From 30a530839cdbd934ea62369e385dc33fa50ab6de Mon Sep 17 00:00:00 2001 From: John Estabrook Date: Thu, 28 Mar 2024 14:34:20 -0500 Subject: config-sync: T6185: combine data for sections/configs in one command Package path/section data in single command containing a tree (dict) of section paths and the accompanying config data. This drops the call to get_config_dict and the need for a list of commands in request. --- python/vyos/configsession.py | 19 +++++++++++ src/helpers/vyos_config_sync.py | 66 ++++++++++++++++++++------------------- src/services/vyos-http-api-server | 38 ++++++++++++++++------ 3 files changed, 82 insertions(+), 41 deletions(-) diff --git a/python/vyos/configsession.py b/python/vyos/configsession.py index 90842b749..ab7a631bb 100644 --- a/python/vyos/configsession.py +++ b/python/vyos/configsession.py @@ -176,6 +176,25 @@ class ConfigSession(object): except (ValueError, ConfigSessionError) as e: raise ConfigSessionError(e) + def set_section_tree(self, d: dict): + try: + if d: + for p in dict_to_paths(d): + self.set(p) + except (ValueError, ConfigSessionError) as e: + raise ConfigSessionError(e) + + def load_section_tree(self, mask: dict, d: dict): + try: + if mask: + for p in dict_to_paths(mask): + self.delete(p) + if d: + for p in dict_to_paths(d): + self.set(p) + except (ValueError, ConfigSessionError) as e: + raise ConfigSessionError(e) + def comment(self, path, value=None): if not value: value = [""] diff --git a/src/helpers/vyos_config_sync.py b/src/helpers/vyos_config_sync.py index 77f7cd810..0604b2837 100755 --- a/src/helpers/vyos_config_sync.py +++ b/src/helpers/vyos_config_sync.py @@ -21,9 +21,11 @@ import json import requests import urllib3 import logging -from typing import Optional, List, Union, Dict, Any +from typing import Optional, List, Tuple, Dict, Any from vyos.config import Config +from vyos.configtree import ConfigTree +from vyos.configtree import mask_inclusive from vyos.template import bracketize_ipv6 @@ -61,39 +63,45 @@ def post_request(url: str, -def retrieve_config(section: Optional[List[str]] = None) -> Optional[Dict[str, Any]]: +def retrieve_config(sections: List[list[str]]) -> Tuple[Dict[str, Any], Dict[str, Any]]: """Retrieves the configuration from the local server.
