wiz 8c6310c4a3 Remove duplicate `if'. Noted by Geoff C. Wing in bin/13551. 2001-07-30 16:22:49 +00:00
matt c6458f33d8 Add a small optimizetion in savevars(). break out of the loop once needcomm
is set since setting it multiple times only wastes cpu time.

cyber 428f40d685 If there were no processes to list, it meant that our criteria failed
and didnt match anything.  Dont make our caller think we succeeded.

simonb 643cb3c341 Don't check namelist when choosing to use the sysctl interface. 2000-06-16 03:51:00 +00:00
simonb d530ee00d1 Fix handling of "ps U<user>" where <user> ended it 't' - now if the
first argument doesn't start with a '-' and ends in 't', the 't' only
gets converted to a 'T' (for listing processes on the current tty)
if it doesn't contain any other command line option characters that
take an argument.  Problem noticed by ITOH Yasufumi on tech-userlevel.

If the 'start' format was the last column, the width wouldn't be set
and started() output a zero length string instead of a string the right
length - fix header width calculations so the the last column is handled
the same all others.  This only showed up for 'start' because started()
knew that the column header is the same width and the field itself...

Update copyrights.

simonb a98dd470c6 Calculate field widths on the fly so that all columns line up nicely
and make more effective use of screen real estate when some columns
(eg USER and VSZ) didn't need the full default width.

simonb fd521aefe9 Use new sysctl/kvm interfaces. This will stop the "proc size mismatch"
errors when internal kernel structures change size.  Also remove
the sgid bit - all live kernel data is accessed through the sysctl
interface.

abs 22cfbf2cbb If ps cannot get the terminal size from STDOUT, it tried STDERR and STDIN.
What this does to the POLS when a script that is parsing ps output just happens
to run in a narrow terminal cannot be described in polite company.
If STDOUT is not a tty, leave width at 80.

simonb 8384a1bbb8 Use tty "?" to select processes with no controlling tty and tty "-" to
select processes with a revoked controlling tty.

Idea from SunOS/Solaris, suggested by Alexis Rosen.

jdolecek a5ae7c6ca4 command(): don't start using procfs_getargv() instead of kvm_getargv()
just because the latter returned a NULL - that may normally happen,
when the process is, for example, a kernel thread

procfs_getargv(): if the name is brackened in '(' and ')', just
	return NULL immediately - the code in command() will DTRT
	and the output will be same for procfs- and kvm- based lookup
	in all cases

jdolecek e52880e76a getkinfo_kvm(): fix bug in previous - handled size_t i as if it would be signed

jdolecek f848d2ec0c When using the procfs for extracting process information, extract
also process start time, process arguments and session leadership status.

The procfs fallback is also used when kvm_openfiles() completely fails
(e.g. when /dev/mem is not readable).

Solves PR 7772, though the final implementation is different.

bgrayson 05e0706ac9 Minor fixes:
1.  Use statfs() to verify that /proc is a procfs.
2.  Add -K option to disable /proc-based method.
3.  Make warnings less verbose, but still accurate.
1999-03-27 21:38:08 +00:00
bgrayson be8534f744 Added experimental fallback /proc-based lookup. Warnings are printed when the
fallback method is used, as the results could be untrustworthy if an
intruder is present.  It is highly likely that NetBSD-1.5 will have
an improved kvm interface for reading process information, at which
point this code can be garbage-collected.  Also added a word to the
man page -x option description while I was here.

kim 26cc4401e8 Fixed segfaulting for "ps -T". There is no optarg with -T, so instructions
under label "tty:" need to use ttname instead.

mrg 80efe80bc9 - change setgid kmem programs (that lend themselves to this) so setegid(getgid())
and the top, and then set the effective gid back to kmem around the call to
  kvm_openfiles().  this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
  kvm_openfiles() to fully revoke priviledges.
- some KNF
- use err(3) over fprintf(3) in some places
