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.

(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 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).
Bug: 29092208

use generated constant for stat field parsing loop.
|
|
when trimmed for screen width), make ARGS path trimming logic work with
spaces in path.
|
|
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.
|
|
This fixes the existing test. Internal Android bug 28877702.
I've left -l as-is, even though the desktop doesn't support that.
|
|
let them overflow and try to reclaim extra space from later short fields.
|
|
calculations instead of doing strlen() on strings again to store lengths.
|
|
|
|
|

Also enable the same behavior we have with ps, where adding a thread-related
field implies that you're interested in threads.
Also clean up the help text slightly --- we're still not including the
TOP_COMMON help, but at least when we do, we'll have each option covered with
no duplicates.
|
|
The use of TT.time to determine whether to use \r or \n is a little odd,
but let's stick with that for now. Correct the spelling of millitime and
add a test.

Add ps -o BIT,TID,TCNT, and make -T display "PID,TID" for default output types
(adding TCNT to -f)
|
|
The ps.c change allows us to start. The interestingtimes.c change allows
us to clean up properly afterwards if you ^C out (which you usually do).
Tested with both ssh and "adb shell" (the latter being where I noticed
the problem).
|
|
Batch mode should never output terminal escape sequences, should ignore
the keyboard, and should include a gap between datasets.

major/minor/makedev, but glibc has vowed to break existing programs
(https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html)
and replace it with _another_ non-standard header (not in posix or lsb),
so let's just add functions to lib/ that do the transform ourselves.

down move way down past end of list.
|
|
|
|
Still need to do the cpu(s) line in top.
|
|
(Still truncates at the right edge to fit terminal width, but last commit
made -w the default when no terminal width detected.)
|
|
when we haven't got a terminal width. Replace top CMDLINE with ARGS.
More ps infrastructure genericization: parse reverse unconditionally.
Break out get_headers() with global references moved to caller.
change quick_ko() to default_ko() (dlist_terminate is now caller's job).
|
|
the start of -h HEADER (mostly parses text, but doesn't display %ESCAPES yet).
Added UP, DOWN, and R keys.
Made only iotop STAYROOT (not top), added comment explaining why.
Bumped iotop's historical -O and -K to capital letters.
Added quick_ko() to add argument list from string instead of arg_list.
|
|
Make fallback sort do string sort after numeric tie, retain absolute uptime
even though relative is needed for %CPU (hence utime2).
|
|
|
|
While I'm there, pack the ps help text, break out TOP_COMMON (todo: update
config2help to collate that properly), add -o CPU showing which processor
this pid is running on, implement -o C (it's %cpu without the fractional
part), add -o %MEM, fix header padding.
|
|
Still need to do -n and -o.
|
|
|
|
Also, I forgot to check in uuid_show() last time.
|
|
Needs testing and a few more options connected up.

Lotsa TODOs: Currently exit it with ctrl-c, not q.
Doesn't show totals, PID instead ofTID, PR instead of PRIO (type/pri),
human_readable can't display fixed point, IO isn't a percentage,
COMM instead of COMMAND (so no [kernelthread] brackets), and no
cursor left/right to change sort field...
|
|
corresponding percentile fields to ps. Move FLAG_ macro usage to ps-specific
code (top/iotop have their own flag contexts). Split init and match code
into shared and ps-specific parts. Fix bug in COMMAND for privileged processes.
|
|
(Moved header a while ago, forgot to check in function move.)
|
|
These three are currently available in Android's ps but not in toybox ps.
|
|
(leading underscore version is 1<<NAME_TAG version, with 1LL for >31 shift),
suck lots of magic constants out of ps and use tag macros instead,
redo command line display so there's now 6 variants (CMD COMM ARGS from posix,
NAME CMDLINE from android, and COMMAND for completeness). Document more
cases where posix is nuts or widely ignored.
