(Updated Sept. 8, 2016, 10:02 p.m.)


Status
------

This change has been marked as submitted.


Review request for KDE Frameworks and David Faure.


Changes
-------

Submitted with commit a03b0caa4ca1fbfc249bfc0c2730aac340bbf929 by Christoph Cullmann \
to branch master.


Repository: baloo


Description
-------

ATM, I think baloo is missing a lot of checks for "mdb has seen problems".

Easiest case: you have a corrupted index database (easy to reproduce: echo BLA >> \
index in the baloo .local/... directory)

=> start baloo_file => directly crashs

Fix: try to create db, honor success, cleanup, try to create again, if still broken \
=> exit


Diffs
-----

  src/file/main.cpp 9410635 

Diff: https://git.reviewboard.kde.org/r/128865/diff/


Testing
-------

Corrupted DB via

[cullmann@gekko baloo]$ pwd
/home/cullmann/.local/share/baloo
[cullmann@gekko baloo]$ echo skljdflksjdf >> index

=> started baloo_file

=> old version: will segfault for ever on each start
=> new version: works after cleanup


Thanks,

Christoph Cullmann
