|
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.
|
|
|
|
*
|
|
Only if the new API compliance is enabled by macro Cdrskin_new_api_tesT .
|
|
Not yet by default. In many aspects this is already superior, note well :
|
|
|
|
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.
