["Ruwan Linton (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SYNAPSE-565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740942#action_12740942 ] 

Ruwan Linton commented on SYNAPSE-565:
--------------------------------------

Implemented the locking... I think it has to be configurable and should be able to turn off locking to achieve performance on a deployment where there cannot be a conflict.

Planning to implement it before resolving the issue.

Now before processing any file vfs listener will create a lock and it will be removed just after completing the processing, so no two listeners will process the file at the same time.

Also before starting to upload a file the sender creates a lock file so the VFS listener will not process that file until the file is fully uploaded and the lock is removed. Bot the listener and the sender treats a file item lock as a file with the same name suffixed by the ".lock" sub string.
