Functions

static int soap_wsrm_init (struct soap *soap, struct soap_wsrm_data *data, void *arg)
 Initializes plugin data.
 
static int soap_wsrm_copy (struct soap *soap, struct soap_plugin *p, struct soap_plugin *q)

 Deletes plugin data.
 
static int soap_wsrm_send (struct soap *soap, const char *buf, size_t len)
 Internal callback function to override fsend(). When the wsrm plugin is enabled, saves the message to the current sequence that is created at the client side. Allows unacknowledged messages to be resend with soap_wsrm_resend().

static int soap_wsrm_disconnect (struct soap *soap)
 Internal callback function to override fdisconnect(). Turns caching off, sets the cached message to NACK, and resets the server-side handle, so sequence can be deallocated later.

int soap_wsrm_create (struct soap *soap, const char *to, const char *replyto, LONG64 expires, const char *wsa_id, soap_wsrm_sequence_handle *seq)
 Creates a new sequence. Sequences are usually created by the sender (client) and confirmed by the receiver (server). The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to. A sequence ID is generated by the server upon success.
 
int soap_wsrm_create_offer (struct soap *soap, const char *to, const char *replyto, const char *id, LONG64 expires, enum wsrm__IncompleteSequenceBehaviorType behavior, const char *wsa_id, soap_wsrm_sequence_handle *seq)

The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to. A sequence ID is generated by the server upon success.

 Creates a new sequence by offering suggested WS-RM parameters to the WS-RM destination. Sequences are usually created by the sender (client) and confirmed by the receiver (server). The 'to' server address must be used for all messages of the sequence to be sent to the WS-RM destination server. Optionally the 'replyto' address can be given of the WS-RM source to reply to and an 'acksto' address can be given for acknowledgement messages to be sent to (normally to the reply to). A sequence ID is generated by the server upon success.
 
int soap_wsrm_request_num (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id, const char *wsa_action, ULONG64 num)
 Adds a WS-RM sequence message number to the next message transmitted. No acks are requested.
 
int soap_wsrm_request (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id, const char *wsa_action)
 Adds a WS-RM sequence message number to the next message transmitted to the WS-RM destination and increments the message counter by one. No acks are requested.
 
int soap_wsrm_request_acks (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id, const char *wsa_action)
 Adds a WS-RM sequence message number to the next message transmitted to the WS-RM destination and increments the message counter by one. Message acks for the current sequence are requested.
 
int soap_wsrm_check_retry (struct soap *soap, soap_wsrm_sequence_handle seq)
 Client-side check to verify if the remote call can be retried when a failure occured. Increases the robustness of messages sends, by ensuring that the message was at least transmitted (but not necessarily received). Also implements HTTP 307 Temporary Redirect. Retries are limited to SOAP_WSRM_MAX_RETRIES iterations.
 
int soap_wsrm_resend (struct soap *soap, soap_wsrm_sequence_handle seq, ULONG64 lower, ULONG64 upper)
 Client-side call to resend all non-acknowledged messages that were automatically cached for this sequence. Messages stored in the sequence for retransmission (those that were previously sent but not acknowledged) are resent to the soap_wsrm_to() address (which was set by soap_wsrm_create() or soap_wsrm_create_offer(), or the ReplyTo address). It is recommended to resend messages after the last message in the sequence was transmitted before closing the sequence. To reduce unnecessary resend attempts, it is recommended to use soap_wsrm_request_ack() with the last message to request acks for messages already delivered.
 
int soap_wsrm_close (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id)
 Closes the sequence, but does not yet terminate it. No new messages should be send, but messages can be resend with soap_wsrm_resend() if desired.
 
int soap_wsrm_terminate (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id)
 Terminates the sequence. No new messages should be send and no resends should be tried. Usually done after soap_wsrm_close() or any time to terminate the sequence prematurely.
 
int soap_wsrm_pulse (struct soap *soap, int timeout)
 Sends acknowledgements for all open sessions to all peers. Must set send and recv timeouts to prevent blocking.
 
int soap_wsrm_acknowledgement (struct soap *soap, soap_wsrm_sequence_handle seq, const char *wsa_id)
 Sends acknowledgements.
 
void soap_wsrm_seq_free (struct soap *soap, soap_wsrm_sequence_handle seq)
 Must be called to free the sequence allocated by soap_wsrm_create() or by soap_wsrm_create_offer(). Sequences created by soap_wsrm_create_offer return handles that are not automatically reclaimed by the engine.
 
const char * soap_wsrm_to (soap_wsrm_sequence_handle seq)
 Returns the endpoint address of the destination service that serves the sequence. Initially set with soap_wsrm_create or soap_wsrm_create_offer. HTTP 307 Temporary Redirect can change the endpoint during the lifetime of a message sequence. Thus, this function returns the most recent endpoint binding that can be used to send message to the server endpoint.
 
const char * soap_wsrm_acksto (soap_wsrm_sequence_handle seq)
 Returns the endpoint address of the AcksTo acknowledgement service that serves the sequence, when set with soap_wsrm_create() or soap_wsrm_create_offer() or NULL otherwise. HTTP 307 Temporary Redirect can change the endpoint during the lifetime of a message sequence. Thus, this function returns the most recent endpoint binding.
 
ULONG64 soap_wsrm_num (soap_wsrm_sequence_handle seq)
 Returns the current message number of the sequence.
 
ULONG64 soap_wsrm_nack (soap_wsrm_sequence_handle seq)
 Returns the number of non-acknowledged messages sent.
 
int soap_wsrm_check (struct soap *soap)

Also prepares the return WS-RM header. This function should be called in the each service operation that supports WS-RM. Do not use this function in a ReplyTo response-accepting destination service operation.
 
int soap_wsrm_reply_num (struct soap *soap, int flag)
 Prepares reply from service. When flag is set, adds a WS-RM sequence message number to the next message transmitted. No acks are requested. No WS-Addressing message relay.
 
int soap_wsrm_reply (struct soap *soap, const char *wsa_id, const char *wsa_action)
 Server-side server operation reply to be performed when the service operation returns. Server operations that support WS-Addressing and WS-RM must call this function to return normally (and/or allow the response message to be relayed as per WS-Addressing).
 
int soap_wsrm_reply_request_acks (struct soap *soap, const char *wsa_id, const char *wsa_action)
 Server-side server operation reply to be performed when the service operation returns. Message acks for the current sequence are requested, but only when client made a create sequence offer. Server operations that support WS-Addressing and WS-RM must call this function or call soap_wsrm_reply() to return normally (and/or allow the response message to be relayed as per WS-Addressing).
 
void soap_wsrm_cleanup (struct soap *soap)
 Cleans up all expired sequences and releases resources. To be used at the server side to periodically clean up WS-RM sequences. Server-side cleanup is automatic, as long as WS-RM is in use. Does not release client-side sequences allocated by soap_wsrm_create() or soap_wsrm_create_offer().

int soap_wsrm_resend ( struct soap *  soap,
soap_wsrm_sequence_handle  seq,
ULONG64  lower,

It is recommended to resend messages after the last message in the sequence was transmitted before closing the sequence. To reduce unnecessary resend attempts, it is recommended to use soap_wsrm_request_ack() with the last message to request acks for messages already delivered.
