With tracker-control -s.

Thanks, learning Python and dbus on the fly, I was able to write
(well, really copy and paste) a simple tracker-miner-fs replacement
which can be activated and called from a python interactive shell.
This is the tracker-miner-fs replacement:
---8<---
#!/usr/bin/env python
import gobject
import dbus
import dbus.service
import dbus.mainloop.glib

class ExampleObject(dbus.service.Object):
    @dbus.service.method("org.freedesktop.Tracker1.Miner.Files",
                          in_signature='', out_signature='s')
    def Ping(self):
        return str("Hi. I am Alive")

if __name__ == '__main__':
    dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
    session_bus = dbus.SessionBus()
    name = dbus.service.BusName("org.freedesktop.Tracker1.Miner.Files",
session_bus)
    name2 = dbus.service.BusName("org.freedesktop.Tracker1.Miner.Applications",
session_bus)
    object = ExampleObject(session_bus, '/ExampleObject')

    mainloop = gobject.MainLoop()
    mainloop.run()
---8<---

I can interact with this just fine from a Python shell:

root solaris:~# env | egrep 'TRACKER|DBUS|XDG'
TRACKER_EXTRACTOR_RULES_DIR=/opt/tracker/share/tracker/extract-rules
TRACKER_DB_ONTOLOGIES_DIR=/opt/tracker/share/tracker/ontologies
DBUS_SESSION_BUS_ADDRESS=unix:path=/tmp/spotlight.ipc
XDG_DATA_DIRS=/opt/tracker/share/:/usr/share/
TRACKER_LANGUAGE_STOPWORDS_DIR=/opt/tracker/share/tracker/languages

root solaris:~# python
Python 2.6.8 (unknown, Aug 30 2012, 01:56:38) [C] on sunos5

The Python examples from freedesktop work just fine too... :/

Would it help running tracker-miner-fs from gdb?

Thanks!
