Title:
Getting package versions via dpkg-query on startup is very expensive
Status in Canonical System Image:
Fix Released
Status in unity-scopes-shell package in Ubuntu:
Fix Released
Bug description:
The plugin executes dpkg-query on startup to get version numbers of 3
important packages (scopes-api, unity8, self). They are then passed to
Smart Scopes Server with every request. Using dpkg-query at this stage
seems to have big impact on startup time of the Dash (and phone).
Michael Vogt suggested a simple postinst/postrm script that is
executed for all 3 packages to put & update their versions via a flat
text file, e.g.
::::::::::::::
debian/postinst
::::::::::::::
#!/bin/sh
set -e
if [ "$1" = "configure" ]; then
dpkg-query -W -f'${Version}' $DPKG_MAINTSCRIPT_PACKAGE \
> /var/lib/unity-scopes-shell/$DPKG_MAINTSCRIPT_PACKAGE
fi::::::::::::::
debian/postrm
::::::::::::::
#!/bin/sh
set -e
rm -f /var/lib/unity-scopes-shell/$DPKG_MAINTSCRIPT_PACKAGE
