[Bug Report] Wrong Unlock #336
Description
if you try
TrinityConfig.CurrentRunningMode = RunningMode.Client;
try {
KCoreCell node_ins = Global.CloudStorage.LoadKCoreCell(0);
}
catch (Exception ex) {
Console.WriteLine("cell not found");
}
var neighbors = new List<long>();
Global.CloudStorage.SaveKCoreCell(0, alive: false, remain_nodes: 0, neighbors);
this code the server will break this is for in
#region LoadCell
tupleList.Add(new TypeSyncRequestResponseHandlerTuple
{
Id = (ushort)RequestType.LoadCell,
Handler = delegate(SynReqRspArgs args)
{
int index, cellSize;
byte* cellPtr = null;
TrinityErrorCode eResult;
long cellId = *(long*)(args.Buffer + args.Offset);
if ((eResult = CLocalMemoryStorage.CGetLockedCellInfo4LoadCell(cellId, out cellSize, out cellPtr, out index)) == TrinityErrorCode.E_CELL_NOT_FOUND)
{
args.Response = new TrinityMessage(eResult);
}
else
{
args.Response = new TrinityMessage(eResult, cellSize);
Memory.memcpy(args.Response.Buffer + TrinityMessage.Offset, cellPtr, (ulong)cellSize);
}
Log.WriteLine(LogLevel.Info, "Load Crelease lock {0} id {1} index", cellId, index);
CLocalMemoryStorage.CReleaseCellLock(cellId, index);
}
});
The storage will release the lock. But in load process there don't exit any lock on the cell.
uint8_t MTHash::ReleaseEntryLock(const int32_t index)
{
if (TrinityConfig::ReadOnly())
return 0;
Trinity::Diagnostics::WriteLine(Trinity::Diagnostics::Info, "UnKnow Release index {0} LOCK {1}", index, (int)MTEntries[index].EntryLock);
return (MTEntries[index].EntryLock.fetch_add(-1, std::memory_order_release) - 1);
}
this code will put the entrylock into -1.
