Header container moves from a vector of raw lines to a vector
of string pairs representing name/value pairs in headers. For
incoming headers, we normalize the name to lowercase and trim
it. Values are only left-trimmed. Outgoing headers are left
as-is. Simple find() method for the common case, forward and
reverse iterators for those few who need to do it themselves.
The HTTP status line (e.g. 'HTTP/1.1 200 Ok') is no longer treated
as a header to be returned to caller. Unit tests, as usual,
were a bear but they absolutely ensured outgoing HTTP header
conformance after the change. Grunt work paid off.
LLTextureFetch was also given a second options structure
for texture fetches. Same as the original but with header return
to caller requested. Baked textures should use this, the other
20,000 texture fetch requests should continue to use the original.
|
|
Added second mesh class as well as an asset upload class.
Refactored initialization to use less code and more data to
cleanly get http started. Modified mesh to use the new
http class for large requests (>2MB for now). Added additional
timeout setting to llcorehttp to distinguish connection timeout
from transport timeout and are now using transport timeout
values for large asset downloads that may need more time.

after delete, erase() on end() iterator, a few more like that.

classes (moved to Handlers).

Bleh, had some old initialization code in place that meant I was using
32 connections. (Always verify with 'netstat'...) Logic is now to
use 1/4 of MeshMaxConncurrentRequests to head in the direction of 8
at a time. Full count is used to implement a high-water level keeping
llcorehttp in work.
|
|
Conversion was mostly trivial. Did some refactoring in the conversion
of Responders to Handlers which eliminated 5X code replication. More
will be done especially as this is extended to deal with the various
possible combinations of 200/206/416 status for ranged gets. There are
a lot of thread races in the existing code, that is going to need some
real attention. And the scheduling/liveness logic in the thread
management bounces around from thread to thread wasting a lot of time
and using expensive synchronization. Much can be done here. But the
result is that the 8 connections in the Mesh corehttp class now perform
as did the 32 connections of the original. And that 32 actually looks
like it could bleed to over 64. So, progress...

Pull cpu-based metrics into llcorehttp work to enable A/B
testing. Simple merge.
|
|
First version running with all five downloaders converted. Not certain
all are functional yet and the whole thing is slow but it is running.
|
|
Initial work completed on linux, moving over to windows to do debug
and refinement. This includes 5/6 handlers based on existing responders
and use of llcorehttp for the mesh header fetch.
|
|
Normalize deadman timer's args on U64/F64. Internals remain the
same. Modify mesh to collect and output enhanced CPU metrics.
|
|
Integrated as a ctor-time option to LLDeadmanTimer and have mesh
use this mode for the stats I'm gathering.
|
|
Windows resolution isn't good enough for a strictly increasing
time test in the unit tests.
|
|
The http_texture_load example program has some cpu usage gathering
tools that should be generally useful and specifically for the
deadman switch. Port these into llcommon into new all-static
class LLProcInfo. Add unit test, etc.

One of the metrics calls was running in an LLCurl-owned thread
doing responder invocation. Deleted that invocation and will
do with the other safe ones. Added a boost signal on the
TeleportStarted message which is now used to restart the metrics
timer. I think I'd like to move the metric blob into a free-
standing entity later...
|
|
Timer interface violated my design rules and I paid for it
with clumsiness and silent errors. Cleaned it up mainly
removing the evil default values. Found better integration
points in the mesh downloader and it's producing fairly
consistent numbers on the MeshTest2 test region (about
5500 downloads, ~90 seconds, +/- 10 seconds). Will review
with davep and do an early timer stop on teleport which
invalidates a timing sequence.
