4ef6f647a3 The version checked into the tree is a snapshot of an unifinished applet, and
you just made lots of ">>>>>>> mine" lines show up in my working copy of this.

Please don't do that again.

3476ad651d Second drop. More infrastructure in place, especially for parsing pipelines.
The minimal version got a couple hundred bytes bigger, partly because it's
broken into more functions but mostly because it now dynamically reallocates
and frees everything with no hard-coded limits.  (I thought about making
that optional, but there's a limit to what I can debug and maintain.  It
should still be reasonably NOMMU friendly, the allocations are small and
short lived, and shouldn't contribute noticeably to long-term memory
fragmentation.)

02add9e53a Might as well commit this to have the history. It's not linked in to the
applet list yet (and won't be until it can replace lash, I'm not having five
shells in menuconfig at once), but you can build it with scripts/individual
and mostly this is checked in so I can bloatcheck future versions against it
easily....

This is about as small as a shell can get and still be a shell.

88621d7398 Svn 16007 broke the build under gcc 4.0.3. This fixes up some of the damage
(the e2fsprogs directory is too twisty and evil to easily fix, but I plan
to rewrite it anyway so I'll just bump that up in priority a bit).

been doing for the last couple days.

c9c1a41c58 A couple things that got tangled up in my tree, easier to check in both than
untangle them:

Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the
signal list to that required by posix (they can specify the numbers for
the rest if they really need them).  (This is preparatory cleanup for adding
a timeout applet like Roberto Foglietta wants.)

Export the itoa (added due to Denis Vlasenko, although it's not quite his
preferred implementation) from xfuncs.c so it's actually used, and remove
several other redundant implementations of itoa and utoa() in the tree.

6ab037872f made "test" an ash built-in.
moved the contents of libbb/bb_echo.c back into coreutils/echo.c,
which is a more reasonable place for them than libbb.  this
forces anyone who wants echo and test to be builtin to ash to
also have them available as applets.  their cost is very small,
and the number of people who wouldn't want them as applets is
also very small.

added warning about shell builtins vs. CONFIG_FEATURE_SH_STANDALONE_SHELL,
which conflicts with their use.

thanks to nathanael copa for debugging help.

some string size optimization in test.c may have been lost with
this commit, but this is a good new baseline.

If we exec /proc/self/exe and only fall back to /bin/busybox if /proc isn't

even if busybox isn't installed in /bin on the system in question.

Still won't work in a chroot environment, but it's an improvement.

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.

This patch makes msh handle variable expansion within backticks more

Current behaviour (wrong):

Enter 'help' for a list of built-in commands.

BusyBox v1.00-rc3 (2004.08.26-11:51+0000) Built-in shell (msh)
Enter 'help' for a list of built-in commands.

$ A='`echo hello`'
$ echo $A
`echo hello`
$ echo `echo $A`
`echo hello`
$

The current behaviour (wrong according to standards) was actually my
fault. msh handles backticks by executing a subshell (which makes it
work on MMU-less systems). Executing a subshell makes it hard to only
expand variables once in the parent. Therefore I export all variables
that will be expanded within the backticks and let the subshell handle
the expansion instead.

The bug was found while searching for security leaks in CGI-scripts.
Current behaviour of msh makes it easy to expand backticks by mistake
in $QUERY_STRING. I recommend appling the patch before release of bb
1.00.

A question was posted a month ago by Mark Alamo to see if others had
problems with sourcing subscripts within msh.  We asked his firm to fix the
msh.c bug he described because we didn't have enough time to do it
ourselves.

When msh.c is executing a compound statement and there is a . command to
source another script file, msh.c will not execute the subscript until it's
completed executing the rest of the compound statement.

His example was this:

Echo "Start" ; . ./subA; echo "mid" ; . ./subB ; echo "end"

subA and subB execute AFTER end is printed in reverse order.  The same is
true if the sourced files are inside an if else fi, case esac, or any
compound statement.

Attached is a patch to msh.c.  It fixes the problem.  Cd to the root of your
busybox tree and execute "patch -p1 < msh.c.patch"

Unfortunately, I won't have more time to work on this so I hope that there
aren't any problems!

He,

there is a bug in HUSH's handling of "if" / "elif" commands:

        $  if true
        > then
        > echo 1
        > elif
        > true
        > then
        > echo 2
        > elif
        > true
        > then
        > echo 3
        > else
        > echo 4
        > fi
        1
        2
        3
        $

The same bug exists in all versions of HUSH from BB v0.60.x up to and
including v1.00-pre9. The attached patch fixes this:

        $ if true
        > then
        > echo 1
        > elif
        > true
        > then
        > echo 2
        > elif
        > true
        > then
        > echo 3
        > else
        > echo 4
        > fi
        1
        $



Best regards,

Wolfgang Denk

Just upgraded from 0.6 to 1.00-pre8

Dot command handling handled args correctly (same as bash) in 0.60,
but failed in 1.00:

I fixed this by reverting the dotcmd function back to previous 0.60
instantiation,
please consider using the older version.

Thanks

It looks like latest uClibc defines ARCH_HAS_MMU, but a few busybox files
test UCLIBC_HAS_MMU, resulting in vfork() getting called instead of
fork(), etc.

Patch below.   Only tested for lash.

16767e2377 Patch from vodz to fix the dynamic vars patch, which I should not
have checked in.  Vladimir writes:

Your patch have many problem.
1. You always added + time(). This cannot reset RANDOM=value for debuging
with
replay sequential.
2. Hmm. I examine bash 2.04 source. This pseudorandom generator use low bits
of
counter value. You use high bits. This make bad pseudorandom values after
have
0-value. For example, if + time() do remove, your generator always return 0
after
first generate 0.
3. Memory leak per call. Use ash-unlike unecessary bb_strdup function.
4. Unsupport show last $RANDOM value for "set" and "export" command.
5. Bloat code. Busybox-unlike patch - added unstandart feature as default
hardcode.

Last patch attached.

Erik, why you apply Paul patch with have 5-th point problem? :(

Last patch have ash change xwrite() to fresh libbb/bb_full_write interfase
(haved loop after EINTR).

Here's a follow-up replacement to the patch I sent earlier, this adjusts some
of the semantics of the dynamic variable setting. Namely, dynamic vars can hook
a set handler (which RANDOM uses to adjust the seed). They'll only lose their
dynamic status if they're unset.

I've used the same approach that bash does to come up with the random number,
mostly just for consistency.

For example:

$ echo $RANDOM
13759
$ echo $RANDOM
20057
$ echo $RANDOM
1502
$ export RANDOM=42
$ echo $RANDOM
24179
$ echo $RANDOM
2046
$ unset RANDOM
$ echo $RANDOM

$ export RANDOM=42
$ echo $RANDOM
42
