[jira] [Updated] (VFS-472) WebDav runs out of memory when dealing with large files

David Costanzo (Jira)

     [ https://issues.apache.org/jira/browse/VFS-472?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stefan Kordes updated VFS-472:
------------------------------

    Attachment: patch_WebdavFileObject_v2_revision-1459279.diff

We came across a bug in our own solution. Since a buffered output stream is used, not all data is on the piped output stream when closing the piped streams.
We added a latch to wait until all streams are closed.

> When copying or moving large files from any protocol to webdav, an OutOfMemoryException is thrown.
> This is because the WebDavOutputStream uses a ByteArrayOutputStream to store the data before sending.
> We have created a patch for the latest version that uses a PipedOutputStream and a InputStreamRequestEntity to prevent that.
> This issues has been reported before as VFS-47
