Re: [Tracker] Tracker / Tomboy / Maemo

[Cornelius Hald <hald icandy de>]

Hello again,

I spend some time today trying to get my code running. Unfortunately
without success yet. I hope someone here can help me, because I just ran
out of ideas :(

Here is what I did so far:

* I wrote a indexer module with the filename tomboy-notes.c which
compiles into libtracker-module-tomboy-notes.so. It's mainly boiler
plate code with very simple *_get_text() and *_get_metadata()
implementations.

* The file tomboy-notes.c is in my own project, not in the tracker
source tree. So to make it compile I had to copy the tracker-module-*.h
headers to my project. Not sure if that matters. Everything seems to
compile fine.

* Wrote a module file (code is below) and put it here:
/usr/share/tracker/modules/tomboy-notes.module

* Created a metadata file (code is below) here:
/usr/share/tracker/services/note.metadata

* Added the following to:
/usr/share/tracker/services/default.service

[TomboyNotes]
DisplayName=Tomboy Notes
Description=Tomboy Notes
Parent=Files
UIVisible=true
Icon=x-office-document
ShowServiceFiles=true
HasMetadata=true
HasFullText=true
HasThumbs=false


When I'm running "tracker-services -s" I get:
[...]
TomboyNotes
[...]
That looks good to me :)

When I'm running "tracker-services -p" I get:
[...]
Note:ChangeDate
Note:CreateDate
Note:Tags
Note:Text
Note:Title
[...]
Which looks also good.

But if I'm running "tracker-search -s TomboyNotes Hello" I get:
Service not recognized, searching in other files...

Which doesn't look that good to me.


Next thing is the log files:
tracker-indexer.log always only shows the following two lines:

16 Jun 2009, 21:00:40: Tracker-Critical **: Could not initialize the HAL
context, no error, is hald running?
16 Jun 2009, 21:00:40: GVFS-RemoteVolumeMonitor-Warning **: remote
volume monitor with dbus name org.gtk.Private.HalVolumeMonitor is not
supported

The trackerd.log shows lots of things. Some of the more remarkable
things are:
[...]

Well, I know this is a lot of information at once, but I hope you can
somehow help me. To me it looks like the actual tomboy-indexer library
is never loaded. Somehow I suspect that I named something wrong and that
is not found because of that. Well, than again I'm really new to tracker
and it could be everything. Maybe I didn't understand something
fundamental at all?

So here would be my actual questions, after all this noise :)

* Why is my indexer not called?
* What is ScanTimeout and CacheTimeout and it which unit is it measured?
* Is it possible to add a new *.service file instead of extending the
default.service file?


The complete source code can be found here if needed:

Thank you very much :)
