4 not 0 or 1 in perl. or use attached magic?

52.25 Sat Aug 8 12:04:41 CEST 2009
6 - the perl debugger completely breaks lvalue subs - try to work
7 around the issue.
8 - ignore RMAGICAL hashes w.r.t. CANONICAL.
9 - try to work around a possible char signedness issue on aix.
10 - require common sense.
11
122.24 Sat May 30 08:25:45 CEST 2009
13 - the incremental parser did not update its parse offset
14 pointer correctly when parsing utf8-strings (nicely
15 debugged by Martin Evans).
16 - appending a non-utf8-string to the incremental parser
17 in utf8 mode failed to upgrade the string.
18 - wording of parse error messages has been improved.
19
202.232 Sun Feb 22 11:12:25 CET 2009
21 - use an exponential algorithm to extend strings, to
22 help platforms with bad or abysmal==windows memory
23 allocater performance, at the expense of some memory
24 wastage (use shrink to recover this extra memory).
25 (nicely analysed by Dmitry Karasik).
26
272.2311 Thu Feb 19 02:12:54 CET 2009
28 - add a section "JSON and ECMAscript" to explain some
29 incompatibilities between the two (problem was noted by
30 various people).
31 - add t/20_faihu.t.
32
332.231 Thu Nov 20 04:59:08 CET 2008
34 - work around 5.10.0 magic bugs where manipulating magic values
35 (such as $1) would permanently damage them as perl would
36 ignore the magicalness, by making a full copy of the string,
37 reported by Dmitry Karasik.
38 - work around spurious warnings under older perl 5.8's.
39
402.23 Mon Sep 29 05:08:29 CEST 2008
41 - fix a compilation problem when perl is not using char * as, well,
42 char *.
43 - use PL_hexdigit in favour of rolling our own.
44
452.2222 Sun Jul 20 18:49:00 CEST 2008
46 - same game again, broken 5.10 finds yet another assertion
47 failure, and the workaround causes additional runtime warnings.
48 Work around the next assertion AND the warning. 5.10 seriously
49 needs to adjust it's attitude against working code.
50
512.222 Sat Jul 19 06:15:34 CEST 2008
52 - you work around one -DDEBUGGING assertion bug in perl 5.10
53 just to hit the next one. work around this one, too.
54
552.22 Tue Jul 15 13:26:51 CEST 2008
56 - allow higher nesting levels in incremental parser.
57 - error out earlier in some cases in the incremental parser
58 (as suggested by Yuval Kogman).
59 - improve incr-parser test (Yuval Kogman).
60
612.21 Tue Jun 3 08:43:23 CEST 2008
62 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
63 - remove the experimental status of the incremental parser interface.
64 - move =encoding around again, to avoid bugs with search.cpan.org.
65 when can we finally have utf-8 in pod???
66 - add ->incr_reset method.
67
682.2 Wed Apr 16 20:37:25 CEST 2008
69 - lifted the log2 rounding restriction of max_depth and max_size.
70 - make booleans mutable by creating a copy instead of handing out
71 the same scalar (reported by pasha sadri).
72 - added support for incremental json parsing (still EXPERIMENTAL).
73 - implemented and added a json_xs command line utility that can convert
74 from/to a number of serialisation formats - tell me if you need more.
75 - implement allow_unknown/get_allow_unknown methods.
76 - fixed documentation of max_depth w.r.t. higher and equal.
77 - moved down =encoding directive a bit, too much breaks if it's the first
78 pod directive :/.
79 - removed documentation section on other modules, it became somewhat
80 outdated and is nowadays mostly of historical interest.
81
822.1 Wed Mar 19 23:23:18 CET 2008
83 - update documentation here and there: add a large section
84 about utf8/latin1/ascii flags, add a security consideration
85 and extend and clarify the JSON and YAML section.
86 - medium speed enhancements when encoding/decoding non-ascii chars.
87 - minor speedup in number encoding case.
88 - extend and clarify the section on incompatibilities
89 between YAML and JSON.
90 - switch to static inline from just inline when using gcc.
91 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
92 - fix some issues with UV to JSON conversion of unknown impact.
93 - published the yahoo locals search result used in benchmarks as the
94 original url changes so comparison is impossible.
95
962.01 Wed Dec 5 11:40:28 CET 2007
97 - INCOMPATIBLE API CHANGE: to_json and from_json have been
98 renamed to encode_json/decode_json for JSON.pm compatibility.
99 The old functions croak and might be replaced by JSON.pm
100 comaptible versions in some later release.
101
1022.0 Tue Dec 4 11:30:46 CET 2007
103 - this is supposed to be the first version of JSON::XS
104 compatible with version 2.0+ of the JSON module.
105 Using the JSON module as frontend to JSON::XS should be
106 as fast as using JSON::XS directly, so consider using it
107 instead.
108 - added get_* methods for all "simple" options.
109 - make JSON::XS subclassable.
110
1111.53 Tue Nov 13 23:58:33 CET 2007
112 - minor doc clarifications.
113 - fixed many doc typos (patch by Thomas L. Shinnick).
114
1151.52 Mon Oct 15 03:22:06 CEST 2007
116 - remove =encoding pod directive again, it confuses too many pod
117 parsers :/.
118
1191.51 Sat Oct 13 03:55:56 CEST 2007
120 - encode empty arrays/hashes in a compact way when pretty is enabled.
121 - apparently JSON::XS was used to find some bugs in the
122 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
123 the testsuite.
124 - quite a bit of doc updates/extension.
125 - require 5.8.2, as this seems to be the first unicode-stable version.
126
1271.5 Tue Aug 28 04:05:38 CEST 2007
128 - add support for tied hashes, based on ideas and testcase by
129 Marcus Holland-Moritz.
130 - implemented relaxed parsing mode where some extensions are being
131 accepted. generation is still JSON-only.
132
1331.44 Wed Aug 22 01:02:44 CEST 2007
134 - very experimental process-emulation support, slowing everything down.
135 the horribly broken perl threads are still not supported - YMMV.
136
1371.43 Thu Jul 26 13:26:37 CEST 2007
138 - convert big json numbers exclusively consisting of digits to NV
139 only when there is no loss of precision, otherwise to string.
140
1411.42 Tue Jul 24 00:51:18 CEST 2007
142 - fix a crash caused by not handling missing array elements
143 (report and testcase by Jay Kuri).
144
1451.41 Tue Jul 10 18:21:44 CEST 2007
146 - fix compilation with NDEBUG (assert side-effect),
147 affects convert_blessed only.
148 - fix a bug in decode filters calling ENTER; SAVETMPS;
149 one time too often.
150 - catch a typical error in TO_JSON methods.
151 - antique-ised XS.xs again to work with outdated
152 C compilers (windows...).
153
1541.4 Mon Jul 2 10:06:30 CEST 2007
155 - add convert_blessed setting.
156 - encode did not catch all blessed objects, encoding their
157 contents in most cases. This has been fixed by introducing
158 the allow_blessed setting.
159 - added filter_json_object and filter_json_single_key_object
160 settings that specify a callback to be called when
161 all/specific json objects are encountered.
162 - assume that most object keys are simple ascii words and
163 optimise this case, penalising the general case. This can
164 speed up decoding by 30% in typical cases and gives
165 a smaller and faster perl hash.
166 - implemented simpleminded, optional resource size checking
167 in decode_json.
168 - remove objToJson/jsonToObj aliases, as the next version
169 of JSON will not have them either.
170 - bit the bullet and converted the very simple json object
171 into a more complex one.
172 - work around a bug where perl wrongly claims an integer
173 is not an integer.
174 - unbundle JSON::XS::Boolean into own pm file so Storable
175 and similar modules can resolve the overloading when thawing.
176
1771.3 Sun Jun 24 01:55:02 CEST 2007
178 - make JSON::XS::true and false special overloaded objects
179 and return those instead of 1 and 0 for those json atoms
180 (JSON::PP compatibility is NOT achieved yet).
181 - add JSON::XS::is_bool predicate to test for those special
182 values.
6 - add a reference to 183 - add a reference to
7 http://jpsykes.com/47/practical-csrf-and-json-security. 184 http://jpsykes.com/47/practical-csrf-and-json-security.
185 - removed require 5.8.8 again, it is just not very expert-friendly.
186 Also try to be more compatible with slightly older versions,
187 which are not recommended (because they are buggy).

91.24 Mon Jun 11 05:40:49 CEST 2007 1891.24 Mon Jun 11 05:40:49 CEST 2007

127 case the called functions do... stuff. 307 case the called functions do... stuff.
128 - croak when encoding to ascii and an out-of-range 308 - croak when encoding to ascii and an out-of-range
