Glenn L McGrath fea4b446df Important bugfixes from Ian Campbell. 
init_archive_deb_data()
        We want to filter for data.tar.* in the AR file not the TAR
        file, else we get nothing.

all_control_list()
        Make the 'extensions' array of control file names a global so it
        can be used in unpack_package as well. Name the global
        all_control_files. Don't hard code the length of
        all_control_files but instead used sizeof.

unpack_package()
        Only unpack the control files we are interested in (from
        all_control_files). Extract the data.tar.gz into / rather than
        the current directory.

dpkg_main()
        Configure packages in a second pass so all the packages being
        installed are unpacked before configuring.

Some purely cosmetic changes:

header
        update list of differences since two of them are no longer true.
        The .control file is no longer stored as a result of this patch
        -- it was redundant since the info is in status. New packages
        appear to be added to the end of the status file now rather than
        the start.

remove_package()
        Make message printing optional, so we can avoid a redundant
        message when replacing/upgrading a package. When we do print
        stuff then include the version number.

purge_package()
        Print "Purging xxx (yyy) ..." message like the other actions.

configure_package()
        Add "..." to "Setting up" message to be consistent with other
        actions.

Glenn L McGrath 7ffe133864 As we no longer use function pointers for read in common archiving code 
archive_xread can be replaced with bb_full_read, and archive_copy_file
with bb_copyfd*
bb_copyfd is split into two functions bb_copyfd_size and bb_copyfd_eof,
they share a common backend.

Glenn L McGrath 2685724e23 Fix tar -j support 
Use the old fork() method of tar compression support, rather than
read_bz2....
 - (*uncompress)(int in, int out) seems like a more natural interface
for compression code.
 - it might improve performance by seperating the work into one cpu
bound and one io bound process.
 - There is extra code required to do read_[gz|bunzip] since (*uncompress)(int in,
int out) will normally be used by the standalone compression applet.

There have been problems with this method so if you see a "Short read"
error let me know.

compiled.

Hello Rob,

Here's a patch to your bunzip-3.c file.  Nice work btw.

One minor bug fix... checking for error return when read()ing.
Some size/performance optimizations as well.  One instance of
memset() seems unnecssary.  You might want to take a look.

Anyway, on my machine, decompressing linux-2.6.0-test7.tar.bz2
to /dev/null gave the following times:

        bunzip-3.c    bzcat (system)   bunzip-3.c (patched)
real    0m24.420s     0m22.725s        0m20.701s
user    0m23.930s     0m22.170s        0m20.180s
sys     0m0.070s      0m0.080s         0m0.140s

Size of the patched version is comparable (slightly larger or
smaller depending on compiler flags).

Eric Andersen 0d6d88a205 Rob Landley's new micro-bunzip version 3. Rob writes: 
The API for using partial writes, as described in my last message, sucked.

So here's a patch against my last patch that changes things so that
write_bunzip_data calls read_bunzip_data itself behind the scenes whenever
necessary.  So usage is now just start_bunzip(), write_bunzip_data() until it
returns a negative number, and then the cleanup at the end of
uncompressStream.

It adds 32 bytes to the executable, but it should allow the caller (tar) to be
simplified enough to compensate.  Total -Os stripped exe size now 6856 bytes.

Rob

P.S.  I attached the whole C file so you don't have to keep incremental
patches straight if you don't want to. :)

P.S.  In the version I'm banging on now, I've simplified the license to just
LGPL.  I read the OSL a bit more closely and the patent termination clause
would have bit IBM in their counter-suit of SCO if the code in question had
been OSL instead of GPL, and I've decided I just don't want to beta-test
legal code right now.

Glenn L McGrath 91b3d460c7 Fix -C option when creating tar files. 
Need to chdir after the tar file is opened, so make common tar filename
parsing and send the file descriptor rather than filename to
writeTarFile.
Modify the verboseFlag operation to determine wether to display on
stderr or stdout at display time, simpler than doing it in tar_main.

Eric Andersen 2fdba24620 Marc A. Lehmann writes: 
The tar -x command in busybox does not restore the file mode correctly.

The reason is most probably this code in
archival/libunarachive/data_extract_all.c:

       chmod(file_header->name, file_header->mode);
       chown(file_header->name, file_header->uid, file_header->gid);

chown clears the set*id bits (on current versions of linux :). Flipping
the order around fixes the problem.

(tested with 1.00pre3 from cvs).

Glenn L McGrath 87af49f26b If a tar entry is a regualr file ending in a '/' then its really a 
directory.
From http://www.gnu.org/manual/tar/html_node/tar_123.html
REGTYPE
AREGTYPE
    These flags represent a regular file. In order to be compatible with
older versions of tar, a typeflag value of AREGTYPE should be silently
recognized as a regular file. New archives should be created using
REGTYPE. Also, for backward compatibility, tar treats a regular file
whose name ends with a slash as a directory.

bb-tar "cjf" does not create a valid tbz2-archive -- if fact the result is a

    parameter combination "cj" (bb does not have bzip2-compression yet, right?).

Hi, Erik.

    my_getpw(uid/gid) and applets used it have problem:
    if username for uid not found, applets can`t detect it
    (but code pessent). Also "%8ld " format is bad:
    spaces not required (applets have self format
    or spec format (tar applet) and overflow for "id" applet...)
    This problem also pressent in stable version.
    Patch for unstable in attach.

Eric Andersen d9d47c3078 Patch from Konstantin Isakov <ikm@pisem.net>: 
In most cases, dirname returns the same argument it was given, so this code
    works nice, but there's one special case: when the name contains no
    dirname, it returns "." (stored statically in the body of itself), and we
    get a segfault in attempt to free() it.
This patch fixes this problem.

 2002-06-23 22:13:22 +00:00
Aaron Lehmann 8c26fbe537 remove cleanUpAndFail, and replace it with exit(). because that's what 
it does unless srcMode was set, and srcMode is never set.
 2002-06-23 21:56:13 +00:00
Aaron Lehmann 9f92d5f2a2 Major revamp. I've been trying to clean up the code. the bzerror stuff 
still needs major attention (i.e. removal).

Removed references to uninitialized variables like progName,
smallMode, noisy, etc. Remove functions and code for handling "small"
decompression mode, since it is all unreachable. Remove
total_{in,out}* counters - they are never used. Remove panic()
function and assert_h and their uses because they are all for "should
never happen" circumstances. Replace internal malloc/free wrappers
with xmalloc and free. Remove conditional in if(foo)free(foo);
situations. Remove bogus
	if (sizeof(int) != 4) {
		return BZ_CONFIG_ERROR;
	}
(...etc...) code and code for handling BZ_CONFIG_ERROR. Someone should
go through and change the applet to use well-defined types when
appropriate - it expects sizeof(short)==2 && sizeof(int)==4. Until
this commit these were explicitly checked for, and the applet would
exit if these types were not the right size. (I think this is wrong
even as an interim solution.)

With gcc 3.1 reduces size of binary on i386-linux by about 700 bytes.

Lightly tested.

Glenn L McGrath 30f68908ef Another part of Stafan's latest patch, when replacing a pre-existing package set its status correctly. 2001-10-06 02:40:20 +00:00

Glenn L McGrath 24e2833cdf Initial support for for bunzip2.... 
This code could be improvemed by
 1) supporting more options,
 2) Creating a shared crc table with gunzip, or perhaps generated on the fly.
 3) Removing any remaining unneccessary code (e.g. if (noisy))
