Id rather than sha1 hash, since that is rarely used in modern
certs. The previous form was storing trusted certs using an empty sha1
hash value as the key, which meant most certificates matched... not good.
Modify the LLCertException to pass certificate information back as
LLSD rather than an LLPointer<LLCertificate>, because when the
exception is being thown from the certificate constructor that results
in one of a couple of other exceptions (even refcounting won't save
you when the problem is that the thing you're pointing to never
finished coming into being properly).
Update the certificates in the llsechandler_basic_test to modern
conventions, and extend the classes to allow for an optional
validation date so that the test can use a fixed date. Also make all
the certificates include the plain text form for ease of reference.
Have the ::notifyLoadedMeshes() method doing correct locking
and stall avoidance at the same time. This method now does
lazy mutex lock acquisition (trylock()) and if it fails on
either, it gives up and comes back later. Capture the maximum
number of sequential failures and report this at the end of
the run in the log. (So far, with big mesh regions, I've
only seen 1s and 2s.) Locking/mutex requirements sorted in
other locations as well. LLMutex gets trylock() method as
well as new LLMutexTrylock scoped locking class. Clean up
some documentation, more to do.
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 copy construction behavior of Recordings to not zero out data
split measurement into event and sample, with sample representing
a continuous function
created separate constructor for static allocation of sampler buffer
fixed start/stop/resume semantics of samplers and added sampler time interval tracking
Two fairly simple conflicts: dead stats sending code in the
texture fetch code (new llcorehttp library) and the cleanup
code in llappviewer was moved around in 3.4.x.
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.
