Re: Error using cygrunsrv to stop bash scripts

[Cousins, Andrew]

Igor,

Service is installed with

#
cygrunsrv   --install actest3                      	 	\
                --path c:/usr/Cyg-Win32/bin/bash.exe   	\
                --args d:/usr/ea/dr_service/actest.sh 		\
                --desc "MOSAIC/DNMS Disaster Recovery"  	\
                --type manual                          		\
                --neverexits                            		\
                --shutdown

The log files put out a single line .. Terminated.... each time the service
is stopped

Putting a cygcheck -svr in the service script and redirecting output to a
file I get this with the last line (code 5)  repeated a few times before the
Terminated Message.

cygcheck: dump_sysinfo: GetVolumeInformation() failed: 67
cygcheck: dump_sysinfo: GetVolumeInformation() failed: 67
cygcheck: dump_sysinfo: GetVolumeInformation() failed: 5
....
....
Terminated

Putting 
	env >> tempfile 
doesn't produce anything from within the service.

Looks like it's only stderr being generated from within the service as there
is none of the additional info I get from these two commands when it is run
interactively.

Tried the INT signal, same symptons. Does what I want, but displays the
error messages.

I'm not Windows enabled - how would I run this interactively under a SYSTEM
owned sh.

Thanks

Andrew C.

There should be *one* log file, /var/log/actest3.log.  Which ones are you
looking at?  Try explicitly specifying it using the "-1" and "-2"
cygrunsrv options.  Also, what does the Windows Event log show
(on Win2k, right-click on "My Computer", choose "Manage", then "Event
Viewer"->Application).

I'd suspect something wrong with your mounts (e.g., they aren't system
mounts), or directory permissions.  The output of "cygcheck -svr" from a
regular shell would have been very helpful (and it *is* requested in the
Cygwin problem reporting guidelines at <http://cygwin.com/problems.html>,
which you should read in any case).

Which probably means that the service runs with an empty environment...
Unless...  Try specifying /bin/env explicitly, just in case, as well as
the full path to the tempfile.  Putting 'echo "$PATH" >&2' into the bash
script might also be helpful.

Did you try trapping SIGINT in the bash script and printing out a message
before exiting?

Googling for "system-owned window cygwin" should give you a couple of
recipes.

Andrew,

What exact command are you using to install the service?  Does
/var/log/<svc_name>.log show anything?  Does the script run and terminate
OK from a SYSTEM-owned shell?  What is the environment that the script
runs under ("env >> /tmp/svc_env", or, even better, "cygcheck -svr >
/tmp/svc_cygcheck.out")?  Did you try using another signal for service
termination?

Error using cygrunsrv to stop bash scripts

[Cousins, Andrew]

I have installed cygrunsrv to run bash.exe with a script as parameter.
Service starts and stops OK but on the stop
it also produces these errors. .

A system error has occurred.
System error 1067 has occurred.
The process terminated unexpectedly.

Script does catch the signal and terminate gracefully and it also
 runs OK from command line and can be terminated properly with a TERM
signal.

Help in what is causing the errors would be appreciated.
