[jira] [Commented] (NET-639) Bug in MVSFTPEntryParser.preParse

["Alexander Eller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NET-639?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16072470#comment-16072470 ] 

Alexander Eller commented on NET-639:
-------------------------------------

After further examination of the pattern, I changed the pattern FILE_LIST_REGEX as a first fix. As - despite the long pattern - only the "recfm" (via pattern) and the "dataset organisation" and "dataset name" (via group) are used, I changed the pattern part concerning the "used" column to be optional (from "\\S+\\s+" to "\\S*\\s+") - now the above line  matches and the line is part of the result.

In MVSFTPEntryParser.java line 64ff

{code:java}
 static final String FILE_LIST_REGEX = "\\S+\\s+" + // volume
                                                                // ignored
            "\\S+\\s+" + // unit - ignored
            "\\S+\\s+" + // access date - ignored
            "\\S+\\s+" + // extents -ignored
            // "\\S+\\s+" replaced ...
            // change respects too large used values and therefor missing delimiter between extents and used
            "\\S*\\s+" + // used - ignored 
            "[FV]\\S*\\s+" + // recfm - must start with F or V
            "\\S+\\s+" + // logical record length -ignored
            "\\S+\\s+" + // block size - ignored
            "(PS|PO|PO-E)\\s+" + // Dataset organisation. Many exist
            // but only support: PS, PO, PO-E
            "(\\S+)\\s*"; // Dataset Name (file name)
{code}
