This patch adds an additional handler to the existing BaseHttpServer.
It does not affect any of the existing behaviors except insofar as the
new handler may be selected.
It is selected first because its Agent-oriented nature means that it
should not be pre-empted. The new handler type is defined by IHttpAgentHandler
in Framework/Servers and has two interface methods: Match and Handle.
The Match function returns a boolean result based upon examination of
information presented in the User-Agent header.
The Handle function expects to get the request and response instances
associated with the flow. The handler is responsible for ALL activity
associated with the request except in the event of an unhandled exception,
in which case the HandleAgentRequest routine will generate a 500 status
message and close the stream.
There are two immediateley apparent (and VERY easy to implement)
improvements that could be made:
1. The Match call could be allowed to operate over the entire
request context., rather than just agent identity.
2. The Handler could return a boolean indication of whether or not
the request was actually handled, and if not, the remaining handler
mechanism could take a shot at it. This would eliminate issues
arising from pre-empted streams.
enhancing IStreamHandler and IStreamedHandler interfaces so that OSHttp{Request,Response} get passed in,
allowing RestHandlers to set response status code, redirections, etc.
* If the status cannot be retrieved, then the region startup will terminate.
* The aim of this is for earlier detection of situations where the region can send messages out but cannot accept incoming requests (often due to firewall issues)
* This is currently an extremely simplistic check which completely trusts whatever http uri is given by the region
* This contact may be problematic, though since the user service needs to be able to contact the region http uri, it doesn't seem unreasonable for the grid to have to be able to do so too at this stage
* This change will require a prebuild
This patch makes the "Show in Search" checkbox on the viewer work. Additionally, I also discovered that show-in-search objects use the JointWheel flag, so this patch currently uses that flag. LibSL needs to add a flag to enum LLObject.ObjectFlags, "IncludeSearch = 32768" so we aren't using a legacy flag.
Additionally this patch also contains a small fix to BaseHTTPServer that lets the response content-type to be something other than text/html. For some reason this didn't get submitted with the DataSnapshot merge.
* Should work in multi-region standalone and grid modes
* This should also solve other non-home region caps issues (map requests, RC client inventory requests, etc)
* We now pass CAPS information on to the destination region on region crossing, and set up a CAPS object when an agent becomes a master
* Current limitation is that this will only work if your http_listener_port is 9000
* This is a very early code cut (lots of bad practice, hard coding and inefficiency). However, I wanted to get this out there for feedback and my own sanity. Next few patches will clean up the mess.
* This will make it more obvious if one accidentally starts one's region server in standalone rather than grid mode but then tries to login to a grid (as I am wont to do)
* We are now sending back a fault code (-32601) if no xmlrpc method is found rather than an ordinary message
* Cleaned up copyright notices in AssemblyInfo.cs's
* Added Copyright headers to a bunch of files missing them
* Replaced several common string instances with a static constant to prevent reallocation of the same strings thousands of times. "" -> String.Empty is the first such candidate.
* Don't forget, you need -loginuri *and* -loginpage
* Ex: -loginpage http://10.1.1.2:8002/?method=login -loginuri http://10.1.1.2:8002/
* The ?method=login is important, don't forget to add it
* If you customize your http_loginform.html file, be sure to keep the form post address as is.
* Added the web_login_key to the users table
* Added happy configurable http error message pages
* This update is large enough to have 'awe' value.. so backup your users or weep.
* Not tested on MSSQL, even though I added code to update the tables!
* I'm keeping it deactivated until some issues are resolved.
* I'm patching it in deactivated so the patch doesn't get outdated
* I've deactivated it by commenting out the handler for the application/xml+llsd content type.
* While I've tested this as much as possible on my setup and found the deactivated code doesn't cause any problems, consider this update experimental (event though it's deactivated)
* Added SSL Option to User Server to allow logins to be done via SSL.
* Added sane handling for when Remote Admin Plugin configuration is not found
* Added some performance boosts to an area of libTerrain which was highlighted in profiling.
* Sqlite Storage Engine now supports terrain -- however be aware that every terrain revision stored will at 512KB to your database file. At the moment it is storing every revision from the first.
* Fixed an issue where by noverbose mode would display lots of useless junk. Noverbose mode is now quite usable.
* Fixed a whole bunch of console message issues such as naming and categorisation
* Removed legacy REST handling
* Created two custom IStreamHandlers for asset up/download
* Removed quite a lot of double and triple encodings, trying to work towards binary only and direct write into storage.
* Introduced BaseStreamHandler with GetParam() and some other goodies
* Implemented RestStreamHandler
* Some caps functions now use it
* Moved out RestMethodEntry from httpserver
* The IStreamHandler interface now reports required method and Content-Type
