Bug#998318: cups-client: lpoptions ignores and deletes settings of printer instances in ~/.cups/lpoptions

[Martin Zimprich]

I've drawn the Debian source package in order to rebuilt binary packages 
for CUPS 2.3.3op2-3+deb11u1.


Findings:

- CUPS builds fine without applying any patch
- applying the patch cited above under 
https://github.com/OpenPrinting/cups/issues/282 
and jusr rebuilding 
CUPS results in some errors in the clean step. Maybe this is a general 
issue with the current debian source package
- drawing sources, applying patch (without previously compiling original 
sources) and building works fine
- the resulting binaries seem to resolve the problem when installing at 
least following binary packages on the system:

 - cups_2.3.3op2-3+deb11u1_amd64.deb
 - cups-bsd_2.3.3op2-3+deb11u1_amd64.deb
 - cups-client_2.3.3op2-3+deb11u1_amd64.deb
 - cups-common_2.3.3op2-3+deb11u1_all.deb
 - cups-core-drivers_2.3.3op2-3+deb11u1_amd64.deb
 - cups-daemon_2.3.3op2-3+deb11u1_amd64.deb
 - cups-server-common_2.3.3op2-3+deb11u1_all.deb
 - libcups2_2.3.3op2-3+deb11u1_amd64.deb
 - libcupsimage2_2.3.3op2-3+deb11u1_amd64.deb

I would be pleased if the above mentioned fix could be included in 
debian stable.

Upstream has responded at

  https://github.com/OpenPrinting/cups/issues/282

and asked

  Would you mind applying the patch and telling me whether 
  it helps with your issue?

Applying patches and rebuilding is not in my skill set. Can you help out
here, Martin? Thorsten?

Cheers,

Brian.

* any attempt to modify printer instance settings using "lpoptions -p
laserjet5si/konzept -o InputSlot=Upper" results in deletion of all
"Dest" lines previously present within lpoptions file and modification
of the single line that was considered to be affected

Not quite my observation. I cannot set up more than one instance. Adding
a second one witj lpoptions deletes the existing one. You show five
lines in your example. Was ~/.cups/lpoptions edited by hand?



For clarification:
The  ~/.cups/lpoptions file cited above has been extracted from a backup 
taken before upgrade towards debian bullseye (minus potential but in 
case present unintentional modifications while copy-pasting from the 
backup).
It is being rewirtten in the same way you reproduced above upon any 
attempt to issue an "lpoptions -p" command with the new CUPS installation.


Thanks for keeping tracks of this issue.

Regards,
Martin

That's not me, Martin, but we thank you for your comprehensive report.

Agreed.

It appears that an instance is inheriting options from the main queue.
This is not supposed to happen. An instance is also not shown in the
output of 'lpstat -a'.

Not quite my observation. I cannot set up more than one instance. Adding
a second one witj lpoptions deletes the existing one. You show five
lines in your example. Was ~/.cups/lpoptions edited by hand?

I spent little time on this. Partly because buster's Firefox did not
display instances for me and partly because I am wary of trusting an
app's dialog to do the right thing.

Debian 10 has CUPS 2.2.10. The following link describes very similar
observations to ours when CUPS 2.2.12 is used:

Bug#998318: cups-client: lpoptions ignores and deletes settings of printer instances in ~/.cups/lpoptions

[Martin Zimprich]

Package: cups-client
Version: 2.3.3op2-3+deb11u1
Severity: normal

Dear Maintainer,

after upgrade from to Debian buster to bullseye (cups-client 2.2.10-6 to 
2.3.3op2) the lopptions does not properly handle printer instances defined in 
~/.cups/lpoptions

Symptoms:
* "lpoptions -p laserjet5si/konzept -l" gives the same output as "lpoptions -p 
laserjet5si/manuell -l" (namely the default printer settings made in CUPS) 
while lpoptions file defines different settings for both of these instances 
(see example file below)
* any attempt to modify printer instance settings using "lpoptions -p 
laserjet5si/konzept -o InputSlot=Upper" results in deletion of all "Dest" lines 
previously present within lpoptions file and modification of the single line 
that was considered to be affected
* third party applications such as Okular (4:20.12.3-2) are not able to display 
or use any printer instance defined
* downgrade to cups-client 2.2.10 and according dependencies seems to bypass 
the problem and allows the very same third party applications to display and 
use printer instances again

-- example ~/.cups/lpoptions file in use:

Default bx310fn
Dest laserjet5si/blank_duplex Duplex=DuplexNoTumble InputSlot=LargeCapacity
Dest laserjet5si/konzept InputSlot=Upper 
Dest laserjet5si/manuell InputSlot=Manual
Dest P6021cdn InputSlot=MF1
