static

Private definitions

Private functions Calls mpd_response_finish and checks for an mpd error and tries to recover.

Parameters

partition_state	pointer to partition specific states
buffer	already allocated sds string for the jsonrpc response or NULL
cmd_id	enum mympd_cmd_ids
request_id	jsonrpc request id to respond
response_type	response message type
command	command to check for the error

Returns

true on success, else false

mympd_check_error_and_recover()

bool mympd_check_error_and_recover	(	struct t_partition_state *	partition_state,
		sds *	error,
		const char *	command
	)

Checks for mpd protocol error and tries to recover it

Parameters

partition_state	pointer to partition specific states
error	pointer to an already allocated sds string for the error message or NULL
command	last mpd command

Returns

true on success, else false

mympd_check_error_and_recover_notify()

bool mympd_check_error_and_recover_notify	(	struct t_partition_state *	partition_state,
		sds *	buffer,
		const char *	command
	)

Checks for mpd protocol error and tries to recover it. Creates a jsonrpc notification on error.

Parameters

partition_state	pointer to partition specific states
buffer	already allocated sds string for the jsonrpc response or NULL
command	last mpd command

Returns

true on success, else false

mympd_check_error_and_recover_plain()

bool mympd_check_error_and_recover_plain	(	struct t_partition_state *	partition_state,
		sds *	buffer,
		const char *	command
	)

Checks for mpd protocol error and tries to recover it. Returns the plain mpd error message.

Parameters

partition_state	pointer to partition specific states
buffer	already allocated sds string for the mpd error message or NULL
command	last mpd command

Returns

true on success, else false

mympd_check_error_and_recover_respond()

bool mympd_check_error_and_recover_respond	(	struct t_partition_state *	partition_state,
		sds *	buffer,
		enum mympd_cmd_ids	cmd_id,
		unsigned	request_id,
		const char *	command
	)

Checks for mpd protocol error and tries to recover it. Creates a jsonrpc response on error.

Parameters

partition_state	pointer to partition specific states
buffer	pointer to an already allocated sds string for the jsonrpc response or NULL
cmd_id	enum mympd_cmd_ids
request_id	jsonrpc request id to respond
command	last mpd command

Returns

true on success, else false

mympd_clear_finish()

bool mympd_clear_finish

(

struct t_partition_state *

partition_state

)

Silently clears a recoverable MPD error

Parameters

partition_state

Pointer to partition state

Returns

true on success, else false

mympd_respond_with_error_or_ok()

sds mympd_respond_with_error_or_ok	(	struct t_partition_state *	partition_state,
		sds	buffer,
		enum mympd_cmd_ids	cmd_id,
		unsigned	request_id,
		const char *	command,
		bool *	result
	)

Checks for mpd protocol error and return code of last mpd command and tries to recover it. Creates always a jsonrpc response. Shortcut for mympd_check_rc_error_and_recover and jsonrpc_respond_ok

Parameters

partition_state	pointer to partition specific states
buffer	already allocated sds string for the jsonrpc response or NULL
cmd_id	enum mympd_cmd_ids
request_id	jsonrpc request id to respond
command	last mpd command
result	pointer to bool for result code

Returns

pointer to buffer

mympd_set_mpd_failure()

void mympd_set_mpd_failure	(	struct t_partition_state *	partition_state,
		const char *	errormessage
	)

Public functions Sets the MPD_FAILURE state for the partition. myMPD disconnects and tries a reconnect.

Parameters

partition_state	Pointer to partition state
errormessage	Error message to log
