3TODO: allow a configurable recursion limit and/or or other forms of resource limiting (string size, memory usage...) 32.2222 Sun Jul 20 18:49:00 CEST 2008
4TODO: maybe simply use \0 and \1 as true/false when encoding (and overloaded/blessed versions thereof on 4 - same game again, broken 5.10 finds yet another assertion
5 decoding?) 5 failure, and the workaround causes additional runtime warnings.
6 Work around the next assertion AND the warning. 5.10 seriously
7 needs to adjust it's attitude against working code.
8
92.222 Sat Jul 19 06:15:34 CEST 2008
10 - you work around one -DDEBUGGING assertion bug in perl 5.10
11 just to hit the next one. work around this one, too.
12
132.22 Tue Jul 15 13:26:51 CEST 2008
14 - allow higher nesting levels in incremental parser.
15 - error out earlier in some cases in the incremental parser
16 (as suggested by Yuval Kogman).
17 - improve incr-parser test (Yuval Kogman).
18
192.21 Tue Jun 3 08:43:23 CEST 2008
20 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
21 - remove the experimental status of the incremental parser interface.
22 - move =encoding around again, to avoid bugs with search.cpan.org.
23 when can we finally have utf-8 in pod???
24 - add ->incr_reset method.
25
262.2 Wed Apr 16 20:37:25 CEST 2008
27 - lifted the log2 rounding restriction of max_depth and max_size.
28 - make booleans mutable by creating a copy instead of handing out
29 the same scalar (reported by pasha sadri).
30 - added support for incremental json parsing (still EXPERIMENTAL).
31 - implemented and added a json_xs command line utility that can convert
32 from/to a number of serialisation formats - tell me if you need more.
33 - implement allow_unknown/get_allow_unknown methods.
34 - fixed documentation of max_depth w.r.t. higher and equal.
35 - moved down =encoding directive a bit, too much breaks if it's the first
36 pod directive :/.
37 - removed documentation section on other modules, it became somewhat
38 outdated and is nowadays mostly of historical interest.
39
402.1 Wed Mar 19 23:23:18 CET 2008
41 - update documentation here and there: add a large section
42 about utf8/latin1/ascii flags, add a security consideration
43 and extend and clarify the JSON and YAML section.
44 - medium speed enhancements when encoding/decoding non-ascii chars.
45 - minor speedup in number encoding case.
46 - extend and clarify the section on incompatibilities
47 between YAML and JSON.
48 - switch to static inline from just inline when using gcc.
49 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
50 - fix some issues with UV to JSON conversion of unknown impact.
51 - published the yahoo locals search result used in benchmarks as the
52 original url changes so comparison is impossible.
53
542.01 Wed Dec 5 11:40:28 CET 2007
55 - INCOMPATIBLE API CHANGE: to_json and from_json have been
56 renamed to encode_json/decode_json for JSON.pm compatibility.
57 The old functions croak and might be replaced by JSON.pm
58 comaptible versions in some later release.
59
602.0 Tue Dec 4 11:30:46 CET 2007
61 - this is supposed to be the first version of JSON::XS
62 compatible with version 2.0+ of the JSON module.
63 Using the JSON module as frontend to JSON::XS should be
64 as fast as using JSON::XS directly, so consider using it
65 instead.
66 - added get_* methods for all "simple" options.
67 - make JSON::XS subclassable.
68
691.53 Tue Nov 13 23:58:33 CET 2007
70 - minor doc clarifications.
71 - fixed many doc typos (patch by Thomas L. Shinnick).
72
731.52 Mon Oct 15 03:22:06 CEST 2007
74 - remove =encoding pod directive again, it confuses too many pod
75 parsers :/.
76
771.51 Sat Oct 13 03:55:56 CEST 2007
78 - encode empty arrays/hashes in a compact way when pretty is enabled.
79 - apparently JSON::XS was used to find some bugs in the
80 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
81 the testsuite.
82 - quite a bit of doc updates/extension.
83 - require 5.8.2, as this seems to be the first unicode-stable version.
84
851.5 Tue Aug 28 04:05:38 CEST 2007
86 - add support for tied hashes, based on ideas and testcase by
87 Marcus Holland-Moritz.
88 - implemented relaxed parsing mode where some extensions are being
89 accepted. generation is still JSON-only.
90
911.44 Wed Aug 22 01:02:44 CEST 2007
92 - very experimental process-emulation support, slowing everything down.
93 the horribly broken perl threads are still not supported - YMMV.
94
951.43 Thu Jul 26 13:26:37 CEST 2007
96 - convert big json numbers exclusively consisting of digits to NV
97 only when there is no loss of precision, otherwise to string.
98
991.42 Tue Jul 24 00:51:18 CEST 2007
100 - fix a crash caused by not handling missing array elements
101 (report and testcase by Jay Kuri).
102
1031.41 Tue Jul 10 18:21:44 CEST 2007
104 - fix compilation with NDEBUG (assert side-effect),
105 affects convert_blessed only.
106 - fix a bug in decode filters calling ENTER; SAVETMPS;
107 one time too often.
108 - catch a typical error in TO_JSON methods.
109 - antique-ised XS.xs again to work with outdated
110 C compilers (windows...).
111
1121.4 Mon Jul 2 10:06:30 CEST 2007
113 - add convert_blessed setting.
114 - encode did not catch all blessed objects, encoding their
115 contents in most cases. This has been fixed by introducing
116 the allow_blessed setting.
117 - added filter_json_object and filter_json_single_key_object
118 settings that specify a callback to be called when
119 all/specific json objects are encountered.
120 - assume that most object keys are simple ascii words and
121 optimise this case, penalising the general case. This can
122 speed up decoding by 30% in typical cases and gives
123 a smaller and faster perl hash.
124 - implemented simpleminded, optional resource size checking
125 in decode_json.
126 - remove objToJson/jsonToObj aliases, as the next version
127 of JSON will not have them either.
128 - bit the bullet and converted the very simple json object
129 into a more complex one.
130 - work around a bug where perl wrongly claims an integer
131 is not an integer.
132 - unbundle JSON::XS::Boolean into own pm file so Storable
133 and similar modules can resolve the overloading when thawing.
134
1351.3 Sun Jun 24 01:55:02 CEST 2007
136 - make JSON::XS::true and false special overloaded objects
137 and return those instead of 1 and 0 for those json atoms
138 (JSON::PP compatibility is NOT achieved yet).
139 - add JSON::XS::is_bool predicate to test for those special
140 values.
141 - add a reference to
142 http://jpsykes.com/47/practical-csrf-and-json-security.
143 - removed require 5.8.8 again, it is just not very expert-friendly.
144 Also try to be more compatible with slightly older versions,
145 which are not recommended (because they are buggy).
146
1471.24 Mon Jun 11 05:40:49 CEST 2007
148 - added informative section on JSON-as-YAML.
149 - get rid of some c99-isms again.
150 - localise dec->cur in decode_str, speeding up
151 string decoding considerably (>15% on my amd64 + gcc).
152 - increased SHORT_STRING_LEN to 16kb: stack space is
153 usually plenty, and this actually saves memory
154 when !shrinking as short strings will fit perfectly.
155
1561.23 Wed Jun 6 20:13:06 CEST 2007
157 - greatly improved small integer encoding and decoding speed.
158 - implement a number of µ-optimisations.
159 - updated benchmarks.
160
1611.22 Thu May 24 00:07:25 CEST 2007
162 - require 5.8.8 explicitly as older perls do not seem to offer
163 the required macros.
164 - possibly made it compile on so-called C compilers by microsoft.
165
1661.21 Wed May 9 18:40:32 CEST 2007
167 - character offset reported for trailing garbage was random.
168
1691.2 Wed May 9 18:35:01 CEST 2007
170 - decode did not work with magical scalars (doh!).
171 - added latin1 flag to produce JSON texts in the latin1 subset
172 of unicode.
173 - flag trailing garbage as error.
174 - new decode_prefix method that returns the number
175 of characters consumed by a decode.
176 - max octets/char in perls UTF-X is actually 13, not 11,
177 as pointed out by Glenn Linderman.
178 - fixed typoe reported by YAMASHINA Hio.
179
1801.11 Mon Apr 9 07:05:49 CEST 2007
181 - properly 0-terminate sv's returned by encode to help
182 C libraries that expect that 0 to be there.
183 - partially "port" JSON from C to microsofts fucking broken
184 pseudo-C. They should be burned to the ground for pissing
185 on standards. And I should be stoned for even trying to
186 support this filthy excuse for a c compiler.
187
1881.1 Wed Apr 4 01:45:00 CEST 2007
189 - clarify documentation (pointed out by Quinn Weaver).
190 - decode_utf8 sometimes did not correctly flag errors,
191 leading to segfaults.
192 - further reduced default nesting depth to 512 due to the test
193 failure by that anonymous "chris" whose e-mail address seems
194 to be impossible to get. Tests on other freebsd systems indicate
195 that this is likely a problem in his/her configuration and not this
196 module.
197 - renamed json => JSON in error messages.
198 - corrected the character offset in some error messages.
199
2001.01 Sat Mar 31 16:15:40 CEST 2007
201 - do not segfault when from_json/decode gets passed
202 a non-string object (reported by Florian Ragwitz).
203 This has no effect on normal operation.
204
2051.0 Thu Mar 29 04:43:34 CEST 2007
206 - the long awaited (by me) 1.0 version.
207 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
208 true and false.
209 - add some more notes to shrink, as suggested by Alex Efros.
210 - improve testsuite.
211 - halve the default nesting depth limit, to hopefully make it
212 work on Freebsd (unfortunately, the cpan tester did not
213 send me his report, so I cannot ask about the stack limit on fbsd).
214
2150.8 Mon Mar 26 00:10:48 CEST 2007
216 - fix a memleak when decoding hashes.
217 - export jsonToBj and objToJson as aliases
218 to to_json and from_json, to reduce incompatibilities
219 between JSON/JSON::PC and JSON::XS. (experimental).
220 - implement a maximum nesting depth for both en- and de-coding.
221 - added a security considerations sections.
222
2230.7 Sun Mar 25 01:46:30 CET 2007
224 - code cleanup.
225 - fix a memory overflow bug when indenting.
226 - pretty-printing now up to 15% faster.
227 - improve decoding speed of strings by
228 up to 50% by specialcasing short strings.
229 - further decoding speedups for strings using
230 lots of \u escapes.
231 - improve utf8 decoding speed for U+80 .. U+7FF.
232
2330.5 Sat Mar 24 20:41:51 CET 2007
234 - added the UTF-16 encoding example hinted at in previous
235 versions.
236 - minor documentation fixes.
237 - fix a bug in and optimise canonicalising fastpath
238 (reported by Craig Manley).
239 - remove a subtest that breaks with bleadperl (reported
240 by Andreas König).
