* Add "comm" as a format spec to psAndrea Monaco2021-12-081-0/+13
| | | | | comm was not recognized by Hurd's ps as a format spec, but is required by POSIX to display the command name (like "exe", but without the full path).
* libps: support getting RPC names for WAIT outputSamuel Thibault2020-11-231-1/+7
| | | | | | | | | | | * libps/Makefile (SRCS): Add ../utils/msgids.c. (../utils/msgids-CPPFLAGS): Add DATADIR macro. * libps/spec.c: Include "../utils/msgids.h". (get_rpc_name): Implement with msgid_info. * utils/msgids.c (parse_opt): Move end code to ... (msgids_scan_std): ... new function. * utils/msgids.h (msgids_scan_std): New prototype. * utils/ps.c (main): Call msgids_scan_std.
* Implement /proc/<pid>/exeSamuel Thibault2018-01-081-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | by adding proc_set/get_exe to the proc server, making exec call proc_set_exe, and libps call proc_get_exe. procfs can then just retrieve the information to make the "exe" symlink. * hurd/process.defs (proc_set_exe, proc_get_exe): New RPCs. * hurd/process_request.defs: Likewise. * hurd/process_reply.defs: Add skips for proc_set_exe and proc_get_exe RPCs. * proc/proc.h (struct proc): Add `exe' field. * proc/info.c (S_proc_set_exe, S_proc_get_exe): New functions. * proc/mgt.c (process_has_exited): Free p->exe. (S_proc_child): Duplicate parent `exe' into child's `exe'. * exec/exec.c (do_exec): Call proc_set_exe when a filename is available. * libps/ps.h (struct proc_stat): Add `exe_vm_alloced', `exe', and `exe_len' field.
