Detailed Description

Layer 6 (Presentation) — wires the transport ring buffer to the HTTP parser.

This file is now a thin adapter. The HTTP parsing logic lives in http_parser.cpp. This layer only knows about:

• The transport ring buffer (conn_pool[slot].rx_buffer / rx_head / rx_tail)
• Slot-indexed helpers that the session and application layers expect

The slot-indexed http_reset() pre-stamps slot_id then delegates to http_parser_reset(). The slot-indexed http_parse() drains all available bytes from the ring buffer through http_parser_feed() and stops as soon as the parser reaches any terminal state.

Function Documentation

http_reset()

void http_reset

(

uint8_t

slot_id

)

Reset the HTTP parser for a connection slot.

Reset a presentation-layer parser slot (Layer 6 forward decl).

Delegates to http_parser_reset(&http_pool[slot_id]). Silently ignores out-of-range slot IDs.

Parameters

slot_id

Index into conn_pool / http_pool (0 … MAX_CONNS-1).

http_parse()

void http_parse

(

uint8_t

slot_id

)

Drain the transport ring buffer and advance the HTTP parser.

Advance the HTTP parser for a slot (Layer 6 forward decl).

Reads all available bytes from conn_pool[slot_id].rx_buffer and feeds each byte to http_parser_feed(). Stops early if the parser reaches a terminal state (PARSE_COMPLETE, PARSE_ERROR, PARSE_ENTITY_TOO_LARGE, PARSE_URI_TOO_LONG).

Silently ignores out-of-range slot IDs.

Parameters

slot_id

Connection slot to parse.
