[jira] Commented: (NET-215) UNIXFTPEntryParser doesn't preserve trailing whitespace in files

["Martin Oberhuber (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NET-215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12591413#action_12591413 ] 

Martin Oberhuber commented on NET-215:
--------------------------------------

It might actually help to make the "name" token more greedy and have it match until the line terminator that would be \\r?\\n but that would require some unit tests to secure the solution...

> From https://bugs.eclipse.org/bugs/show_bug.cgi?id=204740 :
> The Commons Net FTP Entry Parsers do not preserve trailing whitespace on file names. On systems like UNIX that support trailing whitespace, this results in some invalid entries being parsed.
> The bug seems to be in Jakarta Commons Net UnixFTPEntryParser -- in its REGEX,
> the last field ("endtoken") is declared
>     (\\s*.*)
> which means any whitespace followed by at least one non-whitespace character.
> Which is not the case in case of trailing whitespace.
