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.
Change the default to not process multipart mime at SS layer.
If it's desired, then set "http_multipart_ss_in" true in the policy on the streamtype.
To test, use lws-minimal-secure-streams-avs, which uses SS processing as it is.
To check it without the processing, change #if 1 to #if 0 around the policy for
"http_multipart_ss_in" in both places in avs.c, and also enable the hexdump in ss_avs_metadata_rx()
also in avs.c, and observe the multipart framing is passed through unchanged.
Secure Streams is an optional layer on top of lws that separates policy
like endpoint selection and tls cert validation into a device JSON
policy document.
Code that wants to open a client connection just specifies a streamtype name,
and no longer deals with details like the endpoint, the protocol (!) or anything
else other than payloads and optionally generic metadata; the JSON policy
contains all the details for each streamtype. h1, h2, ws and mqtt client
connections are supported.
Logical secure streams outlive any particular connection and supports "nailed-up"
connectivity regardless of underlying connection stability.
