* Preparations for new release (libgig 4.2.0).

1 schoenebeck 3524 Version 4.2.0 (25 Jul 2019)
2 schoenebeck 3392
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 3488 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
15     of their actions when not passing a progress_t callback structure.
16 schoenebeck 3476
17 schoenebeck 3398 * src/gig.cpp, src/gig.h:
18     - Fixed Doxygen API comments for enum types (currently latest Doxygen
19     [v1.8.13] only supports C comments in macro arguments expansion, but
20     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
21     the Doxygen source code, which currently also filter out new line
22     \n chars).
23 schoenebeck 3414 - Added new method File::CountSamples().
24     - Added new method File::CountInstruments().
25 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
26     (patch by Ivan Maguidhir).
27     - Added gig v4 version identifier (File::VERSION_4).
28 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
29     DimensionRegion::SustainReleaseTrigger which allows to define whether
30     a sustain pedal up event shall cause a release trigger sample to be
31     played (default: don't play release trigger sample by sustain pedal).
32 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
33     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
34     regular behaviour of playing release trigger sample on MIDI note-off
35     events.
36 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
37     (original patch by Ivan Maguidhir).
38 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).
39 schoenebeck 3481 - Added File::GetRiffFile() method.
40 schoenebeck 3398
41 schoenebeck 3463 * src/DLS.cpp, src/DLS.h:
42     - File: Fixed implicitly allocated RIFF::File object never been freed.
43 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
44     the respective classes for implementing (the old) UpdateChunks() and the
45     new DeleteChunks() method.
46 schoenebeck 3481 - Added File::GetRiffFile() method.
47 schoenebeck 3463
48 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
49     - Added Sample::GetFile() method.
50     - Added File::GetRiffFile() method.
51    
52 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:
53     - Hide pure internal declarations from header file to avoid numerous
54     compiler warnings when building and linking against the public API.
55 persson 3454 - Fixed comparision logic bug
56 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
57 schoenebeck 3392
58 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
59     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
60     caused a resource leak
61 persson 3468 - Avoid compiler warning when building for 32 bit windows.
62 schoenebeck 3478 - Added new method progress_t::subdivide().
63 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
64     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
65     allows a more fine graded control into which portions the subtasks are
66     divided to.
67 schoenebeck 3412
68 schoenebeck 3425 * src/tools/gigdump.cpp:
69     - Added command line option --instrument-names which causes only
70     instrument names and their index numbers to be printed.
71

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

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

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

190 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
191     the raw wave form data integrity of all samples
192     - added and implemented new parameter "--rebuild-checksums" which allows
193     to recalculate the CRC32 checksum of all samples' raw wave data and
194     rebuilding the gig file's global checksum table (i.e. in case the
195     file's checksum table was damaged)

719     - various big endian specific corrections
720     (successfully tested now on PPC)
721     - minor adjustments to avoid compile errors on some systems
722     (using now pow() instead of powl() and --pedantic g++ compiler switch)
723     - libtoolized the library
724     - added man pages for the command line tools
725     (gigextract, gigdump, dlsdump, rifftree)
726    
727     * src/gig.cpp, src/gig.h:
728     - fixed bug in decompression algorithm which caused it not to detect
729     the end of a stream
730     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
731     takes the MIDI key velocity value as an argument and returns the
732     appropriate volume factor (0.0 ... 1.0) for the sample to be played
733     back, the velocity curve transformation functions used for this are
734     only an approximation so far
735     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
736     'Sample::LoopSize' which reflected wrong values
737     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
738     measured in sample points instead of byte offset
739     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
740     'Sample::FineTune'
741     - added class attribute 'Sample::LoopSize'
742     - added method GetInstrument(uint index) to class 'File'
743     - added ReadAndLoop() method to class 'Sample' which is an extension to
744     the normal Read() method to honor the sample's looping information
745     while streaming from disk
746     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
747     'eg2_ctrl_t': replaced this huge enumeration by a structure which
748     reflects the MIDI controller number in case of an ordinary control
749     change controller (this saves a huge switch-case block in the
750     application of the library user)
751     - renamed following attributes in class 'DimensionRegion':
752     'AttenuationContol' -> 'AttenuationController',
753     'InvertAttenuationControl' -> 'InvertAttenuationController',
754     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
755     - minor fix in API documentation for method GetVelocityAttenuation() in
756     class 'DimensionRegion'
757    
758     * src/RIFF.cpp, src/RIFF.h:
759     - added additional API documentation
760     - minor fix in Chunk::Read() method (only a minor efficiency issue)
761    
762     * src/gigdump.cpp:
763     - added printout of samples' looping informations
764    
765 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
