Version 2.5.1 changed J"org Weule (weule@7b5.de) at 13-AUG-2000
- Thorsten Kranzkowski <dl8bcu@gmx.net> has send me a patch
with a bug fix. Now the listing created by
'mt-dds tell;tar -Rt' created by an unpatched tar can be used.
Version 2.5.0 changed J"org Weule (weule@7b5.de) at 6-AUG-2000
- Roland Wundrig has send me a patch to eliminate quoted
substrings from the index file. In order to alow the user
to use a quoted or unquoted form on the command line,
I coded this feature in a different way.
Version 2.4.21 chanded by J"org Weule (weule@acm.org) at 1998 Aug 5.
- Added Exabyte as a tape vendor.
Version 2.4.20 chanded by J"org Weule (weule@acm.org) at 1998 Jul 28.
- Andrew Ukrainec (ukrainec@infoukes.com) pointed out,
that there is a mistake in the patch of tar inside the
online documentation of the new option. I fixed that.
Version 2.4.19 chanded by Erkki Myllynen (erkki@sweden.hp.com)
- A bug was found inside the tar patch, the calculation
of the thoughtput is fixed now.
Version 2.4.18 chanded by Chris Hanson (cph@martigny.ai.mit.edu)
- Bug fix for dds_index.c to handle LF_LONGNAME records at
the end of tape blocks correctly.
Version 2.4.17 chanded by J"org Weule at 1998 May 25.
- I've deleted the set_density, because HP drives
are operating with variable block sizes well and
othter drives don't support changing the density.
- The blocksize is now the buffer size of the program.
read_ahead is only possible for root and deleted in this
version.
- The calculation of the block numer is changed
Version 2.4.16 chanded by J"org Weule
- scsi_vendor: Added a script to examine the drive vendor.
- on non archive tapes, the blocksize is set to one.
These drives can not handle other block sizes.
Read-ahead is enabled to enhence performance.
- dds_extract.c: Added #define _GNBU_SOURCE for compilation
on new systems like RedHat5.0.
Version 2.4.15 changed by J"org Weule at 1997 Dec 9.
- dds_extract.c: bug-fix, short index lines
- dds_extract.c: support for tar-1.12 verbose listing
Version 2.4.14 changed by J"org Weule at 1997 Nov 30.
- dds_extract.c: bug-fix
- dds_tape.c: to make the program working under HP-UX
thanks to Les.Grant@mitsuibabcock.co.uk
for his patch, sended to me at 1997 Nov 28:
Version 2.4.13 changed by J"org Weule at 1996 Dez 1. :
- Added support for long filenames. Long filenames
are handled with "tar cv ..." and dds2index to create
the index table. "tar xv ..." is not writing an index
dds2tar can handle correct with long file names.
A filename is called long, if it has more than 99 characters.
- Fixed problems matching the index with the header records
of the tape. I made the check more robust.
Version 2.4.12 changed by J"org Weule at 1996 Mar 29. :
- fixed the strncmp calls inside dds2tar.c - thanks to
Goncal Badenes <badenes@imec.be> for the bug fix.
- fixed dds_extract.c --
tar cfv and tar vft are reporting soft _and_ hard links
in a different style. Hard links may not confuse the
header test in dds_extract.
Goncal Badenes <badenes@imec.be> for the bug fix.
- Added a test with an unpatched tar into dds2tar-test.sh.
Version 2.4.11 changed by J"org Weule at 1996 Mar 10. :
- Added a warning: You have to be root to change compression.
- Added dds-dd, a tool to read a tape with unknown block size.
Version 2.4.10 changed by J"org Weule at 1996 Feb 5. :
- Fixed my tar-patch. Sorry for the mistake.
Version 2.4.10 changed by J"org Weule at 1996 Jan 4. :
- Changed the counter --totals with tar-1.11.8-patch to
'long long int' to use very large archives.
Added the calculation of the throuput on --totals.
- Fixed the dds2tar-test.sh script.
- Test for elf compatibility.
Version 2.4.9 changed by J"org Weule at 1995 Feb 4. :
- Added the action filename to mt-dds.
Version 2.4.8 changed by J"org Weule at 1995 Feb 4. :
- Added option 'date <timestammp>' to mt-dds.
- Fixed the code for 'mt-dds ts'
- tar-1.11.2.patch:
Added %T to expand the record-filename with the timestamp.
Version 2.4.7 changed by J"org Weule at 1995 Feb 2. :
- Added a patch to tar (support for sparse file on Linux boxes).
- dds_bsr() inserted to dds_tape.c and used by mt-dds (label).
A small change of ddstool was necessary
Version 2.4.6 changed by J"org Weule at 1995 Jan 29. :
- added the option ts to mt-dds.
- added the option date to mt-dds.
- added teh script 'ddstool' to make some things easier.
- fixed the handling of softlinks in conjunction with
tar index file -- dds2tar ended with FATAL error in
this case.
- added a tool tar2tar.
Version 2.4.5 changed by J"org Weule at 1994 Dez 22. :
- On non HP-DDS devices, teh record number is read from
the device before any block is read.
- Added the option --quick to skip reading of parent directories.
Version 2.4.4 changed by J"org Weule at 1994 Dez 3. :
Version 2.4.3 changed by J"org Weule at 1994 Nov 21. :
- Added a test script with index files to the package.
- Added --body to dds2tar.
- Added label to mt-dds.
Version 2.4.2 changed by J"org Weule at 1994 Nov 21. :
- Fixed some bugs of dds_extract.c.
Version 2.4.1 changed by J"org Weule at 1994 Nov 7. :
- Andreas Bagge was kind enought to report a bug:
Long files (>1MB) are shifting the name field in the tar
listing to the right. dds_extract.c is now able to detect
this.
- I moved the check about the line '-end- ...' to the begining
of the loop inside dds_extract.c.
- Fixed a bug of mt-dds. tell was not working at all.
- Tried to include code to set the right buffer size
in order to allow the change of the buffer of the kernel.
The size of the internal buffer can be set by the -b option
(command line or environment) or is extracted from the
tar record file if possible. The internal buffer should be
large enought to hold one tape block.
- As Andreas Bagge pointed out, a parameter to fnmatch()
serves for matching filenames by giving the directory
entry. The matching is now done similar to tar.
- A workaround lets you create an index of tapes created
with 'tar -b 256 ...' on SunOS. You may have to increase
the default buffer size (ST_BUFFER_BLOCKS) inside the
Makefile to 64 or bigger and the kernel
(/usr/src/linux/drivers/scsi/st.c) in that case. On SunOS I
recommend a block size smaller or equal than 64 (-b option of
tar = 32Kb). You have also to increase the buffer size
of your kernel (/usr/src/linux/drivers/scsi/st.c).
The default buffer size of the kernel is the maximal block
size of tape block which can be read is 32kB.
- The option --body is included.
Version 2.4.0 changed by J"org Weule at 1994 Oct 28. :
- Fnmatch() was found inside clib (gclib). Code deleted.
Version 2.3.9 changed by J"org Weule at 1994 Oct 16. :
- Reading some options from the environment, e.g. -z, -s, -b.
Version 2.3.8 changed by J"org Weule at 1994 Oct 15. :
- Added a check for the header at dds2index.
If it's not a tar header, a skip is performed.
Version 2.3.7 changed by J"org Weule at 1994 Oct 13. :
- change the tar-1.11.2 patch to get the date of archiving
in the listing (bug fix). The date of the label record is
printed correct now while creating the archive.
- New options --z and --no-compress are included.
- The environment variable DDS2TAR should contain the string
--compress to set this option to default.
- The default DEVICE is now /dev/rmt0 like tar.
Version 2.3.6 changed by J"org Weule at 1994 Oct 11. :
- A lot of header files are created. Some source files
are divided into two.
- As Andreas Bagge pointed out, main(argc,argv,envp) is not
ANSI-C code. I deleted envp for that reason, but this still
works.
- I changed the interface to open child processes. Now you
find a nice interface at "zf-cre-open.c". You may open
a pipe to the child process for reading or writing on a
file number of your choice, e.g. 0 or 1 ('creopen()').
(Writing stderr to a child process is not supported.)
The function 'zfopen()' opens a file for reading or writing
with transparent (de)compression. This may also be of interest
for other programs.
Version 2.3.5 changed by J"org Weule at 1994 Oct 11. :
- Added -fwritable-strings to the compiler options
Constant strings are declared const by hand.
Version 2.3.4 changed by J"org Weule at 1994 Oct 10. :
- Inserted a lot of const declarations and fixed a bug
inside an experimental function.
- Added the postscript versions of the manual pages to the
distribution.
Version 2.3.3 changed by J"org Weule at 1994 Oct 10. :
- No access to tape with -l.
- Inserted some lines for security.
If the name of the program is mt-dds, nothing is
written on the disk by the program.
Version 2.3.2 changed by J"org Weule at 1994 Oct 10. :
- bug fix inside dds_extract.c.
Version 2.3.1 changed by J"org Weule at 1994 Oct 9. :
- All header record are checked for the filename.
- New option -l is included to check the index file for the
selected matches. The strings are written to stdout and no
pipeing to tar should be done.
- option --extract included.
Version 2.3.0 changed by J"org Weule at 1994 Oct 9. :
- Added a check inside dds2tar. Now some header records of the
tar files to extract are checked for the expected file name.
dds2tar should stop if you have inserted the wrong tape.
- I inserted a routine to open stdout for a child process or
a file. Andreas Bagge gave me some source to create the
included functions.
- A funktion tar-dds is added to write a tool like tar.
The tool is not ready yet.
- Added background information to the man page of dds2tar.
The lines are based on a text from Andreas Bagge.
Version 2.2.0 changed by J"org Weule:
I have deleted a lot of options to make the software easier to use.
The scan of the index file is very robust.
Hope you agree that dds2tar should be a small tool, simple to
use and with as less parameters as possible. That's why I have
deleted old and obsolete parameters for the costs that you may
have to change some scripts.
Version 2.1.2 Index lines strings with '#' are ignored.
mt-dds can be used to set the tape position of the tape
for the next run of dds2tar. This may be convenient for
shell scripts.
Version 2.1.1 The recfile (-R) can also be an index-file created by dds2index.
The option -t of dds2tar is obsolete.
Help is written to stdout.
Version 2.1.0 made some options obsolete.
Version 2.0.1 is a package with a patch to tar-1.11.2.
Version 2.0.0 is a package of three programs, to make it easier to use.
A lot of options of dds2tar-1.1.3 are included.
So it is easy to switch to this new version.
