// CTrkSvrSvc::MoveNotify
|
|
//
|
|
// Handle a move notify request from trkwks.
|
|
//
|
|
// This routine is complicated by DS replication. It is possible that two trksvr
|
|
// services may modify the same entry in the IDT within a replication window.
|
|
// The only way to prevent this is to design such that only the designated DC
|
|
// modifies entries. For this MoveNotify routine, that would mean that an
|
|
// entry would be added for each notification, the designated DC would then
|
|
// shorten the base entry, and delete this new one. That's not friendly
|
|
// to the DS, however, because deleted objects must continue to be stored
|
|
// for an extended period of time.
|
|
//
|
|
// Consequently, if this notify modifies an existing entry, this routine
|
|
// performs a modify rather than an add. For example, if a file is
|
|
// moved from A to B to C, and this routine is being called for that
|
|
// second move, it would just modify the existing entry from A->B to
|
|
// A->C.
|
|
//
|
|
// The risk here is that another DC will attempt to modify this entry
|
|
// within the same replication window. We don't have to worry though
|
|
// about another DC doing a notify; trkwks only sends to one DC.
|
|
// There are two cases to worry about. One is the case where another DC
|
|
// marks an entry to be deleted. If that happens after we do the modify
|
|
// here, then there is no problem; the entry is no longer needed anyway.
|
|
// If that happens before we do our modify here, then the delete flag
|
|
// will be lost. This case is rare, and the unnecessary entry won't
|
|
// stay in the table forever; it will be garbage collected.
|
|
//
|
|
// The other case of potential conflict is if an entry has not
|
|
// yet been counted; in this case the designated DC might count
|
|
// it and clear the uncounted flag. If our modify causes that
|
|
// flag to be uncleared, then the move table count would be corrupted.
|
|
// So if the uncounted flag is set, we do an add rather than a modify.
