Subject: Star-1.5 source has been released

Please have a look at the German open Source Center BerliOS at www.berlios.de
BerliOS will continue to support free hosting of cryptography projects even
when US laws change and don't allow to host cryptography projects in the USA.

Star is the fastest tar archiver for UNIX

Star has many improvements compared to other tar 
implementations (including gnu tar). See below for a short description
of the highlight of star.

Star is located on:

ftp://ftp.berlios.de/pub/star

Changes since star-1.5.a12:

-	Fixed a typo (R_RDONLY instead of O_RDONLY) in fctldefs.h

-	Support for macppc-netbsd-cc NetBSD on MAC HW.

-	Fixed a minor typo in the star man page.
	Thanks to Eric Raymond

-	'star -n -tpath ...' now only prints the pathnames to allow
	to use the ooutput directly in scripts. If you like the old
	behavior, use 'star -nv ...'

-	Better autoconfiguration for librmt and its users yields in better
	compilation and portability results for OS that do not support the 
	needed internet features for remote tape support.

-	mt.c adopted to the bette autoconf support in librmt

-	New option  errctl= name
          Use the file name as error control  file.   The  reason
          for  using  an error control file is to make star quiet
          about error conditions that are known to be  irrelevant
          on the quality of the archive or restore run. A typical
          reason to use error control  is  to  suppress  warnings
          about  growing log files while doing a backup on a life
          file system.

          The list of error conditions to be ignored may use  one
          or  more  (in  this  case separated by a '|' character)
          identifiers from the list below:

          STAT        Suppress  warnings  that  star  could   not
                      stat(2) a file.

          GETACL      Suppress warnings about files on which star
                      had  problems  to retrieve the ACL informa-
                      tion.

          OPEN        Suppress warnings about  files  that  could
                      not be opened.

          READ        Suppress warnings read errors on files.

          WRITE       Suppress warnings write errors on files.

          READLINK    Suppress  warnings  readlink(2)  errors  on
                      symbolic links.

          GROW        Suppress warnings about files that did grow
                      while they have been archived.

          SHRINK      Suppress  warnings  about  files  that  did
                      shrink while they have been archived.

          MISSLINK    Suppress warnings  about  files  for  which
                      star was unable to archive all hard links.

          NAMETOOLONG Suppress warnings about  files  that  could
                      not  be  archived  because  the name of the
                      file is too long for the archive format.

          FILETOOBIG  Suppress warnings about  files  that  could
                      not  be  archived  because  the size of the
                      file is too big for the archive format.

          SPECIALFILE Suppress warnings about  files  that  could
                      not  be  archived  because the file type is
                      not supported by the archive format.

          SETTIME     Suppress warnings about files on that  star
                      could  not  set the time information during
                      extraction.

          SETMODE     Suppress warnings about files on that  star
                      could  not  set  the  access  modes  during
                      extraction.

          BADACL      Suppress  warnings  access   control   list
                      conversion problems.

          SETACL      Suppress warnings about files on that  star
                      could  not  set  the ACK information during
                      extraction.

     If a specific error condition is  ignored,  then  the  error
     condition  is  not  only  handled  in  a silent way but also
     excluded from the error statistics that are printed  at  the
     end of the star run.

     Be very careful when using error control as you  may  ignore
     any  error  condition.  If you ignore the wrong error condi-
     tions, you may not be able to see real problems anymore.

	A typical error control file line might look this way:

	GROW		*/log/#[^/].log

-------------------------------------------------------------
Star is the fastest known implementation of a tar archiver.
Star is able to make backups with far more than 10MB/s if the
disk and tape drive support such a speed. This is more than
double the speed that ufsdump will get.
In 1996, Ampex got 13.5 MB/s with their DLT tape drive which is a
modified professional digital video tape drive and not related
to Quantum's DLT type drives.
Ufsdump got a maximum speed of about 6MB/s with the same hardware.

Star development started 1982, the first complete implementation has 
been done in 1985. I never did my backups with other tools than star.

Its main advantages over other tar implementations are:

	fifo			- keeps the tape streaming.
				  This gives you faster backups than
				  you can achieve with ufsdump, if the
				  size of the filesystem is > 1 GByte.

	remote tape support	- a fast RMT implementation that has no
				  probems to saturate a 100 Mb/s network.

	accurate sparse files	- star is able to reproduce holes in sparse
				  files accurately if the OS includes 
				  the needed support functions. This is
				  currently true for Solaris-2.3 to
				  Solaris-2.5.1

	pattern matcher		- for a convenient user interface
				  (see manual page for more details).
				  To archive/extract a subset of files.

	sophisticated diff	- user tailorable interface for comparing
				  tar archives against file trees
				  This is one of the most interesting parts
				  of the star implementation.

	no namelen limitation	- Pathnames up to 1024 Bytes may be archived.
				  (The same limitation applies to linknames)
				  This limit may be expanded in future
				  without changing the method to record
				  long names.

	deals with all 3 times	- stores/restores all 3 times of a file
				  (even creation time)
				  With POSIX.1-2001 the times are in nanosecond
				  granularity.
				  Star may reset access time after doing
				  backup. On Solaris this can be done without
				  changing the ctime.

	does not clobber files	- more recent copies on disk will not be 
				  clobbered from tape
				  This may be the main advantage over other
				  tar implementations. This allows
				  automatically repairing of corruptions
				  after a crash & fsck (Check for differences
				  after doing this with the diff option).

	automatic byte swap	- star automatically detects swapped archives
				  and transparently reads them the right way

	automatic format detect	- star automatically detects several common
				  archive formats and adopts to them.
				  Supported archive types are:
				  Old tar, gnu tar, ansi tar, star,
				  POSIX.1-2001 PAX, Sun's Solaris tar.


	automatic compression detect - star automatically detects whether the
				  archive is compressed. If it has been
				  compressed with a compression program that
				  is compatible to decompression with "gzip"
				  or "bzip2", star automatically activates
				  decompression.

	fully ansi compatible	- Star is fully ANSI/Posix 1003.1 compatible.
				  See README.otherbugs for a complete
				  description of bugs found in other tar
				  implementations. Star is the first tar
				  implementation that supports POSIX.1-2001.

	support for ACLs and file flags - star supports Access Control Lists
				  and extended file flags (as found on FreeBSD
				  and Linux). Support to archive and restore
				  other file properties may be easily added.

	support for all inode metadata - star supports to put all inode
				  metadata on the archive. This allows future
				  versions of star to perform true
				  incremental dumps.

Have a look at the manual page, it is included in the distribution.
