various fixes to lltrace
start() on started recording no longer resets
fixed various instances of unit forgetfullness in lltrace
recording split now has gapless timing
scene monitor now guarantees min sample time
renamed a bunch of stats
added names to debug thread view on windows
removed LLThreadLocalSingleton
collapsed all thread recorder classes to single type, LLTrace::ThreadRecorder
moved fasttimer stack head to llthreadlocalsingletonpointer via ThreadRecorder
fixed some lltrace logic errors
more consistent syncing of timestamps of sample values in recording stack
selection of primary buffers was completely incorrect
assignment of recordings got wrong play state due to implicit
operator = defined in base class
fixed asset stats only working up to the first send
removed implicit flushes on reads from recorders for better performance
made sure stack timers were updated on recorder deactivate
faster rendering and better ui for fast timer view
removed unnecessary templates from accumulator types...now always
track data in double precision floating point, using templated accessors to
convert to and from arbitrary types
fixed multithreading lltrace causing values to be interpolated towards 0
added Radians unit
improved sceneloadmonitor restart heuristic to use accumulated camera motion
reverted SlaveThreadRecorder update gating
moved processTimes() outside of Recording, so it is called only once per frame
refined sample merge logic so that multi-threaded samples do not stomp on linear history
of a stat
fixed LLTrace::ExtendablePeriodicRecording::extend() to include *all* frame extensions
gated SlaveThreadRecorder pushing to master based on master update rate
reverted changes to LLThreadLocalSingletonPointer to not use offset-from-default trick
fixed copy construction behavior of Recordings to not zero out data
split measurement into event and sample, with sample representing
a continuous function
removed extra dereference for copy on write pointer
moved copyonwrite mechanism to RecordingBuffers from individual buffer
fixed logic that was leaving scene unfrozen when camera moved during metrics gathering
fix for unit test failures...cleanup apr without destroying
pools, allowing LLProxy to clean itself up as a singleton (and
avoiding spurious dependencies associated with manually destorying
singletons that rely on apr pools)
made fast timer stack thread local
added LLThreadLocalSingleton
made LLThreadLocalPointer obey pointer rules for const
added LLThreadLocalSingletonPointer for fast thread local pointers
improvements on lifetime of lltrace core data structures
tweaks to thread local pointer handling so that static constructors/destructors
can safely call functions that use lltrace
cleaning up build
moved most includes of windows.h to llwin32headers.h to disable min/max macros, etc
streamlined Time class and consolidated functionality in BlockTimer class
llfasttimer is no longer included via llstring.h, so had to add it manually in several places
fixed trace data gathering and routing from background thread
simplified slave->master thread communication (eliminated redundant recording and proxy object)
improved performance of fast timer data gathering (slow iterators)
default to double precision now
fixed unit conversion logic for LLUnit
renamed LLTrace::Rate to LLTrace::Count and got rid of the old count as it was confusing
some const correctness changes
cleaned up accumulator merging logic
introduced frame recording to LLTrace directly instead of going through LLViewerStats
moved consumer code over to frame recording instead of whatever the current active recording was
moved threadrecorder classes into separate file
added Count trace type, which tracks value increases and decreases and can report churn
as well as overall growth rate
