Metacat

Minor logging change.

Add debug logging to delete() to understand why we're getting InsufficientKarmaException.

Since we already have determined access via isAuthorized() and isAdminAuthorized(), act as the Metacat administrator during calls to DocumentImpl.delete() in archive(), passing in null username and group.

restrict getLogRecrods (both MN and CN) to be called only by admin users (the CN)

In setReplicationStatus() and UpdateReplicationMetadata(), don't allow a status state change from COMPLETED to anything other than INVALIDATED. This prevents the completed status from being overwritten due to race conditions.

use metacat.properties to specify the default checksum algorithm to use -- this way it will be easy for us to switch to whatever DataONE decrees.

put(sm) for every pid we have a SM value for so that all members receive the entry event and can save locally.

Throw an exception when NOT allowed, not when allowed =).

ignore partition owner -- always attempt to look up form local store if we were unable to get the SM from the shared map.

do not check if this CN has a "perfect" copy of the SM identifiers -- we need any CN coming online to contribute the records that they have locally so that in the event that all three CNs have a partial view of things they all eventually share each others' SM entries.
