- \0, \1, \undef do not work, and were not intended to ever work, as |
| 15 |
special values, despite being mentioned in the documentation (reported |
| 16 |
by nuclightq). |
| 17 |
|
| 18 |
1.86 Thu 04 Nov 2021 17:48:16 CET |
| 19 |
- fixed a wrong printf format specifier (reported by Petr Písař). |
| 20 |
|
| 21 |
1.85 Sat 23 Oct 2021 04:59:56 CEST |
| 22 |
- left debugging printf in code, need a test for that :( |
| 23 |
|
| 24 |
1.84 Thu 21 Oct 2021 03:11:52 CEST |
| 25 |
- fix a bug in validate_utf8 where we call perl's is_utf8_string with |
| 26 |
a lenght of zero for empty strings, but perl interprets that as |
| 27 |
"calculate length", causing spurious validation errors for |
| 28 |
empty strings. |
| 29 |
- include validate_utf8 in new_safe. |
| 30 |
- avoid some warnings. |
| 31 |
|
| 32 |
1.83 Tue Dec 8 09:27:06 CET 2020 |
| 33 |
- add CBOR::XS::as_map cast function. |
| 34 |
|
| 35 |
1.82 Tue Dec 1 02:47:40 CET 2020 |
| 36 |
- add CBOR::XS::as_bool cast function. |
| 37 |
|
| 38 |
1.81 Mon Nov 30 19:29:33 CET 2020 |
| 39 |
- cast functions were broken due to last-minute renaming. thats |
| 40 |
what you get for not having a tessuite. |
| 41 |
- Math::BigInt and Math::BigFloat are pretty broken (again), |
| 42 |
so disable some tests. (try printing the bigfloat |
| 43 |
799999999999999999998E99999999999999999998). |
| 44 |
|
| 45 |
1.8 Sun Nov 29 22:35:13 CET 2020 |
| 46 |
- experimental support for some type casts, as well as embedding |
| 47 |
raw cbor data. |
| 48 |
|
| 49 |
1.71 Thu Nov 15 20:52:13 CET 2018 |
| 50 |
- work around what smells like a perl bug w.r.t. exceptions |
| 51 |
thrown in callbacks. |
| 52 |
- update libecb. |
| 53 |
|
| 54 |
1.7 Tue Jun 27 04:02:23 CEST 2017 |
| 55 |
- SECURITY FIX: fix two bugs found by american fuzzy lop, |
| 56 |
upgrade is advised if you accept data from untrusted |
| 57 |
sources. |
| 58 |
- an out-of bound sharedref or stringref index could cause an |
| 59 |
out of bounds access - might be exploitable. |
| 60 |
- a decoding error during indefinite array or hash decoding |
| 61 |
could cause an endless loop. |
| 62 |
|
| 63 |
1.6 Wed Dec 7 15:13:23 CET 2016 |
| 64 |
- greatly expand the SECURITY IMPLICATIONS and similar sections. |
| 65 |
- new constructor new_safe, to create a secure CBOR::XS object. |
| 66 |
- new option forbid_objects, to disallow serialisation. |
| 67 |
- new CBOR::XS::safe_filter functionality. |
| 68 |
- fix a crash when decoding a cyclic data structure using |
| 69 |
stringref/pack_strings when allow_cycles is disabled. |
| 70 |
- fix a crash when decoding hash keys with length >= 2**31. |
| 71 |
- avoid unreasonably long decoding times for certain |
| 72 |
types of (corrupt) cbor texts. |
| 73 |
- support arrays and hashes with >= 2**31 members. |
| 74 |
- avoid overflow on pointer arithmetic when checking whether enough |
| 75 |
data is available. |
| 76 |
- fix a memory leak that occured when decoding failed while decoding |
| 77 |
a tagged value. |
| 78 |
- do not leak the partially constructed result when stringifying |
| 79 |
a hash key throws an exception. |
| 80 |
- various code size and efficiency optimizations (reduced code |
| 81 |
from 42 to 40kB on my system, despite the new features). |
| 82 |
|
| 83 |
1.5 Wed Apr 27 11:38:39 CEST 2016 |
| 84 |
- Math::BigFloat madness workaround, see |
| 85 |
http://blog.schmorp.de/2016-04-23-mathbigfloat-maintainer-fail.html |
| 86 |
(bugreport by zdm@softvisio.net). |
| 87 |
- add text_keys and text_strings options to force CBOR text encoding |
| 88 |
for perl hash keys or all strings, as a result of discussions |
| 89 |
with Fredrik Ljunggren. |
| 90 |
- implement support for arbitrary-exponent numbers (see |
| 91 |
http://peteroupc.github.io/CBOR/bigfrac.html, tags 264 and 265) |
| 92 |
for both en- and decoding. |
| 93 |
- implement support for rational numbers (see |
| 94 |
http://peteroupc.github.io/CBOR/rational.html, tag 30) for both |
| 95 |
en- and decoding. |
| 96 |
- the above effectively implements all registered CBOR extensions |
| 97 |
in a sensible manner. |
| 98 |
- remove some weird dead code that was duplicated (%FILTER). |
| 99 |
- add t/58_hv.t, which tests hashes and the new text_* flags. |
| 100 |
hashes apparently were not encoded at all in any of the existing |
| 101 |
tests. |
| 102 |
- document Math::BigFloat base-2 performance/crash issues. |
| 103 |
- use stability canary. |
| 104 |
|
| 105 |
1.41 Thu 25 Feb 15:22:03 CET 2016 |
| 106 |
- avoid perl panics on nested FREEZE/THAW calls (testcase by |
| 107 |
Victor Efimov). |
| 108 |
|
| 109 |
1.4 Mon Feb 8 05:10:15 CET 2016 |
| 110 |
- buffer overflow fix: a fast path during decoding did not check |
| 111 |
remaining length when decoding hash keys, found by fuzzing. |
| 112 |
This can potentially leak information in the error message |
| 113 |
or crash the process. |
| 114 |
- use C style { 0 } struct initializer. |
| 115 |
- upgrade libecb. |
| 116 |
|
| 117 |
1.3 Mon Apr 27 22:21:04 CEST 2015 |
| 118 |
- the incremental parser didn't properly parse tagged values |
| 119 |
(testcase by Mons Anderson). |
| 120 |
- slightly speed up encoding of plain (nonmagical) arrays. |
| 121 |
- try to clarify further that effectively all 32 bit architectures |
| 122 |
have 64 bit integer support. |
| 123 |
- upgrade libecb. |
| 124 |
|
| 125 |
1.26 Sat Oct 25 08:35:44 CEST 2014 |
| 126 |
- update the t/57_incr.t subtest that would rely on 64 bit ints. |
| 127 |
- disable t/50_rfc.t test that fails because of broken data::dumper. |
| 128 |
|
| 129 |
1.25 Sun Jan 5 15:19:14 CET 2014 |
| 130 |
- map key decoding was pretty much botched due to the recent cleanups. |
| 131 |
- work around Time::Piece->epoch returning a string value, avoid encoding |
| 132 |
this as a tag 1 string. |
| 133 |
- enable more testcases in t/50_rfc.t, now that they work :) |
| 134 |
|
| 135 |
1.2 Tue Dec 10 22:06:42 CET 2013 |
| 136 |
- implement an incremental decoder. |
| 137 |
|
| 138 |
1.12 Tue Dec 3 11:23:22 CET 2013 |
| 139 |
- work around broken Time::Piece (in old versions of the module, %z doesn't |
| 140 |
work as documented, gives different results on different platforms(!)). |
| 141 |
|
| 142 |
1.11 Sun Dec 1 18:00:00 CET 2013 |
| 143 |
- new setting: validate_utf8, for when you can't trust your cbor data. |
| 144 |
- do not leak memory on decoding errors, when allow_cycles is enabled. |
| 145 |
- add default filters for tags 0 and 1, using Time::Piece. |
| 146 |
- more tests added. |
| 147 |
|
| 148 |
1.1 Sat Nov 30 19:14:27 CET 2013 |
| 149 |
- INCOMPATIBLE CHANGE: new decoder setting: allow_cyclic, needed to decode |
| 150 |
cyclic data structures (to avoid memleaks in unsuspecting code). |
| 151 |
- no longer "share" references that aren't, i.e. true/false/null/error/tagged. |
| 152 |
- fix stringref w.r.t. indefinite-length strings. |
| 153 |
- verify indefinite-length string chunk types. |
| 154 |
- do not allow extremely large arrays - assume an array element |
| 155 |
requires at least one CBOR byte, to avoid memory exhaustion attacks. |
| 156 |
- major code overhaul. |
| 157 |
|
| 158 |
1.0 Thu Nov 28 16:43:31 CET 2013 |
| 159 |
- use the now official tag values for extensions. remove the |
| 160 |
experimental notice. it's the real thing now, with real bugs. |
| 161 |
- renamed allow_stringref to pack_strings. |
| 162 |
- port to perl <= 5.16. |
| 163 |
- slightly improve the documentation. |
| 164 |
|
| 165 |

| 166 |
- bignum/bigfloat/decimal support. |
| 167 |
- uri support. |
| 168 |
- tag filter functions support for decoding. |
| 169 |
- do not support reference-to-1/0/undef anymore, you need to use |
| 170 |
the Types::Serialiser objects now. |
| 171 |
- experimental sharable extension support (http://cbor.schmorp.de/value-sharing). |
| 172 |
- experimental stringref extension support (http://cbor.schmorp.de/stringref). |
| 173 |
- implement indirection tag (http://cbor.schmorp.de/indirection). |
| 174 |
|
| 175 |
0.08 Wed Oct 30 11:10:43 CET 2013 |
| 176 |
- defused another too fragile test. |
| 177 |
|
| 178 |
0.07 Tue Oct 29 23:04:07 CET 2013 |
| 179 |
- don't crash in decode when silly values are passed in. |
| 180 |
- considerably speed up map decoding when map keys |
| 181 |
are utf-8 or byte strings. |
| 182 |
- raising an exception in THAW should now work without |
| 183 |
leaking. |
| 184 |
|
| 185 |
0.06 Tue Oct 29 16:56:07 CET 2013 |
| 186 |
- do not leak when deserialiasing via THAW. |

| 194 |
- implement TO_CBOR/FREEZE/THAW serialisation protocols. |
| 195 |
- requested perl-object and generic-object tags from iana. |
| 196 |
- switched to Types::Serialiser for true, false and error. |
| 197 |
- disabled some fragile tests (thanks, andk). |
| 198 |
|
| 199 |
0.03 Sun Oct 27 00:28:41 CEST 2013 |
| 200 |
- improve 32 bit platform compatibility. |
| 201 |
- take more advantage of ecb.h. |

- preliminary tagged decoding to arrayref. |
| 209 |
- indefinite encoding fixed. |
| 210 |
- half float decoding implemented. |
