http://issues.apache.org/bugzilla/show_bug.cgi?id=39109 ------- Additional Comments From [EMAIL PROTECTED] 2006-04-05 19:36 ------- this is my current comments in my working version of MVSFTPEntryParser.java. try to read it and let know if it is understandable. /* * Very brief and imcomplete description of the zOS/MVS-filesystem. * (Note: "zOS" is the operating system on the mainframe, * and is the new name for MVS) * * The filesystem on the mainframe does not have hierarchal structure as * for example the unix filesystem. * For a more comprehensive description, please refer to the IBM manuals * @LINK:www.ibm.... * * Dataset names * ============= * * A dataset name consist of a number of qualifiers separated by '.', * each qualifier can be at most 8 characters, and the total length * of a dataset can be max 44 characters including the dots. * * * Dataset organisation * ==================== * * A dataset represents a piece of storage allocated on one or more disks. * The structure of the storage is described with the field dataset organinsation (DSORG). * There are a number of dataset organisations, but only two are usable for FTP transfer. * * DSORG: * PS: sequential, or flat file * PO: partitioned dataset * PO-E: extended partitioned dataset * * The PS file is just a flat file, as you would find it on the unix * file system. * * The PO and PO-E files, can be compared to a single level directory structure. * A PO file consist of a number of dataset members, or files if you * will. It is possible to CD into the file, and to retrieve the * individual members. * * * Dataset record format * ===================== * * The physical layout of the dataset is described on the dataset itself. * There are a number of record formats (RECFM), but just a few is relavant for * the FTP transfer. * * Any one beginning with either F or V can safely used by FTP transfer. * All others should only be used with great care. * F means a fixed number of records per allocated storage, and V means a variable * number of records. * * * Other notes * =========== * * The file system supports automatically backup and retrieval of datasets. If a * file is backed up, the ftp LIST command will return: * ARCIVE Not Direct Access Device KJ.IOP998.ERROR.PL.UNITTEST * * * Implementation notes * ==================== * * Only datasets that have dsorg PS, PO or PO-E and have recfm * beginning with F or V, is fully parsed. * * The following fields in FTPFile is used: * FTPFile.Rawlisting: Always set. * FTPFile.Type: DIRECTORY_TYPE or FILE_TYPE or UNKNOWN or null * FTPFile.Name: name or null * FTPFile.Timestamp: create time or null * */ /* Format of ZOS/MVS file list: * 0 1 2 3 4 5 6 7 8 9 * Volume Unit Referred Ext Used Recfm Lrecl BlkSz Dsorg Dsname * B10142 3390 2006/03/20 2 31 F 80 80 PS MDI.OKL.WORK * ARCIVE Not Direct Access Device KJ.IOP998.ERROR.PL.UNITTEST * B1N231 3390 2006/03/20 1 15 VB 256 27998 PO PLU * B1N231 3390 2006/03/20 1 15 VB 256 27998 PO-E PLB * */ /* ----------------------------------- * [0] Volume * [1] Unit * [2] Referred * [3] Ext: number of extents * [4] Used * [5] Recfm: Record format * [6] Lrecl: Logical record length * [7] BlkSz: Block size * [8] Dsorg: Dataset organisation.
