[Pkg-cups-devel] Bug#637978: cups: Please add a dpkg trigger to update PPDs on driver upgrades

[Didier Raboud]

Hi all, 

just a short mail summarizing the discussions we had on #ubuntu-devel 
regarding this proposal.

The current plan is:

1) externalize the current postinst code to an external program, based on the 
current cupsppdupdater code in pkg-printing-tools.
2) Have cups trigger on files under /usr/share/cups/ppd-updaters/
Those files, put there by the driver packages, will contain shell variable 
definitions: DRIVER_REGEXP and GENNICKNAME_REGEXP , which cups' postinst will 
use (when called as "triggered") to launch cupsppdupdater with the correct 
parameters.
3) Migrate all drivers to stop duplicating functionality in their postinsts 
and ship a /usr/share/cups/ppd-updaters/${package} file with the correct 
variables (+ versioned Breaks against cups).

Cheers,
