This means that you _must_ be connected to start Coda, then go disconnected without ever shutting venus down, right? That would be consistent with the fact that if I start venus, bring the network up, do "ls /coda/realm", and then shut the network down, I have no problems. (I have this vague impression that "ls /coda/realm" may not even be necessary if I gave it a few seconds, maybe the hoard daemon is pinging the server?) I will offer the following behavior as a 'requirement' for coda usability: If one starts venus without network reachability[1], then cached/hoarded files can be accessed. A uid that has previously (in a previous venus invocation, unless an explicit cunlog was done) had permission to access files should continue to be able to access them. In other words, a mapping from uid to coda user/group should persist indefinitely (in RVM) for venus. [1] such as if one's box crashes or is power cycled when away from the net. The basic point is that you should be able to read the cache and make disconnected changes, even if you start up disconnected. Obviously, venus will had to have talked to the servers since it has been re-inited (but this is very different from restarted). This probably leads to a need to either separate the mapping of realm name to IP and realms to cached objects, or to retain the mappings across invocations, perhaps trying to update them periodically. -- Greg Troxel <gdt_at_ir.bbn.com>Received on 2003-09-05 12:54:34
