This only implements the format specifiers that I've seen used in the
wild (which is actually a significant fraction of the total supported by
findutils' find). The most obvious gap is in the time support. I'm happy
to add more, but didn't want to add stuff "just because".
I'd say %A@, %C@, and -- for SELinux users -- %Z are probably the most
plausibly useful formats still missing. I don't think the human-readable
date formatting is particularly useful unless someone's seen it actually
used in the wild. The %T+ "full ISO" format being the most likely
exception to that.
Anyway, this is enough for me get started building AOSP with toybox find.

add overflow test.

Factor out the inotify code and add a kqueue equivalent.

BSDs too, given that I worked from the FreeBSD man page...

out of scope), but the AOSP build airlock doesn't provide bzcat and friends.
So tar needs to be able to use both: check for *zcat first, and fall back to
"compressor -d" if it's not there.

Found trying to build the aosp_cf_x86_phone-userdebug target. The good
news is that the targets that I knew were using tar with sparse files
all pass now.

There's no possible use for this, but debian's tar produces it, so...

And fix tar cv to produce output to stderr when archive going to stdout.

Instead have one target string and fill it out from start to finish writing
to each location once.

This is what GNU tar does, so Android's build system jail allows
bzip2, gzip, and xz, but not bzcat, zcat, and xzcat.
Why the function? Because auto-detection works by setting toyflags, so
we need to make sure we test the flags late, so it's either two copies
of this or a function.

POSIX finally gave us a way to use echo in a portable way despite
differences of opinion about whether to default interpretation of escape
sequences to on or off: -e enables and -E disables (as already
implemented by busybox and coreutils).

Commit 9448c33944651c1644ffbd0f52cf9d43cae19599 broke ELF note parsing,
because the bounds checking was off. Fix that but also generalize it so
that we won't need note-specific bounds checking in future.

There's probably more to do, but it seems usable at this point.

Gentoo removes verbosely when building packages, for example vim-core:
https://github.com/gentoo/gentoo/blob/665eaa8/app-editors/vim-core/vim-core-8.1.0648.ebuild#L120
Implement like toy cp, without prepending an escape sign to quotation
marks in filenames. Document in a test this difference from coreutils
but similarity to busybox. How do other implementations handle such
escapes? If it matters, would you approach it with a loop and multiple
prints or somehow else?
Short help description follows 141a075, consistent with other commands.

The return value of -exec was the command's exit code, which did not
account for the fact that an exit code of zero means success, while in
C, zero means failure. From POSIX:
> the primary shall evaluate as true if the utility returns a zero
> value as exit status
This commit flips the return value, and adds two tests.

Also be a bit more consistent about `COMMAND [ARG...]` in usage text.

Also add a test, and add a test for timeout now it's been fixed.

Sunday's transition in the US broke a bunch of the tests. Worse, it
broke some of the QA folks' scripts. Finally, the boil that is date's
handling of time zones and daylight time has come to a head...
This patch fixes the newly-failing tests *and* the other tests that were
checked in failing to serve as TODOs.
I've resolved the test TODOs about whether implied year/century in POSIX
format should mean the current year or 1900 in favor of the current
year. Both busybox and coreutils agree, and Rob fixed the code recently
so toybox agrees too, but without fixing the tests.
I've switched tests from Europe/London to Europe/Berlin to avoid
disagreements between C libraries about whether to say "GMT" or "UTC"
when daylight savings is not in force.
The majority of this patch implements what I'd been unsuccessfully
trying to explain on the list: that to correctly implement the distinct
input and output time zones (as demonstrated in the three failing tests
we've been carrying around for a while), we should switch to working
with time_t internally rather than struct tm. I've also added the code
to temporarily switch to the input time zone (and back again).
All the tests now pass.

--signal is simply a synonym for the exiting -s.
--foreground disables functionality we didn't yet have: putting the
child into a new process group. I've added the functionality and the
flag to disable it.
--preserve-status also makes it clear that our exit statuses didn't match
the coreutils version. In addition to callers that use --preserve-status
to get away from this madness, I also have callers that check for
specific exit values. This patch implements --preserve-status but also
fixes all the other exit statuses.
(The "125" exit value is broken for toybox in the same way that
`toybox grep --whoops ; echo $?` is. To fix this, we'd need some way to
signal that command-line parsing failures should exit with a different
value than the usual 1 --- 2 for grep, 125 for timeout. I've done as much
as grep manages, and left a TODO.)
Also add timeout tests. I couldn't think of an easy test for
--foreground, so I tested that manually with strace.
Also add some newlines to the `toybox --help` output to make it easier
to find the different sections, and expand the section on durations to
call out that fractions are supported as a matter of policy.
As long as timeout and sleep have text describing the duration syntax,
make them the same. (Personally I'd remove both in favor of the `toybox
--help` output, but as long as they're duplicated, keep them consistent.)
Also remove the SLEEP_FLOAT variant --- xparsetime means that sleep no
longer requires floating point to support sub-second resolution.

Tested manually on an Android device with:
adb shell find /system -context u:object_r:wait_for_keymaster_exec:s0
adb shell find /system/bin -context '"*key*"'
adb shell find /system/bin -context '"*tool*"'

It's in the Linux 5 kernel headers. If, like me, you'd never heard of
