New `ca_system_only` backend callback for reading system-only data
New `CLICON_XMLDB_SYSTEM_ONLY_CONFIG` configuration option
API: Added `system_only` parameter to clixon_xml2file1()
Cleared running on commit and inited candidate on startup with system-only data
Added callback code in main example
Added command-line timeout -t <sec> to restconf
Example: Added programmable timeout to backend example
Test: updated for fcgi and native using internal timeouts
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()`
