mQueuedCommands was unsigned, but can become shortly negative.
Unfortunately this means I had to remove the assert that
keeps track of possible errors, but I believe that already
has been proven that it works anyway.
The reason it can become negative is because its meaning is
"Number of added ADD (request) commands minus number of REMOVE (request)
commands". Hence, it is incremented when an ADD command is added to the
queue and decremented when that ADD command is removed from the queue.
However, it is first decremented when a REMOVE command is added to the
queue and then incremented again when that REMOVE command is removed
again from the queue. Such a remove command is current extremely rare:
it only happens when curl fails to time out - and the backup timeout of
the statemachine fires after 10 minutes of a curl request being idle.
That should normally only happen if a request never reached curl of
course, and is queued in the curl thread, waiting to be added to curl,
aka: -0-0-1,{...} for 10 minutes...
Now that, in turn should be impossible (since the "don't count long poll
connections) unless the Curl* Debug Setting variables are changed to
wrong values.. but ok, can only guess here.
Furthermore, users may now type in grid name, grid nick, or grid login uri into the box and it will resolve to an existing grid they've used before, or (for uris only) try to add the new grid with the data it provides.
Input will have trailing and leading spaces trimmed.
Thanks to Diva Canto for this brilliant request!
New class ToggleControl is used in place of the removed listeners.
Much cleaner code for the MiniMap chat rings.
Remove redundant debug setting: MiniMapChatRings.
-Thanks Liru for the advices.
This is necessary for opensim mega regions that can have up to 16 long
poll connections for a single service, while upping the maximum number
of connections per service just for that is clearly nonsense.
I also changed that long poll connections do not "use" the "Other"
capability type (which shows that the debug info in the HTTP debug
console for the Other capability type turns grey when it only has event
poll connections). As a result additional connections become available
for textures, mesh and the inventory (the other capability types) on
opensim, which has all types on the same service, because now Other
does no longer constantly reserves a full share of the available
connections. This makes the actual number of connections used for
textures and mesh a lot more like it is on Second Life.
