468aea2d88 shells: do not frocibly enable test, echo and kill _applets_,

(makes "true", "false", "basename" REALLY tiny).
getopt32: do not use stdio.

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.)

534374755d Cleaup read() and write() variants, plus a couple of new functions like 
xlseek and fdlength() for the new mkswap.

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.

c2ad4f5d27 Jean Wolter writes: ash uses bsearch to search in the list of built-in commands, therefore the list of built-in commands has to be ordered. Revision 15077 introduced the source built-in and destroyed this order. And now ash doesn't find the shift command anymore. 2006-06-21 18:04:49 +00:00

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

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.
