few new (unfinished) config options, which I intend to make hidden (but
enabled) when CONFIG_NITPICK is disabled. Getting the .config infrastructure
to do that is non-obvious, it seems...
were using "1" as one of the arguments anyway, and as for the rest a multiply
and a push isn't noticeably bigger than pushing two arguments on the stack.
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.)
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.
what to exec. Add -f mode and a brief explanation of how to use it to replace
minicom. Add -l -l mode so you can turn any command into a server. And group
all of netcat's command line options under two CONFIG entries, so if you
disable both it doesn't use getopt at all.
the start of the path. (This should be under the same config option as
the standalone shell, but right now that's buried in the shell menu.)
Also add the ability to specify CONFIG_BUSYBOX_EXEC_PATH with /proc/self/exe
as an overrideable default.
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.
can figure out what header files to include, and override stuff that comes
later. But applets shouldn't include platform.h directly, they should include
busybox.h or libbb.h. Since busybox.h already includes libbb.h, move libbb.h
to the top of busybox.h and platform.h near the top of libbb.h (right after
bbconfig.h, which is something platform.h also needs access to).
While we're at it, move some stuff from busybox.h to libbb.h so we have one
big file to audit/clean up/try to make sense of instead of many.
This needs a second pass to:
+ add bb_daemon(unsigned char no_chdir, unsigned char no_close, const char*flag)
+ eventually globally export argc and argv, so we don't need to pass it to
bb_daemon().
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...)
handle packets out of sequence if some data goes through the buffer and
some doesn't, B) it works on systems that can't handle aligned access,
C) we just have one code path to worry about.
While we're at it, sizeof() and RESERVE_CONFIG_BUFFER() really don't combine
well, which is why md5sum has been reading and processing data 4 bytes at a
time. I suspect that the existence of CONFIG_MD5_SIZE_VS_SPEED to do loop
unrolling and such in the algorithm was an attempt to work around that bug.
