Annoyingly, this means writing a new dmesg implementation that uses /dev/kmsg
rather than the klogctl system call. Worse, pre-3.5 kernels don't support
that, so we need to keep the old implementation around as long as we still
care about those kernels.
Since I'm here, add the fancy colors from modern dmesg and the -C flag.
Tested on Nexus 9's 3.10 kernel, an Ubuntu 3.13 kernel, and the
Nexus One's 2.6.35 kernel.

reliably be distinguished by checking length, because %H amd %m and such
can match different numbers of digits.)
|
|
T to be a space instead (because the posix says so, no idea why), initialize
default values reliably including zeroing daylight savings time field (which is
handled inconsistently by libc and just screws stuff up).
|
|
It's causing confusion, and it's not obvious that anyone's relying on
it (and even if they are, let's try to find and fix them first).

(no /proc/$PID/cmdline so setting was skipped and previous value retained),
which led to memcpy() with an overlapping source/dest range (annoying asan).
Fix: move temp variable and assignment outside the if() statement so we assign
zero if we can''t read the file.

Say "toybox" before version string. Tweak sed to preserve lie-to-autoconf.

POSIX says nothing, but traditional ps lets you say "ps 123" in addition
to "ps -p 123". (You can mix and match too: "ps -p 123,124 666 667" works
fine.)

Android uses NAME rather than CMD by default, but that's not what we
want with -T. Noticed because it broke systrace's reporting of thread
names (see https://developer.android.com/studio/profile/systrace.html).

The recent refactoring broke ls -lh by multiplying all sizes by 0
rather than 1.

On a toybox system, most of your bin directory is symbolic links.

then reading from stdin if it detected a file). Fixed it so "-" always
means stdin and you have to say ./- to look at a local "-".
Did some whitespace tweaks while I was there...

Or more accurately, s@[[:space:]@]@replace@ which can't treat the @ in
[] as a delimiter but has to know about nested [[]] to make that decision.

(Two spaces padding between columns, and -k is hardwired on.)
|
|
(We should use xprintf and similar to flush and check if stdout went away
once per line. No point flushing partway through a line, so in ls only use it
on things outputting a newline char.)
|
|
-h should apply to -s too. (Previously it only applied to the "total"
line in -s output.)

instead of a struct. This means it can return "12345" even if that user/group
doesn't exist in /etc/passwd and similar.
All the users were immediately dereferencing it to get pw_uid or gr_gid
anyway, so just return it directly and adjust the users. This fixes
things like "chown 12345:23456 filename".

not segfault on a lookup failure (they print the number instead of UNKNOWN).
The whitespace in the default output may need some adjusting.

of number, but never NULL. Both returned in static buffer good through
next call.)

(man 2 stat says so) and %B is the units on %b (I.E. always 512), so change
output and help text. This matches what other implementations produce.

seek so seek time is included in total.

add xopenro() that takes one argument and understands "-" means stdin,
and switch over lots of users.
|
|
The IANA tzcode implementation of mktime (used on Android and BSDs) sets
errno in some cases where it doesn't return -1 to indicate failure, so the
existing test always failed on those systems.
I don't think glibc ever sets errno (which is fine by ISO C, but not POSIX).
Other uses of mktime in toybox are already fine. This one would have been
caught by the existing tests if I was running them on the device :-(
