Even after a reboot we get this: $ sv start ./service/unicorn/ timeout: down: ./service/unicorn/: 1s, normally up, want up This has just started without (as far as we can tell) there being any change to the server. I've even nuked the ./service/* directory so that it will get rebuilt when the application is deployed (via capistrano - this is a Rails app) but that does not seem to help. The other 23 servers which are set up in the same way have no problem so I am at a loss as to where to start looking. Any idea of where I should look for clues? </pre> Peter Hickman 2013-05-22T09:30:54 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2200 <pre>I'd like to allow any user to access supervise/ok, in order to run `sv stat`, but not to access supervise/control. My understanding is that this is safe, as supervise/ok is a read-only interface. Is this accurate, and is this a reasonable idea? Anything I should be warned about? Am I overlooking anything important? chmod 755 supervise chmod 666 supervise/ok </pre> eam< at >frap.net 2013-05-20T23:52:58 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2198 <pre>Hi This seems to be corner case as I have never before set the flag-usert, flag-usemon, flag-noipv6, flag-forcedevr flags for skalibs. exec ./compile s6-ln.c exec ./load s6-ln -lrandom -lstdcrypto -lstddjb `cat socket.lib` /package/prog/skalibs/library/libstddjb.a(taia_clockmon.o): In function `taia_clockmon': taia_clockmon.c:(.text+0x22): undefined reference to `clock_gettime' /package/prog/skalibs/library/libstddjb.a(taia_clockmon.o): In function `taia_clockmon_init': taia_clockmon.c:(.text+0xce): undefined reference to `clock_gettime' /package/prog/skalibs/library/libstddjb.a(sysclock_get.o): In function `sysclock_get': sysclock_get.c:(.text+0x21): undefined reference to `clock_gettime' collect2: ld returned 1 exit status make[2]: *** [s6-ln] Error 1 make[2]: Leaving directory `/package/admin/s6-portable-utils-1.0.0/compile/skaembutils' make[1]: *** [.done] Error 2 make[1]: Leaving directory `/package/admin/s6-portable-utils-1.0.0/compile/skaembutils' make: *** [.done] Error 2 </pre> Vallo Kallaste 2013-05-14T20:17:43 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2189 <pre>I've installed runit on a Centos 5.8 box thus wget http://smarden.org/runit/runit-2.1.1.tar.gz tar zxf runit-2.1.1.tar.gz (cd admin/runit-2.1.1; ./package/install; ./package/install-man) No problem with that (so far) but when I compare it to my Ubuntu 10.04 installation I seem to be missing things like 1) /etc/sv and /etc/service 2) When is ps ax it does not appear to be running anywhere... 3) The sv command only seems to be available to root, unlike on Ubunto where other accounts can access it Have I missed a step in the installation somewhere.

Or does the log/run supersede the myservice/run script? * The directory specified in the log run script to svlogd (eg ./main)--does this live in the log directory? * Do I need to create the log directory or does the svlogd directory do that for me * Where does the log go? I've looked in this main directory, and it is still empty.

This release fixes a very rare bug in s6-log. It also includes the ucspilogd program (previously shipped as a standalone package). Most importantly, it adds support for non-slashpackage installations, which means that distributors may now install the binaries wherever they want. http://skarnet.org/software/s6/ Enjoy, Bug-reports welcome. </pre> Laurent Bercot 2013-02-12T10:38:01 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2181 <pre>Announcing the latest release of perp, a persistent process supervisor and service management framework for un!x: http://b0llix.net/perp/distfiles/perp-2.07.tar.gz What's New: * not much! * PERP_SVPID and PERP_SVSECS defined for reset runscripts! * slightly bigger release number! * not much else!

Some data: * I don't have strace output at hand, but from memory it was infinite stream of identical poll() related lines. * s6-log runs as: s6-log -b s16777215 n25 S0 !xz -0q /var/service/nslcd/log * Happens only for service loggers missing the log/state file. Most service loggers do not have the log/state file, this is probably my mistake in some deployment script. * There are following lines in s6-svscan log: s6-log (processor child): fatal: unable to open_readb /var/service/nslcd/log/state: No such file or directory s6-log: warning: processor failed in /var/service/nslcd/log It seems that this is caused by my mistake but perhaps it could be handled better?

A diff against "vendor" branch shows all changes. Features: - '-N' reopens '-012' to /dev/null, before any chroot, rather than closing - '-2' no longer swallows errors - '-A n' sets an alarm(2) for n seconds, or clears inherited alarm if n is zero - rlimit options accept '=', just like softlimit(8) - ./package/check (crudely) tests the new '-N' switch Perhaps better than the above: - man and html document previously undocumented '-r' and '-t' switches - man and html clarify that rlimit opts are soft limits, silently capped at the hard limit -Mike </pre> Mike Pomraning 2012-10-02T05:03:58 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2161 <pre>Issue: chpst sometimes displays its primary usage text when invoked as 'softlimit', which text is inappropriate for that utility.

Preserves complaints to standard error even under '-2' 2. Adds a '-N' ("null device") flag which modifies '-[012]' to redirect /dev/null with appropriate access modes, rather than merely closing fds 3. Documents #2 Rationale: #1 above helps me debug otherwise quiet ``chpst -2 /oops/enoent'' typographical errors. #2 guards against some programs' naive assumptions about the availability and nature of fds 0, 1 and 2. Implementation notes: The '-N' flag redirects before chroot, and respects the improved semantics of '-2' (that is, chpst can still complain of exec failures). Unmodified '-[012]' are now implemented with close-on-exec rather than close(). Other than the possibility of new complaints to stderr under '-2', the patch is behaviorally backward compatible. Let me know if you think this is wrong-headed. -Mike </pre> Mike Pomraning 2012-09-27T20:58:11 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2149 <pre>Hi, I am trying to write a python script which can be put in place of svlogd/multilog, but I am stuck just at the beginning. The test script is pretty simple, it just forwards stdin to stdout: def main(): while True: try: line = raw_input() print 'got', line except EOFError: print 'done' pass if __name__ == '__main__': main() It works, but not as desired, as the script is being restarted by runsv constantly, it seems after it finishes reading stdin. Could you please help me how can run that continuously listening to stdin? cheers, Serge </pre> Sergiusz Pawlowicz 2012-09-20T23:35:23 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2147 <pre>Hi laurent, I did a build of s6 with special slashpackages path. I succeeded to build and install on filesystem the result. But in using binary s6-ftrig-listen1, it complains about /command/s6-ftrigrd which is link missing even if the link target exists. Could you confirm that please?? Many thanks.

Is it used to supervise daemons that stubbornly fork into the background. Could anyone please explain with an example, i would be really helpful.

Thank you, Harish </pre> harish badrinath 2012-04-26T15:15:28 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2130 <pre>I have an application that scans log files that is written in Ruby. It is installed as the user log_watcher but needs to be run as root so that it can have the rights to read the various log files that it needs. Essentially the service/log_watcher/run file comes down to "sudo ruby log_watcher.rb", the log_watcher user has passwordless sudo rights. We have runit / supervise installed but when we try and start the application it complains about supervise/ok or supervise/lock being unavailable which means that the process is not being restarted after a reboot. How do I get to run the process as root from the log_watcher user. I've tried various things I've seen in the wiki and got back from googling but nothing seems to work. Or perhaps there is another way around this? </pre> Peter Hickman 2012-04-25T10:20:41 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2127 <pre>Announcing the latest release of perp, a persistent process supervisor: http://b0llix.net/perp/distfiles/perp-2.05.tar.gz What's New: * a couple of bugfixes for bigfuxes! * enhanced runuid(8) utility! * bigger release number!

For each user in the "svusers" group it starts a service manager in their ~/.sv directory. The service manager runs as that user, so as long as they can run the sv program, they can manage their own services. Per-user service managers run independently of user logins. I've released this under the BSD license, and it's available on github. https://github.com/eichlan/usersv I hope you find this program useful, I know I have. --Mike Buland </pre> Mike Buland 2011-10-20T16:26:17 http://comments.gmane.org/gmane.comp.sysutils.supervision.general/2111 <pre> s6-0.14 is out. This release fixes a bug that caused a SIGPIPE handler to not be properly reset after a call to ftrigw_notify(). (The bug was introduced by the sig_restore() semantics change in skalibs-1.0.3, which was a good thing, but ftrigw_notify() relied on the old semantics.) Sorry about that. http://www.skarnet.org/software/s6/ Enjoy.
