8f5b63edea cpio applet, and changes to associated code 2001-06-22 09:22:06 +00:00
Glenn L McGrath
eb1c94078f Reorganise unarchiving functions, more code re-use, only does single pass(no more linked lists), basis for supporting a cpio (and cheaper untar) applet, but cpio applet isnt included in this. 
It effects ar, dpkg-deb applets only

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.

4758368505 Fixed the comments to match the code and renamed the function to a (hopefully) 
more descriptive name, and as per the style guide.

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

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.

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

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 ?

86ab8a32bd A number of additional fixed from Pavel Roskin, note some more bugs in the 
TODO list.  Add Glenn to the Authors list for writing a mini ar for BusyBox,
which is now included.
