File size: 32063 byte(s)
* Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
  (original patch by Paul Brossier, slightly modified).
* Bumped version (4.0.0.svn31).

1 Version SVN trunk
2 * general changes:
3 - removed 2 GB limitation when loading a gig or DLS file
4 - using now native integer size where appropriate
5 - fixed minor issues with man pages (patch by Debian maintainer)
6 - fixed various spelling mistakes (patch by Debian maintainer)
7 - Added new "Serialization" framework (and equally named namespace)
8 which allows to serialize and deserialize native C++ objects
9 in a portable, easy and flexible way.
10 - print compiler warning if no RTTI available
11 - Fixed potential crash in command line tools gig2stereo, korg2gig,
12 korgdump and sf2extract.
13 - Fixed CVE-2017-12950, CVE-2017-12952, CVE-2017-12953
14 (original patch by Paul Brossier, slightly modified).
15
16 * src/gig.cpp, src/gig.h:
17 - fixed bug in Script::SetGroup: the script chunk wasn't moved
18 - fixed compilation error with clang 3.4
19 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
20 as one single monolithic gig file. In case .gig file is >= 2GB expect a
21 large monolithic file, otherwise if .gig file is < 2 GB check for
22 "extension" files (.gx01, .gx02, ...) instead.
23 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
24 if there were dimensions after the velocity dimension: it only created
25 valid velocity tables for cases of dimensions lower than the velocity
26 dimension.
27 - added new method Sample::VerifyWaveData() which allows to check whether
28 a sample had been damaged for some reason
29 - Fix: samples' CRC checksums were damaged on file structure changes.
30 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
31 - Added new method Sample::GetWaveDataCRC32Checksum().
32 - Changed default value of EG2Release (filter release time) to 60s.
33 - Instruments' default pitch bend range is now +-2 semi tones.
34 - Fixed CRC checksums being wrong sometimes.
35 - Fix: method File::AddContentOf() did not clone script groups and scripts
36 of passed original file.
37 - Added support for serializing & deserializing DimensionRegion
38 objects (and crossfade_t and leverage_ctrl_t objects).
39 - Added enum reflection API functions for retrieving enum declaration type
40 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
41 - Exception class now has a variadic constructor which allows to add
42 textual format specifiers like with printf().
43 - On unknown leverage controller exception: show precise unknown leverage
44 controller number found.
45 - Ignore invalid leverage controller types and just show a warning on the
46 console instead of throwing an exception.
47 - Added new struct eg_opt_t and new class member variable
48 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
49 extension to the gig file format, which allows to override the default
50 behavior of the first two EGs' state machines.
51
52 * src/DLS.cpp, src/DLS.h:
53 - Sample: wave pool offsets are now 64 bits (to allow support for files
54 larger than 4 GB).
55 - Exception class now has a variadic constructor which allows to add
56 textual format specifiers like with printf().
57
58 * src/RIFF.cpp, src/RIFF.h:
59 - added support for RIFF files larger than 4 GB, by default the required
60 internal RIFF file offset size is automatically detected (that is RIFF
61 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
62 automatically use 64 bit offsets), a particular offset size can be forced
63 with a new option added to the RIFF File constructor though
64 - when saving a modified, grown RIFF file, the temporary file size during
65 Save() operation will no longer be larger than the final grown file size
66 - Exception class now has a variadic constructor which allows to add
67 textual format specifiers like with printf().
68
69 * src/Serialization.cpp, src/Serialization.h:
70 - Archive: Added method isModified().
71 - Archive: Added method setAutoValue().
72 - Archive: Added method setIntValue().
73 - Archive: Added method setRealValue().
74 - Archive: Added method setBoolValue().
75 - Archive: Added method setEnumValue().
76 - Archive: Added method valueAsString().
77 - Archive::rawData(): Automatically re-encode new raw data stream if
78 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
79 - Object: Added method memberByUID().
80 - Object: remove() method is now protected.
81 - Archive: Added method removeMember().
82 - Archive: Added methods name() and setName().
83 - Archive: Added methods comment() and setComment().
84 - Archive: Added methods timeStampCreated(), timeStampModified(),
85 dateTimeCreated() and dateTimeModified().
86 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
87 - DataType: Implemented demangling C++ type names (for methods
88 asLongDescr() and customTypeName(bool demangle=false)).
89 - Archive::setAutoValue(): Handle human readable boolean text
90 representations like "yes", "no", "true", "false" as expected.
91 - Exception class now has a variadic constructor which allows to add
92 textual format specifiers like with printf().
93 - DataType fix: Retain backward compatibility to older versions of native
94 C++ classes/structs.
95
96 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
97 - improved output of non-ascii characters in usage messages

108 data
109 - added and implemented new parameter "--verify" which allows to check
110 the raw wave form data integrity of all samples
111 - added and implemented new parameter "--rebuild-checksums" which allows
112 to recalculate the CRC32 checksum of all samples' raw wave data and
113 rebuilding the gig file's global checksum table (i.e. in case the
114 file's checksum table was damaged)
115 - print samples' CRC32 checksums
116 - Print the new EG behavior options (eg_opt_t).
117
118 * src/tools/gigextract.cpp:
119 - Fix: if sample name contains a path separator (slash or backslash) then
120 replace them by a minus sign to avoid file system issues.
121
122 * src/tools/gig2stereo.cpp:
123 - Also merge mono sample pairs with non matching loop information if
124 argument --incompatible was given.
125

240 one allows to move the subchunk from the current list to another list
241 - POSIX: only assume -1 result value as error on open() calls
242 - POSIX: show operating system's error reason if opening a file failed

269 - fixed crash which occured when streaming a gig sample with
270 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
271
272 * src/RIFF.cpp, src/RIFF.h:
273 - bugfix: saving to the same file after the file size had been
274 increased made the file corrupt (#82)
275 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
276 is not written physically yet (#82)

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

395 with the group
396 - added Instrument::MoveRegion method
397 - fixed constructor for Region, which did not initialize correctly
398 when used from Instrument::AddRegion
399 - when saving, override the gig::Regions sample reference simply by
400 the region's first dimension region's sample (avoids an exception
401 when trying to save a new instrument)

504 function to DimensionRegion
505
506 * src/DLS.cpp, src/DLS.h:

510 * src/RIFF.cpp, src/RIFF.h:
511 - the file name is remembered in the RIFF::File object
512

532 - man pages are now auto generated with the correct libgig version
533
534 * src/gig.cpp, src/gig.h:
535 - experimental support for Gigasampler v3 format;
536 64 bit file offsets are truncated to 32 bit, 24 bit samples are
537 truncated to 16 bit, up to 8 dimensions are read, additional
538 articulation informations are ignored at the moment
539 (patch by Andreas Persson)
540 - added some file format compatibility checks
541 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
542 never used, because the necessary check was made before
543 initialization)
544 - fixed crossfade points order (structure for big endian and little
545 endian systems was interchanged)
546 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)

588 used libgig version
589
590 Version 1.0.0 (26 Nov 2004)
591
592 * packaging changes:
593 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
594 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
595 - fixed man pages automake install rule (which didn't work on Mandrake,
596 SuSE and Fedora)
597 - fixed generation of Doxygen API documentation (now also included in
598 RPM and Debian packages)
599
600 * src/gig.cpp, src/gig.h:
601 - fixed / improved accuracy of all three velocity to volume
602 transformation functions a.k.a. 'nonlinear','linear','special'
603 (patch by Andreas Persson)
604 - denormals are filtered from the velocity to volume tables
605 - bugfix for dimension region switching (wrong handling of the release
606 trigger dimension, no bit range check for dimensions of split type
607 'split_type_bit')
608 - fixed panorama value in DimensionRegion (invalid conversion from
609 signed 7 bit to signed 8 bit)
610 - added class attribute 'Layers' to class 'gig::Region'
611 - symbol prototyping of gig::Region (fixes build failure with qsampler)
612
613 * src/gigextract.cpp:
614 - added support for libsndfile (if libaudiofile and libsndfile are
615 available then libsndfile is preferred)
616
617 * src/gigdump.cpp:
618 - added printout for dimension informations (amount, type, bits, zones)
619 - added printout for velocity response curve parameters
620 - added printout for crossfade definitions
621 - added printout for panorama value for each DimensionRegion
622 - replaced printout of DLS Region layer by printout of amount of
623 Gigasampler layers
624
625 Version 0.7.1 (2 Jul 2004)
626
627 * packaging changes:
628 - added libgig.spec and libgig.pc package configurations for generating
629 Redhat packages
630 - header files included on installation.
631 - autotools-generated files removed from CVS repository.
632 - added support for generating Debian packages
633 - version of shared library can be set in configure.in
634
635 Version 0.7.0 (3 May 2004)
636
637 * general changes:
638 - various big endian specific corrections
639 (successfully tested now on PPC)
640 - minor adjustments to avoid compile errors on some systems
641 (using now pow() instead of powl() and --pedantic g++ compiler switch)
642 - libtoolized the library
643 - added man pages for the command line tools
644 (gigextract, gigdump, dlsdump, rifftree)
645
646 * src/gig.cpp, src/gig.h:
647 - fixed bug in decompression algorithm which caused it not to detect
648 the end of a stream
649 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
650 takes the MIDI key velocity value as an argument and returns the
651 appropriate volume factor (0.0 ... 1.0) for the sample to be played
652 back, the velocity curve transformation functions used for this are
653 only an approximation so far
654 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
655 'Sample::LoopSize' which reflected wrong values
656 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
657 measured in sample points instead of byte offset
658 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
659 'Sample::FineTune'
660 - added class attribute 'Sample::LoopSize'
661 - added method GetInstrument(uint index) to class 'File'
662 - added ReadAndLoop() method to class 'Sample' which is an extension to
663 the normal Read() method to honor the sample's looping information
664 while streaming from disk
665 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
666 'eg2_ctrl_t': replaced this huge enumeration by a structure which
667 reflects the MIDI controller number in case of an ordinary control
668 change controller (this saves a huge switch-case block in the
669 application of the library user)
670 - renamed following attributes in class 'DimensionRegion':
671 'AttenuationContol' -> 'AttenuationController',
672 'InvertAttenuationControl' -> 'InvertAttenuationController',
673 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
674 - minor fix in API documentation for method GetVelocityAttenuation() in
675 class 'DimensionRegion'
676
677 * src/RIFF.cpp, src/RIFF.h:
678 - added additional API documentation
679 - minor fix in Chunk::Read() method (only a minor efficiency issue)
680
681 * src/gigdump.cpp:
682 - added printout of samples' looping informations
683
684 Version 0.6.0 (3 Nov 2003)
685
686 * initial release
