## 4.5.0
Expected: May 2020
12 May 2020
The 4.5.0 release introduces xpaths in the NACM implementation thus
completing the RPC and Data node access. There has also been several
optimizations. Note that this version must be run with CLIgen 4.5, it
cannot run with CLIgen 4.4 or earlier.
### Major New features
@ -35,7 +40,7 @@ Expected: May 2020
* 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.
### API changes on existing protocol/config features (For users, you may have have to change how you use Clixon)
### API changes on existing protocol/config features (For users)
* Stricter validation detecting duplicate container or leaf in XML.
* Eg `<x><a/><a/></x>` is invalid if `a` is a leaf or container.
@ -49,7 +54,7 @@ Expected: May 2020
* Stricter incoming RPC sanity checking, error messages may have changed.
* Changed output of `clixon_cli -G` option to show generated CLI spec original text instead of resulting parse-tree, which gives better detail from a debugging perspective.
### C-API changes on existing features (For developers: you may need to change your plugin C-code)
### C-API changes on existing features (For developers)
* Length of xml vector in many structs changed from `size_t` to `int`since it is a vector size, not byte size.
* Example: `transaction_data_t`
@ -61,24 +66,21 @@ Expected: May 2020
* `clicon_parse()`: Changed signature due to new cligen error and result handling:
* Removed: `cli_nomatch()`
### Minor changes
### Optimzations
* Optimized namespace prefix checks at xml parse time: using many prefixes slowed down parsing considerably
* Optimized cbuf handling in parsing and xml2cbuf functions: use of new `cbuf_append()` function.
* Optimized xml scanner to read strings rather than single chars
* Identify early that trees are disjunct instead of recursively merge in `xml_merge`
* Optimizations of `yang_bind` for large lists: use a "sibling/template" to use same binding as previous element.
* Reduced memory for attribute and body objects, by allocating less memory in `xml_new()` than for elements, reducing XML storage with ca 25%
* Cleared startup-db cache after restart, slashing datastore cache with (best-case) a third.
* Removed nameserver binding cache for leaf/leaf-list objects.
* Remove xml value cache after sorting (just use cligen value cache at sorting, remove after use)
### Minor changes
* Added decriptive error message when plugins produce invalid state XML.
* Example: `<error-tag>operation-failed</error-tag><error-info><bad-element>mystate</bad-element></error-info><error-message>No such yang module. Internal error, state callback returned invalid XML: example_backend</error-message>`
* Such a message means there is something wrong in the internal plugins or elsewehere, ie it is not a proper end-user error.
* Compile-time option: `USE_CLIGEN44` for running clixon-45 with cligen-44.
* Temporary fix since cligen-45 have some non-backward compatible behaviour.
* Cycle optimizations
* Optimized namespace prefix checks at xml parse time: using many prefixes slowed down parsing considerably
* Optimized cbuf handling in parsing and xml2cbuf functions: use of new `cbuf_append()` function.
* Optimized xml scanner to read strings rather than single chars
* Identify early that trees are disjunct instead of recursively merge in `xml_merge`
* Optimizations of `yang_bind` for large lists: use a "sibling/template" to use same binding as previous element.
* Memory optimizations
* Reduced memory for attribute and body objects, by allocating less memory in `xml_new()` than for elements, reducing XML storage with ca 25%
* Cleared startup-db cache after restart, slashing datastore cache with (best-case) a third.
* Removed nameserver binding cache for leaf/leaf-list objects.
* Remove xml value cache after sorting (just use cligen value cache at sorting, remove after use)
* Adapted to CLIgen 4.5 API changes, eg: `cliread()` and `cliread_parse()`
* Renamed utility function `clixon_util_insert()` to `clixon_util_xml_mod()` and added merge functionality.
* Sanity check of duplicate prefixes in Yang modules and submodules as defined in RFC 7950 Sec 7.1.4
