to stderr, rather than stdout, so that things like
~ # time bunzip2 -c /tmp/test.bz2 > /dev/null
real 0m 29.44s
user 0m 29.30s
sys 0m 0.12s
operate as expected.
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.
in order to fix the problems with round robin DNS reported
by Andrew Flegg:
http://busybox.net/lists/busybox/2003-October/009579.html
This removes the ipv6 specific xconnect dns lookups. I do
not see why that would need to be special cased for ipv6 as
was done, but that will just have to be tested.
So IPV6 people -- please test this change!

Fixes two bugs:
- END block didn't execute after an exit() call
- huge memory consumption and performance degradation on large input
(now performance is comparable to gawk)
This hides a bug related to the new bunzip code in the tar and dpkg[-deb]
applets.
It will also reduce compile time a little as some unused files wont be
compiled.
Dear list,
during my quest do pack busybox into an RPM, I've fixed a small bug
(missing \n) in dc's usage. And added two additional operations: mod and
exp/power.
Feel free to drop them.
Hi to all,
I'm sorry but I didn't spot this big fat bug until now,
Matteo Croce emailed me about it.
Please apply this patch as the devfsd applet is broken
and works only on a system booted with a standard devfsd
( the test I mostly did :-( ), but if used at boot time
it DOESN'T WORK.
Thanks in advance and please apply
Tito
the busybox menuconfig triggered my "inacceptable number of spelling mistakes"
upper level, so I decided to make a patch ;-)
I also improved some wording to describe some things in a better way.
Many thanks for an incredible piece of software!

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).
Manuel
