In CNodeService, separate the CN.create() functionality from the MN.create() functionality while still using the superclass to call create(). Deal with Hazelcast locks and setting serial versions only in the CN implementation.

6569 10/31/2011 01:13 PM Chris Jones

Change updateSystemMetadata() to evaluate the incoming system metadata serial version against that found in the hzSystemMetadata map. If they are the same, do the update. If not, throw an InvalidRequest explaining that they need the most current version.

6568 10/29/2011 07:21 PM Chris Jones

Modify CNodeService's registerSystemMetadata() with support for SystemMetadata's serialVersion field. Also, use the hzSystemMetadata map for all system metadata reads using a lock on the pid in order to get the very latest version. This affected isNodeAuthorized(), getChecksum(), and assertRelation(). Since we're using Hazelcast, exceptions are masked as RuntimeException, so throw a ServiceFailure with the underlying message.

6567 10/28/2011 09:46 PM Chris Jones

Modify CNodeService's updateSystemMetadata(), setReplicationStatus(), setReplicationPolicy(), and setOwner() with support for SystemMetadata's serialVersion field. Other methods still pending an update. Use the hzSystemMetadata map for all system metadata reads using a lock on the pid in order to get the very latest version.

6564 10/28/2011 04:05 PM Chris Jones

SystemMetadataManager's functionality is handled by IdentifierManager. Removing it and it's test.

6563 10/28/2011 04:01 PM Chris Jones

MetadataTypeRegister is now replaced by ObjectFormatService. Removing it and it's test.

6561 10/27/2011 05:51 PM ben leinfelder

move the DataONE 1.0.0-SNAPSHOT

6552 10/27/2011 02:13 PM ben leinfelder

Configure and use CertificateManager in order to act as the MN when performing replicate() and getReplica() mthods.

6542 10/20/2011 02:03 PM ben leinfelder

add User-Agent logging to support D1 requirements

6540 10/16/2011 10:47 AM Chris Jones

Add debugging output to MNodeService.

6532 10/12/2011 11:17 AM ben leinfelder

update D1 jars to include recent SubjectList -> SubjectInfo refactoring and the SUBJECT_PUBLIC constant

6530 10/12/2011 10:00 AM ben leinfelder

throw InvalidToken when the Session parameter is null for create()

6528 10/09/2011 02:50 PM Chris Jones

Once a CN calls replicate() on an MN, the MN needs to call getReplica() on the source MN (not get()). Once the bytes are retrieved, the MN must then call back to the CN with setReplicationStatus() to indicate that the replication status is complete. Modify MNodeService to do so.

6525 09/26/2011 10:59 PM ben leinfelder

set date uploaded and date system metadata updated date to current time when calling MN.create() and MN.update()

6522 09/26/2011 12:07 PM ben leinfelder

do not allow system metadata to have obsoletes or obsoletedBy fields when calling the create() method -- these are only allowed for updates so that we do not subvert object versioning by [un]knowingly submitting system metadata that directs one id to another.

6521 09/26/2011 11:59 AM ben leinfelder

set the originating member node on update()

6520 09/26/2011 11:53 AM ben leinfelder

set the originating member node on create()

6518 09/26/2011 11:10 AM ben leinfelder

set sysmeta submitter based on the subject given in the certificate

6512 09/23/2011 02:59 PM Matt Jones

Modified cron schedule to fix the incorrect crontab entry.

6511 09/23/2011 01:44 PM ben leinfelder

do not require ID reservation before create() or update()

6506 09/22/2011 03:30 PM ben leinfelder

check for null session before logging sync failed

6502 09/22/2011 02:01 PM ben leinfelder

correctly implement MN.describe

6496 09/22/2011 10:12 AM ben leinfelder

return null instead of throwing an exception when pid is not found in store

6495 09/22/2011 10:12 AM ben leinfelder

log errors on create() and registerSM

6492 09/22/2011 12:03 AM Matt Jones

Added subject field to getCapabilities() call.

6490 09/21/2011 05:45 PM ben leinfelder

comment out resynch() method until errors are resolved

6489 09/21/2011 05:25 PM ben leinfelder

use default hazelcast config when not configured to use an external one

6484 09/21/2011 04:58 PM Chris Jones

Don't use the hzNodes map yet (as a hazelcast client). Use D1Client instead to get the node list in isNodeAuthorized().

6483 09/21/2011 04:51 PM Chris Jones

For now, remove the hzClient code connecting to the DataONE process cluster to get the hzNodes map. This will be moved into the storage cluster, but use D1Client to get the node list for now.

6481 09/21/2011 10:54 AM rnahf

going back to using IDentifier as the key for the ObjectPAthMap.

6476 09/20/2011 10:20 PM Matt Jones

Fix getCapabilities to properly throw ServiceFailure when properties can not be read, rather than failing with a log message. Fix properties in the Node object to reflect their correct values. Set the sync schedule properly to default to 5 minute intervals. Improve documentation.

6475 09/20/2011 08:52 PM Matt Jones

Reformatted to correct indentation to make class readable.

6474 09/20/2011 02:32 PM ben leinfelder

newer d1 jars -- contains CN.isNodeAuthorized() method

6471 09/20/2011 02:08 PM Matt Jones

Reverting previous @Overrides chanrge from r6470, as that is the desired
behavior under Java 1.6 -- previous versions of Java (e.g., 1.5) will not
comile with this usage of the @Overrides annotation, but the currently
supported version will. So reverting to the 1.6 convention.

6470 09/20/2011 01:36 PM Matt Jones

Removing incorrect @Override annotations that were preventing compilation. The methods marked did not actually override a method in the superclass, so they were not compiling. I think @Overrides was being mistaken for methods that implement an interface but aren't actually in the superclass.

6468 09/20/2011 10:48 AM ben leinfelder

catch runtime exceptions that arise from hazelcast storage errors in the system metadata map

6467 09/20/2011 09:12 AM Chris Jones

Lock the system metadata entry in hzSystemMetadata when calling setReplicationPolicy().

6466 09/20/2011 09:10 AM Chris Jones

Lock the system metadata entry in hzSystemMetadata when calling registerSystemMetadata().

6465 09/20/2011 07:18 AM Chris Jones

Remove references to CNReplicationTask.

6464 09/20/2011 07:17 AM Chris Jones

Remove the CNReplicationTask (for now). We will be using Metacat's ForceReplicationHandler to replicate science metadata across CNs, and may explore the use of a 100% evicted hzScienceMetadata map. Either way, the distributed task design won't be needed. When a dropped CN comes back online, we'll catch it up based on last modified dates for PIDs in the hzSystemMetadata map.

6463 09/20/2011 07:12 AM Chris Jones

Change isNodeAuthorized() to query the hzSystemMetadata map rather than the hzPendingreplicationTasks map. The latter isn't needed for authorization since the ReplicationStatus for each Replica in SystemMetadata lists the status of the replica and can be queried.

6462 09/20/2011 06:42 AM Chris Jones

Add getNodesMap() to return the hzNodes map from the process cluster. Remove getPendingReplicationTasks since that structure is being removed. Add minor documentation.

6459 09/19/2011 03:26 PM ben leinfelder

lookup latest system metadata update date for use in synchronizing CN-CN when an offline nodes comes back online

6458 09/19/2011 12:17 PM rnahf

changed the key type from Identifier to String for ObjectPathMap. (need a Comparable key).

6457 09/19/2011 11:48 AM ben leinfelder

rework this to be MN->MN replication. Should be fleshed out more.

6456 09/19/2011 11:43 AM ben leinfelder

throw RuntimeExceptions when store() methods throw declared exceptions -- we want callers to put() to be alerted if there are errors.

6455 09/19/2011 10:18 AM ben leinfelder

move CNReplicationTask to the hazelcast package

6453 09/16/2011 05:04 PM ben leinfelder

implicit success for setting accessPolicy - trust that the MapStore persists the updated system metadata

6451 09/16/2011 04:42 PM ben leinfelder

check if system metadata exists rather than just the id mapping (before creating the entry)

6449 09/16/2011 03:23 PM ben leinfelder

only "save" to the shared system metadata map - not directly to the table store.

6447 09/16/2011 03:07 PM ben leinfelder

rely on Hazelcast to store the SystemMetadata locally for the node. Entry event listeners store the shared system metadata on their local node when alerted. TODO: remove old replication code that included system metadata xml when replicating scimeta and data

6446 09/16/2011 02:24 PM ben leinfelder

move bulk of the Hazelcast code into HazelcastService from CNodeService so that it is centrall located - easier to manage and configure

6445 09/16/2011 01:13 PM ben leinfelder

verify that the sysmeta checksum value matches the computed checksum value when calling create()

6443 09/16/2011 10:51 AM ben leinfelder

check for null pointers when adding system metadata/creating records during cn.create()

6442 09/16/2011 10:42 AM rnahf

removing unneeded class (never used)

6440 09/15/2011 01:46 PM rnahf

cleaned up mock tests on hzObjectPathMap. split out code for mocking a datastore into MockObjectPathMap.

6437 09/15/2011 12:57 PM ben leinfelder

initialize Hazelcast from the custom configuration when initializing the Metacat service.

6435 09/15/2011 10:40 AM ben leinfelder

handle entryAdded and entryUpdated the same - update the entry if it exists, otherwise create it

6434 09/15/2011 10:38 AM ben leinfelder

handle entryAdded (to hzSystemMetadata) to store sysmeta to local store when it is not already present

6433 09/15/2011 10:37 AM ben leinfelder

make isScienceMetadata() method public/static to be called throughout Metacat

6430 09/14/2011 05:30 PM ben leinfelder

add code to handle new entry when it is not on the local member of the sysmeta cluster

6429 09/14/2011 04:15 PM ben leinfelder

clean up imports - randome quicktime package had been included

6427 09/14/2011 03:17 PM ben leinfelder

comment out processCluster connections that use hzClient until that is finalized

6426 09/14/2011 03:16 PM ben leinfelder

use HashMap, HashSet instead of the Tree* classes that require Identifier objects implement Comparable

6424 09/14/2011 01:52 PM rnahf

configuring hazelcast tests

6421 09/14/2011 11:30 AM ben leinfelder

check for null session before looking at subject

6420 09/14/2011 10:02 AM rnahf

further refactoring and start of unit tests for hazelcast elements

6419 09/13/2011 04:13 PM ben leinfelder

use pending replication task queue to check if node is authorized for replication. moved from old ReplicationService code

6418 09/13/2011 03:44 PM ben leinfelder

save system metadata and/or science metadata and/or ORE objects to the local CN if needed.

6417 09/13/2011 03:29 PM rnahf

small code cleanup - removed unused instantiations of DBUtils.

6416 09/13/2011 02:47 PM rnahf

fixed logic wrt localID and docid. Implemented new method in IdentifierManager to getAllGUIDs from identifier table for implementation of loadAllKeys in ObjectPathMapLoader.

6415 09/13/2011 11:38 AM rnahf

further development of ObjectPathMapLoader.

6414 09/12/2011 02:48 PM rnahf

new class for refreshing the hazelcast map with metacat. Initial commit.

6412 09/12/2011 09:32 AM ben leinfelder

check session != null before checking authorization

6411 09/11/2011 06:41 PM Chris Jones

Add stub methods in CNodeService that implement the Hazelcast EntryListener interface: entryAdded(), entryRemoved(), entryUpdated(), and entryEvicted(). Add a listener to the hzSystemMetadata map so the CNodeService can respond to those events and create appropriate CNReplicationTask objects for distributed execution across the CN cluster. Again, stubs only so far.

6410 09/11/2011 06:27 PM Chris Jones

Minor cleanup - tabs to spaces.

6409 09/11/2011 06:26 PM Chris Jones

Enable CNodeService to access 1) the hzNodes map defined in the DataONE process cluster by becoming a Hazelcast client (hzClient) to that cluster and 2) the hzSystemMetadata map defined in the DataONE storage cluster by becoming a member to that cluster (using direct Hazelcast calls). Added fields for maintaining the DataONE cluster properties.

6407 09/11/2011 06:12 PM Chris Jones

Add in the Hazelcast Id generation namespace and an IdGenerator instance for task ids. Hazelcast will produce cluster-wide unique ids for the "task-ids" namespace, to be used when creating CNreplicationTask objects.

6405 09/11/2011 03:28 PM Chris Jones

Add a CNReplicationTask class that will be submitted to the CN storage cluster when there are changes to the object store involving system metadata, science metadata, and resource maps. When a new entry is added to the hzSystemMetadata map, a new data, science metadata, or resource map was added to the VO, and all CN cluster members need to be updated with the object and it's system metadata. This task is executed on each CN to replicate the information. If the event is an update to an existing system metadata entry, it may only involve a change to system metadata, or may involve a change to science metadata as well. The task will return with the PID of the object replicated, be it a sysmeta, scimeta, or resource object. Locking of the PID will be handled by the task.

6402 09/11/2011 12:20 PM Chris Jones

Catch D1nodeService up to the DataONE 0.6.4 schema where there is no ObjectFormat.isScienceMetadata() method, but rather ObjectFormat.getFormatType() where type is currently one of 'DATA, 'METADATA', or 'RESOURCE'.

6401 09/11/2011 12:12 PM Chris Jones

Modify HazelcastService to read configuration information from an on-disk file (not from a jar file). Added init() to start up the service (was calling doRefresh() before. We still need to decide if this is a refreshable service.

6399 09/08/2011 02:23 PM ben leinfelder

move HazelcastService to D1 package

6397 09/07/2011 05:16 PM ben leinfelder

changes for schema update (d1_common)

6395 09/06/2011 02:33 PM ben leinfelder

added HazelCast MapStore and MapLoader implementation for SystemMetadata

6394 09/06/2011 11:55 AM ben leinfelder

use InvalidRequest when the PID is not found.

6391 09/02/2011 01:57 PM ben leinfelder

use Permission.REPLICATE not EXECUTE

6390 09/02/2011 01:41 PM ben leinfelder

check with the CN if replication is allowed for the object in question for getReplica()

6389 09/02/2011 12:45 PM ben leinfelder

add getReplica() implementation. same as get() but with different logging. seems silly, but maybe I missed something important that distinguishes this method.

6384 08/31/2011 02:36 PM Chris Jones

Update classes to use the DataONE 0.6.4 schema and types. Major changes involve using BigInteger vs long in SystemMetadata.size, and using ObjectFormatIdentifier rather than Object format.

6382 08/10/2011 04:24 PM Chris Jones

Insert system metadata after the data object is inserted.

6378 08/03/2011 10:46 AM ben leinfelder

latest D1 jars - changes include:
updateSystemMetadata() impl for CN
new identifier methods (generate is its own method)
removal of the resourceMap pointer from system metadata

6376 07/29/2011 08:14 AM Chris Jones

Update the d1 common java jar to include the changes to BaseException, and update MNodeService.synchronizationFailed() to use the BaseException.getNodeId() method to report which node the exception came from.

6373 07/28/2011 11:10 AM ben leinfelder

use correct enum method

6371 07/28/2011 10:50 AM ben leinfelder

refactor Constants

6367 07/28/2011 10:10 AM ben leinfelder

remove ServiceTypeUtil - replace with TypeMarshaller

6366 07/27/2011 04:25 PM ben leinfelder

use new "v1" types from DataONE

6362 07/20/2011 03:00 PM ben leinfelder

remove CrudService -- replaced by MNodeService and CNodeService

6358 07/20/2011 11:39 AM ben leinfelder

use the ObjectFormat Id (not toString()) to check against the configured science metadata formats

6354 07/19/2011 08:09 AM Chris Jones

Return the new pid (not the obsoleted pid) on update(), and set the correct system metadata.

6353 07/15/2011 07:11 AM Chris Jones

In D1NodeService.getLogRecords(), don't pass in null start and count params - set them to the defaults (0 and 1000).
