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).

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.)

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.

a34b48abe5 Upgrade the standalone shell code to use CONFIG_BUSYBOX_EXEC_PATH. 2006-06-14 01:27:01 +00:00
Paul Fox
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.

Here's a follow-up replacement to the patch I sent earlier, this adjusts some

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

$ echo $RANDOM
20057
$ echo $RANDOM
1502
$ export 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."

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

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.

ec07469a3e Patch from Aaron Lehmann <aaronl@vitelus.com>;
This diff does 2 things:

    1) removes an unnecessary function. saves 64 bytes on i386

    2) allows you to disable checking of mail (actually, it's now disabled
    by default). this would be a nice CML1 option, but for now it's a
    #(define|undef) in the C file like the other internal ash options.
    this saves an additional 352 bytes if you leave mail disabled.

just unset the appropriate defines.

c639a35f50 I stupidly forgot one level of pointer indirection in the cmdtxt(), calcsize(),
and copynode() table implementations.  Commit the fix but keep them disabled
until others check them out.  Uncomment "//#define CMDTXT_TABLE",
"//#define CALCSIZE_TABLE", and "//#define COPYNODE_TABLE" to try them out.
Saves over 600 bytes on i386.

74bcd16425 This incorporates Posix math support into ash. The Posix math support
was written by Aaron Lehmann <aaronl@vitelus.com> for busybox.  This
patch makes a few trivial changes to Aaron's code so that it can be
used (in theory) by the other shells as well...

044228d5ec This is vodz' latest patch. Sorry it took so long...
1) ping cleanup (compile fix from this patch already applied).

    3) Fix for functions not declared static in insmod, ash, vi and mount.
    4) a more simple API cmdedit :))
    5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
    6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)

8df319b213 A bit of testing today showed that ASH_BBAPPS_AS_BUILTINS was
totally breaking the shell.  Simple thinge like 'FOO=100' caused
it to segfault.  It turns out that disabling "bltincmd" is a very
bad idea.
