Serialization.cpp/.h: Added built-in support for C++ Array<> objects

* Introduced out of the box support for serialising / deserialising
  variables of C++ Array<> data types (a.k.a. std::vector from the STL).

* Member offsets are now signed and for (newly added support of) member
  variables on the heap -1 is always used as offset instead.

* Bumped version (4.2.0.svn13).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Require at least a C++11 compliant compiler.
5 - Require some UUID generating function by underlying system.
6
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 - 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 - 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 - Compatibility fix: GigaStudio always expects 128 '3gnm' RIFF chunks
30 (patch by Ivan Maguidhir).
31 - Compatibility fix: GigaStudio 3 expects '3dnm' and '3ddp' RIFF chunks
32 (original patch by Ivan Maguidhir).
33 - Region::DeleteDimensionZone() and Region::SplitDimensionZone(): Fixed
34 dimensions being in different order after deleting a dimension zone.
35 - Script: Generate a persistent UUID for each script.
36 - 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
43 * src/Serialization.cpp, src/Serialization.h:
44 - Fixed broken Archive(RawData) constructor which always threw an
45 Exception.
46 - Added built-in support for C++ String objects (a.k.a. std::string
47 from the STL) and bumped Srx format version to 1.1 for that reason.
48 - Fixed assertion fault on some systems if a member variable defined was
49 serialized which was declared as size_t or ssize_t data type.
50 - Added new method Archive::operation() which allows applications to
51 distinguish between serialization vs. deserialization in their
52 serialize() method implementations.
53 - Added built-in support for C++ Array<> objects (a.k.a. std::vector from
54 the STL).
55 - Member offsets are now signed and for (newly added support of) member
56 variables on the heap -1 is always used as offset instead.
57
58 * src/tools/gigdump.cpp:
59 - Print dimension region properties LFO1WaveForm, LFO2WaveForm,
60 LFO3WaveForm, LFO1Phase, LFO2Phase, LFO3Phase, LFO1FlipPhase,
61 LFO2FlipPhase and LFO3FlipPhase.
62
63 Version 4.2.0 (25 Jul 2019)
64
65 * general changes:
66 - Added MSVC build support (anonymous patch from mailing list).
67 - Introduced CMake build support (yet constrained for building with MSVC)
68 (anonymous patch from mailing list).
69 - Fix: Don't automatically delete RIFF chunks from DLS/gig classes'
70 destructors. Added new virtual method DeleteChunks() to those classes
71 for this which must be explicitly called instead to remove their RIFF
72 chunks.
73 - Fix: Many methods of DLS/gig classes assumed a RIFF chunk read position
74 of zero; which is unsafe per se.
75 - Added C++11 "override" keyword where appropriate.
76 - Fixed crash in RIFF, DLS and gig classes which occurred on certain
77 of their actions when not passing a progress_t callback structure.
78
79 * src/gig.cpp, src/gig.h:
80 - Fixed Doxygen API comments for enum types (currently latest Doxygen
81 [v1.8.13] only supports C comments in macro arguments expansion, but
82 not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
83 the Doxygen source code, which currently also filter out new line
84 \n chars).
85 - Added new method File::CountSamples().
86 - Added new method File::CountInstruments().
87 - Fixed gig v4 files falsely being handled as v2 format
88 (patch by Ivan Maguidhir).
89 - Added gig v4 version identifier (File::VERSION_4).
90 - GIG FORMAT EXTENSION: Added attribute
91 DimensionRegion::SustainReleaseTrigger which allows to define whether
92 a sustain pedal up event shall cause a release trigger sample to be
93 played (default: don't play release trigger sample by sustain pedal).
94 - GIG FORMAT EXTENSION: Added attribute
95 DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
96 regular behaviour of playing release trigger sample on MIDI note-off
97 events.
98 - Introduced support for writing extension files (.gx01, .gx02, ...)
99 (original patch by Ivan Maguidhir).
100 - Many gig classes derive now from DLS::Storage (see DLS changes below).
101 - Added File::GetRiffFile() method.
102
103 * src/DLS.cpp, src/DLS.h:
104 - File: Fixed implicitly allocated RIFF::File object never been freed.
105 - Added new abstract interface base class DLS::Storage which is derived by
106 the respective classes for implementing (the old) UpdateChunks() and the
107 new DeleteChunks() method.
108 - Added File::GetRiffFile() method.
109
110 * src/sf2.cpp, src/sf2.h:
111 - Added Sample::GetFile() method.
112 - Added File::GetRiffFile() method.
113
114 * src/Serialization.cpp, src/Serialization.h:
115 - Hide pure internal declarations from header file to avoid numerous
116 compiler warnings when building and linking against the public API.
117 - Fixed comparision logic bug
118 - Fixed memory leak in DataType::customTypeName().
119
120 * src/RIFF.cpp, src/RIFF.h:
121 - Fix: Calling File::SetMode() left an undefined file handle on Windows and
122 caused a resource leak
123 - Avoid compiler warning when building for 32 bit windows.
124 - Added new method progress_t::subdivide().
125 - Fix: API doc comment for Chunk::GetFilePos() was completely wrong.
126 - progress_t: Added a 2nd (overridden) progress_t::subdivide() method which
127 allows a more fine graded control into which portions the subtasks are
128 divided to.
129
130 * src/tools/gigdump.cpp:
131 - Added command line option --instrument-names which causes only
132 instrument names and their index numbers to be printed.
133
134 Version 4.1.0 (25 Nov 2017)
135 * general changes:
136 - removed 2 GB limitation when loading a gig or DLS file
137 - using now native integer size where appropriate
138 - fixed minor issues with man pages (patch by Debian maintainer)
139 - fixed various spelling mistakes (patch by Debian maintainer)
140 - Added new "Serialization" framework (and equally named namespace)
141 which allows to serialize and deserialize native C++ objects
142 in a portable, easy and flexible way.
143 - print compiler warning if no RTTI available
144 - Fixed potential crash in command line tools gig2stereo, korg2gig,
145 korgdump and sf2extract.
146 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
147 (original patch by Paul Brossier, slightly modified).
148 - Debian: Fixed packaging error about invalid substitution variable
149 "Source-Version".
150 - Raised Debian compatibility level to Debian 9 "Stretch".
151
152 * src/gig.cpp, src/gig.h:
153 - fixed bug in Script::SetGroup: the script chunk wasn't moved
154 - fixed compilation error with clang 3.4
155 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
156 as one single monolithic gig file. In case .gig file is >= 2GB expect a
157 large monolithic file, otherwise if .gig file is < 2 GB check for
158 "extension" files (.gx01, .gx02, ...) instead.
159 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
160 if there were dimensions after the velocity dimension: it only created
161 valid velocity tables for cases of dimensions lower than the velocity
162 dimension.
163 - added new method Sample::VerifyWaveData() which allows to check whether
164 a sample had been damaged for some reason
165 - Fix: samples' CRC checksums were damaged on file structure changes.
166 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
167 - Added new method Sample::GetWaveDataCRC32Checksum().
168 - Changed default value of EG2Release (filter release time) to 60s.
169 - Instruments' default pitch bend range is now +-2 semi tones.
170 - Fixed CRC checksums being wrong sometimes.
171 - Fix: method File::AddContentOf() did not clone script groups and scripts
172 of passed original file.
173 - Added support for serializing & deserializing DimensionRegion
174 objects (and crossfade_t and leverage_ctrl_t objects).
175 - Added enum reflection API functions for retrieving enum declaration type
176 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
177 - Exception class now has a variadic constructor which allows to add
178 textual format specifiers like with printf().
179 - On unknown leverage controller exception: show precise unknown leverage
180 controller number found.
181 - Ignore invalid leverage controller types and just show a warning on the
182 console instead of throwing an exception.
183 - Added new struct eg_opt_t and new class member variable
184 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
185 extension to the gig file format, which allows to override the default
186 behavior of the first two EGs' state machines.
187 - Fixed undefined behavior when loading a gig file with invalid
188 velocity curve parameters (fixes CVE-2017-12951).
189 - Fixed undefined behavior when loading a gig file with invalid wave
190 pool index number (fixes CVE-2017-12954).
191
192 * src/DLS.cpp, src/DLS.h:
193 - Sample: wave pool offsets are now 64 bits (to allow support for files
194 larger than 4 GB).
195 - Exception class now has a variadic constructor which allows to add
196 textual format specifiers like with printf().
197
198 * src/RIFF.cpp, src/RIFF.h:
199 - added support for RIFF files larger than 4 GB, by default the required
200 internal RIFF file offset size is automatically detected (that is RIFF
201 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
202 automatically use 64 bit offsets), a particular offset size can be forced
203 with a new option added to the RIFF File constructor though
204 - when saving a modified, grown RIFF file, the temporary file size during
205 Save() operation will no longer be larger than the final grown file size
206 - Exception class now has a variadic constructor which allows to add
207 textual format specifiers like with printf().
208
209 * src/Serialization.cpp, src/Serialization.h:
210 - Archive: Added method isModified().
211 - Archive: Added method setAutoValue().
212 - Archive: Added method setIntValue().
213 - Archive: Added method setRealValue().
214 - Archive: Added method setBoolValue().
215 - Archive: Added method setEnumValue().
216 - Archive: Added method valueAsString().
217 - Archive::rawData(): Automatically re-encode new raw data stream if
218 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
219 - Object: Added method memberByUID().
220 - Object: remove() method is now protected.
221 - Archive: Added method removeMember().
222 - Archive: Added methods name() and setName().
223 - Archive: Added methods comment() and setComment().
224 - Archive: Added methods timeStampCreated(), timeStampModified(),
225 dateTimeCreated() and dateTimeModified().
226 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
227 - DataType: Implemented demangling C++ type names (for methods
228 asLongDescr() and customTypeName(bool demangle=false)).
229 - Archive::setAutoValue(): Handle human readable boolean text
230 representations like "yes", "no", "true", "false" as expected.
231 - Exception class now has a variadic constructor which allows to add
232 textual format specifiers like with printf().
233 - DataType fix: Retain backward compatibility to older versions of native
234 C++ classes/structs.
235
236 * src/Akai.cpp:
237 - Fixed compilation error with recent, more strict compilers.

251 data
252 - added and implemented new parameter "--verify" which allows to check
253 the raw wave form data integrity of all samples
254 - added and implemented new parameter "--rebuild-checksums" which allows
255 to recalculate the CRC32 checksum of all samples' raw wave data and
256 rebuilding the gig file's global checksum table (i.e. in case the
257 file's checksum table was damaged)
258 - print samples' CRC32 checksums
259 - Print the new EG behavior options (eg_opt_t).
260
261 * src/tools/gigextract.cpp:
262 - Fix: if sample name contains a path separator (slash or backslash) then
263 replace them by a minus sign to avoid file system issues.
264
265 * src/tools/gig2stereo.cpp:
266 - Also merge mono sample pairs with non matching loop information if
267 argument --incompatible was given.
268

306
307 * AKAI file format:
308 - Added Linux/POSIX ported version of libakai. Note that libakai is released
309 under LGPL terms while libgig is released under GPL terms. To handle this
310 license difference appropriately the AKAI support part is built as
311 separate DLL (.so file).
312 - Fixed Mac OSX support so that the Akai lib files and tools compile without
313 any exotic third party libraries.
314 - Fixed various compilation errors for Windows.

415 * src/RIFF.cpp, src/RIFF.h:
416 - bugfix: saving to the same file after the file size had been
417 increased made the file corrupt (#82)
418 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
419 is not written physically yet (#82)

423 length files, now throws a RIFF::Exception instead (fixes bug #121)
424 - bugfix: destructor for base class RIFF::Chunk accessed members
425 of derived class RIFF::File, which is bad, and caused crashes
426 when using Visual C++
427 - bugfix: files that contain zero length RIFF lists were not read
428 correctly (fixes #127) (bug was introduced 2009-03-13)

470 instrument constructors
471 - clear unused fields when saving samples and regions
472 - fixed write support bugs: v3 dimension limits and chunksize
473 weren't saved, leverage controller of type controlchange
474 couldn't be saved, group name list chunk was placed wrong,
475 dimension region chunks also placed wrong
476 - added initialization of some fixed info strings in file and
477 instrument
478 - write support: files created by libgig will now have the RIFF
479 chunks in correct order
480 - write support: two previously unknown fields in dimension
481 definition are now saved
482 - added constants for gig file versions
483 - write support: the 3crc and einf chunks are now created or
484 updated when a file is saved (3crc contains sample checksums,
485 einf contains file statistics)
486 - write support: DLSID is now generated on the file and the
487 instruments
488 - write support: improved the default values for dimension region
489 parameters
490 - more write support fixes: crossfade parameters were not saved,
491 v3 dimension limits were not correctly initialized and saved
492 when dimensions were added or deleted, v3 wave pool offsets were
493 not saved correctly
494 - write support: 24 bit samples can now be written
495 - write support: version 3 is now the default for new files
496 - more write support fixes: the 3ewg chunk is now bigger for v3,
497 dimension regions without mapped samples are now allowed, 3gnl
498 list in v3 files now always has 128 entries, several parameters
499 where incorrectly saved due to an operator precedence mistake
500 - DeleteSample now removes all references to the deleted sample
501 - AddDimension now copies all parameters from existing dimension
502 regions and also makes sure that the samplechannel dimension is
503 placed first in the list of dimensions.
504 - added method GetParent() to class 'DimensionRegion', which returns its
505 parent Region
506 - fixed Instrument::UpdateRegionKeyTable() method which did not reset
507 unused areas
508 - added various setter methods to DimensionRegion class which take care
509 of updating lookup tables / caches.
510

532 that is File::DeleteGroup() now removes not just the group, but also
533 all the samples that belong to that group
534 - fixed crash which occured on interfering File::DeleteSample() and
535 File::GetNextSample() calls (due to iterator invalidation)

538 with the group
539 - added Instrument::MoveRegion method
540 - fixed constructor for Region, which did not initialize correctly
541 when used from Instrument::AddRegion
542 - when saving, override the gig::Regions sample reference simply by
543 the region's first dimension region's sample (avoids an exception
544 when trying to save a new instrument)
545 - fixed AddDimension() method which did not fill out all mandatory
546 dimension definition fields
547
548 * src/DLS.cpp, src/DLS.h:

681 articulation informations are ignored at the moment
682 (patch by Andreas Persson)
683 - added some file format compatibility checks
684 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

739 SuSE and Fedora)
740 - fixed generation of Doxygen API documentation (now also included in
741 RPM and Debian packages)
742
743 * src/gig.cpp, src/gig.h:
744 - fixed / improved accuracy of all three velocity to volume
745 transformation functions a.k.a. 'nonlinear','linear','special'
746 (patch by Andreas Persson)
747 - denormals are filtered from the velocity to volume tables
748 - bugfix for dimension region switching (wrong handling of the release
749 trigger dimension, no bit range check for dimensions of split type
750 'split_type_bit')

752 signed 7 bit to signed 8 bit)
753 - added class attribute 'Layers' to class 'gig::Region'
754 - symbol prototyping of gig::Region (fixes build failure with qsampler)
755

775 - added support for generating Debian packages
776 - version of shared library can be set in configure.in
777
778 Version 0.7.0 (3 May 2004)
779
780 * general changes:
781 - various big endian specific corrections
782 (successfully tested now on PPC)
783 - minor adjustments to avoid compile errors on some systems
784 (using now pow() instead of powl() and --pedantic g++ compiler switch)
785 - libtoolized the library
786 - added man pages for the command line tools
787 (gigextract, gigdump, dlsdump, rifftree)
788
789 * src/gig.cpp, src/gig.h:
790 - fixed bug in decompression algorithm which caused it not to detect
791 the end of a stream
792 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
793 takes the MIDI key velocity value as an argument and returns the
794 appropriate volume factor (0.0 ... 1.0) for the sample to be played
795 back, the velocity curve transformation functions used for this are
796 only an approximation so far
797 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
798 'Sample::LoopSize' which reflected wrong values
799 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
800 measured in sample points instead of byte offset
801 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
802 'Sample::FineTune'
803 - added class attribute 'Sample::LoopSize'
804 - added method GetInstrument(uint index) to class 'File'
805 - added ReadAndLoop() method to class 'Sample' which is an extension to
806 the normal Read() method to honor the sample's looping information
807 while streaming from disk
808 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
809 'eg2_ctrl_t': replaced this huge enumeration by a structure which
810 reflects the MIDI controller number in case of an ordinary control
811 change controller (this saves a huge switch-case block in the
812 application of the library user)
813 - renamed following attributes in class 'DimensionRegion':
814 'AttenuationContol' -> 'AttenuationController',
815 'InvertAttenuationControl' -> 'InvertAttenuationController',
816 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
817 - minor fix in API documentation for method GetVelocityAttenuation() in
818 class 'DimensionRegion'
819
820 * src/RIFF.cpp, src/RIFF.h:
821 - added additional API documentation
822 - minor fix in Chunk::Read() method (only a minor efficiency issue)
823
824 * src/gigdump.cpp:
825 - added printout of samples' looping informations
826
827 Version 0.6.0 (3 Nov 2003)
828
829 * initial release
