Version: 1.1.19rc4
CUPS.org User: pipitas

I can reproduce this at will....

Certain printfiles on hold in the spool directory cause
cupsd to fail starting. If I move the files away the startup

completes. If I move only one of the files back, it fails.

kde-bitshop:/usr/lib/cups/backend # /etc/init.d/cups start
cupsd: Child exited on signal 11!
cups: unable to start scheduler.

This is how far the scheduler logs its startup phase (LogLevel debug2
can be created on demand):

-rw------- 1 lp sys 583 May 10 15:32 /var/spool/cups/c02226

I moved all job (simple ASCII) and control files from the spool directory.
one after the other and re-started again. The signal 11 always occured after
loading job attributes for job 2163. Only when everything above 2226 was
away, did the scheduler start up completely.

So -- what's up with these files' job attributes to cause such a nasty
error? The files are simple ASCII, and the c-files are revealing nothing
special if looked at with the strings utiliy.... (Attached to STR)

Cheers,
Kurt [ BTW, is there a utility to look at the content of the c-files?
Appart from KDEPrint's "IPP report" feature, I mean? ]

More info:

You'll notice that I am using a few additional backends
and filters. These are mainly shell scripts I play with.
They haven't been changed for a few days, and they did
never cause problems to the scheduler's startup.

What I changed on this system today:

  • added the printers hp8550clj and hp4550
  • printed a few jobs to printers
  • printed a few jobs "on hold" (amongs them the weird ones)
  • upgraded to 1.1.19rc4 (from rc2)
  • tested web interface authentication
  • found problems described in STR job management via web interface not working (authentication problems) #81
  • changed cups.conf from "Satisfy Any" to "Satisfy All"
  • restarted cupsd and encoutered problem.

The testipp program in the cups subdirectory can be used to list the attributes in the job control file.

The control file for job 2226 has a job-state attribute of type nameWithoutLanguage (it should be an enum...) This is likely the cause of the problem... I'll update the code to check for this and log this error if found, however we need to determine how this happened...

The attached patch should correct this problem and has been commited to CVS for rc5.
