Error creating a python project

[srobertson]

Slug compilation fails when creating a python project.

How to reproduce:

$ mkdir myproject
$ cd myproject
$ git init
$ ~/openruko/client/openruko create
$ echo boto > requirements.txt
$ git add -A
$ git commit -m "initial commit"
$ git push heroku master

I wouldn't be surprised if this turns out to be a problem in Codonhooks or Dynohost.

Gitmouth should probably have a well defined interface and set of
expectations to avoid misfiled issues. I recommend following the interface
created by gitreceive [1] ;)

I'm also interested in trying out OpenRoku for deploying Python/Django apps. Any luck resolving this issue?

Once I have some free time, I will take a look at it.

Hacking around, I was actually able to get the python build pack to
successfully compile the slug. However I broke other things. But at least
my debug info might help.

First off this issue probably needs to be moved to apiserver/codon hooks as
I think these will be the modules that need to be updated. gitmouth has no
issues as far as I can tell.

The problem is because the heroku python buildpack actually moves all the
contents of /app to a temporary directory when compiling the slug. See
https://github.com/heroku/heroku-buildpack-python/blob/master/bin/compile#L48

Codonhooks treats /app as the root of the git repository when it's
receiving the push, due to the above mentioned move it corrupts the git
repository and hence you receive these errors when you git push

As an experiment I modified
apiserver:postgres/openruko_api/functions/handle_git_command.pgsql
to mount the empty repo under /tmp/repo and then tweaked codon hooks to
mount it's hooks under /tmp/repo/hooks rather than /app/hooks

Making those changes, fixed slug compilation. However actually dyno startup
fails now for reasons I have not tracked down yet.

That's as far as I got before I ran out of time. Hopefully this helps
someone else who's more familiar with openruko internals.

Thanks for sharing. It will helps

[natea]

@srobertson did you submit that patch as a pull request?

[srobertson]

@natea I hadn't until now.

Here are the changes I made

openruko/apiserver#28
openruko/dynohost#17

Keep in mind, I was only trying to debug the problem, I wouldn't accept those patches "as is"

[Filirom1]

Ok so it seems that /tmp/repo is needed for slug compilation but /app is needed for running the dyno.

Thanks for the pull requests. It´s quite easy now to fix it
