Hi,
I don’t know if is useful in your case, but you made me remember I made
a small tool to trap unix signals within Pharo. I uploaded then to github.
https://github.com/estebanlm/pharo-posix-signal
is very easy to use and it will allow you to trap any signal and do what
you want ;)
Not as easy as it seems, ran this on docker image herbysk/pharo:64_61
(based on the one from that day Iceberg was backported):
========================================================================
root@2367caef3dac:/# cat s.st

Iceberg enableMetacelloIntegration: true; remoteTypeSelector: #httpsUrl.

repository: 'github://estebanlm/pharo-posix-signal/src';
baseline: 'POSIXSignal';
load.
trap := POSIXSignal SIGINT. trap installWith: [ :signal | 'Trapped!!'
crLog ].
trap := POSIXSignal SIGTERM. trap installWith: [ :signal | 'TERM!!'
crLog ].
root@2367caef3dac:/# pharo /opt/pharo/Pharo.image ${PWD}/s.st --no-quit
pthread_setschedparam failed: Operation not permitted
This VM uses a separate heartbeat thread to update its internal clock
and handle events. For best operation, this thread should run at a
higher priority, however the VM was unable to change the priority. The
effect is that heavily loaded systems may experience some latency
issues. If this occurs, please create the appropriate configuration
file in /etc/security/limits.d/ as shown below:
cat <<END | sudo tee /etc/security/limits.d/pharo.conf
* hard rtprio 2
* soft rtprio 2
END
and report to the pharo mailing list whether this improves behaviour.
You will need to log out and log back in for the limits to take effect.
For more information please see
