File size: 35880 byte(s)
* gig.h, gig.cpp: Added File::GetRiffFile() method.
* DLS.h, DLS.cpp: Added File::GetRiffFile() method.
* sf2.h, sf2.cpp: Added Sample::GetFile() and
  File::GetRiffFile() methods.

  progress_t::subdivide() method which allows a more
  fine graded control into which portions the subtasks

1 schoenebeck 3392 Version SVN trunk (?)
2    
3 schoenebeck 3476 * general changes:
4     - Added MSVC build support (anonymous patch from mailing list).
5     - Introduced CMake build support (yet constrained for building with MSVC)
6     (anonymous patch from mailing list).
7 schoenebeck 3478 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
8     destructors. Added new virtual method DeleteChunks() to those classes
9     for this which must be explicitly called instead to remove their RIFF
10     chunks.
11     - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
12     of zero; which is unsafe per se.
13     - Added C++11 "override" keyword where appropriate.
14 schoenebeck 3476
15 schoenebeck 3398 * src/gig.cpp, src/gig.h:
16     - Fixed Doxygen API comments for enum types (currently latest Doxygen
17     [v1.8.13] only supports C comments in macro arguments expansion, but
18     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
19     the Doxygen source code, which currently also filter out new line
20     \n chars).
21 schoenebeck 3414 - Added new method File::CountSamples().
22     - Added new method File::CountInstruments().
23 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
24     (patch by Ivan Maguidhir).
25     - Added gig v4 version identifier (File::VERSION_4).
26 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
27     DimensionRegion::SustainReleaseTrigger which allows to define whether
28     a sustain pedal up event shall cause a release trigger sample to be
29     played (default: don't play release trigger sample by sustain pedal).
30 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
31     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
32     regular behaviour of playing release trigger sample on MIDI note-off
33     events.
34 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
35     (original patch by Ivan Maguidhir).
36 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).
37 schoenebeck 3481 - Added File::GetRiffFile() method.
38 schoenebeck 3398
39 schoenebeck 3463 * src/DLS.cpp, src/DLS.h:
40     - File: Fixed implicitly allocated RIFF::File object never been freed.
41 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
42     the respective classes for implementing (the old) UpdateChunks() and the
43     new DeleteChunks() method.
44 schoenebeck 3481 - Added File::GetRiffFile() method.
45 schoenebeck 3463
46 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
47     - Added Sample::GetFile() method.
48     - Added File::GetRiffFile() method.
49    
50 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:

52     compiler warnings when building and linking against the public API.
53 persson 3454 - Fixed comparision logic bug
54 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
55 schoenebeck 3392
56 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
57     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
58     caused a resource leak
59 persson 3468 - Avoid compiler warning when building for 32 bit windows.
60 schoenebeck 3478 - Added new method progress_t::subdivide().
61 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
62     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
63     allows a more fine graded control into which portions the subtasks are
64     divided to.
65 schoenebeck 3412
66 schoenebeck 3425 * src/tools/gigdump.cpp:
67     - Added command line option --instrument-names which causes only
68     instrument names and their index numbers to be printed.
69

75 schoenebeck 3048 - fixed various spelling mistakes (patch by Debian maintainer)
76 schoenebeck 3138 - Added new "Serialization" framework (and equally named namespace)
77     which allows to serialize and deserialize native C++ objects
78     in a portable, easy and flexible way.
79 schoenebeck 3173 - print compiler warning if no RTTI available
80 schoenebeck 3175 - Fixed potential crash in command line tools gig2stereo, korg2gig,
81     korgdump and sf2extract.
82 schoenebeck 3348 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
83     (original patch by Paul Brossier, slightly modified).

91 schoenebeck 2912 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
92 schoenebeck 2913 as one single monolithic gig file. In case .gig file is >= 2GB expect a
93     large monolithic file, otherwise if .gig file is < 2 GB check for
94     "extension" files (.gx01, .gx02, ...) instead.
95 schoenebeck 2923 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
96     if there were dimensions after the velocity dimension: it only created
97     valid velocity tables for cases of dimensions lower than the velocity
98     dimension.
99 schoenebeck 2985 - added new method Sample::VerifyWaveData() which allows to check whether
100     a sample had been damaged for some reason
101     - Fix: samples' CRC checksums were damaged on file structure changes.
102 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
103     - Added new method Sample::GetWaveDataCRC32Checksum().
104 schoenebeck 2990 - Changed default value of EG2Release (filter release time) to 60s.
105 schoenebeck 3112 - Instruments' default pitch bend range is now +-2 semi tones.
106 schoenebeck 3115 - Fixed CRC checksums being wrong sometimes.
107 schoenebeck 3117 - Fix: method File::AddContentOf() did not clone script groups and scripts
108     of passed original file.
109 schoenebeck 3138 - Added support for serializing & deserializing DimensionRegion
110     objects (and crossfade_t and leverage_ctrl_t objects).
111 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
112 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
113 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
114     textual format specifiers like with printf().
115     - On unknown leverage controller exception: show precise unknown leverage
116     controller number found.
117 schoenebeck 3203 - Ignore invalid leverage controller types and just show a warning on the
118     console instead of throwing an exception.
119 schoenebeck 3323 - Added new struct eg_opt_t and new class member variable
120 schoenebeck 3327 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
121     extension to the gig file format, which allows to override the default
122     behavior of the first two EGs' state machines.
123 schoenebeck 3349 - Fixed undefined behavior when loading a gig file with invalid
124     velocity curve parameters (fixes CVE-2017-12951).
125 schoenebeck 3350 - Fixed undefined behavior when loading a gig file with invalid wave
126     pool index number (fixes CVE-2017-12954).
127 schoenebeck 2909
128 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
129     - Sample: wave pool offsets are now 64 bits (to allow support for files
130     larger than 4 GB).
131 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
132     textual format specifiers like with printf().
133 persson 3454
134 schoenebeck 2912 * src/RIFF.cpp, src/RIFF.h:
135     - added support for RIFF files larger than 4 GB, by default the required
136     internal RIFF file offset size is automatically detected (that is RIFF
137     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
138     automatically use 64 bit offsets), a particular offset size can be forced
139     with a new option added to the RIFF File constructor though
140     - when saving a modified, grown RIFF file, the temporary file size during
141     Save() operation will no longer be larger than the final grown file size
142 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
143     textual format specifiers like with printf().

154     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
155 schoenebeck 3153 - Object: Added method memberByUID().
156     - Object: remove() method is now protected.
157 schoenebeck 3156 - Archive: Added method removeMember().
158     - Archive: Added methods name() and setName().
159     - Archive: Added methods comment() and setComment().
160     - Archive: Added methods timeStampCreated(), timeStampModified(),
161     dateTimeCreated() and dateTimeModified().
162 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
163 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
164     asLongDescr() and customTypeName(bool demangle=false)).
165 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
166     representations like "yes", "no", "true", "false" as expected.
167 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
168     textual format specifiers like with printf().

189     the raw wave form data integrity of all samples
190     - added and implemented new parameter "--rebuild-checksums" which allows
191     to recalculate the CRC32 checksum of all samples' raw wave data and
192     rebuilding the gig file's global checksum table (i.e. in case the
193     file's checksum table was damaged)

712     - version of shared library can be set in configure.in
713    
714 schoenebeck 58 Version 0.7.0 (3 May 2004)
715    
716     * general changes:
717     - various big endian specific corrections
718     (successfully tested now on PPC)
719     - minor adjustments to avoid compile errors on some systems
720     (using now pow() instead of powl() and --pedantic g++ compiler switch)
721     - libtoolized the library
722     - added man pages for the command line tools
723     (gigextract, gigdump, dlsdump, rifftree)
724    
725     * src/gig.cpp, src/gig.h:
726     - fixed bug in decompression algorithm which caused it not to detect
727     the end of a stream
728     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
729     takes the MIDI key velocity value as an argument and returns the
730     appropriate volume factor (0.0 ... 1.0) for the sample to be played
731     back, the velocity curve transformation functions used for this are
732     only an approximation so far
733     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
734     'Sample::LoopSize' which reflected wrong values
735     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
736     measured in sample points instead of byte offset
737     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
738     'Sample::FineTune'
739     - added class attribute 'Sample::LoopSize'
740     - added method GetInstrument(uint index) to class 'File'
741     - added ReadAndLoop() method to class 'Sample' which is an extension to
742     the normal Read() method to honor the sample's looping information
743     while streaming from disk
744     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
745     'eg2_ctrl_t': replaced this huge enumeration by a structure which
746     reflects the MIDI controller number in case of an ordinary control
747     change controller (this saves a huge switch-case block in the
748     application of the library user)
749     - renamed following attributes in class 'DimensionRegion':
750     'AttenuationContol' -> 'AttenuationController',
751     'InvertAttenuationControl' -> 'InvertAttenuationController',
752     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
753     - minor fix in API documentation for method GetVelocityAttenuation() in
754     class 'DimensionRegion'
755    
756     * src/RIFF.cpp, src/RIFF.h:
757     - added additional API documentation
758     - minor fix in Chunk::Read() method (only a minor efficiency issue)
759    
760     * src/gigdump.cpp:
761     - added printout of samples' looping informations
762    
763 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
