* misc: consolidate macro style USAGE_HELP_OPTIONSRuediger Meier2017-06-291-2/+2
| | | | | | | | | changed in include/c.h and applied via sed: sed -i 's/fprintf.*\(USAGE_MAN_TAIL.*\)/printf(\1/' $(git ls-files -- "*.c") sed -i 's/print_usage_help_options\(.*\);/printf(USAGE_HELP_OPTIONS\1);/' $(git ls-files -- "*.c") Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: introduce print_usage_help_options()Ruediger Meier2017-06-271-2/+1Star
| | | | | | | | | | | | Consolidate --help and --version descriptions. We are now able to align them to the other options. We changed include/c.h. The rest of this patch was generated by sed, plus manually setting the right alignment numbers. We do not change anything but white spaces in the --help output.

* misc: never use usage(ERROR)Ruediger Meier2017-06-261-6/+8
| | | | | | | | | | We are using better/shorter error messages and somtimes also errtryhelp(). Here we fix all cases where the usage function took an int argument for exit_code. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* Use --help suggestion on invalid optionKarel Zak2016-12-191-5/+2Star
| | | | | | | | The current default is to print all usage() output. This is overkill in many case. Addresses: https://github.com/karelzak/util-linux/issues/338 Signed-off-by: Karel Zak <kzak@redhat.com>
* chrt: default to SCHED_RR policyAndreas Henriksson2016-12-051-1/+1
| | | | | | | | | | | | | | | | | This fixes a regression introduced in: commit 7a4ea5664edba98bff28adec3a9c3cfb5763a495 "chrt: add control struct" Previously (and as documented in the manpage) the default policy was SCHED_RR. Now it's implicitly SCHED_OTHER (0) as the value is not initialized explicitly anymore. Test-command: chrt 90 echo hello Reported-by: Patrick Pelissier <patrick.pelissier@gmail.com> Addresses: http://bugs.debian.org/846572 Signed-off-by: Andreas Henriksson <andreas@fatal.se>
* chrt: fix HAVE_SCHED_SETATTR fallback caseRuediger Meier2016-10-271-2/+3
| | | | | | | | | | | Broken since 6f27e449. We could not enter the fallback if HAVE_SCHED_SETATTR is not defined. Two gcc warnings made this issue visible: schedutils/chrt.c:247:1: warning: label 'fallback' defined but not used [-Wunused-label] schedutils/chrt.c:266:9: warning: 'policy' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* chrt: follow nice setting, prefer sched_setscheduler()Karel Zak2016-10-031-16/+18
| | | | | | | | | | | | | | | | * do not reset 'nice' setting by sched_setattr(), if 'nice' setting is not zero then chrt ends with EPERM for non-root users: $ renice -n 5 -p $$; chrt -v -b 0 date 12475 (process ID) old priority 0, new priority 5 chrt: failed to set pid 0's policy: Operation not permitted * it seems more elegant to always use old sched_setscheduler() API for non-deadline policies; in this case we do not need getpriority() to keep 'nice' unchanged. Addresses: https://github.com/karelzak/util-linux/issues/359 Signed-off-by: Karel Zak <kzak@redhat.com>
* chrt: add fallback to be usable on kernels without sched_{get,set}attrKarel Zak2016-07-111-8/+43
| | | | | | | | | | We have fallback for compilation with/without proper glibc and kernel headers, but it's not enough, because people can switch between kernels with and without the syscalls. (For example RT kernels for RHEL/CentOS). Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1353340 Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | Earlier message: $ chrt -i 1 ls chrt: failed to set pid 0's policy: Invalid argument basically told 'something failed', while the new one tries to be more helpful. $ chrt -i 1 ls chrt: unsupported priority value for the policy: 1: see --max for valid range Addresses: https://bugs.debian.org/791707 Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* chrt: make --sched-* short options to require an argumentSami Kerola2016-04-041-1/+1

| | | | | | | | | | | | | | This patch introduces -d, --deadline -T, --sched-runtime -D, --sched-deadline -P, --sched-period command line options. The functionality is available only for Linux with sched_setattr() [kernel >=3.14] Signed-off-by: Karel Zak <kzak@redhat.com>

* build-sys: provide alternatives for err, errx, warn and warnxFabian Groffen2011-02-141-1/+0Star
| | | | | | | | Solaris lacks err, errx, warn and warnx. This also means the err.h header doesn't exist. Removed err.h include from all files, and included err.h from c.h instead if it exists, otherwise alternatives are provided. Signed-off-by: Fabian Groffen <grobian@gentoo.org>
* lib: [strutils] general purpose string handling functionsDavidlohr Bueso2010-11-231-3/+3
