all of your

1994-05-26 06:18:55 +00:00

|

processes that have controlling terminals.

If the

Support more POSIX/SUSv3 options:
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
- various minor improvements in parsing and error handling.
This does not get us to match POSIX/SUSv3, but it gets us closer. The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.

For the processes which have been selected for display,

will usually display one line per process.

The

|
|
|
|
some processes.
|
|
|
|
By default all of these output lines are sorted first by controlling
|
2004-05-16 21:35:05 +00:00

terminal, then by process ID.

Support more POSIX/SUSv3 options:
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
- various minor improvements in parsing and error handling.
This does not get us to match POSIX/SUSv3, but it gets us closer. The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.

When a debugger attaches to the process, SIGSTOP is sent to the
target. Due to a way issignal() selects the next signal to deliver
and report, if the simultaneous or already pending another signal
exists, that signal might be reported by the next waitpid(2) call.
This causes minor annoyance for debuggers, which must be prepared to
take any signal as the first event, then filter SIGSTOP later.
More importantly, for tools like gcore(1), which attach and then
detach without processing events, SIGSTOP might leak to be delivered
after PT_DETACH. This results in the process being unintentionally
stopped after detach, which is fatal for automatic tools.
The solution is to force SIGSTOP to be the first signal reported after
the attach. Attach code is modified to set P2_PTRACE_FSTP to indicate
that the attaching ritual was not yet finished, and issignal() prefers
SIGSTOP in that condition. Also, the thread which handles
P2_PTRACE_FSTP is made to guarantee to own p_xthread during the first
waitpid(2). All that ensures that SIGSTOP is consumed first.
Additionally, if P2_PTRACE_FSTP is still set on detach, which means
that waitpid(2) was not called at all, SIGSTOP is removed from the
queue, ensuring that the process is resumed on detach.
In issignal(), when acting on STOPing signals, remove the signal from
queue before suspending. Otherwise parallel attach could result in
ptracestop() acting on that STOP as if it was the STOP signal from the
attach. Then SIGSTOP from attach leaks again.
As a minor refactoring, some bits of the common attach code is moved
to new helper proc_set_traced().

|
.Pa /dev/tty ,

or, for pseudo-terminals, the corresponding entry in

|
|

controlling terminal (i.e., it has been revoked).

A
|
|

without a preceding two letter abbreviation or pseudo-terminal device number
|
|

indicates a process which never had a controlling terminal.
|
2011-10-01 23:47:37 +00:00
|
|
|
The full pathname of the controlling terminal is available via the

|

keyword.

.It Cm wchan
|
1994-05-26 06:18:55 +00:00
|
|
|
The event (an address in the system) on which a process waits.
|
|
|
|
When printed numerically, the initial part of the address is
|
|
|
|
trimmed off and the result is printed in hex, for example, 0x80324000 prints
|
|
|
|
as 324000.
|
|
|
|
.El
|
|
|
|
.Pp
|
|
|
|
When printing using the command keyword, a process that has exited and
|
|
|
|
has a parent that has not yet waited for the process (in other words, a zombie)
|
2004-05-16 21:35:05 +00:00
|
|
|
is listed as
|
|
|
|
.Dq Li <defunct> ,
|
|
|
|
and a process which is blocked while trying
|
|
|
|
to exit is listed as
|
|
|
|
.Dq Li <exiting> .
|
2005-02-14 16:56:15 +00:00
|
|
|
If the arguments cannot be located (usually because it has not been set, as is
|
|
|
|
the case of system processes and/or kernel threads) the command name is printed
|
|
|
|
within square brackets.
|
2002-04-16 20:08:06 +00:00
|
|
|
The
|
|
|
|
.Nm
|
2005-02-14 16:56:15 +00:00
|
|
|
utility first tries to obtain the arguments cached by the kernel (if they were
|
|
|
|
shorter than the value of the
|
|
|
|
.Va kern.ps_arg_cache_limit
|
|
|
|
sysctl).
|
|
|
|
The process can change the arguments shown with
|
|
|
|
.Xr setproctitle 3 .
|
|
|
|
Otherwise,
|
|
|
|
.Nm
|
1994-05-26 06:18:55 +00:00
|
|
|
makes an educated guess as to the file name and arguments given when the
|
|
|
|
process was created by examining memory or the swap area.
|
|
|
|
The method is inherently somewhat unreliable and in any event a process
|
2005-02-14 16:56:15 +00:00
|
|
|
is entitled to destroy this information.
|
1994-05-26 06:18:55 +00:00
|
|
|
The ucomm (accounting) keyword can, however, be depended on.
|
2005-02-14 16:56:15 +00:00
|
|
|
If the arguments are unavailable or do not agree with the ucomm keyword,
|
|
|
|
the value for the ucomm keyword is appended to the arguments in parentheses.

Support more POSIX/SUSv3 options:
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
- various minor improvements in parsing and error handling.
This does not get us to match POSIX/SUSv3, but it gets us closer. The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.
