9213a9e0f2 whitespace cleanup 2006-09-17 16:28:10 +00:00
Denis Vlasenko
6d655be5df removed a lot of trailing \n in bb_msg() calls. It is added 
automatically by function itself.

d921b2ecc0 Remove bb_ prefixes from xfuncs.c (and a few other places), consolidate 
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes...  General cleanup pass.  What I've
been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

b13fee4cbb Since rangecoder is just a bunch of C functions, move it into the one user

to put #include <unistd.h> into libbb.h since it's so darn common...

efae294b15 Fix for an integer overflow bug that could cause a segfault on certain 
pathological archives.

(Unlikely to have security implications, the only way to trigger it basically
wound up doing memset(dbuf,x,2^31) and triggering an immediate segfault.  The
test basically gives us a more polite error message.)

Thanks to Ned Ludd and the Gentoo security guys for finding this.

Hi!

I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.

That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.

I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.

'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.

One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.

4f807a84c5 BusyBox has no business hard coding the number of major and minor bits for a 
dev_t.  This is especially important now that the user space concept of a dev_t
and the kernel concept of a dev_t are divergant.  The only bit of user space
allowed to know the number of major and minor bits is include/sys/sysmacros.h
(i.e. part of libc).  When used with a current C library and a 2.6.x kernel,
this fix should allow BusyBox to support wide device major/minor numbers.

This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and

Erik - please apply.

Authors - please check that I didn't corrupt any meaning.

Package importers - see if any of these changes should be
passed to the upstream authors.

I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.

What is "pretect redefined for test" in cmdedit.c?

Good luck on the 1.00 release!

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.

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).

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.

The tar -x command in busybox does not restore the file mode correctly.

The reason is most probably this code in

       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.

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.

d9d47c3078 Patch from Konstantin Isakov <ikm@pisem.net>: 
In most cases, dirname returns the same argument it was given, so this code
