The former is important +in case the host is sending a constant stream of POST codes. +post-code-manager can fall behind because it takes too long to store +each new POST code on disk, causing D-Bus messages to pile up and +increase memory consumption inside dbus-broker. + +Tested: +Rebooted the host a few times and observed that POST code history is +populated normally in Redfish. After upgrading to this change, old POST +code history stored in JSON format is lost, but remains on disk until it +gets overwritten during subsequent host boots. + +Signed-off-by: Jonathan Doman <jonathan.doman@intel.com> +Change-Id: Id55909a55d950e6e62b78b3333df687b4c582c42 +Signed-off-by: Manish Baing <manish.baing@intel.com> +--- + inc/post_code.hpp | 6 ------ + src/post_code.cpp | 17 ++++++++++++----- + 2 files changed, 12 insertions(+), 11 deletions(-) + +diff --git a/inc/post_code.hpp b/inc/post_code.hpp +index be800f2..3d790b8 100644 +--- a/inc/post_code.hpp ++++ b/inc/post_code.hpp +@@ -18,12 +18,6 @@ + #include <fcntl.h> + #include <unistd.h> + +-#include <cereal/access.hpp> +-#include <cereal/archives/json.hpp> +-#include <cereal/cereal.hpp> +-#include <cereal/types/map.hpp> +-#include <cereal/types/tuple.hpp> +-#include <cereal/types/vector.hpp> + #include <chrono> + #include <filesystem> + #include <fstream> +diff --git a/src/post_code.cpp b/src/post_code.cpp +index 1fcbe55..dfe6ce7 100644 +--- a/src/post_code.cpp ++++ b/src/post_code.cpp +@@ -17,6 +17,13 @@ + + #include "iomanip" + ++#include <cereal/access.hpp> ++#include <cereal/archives/binary.hpp> ++#include <cereal/cereal.hpp> ++#include <cereal/types/map.hpp> ++#include <cereal/types/tuple.hpp> ++#include <cereal/types/vector.hpp> ++ + PostCodeDataHolder* PostCodeDataHolder::instance = 0;
