3TODO: allow a configurable recursion limit and/or or other forms of resource limiting (string size, memory usage...) 3 - add t/20_faihu.t.
4TODO: maybe simply use \0 and \1 as true/false when encoding (and overloaded/blessed versions thereof on
5 decoding?)

52.231 Thu Nov 20 04:59:08 CET 2008
6 - work around 5.10.0 magic bugs where manipulating magic values
7 (such as $1) would permanently damage them as perl would
8 ignore the magicalness, by making a full copy of the string,
9 reported by Dmitry Karasik.
10 - work around spurious wanrings under older perl 5.8's.
11
122.23 Mon Sep 29 05:08:29 CEST 2008
13 - fix a compilation problem when perl is not using char * as, well,
14 char *.
15 - use PL_hexdigit in favour of rolling our own.
16
172.2222 Sun Jul 20 18:49:00 CEST 2008
18 - same game again, broken 5.10 finds yet another assertion
19 failure, and the workaround causes additional runtime warnings.
20 Work around the next assertion AND the warning. 5.10 seriously
21 needs to adjust it's attitude against working code.
22
232.222 Sat Jul 19 06:15:34 CEST 2008
24 - you work around one -DDEBUGGING assertion bug in perl 5.10
25 just to hit the next one. work around this one, too.
26
272.22 Tue Jul 15 13:26:51 CEST 2008
28 - allow higher nesting levels in incremental parser.
29 - error out earlier in some cases in the incremental parser
30 (as suggested by Yuval Kogman).
31 - improve incr-parser test (Yuval Kogman).
32
332.21 Tue Jun 3 08:43:23 CEST 2008
34 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
35 - remove the experimental status of the incremental parser interface.
36 - move =encoding around again, to avoid bugs with search.cpan.org.
37 when can we finally have utf-8 in pod???
38 - add ->incr_reset method.
39
402.2 Wed Apr 16 20:37:25 CEST 2008
41 - lifted the log2 rounding restriction of max_depth and max_size.
42 - make booleans mutable by creating a copy instead of handing out
43 the same scalar (reported by pasha sadri).
44 - added support for incremental json parsing (still EXPERIMENTAL).
45 - implemented and added a json_xs command line utility that can convert
46 from/to a number of serialisation formats - tell me if you need more.
47 - implement allow_unknown/get_allow_unknown methods.
48 - fixed documentation of max_depth w.r.t. higher and equal.
49 - moved down =encoding directive a bit, too much breaks if it's the first
50 pod directive :/.
51 - removed documentation section on other modules, it became somewhat
52 outdated and is nowadays mostly of historical interest.
53
542.1 Wed Mar 19 23:23:18 CET 2008
55 - update documentation here and there: add a large section
56 about utf8/latin1/ascii flags, add a security consideration
57 and extend and clarify the JSON and YAML section.
58 - medium speed enhancements when encoding/decoding non-ascii chars.
59 - minor speedup in number encoding case.
60 - extend and clarify the section on incompatibilities
61 between YAML and JSON.
62 - switch to static inline from just inline when using gcc.
63 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
64 - fix some issues with UV to JSON conversion of unknown impact.
65 - published the yahoo locals search result used in benchmarks as the
66 original url changes so comparison is impossible.
67
682.01 Wed Dec 5 11:40:28 CET 2007
69 - INCOMPATIBLE API CHANGE: to_json and from_json have been
70 renamed to encode_json/decode_json for JSON.pm compatibility.
71 The old functions croak and might be replaced by JSON.pm
72 comaptible versions in some later release.
73
742.0 Tue Dec 4 11:30:46 CET 2007
75 - this is supposed to be the first version of JSON::XS
76 compatible with version 2.0+ of the JSON module.
77 Using the JSON module as frontend to JSON::XS should be
78 as fast as using JSON::XS directly, so consider using it
79 instead.
80 - added get_* methods for all "simple" options.
81 - make JSON::XS subclassable.
82
831.53 Tue Nov 13 23:58:33 CET 2007
84 - minor doc clarifications.
85 - fixed many doc typos (patch by Thomas L. Shinnick).
86
871.52 Mon Oct 15 03:22:06 CEST 2007
88 - remove =encoding pod directive again, it confuses too many pod
89 parsers :/.
90
911.51 Sat Oct 13 03:55:56 CEST 2007
92 - encode empty arrays/hashes in a compact way when pretty is enabled.
93 - apparently JSON::XS was used to find some bugs in the
94 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
95 the testsuite.
96 - quite a bit of doc updates/extension.
97 - require 5.8.2, as this seems to be the first unicode-stable version.
98
991.5 Tue Aug 28 04:05:38 CEST 2007
100 - add support for tied hashes, based on ideas and testcase by
101 Marcus Holland-Moritz.
102 - implemented relaxed parsing mode where some extensions are being
103 accepted. generation is still JSON-only.
104
1051.44 Wed Aug 22 01:02:44 CEST 2007
106 - very experimental process-emulation support, slowing everything down.
107 the horribly broken perl threads are still not supported - YMMV.
108
1091.43 Thu Jul 26 13:26:37 CEST 2007
110 - convert big json numbers exclusively consisting of digits to NV
111 only when there is no loss of precision, otherwise to string.
112
1131.42 Tue Jul 24 00:51:18 CEST 2007
114 - fix a crash caused by not handling missing array elements
115 (report and testcase by Jay Kuri).
116
1171.41 Tue Jul 10 18:21:44 CEST 2007
118 - fix compilation with NDEBUG (assert side-effect),
119 affects convert_blessed only.
120 - fix a bug in decode filters calling ENTER; SAVETMPS;
121 one time too often.
122 - catch a typical error in TO_JSON methods.
123 - antique-ised XS.xs again to work with outdated
124 C compilers (windows...).
125
1261.4 Mon Jul 2 10:06:30 CEST 2007
127 - add convert_blessed setting.
128 - encode did not catch all blessed objects, encoding their
129 contents in most cases. This has been fixed by introducing
130 the allow_blessed setting.
131 - added filter_json_object and filter_json_single_key_object
132 settings that specify a callback to be called when
133 all/specific json objects are encountered.
134 - assume that most object keys are simple ascii words and
135 optimise this case, penalising the general case. This can
136 speed up decoding by 30% in typical cases and gives
137 a smaller and faster perl hash.
138 - implemented simpleminded, optional resource size checking
139 in decode_json.
140 - remove objToJson/jsonToObj aliases, as the next version
141 of JSON will not have them either.
142 - bit the bullet and converted the very simple json object
143 into a more complex one.
144 - work around a bug where perl wrongly claims an integer
145 is not an integer.
146 - unbundle JSON::XS::Boolean into own pm file so Storable
147 and similar modules can resolve the overloading when thawing.
148
1491.3 Sun Jun 24 01:55:02 CEST 2007
150 - make JSON::XS::true and false special overloaded objects
151 and return those instead of 1 and 0 for those json atoms
152 (JSON::PP compatibility is NOT achieved yet).
153 - add JSON::XS::is_bool predicate to test for those special
154 values.
155 - add a reference to
156 http://jpsykes.com/47/practical-csrf-and-json-security.
157 - removed require 5.8.8 again, it is just not very expert-friendly.
158 Also try to be more compatible with slightly older versions,
159 which are not recommended (because they are buggy).
160
1611.24 Mon Jun 11 05:40:49 CEST 2007
162 - added informative section on JSON-as-YAML.
163 - get rid of some c99-isms again.
164 - localise dec->cur in decode_str, speeding up
165 string decoding considerably (>15% on my amd64 + gcc).
166 - increased SHORT_STRING_LEN to 16kb: stack space is
167 usually plenty, and this actually saves memory
168 when !shrinking as short strings will fit perfectly.
169
1701.23 Wed Jun 6 20:13:06 CEST 2007
171 - greatly improved small integer encoding and decoding speed.
172 - implement a number of ยต-optimisations.
173 - updated benchmarks.
174
1751.22 Thu May 24 00:07:25 CEST 2007
176 - require 5.8.8 explicitly as older perls do not seem to offer
177 the required macros.
178 - possibly made it compile on so-called C compilers by microsoft.
179
1801.21 Wed May 9 18:40:32 CEST 2007
181 - character offset reported for trailing garbage was random.
182
1831.2 Wed May 9 18:35:01 CEST 2007
184 - decode did not work with magical scalars (doh!).
185 - added latin1 flag to produce JSON texts in the latin1 subset
186 of unicode.
187 - flag trailing garbage as error.
188 - new decode_prefix method that returns the number
189 of characters consumed by a decode.
190 - max octets/char in perls UTF-X is actually 13, not 11,
191 as pointed out by Glenn Linderman.
192 - fixed typoe reported by YAMASHINA Hio.
193
1941.11 Mon Apr 9 07:05:49 CEST 2007
195 - properly 0-terminate sv's returned by encode to help
196 C libraries that expect that 0 to be there.
197 - partially "port" JSON from C to microsofts fucking broken
198 pseudo-C. They should be burned to the ground for pissing
199 on standards. And I should be stoned for even trying to
200 support this filthy excuse for a c compiler.
201
2021.1 Wed Apr 4 01:45:00 CEST 2007
203 - clarify documentation (pointed out by Quinn Weaver).
204 - decode_utf8 sometimes did not correctly flag errors,
205 leading to segfaults.
206 - further reduced default nesting depth to 512 due to the test
207 failure by that anonymous "chris" whose e-mail address seems
208 to be impossible to get. Tests on other freebsd systems indicate
209 that this is likely a problem in his/her configuration and not this
210 module.
211 - renamed json => JSON in error messages.
212 - corrected the character offset in some error messages.
213
2141.01 Sat Mar 31 16:15:40 CEST 2007
215 - do not segfault when from_json/decode gets passed
216 a non-string object (reported by Florian Ragwitz).
217 This has no effect on normal operation.
218
2191.0 Thu Mar 29 04:43:34 CEST 2007
220 - the long awaited (by me) 1.0 version.
221 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
222 true and false.
223 - add some more notes to shrink, as suggested by Alex Efros.
224 - improve testsuite.
225 - halve the default nesting depth limit, to hopefully make it
226 work on Freebsd (unfortunately, the cpan tester did not
227 send me his report, so I cannot ask about the stack limit on fbsd).
228
2290.8 Mon Mar 26 00:10:48 CEST 2007
230 - fix a memleak when decoding hashes.
7 - export jsonToBj and objToJson as aliases 231 - export jsonToBj and objToJson as aliases
8 to to_json and from_json, to reduce incompatibilities 232 to to_json and from_json, to reduce incompatibilities
9 between JSON/JSON::PC and JSON::XS. (experimental). 233 between JSON/JSON::PC and JSON::XS. (experimental).
234 - implement a maximum nesting depth for both en- and de-coding.
235 - added a security considerations sections.
