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).

ef02f82bcf Paul Mundt, lethal at linux-sh dot org writes:
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

d3612178b7 Patch by Junio C Hamano to workaround a gcc compiler bug.
The construct certain vintages of GCC (the one I have trouble
with is 3.2.3) have trouble with looks like the following:

    static struct st a;
    static struct st *p = &a;
    struct st { int foo; };
    static void init(void) { a.foo = 0; }

The problem disappears if we move the struct declaration up to
let the compiler know the shape of the struct before the first
definition uses it, like this:

    struct st { int foo; }; /* this has been moved up */
    static struct st a;
    static struct st *p = &a;
    static void init(void) { a.foo = 0; }

a3822de23e Patch from Bastian Blank to fix a problem when runing find under ash.
"If the shell is compiled with -DJOBS, this is all fine -- find wasn't
stopped (it was killed), so it correctly uses WTERMSIG instead of WSTOPSIG.
However, if the shell _isn't_ compiled with -DJOBS (which it isn't in d-i),
only WSTOPSIG is used, which extracts the high byte instead of the low
byte from the status code.  Since the status code is 13 (SIGPIPE), "st"
suddenly gets the value 0, which is equivalent to SIGEXIT. Thus, ash prints
out "EXIT" on find's exit."

unless it had #!/bin/sh in the first line

"It correctly locates the script, tries to execute it via execve which
fails. After that it tries to hand it over to /bin/sh which fails too,
since ash

    - neither provides the absolute pathname to /bin/sh
    - nor tries to lookup the script via PATH if called as "sh script"

8e139871fe Patch from Stewart Brodie <stewart.brodie@pace.co.uk> to fix ash:
When alias support is not configured, ash believes that command parameters
that look like dd's "if=/dev/zero" are requests to set a temporary
environment variable whilst dd is running, even though it appears after the
command name.  This is caused by the re-use of the checkalias global variable
to indicate when both alias checking and environment variable checking.  The
failure to reset this flag is due to the reset action being performed only
inside the feature check CHECK_ASH_ALIAS.  Hence ash works as expected when
aliases are configured in, and fails when not.

Example script using 'date' with different settings of TZ:

# TZ=Europe/London
# export TZ
# date
Thu May 30 17:18:49 BST 2002
# TZ=America/New_York date
Thu May 30 12:19:10 EDT 2002
# date
Thu May 30 17:19:12 BST 2002
# date TZ=America/New_York
Thu May 30 12:19:30 EDT 2002    <----- wrong, should be BST time (or error!)
# date
Thu May 30 17:19:35 BST 2002

Attached is a patch against revision 1.52 of ash.c which moves the checks so
that checkalias is updated regardless of whether CONFIG_ASH_ALIAS is set.
With this patch applied, the command shown above which should generate an
error does generate an error.

I have tested this patch with the 'dd' command too and that now works
correctly.
