*	minor: move some compression related var setup inside compression if/then switch	Justin Clark-Casey (justincc)	2012-03-09	1	-4/+3

*	Put big fat EXPERIMENTAL warning in xassetservice database plugin	Justin Clark-Casey (justincc)	2012-03-09	1	-0/+10
\| \| \| \| \|	This should not currently be used in any circumstances except for experimentation. Database tables used by this plugin can still change at any time with no migration path.
*	Switch to sha256 from sha1 in order to avoid future asset hash collisions.	Justin Clark-Casey (justincc)	2012-03-06	1	-7/+15
\| \| \| \| \| \| \|	Some successful collision attacks have been carried out on sha1 with speculation that more are possible. http://en.wikipedia.org/wiki/Cryptographic_hash_function#Cryptographic_hash_algorithms No successful attacks have been shown on sha256, which makes it less likely that anybody will be able to engineer an asset hash collision in the future. Tradeoff is more storage required for hashes, and more cpu to hash, though this is neglible compared to db operations and network access.
*	remove unnecessary hash local variable	Justin Clark-Casey (justincc)	2012-03-05	1	-2/+0

*	Make asset compression optional. Currently set to false and not ↵	Justin Clark-Casey (justincc)	2012-03-03	1	-16/+24

*	Implement basic gzip compression for xassetdata	Justin Clark-Casey (justincc)	2012-03-03	1	-10/+41
\| \| \| \| \| \|	Whether this is worthwhile is debatable since here we are not transmitting data over a network In addition, jpeg2000 (the biggest data hog) is already a compressed image format. May not remain.
*	If asset data already exists with the required hash then don't rewrite it	Justin Clark-Casey (justincc)	2012-03-03	1	-17/+59

*	Perform asset storage transactionally	Justin Clark-Casey (justincc)	2012-03-02	1	-57/+69

*	Make xassetservice execute one query to retrieve the asset, not two	Justin Clark-Casey (justincc)	2012-03-02	1	-28/+4

*	Make XAssetService a de-duplicating asset service.	Justin Clark-Casey (justincc)	2012-03-02	1	-0/+416
	This is an extremely crude implemenation which almost works by accident. Nevertheless it does work. It can be tested with the instructions at http://opensimulator.org/wiki/Feature_Proposals/Deduplicating_Asset_Service#Testing It does not interact at all with the existing asset service or any data stored there. This code is subject to change without notice and should not be used for anything other than gawking.
