Set a default HazelcastInstance after init() is called, and use this instance in getLock() to acquire a lock in the cluster.
no need to cast docInfo entries to String -- they are all strings
set revision history, the create/update dates and the owner/submitter (correctly)
use shared method for looking up "docInfo" map -- both in Metacat replication and in D1 system metadata generation
make default formatting a little bit easier to read
reformat code -- no changes
refactor SystemMetadata creation into separate class from the MetacatHandler -- this will be shared by upgrade code and normal metacat api.
When using ILock.lock(), get a lock on the string value of the Identifier, not the Identifier object itself. Hazelcast locking won't work otherwise.
Use the Hazelcast ILock mechanism to lock the system metadata identifier rather than using IMap.lock(pid).
verify checksum when retrieving replica from another member node.https://redmine.dataone.org/issues/1794
make sure to get/put system metadata to the HZ map instead of using IdentifierManager directlyverified changes for: https://redmine.dataone.org/issues/1999
look-up sych schedule from metacat properties instead of hardcoding themhttps://redmine.dataone.org/issues/1933
when comparing D1 Subject objects, use the equals() method not direct string comparisonhttps://redmine.dataone.org/issues/2050
access nodeList list correctlyhttps://redmine.dataone.org/issues/2049
Use Subject.equals() when comparing DNs rather than CertificateManager.equalsDN(). Don't lock the pid in isNodeAuthorized() to debug for timeout issues. Minor debugging changes.
Minor logging for isNodeAuthorized(), and compare subjects properly. Change this to Subject.compareTo() when it is vetted.
check for authenticated and verified user permissions
throw NotAuthorized when there is no session
Catch RuntimeExceptions thrown by Hazelcast as opposed to general Exceptions to we don't catch exceptions we're trying to throw.
generalize exception handling -- add cause detail
Changes to setReplicationStatus and isNodeAuthorized(), working out minor bugs in replication.
include exception cause when throwing new exception (combine RuntimeException in Exception handling -- they are almst identical)
throw InvalidToken when session is null
correct typo
Send the correct node id (the target node) when calling setReplicationStatus()
check obsoletes and obsoletedBy PIDs when updating objects
delete system metadata when MN.delete() is called.
throw InvalidToken when there is no session (certificate) provided in update() and delete() methods.
Calls to setReplicationStatus() can only be made by a CN or the MN that is the target replica node. Implement this service restriction in CNodeService using CertificateManager's equalsDN() method.
Added stack trace debugging for CNodeService.isNodeAuthorized() for tracking down replication issues.
Use a session object that is set to null when calling CNode.setReplicationStatus()
Add debugging code to MNodeService.getReplica().
Set a new Session object to null, to be overwritten by the CertificateManager session information from the X.509 certificate.
Fix cast to List<Node> in isNodeAuthorized().
upgrade to 1.0.1-SNAPSHOT DataONE jars
Update methods in MNodeService to reflect they modifications of the MN API with regard to exceptions being raised. Largely removed InvalidRequest from a number of methods, and instead threw an appropriate NotFound or ServiceFailure instead.
D1NodeService get(), getSystemMetadata(), and isAuthorized() no longer throw InvalidRequest.
Add in the systemMetadataChanged() method in MNodeService to respond to notifications. Only allow subjects from CNs listed in the node list to make the call. Update the local copy of the system metadata document for the given pid.
Include the serialVersion in the call to CN.setReplicationStatus() after replicating data.
make MNodeServiceTest pass JUnit testing
Update CNodeService to use the serialVersion parameter and compare it to the current serialVersion of the system metadata found in the hzSystemMetadata map. Throw an InvalidRequest exception if they are not equal. This affects updateReplicationMetadata(), setReplicationStatus(), setReplicationPolicy(), setAccessPolicy(), and setOwner().
Add updateReplicationMetadata() to the CN service implementation. This was missing from the API, and likely never called. It fully replaces the given replica item in the list of replicas in system metadata.
getReplica() should log replication events as DataONE Types.Event.replicate (vs 'getreplica')
Minor indentation cleanup.
Modify isAuthorized() to get the most up to date system metadata from the hzSystemMetadata map.
Add a placeholder setAccessPolicy() method in MNodeService that throws NotImplemented since this method is being deprecated. Note: need to confirm that this shouldn't be calling D1Client.getCN().setAccessPolicy().
Update getSystemMetadata() to lock(); get(); unlock() to ensure we have the latest version of system metadata from the hzSystemMetadata map. Remove the setAccessPolicy() method since it is being deprecated in the MNAuthorization API.change insertSystemMetadata() to use a finer grained Date object on insertion. Locking of the pid happens in the subclass prior to the insert.
Add setAccessPolicy() to CNodeService since the CN should only make changes to access policies for objects registered with the D1 system. Increment the serial version after locling and getting the most up to fdate system metadata. Note: CCIT meeting decision says the serial version of the system metadata (during the change) should equal the current serial version, but setAccessPolicy() does not pass in the entire system metadata object, so there's no way to check. For now, increment the latest system metadata from the hzSystemMetadata map.
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.
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.
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.
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.
SystemMetadataManager's functionality is handled by IdentifierManager. Removing it and it's test.
MetadataTypeRegister is now replaced by ObjectFormatService. Removing it and it's test.
move the DataONE 1.0.0-SNAPSHOT
Configure and use CertificateManager in order to act as the MN when performing replicate() and getReplica() mthods.
add User-Agent logging to support D1 requirements
Add debugging output to MNodeService.
update D1 jars to include recent SubjectList -> SubjectInfo refactoring and the SUBJECT_PUBLIC constant
throw InvalidToken when the Session parameter is null for create()https://redmine.dataone.org/issues/1850
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.
set date uploaded and date system metadata updated date to current time when calling MN.create() and MN.update()
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.
set the originating member node on update()
set the originating member node on create()
set sysmeta submitter based on the subject given in the certificate
Modified cron schedule to fix the incorrect crontab entry.
do not require ID reservation before create() or update()
check for null session before logging sync failedhttps://redmine.dataone.org/issues/1798
correctly implement MN.describehttps://redmine.dataone.org/issues/1799
return null instead of throwing an exception when pid is not found in store
log errors on create() and registerSM
Added subject field to getCapabilities() call.
comment out resynch() method until errors are resolved
use default hazelcast config when not configured to use an external one
Don't use the hzNodes map yet (as a hazelcast client). Use D1Client instead to get the node list in isNodeAuthorized().
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.
going back to using IDentifier as the key for the ObjectPAthMap.
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.
Reformatted to correct indentation to make class readable.
newer d1 jars -- contains CN.isNodeAuthorized() method
Reverting previous @Overrides chanrge from r6470, as that is the desiredbehavior under Java 1.6 -- previous versions of Java (e.g., 1.5) will notcomile with this usage of the @Overrides annotation, but the currentlysupported version will. So reverting to the 1.6 convention.
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.
catch runtime exceptions that arise from hazelcast storage errors in the system metadata map
Lock the system metadata entry in hzSystemMetadata when calling setReplicationPolicy().
Lock the system metadata entry in hzSystemMetadata when calling registerSystemMetadata().
Remove references to CNReplicationTask.
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.
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.
Add getNodesMap() to return the hzNodes map from the process cluster. Remove getPendingReplicationTasks since that structure is being removed. Add minor documentation.
lookup latest system metadata update date for use in synchronizing CN-CN when an offline nodes comes back online
changed the key type from Identifier to String for ObjectPathMap. (need a Comparable key).
rework this to be MN->MN replication. Should be fleshed out more.
throw RuntimeExceptions when store() methods throw declared exceptions -- we want callers to put() to be alerted if there are errors.
move CNReplicationTask to the hazelcast package
implicit success for setting accessPolicy - trust that the MapStore persists the updated system metadata
check if system metadata exists rather than just the id mapping (before creating the entry)
only "save" to the shared system metadata map - not directly to the table store.
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
move bulk of the Hazelcast code into HazelcastService from CNodeService so that it is centrall located - easier to manage and configure
