File-inbound endpoints may read file several time if polling interval is too short

GoogleCodeExporter commented 9 years ago

This problem affects SFTP-resend service file-inbound endpoints and 
file-inbound endpoints in general.

Problem:

If the file-inbound polling interval is shorter than the time it takes to 
send/stream the file to an outbound endpoint (i.e. the file is still in the 
inbound-directory), then the file will be read again, resulting in duplicates 
for SFTP-outbound (if duplicateHandling="addSeqNo") or overwrites (for example 
in the case of a file-ountbound endpoint).
The re-reading will continue as long as the polling time < transmission time.

This seems to be a known problem with the file-transport, see:
http://www.mulesoft.org/jira/browse/MULE-5374
http://www.mulesoft.org/jira/browse/MULE-5131

The bullet-proof solution seems to be to use the "workDirectory" attribute on 
the file-connector.

Seems fixed for Mule 3.4.0 with:

The solution in Mule 3.4.0 has a problem when fileAge is used for file 
inbounds, see: MULE-6999, MULE-7160.
