File size: 32308 byte(s)
* src/gig.cpp: Fixed undefined behavior when loading a gig file with
  invalid wave pool index number (fixes CVE-2017-12954).
* Bumped version (4.0.0.svn33).

1 persson 2836 Version SVN trunk
2 schoenebeck 2909 * general changes:
3 schoenebeck 2912 - removed 2 GB limitation when loading a gig or DLS file
4 schoenebeck 2922 - using now native integer size where appropriate
5 schoenebeck 3047 - fixed minor issues with man pages (patch by Debian maintainer)
6 schoenebeck 3048 - fixed various spelling mistakes (patch by Debian maintainer)
7 schoenebeck 3138 - Added new "Serialization" framework (and equally named namespace)
8     which allows to serialize and deserialize native C++ objects
9     in a portable, easy and flexible way.
10 schoenebeck 3173 - print compiler warning if no RTTI available
11 schoenebeck 3175 - Fixed potential crash in command line tools gig2stereo, korg2gig,
12     korgdump and sf2extract.
13 schoenebeck 3348 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
14     (original patch by Paul Brossier, slightly modified).
15 schoenebeck 2909
16 schoenebeck 2912 * src/gig.cpp, src/gig.h:
17 persson 2836 - fixed bug in Script::SetGroup: the script chunk wasn't moved
18     - fixed compilation error with clang 3.4
19 schoenebeck 2912 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
20 schoenebeck 2913 as one single monolithic gig file. In case .gig file is >= 2GB expect a
21     large monolithic file, otherwise if .gig file is < 2 GB check for
22     "extension" files (.gx01, .gx02, ...) instead.
23 schoenebeck 2923 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
24     if there were dimensions after the velocity dimension: it only created
25     valid velocity tables for cases of dimensions lower than the velocity
26     dimension.
27 schoenebeck 2985 - added new method Sample::VerifyWaveData() which allows to check whether
28     a sample had been damaged for some reason
29     - Fix: samples' CRC checksums were damaged on file structure changes.
30 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
31     - Added new method Sample::GetWaveDataCRC32Checksum().
32 schoenebeck 2990 - Changed default value of EG2Release (filter release time) to 60s.
33 schoenebeck 3112 - Instruments' default pitch bend range is now +-2 semi tones.
34 schoenebeck 3115 - Fixed CRC checksums being wrong sometimes.
35 schoenebeck 3117 - Fix: method File::AddContentOf() did not clone script groups and scripts
36     of passed original file.
37 schoenebeck 3138 - Added support for serializing & deserializing DimensionRegion
38     objects (and crossfade_t and leverage_ctrl_t objects).
39 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
40 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
41 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
42     textual format specifiers like with printf().
43     - On unknown leverage controller exception: show precise unknown leverage
44     controller number found.
45 schoenebeck 3203 - Ignore invalid leverage controller types and just show a warning on the
46     console instead of throwing an exception.
47 schoenebeck 3323 - Added new struct eg_opt_t and new class member variable
48 schoenebeck 3327 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
49     extension to the gig file format, which allows to override the default
50     behavior of the first two EGs' state machines.
51 schoenebeck 3349 - Fixed undefined behavior when loading a gig file with invalid
52     velocity curve parameters (fixes CVE-2017-12951).
53 schoenebeck 3350 - Fixed undefined behavior when loading a gig file with invalid wave
54     pool index number (fixes CVE-2017-12954).
55 schoenebeck 2909
56 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
57     - Sample: wave pool offsets are now 64 bits (to allow support for files
58     larger than 4 GB).
59 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
60     textual format specifiers like with printf().
61 schoenebeck 2912
62     * src/RIFF.cpp, src/RIFF.h:
63     - added support for RIFF files larger than 4 GB, by default the required
64     internal RIFF file offset size is automatically detected (that is RIFF
65     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
66     automatically use 64 bit offsets), a particular offset size can be forced
67     with a new option added to the RIFF File constructor though
68     - when saving a modified, grown RIFF file, the temporary file size during
69     Save() operation will no longer be larger than the final grown file size
70 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
71     textual format specifiers like with printf().

81     - Archive::rawData(): Automatically re-encode new raw data stream if
82     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
83 schoenebeck 3153 - Object: Added method memberByUID().
84     - Object: remove() method is now protected.
85 schoenebeck 3156 - Archive: Added method removeMember().
86     - Archive: Added methods name() and setName().
87     - Archive: Added methods comment() and setComment().
88     - Archive: Added methods timeStampCreated(), timeStampModified(),
89     dateTimeCreated() and dateTimeModified().
90 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
91 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
92     asLongDescr() and customTypeName(bool demangle=false)).
93 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
94     representations like "yes", "no", "true", "false" as expected.
95 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
96     textual format specifiers like with printf().
97 schoenebeck 3334 - DataType fix: Retain backward compatibility to older versions of native
98     C++ classes/structs.

639 schoenebeck 58 Version 0.7.0 (3 May 2004)
640    
641     * general changes:
642     - various big endian specific corrections
643     (successfully tested now on PPC)
644     - minor adjustments to avoid compile errors on some systems
645     (using now pow() instead of powl() and --pedantic g++ compiler switch)
646     - libtoolized the library
647     - added man pages for the command line tools
648     (gigextract, gigdump, dlsdump, rifftree)
649    
650     * src/gig.cpp, src/gig.h:
651     - fixed bug in decompression algorithm which caused it not to detect
652     the end of a stream
653     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
654     takes the MIDI key velocity value as an argument and returns the
655     appropriate volume factor (0.0 ... 1.0) for the sample to be played
656     back, the velocity curve transformation functions used for this are
657     only an approximation so far
658     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
659     'Sample::LoopSize' which reflected wrong values
660     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
661     measured in sample points instead of byte offset
662     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
663     'Sample::FineTune'
664     - added class attribute 'Sample::LoopSize'
665     - added method GetInstrument(uint index) to class 'File'
666     - added ReadAndLoop() method to class 'Sample' which is an extension to
667     the normal Read() method to honor the sample's looping information
668     while streaming from disk
669     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
670     'eg2_ctrl_t': replaced this huge enumeration by a structure which
671     reflects the MIDI controller number in case of an ordinary control
672     change controller (this saves a huge switch-case block in the
673     application of the library user)
674     - renamed following attributes in class 'DimensionRegion':
675     'AttenuationContol' -> 'AttenuationController',
676     'InvertAttenuationControl' -> 'InvertAttenuationController',
677     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
678     - minor fix in API documentation for method GetVelocityAttenuation() in
679     class 'DimensionRegion'
680    
681     * src/RIFF.cpp, src/RIFF.h:
682     - added additional API documentation
683     - minor fix in Chunk::Read() method (only a minor efficiency issue)
684    
685     * src/gigdump.cpp:
686     - added printout of samples' looping informations
687    
688 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
