2011-03-16s3-printing: fix memory leak in print_cups.cDavid Disseldorp1-16/+9
As found by valgrind, tmp_pcap_cache is not freed following printer list tdb update. Signed-off-by: Andreas Schneider <asn@samba.org> Autobuild-User: Andreas Schneider <asn@cryptomilk.org> Autobuild-Date: Wed Mar 16 16:37:58 CET 2011 on sn-devel-104
2011-03-16s3-printing: remove duplicate cups response processing codeDavid Disseldorp1-147/+94
There is currently a lot of duplicate code included for processing responses to CUPS_GET_PRINTERS and CUPS_GET_CLASSES requests. This change splits this code into a separate function. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-03-16s3-printing: use printcap IDL for IPCDavid Disseldorp1-131/+107
Use printcap IDL for marshalling and unmarshalling messages between cups child and parent smbd processes. This simplifies the IPC and ensures the parent is notified of cups errors encountered by the child. https://bugzilla.samba.org/show_bug.cgi?id=7994 Signed-off-by: Andreas Schneider <asn@samba.org>
2011-03-04s3-printing: fix cups pcap reload with no printersDavid Disseldorp1-12/+27
cups_async_callback() is called to receive new printcap data from a child process which requests the information from cupsd. Newly received printcap information is stored in a temporary printcap cache (tmp_pcap_cache). Once the child process closes the printcap IPC file descriptor, the system printcap cache is replaced with the newly populated tmp_pcap_cache, however this only occurs if tmp_pcap_cache is non null (has at least one printer). If the printcap cache is empty, which is the case when cups is not exporting any printers, the printcap cache is not replaced resulting in stale data. https://bugzilla.samba.org/show_bug.cgi?id=7915 Signed-off-by: Andreas Schneider <asn@samba.org>
2011-03-04s3-printing: remove unneeded local_pcap_copy globalDavid Disseldorp1-36/+18
The cups local_pcap_copy global served as a temporary buffer during asynchronous cups printcap cache updates, as well as indicating when the printcap cache had not yet been filled and printcap cache update should block. As smbd printcap reads are now triggered by the parent smbd following printcap cache update, the variable and blocking mechanism are no longer needed. Signed-off-by: Andreas Schneider <asn@samba.org>
2011-01-07s3-printing: remove old entries in pcap_cache_replaceDavid Disseldorp1-6/+5
Callers of pcap_cache_replace() assume the existing printcap cache is replaced by the new values provided. This is not currently the case, old entries should be removed.
2011-01-07s3-printing: reload shares after pcap cache fillDavid Disseldorp1-8/+32
Since commit eada8f8a, updates to the cups pcap cache are performed asynchronously - cups_cache_reload() forks a child process to request cups printer information and notify the parent smbd on completion. Currently printer shares are reloaded immediately following the call to cups_cache_reload(), this occurs prior to smbd receiving new cups pcap information from the child process. Such behaviour can result in stale print shares as outlined in bug 7836. This fix ensures print shares are only reloaded after new pcap data has been received.

2010-03-25Fix bug #7288 - SMB job IDs in CUPS job names wrong.Jeremy Allison1-1/+10
Based on a patch from Michael Karcher <samba@mkarcher.dialup.fu-berlin.de>. I think this is the correct fix. It causes cups_job_submit to use print_parse_jobid(), which I've moved into printing/lpq_parse.c (to allow the link to work). It turns out the old print_parse_jobid() was *broken*, in that the pjob filename was set as an absolute path - not relative to the sharename (due to it not going through the VFS calls). This meant that the original code doing a strncmp on the first part of the filename would always fail - it starts with a "/", not the relative pathname of PRINT_SPOOL_PREFIX ("smbprn."). This fix could fix some other mysterious printing bugs - probably the ones Guenther noticed where job control fails on non-cups backends. Guenther PLEASE CHECK ! Jeremy.
2010-03-24Fix bug #7269 - Job management commands don't work for CUPS queues.Michael Karcher1-1/+9
Samba needs to retrieve pjob->sysjob from the CUPS response (as is done in the iprint backend).

2009-05-27s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen1-2/+2
When we run out of file descriptors for some reason, every new connection forks a child that immediately panics causing smbd to coredump. This seems unnecessarily harsh; with this code change we now catch that error and merely log a message about it and exit without the core dump. Signed-off-by: Tim Prouty <tprouty@samba.org>

Unsupported character set. Cups 1.3.4 expects utf8 to be used in all messages to/from the server. We may be using a different character set so we need to use talloc utf8 push/pull functions in all communication. Needs more testing. Don't release until I've done a thorough test. I also have a version for 3.2.x. Jeremy.
