Eli Barzilay commented on DERBY-6925:
-------------------------------------
1. Yes, I haven't seen that file distributed, but I have seen its
contents in other places (IIIRC, it was in the start script version
for linux).
2. To see the failure, try
expr $foo : '.*sh.exe$'
and you'll get a syntax error since $foo doesn't exist; but if you
quote it:
expr "$foo" : '.*sh.exe$'
it works fine whether it exists or not. It's true that the chances
of $SHELL not being set are small, but in a docker environment that's
exactly what I ran into...
> Bug in derby_common.sh
> ----------------------
>
> Key: DERBY-6925
> URL: https://issues.apache.org/jira/browse/DERBY-6925
> Project: Derby
> Issue Type: Bug
> Reporter: Eli Barzilay
> Priority: Minor
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> At the end of the `derby_common.sh` file, as I currently see in the GH
> mirror:
>
> https://github.com/apache/derby/blob/trunk/bin/templates/derby_common.sh#L166
> there is an unquoted use of $SHELL which should really be quoted. We
> have run into this bug trying to start the server in a docker image,
> with a setup that has no SHELL variable, which results in a syntax
> error.
