* ps(1): Fix formatting of the "command" field for kernel threads.Mark Johnston2020-07-281-4/+7
| | | | | | | | | | | | | | | | | | When -H is specified, for kernel threads the command is formatted as "<proc name>/<td name>" and truncated to MAXCOMLEN. But each of the proc name and td name may be up to MAXCOMLEN bytes in length. Also handle the ki_moretdname field to ensure that the full thread name gets printed. This is already handled correctly when formatting for "-o tdname".

* ps(1): reuse keyword "cpu" to show CPU numberPiotr Pawel Stefaniak2020-06-275-5/+37
| | | | | | | | | | | | | | | | | | | | | | | This flag will now show the processor number on which a process is running. This change was inspired by PR129965. Initially I didn't think that the patch attached to it was correct -- it sacrificed ki_estcpu use in "cpu" for ki_lastcpu and I thought that the old functionality should be kept and the new (cpu#) one added to it. But I've since discovered that ki_estcpu is sched_4bsd-specific. What's worse, it represents the same thing as ki_pctcpu, except ki_pctcpu is universal -- so "%cpu" has been using it successfully. Therefore, I've decided to replace information based on ki_estcpu with information based on ki_oncpu/ki_lastcpu. Key parts of the code and manual changes were borrowed from top(1).

* bin/ps: Make the rtprio option actually show realtime prioritiesLorenzo Salvadore2020-06-192-10/+11
| | | | | | | | | | | | | | | | | | | | | Fix the rtprio option that for some reason was progessively becoming an option showing the priority class of threads. In particular: - use the constants defined in sys/sys/rtprio.h instead of those defined in sys/sys/priority.h: this helps making clearer that the code actually is about realtime priorities and not standard scheduler priorities; - remove the PRI_ITHD case that has nothing to do with realtime priorities; - convert the priority levels to realtime priority levels using the same formulas used for pri_to_rtp function in sys/kern/kern_resource.c. - remove outdated note "101 = not a realtime process" in the man page and replace it with a more useful reference to man 1 rtprio.

* ps: extend the non-standard option -d (tree view) to work with -pPiotr Pawel Stefaniak2020-05-071-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initially it seemed that there were multiple possible ways to do it. Processing option -p could conditionally add selected processes and their descendants to the list for further work, but it is not guaranteed to know whether the -d option has been used or not, and it also doesn't have access to the process list just yet. There is also descendant_sort() which has access to all possibly needed information, but serves the purely post-processing purpose of sorting output. Then there is the loop that uses invocation information and full process list to create a list of processes for final display. It seems the most natural place to implement this, but indeterminate state of the process list and volatility of the final list that is being created obstruct adding an elegant search for all elements of process descendancy trees. So I opted for adding another loop, just before the one I mentioned above. For all selected processes it conditionally adds direct descendants to the end of this list of selected processes.

* ps(1): Fix -w + UNLIMITED handlingConrad Meyer2017-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | A follow-up fix for r314685. Because the -w flag is parsed after ps(1) infers termwidth from COLUMNS and stdout, and UNLIMITED happens to be the zero value, the single -w flag in combination with a non-terminal stdout or COLUMNS=0 could result in output truncated at 131 characters. (Despite the output being unlimited without -w.) Obviously, adding more -w shouldn't truncate output lines. The committed patch is from bdrewery@, and I've reviewed and tested it.

* ps(1): Only detect terminal width if stdout is a ttyConrad Meyer2017-03-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If stdout isn't a tty, use unlimited width output rather than truncating to 79 characters. This is helpful for shell scripts or e.g., 'ps | grep foo'. This hardcoded width has some history: In The Beginning of History[0], the width of ps was hardcoded as 80 bytes. In 1985, Bloom@ added detection using TIOCGWINSZ on stdin.[1] In 1986, Kirk merged a change to check stdout's window size instead. In 1990, the fallback checks to stderr and stdin's TIOCGWINSZ were added by Marc@, with the commit message "new version."[2] OS X Darwin has a very similar modification to ps(1), which simply sets UNLIMITED for all non-tty outputs.[3] I've chosen to respect COLUMNS instead of behaving identically to Darwin here, but I don't feel strongly about that. We could match OS X for parity if that is desired.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
