The change makes two principal implementation changes:
[1] It removes the hard coded set of possible asset server client
implementations, allowing any arbitrary implementation that has been
identified to the PluginLoader as an appropriate extension. The
extension point for asset server client extension
is /OpenSim/AssetServerClient. All of the old configuration rules have
been preserved, and any of the legacy configuration values will still
work as they did before, except the implementation is now loaded as a
plug-in, rather than as a hard-coded instantiation of a specific class.
The re-hashing of IAssetServer as an extension of IPlugin made upgrading
of the implementation classes a necessity.
Caveat: I have not been able to meaningfully test the crypto-grid
clients. I believe they should work correctly, but the refactoring
necessary to handle plug-in based initialization (vs constructor-based
initialisation) admits the possibility of a problem.
[2] The asset cache implementation, previously introduce as a hard-code
class instantiation is now implemented as an IPlugin. Once again the
previous (configurationless) behavior has been preserved. But now it is
possible for those interested in experimenting with cache technologies
to do so simply by introducing a new extension for the asset cache
extension point (/OpenSim/AssetCache).
I've tested all of the configuration settings, after applying the patch
to a newly extracted tree, and they seem to work OK.
* As such, only a request for a non cached asset, the response and failures show up now.
* I know lbsa71 only put these in not long ago, so if they are really still required, I think we should think whether we can move the default log4net level off 'Debug'
To use, see the appearance section in opensim.ini.example, set "persist = true", then add the correct connection string for your database.(see mysql-AvatarAppearance.sql in share folder for a example of the table mysql table structure).
This could possible be used in a very small grid, but would mean each region server would need to connect to the same mysql database.
But the work to move the code to one of the grid servers shouldn't be too much.
* PrimitiveBaseShape: The textures are now exposed as a 'TextureEntry Textures'; all serialization still using the 'byte[] TextureEntry' for backwards compatibility.
* Scene: Re-added AddTree, since the Tree type isn't gone from libsl, merely relocated.
* The AssetServerBase is now responsible for dequeueing, the server implementations merely recieves ProcessRequest( AssetRequest req )
* Catchall added around queue processing thread so thread won't abort on exceptions.
Note this has lead to a big flat project, but I think a lot of the files we most likely don't even use any longer. And others belong in other projects/namespaces anyway.
