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.
Also look at sourcewell.berlios.de, the first Open Source announcement service
that itself is implemented as Open Source project.
***************
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.a13:
- Use symlinks instead of hardlinks for alternate names
of the installed binaries
- Fix several typos in acl_unix.c which prvented the
compilation on Linux systems with ACLs.
The bug has been introduced with star-1.5a13
- Typo in DEFAULTS files fixed
- Better Next STep support:
- Some workarounds for broken unistd.h
- -lkvm removed from Next Step config.
- waitdefs.h fixed for very old BSD based systems (~ 1980)
like Next STep
- fixed typo in fctldefs.h R_RDONLY -> O_RDONLY
- Better Portability for SCO UnixWare
- New platfoms i486, i586, Pentium III, Prntium Pro
- Let strdefs.h also include strings.h for strcasecmp()
- Support for missing struct sockaddr_storage
- Support for froken wait3() (returns wrong timings)
- Changed broken portability Prototype support in libfile
to use 'makefiles / prototype.h' based system
- Changed fileopen() and filereopen() to avoid fdopen()
provlems (does not accept mode string that does not
match fd flags)
- Change autoconf/statdefs.h to support nanosecond support for SCO
UnixWare and FreeBSD
- Call conf/mkdep-sco.sh via sh to be independant from 'x' bit.
- starting to port ACL support to SCO UnixWare (not yet ready)
Revision history (short)

1994 Gnutar and Ustar(Posix.1-1988) handling added
1994 Xstar format (extended Posix.1-1988) defined and introduced
1995 Ported to many platforms
1999 Support for Win32 (Cygwin)
1999 base 256 support to overcome limitation with octal fields

-------------------------------------------------------------
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.
