7.1.0

3 July 2024

The 7.1.0 release features RESTCONF notifications for native mode,
multi-datastore, and many new configure options.

Features

  • RESTCONF notification for native mode
    • Previously only for FCGI
    • The following does not work: Regular subscription + stop-time
  • Optimization of yang schema mount: share yang-specs if all YANGs are equal

  • Changed datastore modstate to be last in file, as prior to 7.0
  • Event priority. Backend socket has higher prio
  • Multi-datastore
    • You can split configure datastore into multiple sub-files
    • On edit, only changed sub-files are updated.
    • Curently only implemented for mount-points
  • Code for SHA digests.
  • Option for automatic lock of datastore on edit-config
  • Option to set default CLI output format
  • CLI support for multiple inline commands separated by semi-colon
  • New clixon-config@2024-04-01.yang revision
    • Added options:
      • CLICON_NETCONF_DUPLICATE_ALLOW: Disable duplicate check in NETCONF messages
      • CLICON_LOG_DESTINATION: Default log destination
      • CLICON_LOG_FILE: Which file to log to if file logging

    • Added: debug bits type
    • Added: xmldb-split extension
    • Added: Default format

API changes on existing protocol/config features

Users may have to change how they access the system

  • Changed intermediate version numbers to be git-style, eg 7.0.0-39 instead of 7.1.0-PRE
  • If CLICON_XMLDB_MULTI is set, datastores are stored in a new directory
    • Previously: CLICON_XMLDB_DIR/<db>_db
    • New: CLICON_XMLDB_DIR/<db>d/
    • In particular, the top-level is moved from <db>_db to <db>.d/0.xml
    • Backward-compatible:
      • If backend is started with -s startup or -s running then <db>_db is read if <db>.d/0.xml is not found
  • Autoconf: Openssl mandatory for all configure, not only restconf, due to digest code

C/CLI-API changes on existing features

Developers may need to change their code

  • XML encoding added a quotes parameter for attribute encoding, update as follows:
    • xml_chardata_encode(e, fmt,...) --> xml_chardata_encode(e, 0, fmt,...)
    • xml_chardata_cbuf_append(cb, str) --> xml_chardata_cbuf_append(cb, 0, str)

6.1.0

19 Feb 2023

The Clixon 6.1 release completes Network monitoring (RFC 6022) and introduces a first version of YANG schema mount (RFC 8528). The main focus has been interoperability and basic support for the ongoing Clixon controller work.

New features

  • YANG schema mount RFC 8528
    • The primary use-case is the clixon-controller but can be used independently
    • New plugin callback: ca_yang_mount
      • To specify which YANG modules should be mounted
    • New plugin callback: ca_yang_patch
      • A method to patch a YANG module
    • To enable yang mounts, set new option CLICON_YANG_SCHEMA_MOUNT to true
    • Restrictions:
      • Only schema-ref=inline, not shared-schema
      • Mount-points must be presence containers, regular containers or lists are not supported.
  • Netconf monitoring RFC 6022
    • This is part 2, first part was in 6.0
    • Datastores, sessions and statistics
      • Added clixon-specific transport identities: cli, snmp, netconf, restconf
      • Added source-host from native restonf, but no other transports
      • Hello statistics is based on backend statistics, hellos from RESTCONF, SNMP and CLI clients are included and dropped external NETCONF sessions are not
      • RFC 6022 "YANG Module for NETCONF Monitoring"
    • See Feature Request: Support RFC 6022 (NETCONF Monitoring)

API changes on existing protocol/config features

Users may have to change how they access the system

  • Obsolete config options given in the configuration file are considered an error
  • New clixon-config@2022-12-01.yang revision
    • Added option: 'CLICON_YANG_SCHEMA_MOUNT`
    • Removed obsolete option: CLICON_MODULE_LIBRARY_RFC7895
  • clixon-lib,yang
    • Moved all extended internal NETCONF attributes to the clicon-lib namespace
      • These are: content, depth, username, autocommit, copystartup, transport, source-host, objectcreate, objectexisted.
    • The internal attributes are documented in https://clixon-docs.readthedocs.io/en/latest/netconf.html
  • With-defaults default retrieval mode has changed from REPORT-ALL to EXPLICIT
    • This means that all get operations without with-defaults parameter do no longer
      return implicit default values, only explicitly set values.
    • Applies to NETCONF <get>, <get-config> and RESTCONF GET
    • To keep backward-compatible behavior, define option NETCONF_DEFAULT_RETRIEVAL_REPORT_ALL in include/clixon_custom.h
    • Alternatively, change all get operation to include with-defaults parameter report-all

C/CLI-API changes on existing features

Developers may need to change their code

      • Example change:
        • xml2xpath(x, n, xp) -> xml2xpath(x, n, 0, xp)
    • xml_bind_*() functions: Added clicon_handle h as first parameter
      • Example change:
