migrate mac-address python validator to validate-value Instead of spawning the Python interpreter for every mac-address to validate, rather use the base validate-value OCaml implementation which is much faster. This removes redundant code and also makes the CLI more responsive. Validator is moved out to a dedicated file instead of using XML inlined for the reason of re-usability. So if that regex needs to be touched again - it can all happen in one single file. --- .../include/firewall/mac-address.xml.i | 5 ++-- src/validators/mac-address | 29 ++-------------------- src/validators/mac-address-exclude | 2 ++ src/validators/mac-address-firewall | 27 -------------------- 4 files changed, 7 insertions(+), 56 deletions(-) create mode 100755 src/validators/mac-address-exclude delete mode 100755 src/validators/mac-address-firewall (limited to 'interface-definitions/include') diff --git a/interface-definitions/include/firewall/mac-address.xml.i b/interface-definitions/include/firewall/mac-address.xml.i index 83aaf1ce1..db3e1e312 100644 --- a/interface-definitions/include/firewall/mac-address.xml.i +++ b/interface-definitions/include/firewall/mac-address.xml.i @@ -3,7 +3,7 @@ MAC address - macaddr; + macaddr MAC address to match @@ -11,7 +11,8 @@ Match everything except the specified MAC address - + + diff --git a/src/validators/mac-address b/src/validators/mac-address index 7d020f387..bb859a603 100755 --- a/src/validators/mac-address +++ b/src/validators/mac-address @@ -1,27 +1,2 @@ -#!/usr/bin/env python3 -# -# Copyright (C) 2018-2020 VyOS maintainers and contributors -# -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License version 2 or later as -# published by the Free Software Foundation. -# -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
