From 287ece64bf9a8ee0c42f77cefce559054b488ae7 Mon Sep 17 00:00:00 2001 From: George Liu Date: Thu, 30 Sep 2021 20:24:46 +0800 Subject: Remove NTPServers duplicate values and null values When saving the set NTPServers values from webUI, NTPServer may contain duplicate values and null values and update them to D-Bus. Now, need to parse and verify the value of the ntpServers attribute,and remove duplicate values and null values. Tested:save NTP and check it via D-Bus without this patch: NTPServers property as 3 "" "10.164.29.2" "10.164.29.2" with this patch: NTPServers property as 2 "" "10.164.29.2" Signed-off-by: George Liu Change-Id: I52291e4608efd635b179f3934c3d3e805afd2209 --- redfish-core/include/utils/stl_utils.hpp | 39 ++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 redfish-core/include/utils/stl_utils.hpp (limited to 'redfish-core/include/utils/stl_utils.hpp') diff --git a/redfish-core/include/utils/stl_utils.hpp b/redfish-core/include/utils/stl_utils.hpp new file mode 100644 index 0000000000..04d02cbada --- /dev/null +++ b/redfish-core/include/utils/stl_utils.hpp @@ -0,0 +1,39 @@ +#pragma once + +#include +#include + +namespace redfish +{ + +namespace stl_utils +{ + +template +ForwardIterator firstDuplicate(ForwardIterator first, ForwardIterator last) +{ + auto newLast = first; + + for (auto current = first; current != last; ++current) + { + if (std::find(first, newLast, *current) == newLast) + { + if (newLast != current) + { + *newLast = *current; + } + ++newLast; + } + } + + return newLast; +} + +template +void removeDuplicate(T& t) +{ + t.erase(firstDuplicate(t.begin(), t.end()), t.end()); +} + +} // namespace stl_utils +} // namespace redfish -- cgit v1.2.3
