Re: [Tracker] [Announce] Tracker 0.5.1

[Mark Florian <markrian gmail com>]

Well done on the release!

I downloaded and built the tarball on Ubuntu edgy, using the included
debian directory without any changes (except 'dch -i'ing to make the
package with the right version number), and then of course installed the
new libtrackerclient0, tracker, tracker-gnome-search-tool, tracker-utils
debs.

I removed the old ~/.Tracker directory and set the new tracker indexing,
with the --turbo switch. After that was all done, I ran a few test
searches, and unfortunately, there still seem to be problems. To be
sure, I've since rebooted, re-removed ~/.Tracker and set trackerd to
index everything again, but without --turbo. Same story.

Firstly, I have a (text) file called "Jesus May Ball photos" with
various words inside. I ran a search for eaden (it's a name inside in
file) and this returns no results. I then did a 'cp "Desktop/Jesus May
Ball photos" Desktop/place', and watched ~/.Tracker/tracker.log. The
result was this:

07 Nov 2006, 12:33:02:221 - File /home/markrian/Desktop/place has
finished changing
07 Nov 2006, 12:33:02:227 - saving basic metadata for *new*
file /home/markrian/Desktop/place with mime unknown and service type 8
07 Nov 2006, 12:33:07:717 - Total entities index : 2567
07 Nov 2006, 12:33:07:717 - Please wait while remaining data is flushed
to the inverted word index. This may take some time...
07 Nov 2006, 12:33:07:719 - flushing data (3 words left) - please wait
07 Nov 2006, 12:33:07:720 - flushing data (2 words left) - please wait
07 Nov 2006, 12:33:07:721 - flushing data (1 words left) - please wait
07 Nov 2006, 12:33:07:762 - flushing data (0 words left) - please wait
07 Nov 2006, 12:33:07:762 - All data has been flushed - waiting for new
file events...

It seems that the mime type is unknown. If I do the same operation but
append a .txt to the file name, the following happens:

07 Nov 2006, 12:53:32:504 - File /home/markrian/Desktop/place.txt has
finished changing
07 Nov 2006, 12:53:32:508 - saving basic metadata for *new*
file /home/markrian/Desktop/place.txt with mime text/plain and service
type 6
07 Nov 2006, 12:53:32:512 - Extracting Metadata for *new*
file /home/markrian/Desktop/place.txt with mime text/plain and service
type 6
07 Nov 2006, 12:53:37:906 - Total entities index : 2576
07 Nov 2006, 12:53:37:906 - Please wait while remaining data is flushed
to the inverted word index. This may take some time...
07 Nov 2006, 12:53:37:912 - flushing data (17 words left) - please wait
[...etc...]
07 Nov 2006, 12:53:37:920 - flushing data (0 words left) - please wait
07 Nov 2006, 12:53:37:920 - All data has been flushed - waiting for new
file events...

And searches for eaden return the result of places.txt, but nothing
else.

If I search for 'jesus ball' then I get the result "Desktop/Jesus May
Ball photos" as expected.

The second problem is that I have a file called
bills_Maids_Causeway.ods. If I run a search for "bills maids causeway"
no results are returned. If I search for "bills_maids_causeway" then I
get that one result. The same effect can be seen with files
named-with-dashes-like-this.txt.

The third issue involves a test file I created, called 'whisper'. The
file, which I created in gedit, contains only the line:

I hear the sound of ticking clocks

Tracker's log picked it up, and registered the file with the correct
mimetype, text/plain. When I run a search for "ticking here", the file
whisper appears in the results. Is this expected behaviour? I would have
thought that search implied ticking AND here, not ticking OR here.

The fourth and final issue involves the other test file I created,
own_way.txt, containing the line:

To the end of the last page.

Searching for 'last' returns no results, and the log contains the
following interesting entries for this:

07 Nov 2006, 13:09:34:256 - Executing search with params Files, last
07 Nov 2006, 13:09:34:257 - tracker_indexer_get_hits: assertion
`(indexer && words && words[0] && (limit > 0))' failed
07 Nov 2006, 13:09:34:257 - search returned no results

I hope this information helps. If anyone would like more details/tests,
just say. Again, well done to all involved with this release! Tracker is
*totally* awesome.
