removed complicated and unnecessary fast timer gapless handoff logic (it should be gapless anyway)
improved MemTrackable API, better separation of shadow and footprint
added memory usage stats to floater_stats.xml
|
|
|
|
continued conversion to units system
made units perform type promotion correctly and preserve type in arithmetic
e.g. can now do LLVector3 in units
added typedefs for remaining common unit types, including implicits
|
|
|
|
added convenience types for units F32Seconds, etc.
|
|
replace llinfos, lldebugs, etc with new LL_INFOS(), LL_DEBUGS(), etc.
|
|
added a Mesh status line to the texture fetch console. Mesh is
often in competition with textures and so the mesh information
seems appropriate there. Do get a nice feel for progress and
you definitely see when the throttles kick in.

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 LLTrace unit typedefs
|
|
|
|
changed Units macros and argument order to make it more clear
optimized units for integer types
fixed merging of periodicrecordings...should eliminate duplicate entries in sceneloadmonitor history
|
|
|
|
fixed mem stat tracking...now properly tracks memory footprint with floating point
precision
cleaned up macros for unit declaration
renamed units to SI standard for 1024 multiples (kibibytes, etc)
fixed units output for scene monitor dump

Most of the merge was clean, a couple conflicts.
Brought over a couple patches manually for llpolymesh.

fixes to merge

Finished making LLUnit implicitly convertible to/from scalar integer values
cleaned up test code
|
|
started conversion of llviewerassetstats
removed old, dead LLViewerStats code
made units tracing require units declaration
clean up of units handling
|
|
put template parameter back in LLUnit units
added free function operators for mathematical manipulation of unit values
converted texture memory tracking to units
|

This was yet another refresh from v-d because of significant changes
to lltexturefetch that would not have been resolvable by casual
application of any merge tool. There are still a few questions
outstanding but this is the initial, optimistic merge.

Big delta was converting the new texture debugger support code
to the new library. Viewer manifest should probably get an eyeball
before release.

log on exit.
With much trial-and-error, cleaned up the banner on the texture console and made everything
mostly fit. Added global cache read, cache write and resource wait count events to the
console display to show if cache is working. On clean exit, emit a log line to report
stats to log file (intended for automated tests, maybe):
LLTextureFetch::endThread: CacheReads: 2618, CacheWrites: 117, ResWaits: 0, TotalHTTPReq: 117

LLProxy support, HttpOptions starting to work, HTTP resource waiting fixed.
Non-LLThread-based threads need to do some registration or LLMutex locks taken out in these
threads will not work as expected (SH-3154). We'll get a better solution later, this fixes
some things for now. Tracing of operations now supported. Global and per-request (via
HttpOptions) tracing levels of [0..3]. The 2 and 3 levels use libcurl's VERBOSE mode
combined with CURLOPT_DEBUGFUNCTION to stream high levels of detail into the log. *Very*
laggy but useful. Simple GET request supported (no Range: header). Really just a
degenrate case of a ranged get but supplied an API anyway. Global option to use the
LLProxy interface to setup CURL handles for either socks5 or http proxy usage. This
isn't really the most encapsulated way to do this but a better solution will have to
come later. The wantHeaders and tracing options are now supported in HttpOptions giving
per-request controls. Big refactoring of the HTTP resource waiter in lltexturefetch.
What I was doing before wasn't correct. Instead, I'm implementing the resource wait
after the Semaphore model (though not using system semaphores). So instead of having
a sequence like: SEND_HTTP_REQ -> WAIT_HTTP_RESOURCE -> SEND_HTTP_REQ, we now
do WAIT_HTTP_RESOURCE -> WAIT_HTTP_RESOURCE2 (actual wait) -> SEND_HTTP_REQ. Works
well but the prioritized filling of the corehttp library needs some performance
work later.

Went through all the code and tried to document lock and thread usage
in the module. There's a huge comment block introducing all of this
at the beginning and I believe it's correct (though not quite complete).
Keep it updated, people. Added a new state, WAIT_HTTP_RESOURCE, that's
sort of a side-state of SEND_HTTP_REQ. If we hit a high-water mark
for HTTP requests, the extra are shunted to the new state once. Once
levels fall to a low-water mark, we run through a wait list of UUIDs,
sort the valid ones by priority and release them for service. This
keeps the HTTP layer busy while leaving the active queue shallow enough
that requests can still be re-prioritzed cheaply. Priority model
changed. The new state uses the PRIORITY_LOW mask, the old users
of _LOW are now at PRIORITY_NORMAL and sleepers woken up after an
external event are kicked off at PRIORITY_HIGH. This combination
along with the new state should avoid priority inversion and keep
things running without resorting to an infinite pipeline. New
state displays as "HTW" with green text in the texture console.
Request cancelation and worker run-down should now be more
correct but this edge case may need more attention.
