Wrong exit code on success

[dcharbonnier]

# pm2 delete all && echo "OK" || echo "NOK"
PM2 Stopping and deleting all processes
No processes launched
NOK

Just to anticipate a possible troll

git checkout develop && echo "OK" || echo "NOK"
Already on 'develop'
Your branch is up-to-date with 'origin/develop'.
OK

I'm seeing the same issue. We use Rundeck (http://rundeck.org/) for automated deployments and the incorrect exit code causes remote scripts to hang.

It looks like this may duplicate issue #235.

Your process isn't launched so pm2 failed deleting it. Normal behavior...

@divThis in the https://github.com/Unitech/pm2/blob/master/lib/CLI.js file you can notice that there is a cst.SUCCESS_EXIT = 0 code that is returning when exiting.

I'll take a look at rundeck though, interesting.

A solution might be to check if the process is alive before executing the delete command.

[dcharbonnier]

this is not the issue, the process IS launched.

pm2 ping; pm2 delete all && echo "OK" || echo "NOK"
{ msg: 'pong' }
PM2 Stopping and deleting all processes
No processes launched
NOK

you launch a command, you get the expected result and the command tell you there was an error

[dcharbonnier]

@divThis you can do that ...

#!/bin/sh
RES=pm2 delete all 2>&1 >/dev/null;
EXIT_CODE=$?;
if [ $EXIT_CODE -ne 0 ];then
if [ "x$RES" = "xNo processes launched" ]; then
EXIT_CODE=0;
fi;
fi;
exit $EXIT_CODE;

... and if you launch this command twice you will get OK and then NOK ;-)

[soyuka]

Yes then the process is deleted, it no longer exists

[dcharbonnier]

No, ping start the pm2 process... can you just do this and paste result ?

pm2 ping; pm2 delete all && echo "OK" || echo "NOK" 

pm2 ping; pm2 delete all && echo "OK" || echo "NOK" 

[soyuka]

pm2 ping doesn't start anything, it just give a pong message if pm2 is started, (if not it launches it). It does not start or check instances.

pm2 delete all on the other hand is removing all processes from the pm2 list so if you'd want to start one again you'd have to use pm2 start index.js

Maybe that you're looking for pm2 dump and pm2 resurrect commands.
