Re: [ptp-dev] launching remote proxy script
|
I did some testing to locate the problem:
Say, I have a script in /Users/fwang2/tmp/test.rb, which load an
external module file, mylib.rb.
To launch this in Java world:
try {
ProcessBuilder pb = new ProcessBuilder("/Users/fwang2/tmp/test.rb");
Process p = pb.start();
...
}
This will reproduce the error I saw earlier. I tried two ways to fix
this, first in Ruby script itself, I tried to ask it to look at current
directory for any external file, which is actually the default behavior,
doesn't work; Append an explicit loading path, doesn't work either,
which is a bit strange.
The second way is to make slight modification on Java launch: After
ProcessBuilder instance "pb" is created, change the working directory to
where the main program gets started:
pb.directory(new File("/Users/fwang2/tmp"));
Now the LoadError is gone. I am guessing the current launch process
ignores where the executable is, and take user's home directory as its
working directory. Is it so?

I guess the issue is how ruby finds the libraries that it needs. If it's
just looking in the current working directory, then this could be the
problem. There's no guarantee that the cwd is the same as the location
of the executable. Is there some way to specify where to look?

MOAB@Local: from

proxylib.rb is a local file residing in the same directory as
ptp_moab_proxy.rb. This seems to be the case for every file I try to
load at runtime.

Do you mean RSE launching onto local host, or using the Local service
provider?
What is the error message?

Hmm ... problem is, It gave me this error even with a local launch,
without ssh involvement.

No, but I haven't tried it with the remote support. Remember that
when you run a command via ssh, it will not load your .profile,
.bash_profile, .login, etc.). Any environment variables that need
to be set up have to be done in your rc file (.bashrc, .cshrc, etc.)

hi, Greg -
I have a remote proxy (a ruby script) that implemented wire
protocol 2.0. If I run the script in manual mode, then all is
fine; if in auto mode, then there is error complaining about
failing to locate certain files, be it a library file or my own
module file. In python world, this would be like when you do
"import certain_module", and the interpreter complains that there
is error with the file you are trying to import.
I suspect this has to do with some environment setup, without
looking into the specifics, when you worked on proxy for MPICH,
have you experienced anything similar?
Thanks
