-------------------------------------
Summary: came-ftp - streamDownload=true and stepwise=true for
larger files could cause deadlock
Key: CAMEL-14506
URL: https://issues.apache.org/jira/browse/CAMEL-14506
Project: Camel
Issue Type: Bug
Components: camel-ftp
Affects Versions: 3.1.0
Reporter: Jiri Ondrusek
Assignee: Jiri Ondrusek
If downloading files of size bigger then about 0,5 MB (differs on other
parameters) with option streamDownload=true and stepwise=true (default values),
operation could freeze (on my local environment it freezes with 100%
certainty), because retrieved inputstream has to be closed before calling other
commands .
See
https://commons.apache.org/proper/commons-net/apidocs/org/apache/commons/net/ftp/FTPClient.html#retrieveFileStream(java.lang.String)
{quote}To finalize the file transfer you must call completePendingCommand and
check its return value to verify success. If this is not done, subsequent
commands may behave unexpectedly.{quote}
Problem happens if retrieval of file is immediately followed by change of
directory.
I can imagine fix, which doesn't make change of directory, if is not necessary
and it would be nice to add note to documentation, that streamDownload and
stepWise options together could cause unexpected behavior for larger
filespossibly (possible freeze of component)
