File size: 32308 byte(s)
* src/gig.cpp: Fixed undefined behavior when loading a gig file with
  invalid wave pool index number (fixes CVE-2017-12954).
* Bumped version (4.0.0.svn33).

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 - Fixed undefined behavior when loading a gig file with invalid
52 velocity curve parameters (fixes CVE-2017-12951).
53 - Fixed undefined behavior when loading a gig file with invalid wave
54 pool index number (fixes CVE-2017-12954).
55
56 * src/DLS.cpp, src/DLS.h:
57 - Sample: wave pool offsets are now 64 bits (to allow support for files
58 larger than 4 GB).
59 - Exception class now has a variadic constructor which allows to add
60 textual format specifiers like with printf().
61
62 * src/RIFF.cpp, src/RIFF.h:
63 - added support for RIFF files larger than 4 GB, by default the required
64 internal RIFF file offset size is automatically detected (that is RIFF
65 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
66 automatically use 64 bit offsets), a particular offset size can be forced
67 with a new option added to the RIFF File constructor though
68 - when saving a modified, grown RIFF file, the temporary file size during
69 Save() operation will no longer be larger than the final grown file size
70 - Exception class now has a variadic constructor which allows to add
71 textual format specifiers like with printf().
72
73 * src/Serialization.cpp, src/Serialization.h:
74 - Archive: Added method isModified().
75 - Archive: Added method setAutoValue().
76 - Archive: Added method setIntValue().
77 - Archive: Added method setRealValue().
78 - Archive: Added method setBoolValue().
79 - Archive: Added method setEnumValue().
80 - Archive: Added method valueAsString().
81 - Archive::rawData(): Automatically re-encode new raw data stream if
82 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
83 - Object: Added method memberByUID().
84 - Object: remove() method is now protected.
85 - Archive: Added method removeMember().
86 - Archive: Added methods name() and setName().
87 - Archive: Added methods comment() and setComment().
88 - Archive: Added methods timeStampCreated(), timeStampModified(),
89 dateTimeCreated() and dateTimeModified().
90 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
91 - DataType: Implemented demangling C++ type names (for methods
92 asLongDescr() and customTypeName(bool demangle=false)).
93 - Archive::setAutoValue(): Handle human readable boolean text
94 representations like "yes", "no", "true", "false" as expected.
95 - Exception class now has a variadic constructor which allows to add
96 textual format specifiers like with printf().
97 - DataType fix: Retain backward compatibility to older versions of native
98 C++ classes/structs.

113 - added and implemented new parameter "--verify" which allows to check
114 the raw wave form data integrity of all samples
115 - added and implemented new parameter "--rebuild-checksums" which allows
116 to recalculate the CRC32 checksum of all samples' raw wave data and
117 rebuilding the gig file's global checksum table (i.e. in case the
118 file's checksum table was damaged)
119 - print samples' CRC32 checksums
120 - Print the new EG behavior options (eg_opt_t).
121

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

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

347 - write support: DLSID is now generated on the file and the
348 instruments
349 - write support: improved the default values for dimension region
350 parameters

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

508 function to DimensionRegion
509
510 * src/DLS.cpp, src/DLS.h:

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

594 Version 1.0.0 (26 Nov 2004)
595
596 * packaging changes:
597 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
598 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
599 - fixed man pages automake install rule (which didn't work on Mandrake,
600 SuSE and Fedora)
601 - fixed generation of Doxygen API documentation (now also included in
602 RPM and Debian packages)
603
604 * src/gig.cpp, src/gig.h:
605 - fixed / improved accuracy of all three velocity to volume
606 transformation functions a.k.a. 'nonlinear','linear','special'
607 (patch by Andreas Persson)
608 - denormals are filtered from the velocity to volume tables
609 - bugfix for dimension region switching (wrong handling of the release
610 trigger dimension, no bit range check for dimensions of split type
611 'split_type_bit')
612 - fixed panorama value in DimensionRegion (invalid conversion from
613 signed 7 bit to signed 8 bit)
614 - added class attribute 'Layers' to class 'gig::Region'
615 - symbol prototyping of gig::Region (fixes build failure with qsampler)
616
617 * src/gigextract.cpp:

624 - added printout for crossfade definitions
625 - added printout for panorama value for each DimensionRegion
626 - replaced printout of DLS Region layer by printout of amount of
627 Gigasampler layers
628
629 Version 0.7.1 (2 Jul 2004)
630
631 * packaging changes:
632 - added libgig.spec and libgig.pc package configurations for generating
633 Redhat packages
634 - header files included on installation.
635 - autotools-generated files removed from CVS repository.
636 - added support for generating Debian packages
637 - version of shared library can be set in configure.in
638
639 Version 0.7.0 (3 May 2004)
640
641 * general changes:
642 - various big endian specific corrections
643 (successfully tested now on PPC)
644 - minor adjustments to avoid compile errors on some systems
645 (using now pow() instead of powl() and --pedantic g++ compiler switch)
646 - libtoolized the library
647 - added man pages for the command line tools
648 (gigextract, gigdump, dlsdump, rifftree)
649
650 * src/gig.cpp, src/gig.h:
651 - fixed bug in decompression algorithm which caused it not to detect
652 the end of a stream
653 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
654 takes the MIDI key velocity value as an argument and returns the
655 appropriate volume factor (0.0 ... 1.0) for the sample to be played
656 back, the velocity curve transformation functions used for this are
657 only an approximation so far
658 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
659 'Sample::LoopSize' which reflected wrong values
660 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
661 measured in sample points instead of byte offset
662 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
663 'Sample::FineTune'
664 - added class attribute 'Sample::LoopSize'
665 - added method GetInstrument(uint index) to class 'File'
666 - added ReadAndLoop() method to class 'Sample' which is an extension to
667 the normal Read() method to honor the sample's looping information
668 while streaming from disk
669 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
670 'eg2_ctrl_t': replaced this huge enumeration by a structure which
671 reflects the MIDI controller number in case of an ordinary control
672 change controller (this saves a huge switch-case block in the
673 application of the library user)
674 - renamed following attributes in class 'DimensionRegion':
675 'AttenuationContol' -> 'AttenuationController',
676 'InvertAttenuationControl' -> 'InvertAttenuationController',
677 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
678 - minor fix in API documentation for method GetVelocityAttenuation() in
679 class 'DimensionRegion'
680
681 * src/RIFF.cpp, src/RIFF.h:
682 - added additional API documentation
683 - minor fix in Chunk::Read() method (only a minor efficiency issue)
684
685 * src/gigdump.cpp:
686 - added printout of samples' looping informations
687
688 Version 0.6.0 (3 Nov 2003)
689
690 * initial release
