This was embarrassing... A build script that was using xargs -I silently
started to ignore -I when we switched over to toybox xargs. The owner of
the script has rewritten it to use the shell read builtin instead, but
it's pretty unhelpful to silently ignore an option that radically
changes how xargs behaves. (The -I behavior sounds sufficiently
different from normal behavior that I'm not sure I've understood, and am
just sending this cleanup rather than actually implementing -I correctly.)

The other xargs implementations in the wild don't seem to count the
space taken by each `char *`. Go for bug compatibility unless future
experience proves that to be a bad idea.

I accidentally added a tab in xargs.c, so as penance I'll clean up all
the tabs.
|
|
Implement -p, -t, and -r.
Add some missing tests.
Move -L and -x back to TODO since they're not implemented and I haven't
yet even understood what they're supposed to do.

that argument (so "t:" fills out TT.t), 2) go ahead and collate arguments of
same type on same line. (Order's guaranteed by C99 either way.)
|
|
Also make -0 and -E mutually exclusive (rather than just ignore -E
with -0).

This avoids "xargs: exec echo: Argument list too long" errors in practice.
find(1) needs to be fixed too, but that's a bit more complicated and a working
xargs provides a workaround.

Test: find /proc | strace -f -e execve ./toybox xargs echo > /dev/null

Adds XVFORK() macro, teaches xpopen_both() to call /proc/self/exe with NULL
argv (and converts cpio -p to use that), adds TOYBOX_FORK guards to some
unconverted commands.

|
Note: vfork(), like fork(), can return -1 if too many processes, and
we should notice and fail loudly.

to greppable TODO annotations in the individual files. (grep -riw TODO)
|
|
WIFEXITED() and WTERMSIG()+127.
|
|
line once. (Tweaked slightly for whitespace and to collate variable declarations.)
|
|
The functions involved were called only once.
|
|
right in years (ubuntu broke its' vim implementation). Remove trailing spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation with new coding style.
The actual code should be the same afterward, this is just cosmetic refactoring.
|
|
FOR_commandname before #including toys.h to trigger it. Rename DEFINE_GLOBALS() to just GLOBALS() (because I could never remember if it was DECLARE_GLOBALS). Convert existing commands to use new infrastructure, and replace optflag constants with FLAG_ macros where appropriate.
