* 0.2.6.2 release notes (Sat Dec 16 2006)
|
||||
* cdrskin man page backported from development version 0.2.7.
|
||||
* 0.2.6.3 release notes (Fri Dec 29 2006)
|

libburn-0.2.3.snapshot02.tar.gz Thu Nov 02 2006
|
||||
===============================================================================
|
||||
* Stabilized snapshot including release 0.2.4.pl01 of cdrskin
|
||||
* cdrskin 0.2.4 release notes
|
||||
* Compatibility with cdrecord has been improved in respect to drive addresses,
|
||||
audio extraction from .wav, -scanbus, -toc, drive buffer fill indicator.
|
||||
* Note: The previous snapshot01 with the same source base is handicapped by a
|
||||
broken ./configure setup. It works well on Intel compatible CPUs but is
|
||||
supposed to be unusable on big-endian architectures.

|
||||
|
||||
Build and Installation
|
||||
|
||||
From tarball
|
||||
|
||||
Obtain libburn-1.2.6.tar.gz, take it to a directory of your choice and do:
|
||||
|
||||
tar xzf libburn-1.2.6.tar.gz
|
||||
cd libburn-1.2.6
|
||||
./configure --prefix=/usr
|
||||
make
|
||||
|
||||
To make libburn accessible for running resp. application development,
|
||||
and to install the cdrecord compatibility binary cdrskin, do
|
||||
(as Superuser):
|
||||
|
||||
make install
|
||||
|
||||
This procedure installs libburn.so.4 and cdrskin depending on it.
|
||||
For a standalone cdrskin binary, see cdrskin/README.
|
||||
|
||||
A behavioral conflict is known between any burn software and demons like hald
|
||||
which probe CD drives. This can spoil burn runs for CD-R or CD-RW.
|
||||
You may have to keep your hald away from the drive. See for example
|
||||
http://www.freebsd.org/gnome/docs/halfaq.html
|
||||
|
||||
|
||||
From SVN
|
||||
|
||||
Our build system is based on autotools. For preparing the build of a SVN
|
||||
snapshot you will need autotools of at least version 1.7.
|
||||
Do in a directory of your choice:
|
||||
|
||||
svn co http://svn.libburnia-project.org/libburn/trunk libburn-svn
|
||||
cd libburn-svn
|
||||
Check out from SVN by
|
||||
svn co http://libburnia-svn.pykix.org/libburn/trunk libburn_pykix
|
||||
go into directory libburn_pykix and apply autotools by
|
||||
./bootstrap
|
||||
./configure --prefix=/usr
|
||||
|
||||
Alternatively you may unpack a release tarball for which you do not need
|
||||
autotools installed.
|
||||
|
||||
To build a libburnia.pykix.org subproject it should be sufficient to go
|
||||
into its toplevel directory (here: "libburn_pykix") and execute
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
|
||||
Warning: The trunk might contain experimental features which might not
|
||||
persist until next release.
|
||||
|
||||
|
||||
Special ./configure options
|
||||
|
||||
make install on GNU/Linux will try to run program ldconfig with the library
|
||||
installation directory as only argument. Failure to do so will not abort
|
||||
installation. One may disable ldconfig by ./configure option:
|
||||
--disable-ldconfig-at-install
|
||||
|
||||
In some situations Linux may deliver a better write performance to drives if
|
||||
the track input is read with O_DIRECT (see man 2 open). The API call
|
||||
burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
|
||||
can be told to use this peculiar read mode by:
|
||||
--enable-track-src-odirect
|
||||
|
||||
But often libburn call burn_write_opts_set_dvd_obs(opts, 64*1024) will yield
|
||||
even better performance in such a situation. 64k can be made default at
|
||||
configure time by:
|
||||
--enable-dvd-obs-64k
|
||||
This may be combined with above --enable-track-src-odirect .
|
||||
|
||||
If it is desired that DVD DAO writing and stdio: writing get padded up to
|
||||
a full write chunk of 32k resp. 64k, then use ./configure option:
|
||||
--enable-dvd-obs-pad
|
||||
|
||||
Alternatively the transport of SCSI commands can be done via libcdio-0.83.
|
||||
You may install it and re-run libburn's ./configure with option
|
||||
--enable-libcdio
|
||||
|
||||
By use of a version script, the libburn.so library exposes no other function
|
||||
names but those of the API definition in libburn/libburn.h.
|
||||
If -Wl,--version-script=... makes problems with the local compiler, then
|
||||
disable this encapsulation feature by
|
||||
--disable-versioned-libs
|
||||
|
||||
Make sure to re-compile all source files after running ./configure
|
||||
make clean ; make
|
||||
To make the libraries accessible for running resp. developing applications
|
||||
make install
|
||||
|
||||
|
||||
Linux only:
|
||||
The other half of the project, libisofs, is hosted in the libburnia SVN, too:
|
||||
svn co http://libburnia-svn.pykix.org/libisofs/trunk libisofs_pykix
|
||||
See README file there.
|
||||
|
||||
libburn tries to avoid a collision with udev's drive examination by waiting
|
||||
0.1 seconds before opening the device file for a longer time, after udev
|
||||
might have been alarmed by drive scanning activities.
|
||||
The waiting time can be set at ./configure time with microsecond granularity.
|
||||
E.g. 2 seconds:
|
||||
CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000"
|
||||
./configure ...options...
|
||||
Waiting can be disabled by zero waiting time:
|
||||
CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0"
|
||||
Alternatively, libburn can try to be nice by opening the device file,
|
||||
closing it immediately, waiting, and only then opening it for real:
|
||||
CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE -DLibburn_udev_wait_useC=500000"
|
||||
|
||||
------------------------------------------------------------------------------
|
||||
|
||||
An important part of the project, libisofs, is hosted in a bzr repository at
|
||||
launchpad.net :
|
||||
bzr branch lp:libisofs
|
||||
|
||||
Another part the project, libisoburn, is hosted in the libburnia SVN, too:
|
||||
svn co http://svn.libburnia-project.org/libisoburn/trunk libisoburn
|
||||
|

Overview of libburnia-project.org
|
||||
Overview of libburnia.pykix.org
|
||||
|
||||
libburnia-project.org is an open-source software project for reading, mastering
|
||||
libburnia.pykix.org is an open-source software project for reading, mastering
|
||||
and writing optical discs.
|
||||
For now this means CD media, all DVD media, all BD media.
|
||||
For now this means only CD media and all single layer DVD media except DVD+R.
|
||||
|
||||
The project comprises of several more or less interdependent parts which
|
||||
together strive to be a usable foundation for application development.
|
||||
These are libraries, language bindings, and middleware binaries which emulate
|
||||
classical (and valuable) Linux tools.
|
||||
Currently it is supported on GNU/Linux with kernels >= 2.4,
|
||||
on FreeBSD with ATAPI/CAM enabled in the kernel (see man atapicam),
|
||||
and on OpenSolaris (tested with kernel 5.11).
|
||||
On other X/Open compliant systems there will only be pseudo drives, but no
|
||||
direct MMC operation on real CD/DVD/BD drives.
|
||||
|
||||
For full ports to other systems we would need : login on a development machine
|
||||
resp. a live OS on CD or DVD, advise from a system person about the equivalent
|
||||
of Linux sg or FreeBSD CAM, volunteers for testing of realistic use cases.
|
||||
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
|
||||
we would need : login on a development machine resp. a live OS on CD or DVD,
|
||||
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
|
||||
volunteers for testing of realistic use cases.
|
||||
|
||||
We have a well tested code base for burning data and audio CDs, DVDs and BDs.
|
||||
We have a workable code base for burning CD and most single layer DVD.
|
||||
The burn API is quite comprehensively documented and can be used to build a
|
||||
presentable application.
|
||||
We have a functional application which emulates the core use cases of cdrecord
|
||||
in order to prove that usability, and in order to allow you to explore
|
||||
libburn's scope by help of existing cdrecord frontends.
|
||||
|
||||
ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
|
||||
and manipulated quite freely. This capability together with our burn capability
|
||||
makes possible a single binary application which covers all steps of image
|
||||
composition, updating and writing. Quite unique in the Linux world.
|
||||
We have a functional binary which emulates parts of cdrecord in order to
|
||||
prove that usability, and in order to allow you to explore libburnia's scope
|
||||
by help of existing cdrecord frontends.
|
||||
|
||||
The project components (list subject to growth, hopefully):
|
||||
|
||||
- libburn is the library by which preformatted data get onto optical media.
|
||||
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
|
||||
/dev/srM or /dev/hdX (e.g. on kernel 2.6).
|
||||
/dev/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation. Its code is
|
||||
independent of cdrecord. Its DVD capabilities are learned from
|
||||
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
|
||||
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
|
||||
|
||||
- libisofs is the library to pack up hard disk files and directories into a
|
||||
ISO 9660 disk image. This may then be brought to CD via libburn.
|
||||
An own ISO 9660 extension stores ACLs, xattr, and MD5 of file
|
||||
content.
|
||||
|
||||
- libisoburn is an add-on to libburn and libisofs which coordinates both and
|
||||
also allows to grow ISO-9660 filesystem images on multi-session
|
||||
media as well as on overwriteable media via the same API.
|
||||
All media peculiarities are handled automatically.
|
||||
It also contains the methods of command oriented application
|
||||
xorriso and offers them via a C language API.
|
||||

extracting of files from ISO images to disk. There is also a

- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
|
||||
and an upcomming integrated application for manipulating and writing
|
||||
ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
|

by these enhancements: growing of overwriteable media and disk files.
|
||||
Taking again a bow towards Andy Polyakov.
|
||||
|
||||
- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
|
||||
reliably release libburn.so.4 as should have been done since libburn-0.3.2.
|
||||
cdrskin now is by default linked dynamically and does a runtime check
|
||||
to ensure not to be started with a libburn which is older than itself.
|
||||
|
||||
- 3rd Feb 2008 libisofs-0.2.x (.so.5) has been deprecated.
|
||||
|
||||
- 14th Feb 2008 libisofs-0.6.2 permanently replaces the old libisofs-0.2.x.

API/ABI compatibility for its whole feature set.
|
||||
|
||||
- 15th Feb 2008 libisoburn-0.1.0 (.so.1) coordinates libisofs and libburn for
|
||||
the purpose of ISO image reading and writing. It emulates multi-session on
|
||||
overwriteable media. Application xorriso makes use of all three libraries.
|
||||
|
||||
- 8th Apr 2008 libburn-0.4.4 has proven to be capable of burning to DVD+R/DL
|
||||
and read performance on disk file pseudo-drives has been improved.
|
||||
|
||||
- 27th Apr 2008 libisofs-0.6.4 can now read data file content from images
|
||||
and can map pieces of disk files onto image files. Image directory iteration
|

has been enhanced. Input data streams and extended information have been
|
||||
exposed in the API to allow future development.
|
||||
|
||||
- 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of
|
||||
image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4.
|
||||
xorriso makes use of new libisofs features by performing incremental
|
||||
updates of directory trees and by cutting oversized data files into

- 11 Mar 2009 libisofs-0.6.16 of libisofs fixes two bugs which on Solaris
|
||||
prevented to navigate the ISO images by ".." and to recognize the Rock Ridge
|
||||
extensions of ISO images. The ban to build libisofs on operating systems
|
||||
other than Linux and FreeBSD has been lifted.
|
||||
|
||||
- 13 Mar 2009 libburn-0.6.4 got a dummy adapter for SCSI/MMC command transport.
|
||||
It will show no drives and thus libburn will only be able to perform
|
||||
operations on "stdio:" pseudo drives. Nevertheless this allowed to lift the
|
||||
ban to build libburn on operating systems other than Linux and FreeBSD.

in order to be mountable where mkisofs images are mountable.
|
||||
|
||||
- 17 Apr 2009 libisofs-0.6.18 introduces content filtering of data files.

mount images with such hard links but will attribute a unique inode number
|
||||
to each file.
|
||||
|
||||
- 28 Jun 2009 libisoburn-0.4.0: xorriso can record and restore hard link

data loss in older sessions if xorriso was used underneath growisofs.
|
||||
Affected are releases since libisoburn-0.3.2 in january 2009.
|
||||
|
||||
- 25 Aug 2009 libisofs-0.6.22 can record MD5 checksums for the whole session
|
||||
and for each single data file. Checksum tags allow to verify superblock and
|
||||
directory tree before importing them.
|
||||
|
||||
- 27 Aug 2009 libburn-0.7.0 allows to calm down a drive and to inquire its
|
||||
supported profiles. It works around some pitfalls with U3 enhanced memory
|
||||
sticks which emulate a CD-ROM.
|
||||
|
||||
- 27 Aug 2009 libisoburn-0.4.0.pl00 can record MD5 checksums by which one may
|
||||
verify the session or single data files in the image. When comparing image
|
||||
files with files in the local filesystem, the MD5 sums avoid the need for
|
||||
reading file content from the image.
|
||||
|
||||
- 22 Sep 2009 libisoburn-0.4.0.pl01 fixes a bug in xorriso option -cut_out.
|
||||
|
||||

shorter than 251 characters this happened only to trailing blanks.
|
||||
|
||||
- 08 Oct 2009 libisoburn-0.4.0.pl02 fixes bugs with xorriso option -for_backup,
|
||||
with xorrisofs -help, and with xorrecord -help.
|
||||
|
||||
- 12 Oct 2009 libburn-0.7.2 fixes a bug with CD TAO multi-track dummy sessions.
|
||||
It can retrieve media product info and can process track input which was
|
||||
prepared for CD-ROM XA Mode 2 Form 1. cdrskin now performs option -minfo.
|
||||
|
||||
- 28 Oct 2009 libisoburn-0.4.4 fixes a bug with cdrecord emulation and
|
||||
introduces new information options about media type and ISO image id strings.
|
||||
On Linux it helps with mounting two sessions of the same media
|
||||
simultaneously.
|
||||
|
||||
- 12 Nov 2009 libburn-0.7.2.pl01 works around problems with Pioneer DVR-216D.

|
||||
Several bugs were fixed in the libraries and in the mkisofs emulation of
|
||||
xorriso. This emulation xorrisofs has now an own man page and info document.
|
||||
|
||||
- Sat Apr 09 2011 release 1.0.6:
|
||||
libburn refined its representation of emulated drives. The size alignment
|
||||
of DVD DAO is now 2 kB rather than 32 kB. libisofs produces Joliet names of
|
||||
up to 103 characters. xorriso fixes two bugs and makes use of the library
|
||||
improvements.
|
||||
|
||||
- Thu Apr 14 2011 release libisoburn-1.0.8:
|
||||
A bug in the mkisofs emulation of xorriso could cause options to be ignored.
|
||||
The problem was freshly introduced with libisoburn-1.0.6.
|
||||
|
||||
- Fri May 13 2011 release libisofs-1.0.8:
|
||||
Fixes a few rarely occurring bugs that have been found during the last month.
|
||||
|
||||
- Sat Jun 18 2011 release 1.1.0:
|
||||
The consumption of stack memory was reduced. Statical program analysis found
|
||||
some rarely occuring memory leaks. Several small bugs were fixed.
|
||||
The suffix .plXY was dropped from tarball names of libburn and libisoburn.
|
||||
|
||||
- Mon Jun 20 2011 patch release libburn-1.1.0.pl01:
|
||||
libburn-1.1.0 compiled only on Linux, FreeBSD, and Solaris, but not on
|
||||
other X/Open compliant systems.
|
||||
|
||||
- Fri Jul 08 2011 release libisofs-1.1.2 and libisoburn-1.1.2:
|
||||
A severe regression was fixed in libisoburn and xorriso, which was introduced
|
||||
with version 1.0.6. It caused ISO 9660 images to be unreadable if they were
|
||||
written to a write-only random-access file. E.g. by: xorrisofs ... >image.iso
|
||||
|
||||
- Mon Aug 08 2011 release 1.1.4:
|
||||
Several bugs were fixed in libburn. The most severe of them prevented xorriso
|
||||
on some drives from burning mountable ISO 9660 images to CD media.
|
||||
New means to list drives by their udev symbolic links help to deal with
|
||||
the non-persistent drive addresses on modern GNU/Linux.
|
||||
|
||||
- Tue Sep 27 2011 release 1.1.6:
|
||||
libisoburn now comes with a test suite. See releng/README. Bugs were fixed
|
||||
in several rarely used features. Processing of ACL and extattr was enabled
|
||||
on FreeBSD. Workarounds try to cope with vanishing udev links on GNU/Linux.
|
||||
|
||||
- Mon Nov 21 2011 release libburn-1.1.8 and libisoburn-1.1.8:
|
||||
libburn avoids to close and open drive device files while operating on them.
|
||||
xorriso emulation mode xorrecord now has an own manual. libburn and xorriso
|
||||
were prepared to operate on qemu virtio-blk-pci devices.
|
||||
|
||||
- Sat Jan 28 2012 release 1.2.0:
|
||||
libburn has learned to read and write CD-TEXT with CD SAO audio sessions.
|
||||
It can now read CDRWIN .cue files which define pure audio or pure data
|
||||
sessions. libisofs and libisoburn improved timestamp handling. Several
|
||||
minor bugs were fixed.
|
||||
|
||||
- Mon Apr 02 2012 release 1.2.2:
|
||||
The handling of intentional deviations from ECMA-119 specifications has
|
||||
been improved in libisofs. libisoburn and xorriso now make use of these
|
||||
improvements. Some rarely occuring bugs have been fixed.
|
||||
|
||||
- Fri Jul 20 2012 release 1.2.4:
|
||||
libburn and libisofs got some rarely occuring bugs fixed. libisofs learned
|
||||
to produce HFS+ metadata and Apple Partition Map. The capabilities of
|
||||
isohybrid options --efi and --mac have been implemented (GPT and APM).
|
||||
|
||||
- Tue Jan 08 2013 release 1.2.6:
|
||||
Small improvements were made in libburn. Minor bugs were fixed in the
|
||||
libraries. xorriso improved its capabilities to serve the needs of frontend
|
||||
programs. A proof of concept for a GUI frontend has been implemented:
|
||||
xorriso-tcltk

On top of libburn there is implemented cdrskin 0.3.8, a limited cdrecord
|
||||
compatibility wrapper which allows to use some libburn features from
|
||||
the command line.
|
||||
Interested users of cdrecord are invited to participate in the development
|
||||
of cdrskin. Contact: scdbackup@gmx.net or libburn-hackers@pykix.org .

|

|

cdrskin is a limited cdrecord compatibility wrapper which allows to use
|
||||
most of the libburn features from the command line.
|
||||
|
||||
Currently it is supported on GNU/Linux with kernels >= 2.4,
|
||||
on FreeBSD and on OpenSolaris.
|
||||
IDE drives under Linux 2.4. need kernel module ide-scsi.
|
||||
ATA and SATA drives under FreeBSD need kernel module atapicam.
|
||||
On other X/Open compliant systems there will only be emulated drives, but no
|
||||
direct MMC operation on real CD/DVD/BD drives.
|
||||
Important :
|
||||
This software is provided as is. There is no warranty implied and no
|
||||
protection against possible damages. You use this on your own risk.
|
||||
Don't blame me or other authors of libburn if anything goes wrong.

||||
|

By using this software you agree to the disclaimer at the end of this text

It fails to compile or run on SuSE 6.4 (kernel 2.2.14).
|
||||
It does not find the IDE CD burner on SuSE 7.2 without ide-scsi.

systems, including 64 bit systems. (Further reports are welcome.)

A behavioral conflict is known between any burn software and demons like hald
|

which probe CD drives. This can spoil burn runs for CD-R or CD-RW.

Helpful with Linux kernel 2.4 is a special SCSI feature:
|
||||
It is possible to address a scsi(-emulated) drive via associated device files
|
||||
which are not listed by option --devices but point to the same SCSI addresses
|
||||
as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is

compatible with generic read programs like dd and with write program growisofs.

For finding /dev/sg1 from /dev/sr0, the program needs rw-access to both files.

Drive Addressing
|
||||
|
||||
Drives get addressed either via their cdrecord-style addresses as listed
|
||||
with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
|
||||
of device files.
|
||||
Not only device files listed by --devices may be used but also device files
|
||||
which via their major,minor numbers point to the same device driver as
|
||||
a listed device file.
|
||||
|
||||
Helpful with Linux kernel 2.4 is a special SCSI feature:
|
||||
It is possible to address a scsi(-emulated) drive via associated device files
|
||||
which are not listed by option --devices but point to the same SCSI addresses
|
||||
as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is
|
||||
compatible with generic read programs like dd and with write program growisofs.
|
||||
|
||||
Pseudo-SCSI Adresses
|
||||
|
||||
cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
|
||||
the meaning of the components. A cdrecord-style address for cdrskin
|
||||
[prefix:]scsibus,target,lun
|
||||
can be interpreted in two different modes.
|
||||
|
||||
Standard mode tries to be compatible to original cdrecord. This should be true
|
||||
with (emulated) SCSI where the device file /dev/s[rg]N with is looked up with
|
||||
matching scsibus,target,lun as given by the operating system.
|
||||
With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
|
||||
but matches the cdrecord addresses on all systems tested so far:
|
||||
X = 'a' + 2 * scsibus + target
|
||||
where target only may have the values 0 or 1.
|
||||
|
||||
In this mode, option -scanbus will list only SCSI devices unless option
|
||||
dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
|
||||
show IDE drives (i.e. /dev/hdX without ide-scsi emulation).
|
||||
|
||||
|
||||
In mode --old_pseudo_scsi_adr there is a scsibus,target,lun representation
|
||||
which has nothing to do with SCSI and thus is not compatible to cdrecord.
|
||||
Each number triple corresponds either to a device file address or to a
|
||||
libburn drive number.
|
||||
Component "scsibus" indicates the translation method. Defined busses are:
|
||||
0 target is the libburn drivenumber as listed with --devices
|
||||
1 associated to device file /dev/sgN , target chooses N
|
||||
2 associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z'
|
||||
|
||||
So "1,1,0" is /dev/sg1 (resp. its /dev/sr*), "2,3,0" is /dev/hdd,
|
||||
"0,2,0" is libburn drive #2 at some unspecified device file.
|
||||
This scheme shall help to keep cdrecord-style addresses stable and exchangeable
|
||||
between users without excluding drives with unexpected device addresses.
|
||||
The numbering on bus 0 is prone to arbitrary changes caused by changes in
|
||||
drive accessability.
|
||||
Further busses may emerge as libburn evolves. "prefix" and "lun" may get
|
||||
a meaning. To stay upward compatible, use addresses as printed by -scanbus.
|
||||
|
||||
User Defined Device Address Translation
|
||||
|
||||
Some programs or users have their own ideas about the address of their burner.
|
||||
K3b 0.10 for example derives cdrecord addresses by own examination of the
|
||||
devices and not by calling cdrecord -scanbus.
|
||||
Standard mode will hopefully be fully compatible with their ideas.
|
||||
|
||||
Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
|
||||
"cdrecord" via -scanbus may be well served with option --old_pseudo_scsi_adr .
|
||||
|
||||
To direct any remaining stubborn callers to the appropriate drives, cdrskin
|
||||
allows to define device address aliases. Like
|
||||
cdrskin dev_translation=+1,0,0+/dev/sr1 \
|
||||
dev_translation=+ATA:1,0,0+/dev/sr1 \
|
||||
dev_translation=-"cd+dvd"-0,1,0 \
|
||||
...
|
||||
Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
|
||||
/dev/sr1 resp. to 0,1,0.
|
||||
The first character after "dev_translation=" defines the character which
|
||||
separates the two parts of the translation pair. (Above: "+" and "-".)
|
||||
|
||||
In K3b 0.10 it is possible to employ alternative writer programs by setting
|
||||
their full path (e.g. /usr/bin/cdrskin) in menu
|
||||
Settings:Configure K3b...:Programs:Search Path
|
||||
and to make them default in menu
|
||||
Settings:Configure K3b...:Programs:Programs:
|
||||
A suitable setting for "cdrecord" in menu
|
||||
Settings:Configure K3b...:Programs:User Parameters
|
||||
would then probably be
|
||||
-v dev_translation=+1,0,0+/dev/sr1
|
||||
You will learn from button "Show Debugging Output" after a failed burn run
|
||||
what cdrecord command was used with what address "dev=...". This address "..."
|
||||
will be the right one to replace "1,0,0" in above example.

|

|

BD-RE media need formatting before first use. cdrskin option "blank=as_needed"
|
||||
recognizes unformatted BD-RE and applies a lengthy formatting run.
|
||||
For these media, -msinfo alone would not be enough to perform appending of an
|
||||
ISO filesystem. The filesystem driver will need a hint to find the start of the
|
||||
most recent session. For example put an ISO filesystem at address 1 GB:
|
||||
mkisofs -C 0,524288 ... | \
|
||||
cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
|
||||
The superuser may then do:
|
||||
mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
|
||||
Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MiB)
|
||||
To extend a filesystem already existing at address 0
|
||||
mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
|
||||
Record the number 524288 for usage as first number with -C at the next
|
||||
extension:
|
||||
mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
|
||||
|
||||
During write operations DVD-RAM and BD-RE automatically apply Defect
|
||||
Management. This usually slows them down to half nominal speed. If drive
|
||||
and media produce flawless results anyway, then one can try to reach full
|
||||
nominal speed by option "stream_recording=on".
|
||||
In this case bad blocks are not detected during write and not even previously
|
||||
known bad blocks are avoided. So you have to make your own readability tests
|
||||
and go back to half speed as soon as the first read errors show up.
|
||||
Instead of "on" one may also set a start address for stream recording.
|
||||
Like "stream_recording=100m". This will write slowly to the first 100 MB of
|
||||
the media and accelerate when writing to higher addresses.
|
||||
|
||||
Option --grow_overwriteable_iso allows -multi (although unneeded), enables
|
||||
-msinfo and -toc, and makes blank=fast an invalidator for ISO filesystems
|
||||
on overwriteable media.

burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
|
||||
can be told to use this peculiar read mode by:

--enable-track-src-odirect

System Dependend Drive Permission Examples

only to the superuser. Linux, FreeBSD and Solaris offer quite different

First check whether some friendly system setting already allows you to

||||
Those drives of which you see address and type strings are already usable.

||||
On FreeBSD:
|
||||
-----------
|
||||
Edit /etc/devfs.rules and make sure to have these lines
|
||||
[localrules=10]
|
||||
add path 'acd*' mode 0664 group floppy
|
||||
add path 'cd*' mode 0664 group floppy
|
||||
add path 'pass*' mode 0664 group floppy
|
||||
add path 'xpt*' mode 0664 group floppy
|
||||
[localrules=5]
|
||||
add path 'pass*' mode 0664 group floppy
|
||||
add path 'cd*' mode 0664 group floppy
|
||||
add path 'xpt*' mode 0664 group floppy
|
||||
add path 'acd*' mode 0664 group floppy
|
||||
|
||||
Edit /etc/rc.conf and add the following line if missing
|
||||
devfs_system_ruleset="localrules"
|
||||
|
||||
This gets into effect by reboot or by command
|
||||
/etc/rc.d/devfs start
|
||||
|
||||
-----------
|
||||
On Solaris:
|
||||
-----------
|
||||
Run cdrskin by
|
||||
pfexec cdrskin ...arguments...
|
||||
|
||||
The following settings will make pfexec keep original UID and EUID and prevent
|
||||
most superuser powers. Be aware that you still can manipulate all device files
|
||||
if you have the file permissions for that.
|
||||
Full root privileges for cdrskin can then be aquired only by command su.
|
||||
|
||||
Edit /etc/security/exec_attr and add this line to the other "Media Backup"
|
||||
lines:
|
||||
Media Backup:solaris:cmd:::/usr/local/bin/cdrskin:privs=basic,sys_devices
|
||||
Edit /etc/user_attr and add profile "Media Backup" to the user's line:
|
||||
thomas::::profiles=Media Backup,Primary Administrator;roles=root
|
||||
See also man privileges, man exec_attr, man user_attr.
|
||||
|
||||
Then allow the group r-access to the drives
|
||||
pfexec chgrp floppy /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
|
||||
pfexec chmod g+r /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
|
||||
The last two commands have to be executed after each boot. I do not know
|
||||
the relevant device configuration files yet.

protection against possible damages. You use this on your own risk.
|

Don't blame me or other authors of libburn if anything goes wrong.
|

|
||||
Actually, in case of severe trouble, nearly always the drive and the media
|
||||
are the cause. Any mistake of the burn program is supposed to be caught
|
||||
by the drive's firmware and to lead to mere misburns.
|
||||
The worst mishaps which hit the author imposed the need to reboot the
|
||||
system because of drives gnawing endlessly on ill media. Permanent hardware
|
||||
damage did not occur in 3.5 years of development. But one never knows ...

See toplevel README for an overview of the current copyright situation in

libburnia-project.org.
|
||||
We, the copyright holders, agree on the interpretation that
|
||||
dynamical linking of our libraries constitutes "use of" and
|
||||
not "derivation from" our work in the sense of GPL, provided
|
||||
those libraries are compiled from our unaltered code.
|
||||
|
||||
Thus you may link our libraries dynamically with applications
|
||||
which are not under GPL. You may distribute our libraries and
|
||||
application tools in binary form, if you fulfill the usual
|
||||
condition of GPL to offer a copy of the source code -altered
|
||||
or unaltered- under GPL.
|
||||
|
||||
We ask you politely to use our work in open source spirit
|
||||
and with the due reference to the entire open source community.
|
||||
|
||||
If there should really arise the case where above clarification
|
||||
does not suffice to fulfill a clear and neat request in open source
|
||||
spirit that would otherwise be declined for mere formal reasons,
|
||||
only in that case we will duely consider to issue a special license
|
||||
covering only that special case.
|
||||
It is the open source idea of responsible freedom which will be
|
||||
decisive and you will have to prove that you exhausted all own
|
||||
means to qualify for GPL.
|
||||
|
||||
For now we are firmly committed to maintain one single license: GPL.

DVD advise:
|

|

For burning of DVD media other than DVD-RAM, DVD+RW, DVD+R, DVD-RW, DVD-R,
|
||||
the cdrskin project currently advises to use Andy Polyakov's dvd+rw-tools
|
||||
which despite their historic name are capable of all the media above
|
||||
and also do dual layer and even BD discs.
|
||||
|
||||
http://fy.chalmers.se/~appro/linux/DVD+RW/tools
|
||||
|
||||
They are not compatible or related to cdrecord resp. cdrecord-ProDVD
|
||||
(now obsoleted by original source cdrtools cdrecord with identical
|
||||
capabilities besides the license key).
|
||||
|
||||
A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on
|
||||
overwriteable media. This is not the same as multi-session writing of cdrskin
|
||||
with CD media, but retrieves additional information from the existing ISO
|
||||
image and finally manipulates the start sectors of this existing image.
|
||||
So for growable ISO filesystems on DVD-RAM or DVD+RW growisofs is the only
|
||||
choice, currently.
|
||||
|
||||
So, inspired by growisofs, cdrskin can offer DVD multi-session not only with
|
||||
sequential DVD-R[W] and with DVD+R [DL], but also with DVD-RAM, DVD+RW, BD-RE
|
||||
and even regular disk files or block devices other than CD/DVD writers.
|
||||
This is enabled by option --grow_overwriteable_iso.
|
||||
|
||||
The libburnia project provides an integrated ISO-9660 multi-session tool
|
||||
named [wiki:Xorriso xorriso] which tries to go one step beyond
|
||||
growisofs. It uses [wiki:Libburn libburn] , [wiki:Libisofs libisofs]
|
||||
and [wiki:Libisoburn libisoburn].
|
||||
|
||||
See [http://scdbackup.sourceforge.net/man_1_xorriso.html man xorriso].
|
||||
cdrskin can offer DVD multi-session only with sequential DVD-R[W] and with
|
||||
DVD+R.
|
||||
Associated options blank=, -multi, -msinfo and -toc are available in this case.
|
||||
Thus sequential DVD-RW behave much like large CD-RW with possibly more than 99
|
||||
tracks.

|
||||
CD-TEXT from the view of the user:
|
||||
|
||||
CD-TEXT records attributes of disc and tracks on audio CD.
|
||||
|
||||
The attributes are grouped into blocks which represent particular languages.
|
||||
Up to 8 blocks are possible.
|
||||
|
||||
There are 13 defined attribute categories, which are called Pack Types and are
|
||||
identified by a single-byte code:
|
||||
0x80 = Title
|
||||
0x81 = Names of Performers
|
||||
0x82 = Names of Songwriters
|
||||
0x83 = Names of Composers
|
||||
0x84 = Names of Arrangers
|
||||
0x85 = Messages
|
||||
0x86 = text-and-binary: Disc Identification
|
||||
0x87 = text-and-binary: Genre Identification
|
||||
0x88 = binary: Table of Content information
|
||||
0x89 = binary: Second Table of Content information
|
||||
(0x8a to 0x8c are reserved.)
|
||||
0x8d = Closed Information
|
||||
0x8e = UPC/EAN code of the album and ISRC code of each track
|
||||
0x8f = binary: Size Information of the Block
|
||||
|
||||
Some of these categories apply to the whole disc only:
|
||||
0x86, 0x87, 0x88, 0x89, 0x8d
|
||||
Some have to be additionally attributed to each track, if they are present for
|
||||
the whole disc:
|
||||
0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x8e
|
||||
One describes the overall content of a block and in part of all other blocks:
|
||||
0x8f
|
||||
|
||||
The total size of a block's attribute set is restricted by the fact that it
|
||||
has to be stored in at most 253 records with 12 bytes of payload. These records
|
||||
are called Text Packs.
|
||||
A shortcut for repeated identical track texts is provided, so that a text
|
||||
that is identical to the one of the previous track occupies only 2 or 4 bytes.
|
||||
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
Content specification of particular pack types:
|
||||
|
||||
Pack types 0x80 to 0x85 and 0x8e contain 0-terminated cleartext. If double byte
|
||||
characters are used, then two 0-bytes terminate the cleartext.
|
||||
The meaning of 0x80 to 0x85 should be clear by above list. They are encoded
|
||||
according to the Character Code of their block. Either as ISO-8859-1 single
|
||||
byte characters, or as 7-bit ASCII single byte characters, or as MS-JIS double
|
||||
byte characters.
|
||||
More info to 0x8e is given below.
|
||||
|
||||
Pack type 0x86 (Disc Identification) is documented by Sony as "Catalog Number:
|
||||
(use ASCII Code) Catalog Number of the album". So it is not really binary
|
||||
but might be non-printable, and should contain only bytes with bit7 = 0.
|
||||
|
||||
Pack type 0x87 contains 2 binary bytes, followed by 0-terminated cleartext.
|
||||
The two binary bytes form a big-endian index to the following list.
|
||||
0x0000 = "Not Used" (Sony prescribes to use this if no genre applies)
|
||||
0x0001 = "Not Defined"
|
||||
0x0002 = "Adult Contemporary"
|
||||
0x0003 = "Alternative Rock"
|
||||
0x0004 = "Childrens Music"
|
||||
0x0005 = "Classical"
|
||||
0x0006 = "Contemporary Christian"
|
||||
0x0007 = "Country"
|
||||
0x0008 = "Dance"
|
||||
0x0009 = "Easy Listening"
|
||||
0x000a = "Erotic"
|
||||
0x000b = "Folk"
|
||||
0x000c = "Gospel"
|
||||
0x000d = "Hip Hop"
|
||||
0x000e = "Jazz"
|
||||
0x000f = "Latin"
|
||||
0x0010 = "Musical"
|
||||
0x0011 = "New Age"
|
||||
0x0012 = "Opera"
|
||||
0x0013 = "Operetta"
|
||||
0x0014 = "Pop Music"
|
||||
0x0015 = "Rap"
|
||||
0x0016 = "Reggae"
|
||||
0x0017 = "Rock Music"
|
||||
0x0018 = "Rhythm & Blues"
|
||||
0x0019 = "Sound Effects"
|
||||
0x001a = "Spoken Word"
|
||||
0x001b = "World Music"
|
||||
Sony documents the cleartext part as "Genre information that would supplement
|
||||
the Genre Code, such as 'USA Rock music in the 60s'". Always ASCII encoded.
|
||||
|
||||
Pack type 0x88 records information from the CD's Table of Content, as of
|
||||
READ PMA/TOC/ATIP Format 0010b (mmc3r10g.pdf, table 237 TOC Track Descriptor
|
||||
Format, Q Sub-channel).
|
||||
See below, Format of a CD-TEXT packs array, for more details about the content
|
||||
of pack type 0x88.
|
||||
|
||||
Pack type 0x89 is yet quite unclear. It might be a representation of Playback
|
||||
Skip Interval, Mode-5 Q sub-channel, POINT 01 to 40 (mmc3r10g.pdf 4.2.3.6.3).
|
||||
If so, then this seems not to apply to write type SAO, because the CUE SHEET
|
||||
format offers no way to express Mode-5 Q.
|
||||
See below, Format of a CD-TEXT packs array, for an example of this pack type.
|
||||
|
||||
Pack type 0x8d is documented by Sony as "Closed Information: (use 8859-1 Code)
|
||||
Any information can be recorded on disc as memorandum. Information in this
|
||||
field will not be read by CD TEXT players available to the public."
|
||||
Always ISO-8859-1 encoded.
|
||||
|
||||
Pack type 0x8e is documented by Sony as "UPC/EAN Code (POS Code) of the album.
|
||||
This field typically consists of 13 characters." Always ASCII encoded.
|
||||
It applies to tracks as "ISRC code [which] typically consists of 12 characters"
|
||||
and is always ISO-8859-1 encoded.
|
||||
MMC calls these information entities Media Catalog Number and ISRC.
|
||||
The catalog number consists of 13 decimal digits.
|
||||
ISRC consists of 12 characters: 2 country code [0-9A-Z], 3 owner code [0-9A-Z],
|
||||
2 year digits (00 to 99), 5 serial number digits (00000 to 99999).
|
||||
|
||||
Pack type 0x8f summarizes the whole list of text packs of a block.
|
||||
See below, Format of a CD-TEXT packs array, for details.
|
||||
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
Format of a CD-TEXT packs array:
|
||||
|
||||
The attributes are represented on CD as Text Packs in the sub-channel of
|
||||
the Lead-in of the disc. See doc/cookbook.txt for a description how to write
|
||||
the readily formatted CD-TEXT pack array to CD, and how to read CD-TEXT packs
|
||||
from CD.
|
||||
|
||||
The format is explained in part in MMC-3 (mmc3r10g.pdf, Annex J) and in part by
|
||||
the documentation in Sony's cdtext.zip :
|
||||
|
||||
Each pack consists of a 4-byte header, 12 bytes of payload, and 2 bytes of CRC.
|
||||
|
||||
The first byte of each pack tells the pack type. See above for a list of types.
|
||||
|
||||
The second byte tells the track number to which the first text piece in
|
||||
a pack is associated. Number 0 means the whole album. Higher numbers are
|
||||
valid for types 0x80 to 0x85, and 0x8e. With these types, there should be
|
||||
one text for the disc and one for each track.
|
||||
With types 0x88 and 0x89, the second byte bears a track number, too.
|
||||
With type 0x8f, the second byte counts the record parts from 0 to 2.
|
||||
|
||||
The third byte is a sequential counter.
|
||||
|
||||
The fourth byte is the Block Number and Character Position Indicator.
|
||||
It consists of three bit fields:
|
||||
bit7 = Double Bytes Character Code (0= single byte characters)
|
||||
bit4-6 = Block Number (groups text packs in language blocks)
|
||||
bit0-3 = Character position. Either the number of characters which
|
||||
the current text inherited from the previous pack, or
|
||||
15 if the current text started before the previous pack.
|
||||
|
||||
The 12 payload bytes contain pieces of 0-terminated texts or binary data.
|
||||
A text may span over several packs. Unused characters in a pack are used for
|
||||
the next text of the same pack type. If no text of the same type follows,
|
||||
then the remaining text bytes are set to 0.
|
||||
|
||||
The CRC algorithm uses divisor 0x11021. The resulting 16-bit residue of the
|
||||
polynomial division gets inverted and written as big-endian number to bytes
|
||||
16 and 17 of the pack.
|
||||
|
||||
|
||||
The text packs are grouped in up to 8 blocks of at most 256 packs. Each block
|
||||
is in charge for one language. Sequence numbers of each block are counted
|
||||
separately. All packs of block 0 come before the packs of block 1.
|
||||
|
||||
The limitation of block number and sequence numbers imply that there are at
|
||||
most 2048 text packs possible. (READ TOC/PMA/ATIP could retrieve 3640 packs,
|
||||
as it is limited to 64 kB - 2.)
|
||||
|
||||
|
||||
If a text of a track (pack types 0x80 to 0x85 and 0x8e) repeats identically
|
||||
for the next track, then it may be represented by a TAB character (ASCII 9)
|
||||
for single byte texts, resp. two TAB characters for double byte texts.
|
||||
(This should be used because 256 * 12 bytes is few space for 99 tracks.)
|
||||
|
||||
The two binary bytes of pack type 0x87 are written to the first 0x87 pack of
|
||||
a block. They may or may not be repeated at the start of the follow-up packs
|
||||
of type 0x87.
|
||||
|
||||
The first pack of type 0x88 in a block records in its payload bytes:
|
||||
0 : PMIN of POINT A1 = First Track Number
|
||||
1 : PMIN of POINT A2 = Last Track Number
|
||||
2 : unknown, 0 in Sony example
|
||||
3 : PMIN of POINT A2 = Start position of Lead-Out
|
||||
4 : PSEC of POINT A2 = Start position of Lead-Out
|
||||
5 : PFRAME of POINT A2 = Start position of Lead-Out
|
||||
6 to 11 : unknown, 0 in Sony example
|
||||
The following packs record PMIN, PSEC, PFRAME of the POINTs between the
|
||||
lowest track number (min 01h) and the highest track number (max 63h).
|
||||
The payload of the last pack is padded by 0s.
|
||||

|
||||

|
||||
A1 14
|

|

|
||||
Pack type 0x89 is yet quite unclear. Especially what the information shall
|
||||
mean to the user of the CD. The time points in the Sony example are in the
|
||||
time range of the tracks numbers that are given before the time points:
|
||||
01 02:41:48 01 02:52:58
|
||||
06 23:14:25 06 23:29:60
|
||||
07 28:30:39 07 28:42:30
|
||||
13 55:13:26 13 55:31:50
|
||||
yields
|
||||
89 01 28 00 01 04 00 00 00 00 02 29 30 02 34 3a f3 0c
|
||||
89 06 29 00 02 04 00 00 00 00 17 0e 19 17 1d 3c 73 92
|
||||

|
||||
89 0d 2b 00 04 04 00 00 00 00 37 0d 1a 37 1f 32 0b 62
|
||||
The track numbers are stored in the track number byte of the packs. The two
|
||||
time points are stored in byte 6 to 11 of the payload. Byte 0 of the payload
|
||||
seems to be a sequential counter. Byte 1 always 4 ? Byte 2 to 5 always 0 ?
|
||||
|
||||
Pack type 0x8f summarizes the whole list of text packs of a block.
|
||||
So there is one group of three 0x8f packs per block.
|
||||
Nevertheless each 0x8f group tells the highest sequence number and the
|
||||
language code of all blocks.
|
||||
The payload bytes of three 0x8f packs form a 36 byte record. The track number
|
||||
bytes of the three packs have the values 0, 1, 2.
|
||||
Byte :
|
||||
0 : Character code for pack types 0x80 to 0x85:
|
||||
0x00 = ISO-8859-1
|
||||
0x01 = 7 bit ASCII
|
||||
0x80 = MS-JIS (japanese Kanji, double byte characters)
|
||||
1 : Number of first track
|
||||
2 : Number of last track
|
||||
3 : libcdio source states: "cd-text information copyright byte"
|
||||
Probably 3 means "copyrighted", 0 means "not copyrighted".
|
||||
4 - 19 : Pack count of the various types 0x80 to 0x8f.
|
||||
Byte number N tells the count of packs of type 0x80 + (N - 4).
|
||||
I.e. the first byte in this field of 16 counts packs of type 0x80.
|
||||
20 - 27 : Highest sequence byte number of blocks 0 to 7.
|
||||
28 - 36 : Language code for blocks 0 to 7 (tech3264.pdf appendix 3)
|
||||
Not all of these Codes have ever been seen with CD-TEXT, though.

Overview of libburn API calls for CD-TEXT (see libburn/libburn.h for details):
|
||||
|
||||
libburn can retrieve the set of text packs from a CD:
|
||||
|
||||
int burn_disc_get_leadin_text(struct burn_drive *d,
|
||||
unsigned char **text_packs, int *num_packs,
|
||||
int flag);
|
||||
|
||||
|
||||
It can write a text pack set with a CD SAO session.
|
||||
|
||||
This set may be attached as array of readily formatted text packs by:
|
||||
|
||||
int burn_write_opts_set_leadin_text(struct burn_write_opts *opts,
|
||||
unsigned char *text_packs,
|
||||
int num_packs, int flag);
|
||||
|
||||
The array may be read from a file by
|
||||
|
||||
int burn_cdtext_from_packfile(char *path, unsigned char **text_packs,
|
||||
int *num_packs, int flag);
|
||||
|
||||
|
||||
Alternatively the pack set may be defined by attaching CD-TEXT attributes
|
||||
to burn_session and burn_track:
|
||||
|
||||
int burn_session_set_cdtext_par(struct burn_session *s,
|
||||
int char_codes[8], int copyrights[8],
|
||||
int languages[8], int flag);
|
||||
|
||||
int burn_session_set_cdtext(struct burn_session *s, int block,
|
||||
int pack_type, char *pack_type_name,
|
||||
unsigned char *payload, int length, int flag);
|
||||
|
||||
int burn_track_set_cdtext(struct burn_track *t, int block,
|
||||
int pack_type, char *pack_type_name,
|
||||
unsigned char *payload, int length, int flag);
|
||||
|
||||
Macros list the texts for genre and language codes:
|
||||
|
||||
BURN_CDTEXT_LANGUAGES_0X00

There is a reader for Sony Input Sheet Version 0.7T:
|
||||
|
||||
int burn_session_input_sheet_v07t(struct burn_session *session,
|
||||
char *path, int block, int flag);
|
||||
|
||||
CD-TEXT can be read from a CDRWIN cue sheet file which defines the tracks
|
||||
of a session
|
||||
|
||||
int burn_session_by_cue_file(struct burn_session *session,
|
||||
char *path, int fifo_size, struct burn_source **fifo,
|
||||
unsigned char **text_packs, int *num_packs, int flag);
|
||||
|
||||
|
||||
The session and track attributes can then be converted into an array of
|
||||
text packs by:
|
||||
|
||||
int burn_cdtext_from_session(struct burn_session *s,
|
||||
unsigned char **text_packs, int *num_packs,
|
||||
int flag);
|
||||
|
||||
or they can be written as array of text packs to CD when burning begins and
|
||||
no array of pre-formatted packs was attached to the write options by
|
||||
burn_write_opts_set_leadin_text().
|
||||
|
||||
There are calls for inspecting the attached attributes:
|
||||
|
||||
int burn_session_get_cdtext_par(struct burn_session *s,
|
||||
int char_codes[8], int copyrights[8],
|
||||
int block_languages[8], int flag);
|
||||
|
||||
int burn_session_get_cdtext(struct burn_session *s, int block,
|
||||
int pack_type, char *pack_type_name,
|
||||
unsigned char **payload, int *length, int flag);
|
||||
|
||||
int burn_track_get_cdtext(struct burn_track *t, int block,
|
||||
int pack_type, char *pack_type_name,
|
||||
unsigned char **payload, int *length, int flag);
|
||||
|
||||
and for removing attached attributes:
|
||||
|
||||
int burn_session_dispose_cdtext(struct burn_session *s, int block);
|
||||
|
||||
int burn_track_dispose_cdtext(struct burn_track *t, int block);
|
||||
|
||||
|
||||
UPC/EAN and ISRC not only affect CD-TEXT but also information that is written
|
||||
along with the tracks in Q sub-channel. These can be influenced by
|
||||
burn_session_input_sheet_v07t(), burn_session_by_cue_file() and by
|
||||
|
||||
void burn_write_opts_set_mediacatalog(struct burn_write_opts *opts,
|
||||
unsigned char mediacatalog[13]);
|
||||
|
||||
void burn_write_opts_set_has_mediacatalog(struct burn_write_opts *opts,
|
||||
int has_mediacatalog);
|
||||
|

void burn_track_set_isrc(struct burn_track *t, char *country, char *owner,
|

unsigned char year, unsigned int serial);
|
||||
|

Sony Text File Format (Input Sheet Version 0.7T):
|
||||
|
||||
This text file format provides comprehensive means to define the text
|
||||
attributes of session and tracks for a single block. More than one
|
||||
such file has to be read to form an attribute set with multiple blocks.
|
||||
|
||||
The information is given by text lines of the following form:
|
||||
purpose specifier [whitespace] = [whitespace] content text
|
||||
[whitespace] is zero or more ASCII 32 (space) or ASCII 9 (tab) characters.
|
||||
The purpose specifier tells the meaning of the content text.
|
||||
Empty content text does not cause a CD-TEXT attribute to be attached.
|
||||
|
||||
The following purpose specifiers apply to the session as a whole:
|
||||
Specifier = Meaning

The following purpose specifiers accept byte values of the form 0xXY.
|
||||
Text Code , Language Code , Genre Code , Text Data Copy Protection
|
||||
E.g. to indicate MS-JIS character code (of which the exact name is unknown):
|
||||
Text Code = 0x80
|
||||
Genre Code is settable by 0xXY or 0xXYZT or 0xXY 0xZT.
|
||||
Genre Code = 0x001b
|
||||
|
||||
Purpose specifiers which have the meaning "Content of pack type 0xXY"
|
||||
may be replaced by the pack type codes. E.g.:
|
||||
0x80 = Session content of pack type 0x80
|
||||
Track 02 0x80 = Track content of pack type 0x80 for track 2.
|
||||
Applicable are pack types 0x80 to 0x86, 0x8d, 0x8e.
|
||||
|
||||
Text Code may be specified only once. It gets speficied to "ISO-8850-1"
|
||||
automatically as soon as content is defined which depends on the text
|
||||
encoding of the block. I.e with pack types 0x80 to 0x85.
|
||||
|
||||
If a track attribute is set, but the corresponding session attribute is not
|
||||
defined or defined with empty text, then the session attribute gets attached
|
||||
as empty test. (Normally empty content is ignored.)

@section intro Introduction
|
||||
|
||||
Libburnia is an open-source project for reading, mastering and writing
|
||||
optical discs. This page is about its capability to handle optical media.
|
||||
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW,
|
||||
DVD-R, DVD-R/DL, BD-R, BD-RE.
|
||||
optical discs.
|
||||
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD-RW, DVD-R.
|
||||
|
||||
Our scope is currently Linux 2.4 and 2.6, or FreeBSD, or Solaris . For ports
|
||||
to other systems we would need : login on a development machine resp.
|
||||
an OS ithat is installable on an AMD 64-bit PC, advise from a system person
|
||||
about the equivalent of Linux sg or FreeBSD CAM, volunteers for testing of
|
||||
realistic use cases.
|
||||
Not supported yet are dual layer media, HD-DVD, BD (blue ray). Testers for
|
||||
dual layer DVD+/-R are wanted, though.
|
||||
|
||||
libburn is the library by which preformatted data get onto optical media.
|
||||
Its code is independent of cdrecord. Its DVD capabilities are learned from
|
||||
studying the code of dvd+rw-tools and MMC-5 specs. No code but only the pure
|
||||
SCSI knowledge has been taken from dvd+rw-tools, though.
|
||||
The project comprises of several more or less interdependent parts which
|
||||
together strive to be a usable foundation for application development.
|
||||
These are libraries, language bindings, and middleware binaries which emulate
|
||||
classical (and valuable) Linux tools.
|
||||
|
||||
cdrskin is a limited cdrecord compatibility wrapper for libburn.
|
||||
cdrecord is a powerful GPL'ed burn program included in Joerg Schilling's
|
||||
cdrtools. cdrskin strives to be a second source for the services traditionally
|
||||
provided by cdrecord. Additionally it provides libburn's DVD/BD capabilities,
|
||||
where only -sao is compatible with cdrecord.
|
||||
cdrskin does not contain any bytes copied from cdrecord's sources.
|
||||
Many bytes have been copied from the message output of cdrecord runs, though.
|
||||
See cdrskin/README for more.
|
||||
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
|
||||
we would need : login on a development machine resp. a live OS on CD or DVD,
|
||||
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
|
||||
volunteers for testing of realistic use cases.
|
||||
|
||||
The burn API example of libburn is named test/libburner.c . The API for media
|
||||
information inquiry is demonstrated in test/telltoc.c .
|
||||
Explore these examples if you look for inspiration.
|
||||
We have a workable code base for burning data and audio CDs and many DVD types.
|
||||
The burn API is quite comprehensively documented and can be used to build a
|
||||
presentable application.
|
||||
We have a functional binary which emulates the core use cases of cdrecord in
|
||||
order to prove that usability, and in order to allow you to explore libburn's
|
||||
scope by help of existing cdrecord frontends.

@subsection components The project components (list subject to growth, hopefully):
|
||||
|
||||
- libburn is the library by which preformatted data get onto optical media.
|
||||
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
|
||||
/dev/srM or /dev/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation. Its code is
|
||||
independent of cdrecord. Its DVD capabilities are learned from
|
||||
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
|
||||
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
|
||||
|
||||
- libisofs is the library to pack up hard disk files and directories into a
|
||||
ISO 9660 disk image. This may then be brought to CD via libburn.
|
||||
libisofs is to be the foundation of our upcoming mkisofs emulation.
|
||||
|
||||
- cdrskin is a limited cdrecord compatibility wrapper for libburn.
|
||||
cdrecord is a powerful GPL'ed burn program included in Joerg
|
||||

|
||||
runs, though.
|
||||
See cdrskin/README for more.
|
||||
|
||||
- "test" is a collection of application gestures and examples given by the
|
||||
authors of the library features. The burn API example of libburn
|
||||
is named test/libburner.c . The API for media information inquiry is
|
||||
demonstrated in test/telltoc.c .
|
||||
Explore these examples if you look for inspiration.
|
||||
|
||||
We plan to be a responsive upstream. Bear with us.

@section using Using the libraries
|
||||
|
||||
Our build system is based on autotools.
|
||||
User experience tells us that you will need at least autotools version 1.7.

To build libburn and its subprojects it should be sufficient to go into

languages and development tools.

INDEX is a subaddress within tracks. INDEX 1 is mandatory and marks the start
|

of the payload area of a track. The range between INDEX 0 and 1 is called
|

pre-gap. It should contain zeros if it exists. Further cue sheet entries with

DVD-RAM and BD-RE formatting :

Although DVD-RAM usually are sold formatted, there may still arise the wish
|
||||
to adjust formatting.
|
||||
BD-RE are sold unformatted and need to be formatted prior to usage.
|
||||
|
||||
Two format types are relevant for DVD-RAM : 00h and 01h.
|
||||
00h offers the default size format and usually a maximum payload size format.
|
||||
Even with that maximum size payload there is hardware defect management.
|
||||
(mmc5r03c.pdf 6.5.4.2.1.2)
|
||||
01h allows to convert payload capacity into spare blocks for defect
|
||||
managment. There is no way to increase payload capacity by format 01h.
|
||||
(mmc5r03c.pdf 6.5.4.2.2.1)
|
||||
|
||||
With BD-RE there are three format types : 00h, 30h and 31h.
|
||||
00h offers the default size format. This may be the only fast formatting
|
||||
mode that is offered by the drive.

30h offers several sizes with defect management. Usually there are three
|
||||
sizes given: #1: default size, #2: maximum spare area, #3: minimal spare.
|
||||
One may demand any spare size between maximum and minimum. There may be quick
|
||||
certification and full certification. See feature 0023h.
|
||||
31h offers a single size and disables defect management. This has the side
|
||||
effect to speed up writing to nominal speed.
|
||||
(mmc5r03c.pdf 6.5.4.2.15, 6.24.3.3, Table 472)
|
||||
|
||||
Only format sizes from the list of format descriptors are permissible
|
||||
for DVD-RAM. The format list can be obtained by 23h READ FORMAT CAPACITIES.
|
||||
It also includes a description of the current formatting state.
|
||||
(mmc5r03c.pdf 6.24, 6.24.3.2, 6.24.3.3)
|
||||
|
||||
Formatting is done by command 04h FORMAT UNIT. Its data payload consists
|
||||
of a Format List Header and a Format Descriptor. It is advisable to set
|
||||
the Immed bit and the FOV bit in header byte number 1. The descriptor should
|
||||
be a copy of a descriptor from 23h READ FORMAT CAPACITIES.
|
||||
(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
|
||||
With nearly all formats Sub-type should be set to 0. But with BD-RE formats
|
||||
30h and 31h the Sub-type selects the certification mode.
|
||||
Usable with 30h seem 10b Full Certification and 11b Quick Certification.
|
||||
Usable with 31h seem also 00b Quick Reformat and 01b No Certification.
|
||||
(mmc5r03c.pdf 6.5.4.2.15.1)
|
||||
|
||||
Other format types have their certification intensity controlled by
|
||||
a pair of bits: CmpList and DCRT.
|
||||
CmpList resides in CDB byte 1 as bit 3. DCRT resides in the payload byte 1
|
||||
as bit 5. Both together should request a quick size change without lengthy
|
||||
certification but maintaining the list of known defects.
|
||||
(mmc5r03c.pdf 6.5, table 249, 6.5.3.2)
|
||||
With DVD-RAM on my PHILIPS SPD3300L drive they prevent any format size
|
||||
change though. The TSSTcorp SH-S203B works properly.
|
||||
With BD-RE format 00h, the default is specified to be Quick Reformat,
|
||||
and with 00h in general certification can only be disabled not enabled.

||||

|
||||
DVD-RAM and BD-RE tuning :
|
||||
|
||||
A special aspect of DVD-RAM and BD-RE is their low speed with write operations,
|
||||
which usually is only half than the nominal speed of media and drive.
|
||||
This is blamed to the automatic checkreading which happens for managing
|
||||
eventual defects.
|
||||
|
||||
Defect management of BD-RE can be disabled by format type 31h. See above.
|
||||
There is no drive known yet which would apply command 2Ah WRITE10 to DVD-RAM
|
||||
with full speed.
|
||||
|
||||
The only known way to get full speed from DVD-RAM or BD-RE with enabled defect
|
||||
management is the use of AAh WRITE12 with Streaming Bit set to 1.
|
||||
(mmc5r03c.pdf 6.45)
|
||||
With some DVD-RAM drives this fails if a write buffer is not full 32 kB.
|
||||
With the tested BD-RE one must write full 64 kB buffers, or else writing
|
||||
might not get into effect at all.
|
||||
|
||||
Although it seems not optimal, this is specified not only to disable the
|
||||
cumbersome checkread but also to ignore known defects and to write data
|
||||
to these defective addresses.
|
||||
(mmc5r03c.pdf 4.8.5)
|
||||
So the speed-up is only advisable as long as the media are free of
|
||||
incorrectable errors.
|
||||
|
||||
Caveat:
|
||||
MMC-5 does not guarantee AAh WRITE12 to work on DVD-RAM or BD-RE at all.
|
||||
None of the features of profiles 0012h and 0043h promises the existence of
|
||||
AAh WRITE12.
|
||||
(mmc5r03c.pdf 5.4.13, 6.45)
|
||||
Nevertheless it worked on all tested drives if proper alignment and block
|
||||
size was observed.

|
||||
ISO 9660 multi-session emulation on overwriteable media :
|
||||
|
||||
Overwriteable media provide a single overwriteable track which may grow up to
|
||||
the full media capacity. There is no builtin table-of-content which records
|
||||
the history of write sessions.
|
||||
mount -t iso9660 will use sbsector=0 as default.
|
||||
The term "superblock" shall depict the first 64 KiB after the sbsector address.
|
||||
|
||||
ISO 9660 multi-session depends on typical TOC information in two ways:
|
||||
It needs the superblock address MSC1 of the most recently recorded session and
|
||||
it needs the Next Writeable Address NWA for which to prepare the adress offset.
|
||||
|
||||
The following is learned from growisofs and from ECMA-119:
|
||||
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-119.pdf
|
||||
|
||||
ISO 9660 filesystems provide information about the number of sectors which
|
||||
is also the lowest unused block address and thus a suitable NWA.
|
||||
This block address is stored in the Primary Volume Descriptor which is supposed
|
||||
to be stored in block 16 (eventually relative to MSC1).
|
||||
The bytes 0 to 5 of a PVD block are
|
||||
0x01 'C' 'D' '0' '0' '1'
|
||||
The sector count can then be read from byte 80 to 83
|
||||
sectors= pvd[80] | (pvd[81] << 8) | (pvd[82] << 16) | (pvd[83] << 24);
|
||||
(Ecma-119.pdf 8.4)
|
||||
To support CD, DVD and BD media alike, it is advisable to round the NWA
|
||||
to the next multiple of 32 (= 64 KiB).
|
||||
|
||||
So one can use 0 as MSC1 and prepare a new ISO session for the computed NWA.
|
||||
After writing the session it is necessary to copy the PVD from session start
|
||||
plus 16 to LBA 16 and to adjust it to its new location.
|
||||
The minimal change would be to update the number of image sectors.
|
||||
It is stored in both notations LSB and MSB:
|
||||
for(i= 0; i < 4; i++)
|
||||
pvd[87 - i]= pvd[80 + i]= (sectors >> (8 * i)) & 0xff;
|
||||
|
||||
cdrskin --grow_overwriteable_iso not only patches the sector fields of the
|
||||
PVD block but also the blocks up to LBA 31 which begin with
|
||||
0xff 'C' 'D' '0' '0' '1'
|
||||
libisoburn submits 64 KiB data buffer to libisofs before image generation and
|
||||
afterwards writes these 64 KiB as new superblock to LBA 0.
|
||||
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
ISO 9660 based TOC emulation on overwriteable media :
|
||||
|
||||
Above method of multi-session emulation yields a single session image after
|
||||
each add-on session. No reliable session history can be read because the
|
||||
sector size of the existing session gets overwritten by the new one.
|
||||
A TOC with session history is nevertheless desirable with incremental backups
|
||||
in order to access older backup states by mounting older superblocks at the
|
||||
start addresses of older sessions.
|
||||
|
||||
All usual ISO 9660 formatter programs write a complete superblock to the
|
||||
start of each session.
|
||||
With a uniform NWA rounding rule it is possible to compute the address of
|
||||
superblock N+1 as the NWA after session N. The only problem is N=1
|
||||
because it gets overwritten by later sessions.
|
||||
|
||||
libisoburn preserves the information of session 1 by writing the first session
|
||||
to LBA 32 rather than LBA 0. Afterwards it writes the overall superblock to
|
||||
LBA 0 (up to 31).
|
||||
So with all further add-on sessions the superblock at LBA 0 will enclose the
|
||||
overall image, while the superblocks of the sessions form a chain beginning
|
||||
at LBA 32. Each session superblock points to the next one by its sector count
|
||||
rounded up to 32. The chain end is marked by the overall image size.
|
||||
This chain gives the start addresses of sessions. The sector count minus start
|
||||
address gives the size of a particular session. ECMA-119 explains how to
|
||||
retrieve more info from the PVD (e.g. the volume id).
|
||||
|
||||
See also the multi-session example in libisofs/doc/checksums.txt.

|
||||
SRM Formatting:
|
||||
|
||||
Despite being write-once media BD-R can optionally carry some formatting.
|
||||
|
||||
SRM has a disc structure model with tracks and sessions.
|
||||
Several tracks may be open at the same time, each having its own NWA.
|
||||
(mmc5r03c.pdf 4.5.3.5.2.2)
|
||||
This structure is formatted onto blank media automatically as soon as the
|
||||
first serious write attempt occurs.
|
||||
(mmc5r03c.pdf 4.5.3.5)
|
||||
Before such a write attempt, blank media may be explicitely formatted with
|
||||
spares, which provide defect management.
|
||||
(mmc5r03c.pdf 4.5.3.5.3)
|
||||
Tracks get created from other tracks via RESERVE TRACK splitting.
|
||||
(mmc5r03c.pdf 4.5.3.5.2.5)
|
||||
|
||||
On top of defect management there may be Pseudo-OverWrite SRM+POW, a costly
|
||||
way to write several times to the same LBA. See below.
|
||||
Fully sequential states are called SRM-POW.
|
||||
(mmc5r03c.pdf 4.5.3.5.4)
|
||||
|
||||
Explicite formatting is done by 04h FORMAT UNIT. Its data payload consists
|
||||
of a Format List Header and a Format Descriptor. It is advisable to set
|
||||
the Immed bit and the FOV bit in header byte number 1. The descriptor should
|
||||
be a copy of a descriptor from 23h READ FORMAT CAPACITIES but the size may be
|
||||
adjusted within a certain range.
|
||||
(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
|
||||
|
||||
Format type 00h creates SRM layouts with a default number of spares (or
|
||||
eventually RRM) chosen by the format sub-type:
|
||||
00b = SRM with support for POW
|
||||
01b = SRM without POW (but with some spares for defect management)
|
||||
10b = (RRM)
|
||||
(mmc5r03c.pdf 6.5.4.2.1.6)
|
||||
|
||||
Format type 32h uses the same sub-types but allows to allocate non-default
|
||||
amounts of spares. Similar to BD-RE format 31h, three format descriptors are
|
||||
offered: #1: default size, #2: maximum spare area, #3: minimal spare.
|
||||
The size may be chosen within that range.
|
||||
|
||||
The sense behind the Type Dependent Parameters is obscure
|
||||
to me. Best will be to set ISA_V and TDMA_V to 0.

|
||||
Writing a session in SRM:
|
||||
|
||||
The procedure and constraints for writing BD-R SRM-POW are very similar to
|
||||
DVD+R. libburn flatly re-uses its DVD+R code except the Close Function for
|
||||
finalizing a disc.
|
||||
|
||||
In short:
|
||||
If all written sessions are closed, then there is exactly one NWA.
|
||||
In the beginning there is an empty session and track. A new track can be
|
||||
written either with pre-announced size (by RESERVE TRACK) or open-end by
|
||||
simply starting to write to the NWA. When done the track gets closed by
|
||||
close function 001b. Then either session or disc gets closed depending on
|
||||
the Close Function used:
|
||||
- Close Function 010b closes the session and keeps the media appendable
|
||||
(same as with DVD+R)
|
||||
- Close Function 110b finalizes the media and makes it read-only.
|
||||
(differs from libburn DVD+R procedure which uses 101b)
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
Pseudo-OverWrite POW: (no used yet by libburn)
|
||||
|
||||
This enhancement of SRM emulates overwriting of existing data blocks.
|
||||
(mmc5r03c.pdf 4.5.3.5.4)
|
||||
|
||||
POW establishes a virtual vLBA space on top of the real address space rLBA.
|
||||
All read and write commands deal with vLBA. It seems that track NWAs are
|
||||
assumed to be identical in vLBA space and in rLBA space.
|
||||
It is not clear whether one may write to vLBA blocks which are neither written
|
||||
yet nor at one of the track NWAs. Probably not, or else one could make NWAs run
|
||||
into vLBAs which are associated with older rLBAs.
|
||||
|
||||
Replacing invalidated blocks consumes addresses in rLBA space at the NWA of
|
||||
some track. I.e. no spares are consumed by POW. Nevertheless it is costly by
|
||||
a special map called Orphanage. It covers rLBA which have been consumed
|
||||
by differing vLBAs. It never shrinks and can grow with each write to remapped
|
||||
addresses.
|
||||
To avoid heavy Orphanage growth it is advised to write mostly to vLBA which
|
||||
still coincide with their rLBA. E.g. those addresses which have neither been
|
||||
written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions
|
||||
at the NWA of a sufficiently sized track.

|

|

Used in libburn for raw write modes in sector.c.
|

There is also disabled code in read.c which would use it.
|
||||
|
||||
ts B11222:
|
||||
The same algorithm is prescribed for CD-TEXT in MMC-3 Annex J.
|
||||
"CRC Field consists of 2 bytes. Initiator system may use these bytes
|
||||
to check errors in the Pack. The polynomial is x^16 + x^12 + x^5 + 1.
|
||||
All bits shall be inverted."
|
||||
|
||||
libburn/cdtext.c uses a simple bit shifting function : crc_11021()
|
||||
|
||||
|
||||
ts B20211:
|
||||
Discussion why both are equivalent in respect to their result:
|
||||
|
||||
Both map the bits of the given bytes to a polynomial over the finite field
|
||||
of two elements "GF(2)". If bytes 0 .. M are given, then bit n of byte m
|
||||
is mapped to the coefficient of x exponent (n + ((M - m) * 8) + 16).
|
||||
I.e. they translate the bits into a polynomial with the highest bit
|
||||
becomming the coefficient of the highest power of x. Then this polynomial
|
||||
is multiplied by (x exp 16).
|
||||
|
||||
The set of all such polynomials forms a commutative ring. Its addition
|
||||
corresponds to bitwise exclusive or. Addition and subtraction are identical.
|
||||
Multiplication with polynomials of only one single non-zero coefficient
|
||||
corresponds to leftward bit shifting by the exponent of that coefficient.
|
||||
The same rules apply as with elementary school arithmetics on integer
|
||||
numbers, but with surprising results due to the finite nature of the
|
||||
coefficient number space.
|
||||
Note that multiplication is _not_ an iteration of addition here.
|
||||
|
||||
Function crc_11021() performs a division with residue by the euclidian
|
||||
algorithm. I.e. it splits polynomial d into quotient q(d) and residue r(d)
|
||||
in respect to the polynomial p = x exp 16 + x exp 12 + x exp 5 + x exp 0
|
||||
d = p * q(d) + r(d)
|
||||
where r(d) is of a polynomial degree lower than p, i.e. only x exp 15
|
||||
or lower have non-zero coefficients.
|
||||
The checksum crc(D) is derived by reverse mapping (r(d) * (x exp 16)).
|
||||
I.e. by mapping the coefficient of (x exp n) to bit n of the 16 bit word
|
||||
crc(D).
|
||||
The function result is the bit-wise complement of crc(D).
|
||||
|
||||
Function crc_ccitt uses a table ccitt_table of r(d) values for the
|
||||
polynomials d which represent the single byte values 0x00 to 0xff.
|
||||
It computes r(d) by computing the residues of an iteratively expanded
|
||||
polynomial. The expansion of the processed byte string A by the next byte B
|
||||
from the input byte string happens by shifting the string 8 bits to the
|
||||
left, and by oring B onto bits 0 to 7.
|
||||
In the space of polynomials, the already processed polynomial "a" (image of
|
||||
byte string A) gets expanded by polynomial b (the image of byte B) like this
|
||||
a * X + b
|
||||
where X is (x exp 8), i.e. the single coefficient polynomial of degree 8.
|
||||
|
||||
The following argumentation uses algebra with commutative, associative
|
||||
and distributive laws.
|
||||
Valid especially with polynomials is this rule:
|
||||
(1): r(a + b) = r(a) + r(b)
|
||||
because r(a) and r(b) are of degree lower than degree(p) and
|
||||
degree(a + b) <= max(degree(a), degree(b))
|
||||
Further valid are:
|
||||
(2): r(a) = r(r(a))
|
||||
(3): r(p * a) = 0
|
||||
|
||||
The residue of this expanded polynomial can be expressed by means of the
|
||||
residue r(a) which is known from the previous iteration step, and the
|
||||
residue r(b) which may be looked up in ccitt_table.
|
||||
r(a * X + b)
|
||||
= r(p * q(a) * X + r(a) * X + p * q(b) + r(b))
|
||||
|
||||
Applying rule (1):
|
||||
= r(p * q(a) * X) + r(r(a) * X) + r(p * q(b)) + r(r(b))
|
||||
|
||||
Rule (3) and rule (2):
|
||||
= r(r(a) * X) + r(b)
|
||||
|
||||
Be h(a) and l(a) chosen so that: r(a) = h(a) * X + l(a),
|
||||
and l(a) has zero coefficients above (x exp 7), and h(a) * X has zero
|
||||
coefficients below (x exp 8). (They correspond to the high and low byte
|
||||
of the 16 bit word crc(A).)
|
||||
So the previous statement can be written as:
|
||||
= r(h(a) * X * X) + r(l(a) * X) + r(b)
|
||||
|
||||
Since the degree of l(a) is lower than 8, the degree of l(a) * X is lower
|
||||
than 16. Thus it cannot be divisible by p which has degree 16.
|
||||
So: r(l(a) * X) = l(a) * X
|
||||
This yields
|
||||
= l(a) * X + r(h(a) * X * X + b)
|
||||
|
||||
h(a) * X * X is the polynomial representation of the high byte of 16 bit
|
||||
word crc(A).
|
||||
So in the world of bit patterns the iteration step is:
|
||||
|
||||
crc(byte string A expanded by byte B)
|
||||
= (low_byte(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ B)
|
||||
|
||||
And this is what function crc_ccitt() does, modulo swapping the exor
|
||||
operants and the final bit inversion which is prescribed by ECMA-130
|
||||
and MMC-3 Annex J.
|
||||
|
||||
The start value of the table driven byte shifting algorithm may be
|
||||
different from the start value of an equivalent bit shifting algorithm.
|
||||
This is because the final flushing by zero bits is already pre-computed
|
||||
in the table. So the start value of the table driven algorithm must be
|
||||
the CRC of the 0-polynomial under the start value of the bit shifting
|
||||
algorithm.
|
||||
This fact is not of much importance here, because the start value of
|
||||
the bit shifter is 0x0000 which leads to CRC 0x0000 and thus to start
|
||||
value 0x0000 with the table driven byte shifter.

= l(a) * X + r(h(a) * X * X * X * X + b)
|
||||
|
||||
h(a) * X * X * X * X is the polynomial representation of the high byte of
|
||||
32 bit word crc(A).
|
||||
So in the world of bit patterns we have:
|
||||
|
||||
crc(byte string A expanded by byte B)
|
||||
= (lowest_three_bytes(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ B)
|
||||
|
||||
|
||||
Regrettably this does not yet account for the byte-internal mirroring of
|
||||
bits during the conversion from bit pattern to polynomial, and during
|
||||
conversion from polynomial residue to bit pattern.
|
||||
|
||||
Be rfl8(D) the result of byte-internal mirroring of bit pattern D,
|
||||
and mirr8(d) its corresponding polynom.
|
||||
|
||||
Be now h(a) and l(a) chosen so that: r(mirr8(a)) = h(a) * X * X * X + l(a)
|
||||
This corresponds to highest byte and lower three bytes of crc(A).
|
||||
|
||||
r(mirr8(a) * X + mirr8(b))
|
||||
= r(h(a) * X * X * X * X) + r(l(a) * X) + r(mirr8(b))
|
||||
= l(a)) * X + r(h(a) * X * X * X * X + mirr8(b))
|
||||
|
||||
The corresponding bit pattern operation is
|
||||
|
||||
crc(mirrored byte string A expanded by mirrored byte B)
|
||||
= (lowest_three_bytes(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ rfl8(B))
|
||||
|
||||
This demands a final result mirroring to meet the ECMA-130 prescription.
|
||||
|
||||
rfl8() can be implemented as lookup table.
|
||||
|
||||
The start value of the bit shifting iteration is 0x00000000, which leads
|
||||
to the same start value for the table driven byte shifting.
|
||||
|
||||
The following function crc32_by_tab() yields the same results as functions
|
||||
crc_18001801b() and crc_32():

Above function yields sufficient performance, nevertheless the old function
|
||||
crc_32() (see below) is faster by avoiding the additional mirror table
|
||||
lookup.
|
||||
A test with 10 times 650 MB on 3000 MHz amd64:
|
||||
crc_18001801b : 187 s
|
||||
crc32_by_tab : 27 s
|
||||
crc_32 : 16 s
|
||||
|
||||
So how does crc_32() avoid the application of bit mirroring to B ?.
|
||||
|
||||
Inherited crc_32() performs
|
||||
crc = crc32_table[(crc ^ *data++) & 0xffL] ^ (crc >> 8);
|
||||
|
||||
Above function crc32_by_tab() would be
|
||||
crc = crc_tab[(crc >> 24) ^ mirr_tab[*data++]] ^ (crc << 8);
|
||||
|
||||
The shortcut does not change the polynomial representation of the algorithm
|
||||
or the mapping from and to bit patterns. It only mirrors the bit direction
|
||||
in the bytes and in the 32-bit words which are involved in the bit pattern
|
||||
computation. This affects input (which is desired), intermediate state
|
||||
(which is as good as unmirrored), and final output (which would be slightly
|
||||
undesirable if libburn could not use the mirrored result anyway).
|
||||
|
||||
Instead of the high byte (crc >> 24), the abbreviated algorithm uses
|
||||
the low byte of the mirrored intermediate checksum (crc & 0xffL).
|
||||
Instead of shifting the other three intermediate bytes to the left
|
||||
(crc << 8), the abbreviated algorithm shifts them to the right (crc >> 8).
|
||||
In both cases they overwrite the single byte that was used for computing
|
||||
the table index.
|
||||
|
||||
The byte indexed table of CRC values needs to hold mirrored 32 bit values.
|
||||
The byte index [(crc ^ *data++) & 0xffL] would need to be mirrored, which
|
||||
would eat up the gain of not mirroring the input bytes. But this mirroring
|
||||
can be pre-computed into the table by exchanging each value with the value
|
||||
of its mirrored index.
|
||||
|
||||
So this relation exists between the CRC table crc_tab[] of crc32_by_tab()
|
||||
and the table crc32_table[] of the abbreviated algorithm crc_32():
|
||||
|
||||
crc_tab[i] == rfl32(crc32_table[rfl8(i)])
|
||||
|
||||
for i={0..255}.
|
||||
|
||||
I compared the generated table in crc32_by_tab() by this test
|
||||
for (i = 0; i < 256; i++) {
|
||||
if (rfl32(crc_tab[rfl8(i)]) != crc32_table[i] ||
|
||||
crc_tab[i] != rfl32(crc32_table[rfl8(i)])) {
|
||||
printf("DEVIATION : i = %d\n", i);
|
||||
exit(1);
|
||||
}
|
||||
}
|
||||
No screaming abort happened.

This code module implements the production of RSPC parity bytes (P- and Q-
|
||||
parity) and the scrambling of raw CD-ROM sectors as specified in ECMA-130:
|
||||
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-130.pdf
|
||||
|
||||
The following statements about Galois Fields have been learned mostly from
|
||||
http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
|
||||
by James S. Plank after an e-mail exchange with Norbert Preining.
|
||||
|
||||
The output has been compared with the output of the old code of libburn
|
||||
which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
|
||||
Schilling to stem from code by Heiko Eissfeldt.
|
||||
|
||||
-------------------------------------------------------------------------
|
||||
Note: In this text, "^" denotes exponentiation and not the binary exor
|
||||
operation. Confusingly in the C code "^" is said exor.
|
||||
Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
|
||||
always performed inside the drive.
|
||||
-------------------------------------------------------------------------
|
||||
|
||||
|
||||
RSPC resp. P- and Q-Parity
|
||||
|
||||
ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
|
||||
Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
|
||||
polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
|
||||
Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
|
||||
as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
|
||||
and a MSB matrix of the same layout. Parity bytes are to be computed
|
||||
from these 8-bit values.
|
||||
2 P-bytes cover each column of 24 bytes. They get appended to the matrix
|
||||
as rows 24 and 25.
|
||||
2 Q-bytes cover each the 26 diagonals of the extended matrix.
|
||||
|
||||
Both parity byte pairs have to be computed so that extended rows or
|
||||
diagonals match this linear equation:
|
||||
H x V = (0,0)
|
||||
H is a 2-row matrix of size n matching the length of the V ectors
|
||||
[ 1 1 ... 1 1 ]
|
||||
[ x^(n-1) x^(n-2) x^1 1 ]
|
||||
Vp represents a P-row. It is a byte vector consisting of row bytes at
|
||||
position 0 to 23 and the two parity bytes which shall be determined
|
||||
at position 24 and 25. So Hp has 26 columns.
|
||||
Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
|
||||
bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
|
||||
So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
|
||||
|
||||
By applying some high school algebra one gets the parity bytes b0, b1 of
|
||||
vector V = (n_payload_bytes, b0 , b1) as
|
||||
|
||||
b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
|
||||
/ (H[n+1] - H[n])
|
||||
b1 = - SUM(n_payload_bytes) - b0
|
||||
|
||||
H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
|
||||
The result has to be computed by Galois field arithmetics. See below.
|
||||
|
||||
The P-parity bytes of each column get reunited as LSB and MSB of two words.
|
||||
word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
|
||||
The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
|
||||
to 1143, word0 to 1144 to 1169.
|
||||
>>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
|
||||
>>> But the new output matches the old output only if it is done that way.
|
||||
>>> See correctness reservation below.
|
||||
|
||||
Algebra on Galois fields is the same as on Rational Numbers.
|
||||
But arithmetics is defined by operations on polynomials rather than the
|
||||
usual integer arithmetics on binary numbers.
|
||||
Addition and subtraction are identical with the binary exor operator.
|
||||
Multiplication and division would demand polynomial division, e.g. by the
|
||||
euclidian algorithm. The computing path over logarithms and powers follows
|
||||
algebra and allows to reduce the arithmetic task to table lookups, additions
|
||||
modulo 255, and exor operations. Note that the logarithms are natural
|
||||
numbers, not polynomials. They get added or subtracted by the usual addition
|
||||
(not by exor) and their polynomial power depends on their value modulo 255.
|
||||
|
||||
Needed are a logarithm table and a power table (or inverse logarithm table)
|
||||
for Galois Field GF(2^8) which will serve to perform the peculiar
|
||||
multiplication and division operation of Galois fields.
|
||||
|
||||
The power table is simply an enumeration of x^n accorting to
|
||||
GF-multiplication. It also serves as second line of matrix H for the parity
|
||||
equations:
|
||||
Hp[i] = gfpow[25-i] , i out of {0,..,25}
|
||||
Hq[i] = gfpow[44-i] , i out of {0,..,44}
|
||||
|
||||
The logarithm table is the inverse permutation of the power table.
|
||||
|
||||
Some simplifications apply to the implementation:
|
||||
In the world of Galois fields there is no difference between - and +.
|
||||
The term (H[n+1] - H[n]) is constant: 3.
|
||||
|
||||
-------------------------------------------------------------------------
|
||||
|
||||
|
||||
Scrambling
|
||||
|
||||
ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
|
||||
with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
|
||||
a 15-bit register.
|
||||
It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
|
||||
|
||||
Comparing this with explanations in
|
||||
http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
|
||||
one can recognize the diagram as a Fibonacci Implementation. But there seems
|
||||
really to be one bit box too many.
|
||||
|
||||
The difference of both lengths is expressed in function next_bit() by
|
||||
the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
|
||||
Comparing the output of both alternatives with the old scrambler output
|
||||
lets 15 bit win for now.
|
||||
|
||||
So the prescription is to start with 15 bit value 1, to use the lowest bit
|
||||
as output, to shift the bits down by one, to exor the output bit with the
|
||||
next lowest bit, and to put that exor result into bit 14 of the register.
|
||||
|
||||
-------------------------------------------------------------------------
|
||||
|
||||
|
||||
Correctness Reservation
|
||||
|
||||
In both cases, parity and scrambling, the goal for now is to replicate the
|
||||
output of the dismissed old lec.c by output which is based on published
|
||||
specs and own implementation code. Whether they comply to ECMA-130 is a
|
||||
different question which can only be answered by real test cases for
|
||||
raw CD recording.
|
||||
|
||||
Of course this implementation will be corrected so that it really complies
|
||||
to ECMA-130 as soon as evidence emerges that it does not yet.

libdax_msgs is designed to serve in libraries which want to offer their
|
||||
applications a way to control the output of library messages. It shall be
|
||||
incorporated by an owner, i.e. a software entity which encloses the code
|
||||
of the .c file.
|
||||
|
||||
Owner of libdax_msgs is libburn. A fully compatible variant named libiso_msgs
|
||||
is owned by libisofs and can get generated by a script of the libburn
|
||||
project: libburn/libdax_msgs_to_xyz_msgs.sh .
|
||||
|
||||
Reason: One cannot link two owners of the same variant together because
|
||||
both would offer the same functions to the linker. For that situation one
|
||||
has to create a compatible variant as it is done for libisofs.
|
||||
|
||||
Compatible variants may get plugged together by call combinations like
|
||||
burn_set_messenger(iso_get_messenger());
|
||||
A new variant would demand a _set_messenger() function if it has to work
|
||||
with libisofs. If only libburn is planned as link partner then a simple
|
||||
_get_messenger() does suffice.
|
||||
Take care to shutdown libburn before its provider of the *_msgs object
|
||||
gets shut down.

This is an alternative representation of libisofs.so.6 error codes in xorriso.

|

This is the main operating system dependent SCSI part of libburn. It implements
|
||||
the transport level aspects of SCSI control and command i/o.
|
||||
|
||||
Present implementation: Solaris uscsi, e.g. for SunOS 5.11
|
||||
|
||||
|
||||
PORTING:
|
||||
|
||||
Porting libburn typically will consist of adding a new operating system case
|
||||
to the following switcher files:
|
||||
os.h Operating system specific libburn definitions and declarations.
|
||||
sg.c Operating system dependent transport level modules.
|
||||
and of deriving the following system specific files from existing examples:
|
||||
os-*.h Included by os.h. You will need some general system knowledge
|
||||
about signals and knowledge about the storage object needs of your
|
||||
transport level module sg-*.c.
|
||||
|
||||
sg-*.c This source module. You will need special system knowledge about
|
||||
how to detect all potentially available drives, how to open them,
|
||||
eventually how to exclusively reserve them, how to perform
|
||||
SCSI transactions, how to inquire the (pseudo-)SCSI driver.
|
||||
You will not need to care about CD burning, MMC or other high-level
|
||||
SCSI aspects.
|
||||
|
||||
Said sg-*.c operations are defined by a public function interface, which has
|
||||
to be implemented in a way that provides libburn with the desired services:
|
||||
|
||||
sg_id_string() returns an id string of the SCSI transport adapter.
|
||||
It may be called before initialization but then may
|
||||
return only a preliminary id.
|
||||
|
||||
sg_initialize() performs global initialization of the SCSI transport
|
||||
adapter and eventually needed operating system
|
||||
facilities. Checks for compatibility of supporting
|
||||
software components.
|
||||
|
||||
sg_shutdown() performs global finalizations and releases golbally
|
||||
aquired resources.
|
||||
|
||||
sg_give_next_adr() iterates over the set of potentially useful drive
|
||||
address strings.
|
||||
|
||||
scsi_enumerate_drives() brings all available, not-whitelist-banned, and
|
||||
accessible drives into libburn's list of drives.
|
||||
|
||||
sg_dispose_drive() finalizes adapter specifics of struct burn_drive
|
||||
on destruction. Releases resources which were aquired
|
||||
underneath scsi_enumerate_drives().
|
||||
|
||||
sg_drive_is_open() tells wether libburn has the given drive in use.
|
||||
|
||||
sg_grab() opens the drive for SCSI commands and ensures
|
||||
undisturbed access.
|
||||
|
||||
sg_release() closes a drive opened by sg_grab()
|
||||
|
||||
sg_issue_command() sends a SCSI command to the drive, receives reply,
|
||||
and evaluates wether the command succeeded or shall
|
||||
be retried or finally failed.
|
||||
|
||||
sg_obtain_scsi_adr() tries to obtain SCSI address parameters.
|
||||
|
||||
|
||||
burn_os_is_2k_seekrw() tells whether the given path leads to a file object
|
||||
that can be used in 2 kB granularity by lseek(2),
|
||||
read(2), and possibly write(2) if not read-only..
|
||||
E.g. a USB stick or a hard disk.
|
||||
|
||||
burn_os_stdio_capacity() estimates the emulated media space of stdio-drives.
|
||||
|
||||
burn_os_open_track_src() opens a disk file in a way that allows best
|
||||
throughput with file reading and/or SCSI write command
|
||||
transmission.
|
||||
|
||||
burn_os_alloc_buffer() allocates a memory area that is suitable for file
|
||||
descriptors issued by burn_os_open_track_src().
|
||||
The buffer size may be rounded up for alignment
|
||||
reasons.
|
||||
|
||||
burn_os_free_buffer() delete a buffer obtained by burn_os_alloc_buffer().
|
||||
|
||||
Porting hints are marked by the text "PORTING:".

Description of the helper program stic*/bin/cgen
|
||||
|
||||
cgen is copyright 2001 to 2007, Thomas Schmitt <stic-source@gmx.net>
|
||||
and provided under BSD license.
|
||||
|
||||
Compilation:
|
||||
cc -g -o cgen cgen.c ctyp.c smem.c
|
||||
|
||||
|
||||
cgen produces a class stub in C programming language. The data structure of
|
||||
the class is described by some lines which get read from stdin. The stub will
|
||||
consist of four files which emerge in the current working directory:
|
||||
<classname>.h public header file of the class
|
||||
<classname>.c automatically generated C code of the class
|
||||
plus a copy of <classname>.c.methods
|
||||
<classname>_private.h private header file of the class
|
||||
<classname>.c.methods safe storage for manually created functions.
|
||||
From here they get copied into the generated stub.
|
||||
If such a file is missing, a dummy gets created.
|
||||
It will define a struct <ClassnamE> for representing the class data aspects,
|
||||
construtor <Classname>_new(), destructor <Classname>_destroy(),
|
||||
getter <Classname>_<element>_get() for each structure element.
|
||||
Some more functions get added for particular class and element roles.
|
||||
|
||||
cgen normally refuses to overwrite existing files because it supposes that
|
||||
those contain code added by the human programmer.
|
||||
Human programmer enhancements may be explanatory comments, class specific
|
||||
methods, initial element values and other special precautions within the
|
||||
generated functions.
|
||||
As long as the modelling phase is going on, one may store such human code
|
||||
in <classname>.c.methods and may use command line option -overwrite for
|
||||
modelling development cycles.
|
||||
|
||||
At some point of model matureness one may decide to give up cgen and the
|
||||
.c.method files and to go on only with _private.h , .h and .c files.
|
||||
|
||||
|
||||
Command line options
|
||||
|
||||
-no_stic prevents usage of stic_dir/s_tools/*.[ch]
|
||||
|
||||
-ansi generates ANSI C function heads and makes file <classname>.h hold
|
||||
only public definitions: an opaque declaration of the class struct
|
||||
and a list of function prototypes. The definiton of the class
|
||||
struct is then in <classname>_private.h .
|
||||
-global_include filename
|
||||
sets the name of a file which will contain globally necessary
|
||||
declarations. Currently it lists the existence of all class
|
||||
structs.
|
||||
-lowercase generate struct <classname> rather than struct <ClassnamE> and
|
||||
function names <classname>_func() rather than <Classname>_func() .
|
||||
-overwrite allows to overwrite files <classname>_private.h, <classname>.h
|
||||
and <classname>.c, but not <classname>.c.methods.
|
||||
|
||||
|
||||
Input line format:
|
||||
|
||||
There are two states of input: class level and element level.
|
||||
Exampes are shown below with class roles and element roles.
|
||||
|
||||
Input starts at class level. A class level line may be one of
|
||||
|
||||
- Comment. A line which begins with '#' is ignored on class level.
|
||||
|
||||
- Empty. A line with no characters is a comment with empty text (i.e. ignored).
|
||||
|
||||
- Class. Options which begin with '-' and finally a word in lowercase letters
|
||||
which defines the <classname>. The classname leads to a struct ClassnamE
|
||||
and some class methods implemented as C functions <Classnname>_<func>().
|
||||
|
||||
- End of input. Line "@@@" or EOF at stdin end the program run.
|
||||
|
||||
After a class line, input switches to element level where a line may be:
|
||||
|
||||
- Comment. A line which after some white space begins with '#' is considered
|
||||
a comment. The preceeding white space is ignored and the text after '#' is
|
||||
eventuellay trimmed by a single blank at both ends. This text will be part
|
||||
of the class struct definition within file <classname_private>.h as a single
|
||||
C comment line /* ... */. The sequence of elements and comments is preserved.
|
||||
An empty comment text leads to an empty line in <classname_private>.h.
|
||||
|
||||
- Empty. A line with no characters is a comment with empty text.
|
||||
|
||||
- Element. Options which begin with '-', eventual C keywords "unsigned" or
|
||||
"volatile", type or "struct <NamE>", element name. This leads to a struct
|
||||
element which is taken into respect in some class methods. Depending on the
|
||||
options in this line, some element methods <Classnname>_<func>_<element>()
|
||||
may get generated.
|
||||
|
||||
- End of class. A single '@' marks the end of the element list and brings
|
||||
input back to class level. I.e. next is expected another class name or
|
||||
"@@@" or EOF at stdin.
|
||||
|
||||
Input semantics:
|
||||
|
||||
A class can have one of two roles:
|
||||
|
||||
- Standalone class.
|
||||
Input example:
|
||||
my_class
|
||||
|
||||
- Listable class, which has pointers to peer instances: .prev and .next
|
||||
Such classes get a list destructor <Classname>_destroy_all() which destroys
|
||||
all members of a list (which is given by any of the list members).
|
||||
Such a class should have a pointer *boss as first element in which case
|
||||
the constructor will look like
|
||||
<Classname>_new(struct <ClassnamE> **o,struct <Some_clasS> *boss,int flag);
|
||||
There is a function <Classname>_link() which inserts an instance into a list
|
||||
and a function <Classname>_count() which tells the number of list members.
|
||||
For pseudo random access there is function <Classname>_by_idx().
|
||||
Input example:
|
||||
-l my_class
|
||||
|
||||
|
||||
A modifier is defined for classes:
|
||||
|
||||
- Bossless. Disables a special boss-subordinate relationship which is created
|
||||
if the first element of a class is a struct pointer with the name "boss".
|
||||
Like
|
||||
-l <classname>
|
||||
-v struct Some_clasS *boss
|
||||
Normally such a parameter *boss becomes part of the constructor method
|
||||
<Classname>_new(struct <ClassnamE> **o, struct Some_clasS *boss, int flag);
|
||||
This relationship is typical for a listable class and a single class which
|
||||
is designed to host instances of that listable class. Therefore one gets a
|
||||
warning if a listable class does not begin with a struct pointer *boss.
|
||||
But if -b is given, then CgeN ill not include a parameter *boss into the
|
||||
constructor. It will rather look normal:
|
||||
<Classname>_new(struct <ClassnamE> **o, int flag);
|
||||
It will not warn if the first element of a listable class is not struct
|
||||
pointer *boss.
|
||||
|
||||
|
||||
Elements have one of the following roles:
|
||||
|
||||
- Value. It provides only storage for a C data type (which may be a C pointer
|
||||
despite the role name "value"), a getter method <Classname>_<element>_get(),
|
||||
and a setter method <Classname>_<element>_set().
|
||||
Input examples:
|
||||
-v int i
|
||||
-v int a[100]
|
||||
-v char *cpt
|
||||
-v struct xyz x
|
||||
-v struct xyz *xpt
|
||||
|
||||
- Managed. This has to be a pointer to a struct <XyZ> or to char. It will not
|
||||
get attached to an object by the stub's code but its destructor
|
||||
<Xyz>_destroy() will be called by <Classname>_destruct(). In case of (char *)
|
||||
it is supposed that a non-NULL value has been allocated by malloc().
|
||||
Managed (char *) types get a setter function <Classname>_<element>_set()
|
||||
which allocates memory and copies the textstring from its parameter.
|
||||
Input examples:
|
||||
-m struct XyZ *xyzpt
|
||||
-m char *textstring
|
||||
|
||||
- Chainlink. A pair of prev-next-style pointers to the own class struct.
|
||||
Function <Classname>_destruct() will unlink the affected instance and
|
||||
put together its link partners.
|
||||
Input example (there must always be two consequtive -c lines):
|
||||
-c struct My_clasS *up
|
||||
-c struct My_clasS *down
|
||||
|
||||
- List. A pair of pointers to the struct <XyZ> of a listable class. The first
|
||||
one <ls> holds the start of the list, the second one <eol> holds the end.
|
||||
The getter function has an additional argument idx:
|
||||
<Classname>_get_<ls>(struct <ClassnamE> *o, int idx, struct <XyZ> **pt,
|
||||
int flag)
|
||||
idx == 0 is the start of the list, idx=1 the next element, ...
|
||||
idx == -1 retrieves the last element of the list.
|
||||
For insertion of list items there is provided method <Classname>_new_<ls>().
|
||||
The inserted item is reachable via the getter function with idx == -1
|
||||
<Classname>_destroy() instance calls <Xyz>_destroy_all(). Note that the end
|
||||
pointer is always generated as private element (-p).
|
||||
Input example (there must always be a -l and a -v line):
|
||||
-l struct XyZ *list_start
|
||||
-v struct XyZ *list_end
|
||||
|
||||
The availability of getter method <Classname>_get_<element>(), and setter
|
||||
method <Classname>_set_<element>_set() can be controled by two modifiers:
|
||||
|
||||
- Readonly. Only a getter method.
|
||||
Input example
|
||||
-r -v int broadcasted_status
|
||||
|
||||
- Private. Neither getter nor setter method.
|
||||
Input example
|
||||
-p -v int private_value
|
||||
|
||||
- Bossless listable. This marks elements which are listable objects but do not
|
||||
expect a boss pointer in their constructor. See above: Listable class and
|
||||
the bossless modifier for classes.
|
||||
Input example
|
||||
-b -l struct XyZ *list
|
||||
-v struct XyZ *last_in_list
|
||||
|
||||
- Initialization free. The class constructor will not initialize this element.
|
||||
This modifier has to be used if neither NULL nor 0 are suitable
|
||||
initialization values.
|
||||
|
||||
Example run:
|
||||
|
||||
rm class_x.c class_x.h class_y.c class_y.h
|
||||
bin/cgen <<+
|
||||
-l class_x
|
||||
-r -v struct Boss_clasS *boss
|
||||
-v int x
|
||||
-r -v struct stat stbuf
|
||||
-m struct Class_Y *y
|
||||
-m char *text
|
||||
-c struct Class_X *master
|
||||
-c struct Class_X *slave
|
||||
-b -l struct Class_X *provider
|
||||
