13
14TODO: document & testcase ->boolean_values (aristoteles).
154.0
16 - SECURITY IMPLICATION: this release enables allow_nonref by default
17 for compatibnility with RFC 7159 and newer. See "old" vs. "new"
18 JSON under SECURITY CONSIDERATIONS.
19 - reworked the "old" vs. "new" JSON section.
20 - add ->boolean_values to provide the values to which booleans
21 decode (requested by Aristotle Pagaltzis).
22 - decode would wrongly accept ASCII NUL characters instead of
23 reporting them as trailing garbage.
24 - work around what smells like a perl bug w.r.t. exceptions
25 thrown in callbacks.
26 - incremental parser now more or less respects allow_nonref.
27 - json_xs json-pretty now enables canonical mode.
28 - add documentation section about I-JSON.
29 - minor documentation fixes/updates.
30
313.04 Thu Aug 17 04:30:47 CEST 2017
32 - change exponential realloc algorithm on encoding and string decoding to be
33 really exponential (this helps slow/debugging allocators such as libumem)
34 (reported by Matthew Horsfall).
35 - string encoding would needlessly overallocate output space
36 (testcase by Matthew Horsfall).
37 - be very paranoid about extending buffer lengths and croak if buffers get too large,
38 which might (or might not) improve security.
39 - add cbor-packed type to json_xs.
40 - switch from YAML to YAML::XS in json_xs, as YAML is way too buggy and outdated.
41
423.03 Wed Nov 16 20:20:59 CET 2016
43 - fix a bug introduced by a perl bug workaround that would cause
44 incremental parsing to fail with a sv_chop panic.
45 - json_xs: toformat failure error message fixed.
46 - json_xs: allow cyclic data structures in CBOR.
47
483.02 Fri Feb 26 22:45:20 CET 2016
49 - allow_nonref now affects booleans (\1, $Types::Serialiser::Boolean)
50 as well (reported by Alex Efros).
51 - allow literal tabs in strings in relaxed mode (patch by
52 lubo.rintel@gooddata.com).
53 - support "cbor" format in json_xs tool.
54 - support (and fix) calling encode and decode in list context
55 (reported by Вадим Власов).
56 - work around a bug in older perls crashing when presented
57 with shared hash keys (Reini Urban).
58 - use stability canary.
59
603.01 Tue Oct 29 16:55:15 CET 2013
61 - backport to perls < 5.18 (reported by Paul Howarth).
62
633.0 Tue Oct 29 01:35:37 CET 2013
64 - implemented an object tagging extension (using the
65 Types::Serialiser serialisation protocol).
66 - reworked the documentation regarding object serialisation,
67 add a new OBJECT SERIALISATION section that explains th
68 whole process.
69 - new setting: allow_tags.
70 - switch to Types::Serialiser booleans.
71 - remove to_json/from_json.
72 - other minor improvements to the documentation.
73
742.34 Thu May 23 11:30:34 CEST 2013
75 - work around bugs in perl 5.18 breaking more than 100
76 widely used modules, without a fix in sight because
77 p5pers don't care about CPAN anymore.
78 - when canonicalising, only allocate up to 64 hash key
79 pointers on the stack. for larger hashes, use the heap,
80 to avoid using too much stackspace.
81 - discuss the problem with setlocale (reported by a few victims).
82
832.33 Wed Aug 1 21:03:52 CEST 2012
84 - internal encode/decode XS wrappers did not expect stack
85 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
86 - add bencode as to/from option in bin/json_xs.
87 - add -e option to json_xs, and none and string in/out formats.
88
892.32 Thu Aug 11 19:06:38 CEST 2011
90 - fix a bug in the initial whitespace accumulation.
91
922.31 Wed Jul 27 17:53:05 CEST 2011
93 - don't accumulate initial whitespace in the incremental buffer
94 (this can be useful to allow whitespace-keepalive on a tcp
95 connection without triggering the max_size limit).
96 - properly croak on some invalid inputs that are not strings
97 (e.g. undef) when trying to decode a json text (reported
98 and analyzed by Goro Fuji).
99
1002.3 Wed Aug 18 01:26:47 CEST 2010
101 - make sure decoder doesn't change the decoding in the incremental
102 parser (testcase provided by Hendrik Schumacher).
103 - applied patch by DaTa for Data::Dumper support in json_xs.
104 - added -t dump support to json_xs, using Data::Dump.
105 - added -f eval support to json_xs.
106
1072.29 Wed Mar 17 02:39:12 CET 2010
108 - fix a memory leak when callbacks set using filter_json_object
109 or filter_json_single_key_object were called (great testcase
110 by Eric Wilhelm).
111
1122.28 Thu Mar 11 20:30:46 CET 2010
113 - implement our own atof function - perl's can be orders of
114 magnitudes slower than even the system one. on the positive
115 side, ours seems to be more exact in general than perl's.
116 (testcase provided by Tim Meadowcroft).
117 - clarify floating point conversion issues a bit.
118 - update jpsykes csrf article url.
119 - updated benchmark section - JSON::PP became much faster!
120
1212.27 Thu Jan 7 07:35:08 CET 2010
122 - support relaxed option inside the incremental parser
123 (testcase provided by IKEGAMI via Makamaka).
124
1252.26 Sat Oct 10 03:26:19 CEST 2009
126 - big integers could become truncated (based on patch
127 by Strobl Anton).
128 - output format change: indent now adds a final newline, which is
129 more expected and more true to the documentation.
130
1312.25 Sat Aug 8 12:04:41 CEST 2009
132 - the perl debugger completely breaks lvalue subs - try to work
133 around the issue.
134 - ignore RMAGICAL hashes w.r.t. CANONICAL.
135 - try to work around a possible char signedness issue on aix.
136 - require common sense.
137
1382.24 Sat May 30 08:25:45 CEST 2009
139 - the incremental parser did not update its parse offset
140 pointer correctly when parsing utf8-strings (nicely
141 debugged by Martin Evans).
142 - appending a non-utf8-string to the incremental parser
143 in utf8 mode failed to upgrade the string.
144 - wording of parse error messages has been improved.
145
1462.232 Sun Feb 22 11:12:25 CET 2009
147 - use an exponential algorithm to extend strings, to
148 help platforms with bad or abysmal==windows memory
149 allocater performance, at the expense of some memory
150 wastage (use shrink to recover this extra memory).
151 (nicely analysed by Dmitry Karasik).
152
1532.2311 Thu Feb 19 02:12:54 CET 2009
154 - add a section "JSON and ECMAscript" to explain some
155 incompatibilities between the two (problem was noted by
156 various people).
157 - add t/20_faihu.t.
158
1592.231 Thu Nov 20 04:59:08 CET 2008
160 - work around 5.10.0 magic bugs where manipulating magic values
161 (such as $1) would permanently damage them as perl would
162 ignore the magicalness, by making a full copy of the string,
163 reported by Dmitry Karasik.
164 - work around spurious warnings under older perl 5.8's.
165
1662.23 Mon Sep 29 05:08:29 CEST 2008
167 - fix a compilation problem when perl is not using char * as, well,
168 char *.
169 - use PL_hexdigit in favour of rolling our own.
170
1712.2222 Sun Jul 20 18:49:00 CEST 2008
172 - same game again, broken 5.10 finds yet another assertion
173 failure, and the workaround causes additional runtime warnings.
174 Work around the next assertion AND the warning. 5.10 seriously
175 needs to adjust it's attitude against working code.
176
1772.222 Sat Jul 19 06:15:34 CEST 2008
178 - you work around one -DDEBUGGING assertion bug in perl 5.10
179 just to hit the next one. work around this one, too.
180
1812.22 Tue Jul 15 13:26:51 CEST 2008
182 - allow higher nesting levels in incremental parser.
183 - error out earlier in some cases in the incremental parser
184 (as suggested by Yuval Kogman).
185 - improve incr-parser test (Yuval Kogman).
186
1872.21 Tue Jun 3 08:43:23 CEST 2008
188 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
189 - remove the experimental status of the incremental parser interface.
190 - move =encoding around again, to avoid bugs with search.cpan.org.
191 when can we finally have utf-8 in pod???
192 - add ->incr_reset method.
193
1942.2 Wed Apr 16 20:37:25 CEST 2008
195 - lifted the log2 rounding restriction of max_depth and max_size.
196 - make booleans mutable by creating a copy instead of handing out
197 the same scalar (reported by pasha sadri).
198 - added support for incremental json parsing (still EXPERIMENTAL).
199 - implemented and added a json_xs command line utility that can convert
200 from/to a number of serialisation formats - tell me if you need more.
201 - implement allow_unknown/get_allow_unknown methods.
202 - fixed documentation of max_depth w.r.t. higher and equal.
203 - moved down =encoding directive a bit, too much breaks if it's the first
204 pod directive :/.
205 - removed documentation section on other modules, it became somewhat
206 outdated and is nowadays mostly of historical interest.
207
2082.1 Wed Mar 19 23:23:18 CET 2008
209 - update documentation here and there: add a large section
210 about utf8/latin1/ascii flags, add a security consideration
211 and extend and clarify the JSON and YAML section.
212 - medium speed enhancements when encoding/decoding non-ascii chars.
213 - minor speedup in number encoding case.
214 - extend and clarify the section on incompatibilities
215 between YAML and JSON.
216 - switch to static inline from just inline when using gcc.
217 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
218 - fix some issues with UV to JSON conversion of unknown impact.
219 - published the yahoo locals search result used in benchmarks as the
220 original url changes so comparison is impossible.
221
2222.01 Wed Dec 5 11:40:28 CET 2007
223 - INCOMPATIBLE API CHANGE: to_json and from_json have been
224 renamed to encode_json/decode_json for JSON.pm compatibility.
225 The old functions croak and might be replaced by JSON.pm
226 comaptible versions in some later release.
227
2282.0 Tue Dec 4 11:30:46 CET 2007
229 - this is supposed to be the first version of JSON::XS
230 compatible with version 2.0+ of the JSON module.
231 Using the JSON module as frontend to JSON::XS should be
232 as fast as using JSON::XS directly, so consider using it
233 instead.
234 - added get_* methods for all "simple" options.
235 - make JSON::XS subclassable.
236
2371.53 Tue Nov 13 23:58:33 CET 2007
238 - minor doc clarifications.
239 - fixed many doc typos (patch by Thomas L. Shinnick).
240
2411.52 Mon Oct 15 03:22:06 CEST 2007
242 - remove =encoding pod directive again, it confuses too many pod
243 parsers :/.
244
2451.51 Sat Oct 13 03:55:56 CEST 2007
246 - encode empty arrays/hashes in a compact way when pretty is enabled.
247 - apparently JSON::XS was used to find some bugs in the
248 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
249 the testsuite.
250 - quite a bit of doc updates/extension.
251 - require 5.8.2, as this seems to be the first unicode-stable version.
252
2531.5 Tue Aug 28 04:05:38 CEST 2007
254 - add support for tied hashes, based on ideas and testcase by
255 Marcus Holland-Moritz.
256 - implemented relaxed parsing mode where some extensions are being
257 accepted. generation is still JSON-only.
258
2591.44 Wed Aug 22 01:02:44 CEST 2007
260 - very experimental process-emulation support, slowing everything down.
261 the horribly broken perl threads are still not supported - YMMV.
262
2631.43 Thu Jul 26 13:26:37 CEST 2007
264 - convert big json numbers exclusively consisting of digits to NV
265 only when there is no loss of precision, otherwise to string.
266
2671.42 Tue Jul 24 00:51:18 CEST 2007
268 - fix a crash caused by not handling missing array elements
269 (report and testcase by Jay Kuri).
270
2711.41 Tue Jul 10 18:21:44 CEST 2007
272 - fix compilation with NDEBUG (assert side-effect),
273 affects convert_blessed only.
274 - fix a bug in decode filters calling ENTER; SAVETMPS;
275 one time too often.
276 - catch a typical error in TO_JSON methods.
277 - antique-ised XS.xs again to work with outdated
278 C compilers (windows...).
279
2801.4 Mon Jul 2 10:06:30 CEST 2007
281 - add convert_blessed setting.
282 - encode did not catch all blessed objects, encoding their
283 contents in most cases. This has been fixed by introducing
284 the allow_blessed setting.
285 - added filter_json_object and filter_json_single_key_object
286 settings that specify a callback to be called when
287 all/specific json objects are encountered.
288 - assume that most object keys are simple ascii words and
289 optimise this case, penalising the general case. This can
290 speed up decoding by 30% in typical cases and gives
291 a smaller and faster perl hash.
292 - implemented simpleminded, optional resource size checking
293 in decode_json.
294 - remove objToJson/jsonToObj aliases, as the next version
295 of JSON will not have them either.
296 - bit the bullet and converted the very simple json object
297 into a more complex one.
298 - work around a bug where perl wrongly claims an integer
299 is not an integer.
300 - unbundle JSON::XS::Boolean into own pm file so Storable
301 and similar modules can resolve the overloading when thawing.
302
3031.3 Sun Jun 24 01:55:02 CEST 2007
304 - make JSON::XS::true and false special overloaded objects
305 and return those instead of 1 and 0 for those json atoms
306 (JSON::PP compatibility is NOT achieved yet).
307 - add JSON::XS::is_bool predicate to test for those special
308 values.
309 - add a reference to
310 http://jpsykes.com/47/practical-csrf-and-json-security.
311 - removed require 5.8.8 again, it is just not very expert-friendly.
312 Also try to be more compatible with slightly older versions,
313 which are not recommended (because they are buggy).
314
3151.24 Mon Jun 11 05:40:49 CEST 2007
316 - added informative section on JSON-as-YAML.
317 - get rid of some c99-isms again.
318 - localise dec->cur in decode_str, speeding up
319 string decoding considerably (>15% on my amd64 + gcc).
320 - increased SHORT_STRING_LEN to 16kb: stack space is
321 usually plenty, and this actually saves memory
322 when !shrinking as short strings will fit perfectly.
323
3241.23 Wed Jun 6 20:13:06 CEST 2007
325 - greatly improved small integer encoding and decoding speed.
326 - implement a number of µ-optimisations.
327 - updated benchmarks.
328
3291.22 Thu May 24 00:07:25 CEST 2007
330 - require 5.8.8 explicitly as older perls do not seem to offer
331 the required macros.
332 - possibly made it compile on so-called C compilers by microsoft.
333
3341.21 Wed May 9 18:40:32 CEST 2007
335 - character offset reported for trailing garbage was random.
336
3371.2 Wed May 9 18:35:01 CEST 2007
338 - decode did not work with magical scalars (doh!).
339 - added latin1 flag to produce JSON texts in the latin1 subset
340 of unicode.
341 - flag trailing garbage as error.
342 - new decode_prefix method that returns the number
343 of characters consumed by a decode.
344 - max octets/char in perls UTF-X is actually 13, not 11,
345 as pointed out by Glenn Linderman.
346 - fixed typoe reported by YAMASHINA Hio.
347
3481.11 Mon Apr 9 07:05:49 CEST 2007
349 - properly 0-terminate sv's returned by encode to help
350 C libraries that expect that 0 to be there.
351 - partially "port" JSON from C to microsofts fucking broken
352 pseudo-C. They should be burned to the ground for pissing
353 on standards. And I should be stoned for even trying to
354 support this filthy excuse for a c compiler.
355
3561.1 Wed Apr 4 01:45:00 CEST 2007
357 - clarify documentation (pointed out by Quinn Weaver).
358 - decode_utf8 sometimes did not correctly flag errors,
359 leading to segfaults.
360 - further reduced default nesting depth to 512 due to the test
361 failure by that anonymous "chris" whose e-mail address seems
362 to be impossible to get. Tests on other freebsd systems indicate
363 that this is likely a problem in his/her configuration and not this
364 module.
365 - renamed json => JSON in error messages.
366 - corrected the character offset in some error messages.
367
3681.01 Sat Mar 31 16:15:40 CEST 2007
369 - do not segfault when from_json/decode gets passed
370 a non-string object (reported by Florian Ragwitz).
371 This has no effect on normal operation.
372
3731.0 Thu Mar 29 04:43:34 CEST 2007
374 - the long awaited (by me) 1.0 version.
375 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
376 true and false.
377 - add some more notes to shrink, as suggested by Alex Efros.
378 - improve testsuite.
379 - halve the default nesting depth limit, to hopefully make it
380 work on Freebsd (unfortunately, the cpan tester did not
381 send me his report, so I cannot ask about the stack limit on fbsd).
382
3830.8 Mon Mar 26 00:10:48 CEST 2007
7 - fix a memleak when decoding hashes. 384 - fix a memleak when decoding hashes.
8 - export jsonToBj and objToJson as aliases 385 - export jsonToBj and objToJson as aliases
9 to to_json and from_json, to reduce incompatibilities 386 to to_json and from_json, to reduce incompatibilities
10 between JSON/JSON::PC and JSON::XS. (experimental). 387 between JSON/JSON::PC and JSON::XS. (experimental).
11 - implement a maximum nesting depth for both en- and de-coding. 388 - implement a maximum nesting depth for both en- and de-coding.
56 case the called functions do... stuff. 433 case the called functions do... stuff.
57 - croak when encoding to ascii and an out-of-range 434 - croak when encoding to ascii and an out-of-range
58 (non-unicode) codepoint is encountered. 435 (non-unicode) codepoint is encountered.

600.2 Fri Mar 23 00:23:34 CET 2007 4370.2 Fri Mar 23 00:23:34 CET 2007
61 - the "could not sleep without debuggign release". 438 - the "could not sleep without debugging release".
62 it should basically work now, with many bugs as 439 it should basically work now, with many bugs as
63 no production tests have been run yet. 440 no production tests have been run yet.
64 - added more testcases. 441 - added more testcases.
65 - the expected shitload of bugfixes. 442 - the expected shitload of bugfixes.
