From c19cbca69e53e5b07777aba7464fdb3e11d3fc47 Mon Sep 17 00:00:00 2001 From: Praveen Chaudhary Date: Mon, 2 Dec 2019 18:10:09 -0800 Subject: [PATCH 01/10] [_sonic_yang_ext.py]: Extend sonic yang class to support cropping of config. From the json format of yang models, a map is created from config DB tables to container in yang model. Input Config is cropped on based of this map. --- src/sonic-yang-mgmt/_sonic_yang_ext.py | 210 +++++++++++++++++++++++++ src/sonic-yang-mgmt/sonic_yang.py | 50 ++++-- 2 files changed, 243 insertions(+), 17 deletions(-) create mode 100644 src/sonic-yang-mgmt/_sonic_yang_ext.py diff --git a/src/sonic-yang-mgmt/_sonic_yang_ext.py b/src/sonic-yang-mgmt/_sonic_yang_ext.py new file mode 100644 index 000000000000..78983a2fd40e --- /dev/null +++ b/src/sonic-yang-mgmt/_sonic_yang_ext.py @@ -0,0 +1,210 @@ +# This script is used as extension of sonic_yang class.

[PATCH 05/10] [_sonic_yang_ext.py]: Reverse translation i.e. from YANG json to Config DB json. Reverse translation i.e. from YANG json to Config DB json based on yang models. Find xpath for a port. portleaf and a yang list. get_data functions to get rev xlated data from data tree.
