But memory, I beg to differ :). Running on massif a from-scratch indexing of this laptop's homedir, tracker-store peaks at 16MB and runs under half of that for 67/69 snapshots. tracker-miner-fs peaks at 13MB and sits on half of that afterwards. In short only tracker-extract is "expected" to misbehave memory-wise (due to third party libraries, bugs, leaks in those, ...). The other daemons are rather moderate in memory consumption, although maybe seen over the "I can do without this" prism, sure looks like a waste ;). Worth pointing out too, tracker-extract had for years a hard memory limit, so if anything asked too much memory, tracker-extract would crash and be eventually (re)started at some point. I ended up removing it because the many bogus retrace reports, the many "it didn't index this super-important file" complains and because some file/library combinations actually needed more memory than given (poppler, if you wonder). If a library leaks or allocates too much memory, it's a bug in the library and should be fixed there, or so I thought :). > > "I don't think we'll support running without tracker anytime > soon." > > I read: > > "I don't think we will have a usable GNOME3 on the Raspberry > Pi anytime soon." Tracker comes from the mobile world, it has been used several times there with success, and has a number of gsettings that allow it to accommodate to very different workloads (most of them sacrificing instantness for reduced resources). But Tracker is, by default, optimized for the desktop. It would be nice if Tracker worked better out of the box on those setups, however I'd rather put all my fish on the "fix file notification" pan, as that's IMHO the key to making Tracker a single size for all.
