Annotation of /libgig/trunk/ChangeLog

Version SVN trunk (?)

  * src/gig.cpp, src/gig.h:
    - Fixed Doxygen API comments for enum types (currently latest Doxygen
      [v1.8.13] only supports C comments in macro arguments expansion, but
      not C++ comments; see <FindDefineArgs> lexer rules in src/pre.l of
      the Doxygen source code, which currently also filter out new line
      \n chars).
    - Added new method File::CountSamples().
    - Added new method File::CountInstruments().
    - Fixed gig v4 files falsely being handled as v2 format
      (patch by Ivan Maguidhir).
    - Added gig v4 version identifier (File::VERSION_4).
    - GIG FORMAT EXTENSION: Added attribute
      DimensionRegion::SustainReleaseTrigger which allows to define whether
      a sustain pedal up event shall cause a release trigger sample to be
      played (default: don't play release trigger sample by sustain pedal).
    - GIG FORMAT EXTENSION: Added attribute
      DimensionRegion::NoNoteOffReleaseTrigger which allows to disable the
      regular behaviour of playing release trigger sample on MIDI note-off
      events.
    - Introduced support for writing extension files (.gx01, .gx02, ...)
      (original patch by Ivan Maguidhir).

  * src/DLS.cpp, src/DLS.h:
    - File: Fixed implicitly allocated RIFF::File object never been freed.

  * src/Serialization.cpp, src/Serialization.h:
    - Hide pure internal declarations from header file to avoid numerous
      compiler warnings when building and linking against the public API.
    - Fixed comparision logic bug
    - Fixed memory leak in DataType::customTypeName().

  * src/RIFF.cpp, src/RIFF.h:
    - Fix: Calling File::SetMode() left an undefined file handle on Windows and
      caused a resource leak
    - Avoid compiler warning when building for 32 bit windows.

  * src/tools/gigdump.cpp:
    - Added command line option --instrument-names which causes only
      instrument names and their index numbers to be printed.

Version 4.1.0 (25 Nov 2017)
  * general changes:
    - removed 2 GB limitation when loading a gig or DLS file
    - using now native integer size where appropriate
    - fixed minor issues with man pages (patch by Debian maintainer)
    - fixed various spelling mistakes (patch by Debian maintainer)
    - Added new "Serialization" framework (and equally named namespace)
      which allows to serialize and deserialize native C++ objects
      in a portable, easy and flexible way.
    - print compiler warning if no RTTI available
    - Fixed potential crash in command line tools gig2stereo, korg2gig,
      korgdump and sf2extract.
    - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
      (original patch by Paul Brossier, slightly modified).
    - Debian: Fixed packaging error about invalid substitution variable
      "Source-Version".
    - Raised Debian compatibility level to Debian 9 "Stretch".

  * src/gig.cpp, src/gig.h:
    - fixed bug in Script::SetGroup: the script chunk wasn't moved
    - fixed compilation error with clang 3.4
    - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
      as one single monolithic gig file. In case .gig file is >= 2GB expect a
      large monolithic file, otherwise if .gig file is < 2 GB check for
      "extension" files (.gx01, .gx02, ...) instead.
    - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
      if there were dimensions after the velocity dimension: it only created
      valid velocity tables for cases of dimensions lower than the velocity
      dimension.
    - added new method Sample::VerifyWaveData() which allows to check whether
      a sample had been damaged for some reason
    - Fix: samples' CRC checksums were damaged on file structure changes.
    - Fix: samples' CRC checksums were misordered when a Sample was deleted.
    - Added new method Sample::GetWaveDataCRC32Checksum().
    - Changed default value of EG2Release (filter release time) to 60s.
    - Instruments' default pitch bend range is now +-2 semi tones.
    - Fixed CRC checksums being wrong sometimes.
    - Fix: method File::AddContentOf() did not clone script groups and scripts
      of passed original file.
    - Added support for serializing & deserializing DimensionRegion
      objects (and crossfade_t and leverage_ctrl_t objects).
    - Added enum reflection API functions for retrieving enum declaration type
      information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
    - Exception class now has a variadic constructor which allows to add
      textual format specifiers like with printf().
    - On unknown leverage controller exception: show precise unknown leverage
      controller number found.
    - Ignore invalid leverage controller types and just show a warning on the
      console instead of throwing an exception.
    - Added new struct eg_opt_t and new class member variable
      DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
      extension to the gig file format, which allows to override the default
      behavior of the first two EGs' state machines.
    - Fixed undefined behavior when loading a gig file with invalid
      velocity curve parameters (fixes CVE-2017-12951).
    - Fixed undefined behavior when loading a gig file with invalid wave
      pool index number (fixes CVE-2017-12954).

  * src/DLS.cpp, src/DLS.h:
    - Sample: wave pool offsets are now 64 bits (to allow support for files
      larger than 4 GB).
    - Exception class now has a variadic constructor which allows to add
      textual format specifiers like with printf().

  * src/RIFF.cpp, src/RIFF.h:
    - added support for RIFF files larger than 4 GB, by default the required
      internal RIFF file offset size is automatically detected (that is RIFF
      files < 4 GB automatically use 32 bit offsets while files >= 4 GB
      automatically use 64 bit offsets), a particular offset size can be forced
      with a new option added to the RIFF File constructor though
    - when saving a modified, grown RIFF file, the temporary file size during
      Save() operation will no longer be larger than the final grown file size
    - Exception class now has a variadic constructor which allows to add
      textual format specifiers like with printf().

  * src/Serialization.cpp, src/Serialization.h:
    - Archive: Added method isModified().
    - Archive: Added method setAutoValue().
    - Archive: Added method setIntValue().
    - Archive: Added method setRealValue().
    - Archive: Added method setBoolValue().
    - Archive: Added method setEnumValue().
    - Archive: Added method valueAsString().
    - Archive::rawData(): Automatically re-encode new raw data stream if
      archive had been modified (i.e. by remove(), setAutoValue(), etc.).
    - Object: Added method memberByUID().
    - Object: remove() method is now protected.
    - Archive: Added method removeMember().
    - Archive: Added methods name() and setName().
    - Archive: Added methods comment() and setComment().
    - Archive: Added methods timeStampCreated(), timeStampModified(),
      dateTimeCreated() and dateTimeModified().
    - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
    - DataType: Implemented demangling C++ type names (for methods
      asLongDescr() and customTypeName(bool demangle=false)).
    - Archive::setAutoValue(): Handle human readable boolean text
      representations like "yes", "no", "true", "false" as expected.
    - Exception class now has a variadic constructor which allows to add
      textual format specifiers like with printf().
    - DataType fix: Retain backward compatibility to older versions of native
      C++ classes/structs.

  * src/Akai.cpp:
    - Fixed compilation error with recent, more strict compilers.

    - additionally print VelocityUpperLimit and DimensionUpperLimits of all
      dimension regions
    - additionally print RIFF chunk file offset and RIFF chunk size of sample
      data
    - added and implemented new parameter "--verify" which allows to check
      the raw wave form data integrity of all samples
    - added and implemented new parameter "--rebuild-checksums" which allows
      to recalculate the CRC32 checksum of all samples' raw wave data and
      rebuilding the gig file's global checksum table (i.e. in case the
      file's checksum table was damaged)
    - print samples' CRC32 checksums
    - Print the new EG behavior options (eg_opt_t).

  * src/tools/gigextract.cpp:
    - Fix: if sample name contains a path separator (slash or backslash) then
      replace them by a minus sign to avoid file system issues.

  * src/tools/gig2stereo.cpp:
    - Also merge mono sample pairs with non matching loop information if
      argument --incompatible was given.

  * packaging changes:
    - Automake: set environment variable GCC_COLORS=auto to allow GCC to
      auto detect whether it (sh/c)ould output its messages in color.

    - Added support for custom progress notification while saving to DLS file.
    - Bugfix: Adding a new region in between two existing regions caused the
      new one being dropped after save operation and the gig file being tainted
      (chunks at wrong location in the RIFF tree).

  * src/SF.cpp, src/SF.h:
    - added new method Sample::ReadNoClear()

  * src/RIFF.cpp, src/RIFF.h:

      one allows to move the subchunk from the current list to another list
    - POSIX: only assume -1 result value as error on open() calls
    - POSIX: show operating system's error reason if opening a file failed
    - Added support for custom progress notification while saving to RIFF file.
    - Fixed embarrassing old bug: POSIX read() errors were never detected on

    - bugfix: saving to the same file after the file size had been
      increased made the file corrupt (#82)
    - bugfix: refuse Chunk::Read() in case chunk has just been added, that
      is not written physically yet (#82)

      instrument constructors
    - clear unused fields when saving samples and regions
    - fixed write support bugs: v3 dimension limits and chunksize
      weren't saved, leverage controller of type controlchange
      couldn't be saved, group name list chunk was placed wrong,
      dimension region chunks also placed wrong
    - added initialization of some fixed info strings in file and

    - write support: DLSID is now generated on the file and the
      instruments
    - write support: improved the default values for dimension region
      parameters
    - more write support fixes: crossfade parameters were not saved,

      when dimensions were added or deleted, v3 wave pool offsets were
      not saved correctly
    - write support: 24 bit samples can now be written
    - write support: version 3 is now the default for new files
    - more write support fixes: the 3ewg chunk is now bigger for v3,
      dimension regions without mapped samples are now allowed, 3gnl
      list in v3 files now always has 128 entries, several parameters
      where incorrectly saved due to an operator precedence mistake
    - DeleteSample now removes all references to the deleted sample
    - AddDimension now copies all parameters from existing dimension
      regions and also makes sure that the samplechannel dimension is
      placed first in the list of dimensions.
    - added method GetParent() to class 'DimensionRegion', which returns its
      parent Region
    - fixed Instrument::UpdateRegionKeyTable() method which did not reset
      unused areas

    - added support for custom splits points for other dimensions than
      velocity (gig v3 feature)
    - added "smart midi" and "round robin keyboard" dimensions
    - added new method File::DeleteGroupOnly() which only deletes the given
      group but moves all its members to another group, the other method,
      that is File::DeleteGroup() now removes not just the group, but also
      all the samples that belong to that group
    - fixed crash which occured on interfering File::DeleteSample() and
      File::GetNextSample() calls (due to iterator invalidation)
    - fixed group names which were not saved

    - fixed constructor for Region, which did not initialize correctly
      when used from Instrument::AddRegion
    - when saving, override the gig::Regions sample reference simply by
      the region's first dimension region's sample (avoids an exception
      when trying to save a new instrument)
    - fixed AddDimension() method which did not fill out all mandatory
      dimension definition fields

  * src/DLS.cpp, src/DLS.h:
    - added Instrument::MoveRegion method

      instead of the wave chunk
    - keyswitching dimension is changed from split type "normal" to

    - added write support (that is for creating and modifying RIFF, DLS and
      gig files)
    - loading DLS and gig files is now much more permissive, DLS and gig
      files are now loaded even if mandatory RIFF chunks are missing
    - fixed some memory management errors, one of them was causing a
      crash when a multi-file gig was deallocated

  * src/gig.cpp, src/gig.h:
    - fixed the GetVelocityCutoff function, it wasn't always using the
      VCFVelocityScale parameter when no cutoff controller was defined

      (mandatory for 'dist-bzip2' automake option)

  * src/gig.cpp, src/gig.h:
    - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
      the extension files are read automatically when the samples are
      loaded
    - fixed the 24 bit decompression, the result should now be exact
      instead of an approximation
    - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
      function to DimensionRegion

  * src/DLS.cpp, src/DLS.h:
    - the upper bits of the pool table indices are read (used as
      extension file numbers for gig v3)

  * src/RIFF.cpp, src/RIFF.h:
    - the file name is remembered in the RIFF::File object

Version 2.0.1 (12 Jun 2005)

  * packaging changes:
    - include debian/ directory on 'make dist'
    - create a bzip2 tarball on 'make dist'

  * src/gigextract.cpp:
    - show also version of libsndfile or build version of libaudiofile when
      using the -v switch
    - fixed mutual link dependency to libsndfile / libaudiofile

  * src/gig.cpp, src/gig.h:
    - added DimensionRegion::GetVelocityRelease function

Version 2.0.0 (9 May 2005)

  * packaging changes:
    - fixed conditional linkage of either libsndfile or libaudiofile
      (if none of the two exist, configure script will abort)
    - man pages are now auto generated with the correct libgig version

  * src/gig.cpp, src/gig.h:
    - experimental support for Gigasampler v3 format;
      64 bit file offsets are truncated to 32 bit, 24 bit samples are
      truncated to 16 bit, up to 8 dimensions are read, additional
      articulation informations are ignored at the moment
      (patch by Andreas Persson)
    - added some file format compatibility checks
    - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
      never used, because the necessary check was made before
      initialization)
    - fixed crossfade points order (structure for big endian and little
      endian systems was interchanged)
    - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
    - fixed crash which occured when patches did not have a sample assigned
      to their region or dimension region (patch by Andreas Persson)
    - support for compressed mono samples
    - experimental support for compressed 24 bit samples
    - fixed decompression on big-endian CPUs
    - fixed decompression bug that truncated the last block of samples

    - implemented progress indicator callback mechanism for loading
      instruments and samples

      to be zero
    - added functions libraryName() and libraryVersion()

  * src/RIFF.cpp, src/RIFF.h:
    - fixed method List::LoadSubChunks() which did not restore the original
      position within the body of the given list chunk
    - added functions libraryName() and libraryVersion()

  * src/rifftree.cpp:
    - added command line switch -v to show rifftree's revision and the used
      libgig version

  * src/dlsdump.cpp:
    - added command line switch -v to show dlsdump's revision and the used
      libgig version

  * src/gigdump.cpp:
    - added output of UnityNote, FineTune, Gain, SampleStartOffset an
      LoopPlayCount
    - added command line switch -v to show gigdump's revision and the used
      libgig version

  * src/gigextract.cpp:
    - support for compressed mono samples and compressed 24 bit samples
    - added command line switch -v to show gigextract's revision and the
      used libgig version

Version 1.0.0 (26 Nov 2004)

  * packaging changes:
    - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
      'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
    - fixed man pages automake install rule (which didn't work on Mandrake,
      SuSE and Fedora)
    - fixed generation of Doxygen API documentation (now also included in
      RPM and Debian packages)

  * src/gig.cpp, src/gig.h:
    - fixed / improved accuracy of all three velocity to volume
      transformation functions a.k.a. 'nonlinear','linear','special'
      (patch by Andreas Persson)
    - denormals are filtered from the velocity to volume tables
    - bugfix for dimension region switching (wrong handling of the release
      trigger dimension, no bit range check for dimensions of split type
      'split_type_bit')
    - fixed panorama value in DimensionRegion (invalid conversion from
      signed 7 bit to signed 8 bit)
    - added class attribute 'Layers' to class 'gig::Region'
    - symbol prototyping of gig::Region (fixes build failure with qsampler)

  * src/gigextract.cpp:
    - added support for libsndfile (if libaudiofile and libsndfile are
      available then libsndfile is preferred)

  * src/gigdump.cpp:
    - added printout for dimension informations (amount, type, bits, zones)
    - added printout for velocity response curve parameters
    - added printout for crossfade definitions
    - added printout for panorama value for each DimensionRegion
    - replaced printout of DLS Region layer by printout of amount of
      Gigasampler layers

Version 0.7.1 (2 Jul 2004)

  * packaging changes:
    - added libgig.spec and libgig.pc package configurations for generating
      Redhat packages
    - header files included on installation.
    - autotools-generated files removed from CVS repository.
    - added support for generating Debian packages
    - version of shared library can be set in configure.in

Version 0.7.0 (3 May 2004)

  * general changes:
    - various big endian specific corrections
      (successfully tested now on PPC)
    - minor adjustments to avoid compile errors on some systems
      (using now pow() instead of powl() and --pedantic g++ compiler switch)
    - libtoolized the library
    - added man pages for the command line tools
      (gigextract, gigdump, dlsdump, rifftree)

  * src/gig.cpp, src/gig.h:
    - fixed bug in decompression algorithm which caused it not to detect
      the end of a stream
    - added method GetVelocityAttenuation() to class 'DimensionRegion' which
      takes the MIDI key velocity value as an argument and returns the
      appropriate volume factor (0.0 ... 1.0) for the sample to be played
      back, the velocity curve transformation functions used for this are
      only an approximation so far
    - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
      'Sample::LoopSize' which reflected wrong values
    - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
      measured in sample points instead of byte offset
    - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
      'Sample::FineTune'
    - added class attribute 'Sample::LoopSize'
    - added method GetInstrument(uint index) to class 'File'
    - added ReadAndLoop() method to class 'Sample' which is an extension to
      the normal Read() method to honor the sample's looping information
      while streaming from disk
    - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
      'eg2_ctrl_t': replaced this huge enumeration by a structure which
      reflects the MIDI controller number in case of an ordinary control
      change controller (this saves a huge switch-case block in the
      application of the library user)
    - renamed following attributes in class 'DimensionRegion':
      'AttenuationContol' -> 'AttenuationController',
      'InvertAttenuationControl' -> 'InvertAttenuationController',
      'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
    - minor fix in API documentation for method GetVelocityAttenuation() in
      class 'DimensionRegion'

  * src/RIFF.cpp, src/RIFF.h:
    - added additional API documentation
    - minor fix in Chunk::Read() method (only a minor efficiency issue)

  * src/gigdump.cpp:
    - added printout of samples' looping informations

Version 0.6.0 (3 Nov 2003)
