Subject [jira] Commented: (NET-376) setListHiddenFiles doesn't work for HFS file system running under zos
Date Thu, 17 Mar 2011 13:26:29 GMT

    [ https://issues.apache.org/jira/browse/NET-376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007914#comment-13007914

Colin Stone commented on NET-376:
---------------------------------

Thanks for the response. 

The code has been implemented as follows:
 
FTPListParseEngine parseEngine = anFTPClient.initiateListParsing(parserType, arguments);
where parserType is UnixFTPEntryParser. 

When I look into the results contained within the parse engine (with no setHidden..) it looks
like the output from a ls -l:
drwxr-xr-x   2 MYUSER1  TSOUSER      608 Mar 16 18:25 test1

By changing the arguments to -al I get 
drwx------      3 MYUSER1  TSOUSER      320 Mar 16 18:25 .
dr-xr-xr-x  14667 NETVIEW  TTY            0 Mar 17 13:53 ..
drwxr-xr-x      2 MYUSER1  TSOUSER      608 Mar 16 18:25 test1 
which is exactly what I wanted.

However when I run the code with no arguments but the setListHiddenFiles set to true on the
FTPClient, I get no files returned and the parse engine seems to have entries corresponding
to:
ftp> ls -a
200 Port request OK.
125 List started OK
.
..
test1

And the parse engine does not interpret them.

As you can see I have already applied a workaround that is acceptable for our requirements,
simply by passing the arguments. It is possible that we have an unusual server FTP setup which
may be missing something configuration wise, so we may just have an extreme edge condition
but worth logging I thought. Sorry I can't help on the publically available front.

> The implementation for setListHiddenFiles is essentially the use of a '-a' parameter
appended to the LIST command. This retrieves the data in a different format to without the
parameter and the parse engine used by initiateListParsing fails to read the lines returned.

> I suggest the parameter should have been '-al' for this scenario
