Karl Wright commented on CONNECTORS-1512:
-----------------------------------------
The patch is against trunk, not 2.10 sources. However, there are no expected
differences between 2.10 and trunk in the files that are included in the patch.
My guess is that patch is having trouble because of differences in line
endings. The sources distribution uses windows conventions, and I expect your
patch utility is not expecting that.
The .patch file is quite short and, if utterly necessary, you should be able to
apply it by hand.

> Project: ManifoldCF
> Issue Type: Bug
> Components: Documentum connector
> Affects Versions: ManifoldCF 2.8.1, ManifoldCF 2.10
> Environment: Documentum 16.4
> Manifold 2.10, using dfc jars 16.4
> Manifold server machine details (although also seen on a Windows-based MF
> 2.8.1):
> {code:java}
> $ hostnamectl
> ...
> Chassis: vm
> Virtualization: kvm
> Operating System: CentOS Linux 7 (Core)
> CPE OS Name: cpe:/o:centos:centos:7
> Kernel: Linux 3.10.0-862.2.3.el7.x86_64

> OpenJDK Runtime Environment (build 1.8.0_171-b10)

> I see an NPE from the Documentum Connector when I re-run a job after deleting
> a file from the Documentum repository using the Documentum Administrator:
> {code:java}
> FATAL 2018-06-29T08:36:54,847 (Worker thread '5') - Error tossed: null
> java.lang.NullPointerException
> at
> org.apache.manifoldcf.crawler.common.DCTM.DocumentumObjectImpl.getContentSize(DocumentumObjectImpl.java:181)
> ~[?:?]
> ...
> at
> org.apache.manifoldcf.crawler.connectors.DCTM.DCTM$ProcessDocumentThread.run(DCTM.java:1399)
> ~[?:?]
> {code}
> The job then appears not to terminate in the Manifold UI. If the job is not
> aborted, the NPE will show again after restarting the Manifold server and
> Documentum Connectors.
> I expect the connectors to handle deletion of source in the repository,
> passing the appropriate status to the output connector, and not failing like
> this.
> Reproduce:
> * Configure Manifold to use Documentum Connectors to talk to a Documentum
> instance
> * Sanity check your configuration by
> ** create a directory in Documentum, D, with two files F, G
> ** create a job in Manifold to take from D and write to the file system in
> directory L
> ** run the job and observe that F, G appear in L
> * delete G from D in Documentum
> ** in Documentum Administrator, right click on G and choose Delete, then OK
> * re-run your job
> * observe that the job doesn't end
> * inspect L
> * observe that F and G are both still present
> * inspect the Manifold logs
> * observe NPE in the logs
>
> In the log file I'll attach, F and G are Book1.xlsx and Book1.xls
