int h2_mplx_m_awaits_data ( h2_mplx * m )

apr_status_t h2_mplx_m_child_init	(	apr_pool_t *	pool,
		server_rec *	s
	)

apr_status_t h2_mplx_m_client_rst	(	h2_mplx *	m,
		int	stream_id
	)

h2_mplx* h2_mplx_m_create	(	conn_rec *	c,
		server_rec *	s,
		apr_pool_t *	master,
		struct h2_workers *	workers
	)

Create the multiplexer for the given HTTP2 session. Implicitly has reference count 1.

apr_status_t h2_mplx_m_dispatch_master_events	(	h2_mplx *	m,
		stream_ev_callback *	on_resume,
		void *	ctx
	)

Dispatch events for the master connection, such as ±

Parameters

m	the multiplexer
on_resume	new output data has arrived for a suspended stream
ctx	user supplied argument to invocation.

int h2_mplx_m_has_master_events ( h2_mplx * m )

Check if the multiplexer has events for the master connection pending.

Returns: != 0 iff there are events pending

apr_status_t h2_mplx_m_idle ( h2_mplx * m )

Master connection has entered idle mode.

Parameters

m	the mplx instance of the master connection

Returns: != SUCCESS iff connection should be terminated

apr_status_t h2_mplx_m_keep_active	(	h2_mplx *	m,
		struct h2_stream *	stream
	)

apr_status_t h2_mplx_m_out_trywait	(	h2_mplx *	m,
		apr_interval_time_t	timeout,
		struct apr_thread_cond_t *	iowait
	)

Waits on output data from any stream in this session to become available. Returns APR_TIMEUP if no data arrived in the given time.

apr_status_t h2_mplx_m_process	(	h2_mplx *	m,
		struct h2_stream *	stream,
		h2_stream_pri_cmp *	cmp,
		void *	ctx
	)

Process a stream request.

Parameters

m	the multiplexer
stream	the identifier of the stream
r	the request to be processed
cmp	the stream priority compare function
ctx	context data for the compare function

void h2_mplx_m_release_and_join	(	h2_mplx *	m,
		struct apr_thread_cond_t *	wait
	)

Decreases the reference counter of this mplx and waits for it to reached 0, destroy the mplx afterwards. This is to be called from the thread that created the mplx in the first place.

Parameters

m	the mplx to be released and destroyed
wait	condition var to wait on for ref counter == 0

apr_status_t h2_mplx_m_reprioritize	(	h2_mplx *	m,
		h2_stream_pri_cmp *	cmp,
		void *	ctx
	)

Stream priorities have changed, reschedule pending requests.

Parameters

m	the multiplexer
cmp	the stream priority compare function
ctx	context data for the compare function

int h2_mplx_m_shutdown ( h2_mplx * m )

Shut down the multiplexer gracefully. Will no longer schedule new streams but let the ongoing ones finish normally.

Returns: the highest stream id being/been processed

apr_status_t h2_mplx_m_stream_cleanup	(	h2_mplx *	m,
		struct h2_stream *	stream
	)

Notifies mplx that a stream has been completely handled on the main connection and is ready for cleanup.

Parameters

m	the mplx itself
stream	the stream ready for cleanup

apr_status_t h2_mplx_m_stream_do	(	h2_mplx *	m,
		h2_mplx_stream_cb *	cb,
		void *	ctx
	)

apr_status_t h2_mplx_s_pop_task	(	h2_mplx *	m,
		struct h2_task **	ptask
	)

void h2_mplx_s_task_done	(	h2_mplx *	m,
		struct h2_task *	task,
		struct h2_task **	ptask
	)

apr_status_t h2_mplx_t_out_open	(	h2_mplx *	mplx,
		int	stream_id,
		struct h2_bucket_beam *	beam
	)

Opens the output for the given stream with the specified response.

struct h2_stream* h2_mplx_t_stream_get	(	h2_mplx *	m,
		struct h2_task *	task
	)

Get the stream that belongs to the given task.
