Currently print job spooling via smbd using printer share file IO in
3.6 and master is broken, as described in bug 8719.
When smbd takes responsibility for spooling a print job, the
spool-file path is generated and created in print_spool_open() without
a jobid component.
StartDocPrinter is then called to register the corresponding job with
the spoolss layer. The spoolss layer validates the spool-file's
existence.
When EndDocPrinter is called, the spool-file path is passed to
cups_job_submit() for printing. cups_job_submit() uses this path to
obtain the print jobid via print_parse_jobid(), which assumes a
smbprn.$JOBID.$TMP_HASH format. Where the spool-file path does not meet
this format requirement, job submission fails.
This patch set attempts to fix smbd print job spooling by removing the
reliance on the spool file name to obtain the jobid, instead storing
the value in a tdb. Feedback appreciated.
Cheers, David
