Subject [jira] [Created] (SYNAPSE-907) VFSTransportListener locks a folder if a non-matching file is put in to it
Date Sun, 19 Aug 2012 07:35:37 GMT
Amila Maharachchi created SYNAPSE-907:

             Summary: VFSTransportListener locks a folder if a non-matching file is put in
to it
                 Key: SYNAPSE-907
             Project: Synapse
          Issue Type: Bug
          Components: Transports
    Affects Versions: 2.1
         Environment: I have tried this with a ftp/sftp location
            Reporter: Amila Maharachchi
            Priority: Blocker
             Fix For: FUTURE

Create a VFS proxy, provide a file name pattern and a file uri to listen in. Then put a file
with a non-matching file name patter to the mentioned folder. VFSTransportListener locks the
folder without checking whether the file pattern matches and this lock is not released. After
that even if we put a correct file, it cannot be processed due to the lock.

Following code segment is the culprit.


else if (!(!entry.isFileLockingEnabled() || (entry.isFileLockingEnabled()
                                && VFSUtils.acquireLock(fsManager, fileObject))) &&
                                log.isDebugEnabled()) {
                            log.debug("Couldn't get the lock for processing the file : "
                                    + child.getName());

this passes the wrong fileobject to acquire the lock (this should pass child intead of the
fileObject). Even we fix this place, this logic is wrong. We dont need to acquire a lock for
a non-matching file.

I have rectified the logic and I'll provide a patch for this.
