Igor Ostapenko commented on TINKERPOP-2685:
-------------------------------------------
Well, I've tried to trace it and I've found that in my case this line works not
as expected, it yields true and steps into the if block:
[https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/bin/gremlin-server.sh#L74]
As a result it makes it worse, i.e.
GREMLIN_YAML=/opt/gremlin-server//opt/gremlin-server/conf/gremlin-server.yaml.
This is unexpected branch of logic what, obviously, ends up with server start
error.
The next question for me is why test -r works wrong way for 3.5.1, but it works
fine for 3.5.0.
3.5.0:
{code:java}
# let's use /bin/bash as bin/gremlin-server.sh does
> docker run --rm -it --entrypoint '' tinkerpop/gremlin-server:3.5.0 /bin/bash
bash-5.0$ pwd
/opt/gremlin-server
bash-5.0$ test -r conf/gremlin-server.yaml ; echo $?
0{code}
3.5.1:
{code:java}
> docker run --rm -it --entrypoint '' tinkerpop/gremlin-server:3.5.1 /bin/bash
bash-5.1$ pwd
/opt/gremlin-server
bash-5.1$ test -r conf/gremlin-server.yaml ; echo $?
1
bash-5.1$ head -n2 conf/gremlin-server.yaml

> $ docker run tinkerpop/gremlin-server:3.5.1
