A cdrecord compatible command line interface for libburn.
This project is neither directed against original cdrecord nor does it exploit
any source code of said program. It rather tries to be an alternative method
to burn CD which is not based on the same code as cdrecord.
See also : http://scdbackup.sourceforge.net/cdrskin_eng.html
Interested users of cdrecord are encouraged to contribute further option
implementations as they need them. Contributions will get published under GPL
but it is essential that the authors allow a future release under LGPL and/or
BSD license.
There is a script test/cdrecord_spy.sh which may be installed between
the cdrecord command and real cdrecord in order to learn about the options
used by your favorite cdrecord frontend. Edit said script and install it
according to the instructions given inside.
The implementation of an option would probably consist of
- necessary structure members for structs CdrpreskiN and/or CdrskiN
- code in Cdrpreskin_setup() and Cdrskin_setup() which converts
argv[i] into CdrpreskiN/CdrskiN members (or into direct actions)
- removal of option from ignore list "ignored_partial_options" resp.
"ignored_full_options" in Cdrskin_setup()
- functions which implement the option's run time functionality
- eventually calls of those functions in Cdrskin_run()
- changes to be made within Cdrskin_burn() or Cdrskin_blank() or other
existing methods
See option blank= for an example.
------------------------------------------------------------------------------
About compliance with *strong urge* of API towards burn_drive_scan_and_grab()
For a more comprehensive example of the advised way to behave with libburn
see test/libburner.c .
cdrskin was the initiator of the whitelist functionality within libburn.
Now it has problems to obviously comply with the new API best practice
presciptions literally. Therefore this explanation:
On start it restricts the library to a single drive if it already knows the
persistent address by option dev= . This is done with a combination of
burn_drive_add_whitelist() and burn_drive_scan(). Not compliant to the
literal strong urge but in fact exactly fulfilling the reason for that
urge in the API: any scanned drive might be opened exclusively after
burn_drive_scan(). It is kernel dependent wether this behavior is on, off
or switchable. The sysdamin will want it on - but only for one drive.
So with dev=... cdrskin complies to the spirit of the strong urge.
Without dev=... it has to leave out the whitelist in order to enable bus
scanning and implicit drive address 0. A tradition of 9 months shall not
be broken. So burns without dev= will stay possible - but harmless only
on single drive systems.
Burns without dev= resp. with dev=number are harmless on multi-drive systems.
This is because Cdrskin_grab_drive() either drops the unwanted drives or
it enforces a restart of the library with the desired drive's persistent
address. This restart then really uses the strongly urged function
burn_drive_scan_and_grab().
Thus, cdrskin complies with the new spirit of API by closing down libburn
or by dropping unused drives as soon as the persistent drive address is
known and the drive is to be used with a long running operation. To my
knowlege all long running operations in cdrskin need a grabbed drive.
This spaghetti approach seems necessary to keep small the impact of new API
urge on cdrskin's stability. cdrskin suffers from having donated the body
parts which have been transplanted to libburn in order to create
burn_drive_scan_and_grab() . The desired sysadmin friendlyness was already
achieved by most cdrskin runs. The remaining problem situations should now
be defused by releasing any short time grabbed flocks of drives during the
restart of libburn.

This program is currently copyright Thomas Schmitt only.
The copyrights of several components of libburn.pykix.org are willfully tangled
at toplevel to form an irrevocable commitment to true open source spirit.
We have chosen the GPL for legal compatibility and clearly express that it
shall not hamper the use of our software by non-GPL applications which show
otherwise the due respect to the open source community.
See toplevel README and cdrskin/README for that commitment.
For a short time, this place showed a promise to release a BSD license on
mere request. I have to retract that promise now, and replace it by the
promise to make above commitment reality in a way that any BSD conformant
usage in due open source spirit will be made possible somehow and in the
particular special case. I will not raise public protest if you spawn yourself
a BSD license from an (outdated) cdrskin.c which still bears that old promise.
Note that this extended commitment is valid only for cdrskin.[ch],
cdrfifo.[ch] and cleanup.[ch], but not for libburn.pykix.org as a whole.
cdrskin is originally inspired by libburn-0.2/test/burniso.c :
(c) Derek Foreman <derek@signalmarketing.com> and Ben Jansens <xor@orodu.net>
