_ncs.dp Module

Low level callback module for connecting data providers to NCS.

This module is used to connect to the NCS Data Provider API. The purpose of this API is to provide callback hooks so that user-written data providers can provide data stored externally to NCS. NCS needs this information in order to drive its northbound agents.

The module is also used to populate items in the data model which are not data or configuration items, such as statistics items from the device.

The module consists of a number of API functions whose purpose is to install different callback functions at different points in the data model tree which is the representation of the device configuration. Read more about callpoints in tailf_yang_extensions(5). Read more about how to use the module in the User Guide chapters on Operational data and External data.

This documentation should be read together with the confd_lib_dp(3) man page.

Functions

aaa_reload

aaa_reload(tctx) -> None

When the ConfD AAA tree is populated by an external data provider (see the AAA chapter in the User Guide), this function can be used by the data provider to notify ConfD when there is a change to the AAA data.

Keyword arguments:

• tctx -- a transaction context

access_reply_result

access_reply_result(actx, result) -> None

The callbacks must call this function to report the result of the access check to ConfD, and should normally return CONFD_OK. If any other value is returned, it will cause the access check to be rejected.

Keyword arguments:

• actx -- the authorization context

• result -- the result (ACCESS_RESULT_xxx)

action_delayed_reply_error

action_delayed_reply_error(uinfo, errstr) -> None

If we use the CONFD_DELAYED_RESPONSE as a return value from the action callback, we must later asynchronously reply. This function is used to reply with error.

Keyword arguments:

• uinfo -- a user info context

• errstr -- an error string

action_delayed_reply_ok

action_delayed_reply_ok(uinfo) -> None

If we use the CONFD_DELAYED_RESPONSE as a return value from the action callback, we must later asynchronously reply. This function is used to reply with success.

Keyword arguments:

• uinfo -- a user info context

action_reply_command

action_reply_command(uinfo, values) -> None

If a CLI callback command should return data, it must invoke this function in response to the cb_command() callback.

Keyword arguments:

• uinfo -- a user info context

• values -- a list of strings or None

action_reply_completion

action_reply_completion(uinfo, values) -> None

This function must normally be called in response to the cb_completion() callback.

Keyword arguments:

• uinfo -- a user info context

• values -- a list of 3-tuples or None (see below)

The values argument must be None or a list of 3-tuples where each tuple is built up like:

(type::int, value::string, extra::string)

The third item of the tuple (extra) may be set to None.

action_reply_range_enum

action_reply_range_enum(uinfo, values, keysize) -> None

This function must be called in response to the cb_completion() callback when it is invoked via a tailf:cli-custom-range-enumerator statement in the data model.

Keyword arguments:

• uinfo -- a user info context

• values -- a list of keys as strings or None

• keysize -- number of keys for the list in the data model

The values argument is a flat list of keys. If the list in the data model specifies multiple keys this list is still flat. The keysize argument tells us how many keys to use for each list element. So the size of values should be a multiple of keysize.

action_reply_rewrite

action_reply_rewrite(uinfo, values, unhides) -> None

This function can be called instead of action_reply_command() as a response to a show path rewrite callback invocation.

Keyword arguments:

• uinfo -- a user info context

• values -- a list of strings or None

• unhides -- a list of strings or None

action_reply_rewrite2

action_reply_rewrite2(uinfo, values, unhides, selects) -> None

This function can be called instead of action_reply_command() as a response to a show path rewrite callback invocation.

Keyword arguments:

• uinfo -- a user info context

• values -- a list of strings or None

• unhides -- a list of strings or None

• selects -- a list of strings or None

action_reply_values

action_reply_values(uinfo, values) -> None

If the action definition specifies that the action should return data, it must invoke this function in response to the cb_action() callback.

Keyword arguments:

• uinfo -- a user info context

• values -- a list of _lib.TagValue instances or None

action_set_fd

action_set_fd(uinfo, sock) -> None

Associate a worker socket with the action. This function must be called in the action cb_init() callback.

Keyword arguments:

• uinfo -- a user info context

• sock -- a previously connected worker socket

A typical implementation of an action cb_init() callback looks like:

class ActionCallbacks(object):
    def __init__(self, workersock):
        self.workersock = workersock

    def cb_init(self, uinfo):
        dp.action_set_fd(uinfo, self.workersock)

action_set_timeout

action_set_timeout(uinfo, timeout_secs) -> None

Some action callbacks may require a significantly longer execution time than others, and this time may not even be possible to determine statically (e.g. a file download). In such cases the /confdConfig/capi/queryTimeout setting in confd.conf may be insufficient, and this function can be used to extend (or shorten) the timeout for the current callback invocation. The timeout is given in seconds from the point in time when the function is called.

Keyword arguments:

• uinfo -- a user info context

• timeout_secs -- timeout value

action_seterr

If action callback encounters fatal problems that can not be expressed via the reply function, it may call this function with an appropriate message and return CONFD_ERR instead of CONFD_OK.

Keyword arguments:

• uinfo -- a user info context

• errstr -- an error message string

action_seterr_extended

action_seterr_extended(uninfo, code, apptag_ns, apptag_tag, errstr) -> None

• errstr -- an error message string

action_seterr_extended_info

action_seterr_extended_info(uinfo, code, apptag_ns, apptag_tag,
                            error_info, errstr) -> None

This function can be used to provide structured error information in the same way as action_seterr_extended(), and additionally provide contents for the NETCONF element.

Keyword arguments:

• errstr -- an error message string

auth_seterr

auth_seterr(actx, errstr) -> None

This function is used by the application to set an error string.

This function can be used to provide a text message when the callback returns CONFD_ERR. If used when rejecting a successful authentication, the message will be logged in ConfD's audit log (otherwise a generic "rejected by application callback" message is logged).

Keyword arguments:

• actx -- the auth context

• errstr -- an error message string

authorization_set_timeout

authorization_set_timeout(actx, timeout_secs) -> None

The authorization callbacks are invoked on the daemon control socket, and as such are expected to complete quickly. However in case they send requests to a remote server, and such a request needs to be retried, this function can be used to extend the timeout for the current callback invocation. The timeout is given in seconds from the point in time when the function is called.

Keyword arguments:

• actx -- the authorization context

• timeout_secs -- timeout value

data_set_timeout

data_set_timeout(tctx, timeout_secs) -> None

A data callback should normally complete quickly, since e.g. the execution of a 'show' command in the CLI may require many data callback invocations. In some rare cases it may still be necessary for a data callback to have a longer execution time, and then this function can be used to extend (or shorten) the timeout for the current callback invocation. The timeout is given in seconds from the point in time when the function is called.

Keyword arguments:

• tctx -- a transaction context

• timeout_secs -- timeout value

db_set_timeout

db_set_timeout(dbx, timeout_secs) -> None

Some of the DB callbacks registered via register_db_cb(), e.g. cb_copy_running_to_startup(), may require a longer execution time than others.

Keyword arguments:

• nctx -- notification context returned from register_notification_stream()

notification_reply_log_times

notification_reply_log_times(nctx, creation, aged) -> None

• values -- a list of _lib.TagValue instances or None

• path -- path to the parent of the notification in the data tree

notification_send_snmp

notification_send_snmp(nctx, notification, varbinds) -> None

Sends the SNMP notification specified by 'notification', without requesting inform-request delivery information. This is equivalent to calling notification_send_snmp_inform() with None as the cb_id argument.

Keyword arguments:

• nctx -- notification context returned from register_snmp_notification()

• notification -- the notification string

• varbinds -- a list of _lib.SnmpVarbind instances or None

notification_send_snmp_inform

• varbinds -- a list of _lib.SnmpVarbind instances or None

• cb_id -- callback id

• ref -- argument send to callbacks

notification_set_fd

notification_set_fd(nctx, sock) -> None

This function may optionally be called by the cb_replay() callback to request that the worker socket given by 'sock' should be used for the replay. Otherwise the socket specified in register_notification_stream() will be used.

Keyword arguments:

• nctx -- notification context returned from register_notification_stream()

• sock -- a previously connected worker socket

notification_set_snmp_notify_name

Keyword arguments:

• nctx -- notification context returned from register_snmp_notification()

• notify_name -- the snmpNotifyName

notification_set_snmp_src_addr

notification_set_snmp_src_addr(nctx, family, src_addr) -> None

By default, the source address for the SNMP notifications that are sent by the above functions is chosen by the IP stack of the OS. This function may be used to select a specific source address, given by src_addr, for the SNMP notifications subsequently sent using the nctx context. The default can be restored by calling the function with family set to AF_UNSPEC.

Keyword arguments:

• nctx -- notification context returned from register_snmp_notification()

• family -- AF_INET, AF_INET6 or AF_UNSPEC

• src_addr -- the source address in string format
