Subject [jira] [Commented] (NET-566) UnixFTPEntryParser Drops Leading Spaces from File Names
Date Thu, 01 Jan 2015 23:27:13 GMT

    [ https://issues.apache.org/jira/browse/NET-566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14262684#comment-14262684
] 

Sebb commented on NET-566:
--------------------------

Unix file names can contain just about any character except '/'.
They can start with a space, but creating such files is not a good idea as it makes them tricky
to process.
Unix even supports a file name consisting of a single space.

NET already supports MLSD, for example:

http://commons.apache.org/proper/commons-net/javadocs/api-3.3/org/apache/commons/net/ftp/FTPClient.html#mlistDir%28%29

and MLST

http://commons.apache.org/proper/commons-net/javadocs/api-3.3/org/apache/commons/net/ftp/FTPClient.html#mlistFile%28java.lang.String%29

See also

http://commons.apache.org/proper/commons-net/javadocs/api-3.3/org/apache/commons/net/ftp/FTPClient.html#listNames%28%29

which may be useful.

However note that MLSD/MLST are not supported by all ftp servers. Not sure about NLST.

> The {{UnixFTPEntryParser}} [regular expression | http://svn.apache.org/viewvc/commons/proper/net/trunk/src/main/java/org/apache/commons/net/ftp/parser/UnixFTPEntryParser.java?view=markup]
(line 106) consumes all spaces between the timestamp and the file name.
> The {{FTPFile.name}} property ends up getting a value with stripped leading spaces.
