forks/toybox - Toybox with POSIX patches from E5ten

Age	Commit message (Collapse)	Author
2016-01-01	First pass at iotop.	Rob Landley
	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...
2015-12-30	First half of iotop. Add READ, WRITE, IO, DREAD, DWRITE, SWAP, DIO, and	Rob Landley
	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.
2015-12-29	Move comma_args() from ps.c to lib.	Rob Landley
	(Moved header a while ago, forgot to check in function move.)
2015-12-21	Add ps -o psr,rtprio,sched.	Elliott Hughes
	These three are currently available in Android's ps but not in toybox ps.
2015-12-18	Next giant chunk of ps work: add _NAME_TAG bitmask values to tags.h	Rob Landley
	(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.
2015-12-12	Make "ps -o TIME+ -k TIME+" work. Factor out -o field names, field lengths,	Rob Landley
	and slot numers into a structure. (Keeping multiple arrays in sync may have been efficient but it was ugly.) Fix duplicate command name copying that corrupted the name of kernel threads. Tighten up slot[] docs.
2015-12-05	Add start of top infrastructure to ps, null terminate some stridx() searches,	Rob Landley
	move slot[] documentation into C code, add PR %VSZ VIRT RES SHR
2015-11-29	Implement ps --sort.	Rob Landley

2015-11-29	Add basic sort logic.	Rob Landley

2015-11-28	Split out string_field() from show_ps().	Rob Landley

2015-11-28	Save string offsets rather than recalculating them each time, and use struct	Rob Landley
	instead of carving up toybuf by hand. This makes breaking out the field conversion logic into its own function less expensive.
2015-11-26	Split do_ps() into get_ps() and show_ps() as a start on implementing --sort.	Rob Landley
	Change readfileat() to pass back length of read.
2015-11-09	Cleanup pass: inline find_tty_name(), bounds check fscanf(), use libc	Rob Landley
	functions to read major()/minor(), fix printf format warnings in error msg.
2015-11-09	Make ps try harder to find a name for a tty.	Elliott Hughes

2015-11-09	On Android, ps' default output should match toolbox.	Elliott Hughes

2015-11-09	Add ps -n.	Elliott Hughes
	Both Android and GNU interpret -n to mean "show numeric users and groups", despite what POSIX says.
2015-11-09	Add ps -o CMDLINE.	Elliott Hughes
	This is equivalent to Android's historical "NAME" column, showing the first element of /proc/pid/cmdline.
2015-11-02	Add -P as short option for --ppid.	Rob Landley
	(The help infrastructure can collate and alphebetize short options, long options haven't got a standardized help text format. Not a hard requirement to have a short opt, but it's nice.)
2015-11-02	Fix the ps -o CMD vs COMM distinction.	Elliott Hughes
	"comm" is the command name without arguments, and "cmd" the command line including arguments. Confusingly, "command" is a synonym for the latter, not the former. This implementation of "comm" matches the GNU ps behavior where the names are truncated, but Android historically used the full name from /proc/pid/cmdline instead, so this patch isn't sufficient to let us match the Android behavior.
2015-11-02	Make ps -o error reporting intelligible.	Elliott Hughes
	I actually thought ps was segfaulting, and it wasn't until I was in gdb that I even noticed there was an error message at all, and even then I had to read the source to work out what it was trying to tell me. Before: $ ps -o user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd ps: -o 'user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd'@41 USER PID PPID VSZ RSS NI WCHAN ADDR$ After: $ ps -o user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd ps: bad -o field 'user,pid,ppid,vsize,rss,nice,wchan,addr,unknown,stat,cmd' ^
2015-11-02	Add ps -Z.	Elliott Hughes
	As with ls, it doesn't seem like -Z should be guarded behind LSM availability. On a non-SELinux system, the label is always "unconfined".
2015-11-02	Add ps --ppid.	Elliott Hughes
	Used by Android.
2015-10-28	Promote ps to posix.	Rob Landley
