In case you, like me, were wondering what drake is: https://github.com/Factual/drake

Drake is a simple-to-use, extensible, text-based data workflow tool that organizes command execution around data and its dependencies.

I'm not a drip expert, but I suspect @ninjudd will want to see the output of drip ps. That should output some stuff, including a directory; a sibling of that directory should be an opts file, whose contents will probably also be useful.

As you might have guessed, no background JVMs are started:

artem:~/drake$ drip kill
artem:~/drake$ drip ps
artem:~/drake$ drip kill
No idle Drip JVM running

So it looks like drake is looking for a workflow file, not finding it, and
then bailing. The background jvm does the same thing as soon as it starts
up, and thus also exits before you have a chance to use it for anything.

I don't understand.
How is that different from my Clojure example which starts up, prints "Hai", and then bails?

amalloy commented

You're right, it's not. We've figured out the problem and are working on a fix.

ninjudd commented

The problem was that drip was assuming that DRIP_INIT_CLASS should be the same as your main class if you didn't set DRIP_INIT_CLASS. This meant that drip was trying to call your main function at startup before anyone connected to the spare jvm, which in this case was causing it to exit immediately.

I have released 0.2.0 with a fix.

aboytsov commented

Thank you!

Is it possible to release a new brew version? So far I get:

artem:~$ brew upgrade drip
Warning: It appears you have MacPorts or Fink installed.

alza-bitz commented

Don't want to spoil the party, but I am getting what looks to be the same problem, using the same commands to test, with the latest versions of both Drip and Drake:

[alex@spica drip-test]$ drip version
drip version "0.2.5" checkout 917e189
[alex@spica drip-test]$ drake --version
Drake Version 0.1.6

I built both from git source, Drip git #917e189, Drake git #2f44a8b.

Any ideas?

Thanks :)
