New API is as follows:
* `clixon_xml2file()` - Print internal tree as XML to file
* `clixon_xml2cbuf()` - Print internal tree as XML to buffer
* `clixon_json2file()` - Print internal tree as JSON to file
* `clixon_json2cbuf()` - Print internal tree as JSON to buffer
* `clixon_cli2file()` - Print internal tree as CLI format to file
* `clixon_txt2file()` - Print internal tree as text format to file
* Added `skiptop` parameter, if set only apply to children of a node, skip top node
* default is 0
* Functions are merged, ie removed and replaced with more generic functions
* `xml2json_cbuf()`: Added `skiptop` parameter: `xml2json_cbuf(..., int skiptop)`
* `xml2json()` and `xml2json_cb()` merged into `xml2json_file()` with `skiptop`
* Replace `xml2json(...)` with `xml2json_file(..., stdout, 0)`
* Replace `xml2json_cb(...)` with `xml2json_file(..., 0)`
* `clicon_xml2cbuf()`: Added `skiptop` parameter: `clicon_xml2cbuf(..., int skiptop)`
* `xml2cli()`: Added `skiptop` parameter: `xml2cli(..., int skiptop)`
* Load/save JSON config file did not work
* Added rfc7951 parameter to `clixon_json_parse_string()` and `clixon_json_parse_file()`
* If set, honor RFC 7951: JSON Encoding of Data Modeled with YANG, eg it requires module name prefixes
* If not set, parse as regular JSON
* Test: added test_db.sh for datastore format tests
* Updated command-line usage of cli,netconf,backend apps in sync with clixon-docs user manual
* Documented differences between protocol stubs for external vs internal netconf
Changed semantics of locking: instead of relying of locking running-db,
an automatic lock bound to a session is maintained. When the session closes
the lock is released.
code not used (eg remaining) and avoiding an extra xpath_vec call.
Moved debug prints from plugin-callback-one to plugin-callback-all
Fixed memory error in data-cvec access function
* Merge branch 'dcornejo-master'
* Broke out pagination callback API from state data callbacks
* New pagination callback API uses new dispatcher from netgate, thanks @dcornejo
* Register callback with: `clixon_pagination_cb_register()`
* Use accessor functions `pagination_offset()`, `pagination_limit()`, etc
* Reverted state data callback API to pre-5.3 (see C/CLI API changes below)
* You need to change all statedata plugin callback for the new pagination feature
* If you dont use pagination you can ignore the values of the new parameters
* See [User manual pagination](https://clixon-docs.readthedocs.io/en/latest/misc.html#pagination)
* The updated callback signature is as follows:
```
int statedata(clicon_handle h,
cvec *nsc,
char *xpath,
pagination_mode_t pagmode, // NEW
uint32_t offset, // NEW
uint32_t limit, // NEW
uint32_t *remaining, // NEW
cxobj *xstate)
```
* The new callback contains parameters for paging
* Goal is to replace ca_statedata callback
* New plugin callback when lock/unlock occurs
* Add `ca_lockdb` tro plugin init to use it.
* Fixed: Typing 'q' in CLI more paging did not properly quit output
* Output continued but was not shown, for a very large file this could cause considerable delay
* Fixed: Lock was broken in first get get access
* if the first netconf operation to a backend was lock;get;unlock, the lock was broken in the first get access.
* 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()`
* This is an alternative to manage a clixon daemon via sudtemd, containerd or other
* One important special case is starting the clixon-restconf daemon internally
* This is how it works:
* Register a process via `clixon_process_register(h, name, namespace, argv, argc)`
* Use process-control RPC defined in clixon-lib.yang to start/stop/restart or query status on that process
* Example code in the main example
* Added: autocli-op extension (see new features)
* Added: rpc process-control for process/daemon management
* Added enable flag and removed presence in clixon-restconf
The `xmldb_put` is failing due to the `x_spec` field not being set on the xml tree (`xt`) due to no yang spec being passed to the `clixon_xml_parse_string` function.
* Only requests on the form: `<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><edit-config>...` will be accepted
* All replies will be on the form: `<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">...`
* Requests such as: `<rpc><edit-config>...` will not be accepted.
* You can revert this behaviour (to clixon pre-4.6 behaviour) by enabling `CLICON_NAMESPACE_NETCONF_DEFAULT`
* This API change is a consequence of: [copy-config's RPC cxobj parameter does not contain namespace #131](https://github.com/clicon/clixon/issues/131)
* In summary, a user registers an upgrade callback per module. The callback is called at startup if the module is added, has been removed or if the revision on file is different from the one in the system.
* The register function has removed `from` and `rev` parameters: `upgrade_callback_register(h, cb, namespace, arg)`
* The callback function has a new `op` parameter with possible values: `XML_FLAG_ADD`, `XML_FLAG_CHANGE` or `XML_FLAG_CHANGE`: `clicon_upgrade_cb(h, xn, ns, op, from, to, arg, cbret)`
