Metacat

Don't set the replication status to failed for an object when it is called by a public user. Just throw the NotAuthorized exception. This prevents this node from being de-prioritized because of public calls to the method.

include revisions table in the initial temp table population.
use the "first" creator listed in the EML (either org or person).
use other reasonable default values as needed to fully populate the spreadsheet columns

add columns: publisher and pub_date. include default values for all columns - even data files should have title.
still a few todos but closer.

share the same dbConnection when inserting and then updating SystemMetadata objects in the backing store.
any errors encountered during the update will rollback the entire transaction and the SM record will not exist, even in part.

Do not loadAllKeys() for SystemMetadataMap when Metacat first starts up. hzIdentifiers will be populated with a simple SQL statement rather than the serial loading of every single SystemMetadata object. It will remain in synch using the usual entryXXX() methods as before....

use LRU eviction policy and a small (1000) map size limit to avoid running out of memory because of a large number of system metadata objects

Set the default maximum number of database connections back to 200. After discussion, we've decided it will be better to increase the PostgreSQL limit to 300 and keep Metacat's pool size pretty big.

include pidFilter handling - only matches the complete pid. Issues a warning in the Metacat logs when pidFilter cannot be applied but allows the call to getLogs() to return as though there was no pidFilter given.

use at least one thread on single-processor machines.
