit of doc updates/extension.
56 - require 5.8.2, as this seems to be the first unicode-stable version.
57
581.5 Tue Aug 28 04:05:38 CEST 2007
59 - add support for tied hashes, based on ideas and testcase by
60 Marcus Holland-Moritz.
61 - implemented relaxed parsing mode where some extensions are being
62 accepted. generation is still JSON-only.
63
641.44 Wed Aug 22 01:02:44 CEST 2007
65 - very experimental process-emulation support, slowing everything down.
66 the horribly broken perl threads are still not supported - YMMV.
67
681.43 Thu Jul 26 13:26:37 CEST 2007
69 - convert big json numbers exclusively consisting of digits to NV
70 only when there is no loss of precision, otherwise to string.
71
721.42 Tue Jul 24 00:51:18 CEST 2007
73 - fix a crash caused by not handling missing array elements
74 (report and testcase by Jay Kuri).
75
761.41 Tue Jul 10 18:21:44 CEST 2007
77 - fix compilation with NDEBUG (assert side-effect),
78 affects convert_blessed only.
79 - fix a bug in decode filters calling ENTER; SAVETMPS;
80 one time too often.
81 - catch a typical error in TO_JSON methods.
82 - antique-ised XS.xs again to work with outdated
83 C compilers (windows...).
84
851.4 Mon Jul 2 10:06:30 CEST 2007
86 - add convert_blessed setting.
87 - encode did not catch all blessed objects, encoding their
88 contents in most cases. This has been fixed by introducing
89 the allow_blessed setting.
90 - added filter_json_object and filter_json_single_key_object
91 settings that specify a callback to be called when
92 all/specific json objects are encountered.
93 - assume that most object keys are simple ascii words and
94 optimise this case, penalising the general case. This can
95 speed up decoding by 30% in typical cases and gives
96 a smaller and faster perl hash.
97 - implemented simpleminded, optional resource size checking
98 in decode_json.
99 - remove objToJson/jsonToObj aliases, as the next version
100 of JSON will not have them either.
101 - bit the bullet and converted the very simple json object
102 into a more complex one.
103 - work around a bug where perl wrongly claims an integer
104 is not an integer.
105 - unbundle JSON::XS::Boolean into own pm file so Storable
106 and similar modules can resolve the overloading when thawing.
107
1081.3 Sun Jun 24 01:55:02 CEST 2007
109 - make JSON::XS::true and false special overloaded objects
110 and return those instead of 1 and 0 for those json atoms
111 (JSON::PP compatibility is NOT achieved yet).
112 - add JSON::XS::is_bool predicate to test for those special
113 values.
114 - add a reference to
115 http://jpsykes.com/47/practical-csrf-and-json-security.
116 - removed require 5.8.8 again, it is just not very expert-friendly.
117 Also try to be more compatible with slightly older versions,
118 which are not recommended (because they are buggy).
119
1201.24 Mon Jun 11 05:40:49 CEST 2007
121 - added informative section on JSON-as-YAML.
122 - get rid of some c99-isms again.
123 - localise dec->cur in decode_str, speeding up
124 string decoding considerably (>15% on my amd64 + gcc).
125 - increased SHORT_STRING_LEN to 16kb: stack space is
126 usually plenty, and this actually saves memory
127 when !shrinking as short strings will fit perfectly.
128
1291.23 Wed Jun 6 20:13:06 CEST 2007
130 - greatly improved small integer encoding and decoding speed.
131 - implement a number of µ-optimisations.
132 - updated benchmarks.
133
1341.22 Thu May 24 00:07:25 CEST 2007
135 - require 5.8.8 explicitly as older perls do not seem to offer
136 the required macros.
137 - possibly made it compile on so-called C compilers by microsoft.
138
1391.21 Wed May 9 18:40:32 CEST 2007
140 - character offset reported for trailing garbage was random.
141
1421.2 Wed May 9 18:35:01 CEST 2007
143 - decode did not work with magical scalars (doh!).
144 - added latin1 flag to produce JSON texts in the latin1 subset
145 of unicode.
146 - flag trailing garbage as error.
147 - new decode_prefix method that returns the number
148 of characters consumed by a decode.
149 - max octets/char in perls UTF-X is actually 13, not 11,
150 as pointed out by Glenn Linderman.
151 - fixed typoe reported by YAMASHINA Hio.
152
1531.11 Mon Apr 9 07:05:49 CEST 2007
154 - properly 0-terminate sv's returned by encode to help
155 C libraries that expect that 0 to be there.
156 - partially "port" JSON from C to microsofts fucking broken
157 pseudo-C. They should be burned to the ground for pissing
158 on standards. And I should be stoned for even trying to
159 support this filthy excuse for a c compiler.
160
1611.1 Wed Apr 4 01:45:00 CEST 2007
162 - clarify documentation (pointed out by Quinn Weaver).
163 - decode_utf8 sometimes did not correctly flag errors,
164 leading to segfaults.
165 - further reduced default nesting depth to 512 due to the test
166 failure by that anonymous "chris" whose e-mail address seems
167 to be impossible to get. Tests on other freebsd systems indicate
168 that this is likely a problem in his/her configuration and not this
169 module.
170 - renamed json => JSON in error messages.
171 - corrected the character offset in some error messages.
172
1731.01 Sat Mar 31 16:15:40 CEST 2007
174 - do not segfault when from_json/decode gets passed
175 a non-string object (reported by Florian Ragwitz).
176 This has no effect on normal operation.
177
1781.0 Thu Mar 29 04:43:34 CEST 2007
179 - the long awaited (by me) 1.0 version.
180 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
181 true and false.
182 - add some more notes to shrink, as suggested by Alex Efros.
183 - improve testsuite.
184 - halve the default nesting depth limit, to hopefully make it
185 work on Freebsd (unfortunately, the cpan tester did not
186 send me his report, so I cannot ask about the stack limit on fbsd).
187
1880.8 Mon Mar 26 00:10:48 CEST 2007
189 - fix a memleak when decoding hashes.
190 - export jsonToBj and objToJson as aliases
191 to to_json and from_json, to reduce incompatibilities
192 between JSON/JSON::PC and JSON::XS. (experimental).
193 - implement a maximum nesting depth for both en- and de-coding.
194 - added a security considerations sections.
195
1960.7 Sun Mar 25 01:46:30 CET 2007
197 - code cleanup.
198 - fix a memory overflow bug when indenting.
199 - pretty-printing now up to 15% faster.
200 - improve decoding speed of strings by
201 up to 50% by specialcasing short strings.
202 - further decoding speedups for strings using
203 lots of \u escapes.
204 - improve utf8 decoding speed for U+80 .. U+7FF.
205
2060.5 Sat Mar 24 20:41:51 CET 2007
207 - added the UTF-16 encoding example hinted at in previous
208 versions.
209 - minor documentation fixes.
210 - fix a bug in and optimise canonicalising fastpath
211 (reported by Craig Manley).
212 - remove a subtest that breaks with bleadperl (reported
213 by Andreas König).
214
2150.31 Sat Mar 24 02:14:34 CET 2007
216 - documentation updates.
217 - do some casting to hopefully fix Andreas' problem.
218 - nuke bogus json rpc stuff.
219
2200.3 Fri Mar 23 19:33:21 CET 2007
4 - remove spurious PApp::Util reference (John McNamara). 221 - remove spurious PApp::Util reference (John McNamara).
5 - adapted lots of tests from other json modules 222 - adapted lots of tests from other json modules
6 (idea by Chris Carline). 223 (idea by Chris Carline).
224 - documented mapping from json to perl and vice versa.
225 - improved the documentation by adding more examples.
7 - added short escaping forms, reducing the created 226 - added short escaping forms, reducing the created
8 json texts a bit. 227 json texts a bit.
9 - added shrink flag. 228 - added shrink flag.
10 - when flag methods are called without enable argument 229 - when flag methods are called without enable argument
11 they will by default enable their flag. 230 they will by default enable their flag.
12 - considerably improved string encoding speed (at least 231 - considerably improved string encoding speed (at least
13 with gcc 4). 232 with gcc 4).
233 - added a test that covers lots of different characters.
234 - clarified some error messages.
235 - error messages now use correct character offset
236 with F_UTF8.
237 - improve the "no bytes" and "no warnings" hacks in
238 case the called functions do... stuff.
239 - croak when encoding to ascii and an out-of-range
240 (non-unicode) codepoint is encountered.
