Julian Reschke commented on JCR-3568:
-------------------------------------
Clarifying: are you using the jackrabbit client components on your server? If I
understand the bug description correctly, that would be the only way how the
server could be affected...
> Property.getBinary().getStream() files in tempDir not removed by
> InputStream.close() nor by Binary.dispose()

> Key: JCR-3568
> URL: https://issues.apache.org/jira/browse/JCR-3568
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-spi-commons, jackrabbit-webdav
> Affects Versions: 2.4, 2.6, 2.7
> Environment: Windows 7 Pro, Java 6.0.39, WebDAV, JCR 2.0
> Reporter: Ulrich Schmidt
> Attachments: jcr3568-r1482639.patch

> I need to inspect the the files stored to the jcr:data-Property in Node
> jcr:content which is a subnode of a nt:file-Node. Access mode is WebDAV using
> JCR 2.0-API.
> Jackrabbit does not drop the temp files created by the command
> Property.getBinary().getStream() by the closing instructions
> InputStream.close() nor Binary.dispose(). I get a RepositoryException "No
> space left on device" when the tempspace becomes full.
> The executed code is;

> Based on a list of repository nodes it retrieves node by node from the
> repository an inspects the temp-directory. After every step it displays the
> number of files in the tempdir, the name and size of the files which are new
> and those which are gone since last inspection.
> This proofs, that for each Property.getBinary().getStream() jackrabbit
> creates six identical files from the jcr:data-property in the tempdir and it
> proofs that these files are not deleted by the instructions:
> InputStream.close();
> Binary.dispose();
> I tested this by installing the latest jackrabbit-jar
> "org.apache.sling.launchpad-6-standalone.jar" from the Sling-Webpage and
> populating the repository with several files.
> Please provide a patch to make sure deletion of the temporary files is done
> in time when issuing the close and/or dispose instruction.
> Please reduce the number of identical temporary files created by the
> Property.getBinary().getStream() instruction. In the test, each of the files
> was 90MB in size. For each of the instructions I need 550MB storage in the
> tempdir.
> Thanks in advance,
> Ulrich
