Read any PT_NOTE sections to look for NT_GNU_BUILD_ID or Android API
level notes. I deliberately didn't NT_GNU_ABI_TAG because it's noisy --
every Linux executable has one -- but not something most command-line
users will have any use for. (And you can ask readelf(1) anyway.)
Also read the section headers to implement "stripped"/"not stripped".
This patch removes "uses %d libs" because it was actually just counting
dynamic sections in the ELF file, and there are only 0 or 1 of those in
a valid ELF flie. (If you really want this functionality, you have to
*parse* the dynamic section looking for the DT_NEEDED entries. But that's
more of a job for readelf(1) than file(1).)

In main.c: used adjusted string with placeholers for removed options (so flag
values don't move based on config, allowing FORCE_FLAGS to work).
In scripts/mkflags.c: test was wrong, a bare longopt never matches a single
letter command, but it was treated as always matching when comparing
allyesconfig vs current config to determine which options were disabled, so
there was a corner case that got the flag values wrong.

nandread was MTD-only, and we don't support MTD any more.

top switched over a week or two back, and log switched today.

It turns out that "default" goes nowhere. Whereas "silent" actually shows
up in the log. So document "silent" (which we already supported) but
remove support for "default".
Also make the spacing between levels in the help more regular; it looks
weird being in columns when there's only one row!

It should come as no surprise to those who followed the development of
this that it's not well known which of the various names is actually the
thread name. Adding "thread" to the ps --help output seems like a good
idea.
I'm also assuming that "stat2" was meant to read "stat[2]", since that's
how it mostly appeared on the list while discussing this. Still fits in
80 columns.

continues to get worse, and now can't handle INT_MAX/2 either. So our
first workaround _also_ broke.
But posix says "A negative precision is taken as if the precision were
omitted." and that _doesn't_ trigger the glibc bug, so use that instead.

(Ubuntu's netstat is left justifying the inode field, and they're wrong.)

7ca5dc4232b9ac5ee5cd25c8b5b33a58904cd251 didn't switch all callers over
to the new functions.

Spotted while trying to diff netstat -nt against toybox netstat -nt.
|
|
(I forget who reported this bug, wasn't me.)
|

We killed toolbox ioctl and wouldn't build a toybox one anyway.
Also admit that -- although toybox has a grep -- we're not actually using
it yet (and why we're not).

constraints while still trying to get sane behavior. Discard the old CMD,
move COMM to CMD, move the old NAME to COMM, and move TNAME to NAME.
Posix assumes argv[] is the only source of process name data, but Linux has
three sources (/proc/$PID/cmdline, /proc/$PID/exe, /proc/$PID/stat field 2)
and android uses multiple sources simultaneously to identify its processes
and threads.
Toybox ps also assumes that the field names displayed in the headers
can be fed to -o to get that output, which is an assumption posix's
ps spec clearly does not have. Before we were erring on the side of posix,
now we're erring on the side of sanity.
CMD now shows stat[2], all the time. The posix -f behavior change is now
just an ARGS=CMD alias in the -f default command line, which -o overrides.
(Before -f changed the behavior of -o CMD, which is closer to what
posix says but is _insane_ and we've stopped doing it.)
COMM now shows /proc/$PID/exe minus the path. (I'm aware posix says argv[0]
here, but it says argv everywhere.)
NAME is now argv[0] of $PID.
TNAME went away.
Both $COMM and $NAME show the data for $PID, which is a thread's parent
process when $TID != $PID.

field (that's the ptb/tb switching in get_ps) so it's never blank, so
this doesn't trigger. (Conditionally initializing it would save runtime
memory, but at the expense of more complex code.)

"NAME" is no longer doing what we want; "TNAME" is what "NAME" used to be,
except that "TNAME" implies -T. This patch switches us over to "TNAME",
disables the implicit -T.

"toybuf" should be initialized before calling symlinkat() or
dangling link could occur.
|
|
(Still fixing the fallout from that "Don't truncate number fields" logic rewrite.)

argv[0]. If that's blank, show [stat2]."
That way threads show their parents, parents show themselves, and
kernel threads show the [stat2] name.

The latest tagged version is 0.7.1.

The man page says they also return 2 for syntax errors and 3 for "fatal
error: out of memory etc", but I don't know how to implement that and
don't need it (or have any reason to believe anyone needs it).

when trimmed for screen width), make ARGS path trimming logic work with
spaces in path.
|

Unstable sorting means confusing diffs if you're checking in the generated
files. (Which I shouldn't be doing, but getting this bundle of random scripts
into Android's build system isn't going to be easy...)

and the collate logic wasn't updated. (Oops.)
|
|
I don't know that anyone cares, but these failures made me think I'd
broken something while testing the -SIGNAL patch.
The -s parsing wasn't taking into account that -s 0 is a special case,
and the -o test was assuming that pkill can tell the difference between
two processes started at roughly the same time. Hopefully there's
higher-resolution data available that can avoid the need for yet another
sleep in the tests.
