Metacat

still looking for listObjects problem

more debug for another instance

adding some debug info

fixed bug with upper case comparison

changed getSessionData so that it will respond property to public tokens

MetacatPopulator is now working. It allows you to do a query from one metacat instance, then insert any returned docs into another metacat instance

cleanup of 'fixed' ResourceHandler

tracked down streaming bug. now need to figure out a better way to fix it.

added getValue() to the guid so that it prints the guid and not an object id

added a DataOneLogger for event notifications on the CN. The logger is called DataOneLogger and can be managed in the log4j.properties file

finished getLogRecords. Fixed some date bugs in metacat.

adding getlogrecords to the rest interface.

changed getLogRecords to use new classes for log events

fixed bug in metacat that allowed attribute data to be appended to element data in returnfields

fixed bugs associated with crud access control changes.

implementing getLogRecords

added EventLog statements to all public methods in CrudService in preparation for addin the getLogRecords() method

added better debugging error messages for CN dev errors

added generateMissingSystemMetadata to the ResourceHandler so it is now available via a REST call.

made the test functional so that it checks that missing system metadata will be created.

mostly done with generating systemmetadata from legacy knb docs. need to write a better test and enable this through the ResourceHandler then it will be done.

working on getting systemmetadata creation working for legacy knb objects

working on a function to create dataone system metadata docs for legacy metacat objects that do not have SM.

moved authentication checking out of ResourceHandler and into CrudService

refactored the sessionService to use a correct singleton initialization scheme. Added true authentication to ResourceHandler.

new class to handle system metadata tasks in metacat

listObjects is now working for rest calls as well as crud calls

added some params to the loop that segments the listObjects resultset

allow any nonquote characters in the schemaLocation attribute, otherwise the whole line is matched and this prevents schemaLocation from appearing anywhere but at the end of the line.

finished the crud part of listObjects. need to implement it in the rest interface now.

implementing getObjects in CrudService.

implementing getObjects in CrudService.

implementing getObjects in CrudService.

listObjects is almost working. need to get the result set parsed when returned to CrudService.

setting up the framework for the listObjects api call

changed the detailCode for DataOne exceptions to a string

added getSystemMetadata to ResourceHandler and changed the url format to be meta/guid. added a new servlet reponse handler in the web.xml file to handle the new urls and send them to the RestServlet.

implemented update in ResourceHandler and fixed a bug in CrudService where data files were not handled correctly on update

removed system.outs

amost have update working. still need to get unit test squared away.

added exception testing to the crud test

getting getSystemMetadata to work

refactored XMLSchemaService to not have static methods. made the CrudServiceTest more robust.

removed system.outs

fixed schema location bug. the dataone schemas are now correclty found

removed CrudService dependency on servlet params. CrudService is now a singleton. I'm getting an error from metacat saying it can't find teh systemmetadata schema, even though it is, in fact, registered with metacat. need to identify why this is happening.

refactoring to remove duplicate code

adding a system to track system metadata documents for dataone

Added initial implementation of getSystemMetadata and its associated REST service. Current implementation is returning a hardcoded system metadata document -- need to look up the real document for each guid and return that.

Completed main parts of CrudService.create(). Now the method writes both data and metadata objects along with their system metadata, and handles the mapping between global identifiers and local identifiers. Access control and logging still need to be dealt with to properly authenticate and then log activities.

Modify CrudService to write SystemMetadata to disk with an autogenerated localId and an autogenerated GUID. Validation depends on the DataONE schemas being setup in xml_catalog properly, so still need to check upgrade scripts to be sure these new schemas are added. Still need to handle the metadata document insert, but should be same as system metadata insert.

Added comment about MIME form processing.

Refactored schema service to call doRefresh() in constructor to eliminate code duplication.

Added note on TODO for access bug.

replication of guids now works. tested this for both forced replication and update/insert/delete triggered replication

fixed bug where guid end tag wasn't getting printed

added a method in IdentifierManager to get a guid from a docid and rev. added fields in the documentinfo replication document to pass the guid. now need to handle the guid and insert it into the table if its found

Refactored metacat to use dataone-service-api-0.3.0 jar file, with the new JIBX generated types and serialization. Included JIBX runtime jar in metacat to handle serialization and deserialization of SystemMetadata objects. Removed the old API jar file.

Modifications to support the DataONE service API version 0.1.0. For DataONE, the get() and
create() services are partially complete. Several more functions and checks need to be added to
create() before it is viable. This DataONE support is not complete, and the current support breaks the MetacatRestClientTest for the time being (this client will eventually be removed).

Merge 1.9.2 changes back into the trunk

Modified ResourceHandler to return error codes in XML format for the get() method.

Modifications to metacat rest service to use the new DataONE CrudService for
get() operation. Minor issue with permissions errors propagating up the
stack, but otherwise this is the first implementation of a full DataONE
method.

Modified readFromMetacat() to pass most exceptions up the call stack, which
allows creation of new entry points for calling reads. Still need to
continue factoring out the HTTPServletResponse that is passed in in order to
make entrypoints that are not servlet based possible. Problem now is in...

Refactored putObject method to separate the create() and update() portions in order to match the method signatures needed for DataONE.

Modified ResourceHandler.deleteObject() to take a globally unique id (guid)
as input rather than a metacat-conformant docid. The guid is translated
into a metacat docid which is then used in the handleDelete() call. So now
Metacat supports use of arbitrary identifiers for delete operations, but...

Added support to ResourceHandler to allow the putObject method to use
arbitrary guid strings as input. These strings are examined, and if they
match the Metacat docid format (scope.id.rev), they are used directly. If
the id is a string in another format, a new localId is generated based on...

Fixed bug in getNextRevision() where "error" documents were not being
detected properly before searching for the next identifier.

Added initial support for arbitrary string identifiers in metacat (referred to as a guid). The new identifier table is used to map arbitrary string identifiers to Metacat's current docid format (referred to as the localId). Added a new IdentifierManager class to manage this table, adding new mappings as objects are added to the system. Modified the MetacatTest service to utilize this mapping table to look up a localId from a guid. IdentiferManagerTest is working with these guids now, as is the MetacatTest service get() method, but other parts of the system are unaware of them (e.g., create, update, delete operations are unaware, and no mapping is created when new documents are created). As a consequence, the MetacatRestClientTest is not working (although it also had lots of hardcoded dependencies that need to be fixed as well).

Added copyright, license, and class documentation.

Modified ResourceHandler to change the GET url from /objects to /object to
match the DataONE method name.

Merging in REST interface implementation that was created by Serhan Akin. Main change is
a refactored MetaCatServlet.java class, in which all of the handle* methods were moved
into a separate MetacatHandler.java class. This allows both the standard MetaCatServlet...

Adding missing brackets in else clause. Need to verify with Daigle that this is what he meant.

Move the chunking of large test element data to centralized location in DBSAXNode.writeChildNodeToDB(). Beff up logging

Beef up log messages

Add debug log statements

make sure querygroup is not null before trying to print it.

Get the latest revision from metacat when a modify call docid does not have a revision number.

Send appropriate message when trying to update a docid that was previously deleted.

Reformat file. No code change.

do a quick retry if building path index fails with a SQL error

Make sure buildIndex throws an exception if it has a sqlexception. That way the indexing object will be added to the indexing queue and reprocessed.

Pass the doc xml as a string to docImpl.write and writeRepication. This is so a reader can be create for the parsing and for the write to disk. Also created a db access class for xml query result deletion.

Add comments

make constants final

Fix the bug of http://bugzilla.ecoinformatics.org/show_bug.cgi?id=4645. handleGetRevisionAndDocTypeAction will search both xml_documents and xml_revisions table.
It also changed some constrain in AccessionNumber when user update a document, of which all previous versions are in xml_revisions table.

Add a sleep statement between getting the dtd from source and checking for it via url. Add method names to log output.

Log doc and rev query counts and times. Fix mis-spellings.

Log doc and rev query counts and times. Fix mis-spellings.

remove call to print busy db connections

Add debug to show sql

Fix for Bug #4637 - Metacat Harvester fails to catch some insert and update failures. As per comments in the bug entry, the Metacat Harvester logic has been modified to examine the Metacat client return string to confirm that it contains the substring "<success>" following an insert or update operation. It no longer considers just the absence of an exception as indicative of a successful operation.

log connection warnings only when thresholds are exceeded. Add method names to log output

add method name to log statements

fix spelling of word additional

add method name to log messages and create configured thresholds for warning messages

Change log levels where appropriate and add class/method name to output.

Change warn messages to info

beef up error log messages
