The wilcard part was always length driven... but the check part relied on
being NUL terminated. Change that to also use a length specifier and not
need any NUL.
To migrate old uses, just add a fourth param as strlen(check).
Trying to use the opaque pointer in the handle to point to the conn isn't
going to work when we need it to point to the ss handle.
Move it to have its on place in the handle.
Defer recording the ss metrics histogram until wsi close, so it has a
chance to collect all the tags that apply.
Defer dumping metrics until the FINALIZE phase of context destroy, so we
had a chance to get any metrics recorded.
There are a few build options that are trying to keep and report
various statistics
- DETAILED_LATENCY
- SERVER_STATUS
- WITH_STATS
remove all those and establish a generic rplacement, lws_metrics.
lws_metrics makes its stats available via an lws_system ops function
pointer that the user code can set.
Openmetrics export is supported, for, eg, prometheus scraping.
