Enumeration Type Documentation

◆ ENCCmdFlags

enum ENCCmdFlags

Enumerator
fNoCmdFlags
fNeedsBlobAccess	Command needs access to the blob.
fCanGenerateKey	Command needs to generate blob key if it's empty.
fNeedsStorageCache	Command needs finished database caching to be executed locally.
fDoNotCheckPassword	Do not check access password during command execution.
fDoNotProxyToPeers	Always execute the command locally without proxying to peers.
fUsesPeerSearch	Command needs to search for the latest version of the blob on all servers.
fPeerFindExistsOnly	During the blob search on other servers command needs to know only whether this blob exists or not, i.e. first positive response of existence should finish the search.
fNeedsSpaceAsClient	Command comes from client and needs disk space to execute.
fNeedsSpaceAsPeer	Command comes from other NC server and needs disk space to execute.
fSwapLengthBytes	Byte order should be swapped when reading length of chunks in blob transfer protocol.
fNoReplyOnFinish	Command does not need a confirmation at the end of execution. Usually, all commands need a reply, but storing blob (STOR) may go without (in 'performance' mode)
fReadExactBlobSize	There is exact size of the blob transferred to NetCache.
fSkipBlobEOF	Client will send blob data for the command and won't send EOF marker.
fCopyLogEvent	Command copies sync log event from other server, not creates a new one.
fNeedsAdminClient	Command can be executed only by admin client.
fRunsInStartedSync	Command can be executed only after successful execution of SYNC_START.
fProhibitsSyncAbort	Command should be executed even if server wants to abort the synchronization.
fNeedsLowerPriority	Command should be executed with a lower priority.
fNoBlobVersionCheck	Command shouldn't check the blob version (it doesn't come with the command).
fNoBlobAccessStats	Access information about blob shouldn't be printed at the end of the command.
fSyncCmdSuccessful	Consider synchronization command to be successful even though RequestStatus is not eStatus_OK.
fCursedPUT2Cmd	This is PUT2 command and connection that used PUT2 command.
fComesFromClient	Command comes from client, not from other NC server.
fIsHttp	HTTP-related.
fNeedsBlobList	Command needs access to the blob list.
