|
||||
Basic Installation
|
||||
==================
|
||||
|
||||
Briefly, the shell commands `./configure; make; make install' should
|
||||
configure, build, and install this package. The following
|
||||
more-detailed instructions are generic; see the `README' file for
|
||||
instructions specific to this package.
|
||||
|
||||
The `configure' shell script attempts to guess correct values for
|
||||
various system-dependent variables used during compilation. It uses
|
||||
those values to create a `Makefile' in each directory of the package.
|
||||
It may also create one or more `.h' files containing system-dependent
|
||||
definitions. Finally, it creates a shell script `config.status' that
|
||||
you can run in the future to recreate the current configuration, and a
|
||||
file `config.log' containing compiler output (useful mainly for
|
||||
debugging `configure').
|
||||
|
||||
It can also use an optional file (typically called `config.cache'
|
||||
and enabled with `--cache-file=config.cache' or simply `-C') that saves
|
||||
the results of its tests to speed up reconfiguring. Caching is
|
||||
disabled by default to prevent problems with accidental use of stale
|
||||
cache files.
|
||||
|
||||
If you need to do unusual things to compile the package, please try
|
||||
to figure out how `configure' could check whether to do them, and mail
|
||||
diffs or instructions to the address given in the `README' so they can
|
||||
be considered for the next release. If you are using the cache, and at
|
||||
some point `config.cache' contains results you don't want to keep, you
|
||||
may remove or edit it.
|
||||
|
||||
The file `configure.ac' (or `configure.in') is used to create
|
||||
`configure' by a program called `autoconf'. You need `configure.ac' if
|
||||
you want to change it or regenerate `configure' using a newer version
|
||||
of `autoconf'.
|
||||
|
||||
The simplest way to compile this package is:
|
||||
|
||||
1. `cd' to the directory containing the package's source code and type
|
||||
`./configure' to configure the package for your system.
|
||||
|
||||
Running `configure' might take a while. While running, it prints
|
||||
some messages telling which features it is checking for.
|
||||
|
||||
2. Type `make' to compile the package.
|
||||
|
||||
3. Optionally, type `make check' to run any self-tests that come with
|
||||
the package.
|
||||
|
||||
4. Type `make install' to install the programs and any data files and
|
||||
documentation.
|
||||
|
||||
5. You can remove the program binaries and object files from the
|
||||
source code directory by typing `make clean'. To also remove the
|
||||
files that `configure' created (so you can compile the package for
|
||||
a different kind of computer), type `make distclean'. There is
|
||||
also a `make maintainer-clean' target, but that is intended mainly
|
||||
for the package's developers. If you use it, you may have to get
|
||||
all sorts of other programs in order to regenerate files that came
|
||||
with the distribution.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems require unusual options for compilation or linking that the
|
||||
`configure' script does not know about. Run `./configure --help' for
|
||||
details on some of the pertinent environment variables.
|
||||
|
||||
You can give `configure' initial values for configuration parameters
|
||||
by setting variables in the command line or in the environment. Here
|
||||
is an example:
|
||||
|
||||
./configure CC=c99 CFLAGS=-g LIBS=-lposix
|
||||
|
||||
*Note Defining Variables::, for more details.
|
||||
|
||||
Compiling For Multiple Architectures
|
||||
====================================
|
||||
|
||||
You can compile the package for more than one kind of computer at the
|
||||
same time, by placing the object files for each architecture in their
|
||||
own directory. To do this, you can use GNU `make'. `cd' to the
|
||||
directory where you want the object files and executables to go and run
|
||||
the `configure' script. `configure' automatically checks for the
|
||||
source code in the directory that `configure' is in and in `..'.
|
||||
|
||||
With a non-GNU `make', it is safer to compile the package for one
|
||||
architecture at a time in the source code directory. After you have
|
||||
installed the package for one architecture, use `make distclean' before
|
||||
reconfiguring for another architecture.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, `make install' installs the package's commands under
|
||||
`/usr/local/bin', include files under `/usr/local/include', etc. You
|
||||
can specify an installation prefix other than `/usr/local' by giving
|
||||
`configure' the option `--prefix=PREFIX'.
|
||||
|
||||
You can specify separate installation prefixes for
|
||||
architecture-specific files and architecture-independent files. If you
|
||||
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
|
||||
PREFIX as the prefix for installing programs and libraries.
|
||||
Documentation and other data files still use the regular prefix.
|
||||
|
||||
In addition, if you use an unusual directory layout you can give
|
||||
options like `--bindir=DIR' to specify different values for particular
|
||||
kinds of files. Run `configure --help' for a list of the directories
|
||||
you can set and what kinds of files go in them.
|
||||
|
||||
If the package supports it, you can cause programs to be installed
|
||||
with an extra prefix or suffix on their names by giving `configure' the
|
||||
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
Some packages pay attention to `--enable-FEATURE' options to
|
||||
`configure', where FEATURE indicates an optional part of the package.
|
||||
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
|
||||
is something like `gnu-as' or `x' (for the X Window System). The
|
||||
`README' should mention any `--enable-' and `--with-' options that the
|
||||
package recognizes.
|
||||
|
||||
For packages that use the X Window System, `configure' can usually
|
||||
find the X include and library files automatically, but if it doesn't,
|
||||
you can use the `configure' options `--x-includes=DIR' and
|
||||
`--x-libraries=DIR' to specify their locations.
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features `configure' cannot figure out automatically,
|
||||
but needs to determine by the type of machine the package will run on.
|
||||
Usually, assuming the package is built to be run on the _same_
|
||||
architectures, `configure' can figure that out, but if it prints a
|
||||
message saying it cannot guess the machine type, give it the
|
||||
`--build=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as `sun4', or a canonical name which has the form:
|
||||
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
where SYSTEM can have one of these forms:
|
||||
|
||||
OS KERNEL-OS
|
||||
|
||||
See the file `config.sub' for the possible values of each field. If
|
||||
`config.sub' isn't included in this package, then this package doesn't
|
||||
need to know the machine type.
|
||||
|
||||
If you are _building_ compiler tools for cross-compiling, you should
|
||||
use the option `--target=TYPE' to select the type of system they will
|
||||
produce code for.
|
||||
|
||||
If you want to _use_ a cross compiler, that generates code for a
|
||||
platform different from the build platform, you should specify the
|
||||
"host" platform (i.e., that on which the generated programs will
|
||||
eventually be run) with `--host=TYPE'.
|
||||
|
||||
Sharing Defaults
|
||||
================
|
||||
|
||||
If you want to set default values for `configure' scripts to share, you
|
||||
can create a site shell script called `config.site' that gives default
|
||||
values for variables like `CC', `cache_file', and `prefix'.
|
||||
`configure' looks for `PREFIX/share/config.site' if it exists, then
|
||||
`PREFIX/etc/config.site' if it exists. Or, you can set the
|
||||
`CONFIG_SITE' environment variable to the location of the site script.
|
||||
A warning: not all `configure' scripts look for a site script.
|
||||
|
||||
Defining Variables
|
||||
==================
|
||||
|
||||
Variables not defined in a site shell script can be set in the
|
||||
environment passed to `configure'. However, some packages may run
|
||||
configure again during the build, and the customized values of these
|
||||
variables may be lost. In order to avoid this problem, you should set
|
||||
them in the `configure' command line, using `VAR=value'. For example:
|
||||
|
||||
./configure CC=/usr/local2/bin/gcc
|
||||
|
||||
causes the specified `gcc' to be used as the C compiler (unless it is
|
||||
overridden in the site shell script).
|
||||
|
||||
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
|
||||
an Autoconf bug. Until the bug is fixed you can use this workaround:
|
||||
|
||||
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
|
||||
|
||||
`configure' Invocation
|
||||
======================
|
||||
|
||||
`configure' recognizes the following options to control how it operates.
|
||||
|
||||
`--help'
|
||||
`-h'
|
||||
Print a summary of the options to `configure', and exit.
|
||||
|
||||
`--version'
|
||||
`-V'
|
||||
Print the version of Autoconf used to generate the `configure'
|
||||
script, and exit.
|
||||
|
||||
`--cache-file=FILE'
|
||||
Enable the cache: use and save the results of the tests in FILE,
|
||||
traditionally `config.cache'. FILE defaults to `/dev/null' to
|
||||
disable caching.
|
||||
|
||||
`--config-cache'
|
||||
`-C'
|
||||
Alias for `--cache-file=config.cache'.
|
||||
|
||||
`--quiet'
|
||||
`--silent'
|
||||
`-q'
|
||||
Do not print messages saying which checks are being made. To
|
||||
suppress all normal output, redirect it to `/dev/null' (any error
|
||||
messages will still be shown).
|
||||
|
||||
`--srcdir=DIR'
|
||||
Look for the package's source code in directory DIR. Usually
|
||||
`configure' can determine that directory automatically.
|
||||
|
||||
`configure' also accepts some other, not widely useful, options. Run
|
||||
`configure --help' for more details.

|
||||
Build and Installation
|
||||
|
||||
From tarball
|
||||
Our build system is based on autotools.
|
||||
User experience tells us that you will need at least autotools version 1.7.
|
||||
|
||||
Obtain libburn-1.4.2.pl01.tar.gz, take it to a directory of your choice and do:
|
||||
|
||||
tar xzf libburn-1.4.2.pl01.tar.gz
|
||||
cd libburn-1.4.2
|
||||
./configure --prefix=/usr
|
||||
To build libburn.pykix.org and its subprojects it should be sufficient to go
|
||||
into its toplevel directory and execute
|
||||
./bootstrap (needed if you downloaded from SVN and not a release tarball)
|
||||
./configure
|
||||
make
|
||||
|
||||
To make libburn accessible for running and application development,
|
||||
and to install the cdrecord compatibility binary cdrskin, do
|
||||
(as Superuser):
|
||||
|
||||
To make the libraries accessible for running resp. developing applications
|
||||
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
|
||||
./bootstrap
|
||||
./configure --prefix=/usr
|
||||
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 or 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
|
||||
make install
|
||||
|
||||
|
||||
Linux only:
|
||||
|
||||
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"

|
||||
Overview of libburnia-project.org
|
||||
|
||||
libburnia-project.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.
|
||||
libburn.pykix.org is an open-source library for reading, mastering and writing
|
||||
optical discs. For now this means only CD-R and CD-RW.
|
||||
|
||||
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),
|
||||
on OpenSolaris (tested with kernel 5.11),
|
||||
on NetBSD (tested with 6.1.3).
|
||||
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
|
||||
or 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 and we will have a hard time to widen
|
||||
this for now, because of our history. The project could need advise from or
|
||||
membership of skilled kernel people and people who know how to talk CD/DVD
|
||||
drives into doing things.
|
||||
|
||||
We have a well tested code base for burning data and audio CDs, DVDs and BDs.
|
||||
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 do have a workable code base for burning data CDs, though. The burn API is
|
||||
quite comprehensively documented and can be used to build a presentable
|
||||
application.
|
||||
We do have a functional binary which emulates parts 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.
|
||||
|
||||
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.
|
||||
/dev/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation.
|
||||
|
||||
- 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 can 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.
|
||||
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
|
||||
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 capabilities, where only -sao is compatible
|
||||
with cdrecord.
|
||||
the services traditionally provided by 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.
|
||||
|
||||
- xorriso is an application of all three libraries which creates, loads,
|
||||
manipulates and writes ISO 9660 filesystem images with
|
||||
Rock Ridge extensions. Manipulation is not only adding or
|
||||
overwriting of files but also deleting, renaming, attribute
|
||||
changing, incremental backups, activating boot images, and
|
||||
extracting of files from ISO images to disk. There is also a
|
||||
sparse emulation of cdrecord and a more laborate one of mkisofs.
|
||||
All features of xorriso are also available via a C language API
|
||||
of libisoburn.
|
||||
A static compilation of xorriso and the libraries is dedicated
|
||||
to the GNU Operating System. See xorriso/README_gnu_xorriso .
|
||||
|
||||
- "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 strive to be a responsive upstream.
|
||||
|
||||
Our libraries are committed to maintain older feature sets in newer versions.
|
||||
This applies to source code headers (API) as well as to linkable objects (ABI).
|
||||
The only exception from this rule is about non-release versions x.y.*[13579]
|
||||
which are allowed to introduce new features, change those new features in
|
||||
any way and even may revoke such new features before the next release of
|
||||
x.y.*[02468]. As soon as it is released, a feature is promised to persist.
|
||||
|
||||
SONAMES:
|
||||
libburn.so.4 (since 0.3.4, March 2007),
|
||||
libisofs.so.6 (since 0.6.2, February 2008),
|
||||
libisoburn.so.1 (since 0.1.0, February 2008).
|
||||
|
||||
Applications must use 64 bit off_t. E.g. by defining
|
||||
#define _LARGEFILE_SOURCE
|
||||
#define _FILE_OFFSET_BITS 64
|
||||
or take special precautions to interface with the libraries by 64 bit integers
|
||||
where the .h files prescribe off_t. To reduce libburn's off_t size to 32 bit
|
||||
will keep it from processing tracks of more than 2 GB size.
|
||||
We plan to be a responsive upstream. Bear with us. We are still practicing.

- 20th September 2006 release of libburn-0.2.2 .
|
||||
|

- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
|
||||
This version of cdrskin is much more cdrecord compatible in repect
|
||||
to drive addressing and audio features.
|
||||
|
||||
- 30th October 2006 release of cdrskin-0.2.4 .
|

|
||||
- 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
|
||||
|
||||
- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
|
||||
become suitable for unaware frontends as long as they perform only the core
|
||||
of cdrecord use cases (including open-ended input streams, audio, and
|
||||
multi-session).
|
||||
|
||||
- 28th November 2006 the umbrella project which encloses both, libisofs and
|
||||
libburn, is now called libburnia. For the origin of this name, see
|
||||
http://en.wikipedia.org/wiki/Liburnians .
|
||||
|
||||
- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
|
||||
is widened to a first class of DVD media: overwriteable single layer types
|
||||
DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
|
||||
by dvd+rw-tools' "poor man" writing facility for this class of media.
|
||||
Taking a bow towards Andy Polyakov.
|
||||
|
||||
- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
|
||||
multi-session and with DAO.
|
||||
|
||||
- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
|
||||
DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
|
||||
yet.
|
||||
|
||||
- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
|
||||
people that one should not use /dev/sg on kernel 2.6.
|
||||
|
||||
- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
|
||||
We look back on improved stability, a substantially extended list of media
|
||||
and write modes, and better protection against typical user mishaps.
|
||||
|
||||
- 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.
|
||||
It is the first release of new libisofs.so.6 which will guarantee future
|
||||
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 enable 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
|
||||
pieces. A primitive single session emulation of cdrecord and mkisofs is
|
||||
provided.
|
||||
|
||||
- 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE,
|
||||
full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank
|
||||
type with automatic media state recognition.
|
||||
|
||||
- 17th May 2008 an old bug with DVD-RAM and now with BD-RE is fixed by
|
||||
libburn-0.4.8. So libisoburn can now perform emulation of multisession
|
||||
on those media.
|
||||
|
||||
- 19th May 2008 libisoburn-0.1.6 brings better table-of-content emulation
|

/dev/scd*.
|
||||
|
||||
- 19th Jul 2008 libisoburn/xorriso-0.2.2 can do multi-session in mkisofs
|
||||
and cdrecord style. xorriso now can serve underneath growisofs.
|
||||
|
||||
- 20th Aug 2008 libburn-0.5.2 revokes the necessity that a drive must be
|
||||
enumerable in order to be adressable. Enumeration is enhanced by examining
|
||||
/proc/sys/dev/cdrom/info.
|
||||
|
||||
- 24th Aug 2008 libisoburn/xorriso-0.2.4 introduces a media readability check
|
||||
with data retrieval option.
|
||||
|
||||
- 18th Sep 2008 libisofs-0.6.8 supports ISO 9660 Level 3 which can represent
|

very large data files in the image.
|
||||
|
||||
- 20th Sep 2008 libisoburn/xorriso-0.2.6 takes into respect the new Level 3
|

- 12th Nov 2008 libburn-0.5.6 fixes usage of freed memory by the fifo thread
|
||||
of an aborted burn run.
|
||||
|
||||
- 26th Nov 2008 libisofs-0.6.12 can produce a ISOLINUX isohybrid MBR on the fly
|
||||
and can produce ISO images which resemble old mkisofs images.
|
||||
|
||||
- 2nd Dec 2008 libisoburn-0.3.0. xorriso now is ready for exotic character
|
||||
sets, for legacy FreeBSD systems which expect an outdated Rock Ridge
|
||||
signature, and for producing ISO images with MBR which boot from hard disk
|
||||
or USB stick. Three minor bugs were fixed.
|
||||
|
||||
- 7th Dec 2008 libburn-0.5.8 prevents a SIGSEGV with wierd CD table-of-content
|
||||
and improves BD-RE formatting.

|
||||
|
||||
- 2nd Jan 2009 libburn-0.6.0 learned to format BD-R and write to either
|
||||
formatted or unformatted BD-R.
|
||||
|
||||
- 6th Jan 2009 libisoburn-0.3.2. xorriso can produce and execute commands for
|
||||
mounting older sessions from all kinds of media. Pseudo-drives outside the
|
||||
/dev/ tree can be addressed without prefix "stdio:".
|
||||
|
||||
- 20th Feb 2009 libburn-0.6.2 source release now compiles out of the box
|
||||
on FreeBSD.
|
||||
|
||||
- 28 Feb 2009 libisofs-0.6.14 can record ACLs and Extended Attributes xattr
|
||||
in its ISO images.

||||
|
||||
- 01 Mar 2009 libisoburn-0.3.4. xorriso makes use of the ACL and xattr
|
||||
capabilities provided by libisofs for xorriso backup features.
|
||||
|
||||
- 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 was precondition
|
||||
to lift the ban to build libburn on operating systems other than Linux
|
||||
and FreeBSD.
|
||||
|
||||
- 16 Mar 2009 libisoburn-0.3.6: xorriso uses RRIP version 1.10 as default
|
||||
in order to be mountable where mkisofs images are mountable.
|
||||
|
||||
- 17 Apr 2009 libisofs-0.6.18 introduces content filtering of data files.
|
||||
Built-in filters implement compression to formats gzip and zisofs. External
|
||||
filter processes can perform arbitrary data conversions like encryption.
|
||||
|
||||
- 19 Apr 2009 libisoburn-0.3.8 makes use of the new libisofs capability to
|
||||
perform content filtering of data files.
|
||||
|
||||
- 08 May 2009 libburn-0.6.6 fixes a bug with aborting on broken output pipe
|
||||
and a bug with device scan on FreeBSD.
|
||||
|
||||
- 31 May 2009 libisofs-0.6.20 can record hard link relations in ISO images
|
||||
and offers support with restoring them to disk. Current Linux kernels will
|
||||
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
|
||||
relations of files. Performance of data reading has been improved. Option
|
||||
-find now supports logical operators with its tests.
|
||||
|
||||
- 14 Jul 2009 libburn-0.6.8 fixes bugs and shortcommings with old MMC-1 drives
|
||||
and with large SCSI bus numbers as handed out by Linux for USB drives.
|
||||
|
||||
- 20 Jul 2009 libisoburn-0.4.0.pl01 fixes a regression in xorriso which caused
|
||||
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 can be used to verify superblock
|
||||
and directory tree before importing them.
|
||||
|
||||
- 27 Aug 2009 libburn-0.7.0 learned 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.
|
||||
|
||||
- 08 Oct 2009 libisofs-0.6.24 fixes a bug which could cause the loss of blanks
|
||||
in file names when a new session got added to an ISO image. With names
|
||||
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.
|
||||

|
||||
libcdio >= 0.83 as SCSI transport facility.
|
||||
|
||||
- 10 Feb 2010 libisofs-0.6.28 fixes a regression about bootable images which
|
||||
was introduced by version 0.6.22 in August 2009.
|
||||
|
||||
- 23 Feb 2010 libisoburn-0.5.0 marks the transition of the xorriso standalone
|
||||
version to an official GNU project. The name changed to "GNU xorriso" and its
|
||||
license is now GPLv3+.
|
||||
The licenses of libburnia libraries and applications are not affected by
|
||||
this change.
|
||||
|
||||

|
||||
multiple boot images. All boot catalog parameters described in El-Torito
|
||||
specs can be set and inquired. This was needed to use GRUB boot images
|
||||
for EFI.

||||
libburn-1.0.0.pl00 is now willing to create stdio-drive files with
|
||||
rw-permissions for all, if umask really asks for it. cdrskin now refuses
|
||||
to burn if the foreseeable size exceeds media capacity
|
||||
libisoburn-1.0.0.pl00 can now create an ISO 9660:1999 directory tree,
|
||||
improved the emulation fidelity of command -as mkisofs, lowered the default
|
||||
abort threshold for xorriso batch mode, and increased that threshold for
|
||||
xorriso dialog mode.
|
||||
|
||||
- Wed Feb 23 2011 release 1.0.2:
|
||||
libisofs fixes several bugs and introduces the capability to copy files
|
||||
inside the ISO filesystem.
|
||||
libburn removed a compilation obstacle on Solaris 9 and improved recognition
|
||||
of stdio pseudo-drives.
|
||||
libisoburn and xorriso fix bugs and make use of the new libisofs capability.
|
||||
xorriso improves its mkisofs emulation.
|
||||
|
||||
- Thu Mar 10 2011 release 1.0.4:
|
||||
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
|
||||
|
||||
- Mon Mar 18 2013 release 1.2.8:
|
||||
Some rarely occuring bugs were fixed in libisofs and libburn. libburn's
|
||||
handling of incomplete sessions has been improved. xorriso's mkisofs
|
||||
emulation learned to set El Torito section id strings.
|
||||
|
||||
- Fri May 17 2013 release 1.3.0:
|
||||
Several bugs were fixed in the libraries and in xorriso. The recently
|
||||
introduced new boot preparation capabilities have been tested. New
|
||||
boot preparation options for GRUB2 were added.
|
||||
|
||||
- Fri May 31 2013 patch release libburn-1.3.0.pl01:
|
||||
cdrskin -msinfo on DVD and BD reported as old session start the same
|
||||
number as the next writable address.
|
||||
Regression introduced by version 1.2.8.
|
||||
|
||||
- Fri Aug 07 2013 release 1.3.2:
|
||||
cdrskin has aquired the capability to copy audio tracks to .wav files.
|
||||
It can extract CD-TEXT in a form that is readable for humans and for
|
||||
cdrskin itself. Several small bugs were fixed in xorriso. Its capabilities
|
||||
to serve frontend programs in dialog mode have been improved.
|
||||
|
||||
- Thu Dec 12 2013 release 1.3.4:
|
||||
A long standing hidden bug was fixed, which affected inspection of
|
||||
unformatted DVD+RW.
|
||||
xorriso now by default puts EL Torito boot images to low block addresses.
|
||||
It can report and set read speeds. Several rarely occuring bugs were fixed.
|
||||
|
||||
- Tue Mar 04 2014 release 1.3.6
|
||||
libburn learned to operate optical drives and media on NetBSD. libisofs got
|
||||
a bug fix about HFS+ and enhancements about character set conversion.
|
||||
Minor bugs were fixed in libisoburn. xorriso can now find files with names
|
||||
which cannot be represented unchanged in ECMA-119, Joliet, or HFS+.
|
||||
|
||||
- Sat Jun 28 2014 release 1.3.8
|
||||
libburn got several bugs fixed. libisofs offers new API calls for inspection
|
||||
of boot sectors in ISO 9660 filesystems. xorriso improved its support for
|
||||
NetBSD, offers new features with command -find, and a command to extract
|
||||
ISO 9660 file content onto standard output or into filter processes.
|
||||
|
||||
- Sun May 17 2015 release 1.4.0
|
||||
This release is mainly about bug fixes and a new feature of xorriso to
|
||||
propose commands or as_mkisofs options which can reproduce the boot
|
||||
equipment of the loaded ISO filesystem.
|
||||
|
||||
- Sat Nov 28 2015 release 1.4.2
|
||||
libburn got some bugs fixed and learned to inquire the drive serial number.
|
||||
libisofs now sorts data file content by ECMA-119 file names for better
|
||||
reproducability of ISO content. Rock Ridge filenames may be restricted to
|
||||
lengths between 64 and 255 bytes. If needed, a qualified truncation happens.
|
||||
xorriso now can replay boot settings when modifying ISO filesystems.
|
||||
In order to avoid clogging of concurrent Linux SG_IO, xorriso got command
|
||||
-modesty_on_drive to enable an old workaround from IDE master/slave days.
|
||||
The source code underwent a scan by Coverity. About 150 code changes
|
||||
resulted, but no easy-to-trigger bugs were found.
|
||||
|
||||
- Fri Jan 29 2016 patch release libburn-1.4.2.pl01:
|
||||
cdrskin did not work with "-" (stdin) as input.
|
||||
Regression introduced by version 1.4.2.

On top of libburn there is implemented cdrskin 0.2.2, 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 .
|
||||
We will keep copyright narrow but will of course acknowledge valuable
|
||||
contributions in a due way.
|
||||
|
||||
cdrskin is a limited cdrecord compatibility wrapper which allows to use
|
||||
most of the libburn features from the command line.
|
||||
|
||||
Currently it is fully supported on GNU/Linux with kernels >= 2.4, on FreeBSD,
|
||||
on OpenSolaris, and on NetBSD.
|
||||
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
|
||||
"This software is provided as is. There is no warranty implied and ..."
|
||||
I used it on my own risk with :
|
||||
SuSE 7.2, kernel 2.4.4, ide-scsi emulation, LITE-ON LTR48125S CD burner
|
||||
SuSE 9.0, kernel 2.4.21, ide-scsi emulation, LG GSA-4082B CD/DVD burner
|
||||
RIP-14.4, kernel 2.6.14, no ide-scsi, with both above burners
|
||||
|
||||
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.
|
||||
Other people sucessfully tested cdrskin on several kernel 2.6 based x86 Linux
|
||||
systems, including 64 bit systems. (Further reports are welcome.)

go into the toplevel directory of the snapshot (e.g. cd libburn_pykix ),

and execute the autotools script ./bootstrap . Use autools version >= 1.7 .
|

./configure --prefix=/usr

Within that toplevel directory of either cdrskin-0.2.2 or libburn then execute:
|

./configure

This will already produce a cdrskin binary. But it will be necessary to
|

install libburn in order to use this binary.
|

(Note: there are next-level directories "libburn" and "cdrskin". Those
|

would be the wrong ones. Meant is the highest directory of tarball resp.

This will already produce a cdrskin binary. But it might be necessary to

beyond the scope of cdrskin. For this, see included libburn docs.

On FreeBSD, device rw-permissions are to be set in /etc/devfs.rules.
|
||||
On Solaris, pfexec privileges may be restricted to "basic,sys_devices".
|
||||
On NetBSD, rw-permission may be granted by chmod a+rw /dev/rcd?d.
|
||||
See below "System Dependend Drive Permission Examples".
|
||||
chmod a+rw /dev/sg0 /dev/sg1
|
||||
|
||||
(The CD-ROM is in these examples only for demonstrating the presence of another
|
||||
SCSI device. This /dev/sg0 may be left as it is and stay invisible for normal
|
||||
users.)
|
||||
|
||||
I strongly discourage to run cdrskin with setuid root or via sudo !
|
||||
It is not checked for the necessary degree of hacker safety.

Better consider to grant the necessary permissions to group "floppy"
|

and to add users to it.

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
|
||||
|
||||
|
||||
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.

||||
|
||||

|
||||
If you have use cases for them, please report your wishes and expectations.
|
||||
The convenient burn mode TAO is not available with libburn yet.
|
||||
Therefore it has to be defaulted to mode SAO which needs to know the track
|
||||
size in advance. non-cdrecord option tao_to_sao_tsize=650m causes each CD
|
||||
to get burned up to 650 MB regardless of the payload size.
|
||||
|
||||
On the other hand, the capability of multi-session and of writing streams
|
||||
of unpredicted lenght surpass the current DVD capabilities of cdrecord.
|
||||
Audio features are incomplete in respect to cdrecord. Well prepaired track
|
||||
files should get burned flawlessly, thanks to Lorenzo Taylor.
|
||||
Builtin extraction of raw audio data from filetypes .au and .wav is not
|
||||
implemented yet. See chapter "Audio CD" for details.
|
||||
|
||||
No multi session yet ... Please report your wishes.

|
||||
Inspiration and Standard
|
||||
|
||||
cdrskin combines the command line interface standard set by cdrecord with
|
||||
libburn, which is a control software for optical drives according to standard
|
||||
MMC-5. For particular CD legacy commands, standards MMC-3 and MMC-1 apply.
|
||||
|
||||
For the original meaning of cdrecord options see :
|
||||
man cdrecord
|
||||
(http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html)
|
||||
Do not bother Joerg Schilling with any cdrskin problems.
|
||||
(Be cursed if you install cdrskin as "cdrecord" without clearly forwarding
|
||||
this "don't bother Joerg" demand.)
|
||||
|
||||
this "don't bother Joerg" demand.)
|
||||
cdrskin does not contain any bytes copied from cdrecord's sources. Many bytes
|
||||
have been copied from the message output of cdrecord runs, though. I am
|
||||
thankful to Joerg Schilling for every single one of them.
|
||||
|
||||
Actually i, Thomas Schmitt, am a devoted user of cdrecord via my project
|
||||
scdbackup which still runs a bit better with cdrecord than with cdrskin. TAO.
|
||||
I have the hope that Joerg feels more flattered than annoyed by cdrskin.
|
||||
|
||||
Many thanks to Andy Polyakov for his dvd+rw-tools

||||
|
||||
Pseudo-SCSI Adresses
|
||||
|
||||
cdrecord and cdrskin share only some syntax of addresses but not the meaning
|
||||
of the components. A cdrecord-style address for cdrskin
|
||||
[[prefix:]scsibus,]target,lun
|
||||
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, "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.
|
||||
|
||||
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.
|
||||
To direct such callers to the appropriate drives, cdrskin allows to define
|
||||
device address aliases. Like
|
||||
cdrskin dev_translation=+1,0,0+/dev/sg1 \
|
||||
dev_translation=+ATA:1,0,0+/dev/sg1 \
|
||||
dev_translation=-"cd+dvd"-1,1,0 \
|
||||
...
|
||||
Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
|
||||
/dev/sg1 resp. to its standard alias 1,1,0.
|
||||
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/sg1
|
||||
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.
|
||||
|
||||
|
||||
Startup Files
|
||||
|
||||
If not --no_rc is the first argument then cdrskin attempts on startup to read
|
||||
arguments from the following three files:
|
||||
/etc/default/cdrskin
|
||||
/etc/defaults/cdrskin
|
||||
/etc/opt/cdrskin/rc
|
||||
/etc/cdrskin/cdrskin.conf
|
||||
$HOME/.cdrskinrc
|
||||
The files are read in the sequence given above.
|
||||
Each readable line is treated as one single argument. No extra blanks.
|
||||
A first character '#' marks a comment, empty lines are ignored.
|
||||
Each readable line is treated as one single argument. No extra blanks,
|
||||
no comments, no empty lines are permitted.
|
||||
|
||||
Example content of a startup file:

||||
# This is the default device
|
||||
dev=0,1,0
|
||||
|
||||
# Some more options
|
||||
fifo_start_at=0
|
||||
dev=1,1,0
|
||||
dev_translation=+1,0,0+1,1,0
|
||||
--fifo_start_empty
|
||||
fs=16m

||||
Audio CD
|
||||
|
||||
Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat
|
||||
results with audio data files which are :
|
||||
headerless PCM (i.e. uncompressed)
|
||||
44100 Hz sampling rate
|
||||
16 bits per sample
|
||||
stereo (2 channels)
|
||||
little-endian byte order with option -swab, or big-endian without -swab
|
||||
|
||||
Files with name extension .wav get examined wether they are in Microsoft WAVE
|
||||
format with above parameters and eventually get extracted by cdrskin itself.
|
||||
In the same way files with name extension .au get examined wether they are
|
||||
in SUN's audio format. For both formats, track format -audio and eventual
|
||||
endianness option -swab are enabled automatically.
|
||||
|
||||
Any other formats are to be converted to format .wav with above parameters
|
||||
or to be extracted as raw CD track data by commands like those given above
|
||||
under "Usage examples". Those raw files need option -audio and in most cases
|
||||
option -swab to mark them as little-endian/Intel/LSB-first 16-bit data.
|
||||
Incorrect endianness setting results in random noise on CD.
|
||||
Builtin extraction of raw audio data from filetypes .au and .wav is not
|
||||
implemented yet. Lorenzo Taylor enabled option -audio in cdrskin (thanks !)
|
||||
and reports neat results with audio data files which are :
|
||||
headerless
|
||||
44100Hz
|
||||
16bit, stereo (or 4-channel if the 4-channel bit is set),
|
||||
little-endian byte order
|
||||
He proposes to extract them from usual audio formats by commands like
|
||||
given above under "Usage examples".
|
||||
|
||||
The existence of cdrecord-builtin .wav extraction seems to have
|
||||
hampered the development of a standalone stripping tool. If you know
|
||||
a command line that would do the trick, contact me or libburn.pykix.org .
|
||||
I myself am not into audio. So libburn-hackers@pykix.org might be the
|
||||
best address for suggestions, requests and bug reports.
|
||||
|
||||
|
||||
DVD+RW , DVD-RAM , BD-RE
|
||||
|
||||
These random access media get treated as blank media regardless wether they
|
||||
hold data or not. Options -audio and -multi are not allowed. Only one track
|
||||
is allowed. -toc does not return information about the media content.
|
||||
Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second) or BD units
|
||||
(1x = 4,495,625 bytes/second). Currently there is no difference between -sao
|
||||
and -tao. If ever, then -tao will be the mode which preserves the current
|
||||
behavior.
|
||||
|
||||
BD-RE media need formatting before first use. cdrskin option "blank=as_needed"
|
||||
recognizes unformatted BD-RE and applies a lengthy formatting run.
|
||||
|
||||
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
|
||||

DVD-RW , DVD-R , DVD-R DL
|
||||
|
||||
DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
|
||||
"Sequential Recording". DVD-R are always in sequential state. DVD-R DL are
|
||||
always sequential and incapable of multi-session.
|
||||
|
||||
"Sequential" is the state of unused media and of media previously blanked
|
||||
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
|
||||
The according cdrskin option is blank=deformat_sequential .
|
||||
If "Incremental Streaming" is available, then sequential media are capable
|
||||
of multi-session like CD-R[W]. (But not capable of -audio recording.)
|
||||
This means they need option -multi to stay appendable, need to be blanked
|
||||
to be writeable from start, return useable info with -toc and -msinfo,
|
||||
eventually perform appending automatically.
|
||||
Without Incremental Streaming offered by the drive, only write mode DAO is
|
||||
available with sequential DVD-R[W]. It only works with blank media, allows only
|
||||
one single track, no -multi, and demands a fixely predicted track size.
|
||||
(growisofs uses it with DVD-R[W] if option -dvd-compat is given.)
|
||||
|
||||
Overwriteable DVD-RW behave much like DVD+RW. "Restricted" refers only to the
|
||||
granularity of random access and block size which have always to be aligned to
|
||||
full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by
|
||||
cdrskin dev=... -v blank=format_overwrite
|
||||
(Command dvd+rw-format -force can achieve Restricted Overwrite, too.)
|
||||
|
||||
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
|
||||
from the drive and last several minutes. Depending on mutual compatibility of
|
||||
drive and media, formatting can yield unusable media. It seems that those die
|
||||
too on blanking by cdrecord, dvd+rw-format or cdrskin. Perils of DVD-RW.
|
||||
|
||||
There are three DVD-RW formatting variants with cdrskin currently:
|
||||
|
||||
blank=format_overwrite uses "DVD-RW Quick" formatting (MMC-type 15h)
|
||||
and writes a first session of 128 MiB. This leads to media which are expandable
|
||||
and random addressable by cdrskin.
|
||||
|
||||
blank=format_overwrite_quickest uses "DVD-RW Quick" formatting (type 15h) too,
|
||||
but leaves the media in "intermediate" state. In the first session of writing
|
||||
one may only write sequentially to such a DVD. After that, it gets random
|
||||
addressable by cdrskin. DVD-ROM drives might show ill behavior with them.
|
||||
|
||||
blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
|
||||
This formatting lasts as long as writing a full DVD. It includes writing of
|
||||
lead-out which is said to be good for DVD ROM compatibility.
|
||||
|
||||
De-formatting options are available to make overwriteable DVD-RW sequential:
|
||||
|
||||
blank=deformat_sequential performs thorough blanking of all states of DVD-RW.
|
||||
blank=all and blank=fast perform the same thorough blanking, but refuse to do
|
||||
this with overwriteable DVD-RW, thus preserving their formatting. The specs
|
||||
allow minimal blanking but the resulting media on my drives offer no
|
||||
Incremental Streaming afterwards. So blank=fast will do full blanking.
|
||||
|
||||
blank=deformat_sequential_quickest is faster but might yield DAO-only media.
|
||||
|
||||
|
||||
DVD+R , DVD+R DL , BD-R
|
||||
|
||||
From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
|
||||
into an own session, though.
|
||||
|
||||
DVD+R DL appear as extra large DVD+R. cdrskin does not allow to set the address
|
||||
of the layer break where a reading drive might show some delay while switching
|
||||
between both media layers.
|
||||
|
||||
BD-R are sold unformatted blank. If used without initial formatting then the
|
||||
drive is supposed to format them to maximum payload size with no Defect
|
||||
Management (see also above with BD-RE).
|
||||
If Defect Management is desired then BD-R need to be formatted before the
|
||||
first attempt to write a session to them.
|
||||
blank=format_if_needed will detect the situation and eventually apply
|
||||
default sized Defect Management formatting.
|
||||
blank=format_defectmgt_* will apply non-default parameters to formatting.
|
||||
|
||||
|
||||
Emulated Drives
|
||||
|
||||
cdrskin can use filesystem objects as emulated drives. Regular files or block
|
||||
devices appear similar to DVD-RAM. Other file types resemble blank DVD-R.
|
||||
Necessary precondition is option --allow_emulated_drives which is not accepted
|
||||
if cdrskin took another user identity because of the setuid bit of its access
|
||||
permissions.
|
||||
Addresses of emulated drives begin with prefix "stdio:". E.g.
|
||||
dev=stdio:/tmp/my_pseudo_drive
|
||||
|
||||
For safety reasons the superuser is only allowed to use /dev/null as emulated
|
||||
drive. See man page section FILES for a way to lift that ban.
|
||||
|
||||

||||

|
||||
|
||||
Special compilation variations
|
||||
|
||||
All following options of ./configure and cdrskin/compile_cdrskin.sh are
|
||||
combinable. After runs of ./configure do as next:
|
||||
make clean ; make
|
||||
|
||||
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 cdrskin option dvd_obs=64k will yield even better performance in
|
||||
such a situation. 64k can be made default at compile time by
|
||||
cdrskin/compile_cdrskin.sh -dvd_obs_64k
|
||||
It can also be enabled at configure time by
|
||||
./configure ... --enable-dvd-obs-64k ...
|
||||
|
||||
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
|
||||
Add option
|
||||
-use_libcdio
|
||||
to your run of cdrskin/compile_cdrskin.sh .
|
||||
|
||||
You may get a (super fat) statically linked binary by :
|
||||
cdrskin/compile_cdrskin.sh -static
|
||||

Linux only:
|

|

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"

System Dependend Drive Permission Examples
|
||||
|
||||
Accessing the optical drives requires privileges which usually are granted
|
||||
only to the superuser. Linux, FreeBSD, Solaris, NetBSD, offer quite different
|
||||
approaches for avoiding the need for unrestricted privileges.
|
||||
|
||||
First check whether some friendly system setting already allows you to
|
||||
access the drives as normal user:
|
||||
cdrskin --devices
|
||||
Those drives of which you see address and type strings are already usable.
|
||||
|
||||
If there remain drives invisible which the superuser can see by the same
|
||||
command, then the following examples might help:
|
||||
|
||||
---------------
|
||||
On all systems:
|
||||
---------------
|
||||
Add the authorized users of CD drives to group "floppy" in /etc/group.
|
||||
If missing: create this group.
|
||||
Changes to /etc/group often only affect new login sessions. So log out and in
|
||||
before making the first tests.
|
||||
|
||||
---------
|
||||
On Linux:
|
||||
---------
|
||||
Allow rw-access to the drives
|
||||
chgrp floppy /dev/sr0 /dev/sr1
|
||||
chmod g+rw /dev/sr0 /dev/sr1
|
||||
It might be necessary to perform chgrp and chmod after each reboot or to
|
||||
edit distro dependent device configuration files for permanent settings.
|
||||
|
||||
-----------
|
||||
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.
|
||||
|
||||
----------
|
||||
On NetBSD:
|
||||
----------
|
||||
Allow rw-access to the drives
|
||||
chgrp floppy /dev/rcd[01]d
|
||||
chmod g+rw /dev/rcd[01]d

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

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

<DT>The most common options of cdrecord for data and audio on CD media

On all DVD media, cdrskin is able to perform any recording job

which is possible with cdrecord.

Other than with cdrecord, option -multi is supported with many DVD types and

BD-R. Write mode -tao works with anything but quickly blanked DVD-RW and

DVD-R DL, which both support no -multi.

cdrskin -scanbus or --devices hangs for quite a while if there is
|
||||
a CD drive which does not work properly (e.g. because it has individual
|
||||
problems with DMA).
|
||||
So if the superuser gets no result with cdrskin --devices then one should
|
||||
disable DMA with the problematic CD drives
|
||||
(like: <KBD>hdparm -d0 /dev/hdd</KBD> )
|
||||
and try again.<BR>
|
||||
In severe cases it might be necessary to guess the device name /dev/sgN resp.
|
||||
/dev/hdX of the non-ill burner if it cannot be found otherwise among its
|
||||
ill peers. Alternatively one can guess the address of the ill device, remove
|
||||
rw-permissions and retry the bus scan as non-superuser.
|
||||
<LI>
|
||||
Burners other than /dev/sg0 and /dev/hdX (i.e. without ide-scsi) need a user
|
||||
supplied device address for program eject.
|
||||
(Note: -eject is now working in libburn-0.2.1 SVN and the workaround described
|
||||
here is obsolete with cdrskin-0.1.5 as offered below.)

libburn and cdrskin are now mature enough to substitute cdrecord in its

major use cases of CD and DVD burning. It is possible to foist cdrskin on

various software packages if it gets falsely named "cdrecord".

I am aware that libburn and cdrskin still have way to go until you can simply

'''cdrskin is the cdrecord compatibility middleware of libburn.'''
|
||||
cdrskin is the cdrecord compatibility middleware of libburn.
|
||||
|
||||
Its paragon, 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. Currently it does CD-R and CD-RW this way.
|
||||
Overwriteable media DVD-RAM, DVD+RW, DVD-RW, and BD-RE are handled differently
|
||||
than with cdrecord-ProDVD in order to offer TAO-like single track recording.
|
||||
Sequential DVD-R[W], DVD+R, DVD+R DL, BD-R are handled like CD-R[W] with TAO
|
||||
and multi-session. Additionally cdrskin offers cdrecord-ProDVD-like mode DAO
|
||||
with DVD-R[W].
|
||||
traditionally provided by cdrecord. Currently it does CD-R and CD-RW.
|
||||
Its future ability to burn DVD media depends on the development of libburn.
|
||||
|
||||
cdrskin does not contain any bytes copied from cdrecord's sources.
|
||||
Many bytes have been copied from the message output of cdrecord
|
||||
runs, though. The most comprehensive technical overview of cdrskin
|
||||
can be found in [http://libburnia-project.org/browser/libburn/trunk/cdrskin/README?format=txt cdrskin/README].
|
||||
can be found in cdrskin/README .

|
||||
|
||||
cdrskin with CD media fails to match its paragon cdrecord on three major
|
||||
fields: convenient TAO burn mode, multi session, audio features.
|
||||
|
||||
Audio features are the only topic where cdrskin did not yet exploit current
|
||||
libburn to the maximum. This is due to my own lack of audiophile motivation
|
||||
and due to the lack of sincere users who provide me with cdrecord use cases,
|
||||
help me to explore the original cdrecord behavior and serve as dedicated
|
||||
testers for eventual newly introduced cdrskin audio features.
|
||||
|
||||
cdrskin does not provide DVD burning yet. See advise to use dvd+rw-tools

||||
at the end of this text.

About the command line options of cdrskin:
|
||||
|
||||
They are described in detail in [http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html#OPTIONS section OPTIONS] of
|
||||
[http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html man cdrskin]
|
||||
|
||||
There are two families of options: cdrecord-compatible ones and options
|
||||
which are specific to cdrskin. The latter are mostly used to configure
|
||||
cdrskin for its task to emulate cdrecord. There are some, nevertheless,
|
||||
which provide rather exotic unique features of cdrskin.
|
||||
|
||||
The cdrecord-compatible options are listed in the output of
|
||||
{{{
|
||||
cdrskin -help
|
||||
}}}
|
||||
where the option "help" has *one* dash. Online: [http://scdbackup.sourceforge.net/cdrskin_help_devel cdrskin -help]
|
||||
|
||||
cdrskin -help
|
||||
|
||||
where the option "help" has *one* dash.
|
||||
For these options you may expect program behavior that is roughly the
|
||||
same as described in original man cdrecord .
|
||||
same as described in original man 1 cdrecord .
|
||||
|
||||
Online: http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html

||||
The cdrskin-specific options are listed by
|
||||
{{{
|
||||

|
||||
}}}
|
||||
where the option "help" has *two* dashes. Online: [http://scdbackup.sourceforge.net/cdrskin__help_devel cdrskin --help]
|
||||
|
||||
Some are very experimental and should only be
|
||||
used in coordination with the libburnia developer team.

--devices can be used by the sysadmin to scan the system for possible drives
|
||||
--devices allows the sysadmin to scan the system for possible drives
|
||||
and displays their detected properties.
|
||||
The drives are listed one per line, with fields:
|
||||
libburn-drive-number, sysadmin-device-file, permissions, vendor, type

|
||||
If this is not possible, e.g. because the media is written and not
|
||||
re-usable, then the program run fails.
|
||||
|
||||
Option blank= offers several specialized blanking and formatting types,
|
||||
which one may use for particular purposes on DVD-RW, DVD-RAM and BD-RE.
|
||||
(See also below: blank=format_overwrite)
|
||||
The drive offers a list of possible formats by cdrskin option --list_formats.
|
||||
One should aquire MMC background information before making use of them.
|
||||
eject_device=<path> is needed to work around yet broken tray ejection of
|
||||
drives. cdrskin makes a bold shell call to program "eject" and regrettably
|
||||
this program does not like our addresses for SCSI devices.
|
||||
/dev/hdX work fine and /dev/sg0 is quite safely guess-translated to
|
||||
/dev/sr0 . /dev/sg1 et.al. need the user's help. <path> must work with eject.
|
||||
|
||||
--------------------------------------------------------------------------
|
||||
|
||||
cdrskin does not only read from and write to optical drives which comply
|
||||
to the MMC standard but also does the same with regular files or block
|
||||
devices other than optical drives.
|
||||
dev_translation=<sep><from><sep><to> is needed to foist cdrskin to frontend
|
||||
programs of cdrecord which do *not* ask cdrecord -scanbus but which make
|
||||
own assumptions and guesses about cdrecord's device addresses.
|
||||
cdrskin project - at least for now - refuses to try to provide a similar
|
||||
guesswork but uses own cdrecord style addresses which have a mere
|
||||
semi-automatic text mapping to real libburn addresses. See cdrskin/README,
|
||||
"Pseudo-SCSI Adresses".
|
||||
|
||||
Because the power to alter a disk file might be a bad surprise for a
|
||||
traditional user of cdrecord, it is necessary to give option
|
||||
--allow_emulated_drives before an emulated drive may be addressed.
|
||||
Eventually one of the startup files would be a good place for it.
|
||||
See man page, section FILES.
|
||||
If you need to foist cdrskin under a frontend then you may be lucky and
|
||||
both ideas of an address coincide. Especially if the frontend has the
|
||||
decency to ask its "cdrecord" via option -scanbus for a list of drives.
|
||||
If not, look into the error protocol of the frontend, look at the output
|
||||
of a run of cdrskin --devices and give cdrskin the necessary hint.
|
||||
|
||||
The addresses of emulated drives begin with the prefix "stdio:".
|
||||
{{{
|
||||
dev=stdio:/tmp/pseudo_drive
|
||||
dev=stdio:/dev/usbstick
|
||||
}}}
|
||||
If your frontend insists in using "0,0,0" and --devices reported
|
||||
dev='/dev/sg0' resp. cdrskin -scanbus reported "1,0,0" then this
|
||||
would be the appropriate translation
|
||||
|
||||
Regular files and block devices behave much like DVD-RAM.
|
||||
|
||||
Other file types may be valid targets for write-only operations.
|
||||
This includes standard output, named pipes, character devices
|
||||
{{{
|
||||
dev=stdio:/dev/fd/1
|
||||
dev=stdio:/tmp/named_pipe
|
||||
dev=stdio:/dev/ptyxy
|
||||
}}}
|
||||
dev_translation=+0,0,0+/dev/sg0
|
||||
|
||||
These files behave much like blank DVD-R.
|
||||
The "+" character is a separator to be choosen by you.
|
||||
Currently i am not aware of the need to choose any other than "+"
|
||||
unless you get playful with custom translations like
|
||||
|
||||
All files used as pseudo-drives have to offer rw-permission.
|
||||
dev_translation=-"cd+dvd"-1,0,0

|

|
||||
The DVD capabilities of cdrskin differ from those of cdrecord-ProDVD. cdrskin
|
||||
offers TAO-like multi-session with DVD-R[W], DVD+R[ DL] and TAO-like single
|
||||
session with overwriteable DVD media. It also offers DAO on DVD-R[W] which is
|
||||
probably the same as the traditional cdrecord-ProDVD write mode.
|
||||
|
||||
Non-cdrecord blank mode blank=format_overwrite brings a DVD-RW
|
||||
disc from its initial profile "Sequential Recording" into profile state
|
||||
"Restricted Overwrite".
|
||||
{{{
|
||||
cdrskin dev=/dev/sr0 -v blank=format_overwrite
|
||||
}}}
|
||||
|
||||
DVD-RAM, DVD+RW, BD-RE and overwriteable DVD-RW appear to cdrskin as blank
|
||||
media which are capable of taking only a single track. This track may be
|
||||
positioned on a 32KiB aligned address, though.
|
||||
{{{
|
||||
cdrskin ... write_start_address=2412m ...
|
||||
}}}
|
||||
|
||||
Non-cdrecord blank mode blank=deformat_sequential brings an overwriteable
|
||||
DVD-RW back into state "Sequential Recording" with the capability of doing
|
||||
multi-session, if the drive is capable of "Incremental Streaming"
|
||||
(MMC feature 21h).
|
||||
|
||||
Used sequential DVD-RW media may be blanked by blank=fast or blank=all which
|
||||
normally both do full blanking. Thus sequential DVD-RW behave much like large
|
||||
CD-RW with possibly more than 99 tracks.
|
||||
|
||||
blank=deformat_sequential does minimal blanking of DVD-RW which usually yields
|
||||
media incapable of "Incremental Streaming".
|
||||
|
||||
Option --prodvd_cli_compatible activates blank=fast and blank=all for
|
||||
overwriteable DVD-RW which normally ignore those two options. It also makes
|
||||
option -multi tolerable with media and write modes which are not suitable for
|
||||
multi-session. (The default behavior of cdrskin deems me to be preferrable.)
|
||||
|
||||
Option --grow_overwriteable_iso gives cdrskin ISO pseudo-multi-session
|
||||
capabilities on DVD-RAM, DVD+RW, BD-RE similar to growisofs.
|
||||
Associated options blank=, -multi, -msinfo and -toc are available in this case.
|
||||
They either pretend a blank media (if there is no ISO 9660 image) or appendable
|
||||
media with a single session and track on it. blank= invalidates ISO images.

assert_write_lba=<lba> ensures that the start block address which

was used with the formatter program (e.g. mkisofs -C) matches the start block
|
||||
address which will be used by the upcoming burn.

E.g. cdrskin aborts with an error message if
|
||||
{{{

is given but an appendable media is to be burned which would start at

An ISO-9660 file system image must be prepared according to a particular

|

do not match then the filesystem will not be mountable or may even cause system
|
||||
trouble.

A sequential archive format like afio or star will not necessarily need such

Advanced multi-session use cases as of dvd+rw-tools:
|
||||
DVD advise:
|
||||
|
||||
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.
|
||||
For burning of DVD media the cdrskin project currently advises to use
|
||||
Andy Polyakov's dvd+rw-tools which despite their historic name burn
|
||||
for me on above burner: DVD+RW, DVD+R, DVD-RW, DVD-R .
|
||||
|
||||
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.
|
||||
http://fy.chalmers.se/~appro/linux/DVD+RW/tools
|
||||
|
||||
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].
|
||||
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).
|
||||
|
||||
See [http://scdbackup.sourceforge.net/man_1_xorriso.html man xorriso].
|
||||
If there is sincere and well motivated interest, the cdrskin project could try
|
||||
to employ growisofs as DVD burning engine. The cdrskin project would prefer to
|
||||
wait for DVD support being included in libburn, though.
|
||||
A very limited and specialized cdrecord-compatibility wrapper for growisofs
|
||||
serves in my project scdbackup. It is not overly hard to make one that serves
|
||||
some very few fixed use cases.
|
||||
|
||||
To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
|
||||
they would write to a traditional tape device. Try old tape archiver
|
||||
commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
|
||||
I have heard rumors that DVD-RW in mode "restricted overwrite" would be
|
||||
block device ready, too. My burner is not a real friend of DVD-RW and
|
||||
in an experiment the burn worked fine - but the result was not identical
|
||||
to the stream sent to the device. I had similar failure with DVD-RAM, too.
|
||||
|
||||
Beware of the impact of a slow block device on overall system i/o buffering.
|
||||
It is wise to curb its input to a speed which it is able to deliver to media.
|
||||
Else your i/o dedicated RAM might buffer a big amount of stream data.

|
||||
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, and 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.
|
||||
The Sony .TOC example:
|
||||
A0 01
|
||||
A1 14
|
||||
A2 63:02:18
|
||||
01 00:02:00
|
||||
02 04:11:25
|
||||
03 08:02:50
|
||||
04 11:47:62
|
||||
...
|
||||
13 53:24:25
|
||||
14 57:03:25
|
||||
yields
|
||||
88 00 23 00 01 0e 00 3f 02 12 00 00 00 00 00 00 12 00
|
||||

|
||||
|
||||
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 07 2a 00 03 04 00 00 00 00 1c 1e 27 1c 2a 1e 72 20
|
||||
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 array 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 of text packs 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:
|
||||

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);
|
||||
|
||||
and a writer which converts an array of text packs to such a Sony Input Sheet:
|
||||
|
||||
int burn_make_input_sheet_v07t(unsigned char *text_packs, int num_packs,
|
||||
int start_tno, int track_count,
|
||||
char **result, int *char_code, 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);
|
||||
|
||||
int burn_track_set_isrc_string(struct burn_track *t, char isrc[13],
|

int flag);

|

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

Text Data Copy Protection = Copyright value for pack type 0x8f
|
||||
"ON" = 0x03, "OFF" = 0x00
|
||||
First Track Number = The lowest track number used in the file
|
||||
Last Track Number = The highest track number used in the file
|

Remarks = Comments with no influence on CD-TEXT
|
||||
Disc Information NN = Supplementary information for use by record companies.
|
||||
ISO-8859-1 encoded. NN ranges from 01 to 04.
|
||||
Input Sheet Version = "0.7T"
|
||||
|
||||
|
||||
libburn peculiarties:
|
||||
|
||||
libburn may read files of the described format by
|
||||
burn_session_input_sheet_v07t()
|
||||
after the burn_session has been establiched and all burn_track objects have
|
||||
been added. It can convert an array of CD-TEXT packs into this format by
|
||||
burn_make_input_sheet_v07t()
|
||||
|
||||
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.)

|
||||
A CDRWIN cue sheet file defines the track data source (FILE), various text
|
||||
attributes (CATALOG, TITLE, PERFORMER, SONGWRITER, ISRC), track block types
|
||||
(TRACK), track start addresses (INDEX).
|
||||
The rules for CDRWIN cue sheet files are described at
|
||||
http://digitalx.org/cue-sheet/syntax/
|

@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.
|
||||
Libburn is an open-source library for reading, mastering and writing
|
||||
optical discs. For now this means only CD-R and CD-RW.
|
||||
|
||||
Our scope is currently Linux 2.4 and 2.6, FreeBSD, OpenSolaris, or NetBSD.
|
||||
For ports to other systems we would need : login on a development machine or
|
||||
an OS that 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.
|
||||
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.
|
||||
|
||||
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.
|
||||
Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
|
||||
this for now, because of our history. The project could need advise from or
|
||||
membership of skilled kernel people and people who know how to talk CD/DVD
|
||||
drives into doing things.
|
||||
|
||||
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.
|
||||
We do have a workable code base for burning data CDs, though. The burn API is
|
||||
quite comprehensively documented and can be used to build a presentable
|
||||
application.
|
||||
We do have a functional binary which emulates parts 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.
|
||||
|
||||
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.
|
||||
@subsection components The project components (list subject to growth, hopefully):
|
||||
|
||||
SONAME:
|
||||
libburn.so.4 (since 0.3.4, March 2007),
|
||||
- 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/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation.
|
||||
|
||||
- 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.

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 main API example of libburn
|
||||
is named test/libburner.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.

libburner is a minimal demo application for the library libburn
|
||||
(see: libburn/libburn.h) as provided on http://libburnia-project.org .
|
||||
It can list the available devices, can burn to recordable CD, DVD, or BD,
|
||||
can blank a CD-RW or DVD-RW, and can format unformatted DVD-RW, BD-R, or BD-RE.

|
||||
To be read from *not mounted* CD via:
|
||||
afio -tvZ /dev/hdc
|
||||
Program tar would need a clean EOF which our padded CD cannot deliver.
|
||||
</pre>
|
||||
libburner has two companions, telltoc and dewav, which help to perform some
|
||||
peripheral tasks of burning.
|
||||
|
||||
telltoc prints a table of content (sessions, tracks and leadouts), it tells
|
||||
about type and state of media, and also is able to provide the necessary
|
||||
multi-session information for program mkisofs option -C. Especially helpful
|
||||
are its predictions with "Write multi" and "Write modes" where availability
|
||||
of "TAO" indicates that tracks of unpredicted length can be written.
|
||||
See: test/telltoc --help.
|
||||
|
||||
dewav extracts raw byte-swapped audio data from files of format .wav (MS WAVE)
|
||||
or .au (SUN Audio). See example in libburner --help.

We do have a functional binary which emulates parts 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/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation.
|
||||
|
||||
- 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
|
||||
Schilling's cdrtools. cdrskin strives to be a second source for
|
||||
the services traditionally provided by 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.
|
||||
|
||||
- "test" is a collection of application gestures and examples given by the
|
||||
authors of the library features. The main API example of libburn
|
||||
is named test/libburner.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
|
||||
its toplevel directory and execute
|
||||
|
||||
- ./bootstrap (needed if you downloaded from SVN)
|
||||
|
||||
- ./configure
|
||||
|
||||
- make
|
||||
|
||||
To make the libraries accessible for running resp. developing applications
|
||||
|
||||
- make install
|
||||
|
||||
Both libraries are written in C language and get built by autotools.
|
||||
Thus we expect them to be useable by a wide range of Linux-implemented
|
||||
languages and development tools.
|
||||
|
||||
|
||||
@section libburner Libburner
|
||||
|
||||
libburner is a minimal demo application for the library libburn
|
||||
(see: libburn/libburn.h) as provided on http://libburn.pykix.org .
|
||||
It can list the available devices, can blank a CD-RW and
|
||||
can burn to CD-R or CD-RW.
|
||||
|
||||
It's main purpose, nevertheless, is to show you how to use libburn and also
|
||||
to serve the libburn team as reference application. libburner does indeed
|
||||
define the standard way how above three gestures can be implemented and
|
||||
stay upward compatible for a good while.

||||

Users of modern desktop Linux installations report misburns with CD/DVD
|
||||
recording due to concurrency problems.
|
||||
|
||||
This text describes two locking protocols which have been developed by our
|
||||
best possible effort. But finally they rather serve as repelling example of
|
||||
what would be needed in user space to achieve an insufficient partial solution.
|
||||
|
||||
Ted Ts'o was so friendly to help as critic with his own use cases. It turned
|
||||
out that we cannot imagine a way in user space how to cover reliably the needs
|
||||
of callers of libblkid and the needs of our burn programs.
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||

|
||||
|
||||
The "Delicate Device Locking Protocol" shall demonstrate our sincere
|
||||
consideration of the problem.
|
||||
|
||||
"What are the Stumble Stones ?" lists reasons why the effort finally failed.
|
||||
|
||||
-----------------------------------------------------------------------------
|
||||
|
||||
|
||||
Delicate Device Locking Protocol
|
||||
(a joint sub project of cdrkit and libburnia)
|
||||
(contact: scdbackup@gmx.net )
|
||||
|
||||
Our projects provide programs which allow recording of data on CD or DVD.
|
||||
We encounter an increasing number of bug reports about spoiled burn runs and
|
||||
wasted media which obviously have one common cause: interference by other
|
||||
programs which access the drive's device files.
|
||||
There is some riddling about which gestures exactly are dangerous for
|
||||
ongoing recordings or can cause weirdly misformatted drive replies to MMC
|
||||
commands.
|
||||
We do know, nevertheless, that these effects do not occur if no other program
|
||||
accesses a device file of the drive while our programs use it.
|
||||
|
||||
DDLP shall help to avoid collisions between programs in the process of
|
||||
recording to a CD or DVD drive and other programs which access that drive.
|
||||
The protocol intends to provide advisory locking. So any good-willing program
|
||||
has to take some extra precautions to participate.
|
||||
|
||||
If a program does not feel vulnerable to disturbance, then the precautions
|
||||
impose much less effort than if the program feels the need for protection.
|
||||
|
||||
Two locking strategies are specified:
|
||||
DDLP-A operates on device files only. It is very Linux specific.
|
||||
DDLP-B adds proxy lock files, inspired by FHS /var/lock standard.
|
||||
|
||||
|
||||
DDLP-A
|
||||
|
||||
This protocol relies on the hardly documented feature open(O_EXCL | O_RDWR)
|
||||
with Linux device files and on POSIX compliant fcntl(F_SETLK).
|
||||
|
||||
Other than the original meaning of O_EXCL with creating regular files, the
|
||||
effect on device files is mutual exclusion of access. I.e. if one
|
||||
filedescriptor is open on that combination of major-minor device number, then
|
||||
no other open(O_EXCL) will succeed. But open() without O_EXCL would succeed.
|
||||
So this is advisory and exclusive locking.
|
||||
With kernel 2.6 it seems to work on all device drivers which might get used
|
||||
to access a CD/DVD drive.
|
||||
|
||||
The vulnerable programs shall not start their operation before they occupied a
|
||||
wide collection of drive representations.
|
||||
Non-vulnerable programs shall take care to detect the occupation of _one_ such
|
||||
representation.
|
||||
|
||||
So for Friendly Programs
|
||||
|
||||
A program which does not feel vulnerable to disturbance is urged to access
|
||||
CD/DVD drives by opening a file descriptor which will uphold the lock
|
||||
as long as it does not get closed. There are two alternative ways to achieve
|
||||
this.
|
||||
Very reliable is
|
||||
|
||||
open( some_path , O_EXCL | ...)
|
||||
|
||||
But O_EXCL imposes restrictions and interferences:
|
||||
- O_EXCL | O_RDONLY does not succeed with /dev/sg* !
|
||||
- O_EXCL cannot provide shared locks for programs which only want to lock
|
||||
against burn programs but not against their own peers.
|
||||
- O_EXCL keeps from obtaining information by harmless activities.
|
||||
- O_EXCL already has a meaning with devices which are mounted as filesystems.
|
||||
This priority meaning is more liberal than the one needed for CD/DV recording
|
||||
protection.
|
||||
|
||||
So it may be necessary to use a cautious open() without O_EXCL and to aquire
|
||||
a POSIX lock via fcntl(). "Cautious" means to add O_NDELAY to the flags of
|
||||
open(), because this is declared to avoid side effects within open().
|
||||
|
||||
With this gesture it is important to use the paths expected by our burn
|
||||
programs: /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
|
||||
because fcntl(F_SETLK) does not lock the device but only a device-inode.
|
||||
|
||||
std_path = one of the standard device files:
|
||||
/dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
|
||||
or a symbolic link pointing to one of them.
|
||||
open( std_path , ... | O_NDELAY)
|
||||
fcntl(F_SETLK) and close() on failure
|
||||
... eventually disable O_NDELAY by fcntl(F_SETFL) ...
|
||||
|
||||
There is a pitfall mentioned in man 2 fcntl :
|
||||
"locks are automatically released [...] if it closes any file descriptor
|
||||
referring to a file on which locks are held. This is bad [...]"
|
||||
So you may have to re-lock after some temporary fd got closed.
|
||||
|
||||
|
||||
Vulnerable Programs
|
||||
|
||||
For programs which do feel vulnerable, O_EXCL would suffice for the /dev/hd*
|
||||
device file family and their driver. But USB and SATA recorders appear with
|
||||
at least two different major-minor combinations simultaneously.
|
||||
One as /dev/sr* alias /dev/scd*, the other as /dev/sg*.
|
||||
The same is true for ide-scsi or recorders attached to SCSI controllers.
|
||||
|
||||
So, in order to lock any access to the recorder, one has to open(O_EXCL)
|
||||
not only the device file that is intended for accessing the recorder but also
|
||||
a device file of any other major-minor representation of the recorder.
|
||||
This is done via the SCSI address parameter vector (Host,Channel,Id,Lun)
|
||||
and a search on standard device file paths /dev/sr* /dev/scd* /dev/sg*.
|
||||
In this text the alternative device representations are called "siblings".
|
||||
|
||||
For finding them, it is necessary to apply open() to many device files which
|
||||
might be occupied by delicate operations. On the other hand it is very
|
||||
important to occupy all reasonable representations of the drive.
|
||||
So the reading of the (Host,Channel,Id,Lun) parameters demands an
|
||||
open(O_RDONLY | O_NDELAY) _without_ fcntl() in order to find the outmost
|
||||
number of representations among the standard device files. Only ioctls
|
||||
SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER are applied.
|
||||
Hopefully this gesture is unable to cause harmful side effects on kernel 2.6.
|
||||
|
||||
At least one file of each class sr, scd and sg should be found to regard
|
||||
the occupation as satisfying. Thus corresponding sr-scd-sg triplets should have
|
||||
matching ownerships and access permissions.
|
||||
One will have to help the sysadmins to find those triplets.
|
||||
|
||||
A spicy detail is that sr and scd may be distinct device files for the same
|
||||
major-minor combination. In this case fcntl() locks on both are needed
|
||||
but O_EXCL can only be applied to one of them.

An open and free implementation ddlpa.[ch] is provided as

|

The current version of this text is
|
||||
http://libburnia.pykix.org/browser/libburn/trunk/doc/ddlp.txt?format=txt
|
||||
|
||||
Put ddlpa.h and ddlpa.c into the same directory and compile as test program by
|
||||
cc -g -Wall -DDDLPA_C_STANDALONE -o ddlpa ddlpa.c
|
||||
|
||||
Use it to occupy a drive's representations for a given number of seconds
|
||||
./ddlpa /dev/sr0 300
|
||||
|
||||
It should do no harm to any of your running activities.
|
||||
If it does: Please, please alert us.
|
||||
|
||||
Your own programs should not be able to circumvent the occupation if they
|
||||
obey above rules for Friendly Programs.
|
||||
Of course ./ddlpa should be unable to circumvent itself.
|
||||
|
||||
A successfull occupation looks like
|
||||
DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/scd0") = "/dev/sr0"
|
||||
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
|
||||
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"
|
||||
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sg0"
|
||||
DDLPA_DEBUG: ddlpa_occupy() : '/dev/scd0'
|
||||
DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/sg0'
|
||||
DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/sr0'
|
||||
---------------------------------------------- Lock gained
|
||||
ddlpa: opened /dev/sr0
|
||||
ddlpa: opened siblings: /dev/scd0 /dev/sg0
|
||||
slept 1 seconds of 300
|
||||
|
||||
Now an attempt via device file alias /dev/NEC must fail:
|
||||
DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/NEC") = "/dev/sg0"
|
||||
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
|
||||
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"
|
||||
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sg0"
|
||||
Cannot exclusively open '/dev/sg0'
|
||||
Reason given : Failed to open O_RDWR | O_NDELAY | O_EXCL : '/dev/sr0'
|
||||
Error condition : 16 'Device or resource busy'
|
||||
|
||||
With hdc, of course, things are trivial
|
||||
DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/hdc") = "/dev/hdc"
|
||||
DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/hdc'
|
||||
---------------------------------------------- Lock gained
|
||||
ddlpa: opened /dev/hdc
|
||||
slept 1 seconds of 1
|
||||
|
||||
|
||||
Ted Ts'o provided program open-cd-excl which allows to explore open(2) on
|
||||
device files with combinations of read-write, O_EXCL, and fcntl().
|
||||
(This does not mean that Ted endorsed our project yet. He helps exploring.)
|
||||
|
||||
Friendly in the sense of DDLP-A would be any run which uses at least one of
|
||||
the options -e (i.e. O_EXCL) or -f (i.e. F_SETLK, applied to a file
|
||||
descriptor which was obtained from a standard device file path).
|
||||
The code is available under GPL at
|
||||
http://libburnia.pykix.org/browser/libburn/trunk/test/open-cd-excl.c?format=txt
|
||||
To be compiled by
|
||||
cc -g -Wall -o open-cd-excl open-cd-excl.c
|
||||
|
||||
Options:
|
||||
-e : open O_EXCL
|
||||
-f : aquire lock by fcntl(F_SETLK) after sucessful open
|
||||
-i : do not wait in case of success but exit 0 immediately
|
||||
-r : open O_RDONLY , with -f use F_RDLCK
|
||||
-w : open O_RDWR , with -f use F_WRLCK
|
||||
plus the path of the devce file to open.
|
||||
|
||||
Friendly Programs would use gestures like:
|
||||
./open-cd-excl -e -r /dev/sr0
|
||||
./open-cd-excl -e -w /dev/sg1
|
||||
./open-cd-excl -e -w /dev/black-drive
|
||||
./open-cd-excl -f -r /dev/sg1
|
||||
./open-cd-excl -e -f -w /dev/sr0
|
||||
|
||||
Ignorant programs would use and cause potential trouble by:
|
||||
./open-cd-excl -r /dev/sr0
|
||||
./open-cd-excl -w /dev/sg1
|
||||
./open-cd-excl -f -w /dev/black-drive
|
||||
where "/dev/black-drive" is _not_ a symbolic link to
|
||||
any of /dev/sr* /dev/scd* /dev/sg* /dev/hd*, but has an own inode.
|
||||
|
||||
Prone to failure without further reason is:
|
||||
./open-cd-excl -e -r /dev/sg1
|
||||
|
||||
|
||||
----------------------------------------------------------------------------
|
||||
|
||||
DDLP-B
|
||||
|
||||
This protocol relies on proxy lock files in some filesystem directory. It can
|
||||
be embedded into DDLP-A or it can be used be used standalone, outside DDLP-A.
|
||||
|
||||
DDLP-A shall be kept by DDLP-B from trying to access any device file which
|
||||
might already be in use. There is a problematic gesture in DDLP-A when SCSI
|
||||
address parameters are to be retrieved. For now this gesture seems to be
|
||||
harmless. But one never knows.
|
||||
Vice versa DDLP-B may get from DDLP-A the service to search for SCSI device
|
||||
file siblings. So they are best as a couple.
|
||||
|
||||
But they are not perfect. Not even as couple. fcntl() locking is flawed.
|
||||
|
||||
|
||||
There is a proxy file locking protocol described in FHS:
|
||||
http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES
|
||||
|
||||
But it has shortcommings (see below). Decisive obstacle for its usage are the
|
||||
possibility for stale locks and the lack of shared locks.
|
||||
|
||||
DDLP-B rather defines a "path prefix" which is advised to be
|
||||
/tmp/ddlpb-lock-
|
||||
This prefix will get appended "device specific suffixes" and then form the path
|
||||
of a "lockfile".
|
||||
Not the existence of a lockfile but its occupation by an fcntl(F_SETLK) will
|
||||
constitute a lock. Lockfiles may get prepared by the sysadmin in directories
|
||||
where normal users are not allowed to create new files. Their rw-permissions
|
||||
then act as additional access restriction to the device files.
|
||||
The use of fcntl(F_SETLK) will prevent any stale locks after the process ended.
|
||||
It will also allow to obtain shared locks as well as exclusive locks.
|
||||
|
||||
There are two classes of device specific suffixes:
|
||||
|
||||
- Device file path suffix. Absolute paths only. "/" gets replaced by "_-".
|
||||
Eventual "_-" in path gets replaced by "_-_-". The leading group of "_-"
|
||||
is always interpreted as a group of "/", though. E.g.:
|
||||
/dev/sr0 <-> "_-dev_-sr0"
|
||||
/mydevs/burner/nec <-> "_-mydevs_-burners_-nec"
|
||||
/dev/rare_-name <-> "_-dev_-rare_-_-name"
|
||||
///strange/dev/x <-> "_-_-_-strange_-dev_-x"
|
||||
|
||||
- st_rdev suffix. A hex representation of struct stat.st_rdev. Capital letters.
|
||||
The number of characters is pare with at most one leading 0. I.e. bytewise
|
||||
printf("%2.2X") beginning with the highest order byte that is not zero.
|
||||
E.g. : "0B01", "2200", "01000000000004001"
|
||||
|
||||
If a lockfile does not exist and cannot be created then this shall not keep
|
||||
a program from working on a device. But if a lockfile exists and if permissions
|
||||
or locking state do not allow to obtain a lock of the appropirate type, then
|
||||
this shall prevent any opening of device file in question and shall cause
|
||||
immediate close(2) of an already opened device file.
|
||||
|
||||
The vulnerable programs shall not start their operation before they locked a
|
||||
wide collection of drive representations.
|
||||
|
||||
Non-vulnerable programs shall take care to lock the suffix resulting from the
|
||||
path they will be using and the suffix from the st_rdev from that path.
|
||||
The latter is to be obtained by call stat(2).
|
||||
|
||||
Locks get upheld as long as their file descriptor is not closed or no other
|
||||
incident as described in man 2 fcntl releases the lock.
|
||||
|
||||
So with shared locks there are no imandatory further activities after they
|
||||
have been obtained.
|
||||
|
||||
In case of exclusive locks, the file has to have been opened for writing and
|
||||
must be truncated to 0 bytes length immediately after obtaining the lock.
|
||||
When releasing an exclusive lock it is a nice gesture to
|
||||
already do this truncation.
|
||||
Then a /var/lock/ compatible first line has to be written.
|
||||
E.g. by: printf("%10u\n",(unsigned) getpid()) yielding " 1230\n".
|
||||
|
||||
Any further lines are optional. They shall have the form Name=Value and must
|
||||
be printable cleartext. If such further lines exist, then the last one must
|
||||
have the name "endmark".
|
||||
Defined Names are:
|
||||
hostid =hostname of the machine where the process number of line 1 is valid
|
||||
start =start time of lock in seconds since 1970. E.g: 1177147634.592410
|
||||
program =self chosen name of the program which obtained the lock
|
||||
argv0 =argv[0] of that program

|

Any undefined name or a line without "=" shall be handled as comment.
|
||||
"=" in the value is allowed. Any line beginning with an "=" character is an
|
||||
extension of the previous value.
|
||||
|
||||
If programs encounter an exclusive lock, they are invited to read the content
|
||||
of the lockfile anyway. But they should be aware that the info might be in the
|
||||
progress of emerging. There is a race condition possible in the short time
|
||||
between obtaining the exclusive lock and erasing the file content.
|
||||
If it is not crucial to obtain most accurate info then one may take the newline
|
||||
of the first line as indicator of a valid process number and the "endmark"
|
||||
name as indicator that the preceding lines are valid.
|
||||
Very cautious readers should obtain the info twice with a decent waiting period
|
||||
inbetween. Only if both results are identical they should be considered valid.
|
||||
|
||||
|
||||
There is no implementation of DDLP-B yet.
|

|

|
||||
|
||||
----------------------------------------------------------------------------
|
||||
What are the Stumble Stones ?
|
||||
----------------------------------------------------------------------------
|
||||
|
||||
Any of the considered locking mechanisms has decisive shortcommings
|
||||
which keeps it from being the solution to all known legitimate use cases.
|
||||
|
||||
The attempt has failed to compose a waterproof locking mechanism from means of
|
||||
POSIX, FHS and from hardly documented Linux open(O_EXCL) on device files.
|
||||
The resulting mechanisms would need about 1000 lines of code and still do
|
||||
not close all gaps and cover the well motivated use cases.
|
||||
This attempt you see above: DDLP-A and DDLP-B.
|
||||
|
||||
|
||||
Summary of the reasons why the established locking mechanisms do not suffice:
|
||||
|
||||
None of the mechanisms can take care of the double device driver identity
|
||||
sr versus sg. To deduce the one device file from the other involves the need
|
||||
to open many other (possibly unrelated) device files with the risk to disturb
|
||||
them.
|
||||
This hard to solve problem is aggravated by the following facts.
|
||||
|
||||
Shortcommings of Linux specific open(O_EXCL) :
|
||||
|
||||
- O_EXCL | O_RDONLY does not succeed with /dev/sg*
|
||||
- O_EXCL cannot provide shared locks for programs which only want to lock
|
||||
against burn programs but not against their own peers.
|
||||
- O_EXCL keeps from obtaining information by harmless activities.
|
||||
- O_EXCL already has a meaning with devices which are mounted as filesystems.
|
||||
This priority meaning is more liberal than the one needed for CD/DV recording
|
||||
protection.
|
||||
|
||||
Shortcommings of POSIX fcntl(F_SETLK) :
|
||||
|
||||
- fcntl() demands an open file descriptor. open(2) might have side effects.
|
||||
- fcntl() locks can be released inadvertedly by submodules which just open and
|
||||
close the same file (inode ?) without refering to fcntl locks in any way.
|
||||
See man 2 fcntl "This is bad:".
|
||||
Stacking of software modules is a widely used design pattern. But fcntl()
|
||||
cannot cope with that.
|
||||
|
||||
Shortcommings of FHS /var/lock/ :
|
||||
|
||||
- Stale locks are possible.
|
||||
- It is necessary to create a file (using the _old_ meaning of O_EXCL flag ?)
|
||||
but /var/lock/ might not be available early during system start and it often
|
||||
has restrictive permission settings.
|
||||
- There is no way to indicate a difference between exclusive and shared locks.
|
||||
- The FHS prescription relies entirely on the basename of the device file path.

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.

Above discussion why crc_ccitt() and crc_11021() yield identical results
|
||||
can be changed from 16 bit to 32 bit by chosing h(a) and l(a) so that:
|
||||
r(a) = h(a) * X * X * X + l(a)
|
||||
h(a) corresponds to the highest byte of crc(A), whereas l(a) corresponds
|
||||
to the lower three bytes of crc(A).
|
||||
|
||||
This yields
|
||||
r(a * X + b)
|
||||
= 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 , 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 reduces 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.

/* Architectural aspects */
|

/*
|
||||
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 the main operating system dependent SCSI part of libburn. It implements
|
||||
the transport level aspects of SCSI control and command i/o.
|
||||
|
||||
Present implementation: FreeBSD CAM (untested)
|
||||
|
||||
|
||||
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 offers 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().

|

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: NetBSD 6, ioctl SCIOCCOMMAND
|
||||
>>> ??? for OpenBSD too ?
|
||||
|
||||
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 offers 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().
|
||||
|
||||
