Revision 3369 - (show annotations) (download)
Fri Nov 24 22:48:43 2017 UTC (6 years, 4 months ago) by schoenebeck
File size: 32552 byte(s)
* src/Akai.cpp: Fixed compilation error with recent, more
  strict compilers.
* Bumped version (4.0.0.svn34).

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 - Debian: Fixed packaging error about invalid substitution variable
16 "Source-Version".
17 - Raised Debian compatibility level to Debian 9 "Stretch".
18
19 * src/gig.cpp, src/gig.h:
20 - fixed bug in Script::SetGroup: the script chunk wasn't moved
21 - fixed compilation error with clang 3.4
22 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
23 as one single monolithic gig file. In case .gig file is >= 2GB expect a
24 large monolithic file, otherwise if .gig file is < 2 GB check for
25 "extension" files (.gx01, .gx02, ...) instead.
26 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
27 if there were dimensions after the velocity dimension: it only created
28 valid velocity tables for cases of dimensions lower than the velocity
29 dimension.
30 - added new method Sample::VerifyWaveData() which allows to check whether
31 a sample had been damaged for some reason
32 - Fix: samples' CRC checksums were damaged on file structure changes.
33 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
34 - Added new method Sample::GetWaveDataCRC32Checksum().
35 - Changed default value of EG2Release (filter release time) to 60s.
36 - Instruments' default pitch bend range is now +-2 semi tones.
37 - Fixed CRC checksums being wrong sometimes.
38 - Fix: method File::AddContentOf() did not clone script groups and scripts
39 of passed original file.
40 - Added support for serializing & deserializing DimensionRegion
41 objects (and crossfade_t and leverage_ctrl_t objects).
42 - Added enum reflection API functions for retrieving enum declaration type
43 information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
44 - Exception class now has a variadic constructor which allows to add
45 textual format specifiers like with printf().
46 - On unknown leverage controller exception: show precise unknown leverage
47 controller number found.
48 - Ignore invalid leverage controller types and just show a warning on the
49 console instead of throwing an exception.
50 - Added new struct eg_opt_t and new class member variable
51 DimensionRegion::EG1Options and DimensionRegion::EG2Options as an
52 extension to the gig file format, which allows to override the default
53 behavior of the first two EGs' state machines.
54 - Fixed undefined behavior when loading a gig file with invalid
55 velocity curve parameters (fixes CVE-2017-12951).
56 - Fixed undefined behavior when loading a gig file with invalid wave
57 pool index number (fixes CVE-2017-12954).
58
59 * src/DLS.cpp, src/DLS.h:
60 - Sample: wave pool offsets are now 64 bits (to allow support for files
61 larger than 4 GB).
62 - Exception class now has a variadic constructor which allows to add
63 textual format specifiers like with printf().
64
65 * src/RIFF.cpp, src/RIFF.h:
66 - added support for RIFF files larger than 4 GB, by default the required
67 internal RIFF file offset size is automatically detected (that is RIFF
68 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
69 automatically use 64 bit offsets), a particular offset size can be forced
70 with a new option added to the RIFF File constructor though
71 - when saving a modified, grown RIFF file, the temporary file size during
72 Save() operation will no longer be larger than the final grown file size
73 - Exception class now has a variadic constructor which allows to add
74 textual format specifiers like with printf().
75
76 * src/Serialization.cpp, src/Serialization.h:
77 - Archive: Added method isModified().
78 - Archive: Added method setAutoValue().
79 - Archive: Added method setIntValue().
80 - Archive: Added method setRealValue().
81 - Archive: Added method setBoolValue().
82 - Archive: Added method setEnumValue().
83 - Archive: Added method valueAsString().
84 - Archive::rawData(): Automatically re-encode new raw data stream if
85 archive had been modified (i.e. by remove(), setAutoValue(), etc.).
86 - Object: Added method memberByUID().
87 - Object: remove() method is now protected.
88 - Archive: Added method removeMember().
89 - Archive: Added methods name() and setName().
90 - Archive: Added methods comment() and setComment().
91 - Archive: Added methods timeStampCreated(), timeStampModified(),
92 dateTimeCreated() and dateTimeModified().
93 - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
94 - DataType: Implemented demangling C++ type names (for methods
95 asLongDescr() and customTypeName(bool demangle=false)).
96 - Archive::setAutoValue(): Handle human readable boolean text
97 representations like "yes", "no", "true", "false" as expected.
98 - Exception class now has a variadic constructor which allows to add
99 textual format specifiers like with printf().
100 - DataType fix: Retain backward compatibility to older versions of native
101 C++ classes/structs.

119 - added and implemented new parameter "--verify" which allows to check
120 the raw wave form data integrity of all samples
121 - added and implemented new parameter "--rebuild-checksums" which allows
122 to recalculate the CRC32 checksum of all samples' raw wave data and
123 rebuilding the gig file's global checksum table (i.e. in case the
124 file's checksum table was damaged)
125 - print samples' CRC32 checksums
126 - Print the new EG behavior options (eg_opt_t).
127
128 * src/tools/gigextract.cpp:
129 - Fix: if sample name contains a path separator (slash or backslash) then
130 replace them by a minus sign to avoid file system issues.
131
132 * src/tools/gig2stereo.cpp:
133 - Also merge mono sample pairs with non matching loop information if
134 argument --incompatible was given.

248 - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
249 allows to move a subchunk within the current List, whereas the new 2nd
250 one allows to move the subchunk from the current list to another list
251 - POSIX: only assume -1 result value as error on open() calls
252 - POSIX: show operating system's error reason if opening a file failed

279 - fixed crash which occured when streaming a gig sample with
280 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
281
282 * src/RIFF.cpp, src/RIFF.h:
283 - bugfix: saving to the same file after the file size had been
284 increased made the file corrupt (#82)
285 - bugfix: refuse Chunk::Read() in case chunk has just been added, that
286 is not written physically yet (#82)

337 instrument constructors
338 - clear unused fields when saving samples and regions
339 - fixed write support bugs: v3 dimension limits and chunksize

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

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

512 instead of an approximation
513 - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
514 function to DimensionRegion
515
516 * src/DLS.cpp, src/DLS.h:

543
544 * src/gig.cpp, src/gig.h:
545 - experimental support for Gigasampler v3 format;
546 64 bit file offsets are truncated to 32 bit, 24 bit samples are

548 articulation informations are ignored at the moment
549 (patch by Andreas Persson)
550 - added some file format compatibility checks
551 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
552 never used, because the necessary check was made before

600 Version 1.0.0 (26 Nov 2004)
601
602 * packaging changes:
603 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
604 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
605 - fixed man pages automake install rule (which didn't work on Mandrake,
606 SuSE and Fedora)
607 - fixed generation of Doxygen API documentation (now also included in
608 RPM and Debian packages)
609
610 * src/gig.cpp, src/gig.h:
611 - fixed / improved accuracy of all three velocity to volume
612 transformation functions a.k.a. 'nonlinear','linear','special'
613 (patch by Andreas Persson)
614 - denormals are filtered from the velocity to volume tables
615 - bugfix for dimension region switching (wrong handling of the release
616 trigger dimension, no bit range check for dimensions of split type
617 'split_type_bit')
618 - fixed panorama value in DimensionRegion (invalid conversion from
619 signed 7 bit to signed 8 bit)
620 - added class attribute 'Layers' to class 'gig::Region'
621 - symbol prototyping of gig::Region (fixes build failure with qsampler)
622
623 * src/gigextract.cpp:
624 - added support for libsndfile (if libaudiofile and libsndfile are
625 available then libsndfile is preferred)
626
627 * src/gigdump.cpp:
628 - added printout for dimension informations (amount, type, bits, zones)
629 - added printout for velocity response curve parameters
630 - added printout for crossfade definitions
631 - added printout for panorama value for each DimensionRegion
632 - replaced printout of DLS Region layer by printout of amount of
633 Gigasampler layers
634
635 Version 0.7.1 (2 Jul 2004)
636
637 * packaging changes:
638 - added libgig.spec and libgig.pc package configurations for generating
639 Redhat packages
640 - header files included on installation.
641 - autotools-generated files removed from CVS repository.
642 - added support for generating Debian packages
643 - version of shared library can be set in configure.in
644
645 Version 0.7.0 (3 May 2004)
646
647 * general changes:
648 - various big endian specific corrections
649 (successfully tested now on PPC)
650 - minor adjustments to avoid compile errors on some systems
651 (using now pow() instead of powl() and --pedantic g++ compiler switch)
652 - libtoolized the library
653 - added man pages for the command line tools
654 (gigextract, gigdump, dlsdump, rifftree)
655
656 * src/gig.cpp, src/gig.h:
657 - fixed bug in decompression algorithm which caused it not to detect
658 the end of a stream
659 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
660 takes the MIDI key velocity value as an argument and returns the
661 appropriate volume factor (0.0 ... 1.0) for the sample to be played
662 back, the velocity curve transformation functions used for this are
663 only an approximation so far
664 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
665 'Sample::LoopSize' which reflected wrong values
666 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
667 measured in sample points instead of byte offset
668 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
669 'Sample::FineTune'
670 - added class attribute 'Sample::LoopSize'
671 - added method GetInstrument(uint index) to class 'File'
672 - added ReadAndLoop() method to class 'Sample' which is an extension to
673 the normal Read() method to honor the sample's looping information
674 while streaming from disk
675 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
676 'eg2_ctrl_t': replaced this huge enumeration by a structure which
677 reflects the MIDI controller number in case of an ordinary control
678 change controller (this saves a huge switch-case block in the
679 application of the library user)
680 - renamed following attributes in class 'DimensionRegion':
681 'AttenuationContol' -> 'AttenuationController',
682 'InvertAttenuationControl' -> 'InvertAttenuationController',
683 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
684 - minor fix in API documentation for method GetVelocityAttenuation() in
685 class 'DimensionRegion'
686
687 * src/RIFF.cpp, src/RIFF.h:
688 - added additional API documentation
689 - minor fix in Chunk::Read() method (only a minor efficiency issue)
690
691 * src/gigdump.cpp:
692 - added printout of samples' looping informations
693
694 Version 0.6.0 (3 Nov 2003)
695
696 * initial release
