annotate src/http/v3/ngx_http_v3_parse.c @ 7836:2f900ae486bc quic
Debug cleanup.
+ all dumps are moved under one of the following macros (undefined by default):
NGX_QUIC_DEBUG_PACKETS
NGX_QUIC_DEBUG_FRAMES
NGX_QUIC_DEBUG_FRAMES_ALLOC
NGX_QUIC_DEBUG_CRYPTO
+ all QUIC debug messages got "quic " prefix
+ all input frames are reported as "quic frame in FOO_FRAME bar:1 baz:2"
+ all outgoing frames re reported as "quic frame out foo bar baz"
+ all stream operations are prefixed with id, like: "quic stream id 0x33 recv"
+ all transport parameters are prefixed with "quic tp"
(hex dump is moved to caller, to avoid using ngx_cycle->log)
+ packet flags and some other debug messages are updated to
include packet type
