* Yang 1.1 feature and if-feature according to RFC 7950 7.20.1 and 7.20.2.
* See https://github.com/clicon/clixon/issues/41
* Features are declared via CLICON_FEATURE in the configuration file.
* logical combination of features not implemented, eg if-feature "not foo or
* Identity without any identityref:s caused SEGV
* Clarified semantics of main yang module:
* -y option to commands MUST specify filename
* CLICON_YANG_MODULE_MAIN MUST specify a module
* yang_parse() changed to take either filename or module name and revision.
* Removed clicon_dbspec_name[_set]().
* Use yang_main_module_name() instead.
* Replaced yang_spec_main with yang_spec_parse_module
* Added yang_spec_parse_file
* If you used old event callbacks API, you need to switch to the streams API
* See clixon_stream.[ch]
* Old streams API which needs to be removed include:
* clicon_log_register_callback()
* subscription_add() --> stream_register()
* backend_notify() and backend_notify_xml() - use stream_notify() instead
* Example uses "NETCONF" stream instead of "ROUTING"
* Added timeout option -t for clixon_netconf - quit after max time.
* These generated the Makefile variables: clixon_DBSPECDIR, clixon_SYSCONFDIR, clixon_LOCALSTATEDIR, clixon_LIBDIR, clixon_DATADIR which have been replaced by generic autoconf variables instead.
* NOTE: Due to an error in the previous implementation, all XPATH calls on the form `x[a=str]` where `str` is a string (not a number or XML symbol), must be changed to: `x[a='str'] or x[a="str"]`
* This includes all calls to `xpath_vec, xpath_first`, etc.
* All calls to cli_copy_config in CLI spec files must replace 2nd argument from `x[%s=%s]` to `x[%s='%s']`
* The old API is stillenabled. To define the new, define XPATH_USE_NEW in include/clixon_custom.h and recompile
* A typical call is: show @datamodel:example, cli_show_auto("candidate", "json");
* The example contains a more elaborate example.
* Thanks ngashok for request, see https://github.com/clicon/clixon/issues/24
* Previous support did no validation of values.
* Validation of types and CLI expansion
* Example extended with inclusion of iana-if-type RFC 7224 interface identities
* CLICON_NACM_MODE config option, default is disabled.
* Added username attribute to all rpc:s from frontend to backend
* Added NACM backend module in example
* Backend RPC register callback function (Netconf RPC or restconf operation POST) has been changed from: `backend_rpc_cb_register()` to `rpc_callback_register()`
* Backend RPC callback signature has been changed from: `int cb(clicon_handle h, cxobj *xe, struct client_entry *ce, cbuf *cbret, void *arg)` has been changed to : `int cb(clicon_handle h, cxobj *xe, struct client_entry *ce, cbuf *cbret, void *arg)`
* Frontend netconf and restconf plugins can register callbacks as well with same API as backends.
* For preparation for authorization RFC8341
* Plugins add clixon_plugin_init() and api struct for function pointers, eg:
```
static const struct clixon_plugin_api api = {
"example",
clixon_plugin_init,
...
}
clixon_plugin_api *clixon_plugin_init(clicon_handle h)
{
return (void*)&api;
}
```
* Moved specific plugin functions from apps/ to generic functions in lib/
* New generic plugin load function: clixon_plugins_load()
* Removed client-local netconf plugins netconf_plugin_callbacks()
* This was code used before generic YANG rpc calls
* Added username to clixon handle:
* clicon_username_get() / clicon_username_set()
* Added authentication plugin callback
* Removed some obscure plugin code that seem not to be used (please report if needed!)
* CLI parse hook
* CLICON_FIND_PLUGIN
* clicon_valcb()
* Removed username to rpc calls (added below)
* Builds and installs a new restconf library: libclixon_restconf.so and clixon_restconf.h
* The restconf library can be included by a restconf plugin.
* Example code in example/Makefile.in and example/restconf_lib.c
* Authorization
* Example extended with authorization
* Test added with http basic authorization (test/test_auth.sh)
* Documentation in FAQ.md
* README.md extended with new yang, netconf, restconf, datastore, and auth sections.
statements and identifying them as extensions or not. However,
semantics for specific extensions must still be added.
* Renamed ytype_id and ytype_prefix to yarg_id and yarg_prefix, respectively
* Added cli_show_version()
