32     - implemented an object tagging extension (using the
33 root 1.159 Types::Serialiser serialisation protocol).
34     - reworked the documentation regarding object serialisation,
35 root 1.165 add a new OBJECT SERIALISATION section that explains th

42 root 1.155 2.34 Thu May 23 11:30:34 CEST 2013
43     - work around bugs in perl 5.18 breaking more than 100
44     widely used modules, without a fix in sight because
45     p5pers don't care about CPAN anymore.
46 root 1.154 - when canonicalising, only allocate up to 64 hash key
47     pointers on the stack. for larger hashes, use the heap,
48     to avoid using too much stackspace.
49 root 1.155 - discuss the problem with setlocale (reported by a few victims).
50 root 1.154
51 root 1.153 2.33 Wed Aug 1 21:03:52 CEST 2012
52     - internal encode/decode XS wrappers did not expect stack

61 root 1.153 - don't accumulate initial whitespace in the incremental buffer
62 root 1.149 (this can be useful to allow whitespace-keepalive on a tcp
63     connection without triggering the max_size limit).
64 root 1.148 - properly croak on some invalid inputs that are not strings
65     (e.g. undef) when trying to decode a json text (reported
66     and analyzed by Goro Fuji).
67    
68 root 1.146 2.3 Wed Aug 18 01:26:47 CEST 2010
69     - make sure decoder doesn't change the decoding in the incremental
70     parser (testcase provided by Hendrik Schumacher).
71 root 1.144 - applied patch by DaTa for Data::Dumper support in json_xs.
72 root 1.145 - added -t dump support to json_xs, using Data::Dump.

74 root 1.144
75 root 1.143 2.29 Wed Mar 17 02:39:12 CET 2010
76     - fix a memory leak when callbacks set using filter_json_object
77     or filter_json_single_key_object were called (great testcase
78     by Eric Wilhelm).
79    
80 root 1.142 2.28 Thu Mar 11 20:30:46 CET 2010
81 root 1.139 - implement our own atof function - perl's can be orders of
82     magnitudes slower than even the system one. on the positive
83     side, ours seems to be more exact in general than perl's.
84     (testcase provided by Tim Meadowcroft).
85 root 1.142 - clarify floating point conversion issues a bit.
86 root 1.138 - update jpsykes csrf article url.
87 root 1.140 - updated benchmark section - JSON::PP became much faster!
88 root 1.138
89 root 1.137 2.27 Thu Jan 7 07:35:08 CET 2010
90 root 1.136 - support relaxed option inside the incremental parser

92 root 1.136
93 root 1.135 2.26 Sat Oct 10 03:26:19 CEST 2009
94     - big integers could become truncated (based on patch

97     more expected and more true to the documentation.
98 root 1.132
99 root 1.131 2.25 Sat Aug 8 12:04:41 CEST 2009
100     - the perl debugger completely breaks lvalue subs - try to work
101     around the issue.
102 root 1.130 - ignore RMAGICAL hashes w.r.t. CANONICAL.
103 root 1.128 - try to work around a possible char signedness issue on aix.
104 root 1.129 - require common sense.
105 root 1.128
106 root 1.127 2.24 Sat May 30 08:25:45 CEST 2009
107     - the incremental parser did not update its parse offset
108     pointer correctly when parsing utf8-strings (nicely
109     debugged by Martin Evans).
110     - appending a non-utf8-string to the incremental parser
111     in utf8 mode failed to upgrade the string.
112     - wording of parse error messages has been improved.
113    
114 root 1.126 2.232 Sun Feb 22 11:12:25 CET 2009
115 root 1.125 - use an exponential algorithm to extend strings, to
116 root 1.126 help platforms with bad or abysmal==windows memory
117     allocater performance, at the expense of some memory
118 root 1.125 wastage (use shrink to recover this extra memory).
119     (nicely analysed by Dmitry Karasik).
120    
121 root 1.124 2.2311 Thu Feb 19 02:12:54 CET 2009
122 root 1.123 - add a section "JSON and ECMAscript" to explain some
123     incompatibilities between the two (problem was noted by
124     various people).
125 root 1.122 - add t/20_faihu.t.
126    
127 root 1.121 2.231 Thu Nov 20 04:59:08 CET 2008
128     - work around 5.10.0 magic bugs where manipulating magic values
129     (such as $1) would permanently damage them as perl would
130     ignore the magicalness, by making a full copy of the string,
131     reported by Dmitry Karasik.
132 root 1.125 - work around spurious warnings under older perl 5.8's.
133 root 1.121
134 root 1.120 2.23 Mon Sep 29 05:08:29 CEST 2008
135     - fix a compilation problem when perl is not using char * as, well,
136     char *.
137 root 1.119 - use PL_hexdigit in favour of rolling our own.
138    
139 root 1.118 2.2222 Sun Jul 20 18:49:00 CEST 2008
140     - same game again, broken 5.10 finds yet another assertion
141     failure, and the workaround causes additional runtime warnings.
142     Work around the next assertion AND the warning. 5.10 seriously
143     needs to adjust it's attitude against working code.
144    
145 root 1.117 2.222 Sat Jul 19 06:15:34 CEST 2008
146     - you work around one -DDEBUGGING assertion bug in perl 5.10
147     just to hit the next one. work around this one, too.
148    
149 root 1.116 2.22 Tue Jul 15 13:26:51 CEST 2008
150 root 1.115 - allow higher nesting levels in incremental parser.
151     - error out earlier in some cases in the incremental parser
152     (as suggested by Yuval Kogman).
153     - improve incr-parser test (Yuval Kogman).
154    
155 root 1.114 2.21 Tue Jun 3 08:43:23 CEST 2008
156     - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
157 root 1.112 - remove the experimental status of the incremental parser interface.
158 root 1.111 - move =encoding around again, to avoid bugs with search.cpan.org.
159     when can we finally have utf-8 in pod???
160 root 1.113 - add ->incr_reset method.
161 root 1.111
162 root 1.110 2.2 Wed Apr 16 20:37:25 CEST 2008
163 root 1.109 - lifted the log2 rounding restriction of max_depth and max_size.
164 root 1.107 - make booleans mutable by creating a copy instead of handing out
165     the same scalar (reported by pasha sadri).
166 root 1.164 - added support for incremental json parsing (still EXPERIMENTAL).
167 root 1.103 - implemented and added a json_xs command line utility that can convert
168     from/to a number of serialisation formats - tell me if you need more.
169 root 1.108 - implement allow_unknown/get_allow_unknown methods.
170 root 1.109 - fixed documentation of max_depth w.r.t. higher and equal.
171 root 1.112 - moved down =encoding directive a bit, too much breaks if it's the first
172 root 1.102 pod directive :/.
173 root 1.106 - removed documentation section on other modules, it became somewhat
174     outdated and is nowadays mostly of historical interest.
175 root 1.102
176 root 1.101 2.1 Wed Mar 19 23:23:18 CET 2008
177     - update documentation here and there: add a large section
178     about utf8/latin1/ascii flags, add a security consideration
179     and extend and clarify the JSON and YAML section.
180 root 1.98 - medium speed enhancements when encoding/decoding non-ascii chars.
181 root 1.100 - minor speedup in number encoding case.
182 root 1.92 - extend and clarify the section on incompatibilities
183     between YAML and JSON.
184 root 1.95 - switch to static inline from just inline when using gcc.
185 root 1.94 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
186 root 1.100 - fix some issues with UV to JSON conversion of unknown impact.
187 root 1.99 - published the yahoo locals search result used in benchmarks as the
188     original url changes so comparison is impossible.
189 root 1.92
190 root 1.91 2.01 Wed Dec 5 11:40:28 CET 2007
191     - INCOMPATIBLE API CHANGE: to_json and from_json have been
192     renamed to encode_json/decode_json for JSON.pm compatibility.
193     The old functions croak and might be replaced by JSON.pm
194     comaptible versions in some later release.
195    
196 root 1.90 2.0 Tue Dec 4 11:30:46 CET 2007
197     - this is supposed to be the first version of JSON::XS
198     compatible with version 2.0+ of the JSON module.
199     Using the JSON module as frontend to JSON::XS should be
200     as fast as using JSON::XS directly, so consider using it
201     instead.
202 root 1.88 - added get_* methods for all "simple" options.
203 root 1.89 - make JSON::XS subclassable.
204 root 1.88
205 root 1.86 1.53 Tue Nov 13 23:58:33 CET 2007
206 root 1.85 - minor doc clarifications.
207     - fixed many doc typos (patch by Thomas L. Shinnick).
208    
209 root 1.84 1.52 Mon Oct 15 03:22:06 CEST 2007
210 root 1.83 - remove =encoding pod directive again, it confuses too many pod
211     parsers :/.
212    
213 root 1.82 1.51 Sat Oct 13 03:55:56 CEST 2007
214 root 1.81 - encode empty arrays/hashes in a compact way when pretty is enabled.
215 root 1.87 - apparently JSON::XS was used to find some bugs in the
216 root 1.80 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
217     the testsuite.
218     - quite a bit of doc updates/extension.
219 root 1.79 - require 5.8.2, as this seems to be the first unicode-stable version.
220 root 1.78
221 root 1.77 1.5 Tue Aug 28 04:05:38 CEST 2007
222 root 1.74 - add support for tied hashes, based on ideas and testcase by
223     Marcus Holland-Moritz.
224 root 1.75 - implemented relaxed parsing mode where some extensions are being
225     accepted. generation is still JSON-only.
226 root 1.74
227     1.44 Wed Aug 22 01:02:44 CEST 2007
228 root 1.73 - very experimental process-emulation support, slowing everything down.
229     the horribly broken perl threads are still not supported - YMMV.
230    
231 root 1.72 1.43 Thu Jul 26 13:26:37 CEST 2007
232     - convert big json numbers exclusively consisting of digits to NV
233     only when there is no loss of precision, otherwise to string.
234    
235 root 1.71 1.42 Tue Jul 24 00:51:18 CEST 2007
236     - fix a crash caused by not handling missing array elements
237     (report and testcase by Jay Kuri).
238    
239 root 1.70 1.41 Tue Jul 10 18:21:44 CEST 2007
240     - fix compilation with NDEBUG (assert side-effect),
241     affects convert_blessed only.
242 root 1.69 - fix a bug in decode filters calling ENTER; SAVETMPS;
243     one time too often.
244 root 1.70 - catch a typical error in TO_JSON methods.
245 root 1.69 - antique-ised XS.xs again to work with outdated
246     C compilers (windows...).
247    
248 root 1.68 1.4 Mon Jul 2 10:06:30 CEST 2007
249 root 1.63 - add convert_blessed setting.
250 root 1.56 - encode did not catch all blessed objects, encoding their
251     contents in most cases. This has been fixed by introducing
252     the allow_blessed setting.
253 root 1.65 - added filter_json_object and filter_json_single_key_object
254     settings that specify a callback to be called when
255 root 1.67 all/specific json objects are encountered.
256 root 1.59 - assume that most object keys are simple ascii words and
257     optimise this case, penalising the general case. This can
258     speed up decoding by 30% in typical cases and gives
259     a smaller and faster perl hash.
260 root 1.58 - implemented simpleminded, optional resource size checking
261     in decode_json.
262 root 1.61 - remove objToJson/jsonToObj aliases, as the next version
263     of JSON will not have them either.
264 root 1.62 - bit the bullet and converted the very simple json object
265     into a more complex one.
266 root 1.64 - work around a bug where perl wrongly claims an integer
267     is not an integer.
268 root 1.65 - unbundle JSON::XS::Boolean into own pm file so Storable
269     and similar modules can resolve the overloading when thawing.
270 root 1.56
271 root 1.55 1.3 Sun Jun 24 01:55:02 CEST 2007
272 root 1.54 - make JSON::XS::true and false special overloaded objects
273     and return those instead of 1 and 0 for those json atoms
274     (JSON::PP compatibility is NOT achieved yet).
275     - add JSON::XS::is_bool predicate to test for those special
276     values.
277 root 1.52 - add a reference to
278     http://jpsykes.com/47/practical-csrf-and-json-security.
279 root 1.60 - removed require 5.8.8 again, it is just not very expert-friendly.
280     Also try to be more compatible with slightly older versions,
281 root 1.54 which are not recommended (because they are buggy).
282 root 1.52
283 root 1.51 1.24 Mon Jun 11 05:40:49 CEST 2007
284 root 1.49 - added informative section on JSON-as-YAML.
285 root 1.51 - get rid of some c99-isms again.
286 root 1.50 - localise dec->cur in decode_str, speeding up
287     string decoding considerably (>15% on my amd64 + gcc).
288     - increased SHORT_STRING_LEN to 16kb: stack space is
289     usually plenty, and this actually saves memory
290 root 1.51 when !shrinking as short strings will fit perfectly.
291 root 1.49
292 root 1.47 1.23 Wed Jun 6 20:13:06 CEST 2007
293 root 1.46 - greatly improved small integer encoding and decoding speed.
294     - implement a number of µ-optimisations.
295 root 1.47 - updated benchmarks.
296 root 1.46
297 root 1.45 1.22 Thu May 24 00:07:25 CEST 2007
298 root 1.42 - require 5.8.8 explicitly as older perls do not seem to offer
299     the required macros.
300 root 1.43 - possibly made it compile on so-called C compilers by microsoft.
301 root 1.42
302 root 1.41 1.21 Wed May 9 18:40:32 CEST 2007
303 root 1.47 - character offset reported for trailing garbage was random.
304 root 1.41
305 root 1.40 1.2 Wed May 9 18:35:01 CEST 2007
306     - decode did not work with magical scalars (doh!).
307 root 1.38 - added latin1 flag to produce JSON texts in the latin1 subset
308     of unicode.
309 root 1.39 - flag trailing garbage as error.
310     - new decode_prefix method that returns the number
311     of characters consumed by a decode.
312 root 1.40 - max octets/char in perls UTF-X is actually 13, not 11,
313     as pointed out by Glenn Linderman.
314     - fixed typoe reported by YAMASHINA Hio.
315 root 1.34
316 root 1.32 1.11 Mon Apr 9 07:05:49 CEST 2007
317     - properly 0-terminate sv's returned by encode to help
318     C libraries that expect that 0 to be there.
319 root 1.31 - partially "port" JSON from C to microsofts fucking broken
320     pseudo-C. They should be burned to the ground for pissing
321     on standards. And I should be stoned for even trying to
322 root 1.32 support this filthy excuse for a c compiler.
323 root 1.6
324 root 1.30 1.1 Wed Apr 4 01:45:00 CEST 2007
325 root 1.28 - clarify documentation (pointed out by Quinn Weaver).
326 root 1.29 - decode_utf8 sometimes did not correctly flag errors,
327     leading to segfaults.
328 root 1.30 - further reduced default nesting depth to 512 due to the test
329     failure by that anonymous "chris" whose e-mail address seems
330     to be impossible to get. Tests on other freebsd systems indicate
331     that this is likely a problem in his/her configuration and not this
332     module.
333     - renamed json => JSON in error messages.
334     - corrected the character offset in some error messages.
335 root 1.28
336 root 1.27 1.01 Sat Mar 31 16:15:40 CEST 2007
337     - do not segfault when from_json/decode gets passed
338     a non-string object (reported by Florian Ragwitz).
339     This has no effect on normal operation.
340    
341 root 1.25 1.0 Thu Mar 29 04:43:34 CEST 2007
342     - the long awaited (by me) 1.0 version.
343     - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
344     true and false.
345 root 1.24 - add some more notes to shrink, as suggested by Alex Efros.
346 root 1.25 - improve testsuite.
347 root 1.26 - halve the default nesting depth limit, to hopefully make it
348 root 1.25 work on Freebsd (unfortunately, the cpan tester did not
349     send me his report, so I cannot ask about the stack limit on fbsd).
350 root 1.24
351 root 1.23 0.8 Mon Mar 26 00:10:48 CEST 2007
352 root 1.21 - fix a memleak when decoding hashes.
353 root 1.20 - export jsonToBj and objToJson as aliases
354     to to_json and from_json, to reduce incompatibilities
355     between JSON/JSON::PC and JSON::XS. (experimental).
356 root 1.21 - implement a maximum nesting depth for both en- and de-coding.
357     - added a security considerations sections.
358 root 1.20
359 root 1.19 0.7 Sun Mar 25 01:46:30 CET 2007
360 root 1.16 - code cleanup.
361     - fix a memory overflow bug when indenting.
362     - pretty-printing now up to 15% faster.
363     - improve decoding speed of strings by
364     up to 50% by specialcasing short strings.
365     - further decoding speedups for strings using
366     lots of \u escapes.
367 root 1.17 - improve utf8 decoding speed for U+80 .. U+7FF.
368 root 1.16
369 root 1.15 0.5 Sat Mar 24 20:41:51 CET 2007
370 root 1.14 - added the UTF-16 encoding example hinted at in previous
371     versions.
372     - minor documentation fixes.
