Telehub commits! They will eat your babies and corrupt your database while
they munch. DO NOT use anything from the first Telehub commit to this one.
FIRST GOOD COMMIT is the one FOLLOWING this one. You have been warned.
This is damage control es EstateSettings is not the place this can be put.
EstateSettings is nt unique to a region and therefore would introduce
a hard limit of one telehub per estate, completely shutting off the
option of having SL style telehubs, e.g. one per region. Whole
estate teleport routing can still be implemented id desiresd, this
way all options are open while the other way most options get closed
off.
Telehub settings now persist to the database and are saved across sim restarts. So-far this only works on MySQL. this is a work in progress, teleport routing is not yet implemented.
Using the RemoteAdmin API to close then recreate a region would fail if the estate name had not changed. If the estate name /was/ changed then the existing estate would be renamed rather than a new one being created. The problem really arose from a lack of distinction in the data storage layer between creating new estates and loading existing ones.
Leaving them at UUID.Zero meant that when a viewer 2 logged into a region that had been freshly created, it received UUID.Zero for these textures, and hence display the land as plain white.
On a simulator restart, the problem would go away since when the database adapators loaded the new region settings, RegionSettings itself has code to use default textures instead of UUID.Zero.
This commit resolves the problem by saving the default texture UUIDs instead of Zero.
However, we currently have to do this in a roundabout way by resaving once the RegionSettings have been created by the database for the first time. This needless complexity should be addressed.
This change will also have the effect of replacing any existing UUID.Zero terrain textures with the default ones.
However, this shouldn't have any effect since the UUID.Zeros were already being replaced in memory with those same UUIDs.
Using MyISAM proves vastly faster for persisting scene objects.
For instance, a scene object that took 9 seconds to persist before now takes 1. This also improves the experience of loading large OARs.
We don't use any of the transactional features of InnoDB.
The only thing that may have an impact is that InnoDB does row locking on inserts while MyISAM does table locking.
However, field reports say there is no noticeable difference.
Revert "Changed Friends table to have 165-sized varchars on PrincipalID and FriendID. The reason for this number is the following: there is a combined key of these 2 fields; apparently MySql can't handle keys larger than 1000 bytes; when the table is created with utf8 encoding, this combined key is bigger than 1000 bytes, and the migration fails. WARNING: this is not a new migration! People who have gone through this migration and failed should update the sizes of these fields manually."
This reverts commit 3fa54a156a.
