C/CLI-API changes on existing features

Developers may need to change their code

• Renamed clicon_strsep() --> clixon_strsep1()
• Changed signature of send hello function:
  • clixon_client_hello(s, d, v) -> clixon_client_hello(s, d, base10, base11, privcand)
• Change int to size_t in cxvec_append() and related functions and data-types
  • Calling types may need to be adjusted
• Modified and re-factor datastore API
  • Use API instead of direct access of db-elemnt struct
    • eg de->de_xml --> xmldb_cache_get(de)
  • clicon_db_elmnt_get() -> xmldb_find()
  • clicon_db_elmnt_set() is replaced by xmldb_new() but needs some rewrite
  • xmldb_get_cache(h, db, yb, xp, md, xe) -> xmldb_get_cache(h, db, xp, xe)
  • Use indirect access to candidate-db, eg
    • Instead of :
      candidate_commit(h, xe, "candidate",...)
    • do:
      xmldb_find_create(h, "candidate", ce->ce_id, &de, &db); candidate_commit(h, xe, db,...)
    • Same for candidate_validate()
• Modified and refactor rpc_msg API:
  • Replaced clicon_msg parameter with cbuf:
    • clicon_rpc_msg(h, msg,...) -> clicon_rpc_msg(h, cb,...)
    • clicon_rpc_msg_persistent(h, msg, ...) -> clicon_rpc_msg(h, cb, ...)
    • clicon_rpc(..., msg, &xret, eof) -> clixon_rpc11(..., cb, &cbret, eof)
  • Removed struct clicon_msg and clicon_msg_encode():
    • Replace:

       struct clicon_msg *msg=clicon_msg_encode(..., cbuf_get(cb));
       clicon_rpc_msg(h, msg, NULL);
    

    • With:

       clicon_rpc_msg(h, cb, NULL);
    

  • Change receive message handling to create cb:
    • clixon_msg_rcv10(..., cb, eof) -> clixon_msg_rcv10(..., &cb, eof)
    • clixon_rpc10(..., cb, eof) -> clixon_rpc10(, &cb, eof)
  • Rename rpc connect API:
    • clicon_rpc_connect() -> clixon_rpc_connect()
    • clicon_rpc_connect_unix() -> clixon_rpc_connect_unix()
    • clicon_rpc_connect_inet() -> clixon_rpc_connect_inet()

Corrected Bugs

• Fixed: RESTCONF GET/PUT across mountpoint for CLOSED device causes restconf_terminate
• Fixed: yang parsing of an identifier that is a multiline quoted string
• Fixed: Multiple deviations to same grouping when CLICON_YANG_USE_ORIGINAL doesnt work
• Fixed: YANG identityref from uses/grouping from separate module does not work
• Fixed: YANG error-app-tag identifies as error-message causing false duplicate
• Fixed: YANG error-app-tag not in range and length as it should
• Fixed: [https://github.com//issues/624](Circular YANG includes leads to SEGV)
• Fixed: Autocli of yang union if several elements are pattern strings may return ambiguos
• Fixed: YANG domain lost when parsing import/include YANGs
• Fixed: Restconf: Identity-refs in JSON RPC:s input statements did not work
• Fixed: Autocli: Completion in edit mode included other values
• Fixed: Restconf notification: Add "data:" as prefix to every line., not just first
• Fixed: memory error in rpc_get2 when error handling
• Fixed: RESTCONF crashes after sending request that ends with &
• Fixed: Do not use d_type from readdir()
