Hello experts,
I am using protobuf library to report KPIs for my project. It cores in
SerializationToString() under load. While running under valgrind, i found
Invalid Read in protobuf code. My application is single threaded.
I use Reflection API to set/reset values in Map.
*Here is my proto file.*
message Hi2IriStatsData
{
message PerCFStats
{
string cfid = 1; // The CFID
uint32 ifid = 2; // The IFID
string cftype = 3; // The CF TYPE (as configured in
the CF MO table).
string destip = 4;
string destport = 5;
uint32 total_lisco_rcvd = 10;
uint32 curr_lisco_rcvd = 11;
uint32 total_iri_dlvd = 30;
uint32 curr_iri_dlvd = 31;
uint32 total_iri_dropped = 40;
uint32 curr_iri_dropped = 41;
uint32 total_calls_dlvd = 50;
uint32 curr_calls_dlvd = 51;
int32 hi2_connections = 90;
google.protobuf.Timestamp last_iri_dlvd_time = 110;
}
message PerTargetStats
{
string coid = 1;
uint32 tid = 2;
string caseid = 3;
uint32 curr_iri_dlvd = 40;
uint32 curr_iri_dropped = 41;
uint32 curr_calls_dlvd = 50;
}
/* These are the stats */
map<string, PerCFStats> cf_stats = 1; // Key is <CFID IFID>
(i.e. cfid space and ifid)
map<string, PerTargetStats> tgt_stats = 5; // Key is <coid tid>
(i.e. coid space and tid)
}
