* Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
  (original patch by Paul Brossier, slightly modified).
* Bumped version (4.0.0.svn31).

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 2909
52 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
53     - Sample: wave pool offsets are now 64 bits (to allow support for files
54     larger than 4 GB).
55 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
56     textual format specifiers like with printf().
57 schoenebeck 2912
58     * src/RIFF.cpp, src/RIFF.h:
59     - added support for RIFF files larger than 4 GB, by default the required
60     internal RIFF file offset size is automatically detected (that is RIFF
61     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
62     automatically use 64 bit offsets), a particular offset size can be forced
63     with a new option added to the RIFF File constructor though
64     - when saving a modified, grown RIFF file, the temporary file size during
65     Save() operation will no longer be larger than the final grown file size
66 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
67     textual format specifiers like with printf().
68 schoenebeck 2912

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

109 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
110     the raw wave form data integrity of all samples
111     - added and implemented new parameter "--rebuild-checksums" which allows
112     to recalculate the CRC32 checksum of all samples' raw wave data and
113     rebuilding the gig file's global checksum table (i.e. in case the
114     file's checksum table was damaged)

592     * packaging changes:
593     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

605 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
606     trigger dimension, no bit range check for dimensions of split type
607     'split_type_bit')

611 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
612 schoenebeck 231
613 schoenebeck 220 * src/gigextract.cpp:
614     - added support for libsndfile (if libaudiofile and libsndfile are

629     Redhat packages
630 capela 168 - header files included on installation.
631     - autotools-generated files removed from CVS repository.
632 schoenebeck 186 - added support for generating Debian packages
633     - version of shared library can be set in configure.in
634    
635 schoenebeck 58 Version 0.7.0 (3 May 2004)
636    
637     * general changes:
638     - various big endian specific corrections
639     (successfully tested now on PPC)
640     - minor adjustments to avoid compile errors on some systems
641     (using now pow() instead of powl() and --pedantic g++ compiler switch)
642     - libtoolized the library
643     - added man pages for the command line tools
644     (gigextract, gigdump, dlsdump, rifftree)
645    
646     * src/gig.cpp, src/gig.h:
647     - fixed bug in decompression algorithm which caused it not to detect
648     the end of a stream
649     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
650     takes the MIDI key velocity value as an argument and returns the
651     appropriate volume factor (0.0 ... 1.0) for the sample to be played
652     back, the velocity curve transformation functions used for this are
653     only an approximation so far
654     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
655     'Sample::LoopSize' which reflected wrong values
656     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
657     measured in sample points instead of byte offset
658     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
659     'Sample::FineTune'
660     - added class attribute 'Sample::LoopSize'
661     - added method GetInstrument(uint index) to class 'File'
662     - added ReadAndLoop() method to class 'Sample' which is an extension to
663     the normal Read() method to honor the sample's looping information
664     while streaming from disk
665     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
666     'eg2_ctrl_t': replaced this huge enumeration by a structure which
667     reflects the MIDI controller number in case of an ordinary control
668     change controller (this saves a huge switch-case block in the
669     application of the library user)
670     - renamed following attributes in class 'DimensionRegion':
671     'AttenuationContol' -> 'AttenuationController',
672     'InvertAttenuationControl' -> 'InvertAttenuationController',
673     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
674     - minor fix in API documentation for method GetVelocityAttenuation() in
675     class 'DimensionRegion'
676    
677     * src/RIFF.cpp, src/RIFF.h:
678     - added additional API documentation
679     - minor fix in Chunk::Read() method (only a minor efficiency issue)
680    
681     * src/gigdump.cpp:
682     - added printout of samples' looping informations
683    
684 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
685    
686     * initial release
