tr: stop using globals needlessly.
code: -103 bytes
|
|
size is smaller too (subject to arch differenced I guess)
|
|
|
|
*: s/include "busybox.h"/include "libbb.h"
|
|
This is how it goes. I break stuff by doing useless 'cleanups',
people fix the fallout. :(. Thanks rockeychu!
|
|
|
|
move 'extern environ' up to the location of #includes
|
|
awk: some 'lineno' vars were shorts, made them ints (code got smaller)
awk: rename global t to global ttt. still an awful name, but at least
you can grep for it now.

Put big scary warnings in relevant places.

patch: do not try to delete same file twice
|
|
|
|
('size' happily displays 0 bytes in data and bss,
but in reality sed.o used 180 bytes of it). Oh well.

sed: also make sed -i failure message less cryptic
|
|
|
|
|
|
|
|
|
|
also optimize many strlen() calls.
if (strlen(buf) <= 0) goto vc1 - ??!!
|
|
|
|
(needed for uclibc build, btw). Add testcase for it.
|
|
|
|
|
|
|
|
|
|
no preceding prototype
|
|
|
|
|
|
remaining: shell (rather scary mess in msh.c)
|
|
|
|
|
|
|
|
|
|
but more importantly make code more understandable
|
|
|
|
sed: de-obfuscate piece of code
|
|
|
|
|
|
|
|
|
|
can act quite mysteriously
date: add if(ENABLE_LOCALE_SUPPORT)
|
|
(still has quite a lot of statics etc...).
getopt32-ification.
