-----------------------------------------
Summary: VFSTransportListener locks a folder if a non-matching
file is put in to it
Key: SYNAPSE-907
URL: https://issues.apache.org/jira/browse/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.
VFSTransportListener#scanFileOrDirectory
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.
