-------------------------- general ------------------------
|
|
|
|
Implement /usr/proc/bin tools like Solaris has.
|
|
The prstat command is interesting, like top in batch mode.
|
|
|
|
Don't these really belong in the procps package?
|
|
killall pstree fuser lsof who
|
|
(they are maintained elsewhere, which causes version problems)
|
|
|
|
Cache results of dev_to_tty.
|
|
|
|
---------------------- kernel -------------------------
|
|
|
|
Add an "adopted child" flag to mark processes that are not
|
|
natural children of init. This can make --forest work better.
|
|
|
|
Add a thread group ID, to be shared by all tasks that are related by
|
|
the clone() system call. This ID might be made unique from boot to
|
|
shutdown, perhaps being a 16-bit CPU number and 48-bit per-CPU
|
|
serial number.
|
|
|
|
Make the kernel group /proc listing output by thread group.
|
|
Without this, a thread-aware ps must always sort processes.
|
|
|
|
Supply the task ID (the "PID"/"TID") of the thread group leader.
|
|
I define "leader" as the first process of a thread group.
|
|
|
|
Don't reuse the task ID of a thread group leader until all threads
|
|
are dead. Better yet, don't let the leader exit.
|
|
|
|
Supply better data for top's CPU state display. Currently top has
|
|
to subtract old numbers from new numbers and divide that result by
|
|
the number of processors. The kernel won't even supply the number
|
|
of processors in a portable way.
|
|
|
|
Mark threads, and supply a list of other threads.
|
|
|
|
Supply data for the ADDR and JOBC fields.
|
|
|
|
Support & supply data for SL and RE.
|
|
|
|
Add a /proc/*/tty symlink to eliminate guessing when /proc/*/fd is
|
|
not accessable.
|
|
|
|
Put unique ID at the top of System.map and in /proc, to make sure
|
|
there is never a mismatch.
|
|
|
|
Add /proc/*/.bindata files to avoid string parsing. It should be an array
|
|
of 64-bit values on all machines. New entries go on the end and obsolete
|
|
ones get filled in with something logical -- entries must never be deleted!
|
|
|
|
Add all the stuff Solaris has. This would also replace ptrace.
|
|
|
|
---------------------- w --------------------------
|
|
|
|
The LOGIN@ column sometimes has a space in it. This makes correct
|
|
scripting difficult.
|
|
|
|
Verify that DNS control does not give a user the power to specify
|
|
arbitrary data for the FROM column. (could set root's VGA color map!)
|
|
|
|
---------------------- vmstat --------------------------
|
|
|
|
Extract /proc/stat parsing from vmstat into libproc somewhere.
|
|
|
|
Let the user choose: 1000, 1024, PAGE_SIZE, 1000000, 0x100000
|
|
|
|
--------------------- libproc ----------------------
|
|
|
|
Stop storing fields with duplicate info (often different
|
|
units: kB and pages, seconds and jiffies) in the proc_t struct.
|
|
|
|
---------------------- top -------------------------
|
|
|
|
Share more stuff with ps.
|
|
|
|
---------------- ps for now, maybe move to libproc ------------------
|
|
|
|
With forest output and a tty named /dev/this_is_my_tty, the position
|
|
of the command name gets messed up. (we print too many spaces) (fixed?)
|
|
|
|
Fix missing stuff for these formats: FB_j FB_l FB_v HP_f HP_l HP_fl JFMT OL_m
|
|
(jobc,cpu,sl,re,cpu,prmgrp,m_swap,m_share,vm_lib,m_dt)
|
|
Note that "cpu" has two meanings.
|
|
|
|
Add Beowulf support. This is ugly, since the current patches use a
|
|
daemon to collect info and add a HOST field after the PID field.
|
|
|
|
Query optimizer, put cheap/required process selection first.
|
|
|
|
Avoid reading both /proc/*/status and /proc/*/stat.
|
|
|
|
Maybe ps should put a 'C' in front of fields when they are affected
|
|
by cumulative mode. Debian ps did that. (move flag to common.h...)
|
|
|
|
Support printing the client hostname (the FROM that w(1) uses) in place
|
|
of a pty. Maybe do this when PS_PERSONALITY=linux.
|
|
|
|
Disambiguate narrow tty info. (/dev/tty7 == /dev/pts/7 now)
|
|
1------8 1--4
|
|
ttyS2 S2
|
|
ttyI31 I31
|
|
pts/7 7 Short form could be /999.
|
|
pts/9999 9999 Short form could just be trunctuated to /999.
|
|
tty7 7 Short form could be vc-7.
|
|
tty63 63 Short form could be vc63.
|
|
|
|
Internationalization, as specified by XPG3, Volume 1, Commands and Utilities.
|
|
(and suggested by Unix98) LC_TIME affects date format.
|
|
|
|
----------------------- ps -----------------------
|
|
|
|
Add an option to select all processes that a user can kill.
|
|
(related to RUID, EUID, tty, etc. -- but maybe ignore root power)
|
|
|
|
Add a nice display option for killing things.
|
|
ruser,euser,ppid,pid,pmem,stime,args isn't too bad
|
|
|
|
Make the column alignment algorithm support this:
|
|
FOO BAR
|
|
8 44444
|
|
453 45
|
|
45 2989
|
|
63666 0
|
|
34 333
|
|
(useful for the UNIX tty and time values, since the time might look
|
|
like 100-10:40:32 for old processes and the tty might have extra room)
|
|
|
|
Improve long sort/format specifiers documentation and fill in the missing
|
|
code as much as the kernel can support. Make sure that memory amounts are in
|
|
pages when they should be and in kB when they should be, not backwards.
|
|
|
|
output encoding: UTF8 --nul --null
|
|
|
|
Make BSD formats use non-standard BSD time format, at least when it
|
|
doesn't violate the "no whitespace" rule.
|
|
|
|
Try to make -jl fit in 80 columns. Do we need more than 1000 pty devices,
|
|
9 flag bits, etc.? (hmmm, Linux supports 2048 pty devices now, and we
|
|
might also want to steal whitespace there when the time column overflows)
|
|
|
|
When not in strict Unix98 mode, let foo=8 specify that foo is 8
|
|
characters wide. Debian did that. Then foo=8=bar and foo=bar=8
|
|
could change both header and width.
|
|
|
|
Better unmangling of '?' as a tty. The shell destroys '?' when there
|
|
is a filename that matches. If the argument seems like garbage,
|
|
check for a file that might have screwed up the '?'.
|
|
|
|
If the 'O' option is given something already implied by 'O',
|
|
assume the user wanted a sorting option.
|
|
|
|
Conflict:
|
|
Digital THREAD is user,pcpu,pri,scnt,wchan,usertime,systime
|
|
AIX THREAD is uname,pid,ppid,tid,S,C,PRI,scount,WCHAN,F,tty,bnd,comm
|
|
AIX looks like this:
|
|
USER PID PPID TID S C PRI SC WCHAN FLAG TTY BND CMD
