Package: procps
Version: 2:3.3.15-2
Severity: normal
snice has no effect on process priority anymore, neither when invoked with the
process
name, nor with a user name.
With version 3.3.9 it worked fine. I did not test versions in-between.
Running a process of:
sleep 3600
And doing:
snice +20 sleep
Results in the following strace snippet for 3.3.15:
openat(AT_FDCWD, "/proc/7135/stat", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
read(4, "7135 (sleep) S 6836 7135 6836 34"..., 128) = 128
close(4)
Downgrading to 3.3.9 and repeating:
openat(AT_FDCWD, "/proc/7135/stat", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
read(4, "7135 (sleep) S 6836 7135 6836 34"..., 128) = 128
openat(AT_FDCWD, "/proc/tty/drivers", O_RDONLY) = 5
read(5, "/dev/tty /dev/tty "..., 9999) = 465
close(5) = 0
stat("/dev/pts2", 0x7fff202e0460) = -1 ENOENT (No such file or
directory)
stat("/dev/pts", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0
readlink("/proc/7135/fd/2", "/dev/pts/2", 127) = 10
stat("/dev/pts/2", {st_mode=S_IFCHR|0600, st_rdev=makedev(0x88, 0x2), ...}) = 0
setpriority(PRIO_PROCESS, 7135, 20) = 0
close(4)
