Eric Andersen
f3f9062ecf Things like 'tar -c /tmp/*' and 'tar -cO /tmp/*' where the output 
filename was not explicitly specified were segfaulting.

aff5e2eaef it turs out, there was a nasty tar bug where bb tar would create leading dirs 
with mode 0777 in all cases due to usask issues.  Thanks to Matt Kraai for
noticing and spotting the culprit.  This makes bb tar behave just like GNU
tar once again.

Eric Andersen
cb2a372c9f Revert the patch from Konstantin Boldyshev <konst@linuxassembly.org> to never 
change permissions on existing directories.  This behavior is contrary to SUSv2
and contrary to GNU tar.  Thanks to Matt Kraai for pointing this out.  I should
have been much more careful about accepting such a patch.

af166e7ce0 Logic reversal for last_char_is 2001-04-29 00:50:33 +00:00
Eric Andersen
c1bdffe99b Another nice cleanup from Larry. This adds a new last_char_is() function and 
uses it to avoid possible buffer underruns whn strlen is zero, and avoid the
possible space-hogging inline of strlen() in several cases.
 -Erik
 2001-04-26 15:56:47 +00:00
Eric Andersen
04095e58fb Move messages.c to libbb. Make each string in messages.c be its own .o file. 
This way, we can new get rid of all that tedious #define rubbish we used to
need to enable specific messages.  This way is enormously simpler, and as a
bonus also ends up saving us 96 bytes.

cbe31dace5 It turns out that DODMALLOC was broken when I reorganized busybox.h 
header file usage before the 0.49 release.  To fix it, I had to move
the '#include "busybox.h"' to the end of the list of #include files.

67991cf824 This patch, put together by Manuel Novoa III, is a merge of work 
done by Evin Robertson (bug#1105) and work from Manuel to make
usage messages occupy less space and simplify how usage messages
are displayed.

ed3ef50c23 Fix header file usage -- there were many unnecessary header files included in 
busybox.h which slowed compiles.  I left only what was needed and then fixed up
all the apps to include their own header files.  I also fixed naming for pwd.h
and grp.h functions.  Tested to compile and run with libc5, glibc, and uClibc.

4836fd44f0 Patch from Matt Kraai: 
The following patch makes the -X option to tar behave like GNU,
    which reads one file per line.  It also prevents the last file
    from being appended to the list twice (though that has no
    noticeable impact).

fdd5103348 Merge in two patches from Dave Cinege: 
the first is a cleanup of tar --exclude
    the second changes mount so mtab works more as it should, and

    'mount / -o remount,rw' now works.

3adffb7fc8 readlink(2) does not NULL terminate the buffer it reads in, but tar expected it
