Metacat

-handle NotFound object format when generating system metadata
-improve EML DML for null entity/attribute elements

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

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

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

MNResourceHandler.getObject() was making a call to ObjectFormat.getFmtid() when an object format was null. Check that it is not null before trying getFmtid().

In MNodeService.getCapabilities(), update the properties to match those in metacat.properties. Flesh out the NodeHealth object, adding NodeState, Ping, and Status information. Flesh out the Synchronization object information, but for now, use mock values. TODO: This should be determined from configuration and on-the-fly information.

In MNodeService.getCapabilities(), set the synchronization and replication properties of the node.

In MNodeService.getCapabilities(), set the serviceAvailable for each service supported.

In MNodeService.getCapabilities(), set the serviceVersion for each service supported.

check reservation before create/update

Use D1 properties to set node values, and add the 'WAR VERSION' back into the node name for deployments.

add hasReservation() method (NotImplemented, however)

use objectFormatIdentifier for listObjects()
remove provisional system metadata indicator - Metacat will not implement reserveIdentifier()

use correct log name for the class

consistently construct username/groups for MetacatHandler calls - also consistently call isAuthorized

provisional replicate() implementation -- does not check if the session's subject is "allowed" to do this.
the test also requires 2 servers -- right now it attempts to replicate with itself which will fail because of duplicate IDs

provisional version of getOperationStatistics() -- not clear if we are meant to aggregate by hour or by day

provisional getCapabilities() implementation. Much of the synchronization information and node health is omitted.

simplify the get() method -- no need to use temp files for this operation

implement d1 paging for the log record results

Reverting the resultset order in querySystemMetadata(). Thanks Ben.

Because of the new 'provisional' column, the resultset field order in querySystemMetadata() was out of order. Changed the order to reflect the new table column order.

save systemmetadata when create() is called

allow very minimal system metadata for provisional entries (CN.reserveIdentifier)

Fix a NullPointerException issue when the SubjectList in a Session is null.

Add the missing URL delimiter when building the D1 base service URL.

allow the test to read the OFL docid

check for null docid from access table -- using guid for many system meta rows

use docImpl getBytes() to preserve encoding
no need to catch an exception only to throw it (those I was playing around with looking up the fmt from the d1_common lib if it was not found on the server...but this is redundant with other client code)

remove resolve() test -- not implemented in Metacat

handle data objects (not sci meta) and also set the resulting pid so that create() can succeed

catch exceptions from system meta data query and throw service failure rather than swallowing them with an error msg

handle null values from DB better when querying system metadata

Update getOperationStatistics() to reflect the change in the signature, using ObjectFormatIdentifier instead of ObjectFormat.

Modify monitor() to accept new parameters for getOperationStatisics() (fromDate, toDate) instead of 'period'. Added getDateAsUTC() to parse incoming fromDate and toDate parameter strings.

Fixed problems in IdentifierManager asSystemMetadata(), getSystemMetadata(), and querySystemMetadata() that were using ObjectFormat.toString() rather than ObjectFormat.getFmtid().getValue(). Metacat was storing the string memory pointer rather than the actual format string in the systemmetadata table.

use super class' create() method
use string comparison for assertRelation method

beef up isAuthorized method to check for "public" access rules and also for the rights holder

do not delete if the sysmeta doesn't exist

Use 'synchronization_failed' for the event string in synchronizationFailed(), and add a TODO to use the event enum when the 0.6.3 types are updated.

return all public objects for the search() method [for now]

Changed 'guid' to 'pid' to be in line with the D1 API.

simplify the MN rest servlet mapping to match CN mappings - also streamlined the handler code to share extra path info parsing

add space to error message

route all /d1/cn/* traffic through the CNRestServlet/Handler -- inspect the pathInfo when deciding what action to take and also strip off any extra parts (like pid).
include query() method pass-through to CNodeService

add the old ecogrid query code (still commented out) from the old Rest handler

allow service implementation method to throw exception when guid parameter is null

allow parameters to be omitted in reserveIdentifier handling

implement reserveIdentifier() and check whether the id is reserved when creating records (only allow the create when the Subject creating matches the Subject who reserved it -- currently stored in rightsHolder)

allow for provisional SystemMetadata records (provisional=true)

remove extraneous update() call when create() does the call for us

use monitor() return value when processing response

throw exceptions up the call stack and handle exception reporting/serialization centrally in the handle() method

use logging, not system.out

consolidate session management and parameter preparation in the superclass

throw exceptions up the call stack rather than catching and handling them differently for each possible rest path

consolidate multi part handling in the super class - subclasses need only call the appropriate helper to get access to the needed resources. superclass does some validation to make sure the files are in place in the request

cleaning up the handlers -- removing superclass methods.

refactor to use D1RestServlet and D1ResourceHandler for the D1 rest interface

deprecate the old rest servlet in favor of the new D1-specific (CN/MN) versions

MN rest servlet, handler and mappings

share getSystemMetadata (before refactoring the superclass)

share getSystemMetadata (before refactoring this superclass)

Add placeholder NotImplemented exceptions for getOperationsStatistics() and getCapabilities() in MNodeService.

Implement MNCore.ping() by testing for a successful database connection.

Minor housekeeping - tabs to spaces.

Implement update() in MNodeService. Handle both XML science metadata updates and data object updates. Keep system metadata up to date, and log the update event.

Make isScienceMetadata() protected for access from subclasses.

Add insertSystemMetadata() to D1NodeService, wrap the exception handling from calls to IdentifierManager.

Add updateSystemMetadata() to D1NodeService as a helper method to wrap the exception handling from calls to IdentifierManager.

At Ben's suggestion, add metacatUrl to D1NodeService and make it available to subclasses. Set the metacatUrl in the constructor using SystemUtil rather than all roll your own PropertyService calls. More concise. Also, log the delete event in MNodeService.delete().

add CNRestServlet and mappings for urls in the form:
/d1/cn/*
This extends existing code for CN-specific handling. MN handling will be analogous and is forthcoming

share the deserializer method with subclasses

throw NotAllowed in MNodeService.delete() when isAuthorized() returns false.

Implement the MNStorage.delete() MNodeService. There is debate about what permissions are needed to 'delete' an object (archive it in metacat terms): D1 'WRITE' (metacat 'write') or D1 CHANGE_PERMISSION (metacat 'all'). For now we are using CHANGE_PERMISSION until it is ironed out.

add shared operations for authorization

share tempDir method with subclasses

make RestServlet and ResourceHandler extendible for D1 CN and MN handlers

use session member variable now that we actually have it

isAuthorized: check for nulls in Session subjects, catch any unexpected errors and deny access when in doubt

remove CrudService calls in favor of MNodeService

Remove setParamsFromRequest() from D1NodeService. This was called (previously as CrudService) from ResourceHandler, but will be deprecated in favor of manually creating a param map for each method that needs to pass params on to MetacatHandler.

Implement [MN|CN]Storage.create() in D1NodeService. Since MetacatHandler requires an IP for event logging, we pass in the metacat URL (hold over from CrudService). To do this in the abstract D1NodeService, change the constructors to take metacatUrl as a parameter and get the URL from the metacat properties file in getInstance() of the subclasses. Needs testing.

include URL in resolve() method as well as placeholder for preference

Metacat does not implement CNRegister

Implement CNRead.synchronizationFailed() in MNodeService. Note: The CN URL is not yet available in the SynchronizationFailed exception, but will be once the d1_common_java exception is updated. See https://redmine.dataone.org/issues/1656. Once updated, change this method to explicitly state the CN URL making the call.

Change Metacathandler.read() to be public since it's internal to Metacat, and use read() in D1NodeService after isAuthorized() for the calling Subject from the Session object.

Implement MNRead.listObjects() in MNodeService.

Implement MNRead.describe() in MNodeService.

Implement MNRead.getChecksum() in MNodeService.

Minor formatting changes - tabs to spaces, indents, etc.

Implement [MN|CN]Read.get() in D1NodeService. Added setParamsFromRequest() to pass through parameters from the request object. Since the D1 Authorization API doesn't specify which authentication system a subject belongs to, we don't know if the subject listed is a KNB LDAP DN. isAuthorized() may return true for a mapped identity, but we don't know the DN of the KNB identity per se. This needs to be tested.

-use every Subject in the session (alt Ids and Group membership)
-consolidate to single isAuthorized method

throw exception for unimplemented methods

implement resolve() method

implement assertRelation

implement CNReplication.setReplicationStatus() but with a note about selecting which replica's status should be set (right now it is all)

implement CNReplication.setReplicationPolicy

correction: implementation is CN-specific

implement getChecksum() in the superclass
