Typedef Documentation

typedef struct h2_req_engine h2_req_engine

typedef void http2_output_consumed(void *ctx, conn_rec *c, apr_off_t consumed)

typedef apr_status_t http2_req_engine_init(h2_req_engine *engine, const char *id, const char *type, apr_pool_t *pool, apr_size_t req_buffer_size, request_rec *r, http2_output_consumed **pconsumed, void **pbaton)

Initialize a h2_req_engine. The structure will be passed in but only the name and master are set. The function should initialize all fields.

Parameters

engine	the allocated, partially filled structure
r	the first request to process, or NULL

Function Documentation

void http2_get_num_workers	(	server_rec *	s,
		int *	minw,
		int *	max
	)

int http2_is_h2

(

conn_rec *

)

An optional function which returns non-zero if the given connection or its master connection is using HTTP/2.

void http2_req_engine_done	(	h2_req_engine *	engine,
		conn_rec *	rconn,
		apr_status_t	status
	)

apr_status_t http2_req_engine_pull	(	h2_req_engine *	engine,
		apr_read_type_e	block,
		int	capacity,
		request_rec **	pr
	)

Get a new request for processing in this engine.

Parameters

engine	the engine which is done processing the slave
block	if call should block waiting for request to come
capacity	how many parallel requests are acceptable
pr	the request that needs processing or NULL

Returns

APR_SUCCESS if new request was assigned APR_EAGAIN if no new request is available APR_EOF if engine may shut down, as no more request will be scheduled APR_ECONNABORTED if the engine needs to shut down immediately

apr_status_t http2_req_engine_push	(	const char *	engine_type,
		request_rec *	r,
		http2_req_engine_init *	einit
	)

Push a request to an engine with the specified name for further processing. If no such engine is available, einit is not NULL, einit is called with a new engine record and the caller is responsible for running the new engine instance.

Parameters

engine_type	the type of the engine to add the request to
r	the request to push to an engine for processing
einit	an optional initialization callback for a new engine of the requested type, should no instance be available. By passing a non-NULL callback, the caller is willing to init and run a new engine itself.

Returns

APR_SUCCESS iff slave was successfully added to an engine

char* http2_var_lookup	(	apr_pool_t *	,
		server_rec *	,
		conn_rec *	,
		request_rec *	,
		char *
	)

The http2_var_lookup() optional function retrieves HTTP2 environment variables.
