A tool to synchronize objects:
Objects derived from AISyncClient can signal that they are
'ready' or 'not ready' for up to 4 events (using a bitmask)
at a time. Clients that signal to be ready for anything
at roughly the same time as other clients, and which return
the same 'hash' (a virtual function returning a 64bit value)
will be grouped together and receive events (by means of
virtual functions being called) to notify them of all clients
being ready or not for one of the events (syncevent1).
The other three events can be polled.
The memory usage is low (one pointer per client that points
to its AISyncServer object), servers are released to a cache
after about 100 ms (unless there is actual need for synchronization),
so there aren't much of those either.
The CPU usage is extremely low: all events are handled in
parallel in a 32 bit value (6 bits per event to count the
number of registered clients and the number of ready clients
for each event, and the remaining 8 bits to count the
number of reference pointers (which should only be a constant
higher, so that is overkill). To signal to a server that
a client has become ready or not is mostly a function call,
which then takes 1 clock cycle or so before returning.
Registration of a client is slightly more expensive as it
requires a pointer to be added to the end of a std::list.
This tool could easily be used as part of the graphics engine
(not that I intend to do that :p).
There was a bug that when people turned off sending viewer effects,
they'd also turn off sending LookAt, while there is a seperate
checkbox to turn THAT off, while still seeing their own avatar
happily look around, breaking shared experience (most notably, most
people will be complete oblivious of the fact that they look like
zombies to others and that their friends do not see the same thing
on their screen).
This patch fixes this: both parties now see the same thing. Lookat
and PointAt are only turned off by their respective checkboxes,
and no longer silently influenced by turning off other viewer
effects.
For these standard motions, the viewer likes to very frequently
flood-call startMotion/stopMotion sometimes, which at the very
least needs a LLUUID lookup in a std::map. In particular, this
is done for two of them for every avatar in the sim every frame.
This code makes it possible to test if that makes sense by
merely doing a bit test.
Conflicts:
indra/llcharacter/llkeyframemotion.h
These changes were the result of my Motion leak audit.
However, there is a serious problem with LLKeyframeMotionParam
in that it stores plain pointers to objects that can and will be deleted
by other objects. Its the classicial LL example of coding
non-Object-Oriented badly maintainable and instable code.
I cannot make sure this won't go wrong for the simple fact
that LLKeyframeMotionParam is not used at ALL in our code.
Hence, the next commit will rather delete this file.
This commit is merely to have a record of this finding.
Fixed issue with fullbright and glow occlusion.
RenderTransparentWater toggling should work more gracefully.
Fixed some bugs in general drawpool classification for faces. Bump pool was superceding more than it should have.
Adds name list specific name settings, Removes boolean for having lists of speakers with legacy names in favor of having a more flexible setting for them
Have a look at the combo boxes on Adv. Chat->Chat UI to customize these new settings.
There is now a fourth option for name display: LegaCy Name (D is play Name)
