Re: [Tracker] tracker index interruption

[Adrien Bustany <abustany gnome org>]

Tracker journals transactions a bit the same way a filesystem does.
When
it starts and sees it didn't shutdown cleanly, it will replay the
journal
to ensure DB consistency.

About invalid files, a file is considered valid as long as its metadata
are valid. So if you mp3 file has valid ID3 tags but is malformed, the
extractor won't notice.

Cheers
