1 root 1.1 Revision history for Perl extension JSON::XS
2 root 1.2
3 root 1.147 TODO: maybe detetc and croak on more invalid inputs (e.g. +-inf/nan)
4 root 1.151 TODO: maybe avoid the reblessing and better support readonly objects.
5 root 1.153 TODO: http://stevehanov.ca/blog/index.php?id=104 compression
6 root 1.151
7 root 1.156 - remove to_json/from_json.
8    
9 root 1.155 2.34 Thu May 23 11:30:34 CEST 2013
10     - work around bugs in perl 5.18 breaking more than 100
11     widely used modules, without a fix in sight because
12     p5pers don't care about CPAN anymore.
13 root 1.154 - when canonicalising, only allocate up to 64 hash key
14     pointers on the stack. for larger hashes, use the heap,
15     to avoid using too much stackspace.
16 root 1.155 - discuss the problem with setlocale (reported by a few victims).
17 root 1.154
18 root 1.153 2.33 Wed Aug 1 21:03:52 CEST 2012
19     - internal encode/decode XS wrappers did not expect stack
20     moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
21 root 1.151 - add bencode as to/from option in bin/json_xs.
22 root 1.152 - add -e option to json_xs, and none and string in/out formats.
23 root 1.147
24 root 1.150 2.32 Thu Aug 11 19:06:38 CEST 2011
25     - fix a bug in the initial whitespace accumulation.
26    
27 root 1.149 2.31 Wed Jul 27 17:53:05 CEST 2011
28 root 1.153 - don't accumulate initial whitespace in the incremental buffer
29 root 1.149 (this can be useful to allow whitespace-keepalive on a tcp
30     connection without triggering the max_size limit).
31 root 1.148 - properly croak on some invalid inputs that are not strings
32     (e.g. undef) when trying to decode a json text (reported
33     and analyzed by Goro Fuji).
34    
35 root 1.146 2.3 Wed Aug 18 01:26:47 CEST 2010
36     - make sure decoder doesn't change the decoding in the incremental
37     parser (testcase provided by Hendrik Schumacher).
38 root 1.144 - applied patch by DaTa for Data::Dumper support in json_xs.
39 root 1.145 - added -t dump support to json_xs, using Data::Dump.
40 root 1.146 - added -f eval support to json_xs.
41 root 1.144
42 root 1.143 2.29 Wed Mar 17 02:39:12 CET 2010
43     - fix a memory leak when callbacks set using filter_json_object
44     or filter_json_single_key_object were called (great testcase
45     by Eric Wilhelm).
46    
47 root 1.142 2.28 Thu Mar 11 20:30:46 CET 2010
48 root 1.139 - implement our own atof function - perl's can be orders of
49     magnitudes slower than even the system one. on the positive
50     side, ours seems to be more exact in general than perl's.
51     (testcase provided by Tim Meadowcroft).
52 root 1.142 - clarify floating point conversion issues a bit.
53 root 1.138 - update jpsykes csrf article url.
54 root 1.140 - updated benchmark section - JSON::PP became much faster!
55 root 1.138
56 root 1.137 2.27 Thu Jan 7 07:35:08 CET 2010
57 root 1.136 - support relaxed option inside the incremental parser
58 root 1.137 (testcase provided by IKEGAMI via Makamaka).
59 root 1.136
60 root 1.135 2.26 Sat Oct 10 03:26:19 CEST 2009
61     - big integers could become truncated (based on patch
62     by Strobl Anton).
63 root 1.134 - output format change: indent now adds a final newline, which is
64     more expected and more true to the documentation.
65 root 1.132
66 root 1.131 2.25 Sat Aug 8 12:04:41 CEST 2009
67     - the perl debugger completely breaks lvalue subs - try to work
68     around the issue.
69 root 1.130 - ignore RMAGICAL hashes w.r.t. CANONICAL.
70 root 1.128 - try to work around a possible char signedness issue on aix.
71 root 1.129 - require common sense.
72 root 1.128
73 root 1.127 2.24 Sat May 30 08:25:45 CEST 2009
74     - the incremental parser did not update its parse offset
75     pointer correctly when parsing utf8-strings (nicely
76     debugged by Martin Evans).
77     - appending a non-utf8-string to the incremental parser
78     in utf8 mode failed to upgrade the string.
79     - wording of parse error messages has been improved.
80    
81 root 1.126 2.232 Sun Feb 22 11:12:25 CET 2009
82 root 1.125 - use an exponential algorithm to extend strings, to
83 root 1.126 help platforms with bad or abysmal==windows memory
84     allocater performance, at the expense of some memory
85 root 1.125 wastage (use shrink to recover this extra memory).
86     (nicely analysed by Dmitry Karasik).
87    
88 root 1.124 2.2311 Thu Feb 19 02:12:54 CET 2009
89 root 1.123 - add a section "JSON and ECMAscript" to explain some
90     incompatibilities between the two (problem was noted by
91     various people).
92 root 1.122 - add t/20_faihu.t.
93    
94 root 1.121 2.231 Thu Nov 20 04:59:08 CET 2008
95     - work around 5.10.0 magic bugs where manipulating magic values
96     (such as $1) would permanently damage them as perl would
97     ignore the magicalness, by making a full copy of the string,
98     reported by Dmitry Karasik.
99 root 1.125 - work around spurious warnings under older perl 5.8's.
100 root 1.121
101 root 1.120 2.23 Mon Sep 29 05:08:29 CEST 2008
102     - fix a compilation problem when perl is not using char * as, well,
103     char *.
104 root 1.119 - use PL_hexdigit in favour of rolling our own.
105    
106 root 1.118 2.2222 Sun Jul 20 18:49:00 CEST 2008
107     - same game again, broken 5.10 finds yet another assertion
108     failure, and the workaround causes additional runtime warnings.
109     Work around the next assertion AND the warning. 5.10 seriously
110     needs to adjust it's attitude against working code.
111    
112 root 1.117 2.222 Sat Jul 19 06:15:34 CEST 2008
113     - you work around one -DDEBUGGING assertion bug in perl 5.10
114     just to hit the next one. work around this one, too.
115    
116 root 1.116 2.22 Tue Jul 15 13:26:51 CEST 2008
117 root 1.115 - allow higher nesting levels in incremental parser.
118     - error out earlier in some cases in the incremental parser
119     (as suggested by Yuval Kogman).
120     - improve incr-parser test (Yuval Kogman).
121    
122 root 1.114 2.21 Tue Jun 3 08:43:23 CEST 2008
123     - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
124 root 1.112 - remove the experimental status of the incremental parser interface.
125 root 1.111 - move =encoding around again, to avoid bugs with search.cpan.org.
126     when can we finally have utf-8 in pod???
127 root 1.113 - add ->incr_reset method.
128 root 1.111
129 root 1.110 2.2 Wed Apr 16 20:37:25 CEST 2008
130 root 1.109 - lifted the log2 rounding restriction of max_depth and max_size.
131 root 1.107 - make booleans mutable by creating a copy instead of handing out
132     the same scalar (reported by pasha sadri).
133 root 1.105 - added support for incremental json parsing (still EXPERIMENTAL).
134 root 1.103 - implemented and added a json_xs command line utility that can convert
135     from/to a number of serialisation formats - tell me if you need more.
136 root 1.108 - implement allow_unknown/get_allow_unknown methods.
137 root 1.109 - fixed documentation of max_depth w.r.t. higher and equal.
138 root 1.112 - moved down =encoding directive a bit, too much breaks if it's the first
139 root 1.102 pod directive :/.
140 root 1.106 - removed documentation section on other modules, it became somewhat
141     outdated and is nowadays mostly of historical interest.
142 root 1.102
143 root 1.101 2.1 Wed Mar 19 23:23:18 CET 2008
144     - update documentation here and there: add a large section
145     about utf8/latin1/ascii flags, add a security consideration
146     and extend and clarify the JSON and YAML section.
147 root 1.98 - medium speed enhancements when encoding/decoding non-ascii chars.
148 root 1.100 - minor speedup in number encoding case.
149 root 1.92 - extend and clarify the section on incompatibilities
150     between YAML and JSON.
151 root 1.95 - switch to static inline from just inline when using gcc.
152 root 1.94 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
153 root 1.100 - fix some issues with UV to JSON conversion of unknown impact.
154 root 1.99 - published the yahoo locals search result used in benchmarks as the
155     original url changes so comparison is impossible.
156 root 1.92
157 root 1.91 2.01 Wed Dec 5 11:40:28 CET 2007
158     - INCOMPATIBLE API CHANGE: to_json and from_json have been
159     renamed to encode_json/decode_json for JSON.pm compatibility.
160     The old functions croak and might be replaced by JSON.pm
161     comaptible versions in some later release.
162    
163 root 1.90 2.0 Tue Dec 4 11:30:46 CET 2007
164     - this is supposed to be the first version of JSON::XS
165     compatible with version 2.0+ of the JSON module.
166     Using the JSON module as frontend to JSON::XS should be
167     as fast as using JSON::XS directly, so consider using it
168     instead.
169 root 1.88 - added get_* methods for all "simple" options.
170 root 1.89 - make JSON::XS subclassable.
171 root 1.88
172 root 1.86 1.53 Tue Nov 13 23:58:33 CET 2007
173 root 1.85 - minor doc clarifications.
174     - fixed many doc typos (patch by Thomas L. Shinnick).
175    
176 root 1.84 1.52 Mon Oct 15 03:22:06 CEST 2007
177 root 1.83 - remove =encoding pod directive again, it confuses too many pod
178     parsers :/.
179    
180 root 1.82 1.51 Sat Oct 13 03:55:56 CEST 2007
181 root 1.81 - encode empty arrays/hashes in a compact way when pretty is enabled.
182 root 1.87 - apparently JSON::XS was used to find some bugs in the
183 root 1.80 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
184     the testsuite.
185     - quite a bit of doc updates/extension.
186 root 1.79 - require 5.8.2, as this seems to be the first unicode-stable version.
187 root 1.78
188 root 1.77 1.5 Tue Aug 28 04:05:38 CEST 2007
189 root 1.74 - add support for tied hashes, based on ideas and testcase by
190     Marcus Holland-Moritz.
191 root 1.75 - implemented relaxed parsing mode where some extensions are being
192     accepted. generation is still JSON-only.
193 root 1.74
194     1.44 Wed Aug 22 01:02:44 CEST 2007
195 root 1.73 - very experimental process-emulation support, slowing everything down.
196     the horribly broken perl threads are still not supported - YMMV.
197    
198 root 1.72 1.43 Thu Jul 26 13:26:37 CEST 2007
199     - convert big json numbers exclusively consisting of digits to NV
200     only when there is no loss of precision, otherwise to string.
201    
202 root 1.71 1.42 Tue Jul 24 00:51:18 CEST 2007
203     - fix a crash caused by not handling missing array elements
204     (report and testcase by Jay Kuri).
205    
206 root 1.70 1.41 Tue Jul 10 18:21:44 CEST 2007
207     - fix compilation with NDEBUG (assert side-effect),
208     affects convert_blessed only.
209 root 1.69 - fix a bug in decode filters calling ENTER; SAVETMPS;
210     one time too often.
211 root 1.70 - catch a typical error in TO_JSON methods.
212 root 1.69 - antique-ised XS.xs again to work with outdated
213     C compilers (windows...).
214    
215 root 1.68 1.4 Mon Jul 2 10:06:30 CEST 2007
216 root 1.63 - add convert_blessed setting.
217 root 1.56 - encode did not catch all blessed objects, encoding their
218     contents in most cases. This has been fixed by introducing
219     the allow_blessed setting.
220 root 1.65 - added filter_json_object and filter_json_single_key_object
221     settings that specify a callback to be called when
222 root 1.67 all/specific json objects are encountered.
223 root 1.59 - assume that most object keys are simple ascii words and
224     optimise this case, penalising the general case. This can
225     speed up decoding by 30% in typical cases and gives
226     a smaller and faster perl hash.
227 root 1.58 - implemented simpleminded, optional resource size checking
228     in decode_json.
229 root 1.61 - remove objToJson/jsonToObj aliases, as the next version
230     of JSON will not have them either.
231 root 1.62 - bit the bullet and converted the very simple json object
232     into a more complex one.
233 root 1.64 - work around a bug where perl wrongly claims an integer
234     is not an integer.
235 root 1.65 - unbundle JSON::XS::Boolean into own pm file so Storable
236     and similar modules can resolve the overloading when thawing.
237 root 1.56
238 root 1.55 1.3 Sun Jun 24 01:55:02 CEST 2007
239 root 1.54 - make JSON::XS::true and false special overloaded objects
240     and return those instead of 1 and 0 for those json atoms
241     (JSON::PP compatibility is NOT achieved yet).
242     - add JSON::XS::is_bool predicate to test for those special
243     values.
244 root 1.52 - add a reference to
245     http://jpsykes.com/47/practical-csrf-and-json-security.
246 root 1.60 - removed require 5.8.8 again, it is just not very expert-friendly.
247     Also try to be more compatible with slightly older versions,
248 root 1.54 which are not recommended (because they are buggy).
249 root 1.52
250 root 1.51 1.24 Mon Jun 11 05:40:49 CEST 2007
251 root 1.49 - added informative section on JSON-as-YAML.
252 root 1.51 - get rid of some c99-isms again.
253 root 1.50 - localise dec->cur in decode_str, speeding up
254     string decoding considerably (>15% on my amd64 + gcc).
255     - increased SHORT_STRING_LEN to 16kb: stack space is
256     usually plenty, and this actually saves memory
257 root 1.51 when !shrinking as short strings will fit perfectly.
258 root 1.49
259 root 1.47 1.23 Wed Jun 6 20:13:06 CEST 2007
260 root 1.46 - greatly improved small integer encoding and decoding speed.
261     - implement a number of µ-optimisations.
262 root 1.47 - updated benchmarks.
263 root 1.46
264 root 1.45 1.22 Thu May 24 00:07:25 CEST 2007
265 root 1.42 - require 5.8.8 explicitly as older perls do not seem to offer
266     the required macros.
267 root 1.43 - possibly made it compile on so-called C compilers by microsoft.
268 root 1.42
269 root 1.41 1.21 Wed May 9 18:40:32 CEST 2007
270 root 1.47 - character offset reported for trailing garbage was random.
271 root 1.41
272 root 1.40 1.2 Wed May 9 18:35:01 CEST 2007
273     - decode did not work with magical scalars (doh!).
274 root 1.38 - added latin1 flag to produce JSON texts in the latin1 subset
275     of unicode.
276 root 1.39 - flag trailing garbage as error.
277     - new decode_prefix method that returns the number
278     of characters consumed by a decode.
279 root 1.40 - max octets/char in perls UTF-X is actually 13, not 11,
280     as pointed out by Glenn Linderman.
281     - fixed typoe reported by YAMASHINA Hio.
282 root 1.34
283 root 1.32 1.11 Mon Apr 9 07:05:49 CEST 2007
284     - properly 0-terminate sv's returned by encode to help
285     C libraries that expect that 0 to be there.
286 root 1.31 - partially "port" JSON from C to microsofts fucking broken
287     pseudo-C. They should be burned to the ground for pissing
288     on standards. And I should be stoned for even trying to
289 root 1.32 support this filthy excuse for a c compiler.
290 root 1.6
291 root 1.30 1.1 Wed Apr 4 01:45:00 CEST 2007
292 root 1.28 - clarify documentation (pointed out by Quinn Weaver).
293 root 1.29 - decode_utf8 sometimes did not correctly flag errors,
294     leading to segfaults.
295 root 1.30 - further reduced default nesting depth to 512 due to the test
296     failure by that anonymous "chris" whose e-mail address seems
297     to be impossible to get. Tests on other freebsd systems indicate
298     that this is likely a problem in his/her configuration and not this
299     module.
300     - renamed json => JSON in error messages.
301     - corrected the character offset in some error messages.
302 root 1.28
303 root 1.27 1.01 Sat Mar 31 16:15:40 CEST 2007
304     - do not segfault when from_json/decode gets passed
305     a non-string object (reported by Florian Ragwitz).
306     This has no effect on normal operation.
307    
308 root 1.25 1.0 Thu Mar 29 04:43:34 CEST 2007
309     - the long awaited (by me) 1.0 version.
310     - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
311     true and false.
312 root 1.24 - add some more notes to shrink, as suggested by Alex Efros.
313 root 1.25 - improve testsuite.
314 root 1.26 - halve the default nesting depth limit, to hopefully make it
315 root 1.25 work on Freebsd (unfortunately, the cpan tester did not
316     send me his report, so I cannot ask about the stack limit on fbsd).
317 root 1.24
318 root 1.23 0.8 Mon Mar 26 00:10:48 CEST 2007
319 root 1.21 - fix a memleak when decoding hashes.
320 root 1.20 - export jsonToBj and objToJson as aliases
321     to to_json and from_json, to reduce incompatibilities
322     between JSON/JSON::PC and JSON::XS. (experimental).
323 root 1.21 - implement a maximum nesting depth for both en- and de-coding.
324     - added a security considerations sections.
325 root 1.20
326 root 1.19 0.7 Sun Mar 25 01:46:30 CET 2007
327 root 1.16 - code cleanup.
328     - fix a memory overflow bug when indenting.
329     - pretty-printing now up to 15% faster.
330     - improve decoding speed of strings by
331     up to 50% by specialcasing short strings.
332     - further decoding speedups for strings using
333     lots of \u escapes.
334 root 1.17 - improve utf8 decoding speed for U+80 .. U+7FF.
335 root 1.16
336 root 1.15 0.5 Sat Mar 24 20:41:51 CET 2007
337 root 1.14 - added the UTF-16 encoding example hinted at in previous
338     versions.
339     - minor documentation fixes.
340 root 1.15 - fix a bug in and optimise canonicalising fastpath
341     (reported by Craig Manley).
342     - remove a subtest that breaks with bleadperl (reported
343     by Andreas König).
344 root 1.14
345 root 1.13 0.31 Sat Mar 24 02:14:34 CET 2007
346 root 1.12 - documentation updates.
347 root 1.13 - do some casting to hopefully fix Andreas' problem.
348     - nuke bogus json rpc stuff.
349 root 1.12
350 root 1.11 0.3 Fri Mar 23 19:33:21 CET 2007
351 root 1.5 - remove spurious PApp::Util reference (John McNamara).
352     - adapted lots of tests from other json modules
353     (idea by Chris Carline).
354 root 1.9 - documented mapping from json to perl and vice versa.
355 root 1.11 - improved the documentation by adding more examples.
356 root 1.5 - added short escaping forms, reducing the created
357     json texts a bit.
358     - added shrink flag.
359     - when flag methods are called without enable argument
360     they will by default enable their flag.
361     - considerably improved string encoding speed (at least
362     with gcc 4).
363 root 1.7 - added a test that covers lots of different characters.
364     - clarified some error messages.
365     - error messages now use correct character offset
366     with F_UTF8.
367 root 1.8 - improve the "no bytes" and "no warnings" hacks in
368     case the called functions do... stuff.
369 root 1.9 - croak when encoding to ascii and an out-of-range
370     (non-unicode) codepoint is encountered.
371 root 1.4
372 root 1.3 0.2 Fri Mar 23 00:23:34 CET 2007
373 root 1.109 - the "could not sleep without debugging release".
374 root 1.3 it should basically work now, with many bugs as
375     no production tests have been run yet.
376     - added more testcases.
377     - the expected shitload of bugfixes.
