Handle SQLExceptions when trying to save system metadata locally.

6893 01/12/2012 01:56 PM Chris Jones

Convert SQLExceptions to RuntimeExceptions for Hazelcast MapStore operations.

6892 01/12/2012 01:54 PM Chris Jones

In IdentifierManager, throw SQLExceptions rather than just logging them, and let them be handled higher up in the stack.

6891 01/12/2012 01:32 PM ben leinfelder

use new endpoint/method:
http://mule1.dataone.org/ArchitectureDocs-current/apis/CN_APIs.html#CNReplication.deleteReplicationMetadata

6890 01/12/2012 12:18 PM ben leinfelder

use PUT /obsoletedBy/{pid} for CNCore.setObsoletedBy per our discussion today

6889 01/12/2012 07:53 AM Chris Jones

Keep the hzIdentifiers set in sync with the Metacat systemmetadata table. If entries are added/updated in the hzSystemMetadata map, make sure the identifier is in the set. If (for some administrative reason) the entry is removed, remove the identifier from the set. This usually doesn't happen.

6888 01/12/2012 07:47 AM Chris Jones

When loading all keys from Metacat into the hzSystemMetadata map, also load identifiers into the hzIdentifiers set if they are not already there. Although entries may be evicted from the map, the list of identifiers will remain. The list will have a fairly small memory footprint since it's just identifiers.

6887 01/12/2012 07:44 AM Chris Jones

Add support for the distributed Set of unique identifiers in the storage cluster called 'hzIdentifiers'. This set is a persistent total list of all identifiers (even when entries in the hzSystemMetadata map are evicted). It reflects the state of the identifiers in the postgresql systemmetadata table, but is distributed across the cluster. Add the getIdentifiers() method, which returns the ISet of identifiers.

6884 01/11/2012 04:42 PM ben leinfelder

include new methods needed for replication (in new d1 jars)
https://redmine.dataone.org/issues/2203

6883 01/11/2012 01:25 PM ben leinfelder

add method: setObsoletedBy (https://redmine.dataone.org/issues/2185)
augement new method: deleteReplicationMetadata

6882 01/11/2012 11:31 AM ben leinfelder

remove method: assertRelation
https://redmine.dataone.org/issues/2158

6881 01/11/2012 11:24 AM ben leinfelder

add method: deleteReplicationMetadata
remove method: assertRelation
update the D1 jars
https://redmine.dataone.org/issues/2187
https://redmine.dataone.org/issues/2158

6880 01/11/2012 10:41 AM ben leinfelder

serialize the Identifier for the systemMetadata being registered
https://redmine.dataone.org/issues/2204

6876 01/10/2012 05:04 PM Chris Jones

Simplify setReplicationStatus() to not call updateReplicationMetadata() if a replica doesn't exist. Just create it and update the system metadata, which we already have a lock for.

6875 01/10/2012 05:03 PM Chris Jones

Minor null checks to avoid NPEs when calling replicate()

6874 01/10/2012 05:01 PM Chris Jones

Don't throw a NotAuthorized exception in isAdminAuthorized() - just return false.

6873 01/10/2012 12:12 PM ben leinfelder

do not download and save remote data resources which are HTML but are not expected to be such (login or info/splash pages before data content).
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5522

6869 01/09/2012 05:08 PM Chris Jones

Update the CN methods to throw a VersionMismatch where the API changed (where serialVersion is a required parameter). These were previously throwing an InvalidRequest exception.
Change the exception handling for calls to Hazelcast to catch a RuntimeException (not Exception) so we don't catch exceptions that we purposefully throw....

6868 01/09/2012 04:59 PM Chris Jones

Use a Logger instead of System.out for SystemMetadataMap.

6867 01/07/2012 06:01 PM Chris Jones

Don't lock() on the map.get() in isNodeAuthorized() (this assumes that the CN has queued the task already). Add more lock/unlock debug statements, and fix setReplicationStatus() - I missed a finally statement to unlock the pid.

6866 01/07/2012 12:39 PM Chris Jones

Modify CNReplication methods setReplicationStatus(), updateReplicationMetadata() and setReplicationPolicy() to allow administrative access from a Coordinating Node by calling isAdminAuthorized().

6865 01/07/2012 12:34 PM Chris Jones

Add isAdminAuthorized() to D1NodeService to check if the operation is being requested from a CN. Consult the NodeList from the CN and test the NodeType of the given node and the X509 certificate Subject. Perhaps we should expand this to also check for service-level access in the future.

6864 01/06/2012 01:51 PM ben leinfelder

store D1 configuration properties in the main backup so that they persist between upgrades.

6863 01/06/2012 12:51 PM Chris Jones

In registerSystemMetadata(), lock the pid prior to calling map.containsKey(pid) since a put to the map could occur between the check and the subsequent put().

6862 01/06/2012 10:45 AM ben leinfelder

update authoritative member node id when we change it (reconfiguration) and when we initially register as a MN with the CN.

6860 01/06/2012 07:40 AM Chris Jones

Correctly deserialize the BaseException subclass in handling calls to setReplicationStatus()

6859 01/06/2012 07:23 AM Chris Jones

Use Lock instead of ILock to be consistent across classes.

6858 01/05/2012 06:32 PM Chris Jones

After reviewing CNodeService and D1NodeService prompted by Robert comparing the Hazelcast locking with the d1_synchronization locking, I've made a number of changes that will prevent locking problems:

1) Multiple methods contained try/catch blocks that would:...

6856 01/05/2012 02:49 PM ben leinfelder

only delete replicated data files (server_location != 1)

6855 01/05/2012 01:37 PM ben leinfelder

use inherited access control from EML for the data file we download from a remote source
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5522

6852 01/05/2012 12:06 PM ben leinfelder

download remote data and save locally when it is referenced by an EML package, then include it in the ORE map.
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5522

6837 01/03/2012 07:32 PM Chris Jones

When the requested count in a call to listObjects() is 0, return an empty object list, not a full one. Fixes https://redmine.dataone.org/issues/2122

6836 01/03/2012 07:30 PM Chris Jones

Minor formatting for querySystemMetadata().

6830 01/03/2012 03:56 PM ben leinfelder

exapnd permissions on the exisiting access rule not on the permission being checked. (hierarchical permissions)

6826 01/03/2012 10:56 AM ben leinfelder

upgrade routine to purge empty replicated data files so that they can be re-replicated
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5536

6822 12/22/2011 11:51 AM Chris Jones

Make sure the local id isn't null when we try to get the object from the local instance.

6821 12/22/2011 11:16 AM Chris Jones

Simplify the error handling, and throw the exception once the CN is updated with the new status.

6820 12/22/2011 11:13 AM Chris Jones

Set the replica status to failed (not invalidated) when we get exceptions trying to read the object bytes. Not much of a difference, but only the CN, in theory, is supposed to be able to set the invalidated status.

6819 12/22/2011 11:07 AM Chris Jones

Set the replication status to invalidated when we have a localId, but getting the object bytes fails for any reason.

6818 12/22/2011 10:51 AM Chris Jones

Only call super.create() if there's no localId found on the MN (ie a replica is there from an out of band process).

6817 12/22/2011 10:40 AM Chris Jones

Get the object inputstream from the local metacat instance using MetacatHandler.get() rather than MN.getReplica() so we don't throw an InvalidToken exception when passing in a null Session. The D1Client object is never used for this local call.

6816 12/22/2011 09:24 AM ben leinfelder

interpret permissions as hierarchical
https://redmine.dataone.org/issues/2150

6814 12/21/2011 01:00 PM ben leinfelder

remove flag for independent system metadata replication -- these entries are replicated along with the data/metadata objects or via hazelcast when the actual object is not on the server.

6808 12/20/2011 11:25 AM ben leinfelder

process the current revision, not the latest!
use direct object/system metadata insertion for ORE maps.

6807 12/20/2011 11:21 AM ben leinfelder

allow other Metacat process (system metadata and ORE generation) to directly insert objects and system metadata without having to go through the MN/CN methods.

6806 12/20/2011 11:19 AM ben leinfelder

sort the docids so that "old" revisions are processed before newer ones

6805 12/19/2011 01:07 PM ben leinfelder

only attempt to unlock a lock if it was created (in the finally block)

6803 12/16/2011 04:24 PM ben leinfelder

new jars with many changes -- including new CN methods: ping, describe, listChecksumAlgorithm. Removed MN.setAccessPolicy. Refactored CN.setOwner() to CN.setRightsHolder().

6802 12/16/2011 12:21 PM ben leinfelder

refresh the SystemMetadata entry for EML and referenced data files when parsing EML access rules -- this ensures our in-memory system metadata map is up to date WRT the DB entries.

6800 12/16/2011 11:00 AM ben leinfelder

add revision history to the generated ORE objects -- we use the revision history of the EML package as a basis because the each ORE revision mirrors the revision of the EML package.
Add a placeholder for checking if an equivalent ORE map exists in the DataONE infrastructure - this will be a call to CN.search() that looks at the solr index for OREs based on the EML package ID.

6799 12/16/2011 09:56 AM Chris Jones

Update the parameter names expected for listObjects() to reflect the MN API changes in the architecture docs.

6798 12/16/2011 09:44 AM Chris Jones

Change the query semantics such that we implement the MN.listObjects() where the lower datetime bound is inclusive (greater than or equal to" and the upper datetime bound in exclusive (less than). This allows easier paging in client applications.

6795 12/16/2011 07:42 AM Chris Jones

In the call to MNReplication.replicate(), call back to CNReplication.setReplicationStatus() and set the status to failed when we get local exceptions, exceptions from the source MN when calling getReplica(). Send back an exception with a description when setting the status. Add a private setReplicationStatus() method to refactor these calls out.

6794 12/16/2011 07:36 AM Chris Jones

Modify CNresourceHandler.setReplicationStatus() to use the new API signature, including the failure BaseException that is parsed out of the MMP as a file section. Log the exception message. Since this is an asynchronous call, ReplicationManager won't see a failed status, but the MNAuditTask eventually will.

6793 12/16/2011 07:32 AM Chris Jones

Add collectReplicationStatus() to CNResourcHandler to return the BaseException or it's subclass, if any, provided in the the call to setReplicationStatus. The exception will be reported on the CN.

6792 12/16/2011 07:29 AM Chris Jones

Change setReplicationStatus() to drop serialVersion and report the failure exception message in the CN log.

6787 12/15/2011 01:29 PM ben leinfelder

set SystemMetadata.archived=true on MN.delete
There is ongoing discussion on what the exact behavior should be here, but this mimics Metacat's delete-as-archive action.
http://redmine.dataone.org/issues/882

6786 12/14/2011 08:48 AM Chris Jones

In MNodeService.replicate(), check to see if we have a replica (via an out of band channel) before we call sourceMN.getReplica().

6783 12/13/2011 05:06 PM ben leinfelder

only create guid->docid mapping during metadata replication if it does not already exist
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5520

6782 12/13/2011 04:50 PM ben leinfelder

do not treat access change as an update -- it should not attempt to retrieve the contents of the object
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5520

6780 12/13/2011 04:18 PM ben leinfelder

only create guid->docid mapping during data replication if it does not already exist
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5520

6779 12/13/2011 03:30 PM ben leinfelder

remove xml_acccess.docid reference (oops)
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5560

6777 12/13/2011 12:22 PM ben leinfelder

updated D1 API -- removed Permission.REPLICATE and associated parameters

6775 12/13/2011 11:34 AM ben leinfelder

process system metadata before access rules (access control is now driven by GUID so the mapping needs to be there)

6774 12/13/2011 11:06 AM Jing Tao

Change the key of query result cache. The key now has the real search value.

6773 12/13/2011 10:58 AM ben leinfelder

include SerialVersion in describe response
https://redmine.dataone.org/issues/2135
NOTE: d1 jars should be replaced once all schema changes are finalized and the generate d1_common code is committed to svn

6766 12/12/2011 10:50 AM ben leinfelder

include 'archived' system metadata element in backing DB store

6757 12/09/2011 09:05 AM Chris Jones

If a member node cannot be found in the node list matching the targetNodeSubject given in isNodeAuthorized(), throw a ServiceFailure exception.

6756 12/09/2011 08:04 AM Chris Jones

Minor reformatting for readability.

6754 12/08/2011 01:51 PM ben leinfelder

update with latest d1_common/d1_lib (includes latest schema changes)

6752 12/08/2011 01:12 PM ben leinfelder

only handle 100 (consecutive!) docId generations per millisecond, otherwise the generated docid part is bigger than Long.MAX_VALUE and Metacat cannot fully handle that.

6750 12/08/2011 11:22 AM ben leinfelder

check previous revision when attempting to update access control with EML 2.0.x docs
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5560

6749 12/08/2011 10:17 AM ben leinfelder

remove old access rules for a data object when they are being updated by rules contained in an EML document. Now the OnlineDataAccessTest EML 2.1.0 tests pass.
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5560

6748 12/07/2011 05:31 PM ben leinfelder

construct the proper previousDocId when checking for update permission

6747 12/07/2011 05:05 PM ben leinfelder

for now, look up SystemMetadata directly from the table otherwise we won't have the latest access information. Need to refresh the in-memory copy everytime we edit the access policy via Metacat (includes EML parser)

6746 12/07/2011 05:04 PM ben leinfelder

check previous revision for permissions to update (includes data described by EML)

6745 12/07/2011 05:02 PM ben leinfelder

use correct "rev" column in xml_revisions table

6744 12/07/2011 12:18 PM ben leinfelder

refactor Metacat access handling to be on a per-revision basis so that it more closely aligns with the DataONE approach
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5560

6743 12/07/2011 12:16 PM Chris Jones

To avoid id generation conflicts happening at the same millisecond, append a 5 character random string to the end of the docid.

6740 12/06/2011 03:03 PM ben leinfelder

retry: add node name in the correct order for predicate navigation
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5561

6738 12/06/2011 02:50 PM ben leinfelder

add node name in the correct order for predicate navigation
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5561

6734 12/02/2011 05:32 PM ben leinfelder

handle queries with predicates correctly.
when docids are used in the return field look up, we need to make sure they are included in the values in the correct order for their corresponding parameter place holders (?)

6732 12/02/2011 11:27 AM ben leinfelder

close prepared statement only if not null
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5562

6728 12/01/2011 03:38 PM Jing Tao

Use accessblock in setaccess method. So user can grant/revoke public readable access.

6727 12/01/2011 01:30 PM ben leinfelder

ensure that the revision list is ordered ascending in case someone changes the sql query without realizing that it matters...

6726 12/01/2011 01:21 PM ben leinfelder

set the byte size of the ORE map before adding it

6725 12/01/2011 01:12 PM ben leinfelder

set/update the obsoletes/obsoletedBy fields in system metadata so that we always have a complete revision history for each object.
Note: ORE maps do not have revision history...yet(?)

6724 12/01/2011 01:10 PM ben leinfelder

order the revision list, ascending.

6723 12/01/2011 11:57 AM ben leinfelder

removing unused class -- can't find a reference to it and it's causing compilation errors for me.

6722 12/01/2011 11:53 AM ben leinfelder

for "all" permission, return a list of READ, WRITE, CHANGE_PERMISSION

6721 11/30/2011 05:31 PM ben leinfelder

generating ORE maps and creating/updating system metadata now. There are some Permission conversion issues to be worked out yet

6720 11/30/2011 05:25 PM ben leinfelder

look up access policy by guid or local id
TODO: resolve the Metacat/EML "all" permission as it relates to DataONE (there is only READ, WRITE, CHANGE_PERMISSION). for now I am using CHANGE_PERMISSION when it is a Metacat "all"

6719 11/30/2011 05:23 PM ben leinfelder

make exception/error reporting clearer -- was getting lock messages when perhaps that was not the correct exception.

6718 11/30/2011 05:22 PM ben leinfelder

look up all docids is now a static method (ORE/SystemMetadata generation)

6717 11/30/2011 02:22 PM Chris Jones

Add log statements for each call to ILock.unlock() for debugging.

6714 11/29/2011 03:43 PM ben leinfelder

evict the HazelCast SystemMetadata entry if we update the access control rules via Metacat's legacy API, otherwise stale SystemMetadata stays in memory instead of being looked up from the backing table store.

6713 11/29/2011 03:41 PM ben leinfelder

optionally include ORE generation/insertion into Metacat when generating SystemMetadata
https://redmine.dataone.org/issues/2056

optionally include ORE generation/insertion into Metacat when generating SystemMetadata
https://redmine.dataone.org/issues/2056

6711 11/29/2011 01:44 PM Chris Jones

Set a default HazelcastInstance after init() is called, and use this instance in getLock() to acquire a lock in the cluster.

6710 11/29/2011 01:41 PM ben leinfelder

no need to cast docInfo entries to String -- they are all strings
