Field Documentation

◆ add_notify_callback

int(* cib_api_operations_s::add_notify_callback) (cib_t *cib, const char *event, void(*callback)(const char *event, xmlNode *msg))

Definition at line 132 of file cib_types.h.

◆ bump_epoch

int(* cib_api_operations_s::bump_epoch) (cib_t *cib, int call_options)

Definition at line 161 of file cib_types.h.

◆ client_id

int(* cib_api_operations_s::client_id) (const cib_t *cib, const char **async_id, const char **sync_id)

Get the given CIB connection's unique client identifier(s)

These can be used to check whether this client requested the action that triggered a CIB notification.

Parameters
[in]cibCIB connection
[out]async_idIf not NULL, where to store asynchronous client ID
[out]sync_idIf not NULL, where to store synchronous client ID
Returns
Legacy Pacemaker return code
Note
Some variants may have only one client for both asynchronous and synchronous requests.

Definition at line 229 of file cib_types.h.

◆ create

int(* cib_api_operations_s::create) (cib_t *cib, const char *section, xmlNode *data, int call_options)

The <failed> element in the reply to a failed creation call is deprecated since 2.1.8.

Definition at line 167 of file cib_types.h.

◆ del_notify_callback

int(* cib_api_operations_s::del_notify_callback) (cib_t *cib, const char *event, void(*callback)(const char *event, xmlNode *msg))

Definition at line 137 of file cib_types.h.

◆ end_transaction

int(* cib_api_operations_s::end_transaction) (cib_t *cib, bool commit, int call_options)

End and optionally commit this client's CIB transaction.

When a client commits a transaction, all requests in the transaction are processed in a FIFO manner until either a request fails or all requests have been processed. Changes are applied to a working copy of the CIB. If a request fails, the transaction and working CIB copy are discarded, and an error is returned. If all requests succeed, the working CIB copy replaces the initial CIB copy.

Callbacks and notifications can be triggered by the commit request itself but not by the individual requests in a transaction.

An end_transaction() call with commit set to false is always synchronous.

Parameters
[in,out]cibCIB connection
[in]commitIf true, commit transaction; otherwise, discard it
[in]call_optionsGroup of enum cib_call_options flags
Returns
Legacy Pacemaker return code

Definition at line 292 of file cib_types.h.

◆ fetch_schemas

int(* cib_api_operations_s::fetch_schemas) (cib_t *cib, xmlNode **output_data, const char *after_ver, int call_options)

Definition at line 306 of file cib_types.h.

◆ free

int(* cib_api_operations_s::free) (cib_t *cib)

Definition at line 129 of file cib_types.h.

◆ init_transaction

int(* cib_api_operations_s::init_transaction) (cib_t *cib)

Initiate an atomic CIB transaction for this client.

If the client has initiated a transaction and a new request's call options contain cib_transaction, the new request is appended to the transaction for later processing.

Supported requests are those that meet the following conditions:

  • can be processed synchronously (with any changes applied to a working CIB copy)
  • are not queries
  • do not involve other nodes
  • do not affect the state of the CIB manager itself

Currently supported CIB API functions include:

Because the transaction is atomic, individual requests do not trigger callbacks or notifications when they are processed, and they do not receive output XML. The commit request itself can trigger callbacks and notifications if any are registered.

An init_transaction() call is always synchronous.

Parameters
[in,out]cibCIB connection
Returns
Legacy Pacemaker return code
