* Several cases were not implemented fully according to RFC 7950
* Do not extend default values if when statements evaluate to false
* Do not allow edit-config of nodes if when statements evaluate to false (Sec 8.3.2)
* If a key leaf is defined in a grouping that is used in a list, the "uses" statement MUST NOT have a "when" statement. (See 7.21.5)
* See [yang uses's substatement when has no effect #218](https://github.com/clicon/clixon/issues/2$
This include plugin module init and exit functions
New type: clixon_plugin_t exposed via public API while struct clixon_plugin is private
- Makefile changes for static linkage using "LINKAGE=static"
- Moved nacm external init to later stage in backend_main
* This means that files and datastores supporting modstate also looks for deleted or updated yang modules.
* A stricter binding which gives error if loading outdated YANG file does not exist.
* Stricter yang checks: you cannot do get-config on datastores that have obsolete YANG
* Added xerr output parameter to `xmldb_get0()`
- Restconf auth=none changes
- Load clixon-restconf and resolve features earlier so that config features work
- Removed auth=none code from example (this was non-std half-baked basic auth)
- Changed tests that used auth-type=none to enable feature clixon-restconf:allow-auth-none
- Moved cert creation from sub-shell to servercert function
- Fixed typos for dockerfile rename of restconf evhtp to native
* Fixed: [Augment that reference a submodule as target node fails #178](https://github.com/clicon/clixon/issues/178)
* Fixed a memory error that was reported in slack by Pawel Maslanka
* The crash printout was: `realloc(): invalid next size Aborted`
* Except `CLICON_RESTCONF_DIR` which remains in clixon-config.yang due to bootstrapping
* -d <dir> option removed
* This applies to both evhtp and fcgi RESTCONF
* Both can also read config from backend, and be started from backend
* You may need to move config as follows (from clixon-config.yang to clixon-restconf.yang)
* CLICON_RESTCONF_PRETTY -> restconf/pretty
* CLICON_RESTCONF_PATH -> restconf/fcgi-path
* Added new revision of main example yang: `clixon-example@2020-12-01.yang`
* Fixed [YANG: key statement in rpc/notification list #148](https://github.com/clicon/clixon/issues/148)
* Do not check uniqueness among lists without keys
* If-feature now supports and/or lists, such as: `if-feature "a and b"` and `if-feature "a or b or c"`. However, full if-feature-expr including `not` and nested boolean experessions is still not supported.
* Sanity check: if an `if-feature` statement exists, a corresponding `feature` statement must exists that declares that feature.
1. Added #ifdef extern "C" to public header files.
2. Changed variables that are key words in c++, to different names (like ns instead of namespace).
3. Changed char* to const char* for constant strings.
* A generated clispec including state (default @datanodestate) also generated along with the config clispec tree (default @datanode)
* New mode `GT_HIDE` set by option `CLICON_CLI_GENMODEL_TYPE` to collapse non-presence containers that only contain a single list
* Added a prfix for cli_show_config/cli_show_auto so that it can produce parseable output
* Thanks dcornejo@netgate.com for trying it out and suggestions
* Added: stats RPC for clixon XML and memory statistics.
* Added: restart-plugin RPC for restarting individual plugins without restarting backend.
* xml-stats moved from clixon-config.yang as state data to an rpc `datastats` in clixon-lib.yang
* Experimental: restart_plugin
* Two new plugin callbacks added
* ca_daemon: Called just after a server has "daemonized", ie put in background.
* ca_trans_commit_done: Called when all plugin commits have been done.
* Note: If you have used "end" callback and usign transaction data, you should probably use this instead.
* If fails, exit with error message, eg: `Yang error: Sanity check failed: LIST vsDataContainer lacks key statement which MUST be present (See RFC 7950 Sec 7.8.2)`
* Can be disabled by setting `CLICON_CLICON_YANG_LIST_CHECK` to `false`
