GIG FORMAT EXTENSION: Introducing support for 'patch' script variables.

* gig.cpp/.h: Added 5 new API methods to class gig::Instrument:
  IsScriptPatchVariableSet(), GetScriptPatchVariables(),
  GetScriptPatchVariable(), SetScriptPatchVariable(),
  UnsetScriptPatchVariable().

* gig.cpp: Store/restore values for those 'patch' variables persistently
  to/from a separate new 'SCPV' RIFF chunk as child of our own '3LS '
  RIFF list chunk (which we use for our own gig format extensions on
  Instrument level).

* Bumped version (4.2.0.svn8).


1 schoenebeck 3623 Version SVN trunk (?)
2    
3     * general changes:
4     - Require at least a C++11 compliant compiler.
5 schoenebeck 3723 - Require some UUID generating function by underlying system.
6 schoenebeck 3623
7     * src/gig.cpp, src/gig.h:
8     - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1WaveForm,
9     DimensionRegion::LFO2WaveForm and DimensionRegion::LFO3WaveForm, which
10     allow to define override LFOs' wave form (e.g. saw or square instead of
11     the default wave form which was always sine in the original
12     Gigasampler/GigaStudio software).
13     - GIG FORMAT EXTENSION: Added attributes DimensionRegion::LFO1Phase,
14     DimensionRegion::LFO2Phase and DimensionRegion::LFO3Phase, which allow to
15     move the start point horizontally of the LFOs' waves (0° ... 360°).
16     - GIG FORMAT EXTENSION: Added attribute DimensionRegion::LFO3FlipPhase
17     (the original Gigasampler/GigaStudio software only had that flip phase
18     option for LFO1 and LFO2).
19 schoenebeck 3710 - Added methods DimensionRegion::UsesAnyGigFormatExtension(),
20     Region::UsesAnyGigFormatExtension(),
21     Instrument::UsesAnyGigFormatExtension() and
22     File::UsesAnyGigFormatExtension() (however only as private methods yet,
23     see comments on methods why).
24 schoenebeck 3645 - GIG FORMAT EXTENSION: added LinuxSampler specific filter type
25     implementations to enum vcf_type_t: vcf_type_lowpass_1p,
26     vcf_type_lowpass_2p, vcf_type_lowpass_4p, vcf_type_lowpass_6p,
27     vcf_type_highpass_1p, vcf_type_highpass_2p, vcf_type_highpass_4p,
28     vcf_type_highpass_6p, vcf_type_bandpass_2p, vcf_type_bandreject_2p.
29 schoenebeck 3656 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
30     (patch by Ivan Maguidhir).
31 schoenebeck 3657 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
32     (original patch by Ivan Maguidhir).
33 schoenebeck 3720 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
34     dimensions being in different order after deleting a dimension zone.
35 schoenebeck 3723 - Script: Generate a persistent UUID for each script.
36 schoenebeck 3731 - GIG FORMAT EXTENSION: Added support for script 'patch' variables and
37     accordingly added new methods to Instrument class:
38     IsScriptPatchVariableSet(), GetScriptPatchVariables(),
39     GetScriptPatchVariable(), SetScriptPatchVariable(),
40     UnsetScriptPatchVariable(); stored persistently as new 'SCPV' RIFF chunk
41     as child of our '3LS ' list chunk on Instrument level.
42 schoenebeck 3623
43     * src/tools/gigdump.cpp:
44     - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
45     LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
46     LFO2FlipPhase and LFO3FlipPhase.
47    
48 schoenebeck 3524 Version 4.2.0 (25 Jul 2019)
49 schoenebeck 3392
50 schoenebeck 3476 * general changes:
51     - Added MSVC build support (anonymous patch from mailing list).
52     - Introduced CMake build support (yet constrained for building with MSVC)
53     (anonymous patch from mailing list).
54 schoenebeck 3478 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
55     destructors. Added new virtual method DeleteChunks() to those classes
56     for this which must be explicitly called instead to remove their RIFF
57     chunks.
58     - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
59     of zero; which is unsafe per se.
60     - Added C++11 "override" keyword where appropriate.
61 schoenebeck 3488 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
62     of their actions when not passing a progress_t callback structure.
63 schoenebeck 3476
64 schoenebeck 3398 * src/gig.cpp, src/gig.h:
65     - Fixed Doxygen API comments for enum types (currently latest Doxygen
66     [v1.8.13] only supports C comments in macro arguments expansion, but
67     not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
68     the Doxygen source code, which currently also filter out new line
69     \n chars).
70 schoenebeck 3414 - Added new method File::CountSamples().
71     - Added new method File::CountInstruments().
72 schoenebeck 3440 - Fixed gig v4 files falsely being handled as v2 format
73     (patch by Ivan Maguidhir).
74     - Added gig v4 version identifier (File::VERSION_4).
75 schoenebeck 3442 - GIG FORMAT EXTENSION: Added attribute
76     DimensionRegion::SustainReleaseTrigger which allows to define whether
77     a sustain pedal up event shall cause a release trigger sample to be
78     played (default: don't play release trigger sample by sustain pedal).
79 schoenebeck 3447 - GIG FORMAT EXTENSION: Added attribute
80     DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
81     regular behaviour of playing release trigger sample on MIDI note-off
82     events.
83 schoenebeck 3474 - Introduced support for writing extension files (.gx01, .gx02, ...)
84     (original patch by Ivan Maguidhir).
85 schoenebeck 3478 - Many gig classes derive now from DLS::Storage (see DLS changes below).
86 schoenebeck 3481 - Added File::GetRiffFile() method.
87 schoenebeck 3398
88 schoenebeck 3463 * src/DLS.cpp, src/DLS.h:
89     - File: Fixed implicitly allocated RIFF::File object never been freed.
90 schoenebeck 3478 - Added new abstract interface base class DLS::Storage which is derived by
91     the respective classes for implementing (the old) UpdateChunks() and the
92     new DeleteChunks() method.
93 schoenebeck 3481 - Added File::GetRiffFile() method.
94 schoenebeck 3463
95 schoenebeck 3481 * src/sf2.cpp, src/sf2.h:
96     - Added Sample::GetFile() method.
97     - Added File::GetRiffFile() method.
98    
99 schoenebeck 3392 * src/Serialization.cpp, src/Serialization.h:
100     - Hide pure internal declarations from header file to avoid numerous
101     compiler warnings when building and linking against the public API.
102 persson 3454 - Fixed comparision logic bug
103 schoenebeck 3464 - Fixed memory leak in DataType::customTypeName().
104 schoenebeck 3392
105 schoenebeck 3412 * src/RIFF.cpp, src/RIFF.h:
106     - Fix: Calling File::SetMode() left an undefined file handle on Windows and
107     caused a resource leak
108 persson 3468 - Avoid compiler warning when building for 32 bit windows.
109 schoenebeck 3478 - Added new method progress_t::subdivide().
110 schoenebeck 3481 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
111     - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
112     allows a more fine graded control into which portions the subtasks are
113     divided to.
114 schoenebeck 3412
115 schoenebeck 3425 * src/tools/gigdump.cpp:
116     - Added command line option --instrument-names which causes only
117     instrument names and their index numbers to be printed.
118

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

141 schoenebeck 2913 as one single monolithic gig file. In case .gig file is >= 2GB expect a
142     large monolithic file, otherwise if .gig file is < 2 GB check for
143     "extension" files (.gx01, .gx02, ...) instead.
144 schoenebeck 2923 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
145     if there were dimensions after the velocity dimension: it only created
146     valid velocity tables for cases of dimensions lower than the velocity
147     dimension.
148 schoenebeck 2985 - added new method Sample::VerifyWaveData() which allows to check whether
149     a sample had been damaged for some reason
150     - Fix: samples' CRC checksums were damaged on file structure changes.
151 schoenebeck 2989 - Fix: samples' CRC checksums were misordered when a Sample was deleted.

159     objects (and crossfade_t and leverage_ctrl_t objects).
160 schoenebeck 3169 - Added enum reflection API functions for retrieving enum declaration type
161 schoenebeck 3181 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
162 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
163     textual format specifiers like with printf().
164     - On unknown leverage controller exception: show precise unknown leverage
165     controller number found.
166 schoenebeck 3203 - Ignore invalid leverage controller types and just show a warning on the
167     console instead of throwing an exception.
168 schoenebeck 3323 - Added new struct eg_opt_t and new class member variable
169 schoenebeck 3327 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
170     extension to the gig file format, which allows to override the default
171     behavior of the first two EGs' state machines.
172 schoenebeck 3349 - Fixed undefined behavior when loading a gig file with invalid
173     velocity curve parameters (fixes CVE-2017-12951).
174 schoenebeck 3350 - Fixed undefined behavior when loading a gig file with invalid wave
175     pool index number (fixes CVE-2017-12954).
176 schoenebeck 2909
177 schoenebeck 2912 * src/DLS.cpp, src/DLS.h:
178     - Sample: wave pool offsets are now 64 bits (to allow support for files
179     larger than 4 GB).
180 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
181     textual format specifiers like with printf().
182 persson 3454
183 schoenebeck 2912 * src/RIFF.cpp, src/RIFF.h:
184     - added support for RIFF files larger than 4 GB, by default the required
185     internal RIFF file offset size is automatically detected (that is RIFF
186     files < 4 GB automatically use 32 bit offsets while files >= 4 GB
187     automatically use 64 bit offsets), a particular offset size can be forced
188     with a new option added to the RIFF File constructor though
189     - when saving a modified, grown RIFF file, the temporary file size during
190     Save() operation will no longer be larger than the final grown file size
191 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
192     textual format specifiers like with printf().

203     archive had been modified (i.e. by remove(), setAutoValue(), etc.).
204 schoenebeck 3153 - Object: Added method memberByUID().
205     - Object: remove() method is now protected.
206 schoenebeck 3156 - Archive: Added method removeMember().
207     - Archive: Added methods name() and setName().
208     - Archive: Added methods comment() and setComment().
209     - Archive: Added methods timeStampCreated(), timeStampModified(),
210     dateTimeCreated() and dateTimeModified().
211 schoenebeck 3169 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
212 schoenebeck 3173 - DataType: Implemented demangling C++ type names (for methods
213     asLongDescr() and customTypeName(bool demangle=false)).
214 schoenebeck 3185 - Archive::setAutoValue(): Handle human readable boolean text
215     representations like "yes", "no", "true", "false" as expected.
216 schoenebeck 3198 - Exception class now has a variadic constructor which allows to add
217     textual format specifiers like with printf().

232 schoenebeck 2923 * src/tools/gigdump.cpp:
233     - additionally print VelocityUpperLimit and DimensionUpperLimits of all
234     dimension regions
235 schoenebeck 2984 - additionally print RIFF chunk file offset and RIFF chunk size of sample
236     data
237 schoenebeck 2985 - added and implemented new parameter "--verify" which allows to check
238     the raw wave form data integrity of all samples
239     - added and implemented new parameter "--rebuild-checksums" which allows
240     to recalculate the CRC32 checksum of all samples' raw wave data and
241     rebuilding the gig file's global checksum table (i.e. in case the
242     file's checksum table was damaged)
243 schoenebeck 2989 - print samples' CRC32 checksums

769     (using now pow() instead of powl() and --pedantic g++ compiler switch)
770     - libtoolized the library
771     - added man pages for the command line tools
772     (gigextract, gigdump, dlsdump, rifftree)
773    
774     * src/gig.cpp, src/gig.h:
775     - fixed bug in decompression algorithm which caused it not to detect
776     the end of a stream
777     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
778     takes the MIDI key velocity value as an argument and returns the
779     appropriate volume factor (0.0 ... 1.0) for the sample to be played
780     back, the velocity curve transformation functions used for this are
781     only an approximation so far
782     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
783     'Sample::LoopSize' which reflected wrong values
784     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
785     measured in sample points instead of byte offset
786     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
787     'Sample::FineTune'
788     - added class attribute 'Sample::LoopSize'
789     - added method GetInstrument(uint index) to class 'File'
790     - added ReadAndLoop() method to class 'Sample' which is an extension to
791     the normal Read() method to honor the sample's looping information
792     while streaming from disk
793     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
794     'eg2_ctrl_t': replaced this huge enumeration by a structure which
795     reflects the MIDI controller number in case of an ordinary control
796     change controller (this saves a huge switch-case block in the
797     application of the library user)
798     - renamed following attributes in class 'DimensionRegion':
799     'AttenuationContol' -> 'AttenuationController',
800     'InvertAttenuationControl' -> 'InvertAttenuationController',
801     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
802     - minor fix in API documentation for method GetVelocityAttenuation() in
803     class 'DimensionRegion'
804    
805     * src/RIFF.cpp, src/RIFF.h:
806     - added additional API documentation
807     - minor fix in Chunk::Read() method (only a minor efficiency issue)
808    
809     * src/gigdump.cpp:
810     - added printout of samples' looping informations
