<HTML> <HEADER> <TITLE>Taper version 4 changes</TITLE> </HEADER> <BODY bgproperties="fixed"> <h1><font face="Verdana">Version History</font></h1> <HR> <H1><font face="Verdana"><A NAME="0440">4.4.0</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Change so that there is only one program, taper, which presents the user with a menu so that s/he can select which program to run </font> <LI><font face="Verdana">Allows preferences to be changed within taper. Also allows saving of preferences to preference file or as command line command </font> <LI><font face="Verdana">Made restore a bit more intelligent. If you just want to restore a directory (with no files in it) or devices etc.., then it uses the information in the info file & doesn't have to read anything in from the archive </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">Changed the completion message from "Backup completed successfully" to "Backup completed". Even though the screen reported errors (if any) people were getting confused saying that how could backup have completed successfully if there were errors. The fact is that these errors were non-fatal errors, and therefore, IMHO, backup did complete successfully. But due to popular demand, the message has been changed. Of course, this applies to mkinfo & backup as well. </font> <LI><font face="Verdana">Changed the TAPER.DOC file to reflect better information about SCSIs especially with regard to rewinding & non-rewinding devices. </font> <LI><font face="Verdana">Changes to the documentation to reflect the fact that you don't need to do a 'make dep' anymore </font> <LI><font face="Verdana">Changed the 'update' option in backup to follow the format of other options: ie. on = +u (or --update-on) and off = -u (or --update-off) </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">Problem with the restore tree if files were being backed up individually rather than by directory selection </font> <LI><font face="Verdana">Problem in backup when selecting files. If you selected a file and then selected the directory in which the file resided, the file was backed up twice. Now backup will recognize when files have been selected twice and act accordingly </font> <LI><font face="Verdana">Problem in working out common path (common.c:make_cf) - incorrectly counting number of files in archive </font> <LI><font face="Verdana">Multiple bug problems with the restore tree </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0430">4.3.0</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Restore is now fairly intelligent. That is, it works out which volume files are on and skips to that volume immediately. It also realizes when no more files are to be read from a particular volume and stops reading from that volume </font> <LI><font face="Verdana">Prints the number bytes in archive in both restore & backup </font> <LI><font face="Verdana">Added a -w num option to restore which tells restore to show only those files on volume 'num'. Default value of 0 means show all volumes </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">Changed "Average transfer rate" to "Average backup rate" since it is not an average transfer rate - it takes into account time to advance volumes, rewind tape etc.. Similarly, "Average restore/mkinfo rate" </font> <LI><font face="Verdana">More Makefile tweaks to improve performance </font> <LI><font face="Verdana">Made some improvements to byte counts - still ignores tape headers and volume headers but this really is negligible </font> <LI><font face="Verdana">Rationalised the use of non-rewinding & rewinding tape devices. The non-rewinding tape device is used only to reposition the tape, otherwise the rewinding device is used. </font> <LI><font face="Verdana">Restore prints the volume a file is on and also the position in the archive that the file in </font> <LI><font face="Verdana">Print directory (from restore) also prints the above two pieces of information </font> <LI><font face="Verdana">User interface for restore changed. The files on an archive are now presented in tree form. </font> <LI><font face="Verdana">Made the user interface with regard to restore and multiple volumes a bit clearer and more logical. </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">Wasn't erasing tape correctly in backup and flush_buffers </font> <LI><font face="Verdana">Problem displaying full pathname in top left window of backup if pathname was wider than window </font> <LI><font face="Verdana">In backup, wouldn't enter a link that pointed to a directory </font> <LI><font face="Verdana">Forgot to update volume/tape table in mkinfo </font> <LI><font face="Verdana">Incorrectly printing month file was backed up in restore </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0421">4.2.1</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Checks to see if it can open get tape device status before writing to it. To avoid problems with no tape in drive. </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">Changed the making of .depend in the Makefile. Slightly quicker now </font> <LI><font face="Verdana">Cleaned up the log level 3 messages and make them more detailed </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">None Squashed </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0420">4.2.0</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Added a -u [--update] option in backup. If -u is specified, and a taper backup exists on the backup device, taper will automatically select all files that have been changed since the backup was made. Equivalent preference file option is UPDATE </font> <LI><font face="Verdana">Added a title line showing the name and ID of archive </font> <LI><font face="Verdana">Added another place where preferences can be stored. If a .taper_prefs doesn't exist in /$HOME, then taper now looks in /usr/local/etc (can be changed in common.h). This allows global defaults to be used without having to set environment variables </font> <LI><font face="Verdana">Added option [-j num, --proc-device] for ignoring the /proc filesystem. Program which_device will attempt tell you which device your /proc filesystem is mounted on. See TAPER.DOC for more details </font> <LI><font face="Verdana">New program mktape (to prepare tapes for taper use - only needed if your tape drive writes leading zeroes) and testzero (to see if your tape drive write leading zeroes). See TAPER.DOC for more details </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">Changed the -o [-/+-overwrite option] in restore so that three levels are available: -o 0 = no overwrite (if the file exists, then it is not overwritten); -o 1 = more recent overwrite (if the file on the backup device is more recent than the file on the hard disk, then the hard disk file is overwritten. If the file on the backup device is older than the one on the hard disk, then it is not overwritten); -o 2 = unconditional overwrite (the hard disk file is always overwritten) </font> <LI><font face="Verdana">When a program is finished, prints how many warnings & how many errors were encounterd </font> <LI><font face="Verdana">Changed the word 'Volume' to 'Archive' in backup & restore to make it more consistent with the documentation </font> <LI><font face="Verdana">Changed default color of directory to black on green </font> <LI><font face="Verdana">Changed the handling of long (GNU style) options. Instead of [+/-]-option, you now use --option-on or --option-off. See TAPER.DOC for more details </font> <LI><font face="Verdana">Removed the +/-e (--erase-tape) option. You can use the append option to do the same thing. If you specified --append-off (or -a), and if there is data on the tape, then taper will erase the existing archive and replace it with the new archive. </font> <LI><font face="Verdana">Changed handling of leading zeros problem. If your tape drive writes leading zeroes, define the appropriate variable in the Makefile. When doing backups, you will have to use mktape to prepare tapes for taper use. Taper will not automatically erase tapes for you. If you use an unprepared taper tape, then you will run into problems. See TAPER.DOC for more details </font> <LI><font face="Verdana">Changed handling of directory sizes in sel_restore to make it quicker on large archives. </font> <LI><font face="Verdana">In restore, prints the position in archive of each file </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">Problem with -d option in restore (trying to open status_box) </font> <LI><font face="Verdana">Problem in restore if archive was empty </font> <LI><font face="Verdana">Erase tape when prompting for 2nd, 3rd.. tape of backup </font> <LI><font face="Verdana">Rewind tape after finished writing in multiple tape backups </font> <LI><font face="Verdana">Problem if backup extended by less than one blocksize onto a new tape </font> <LI><font face="Verdana">Problem with calculating how many files to advance when appending to multi-tape archive </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0410">4.1.0</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Added support for multiple tape archives. Required a change to the info file structure therefore, previous taper backups will need to have their info files recreated (easily done with mkinfo - no need to re-backup) </font> <LI><font face="Verdana">Changed Mkinfo to provide a nice screen (user interface change only) </font> <LI><font face="Verdana">Enabled escape mkinfo (of course, if escaped, the info file is incomplete) </font> <LI><font face="Verdana">Logged errors if failed to make a directory in restore </font> <LI><font face="Verdana">Created directory for info files if doesn't exist </font> <LI><font face="Verdana">When reading in the tape header at the beginning of the tape, ignores leading zeroes </font> <LI><font face="Verdana">Added a message box at end of backup/restore/mkinfo saying that everything went OK </font> <LI><font face="Verdana">Added support for long options (GNU style) </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">Internal code change so that the common code between mkinfo & restore is in common.c </font> <LI><font face="Verdana">Changes $ in filenames to \$ to avoid shell expansions when decompressing & compressing files </font> <LI><font face="Verdana">Filename changed to taper-4.1.tar.gz (instead of taper41.tar.gz) to bring it in line with other Linux packages </font> <LI><font face="Verdana">Apart from the tape header, information is written to the tape device in blocks. The size of a block defaults to 28K, but can be changed with the -x option (BLOCK_SIZE in preference file) - the old -x option (or MAX_TRANSFER_SIZE preference option) has been superseeded by this. </font> <LI><font face="Verdana">Changed name of README to TAPER.DOC (it was too big to be a README file) </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">Error in calculating volume count when using mkinfo </font> <LI><font face="Verdana">Error handling soft links in mkinfo </font> <LI><font face="Verdana">Added BOTH option in preference file (was in documentation but never made it into program) </font> <LI><font face="Verdana">The preference file option for location of info files is TAPER_INFO_FILES. The README was incorrect and has been updated </font> <LI><font face="Verdana">Fixed bug that caused extra directories to be created if an absolute path was supplied with -r in restore </font> <LI><font face="Verdana">If backed up an absolute pathname, can now restore using that absolute pathname </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0402">4.0.2</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Added option -x num which allows one to specify the maximum number of bytes to transfer to the tape device in one hit. This is to avoid variable mode SCSI drives returning a EOVERFLOW error </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">Changed the code for parsing arguments so that some of it is modularized in common.c. In preparation for multiple tape archives </font> <LI><font face="Verdana">Internal changes to reading/writing to tape. All calls pass through tape_read & tape_write in common.c. </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">None Squashed </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0401">4.0.1</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">More detailed error messages if couldn't open/read/write to backup & info files etc.. </font> </UL> <font face="Verdana"> <IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER width="26" height="32"> <STRONG>Changes</STRONG> </font> <UL> <LI><font face="Verdana">No Changes </font> </UL> <font face="Verdana"> <IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER width="32" height="32"> <STRONG>Bug Fixes</STRONG> </font> <UL> <LI><font face="Verdana">Fixed -p option not working correctly </font> <LI><font face="Verdana">Changed preferences LOG_FILE & LOG_LEVEL to LOGFILE & LOGLEVEL to match what was in the README file </font> </UL> <font face="Verdana"> </font><HR> <H1><font face="Verdana"><A NAME="0400">4.0.0</A></font></H1> <font face="Verdana"> <IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER width="38" height="39"> <STRONG>New</STRONG> </font> <UL> <LI><font face="Verdana">Command Line Options </font> <TABLE BORDER=1> <TBODY> <TR><TD><font face="Verdana">-?</font></TD><TD><font face="Verdana">on the command line prints help on command line options</font></TD></TR> <TR><TD><font face="Verdana">-v</font></TD><TD><font face="Verdana">prints current version</font></TD></TR> <TR><TD><font face="Verdana">+/-y</font></TD><TD><font face="Verdana">allows the directory to be displayed in alphabetical order or the order in which the files were backed up.<BR> +y means sort in alpha order</font></TD></TR> <TR><TD><font face="Verdana">-/+z</font></TD><TD><font face="Verdana">if on, then confirmation is required when a directory is selected for restore/backup.

Mainly to allow accommodation of feature addition. </font> <LI><font face="Verdana">Changed the handling of stripping pathnames. The full pathname is stored in the information file and on tape. You have the option at restore time of stripping excess pathnames. See README for more details. </font> <LI><font face="Verdana">Played around with restore & backup status boxes a bit.
