LLSD serialization for viewer metrics.
|
|
First, introduced a compact payload format that allows blocks of
metrics to be dropped from the viewer->collector payload compressing
1200 bytes of LLSD into about 300, give-or-take. Then converted
to using LLSD arrays in the payload to enumerate the regions
encountered. This simplifies much data handling from the viewer
all the way into the final formatter of the metrics on the grid.

representation transferring ownership, doing data aggregation
in a very pedantic way. That's just adding unneeded cost and
complication. Used the same objects to transport data as are
collecting it and everything got simpler, faster, easier to
read with fewer gotchas. Bit myself *again* doing the min/max/mean
merges but the unittests where there to pick me up again. Added
a per-region FPS metric while I was at it. This is much asked
for and there was a convenient place to sample the value.

In the viewer, the region's UUID is acquired very late and isn't generally
used as the canonical region identifier. The U64 region hash is a better
and more consistently used identifier so I'm moving over to using that as
the region key. Don't have a proper reserved invalid region hash which is
unfortunate, but then, so much is.

timestamps.
The min/max response time calculations needed to be sensitive to the response
counts to know if their was actual data. Failure to do so introduced a
gratuitous min/max test against zero values which tended to corrupt the
mins. Unit tests added to test for this condition. Finished conversion
of times to floating point seconds. Removed two logging events used to
debug the cross-thread messaging. Looks like a code completion point.

After discussions, renamed 'QAModeMetricsSubmetrics' to 'QAModeMetrics'
and confirmed that LLCachedControl<> is the way to go. Moved the
resulting flag out of LLViewerAssetStats (where it didn't belong)
and it lives in both LLAppViewer and LLTextureFetch where it does
belong.
|
|
Detect QAMode (and new QAModeMetricsSubmode) settings which
enable logging of metrics report locally and a faster cycle
time to reduce test waiting. Do this only in the main thread
and propagate the result via collector constructors (will
likely move that out and put it in llappviewer/lltexturefetch
which is more correct scope). Managed to deadlock myself with
a recursive mutex (sheesh).

Removed declared but undefined interfaces from LLTextureFetch family.
Had inserted the cross-thread command processor into some of
LLTextureFetchWorker's processing which was unnatural and
probably wrong. Moved it to LLTextureFetch which turned out to
be far, far more natural. Better documentation on the asLLSD()
format. Refined LLSD stats merger logic and enhanced unit
tests to verify same.
|
|
Code complete with the intelligence to merge counts, mins,
maxes and means with reasonable defences. Added QAMode
controls to the viewer so that we can QA this more quickly
by reducing the timing interval and sending the metrics
body to local logging as well as to the caps service.

Asset fetch requests wrapped to allow for measurements.
Asset fetch enqueues, dequeues and completion times recorded
to asset stats collector. Texture fetch operations (http
and udp) recorded to asset stats collector. Stats collector
time vallue switched from F32 to U64 which is the more common
type in the viewer. Cross-thread mechanism introduced to
communicate region changes and generate global statistics
messages. Facility to deliver metrics via Capabilities
sketched in but needs additional work. Documentation and
diagrams added.

Cleanup passes on the two threaded collectors with better comments
and more complete unit tests.
|
|
This reduces the number of symbols in the viewer binary by about 30%.
Also, fixed test errors revealed by inlining being enabled.

Mainly expand the categories to include protocol and location/temp
nature of texture asset.
|
|
Code-complete with unit tests and foundation for other collectors.
Interestingly, sim and viewer have two different ideas about
asset type enumeration (compatible, one's just longer). Both
are missing mesh though that's to be expected.

|
Stuff moved over and adapted from simulator code. Basic, simple
counters and min/max/mean accumulators.

As advertized, I have removed the short-term hack that I put in place
to make release note URLs work. I have now put in place a more general
and correct solution. The key observeration from Roxie is that SLE
SLurls should have the same hostname as the grid host. So now, URLs
like http://google.com/app are no longer categorized as a SLurl and
produce errors when you click on them.

Backing out this merge that I pushed (prematurely) to the wrong place.

In LLVOVolume, added a count of LLMediaDataClientObjectImpl objects referencing each LLVOVolume object. This allows LLVOVolume::markDead() to skip the relatively expensive calls to removeFromQueue() when the LLVOVolume is known to have no active references.
Refactored LLMediaDataClient and its two child classes so that only LLObjectMediaDataClient has the round-robin queue (LLObjectMediaNavigateClient doesn't need it), and cleaned up some of the virtual function hierarchy around queue processing.
In LLMediaDataClient, added tracking for requests that aren't currently in a queue (i.e. requests that are in flight or waiting for retries) so they can be found when their objects are marked dead.
LLMediaDataClient::Request now directly keeps track of the object ID and face associated with the request.
Removed the "markedSent" concept from requests. Requests that have been sent are no longer kept in a queue.
The Retry timer now references the Request object instead of the Responder.
Replaced LLMediaDataClient::findOrRemove() with separate template functions for find and remove.

Added tags to some media-related logging in LLVOVolume.
Made LLMediaDataClient::Responder do most of its work in tick() instead of its destructor.
Added a comment to llmediadataclient.cpp that explains the idea behind the two-queue system.
Made LLMediaDataClient::sortQueue() remove requests from the queue that hold references to dead items. This should make teleporting away solve many of the pathological queueing cases.
Updated llmediadataclient test cases to reflect the change in behavior in sortQueue().
Removed some unnecessary const-ness in LLMediaDataClient::enqueue, which caused it to have to use const_cast.
