Hi again,
I think the problem is in the delete routine:
bool __fastcall ProxyCache::deleteFileFromRAMCacheWRTIndex(RAMFileCache
*bufferFileCache, bool alreadyMarkedAsToDelete)
{
if(!bufferFileCache)
return false;
if(bufferFileCache->cacheTreeNode)
{
RAMFileCacheIndex->Remove(bufferFileCache->cacheTreeNode);
bufferFileCache->cacheTreeNode = NULL;
}
cacheCurrentRAMSize -= bufferFileCache->getAndZeroSize(); // first time it
subtracts and then returns 0
if(!bufferFileCache->getWriteLock() && !bufferFileCache->getIsReadLock())
{
delete bufferFileCache;
return true;
}
else
{
if(!alreadyMarkedAsToDelete)
bufferFileCache->setDeleteFileASAP();
return false;
}
}
//--------------------------------------------------------------------------
if(bufferFileCache->cacheTreeNode)
{
RAMFileCacheIndex->Remove(bufferFileCache->cacheTreeNode);
bufferFileCache->cacheTreeNode = NULL;
}
When this is entered, the data pointer or the bufferfilecache is NOT
deleted by the tree, right? Also my question is pending, how do I get the
tcachenode of the lastly inserted/updated data??
Best Regards,
SZ
