Review request for Akonadi and Daniel Vrátil.


Repository: akonadi


Description
-------

It happened to me that I started kmail but could not see any mail folder.
Searching I found that although all akonadi processes were running, the mysqld process was not,
so it seems for whatever reason mysqld crashed (using a privately started mysqld from akonadiserver).

This patch checks if the mysqld stops unexpectedly when it was started from akonadiserver and tells the latter to quit when a stopped mysqld was discovered.
Also in this case the local socket file is removed so that a restart can work without problem.


Diffs
-----

  src/server/storage/dbconfigmysql.h 27841e8 
  src/server/storage/dbconfigmysql.cpp 0962ccb 

Diff: https://git.reviewboard.kde.org/r/129264/diff/


Testing
-------

Started akonadi via akonadictl and also implicitely via kmail, then killed (-4, -15) mysqld.
Restarted via akonadictl or kmail


Thanks,

Martin Koller
