* Internal NETCONF (client <-> backend)
* Ensure message-id increments
* Separated rpc from notification socket in same session
* Removed coverage icon from homepage since it stopped working some time ago
* Added flag names: `CLIXON_DBG_*`
* Added maskable flags that can be combined when debugging:
* `DEFAULT` = 1: Basic debug message, espcially initialization
* `MSG` = 2: Input and output packets, read datastore
* `DETAIL` = 4: Details: message dump in hex, xpath parse trees, etc
* `EXTRA` = 8: Extra detailed logs
* Test: some errors in yang-lib where content-id was in wrong place
- statistics and transport/source-host parameters
- extended internal NETCONF hello with transport and source-host attributes
clixon-lib,yang
- Moved all extended internal NETCONF attributes to the clicon-lib namespace
C-API:
- wrapped most attribute creation into new fn xml_add_attr()
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)`
* Fixed: [Error message seen twice in some cases](https://github.com/clicon/clixon/issues/325)
* Extended `-l` command-line option to all clixon commands with a `none` option, eg `-l n` directs logging to `dev/null`
* `-0` means dont send hello, but fix netconf base version to 0 and use EOM framing
* `-1` means dont send hello, but fix netconf base version to 1 and use chunked framing
Save state of netconf chunked framing between inputs
Treat EBADF in internal protocol (triggered by freebsd+notifications)
Test: chunked encoding: use printf instead of echo
* First hello is 1.0 EOM framing, then successing rpc is chunked framing
* See
* [Netconf framing](https://github.com/clicon/clixon/issues/50), and
* [Clixon does not switch to chunked framing after NETCONF 1.1 is negotiated](https://github.com/clicon/clixon/issues/314)
* C:
* Moved netconf framing code from netconf application to clixon lib
* Test:
* New expecteof_netconf and adjusted other expect scripts to handle NETCONF 1.1 framing
* Note that edits to the candidate database or locks will be lost
* To force the CLI to exit if backend restarts, undef `PROTO_RESTART_RECONNECT`
* This is an effect of the fix of [Broken pipe error seen in client (cli) when backend restarts and CLICON_SOCK is recreated](https://github.com/clicon/clixon/issues/312), the CLI behavior on backend restart is changed.
* Added `eof` parameter to `clicon_rpc()` and `clicon_rpc1()` and error handling modified
* 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
* Added ancestor config cache indicating wether the node or an ancestor is config false or true
* Improved yang cardinality lookup
* Added yang_init(), called from all apps using yang
* Stricter checking of outgoing RPC replies from server
* See [RPC output not verified by yang](https://github.com/clicon/clixon/issues/283)
* This lead to some corrections of RPC replies in system code
NETCONF hello errors, such as wrong session-id, prefix, namespace terminates session
* Instead of returning an rpc-error reply
Changed YANG PATCH enabling:
* Now: `./configure --enable-yang-patch`
* Before: set YANG_PATCH constant in `include/clixon_custom.h`
Refactored Makefile for static linking
Install libnghttp2-devel in ubuntu and centos per required dependencies
Ignore case when checking XML declaration encoding value per W3C recommendations
Fix filter logic to follow RFC6241 (7.1, 7.7) and default to subtree
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
