Subject Problem when trying to reuse version label in transaction
Date Fri, 09 May 2008 13:31:39 GMT

Hi.

There's a problem with reusage of version label. If version (which has label
assigned) is removed inside a transaction, and after this same label is
tried to be assigned to another version (in same transaction), exception is
thrown.

Maven project with test case is here:
http://rpuch.narod.ru/test-reassign-version-label-in-tx.zip
When you run 'mvn test', test using transaction fails, following exception
is thrown:

org.springframework.dao.DataIntegrityViolationException: Invalid version
graph operation; nested exception is javax.jcr.version.VersionException:

Failing test method is:

    public void testReassignVersionLabelInTxThreeTransactions() {
        final String v1 = (String) transactionTemplate.execute(new
TransactionCallback() {
            public Object doInTransaction(TransactionStatus status) {
                return (String) jcrTemplate.execute(new JcrCallback() {
                    public Object doInJcr(Session session) throws
IOException,
                            RepositoryException {
                        Node target =
session.getRootNode().addNode("target3");
                        target.addMixin("mix:versionable");
                        session.save();
                        VersionHistory vh = target.getVersionHistory();
                        Version v1 = target.checkin();
                        vh.addVersionLabel(v1.getName(), "1", false);
                        return v1.getName();
                    }
                });
            }
        });
        final String v2 = (String) transactionTemplate.execute(new
TransactionCallback() {
            public Object doInTransaction(TransactionStatus status) {
                return jcrTemplate.execute(new JcrCallback() {
                    public Object doInJcr(Session session) throws
IOException,
                            RepositoryException {
                        Node target =
session.getRootNode().getNode("target3");
                        VersionHistory vh = target.getVersionHistory();
                        target.checkout();
                        Version v2 = target.checkin();
                        vh.addVersionLabel(v2.getName(), "2", false);
                        return v2.getName();
                    }
                });
            }
        });
        transactionTemplate.execute(new TransactionCallback() {
            public Object doInTransaction(TransactionStatus status) {
                jcrTemplate.execute(new JcrCallback() {
                    public Object doInJcr(Session session) throws
IOException,
                            RepositoryException {
                        Node target =
session.getRootNode().getNode("target3");
                        VersionHistory vh = target.getVersionHistory();
                        target.restore(v1, true);
                        vh.removeVersion(v2);
                        // creating again
                        target.checkout();
                        Version v2 = target.checkin();
                        vh.addVersionLabel(v2.getName(), "2", false); //
this fails
                        return null;
                    }
                });
                return null;
            }
        });
    }

This method creates a node and its first version (which is assigned a label)
in first transaction, then creates second version (which is assigned another
label) in second transaction. Then in the third transaction node is restored
to state stored in first version, second version is removed, new version is
created and assigned a label which was assigned to second version. This last
assignment of label fails.

Please note that same sequence executes successfully if no transactions are
used.
