another... This adds bb_xspawn() support, which does vfork/exec. (I don't
know why using a static instead of a local adds ~40 bytes, but using
the local doesn't work...)
Remove -v verbose -V version -q quiet flags
Remove parse_opt_v2();
Rename parse_opt_v3() to parse_xfermode()
Remove if_strcat()
Rearrange code in dump_identity() to reduce size
Modify some strings so that they could be optimized by the compiler
Minor code clean up
Remove unneeded #define <shm.h>
#if BB_BIG_ENDIAN && !defined(__USE_XOPEN)
# define __USE_XOPEN
#endif
Must be before #include <unistd.h> and #include "busybox.h"
(noticed by Bernhard Fischer <rep.nop@aon.at>)
Remove duplicate code in do_time()
- 'function fn_name\n{' breaks on older FreeBSD default shells, so use the more
widely supported 'fn_name () {'. This needs more fixing..
- test for integers ought to use the proper operators
- test for strings ought to use quoting of the strings to be fair to strange
implementations of test(1)
- make sure not to ignore return-codes != 0 from commands; Some shells exit
immediately on this (much like explicitely requesting set -e in e.g. bash)
TODO:
*) Some older shells do not allow a space after the test-condition in an "if"
statement. This doesn't work:
if [ $status -ne 0 ] ; then
as opposed to this:
if [ $status -ne 0 ]; then
or this
if [ $status -ne 0 ]
then
*) strict spacing between commands. In some shells you have to say:
foo ; bar ; baz
The affected shells barf on stuff like ommitting the space, so this doesn't
work:
foo; bar ;baz
*) $() vs. ``
The former isn't really portable as opposed to the latter.
*) fix frong assumption that the testsuite is run from the source-dir.
This is a complete misconception and renders the testsuite completely useless.
That said, i note that IMO a test-harness ought to do it's best to work in
a wide variety of environments, everything else defeats it's purpose.
- flag .depend as .NOTPARALLEL to workaround bug in make-3.80 and make-3.81
Some more details on the second workaround (i.e. kludge):
make-3.80 silently fails, while make-3.81 is at least self-conscious enough to
admit:
include/usage_compressed.h: .config scripts/usage
# Implicit rule search has not been done.
# File does not exist.
# File has not been updated.
# Dependencies commands running (THIS IS A BUG).
# commands to execute (from `/home/cow/src/bb2/Makefile', line 430):
$(Q)$(SHELL) $(top_srcdir)/scripts/usage_compressed "$(top_builddir)/scripts" > $@
I'm giving up on trying to run the rest of the prerequisites of .depend in
parallel and just (try to) indicate that the prerequisites of .depend are
not to be run in parallel.
While this makes `make distclean defconfig;make -j´ work for me, it is not a
real -- longterm -- solution; FIXME
SIGIOT is not defined in any standard i can find and it seems to be
useless (alias for SIGABRT) on linux. i put it in #ifdef but it's
probably best just to remove it and cut down the size a bit.
