Summary0007639: [PATCH] Bring FSAssets closer to OpenSim conventions
DescriptionSummary of changes, i might have missed some but the main changes are...
 
* If no connection string found in assets config, fallback to using default
 database config
* Create database storage interface to allow other db connectors to be written at some point
* Add MySQL migrations file to create the initial db table
* Added new config option named "DaysBetweenAccessTimeUpdates" to reduce db load by only updating access times when fetching assets if the last access time was over the threshold. This idea was taken from XAssets service.
* Change log message headers to indicate FS assets is the source not just assets
Additional InformationI havnt tested on linux yet.

When other grid services require access to assets, they may create secondary instances of the service. Not currently a problem with master code, but is a possibility. I have a custom service that creates an instance to access texture assets and because both registered console commands and started the writing thread, things went wrong fast. When i ran the import command, a combination of the import process starting twice and two writer threads fighting over the contents of the spool directory caused a flood of file access and file not found exceptions.

The patch fixes this problem by only registering the commands and starting the writer thread for the first instance. The technique i used was borrowed from Diva when she ran into the same problem with multiple console commands in another service.

Thanks

Edit: another patch is attached to add the config options to robust.ini example files.

It should probably be documented that the spool and base directories must be on the same physical filesystem because atomic move operations from spool to final destination are used by the code.
