commit 7af31c92d71e11790f7b202dd8665140923ca24d
Author: Sam Thursfield <sam afuera me uk>
Date: Sat May 2 16:46:28 2020 +0200
Port to Tracker 3
Mostly the port is straightforward, we connect to tracker-miner-fs
explicitly over D-Bus instead of the centralized tracker-store daemon
we connected to previously.
The search-engine-tracker test is now isolated from the user's real
Tracker index using the `tracker-sandbox` script provided by Tracker,
and it lets tracker-miner-fs index the test file rather than trying
to synthesize the expected database contents.
There are more changes in nautilus-tag-manager.c. Until now, starred
file information was stored in the tracker-miner-fs database. This has
some downsides, firstly the data is deleted if someone runs `tracker
reset --hard`, secondly it isn't possible to do this from inside a
Flatpak sandbox with Tracker 3.0. because the
This commit changes the NautilusTagManager to set up a private
database inside XDG_DATA_HOME/nautilus/tags. This stores the starred
file information. The database is managed with Tracker, which allows us
to continue using the rename-tracking that tracker-miner-fs provides.
The same limitations apply as before that only files in indexed
locations can be starred.
