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.

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.

3bf60aa723 If only BB_DPKG was enabled in Config.h, busybox would not build; it'd say: 
dpkg.c:18: #error It looks like you are using libc5, which does not support
  dpkg.c:19: #error tfind().  tfind() is used by busybox dpkg.
  dpkg.c:20: #error Please disable BB_DPKG.  Sorry.
This was fixed by changing the || to an && in the preprocessor.
(We've changed the logic in there too many times.)
Found using multibuild.pl.

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.

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

default tar support code is defined out.

Glenn L McGrath
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.
 2000-09-09 14:50:04 +00:00

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.

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.

------------------------------

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 ?
