Several parameters common on Linux are missing on macOS.

Be consistent about upper versus lower case. (Upper seems to have the
majority, so I went with that, though I'm happy to provide the opposite
patch as long as we're consistent!)
Be consistent about using \t. (Though saving a few bytes seems like it
might be better done in the code that generates help.h rather than
directly in the source, since tabs make careful ASCII art layout hard
enough that we regularly have things misaligned.)
Remove trailing periods (most of which seem to have been added by me).
Always use the US "human readable" rather than my British
"human-readable", and be more consistent about declaring whether we're
showing multiples of 1000 or 1024.
Just say "verbose" rather than adding a useless "mode" or "output".

I realized (after being questioned about my motivation) that I hadn't
added a test for the -u behavior. Adding the missing test confirmed the
usual "if there isn't a test, the code is broken", but now I think I
actually understand how we're supposed to choose between DIR, $TMPDIR,
and /tmp. I've added more tests to back this up, and rewritten the code
one more time so that we pass all the tests.

Old versions of glibc had warn_unused_result on mktemp(3), despite it
always returning its argument. Still, we can silence the warning and
save a line, so...

Don't hard-code Linux's buffer size.
|

Even if we don't build ps, we can't have a Linux-only struct in GLOBALS.
The obvious alternative to this would be to have a fake struct sysinfo
in lib/portability.h. Since having a real macOS replacement for
sysinfo(2) seems unlikely at this point, I went this route instead.

The new tests pass on the host (coreutils 8.28) and with toybox after
this patch is applied.

bionic, glibc, macOS, and musl all have strcasestr
(see http://man7.org/linux/man-pages/man3/strstr.3.html).
macOS (via BSD) has a strnstr that does what strnstr sounds like it
should do by analogy with strnlen and strncpy.
So we at least need to rename strnstr, but it probably makes more sense
just to switch to strcasestr instead.

Used by OTA package scripts in AOSP, and quite widely inside Google.
I've also added --lines because it seems crazy to support one and not
the other, and --lines is also widly used inside Google too.

There are a bunch of if (!memcmp(s+28,...)) lines,
let's make them "else if"

default in Yocto 2.6 Thud release" and identified several error_exit() and
friends that should use the _raw versions.

At least the AOSP build doesn't try to _set_ the hostname...
|
|
I actually only need --quiet to build AOSP, but it seems weird to add
--quiet as a synonym for -s but _not_ add the more obviously related
--silent.

AOSP doesn't need -a specifically, but since it's needed for -s we may
as well accept it too.
|
|
I assume it's actually meaningful on BSD/macOS and makes them behave
like us, but I don't have access to a Mac to test that theory.
|
|
Both occur in AOSP. (Until I looked, I had no idea there were _two_
long versions of -p...)

(Alas, llvm doesn't understand -Wno-maybe-uninitialized yet.)

xparsetime() not to need floating point, adjust callers.

remove curly brackets around single line if().
|
|
`errno` isn't meaningful here.
|
|
Also improve the -l output to include sections (because you need to
know whether you're dealing with a pathconf variable to supply the
required path).
|
|
glibc doesn't have _XOPEN_UUCP (though bionic does), which meant that the
generated array of values was out of sync with the hand-written array of
names.
This patch removes that by using a unified array and the preprocessor.
A side benefit of this for me is that it makes toybox easier to integrate
in the AOSP build system (the less shell script magic, the better).
|
|
It's possible that we should just pull setprop back out of toybox to
live with getprop in system/core/, but this lets us build the same toybox
configuration for device and host in AOSP.
(Longer term we'd like to use host bionic, but if we enable this we
can start experimenting on the tobyox side before the bionic side is
finished.)
