Hi Unity developers,
I'm the current packager for Unity-for-Arch project in Arch Linux. I've been
having a problem for quite a while now, where the launchers would
disappear when
the repective package was upgraded. I wrote a simple c program with
inotify, and
found that the Arch's package manager deals with upgrades differently
from dpkg.
On Ubuntu, an upgrade operation is like this:
* Install /usr/share/applications/firefox.desktop.dpkg-new
* Move /usr/share/applications/firefox.desktop.dpkg-new
to /usr/share/applications/firefox.desktop
On Arch, an upgrade operation is like this:
* Remove old /usr/share/applications/firefox.desktop
* Install new /usr/share/applications/firefox.desktop
This explains why the launchers were disappearing. How can I patch Unity
to deal
with this situation?
I wrote a (quite ugly) patch: http://paste.ubuntu.com/1622682/
The patch will wait for the package manager to exit before doing
anything, but
that hangs the launcher until the upgrade process is finished. Does the
wait_for_pacman() call belong someone else? Or should I approach this
differently?
Thanks in advance!
