tracker_get_hit_counts: assertion `query->words' failed

[Tormod Volden]

Binary package hint: tracker

When I start typing something in the Search field of the deskbar applet, these messages appear in .xsession-errors:

** (trackerd:19109): CRITICAL **: tracker_indexer_get_hits: assertion `query->words' failed

[Bryan (brywilharris)]

I am getting this error and tracker is not getting any hits. I can look at tracker-stats and the program is indexing: (see below) but even if I search for something it should find like "grub" nothing comes up.

I take that back it is indexing. I restarted the tracker daemon with the "trackerd -R" command. I do get this error message, but it seems to be working.

I had a similar error that caused the "Bug Buddy" to pop up and ask me to send my data to Gnome:

http://bugzilla.gnome.org/show_bug.cgi?id=489094

** (trackerd:5479): CRITICAL **: tracker_indexer_get_hits: assertion
`query->words' failed

But they market it as a duplicate of http://bugzilla.gnome.org/show_bug.cgi?id=474131

** (trackerd:6248): CRITICAL **: scan_directory: assertion
`tracker_is_directory (uri)' failed

and they noted that:

"it's from tracker returning a file that does not exist anymore. It's
fixed in 2.20.1"

so the fix is ready upstream...

[Tormod Volden (tormodvolden)]

Conrad, I think your crash was not caused by the "tracker_indexer_get_hits: assertion`query->words' failed" message. I get the message after typing one letter in the search box, and no crash. I would have preferred if you left my description as is, and rather filed a new bug which we could have duped or unduped.

What do they mean by "in 2.20.1"? My tracker is 0.6.3-0ubuntu3, and I already have some gnome 2.20.1 packages.

[Tormod Volden (tormodvolden)]

I usually get 10 repetitions of the message for each letter I type.

[Tormod Volden (tormodvolden)]

Ok, I think I understand the versions they were talking about: I have deskbar-applet 2.20.0-0ubuntu2 only.

[Conrad Knauer (atheoi)]

Did you want me to still file my bug description as a separate bug?

[Tormod Volden (tormodvolden)]

Well, I hope both issues are solved in deskbar-applet 2.20.1 :) But I think this is a tracker problem. I had a closer look with gdb:

When I type a letter, it get down as "search_string" to tracker_db_search_text():
        array = tracker_parse_text_into_array (search_string);
The returned array is empty*, so when "query" is built up with
        for (pstr = array; *pstr; pstr++) {
                tracker_add_query_word (query, *pstr, WordNormal);
query->words will be empty and calling tracker_indexer_get_hits(query) will complain.

*) Inside tracker_parse_text_into_array(), tracker_parse_text_to_string() with one letter just returns a space:
 tracker_parse_text_to_string("d",1,0) -> " "
It seems like strings of 1 or 2 characters are stripped away.

I can just tell what's happening, I don't know if this is intended behaviour.

[Jamie McCracken (jamiemcc-blueyonder)]

minimum search word length is 3 by default

[Tormod Volden (tormodvolden)]

So I guess is shouldn't check for hits before I have typed 3 letters then?

[Conrad Knauer (atheoi)]

Based on your filing of a separate Gnome bug, I'm going to split off my bug report into its own and revert the description.

[Conrad Knauer (atheoi)]

If its not the same bug, this one isn't confirmed...

[Conrad Knauer (atheoi)]

Mine is now Bug #156358 BTW...

[Daniel T Chen (crimsun)]

Is this symptom still reproducible in 8.10?

[Tormod Volden (tormodvolden)]

No, there's nothing in .xsession-errors now. BTW, the Deskbar applet is not in the panel by default any longer.

I'm on ubuntu intrepid and this bug appear when I make a research with one letter ! Obviously GUI is not able to display results and trackerd crashes because GUI has a short respond time window, but trackerd is still searching all case with this letter ( and use huge processor works ).

For example I make one research with "a" case ( same results with other letters )

$trackerd -f

And tracker still searching !

GUI ask "Did you mean" but proposal !

I'm waiting.... I'm waiting.... I'm waiting, but not proposal.

Trackerd have to stop proposal feature if submitted case are too short for avoid this bug !
