Based on Schily Tools Release 2019-12-05.
AN-2019-11-11:
- libschily: the new functions wcastoi wcastol wcastolb that have been
added with the previous release have been forgotten in the linker map
file.
- star: When using star -copy, the default is now -no-secure-links.
This is what users like since they are copying their own data that
per definition cannot be untrusted external data.
- star: star -diff is now "more smooth" to use, when the archive type
is GNU TAR and the "atime" or "ctime" properties are not present
for a specific file. Before, Jan 1 1970 was the assumed time in
the archive.
- star: star -diff now prints a diff statistics summary.
- star: New version date
AN-2019-12-05:
- include/schily/stdio.h: We no longer define getc_unlocked() on Solaris
in case that it is defined already. This was needed since Oracle
Solaris 11.4 compiles 64 bit by default and made stdio less opaque
than before - this result in the same bahavior as for 32 bit programs.
This means, we no longer need to use tricks to get fast access to
stdio.
Thanks to Rolf Dietze for reporting.
- libschily: the function getargs() and similar (from the option parser
group) fixed a bug that prevented the usability of the official method
to include the char '+' inside option names by quoting the character
in the option name used in the format string.
This bug has been fixed in order to be able to support "star -dump+ ..."
- libshedit: because of the changes in Oracle Solaris 11.4, we need to
#undef FAST_GETC_PUTC in order to avoid to use getc_unlocked().
Thanks to Rolf Dietze for reporting.
- libfind: A new function walksname() has been added to set up the
internals in "struct WALK" for external path names. This feature is
needed to support "star -c list=names -find ...".
- libfind: The functions fetchdir()/dfetchdir(), sortdir(), cmpdir() now
use size_t instead of int for the entry number count and the allocated
size.
This breaks binary compatibility in 64 bit mode for those users only,
that use the interfaces fetchdir()/dfetchdir(), sortdir(), cmpdir().
The only application that currently uses these interfaces is "star".
Simple users of libfind and programs compiled as 32 bit programs
are not affected by the change.
Warning: packetizers need to take care of the changed name of the
shared library file for libfind.
- libfind: Because of the binary incompatible change, we incremented
the major library version number from 3 to 4.
WARNING: This affects only distros that ship 64 bit versions of star
using a shared version of libfind.
Since Solaris defaults to 32 bit programs, this is expected to only
affect Linux distros.
- libstreamar: unicode.c has been changed to make sure that is works even
in case that the "len" parameter is an unsigned.
- libstreamar: to_utf8() from unicode.c has been rewritten to use size_t.
instead of int. Several changes have been introduced in the other
code as well.

- star: The new-volume-script= script is now called at the end of
_every tape_, even at the last one. This now allows to have a script
that automatically renames a standard archive name into numbered
archive names when a tree should be splitted into chunks, e.g. with
this command line:
star -c f=/tmp/v.tar tsize=1G new-volume-script='sh -c \
"mv /tmp/v.tar /tmp/v$(($1-1)).tar" nv' .
you get partial archives named /tmp/v1.tar ... /tmp/vn.tar
Note that this would not work in case that "sh" is the historical
Bourne Shell, e.g. as seen on Solaris 10. This is because
"shell arithmetics" is a feature that was not present in the historical
Bourne Shell.
- star: The man page now mentions that "star cli=tar ..." works as an
alias to "star cli=suntar ...".
- star: The man page now mentions that "star cli=gnutar ..." does not
impement the bugs from the GNU option parser.
- star: Is "star cli=xxx ..." is used, then star now calls
set_progname(xxx) and thus prints error messages labelled with the
command line interface name.
- star: In "pax" command line mode, star now uses -no-fsync as default
in order to behave the same way as the closed source Solaris pax
does.
- star: Star now allows to combine the option list=names with -find
This is useful, whenever a list of filenames is longer than ARG_MAX and
thus cannot be used in the star command line after -find.
Here is an example on how to use the new feature in a mercurial.
based development environment:
(hg status -a; hg status -m; hg status -c) | sed -e 's/^. //' > .hgfiles
star -c list=.hgfiles -find -mtime -100 > /tmp/new.tar
The first command puts all files under control of mercurial into
thw file ".hgfiles" , while omitting the compile results from the
file ".hgfiles".
The second command takes that list and puts only those files into
the archive that have been modified during the past 100 days.
- star: A new option "-dump+" allows to have the "SCHILY.volhdr.hostname"
meta data field filled out even when not making dumps with an
associated dump level. This helps to remember the origin of tar
archives.
- star: unicode.c has been changed to use the same comment as unicode.c
in libstreamar.
- star: unicode.c has been changed to make sure that is works even.
in case that the "len" parameter is an unsigned.
- star: to_utf8() from unicode.c has been rewritten to use size_t.
instead of int. Several changes have been introduced in the other
code as well.
- star: from_utf8() from unicode.c has been rewritten to use size_t.
instead of int. Several changes have been introduced in the other
code as well.
- star: due to the incompatible interface change in libfind (see
above), several changes have been introduced in order to use size_t
instead of int for fetchdir()/dfetchdir(), sortdir(), cmpdir().
This finally permits star to be able to make use of the current POSIX
maximum meta data size for so called "pax" archives (TAR archives
with POSIX.1-2001 meta data enhancements derived from the Solaris 7
concept for tar from 1997). Previous versions of star have been
limited to data no longer than 2 GB (even though the star main code
supports 8 GB file size), this version now supports 8 GB for the.
sum of all meta data for a single file in case a 64 bit binary from
star is used.
- star: the fifo now has a new variant of te function runfifo() that
is used by the new fifo(1) standalone program. See below.
- star: The README now mentions the new "star cli= ..." method and
the fact that star deals with infinite path name length.
