46a98dfb13 Reverted my conversion of tar to getopt to ensure tar can 
handle traditional semantics (i.e. 'tar -xvf -' or 'tar xvf'
now both work).

fd3741d712 Remove definition of basename. 
It was defined out so that it would never be seen, and if it was ever seen it wasnt used for anything. It also stops gunzip compiling under the Hurd.

322ae93a5e Fix calls to {m,c,re}alloc so that they use x{m,c,re}alloc instead of 
segfaulting or handling errors the same way themselves.

fca8050f0f Fix .deb unpack and experimental TAR support 
The previous ar.c fialed to recognise one record in .debs

Experimental tar support, this is currently *very* cheap because ar and
tar are functionally similar. It  will need lots of testing so by
default tar support code is defined out.
To test uncomment the line "#define BB_AR_EXPERIMENTAL_UNTAR"

49352adf9c Simplify a few little things, and merge in a patch from 
robotti@metconnect.com so that 'ar -xv' and 'ar -x -v'
both work.

bd7c67136a remove some printf statements i forgot about 2000-09-09 15:04:34 +00:00

e2b345a6d8 Implemented new ar functionality unique to busybox ar (i think), the -R 
option enable a Recursive extraction (or listing) to take place.

i.e. if any files being extracted are themselves ar archives then
busybox ar will extract their contents as well.

e.g. take bar.deb and do (with GNU ar) ar -q foo.deb b.ar
then with busybox ar can do ar -x b.ar data.tar.gz

-R isnt used for anything in GNU ar so i think it should be ok, could
have used long options

This functionality will become (more) usufull with tar, gz support.

437bf72785 Changed getopt so that options can be grouped together, the source 
archive is now assumed to be the first non parameter.

This is how GNU ar behaves.

8324b9f1aa Now supports GNU style long filenames. 
If no filenames are specifed to be (extracted/listed) it will act on
all files in the archive (i dont think the old version did this)

Code is structured to better support upcoming recursive extraction
functionality.

The old code was a bit strange in places, dont know what i was thinking.

with GNU gzip...

06aeb6c417 ar.c now uses a linked list to process headers, uses getopt, new internal function extractAr(srcFD, dstFd, filename) to make it easily accessable to other busybox functions. 
moved copySubFile from ar.c to utilities.c

modified dd.c to use fullWrite

modified copyFile in utilities.c to use copySubFile

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
    also allows mount to use the traditional short form (i.e.
    'mount / -o remount,rw' now works.

While inside tar, I changed it to use getopt...

3adffb7fc8 readlink(2) does not NULL terminate the buffer it reads in, but tar expected it 
to do so.  This caused symlinks stored in tarballs to likely have trailing
crap in the stored symlink named.  Oops.

852ff13fc4 Update to ar.c from Glenn McGrath. His comments follow: 
------------------------------

the attached diff applies to the ar.c i originally submitted

Changes

Preserve dates now works.
Extracted files are set to the uid, gid and mode specified in the
archive.
Checks for valid end of header marker.
Correctly unpacks newer debian files. (has a '\n' character between
entries)
Added more comments.
Cleaned up code.
Added a last modified date to help keep track of versions.


TODO

Common functionality in ar.c are in tar.c should be merged, in
particular getOctal and extractSubFile.

Should all functions that are used by multiple file go in utilities.c ?

0c6a970eb2 * Fixed a small bug that could cause tar to emit warning messages

    of nested directories.  Thanks to Kevin Traas <kevin@netmaster.com>
