Cannot identify HEAD for git repository.

[Fajkowsky]

I have
django 1.8
python 3.5
raven 5.26.0
And I have followed django integration after executing:

python3 projectname/manage.py raven test

I have got
raven.exceptions.InvalidGitRepository: Cannot identify HEAD for git repository at /home/faja/Pulpit/Projekty/mainProjectFolder/djangoFolder/mainAppWithSettings

I think it's a documentation issue. I followed the quick installation instructions on my sentry instance, which suggests this line

'release': raven.fetch_git_sha(os.path.dirname(__file__)),

in your settings.py. But if your settings.py is like mine one folder down from your git root folder, then you get the error you describe (because of this: https://github.com/getsentry/raven-python/blob/master/raven/versioning.py#L22). Instead follow https://docs.sentry.io/clients/python/integrations/django/ and replace the line with:

'release': raven.fetch_git_sha(os.path.dirname(os.pardir)),

and you're in business!

I was stupid, I had bad path set to git repo root, now all works well, thx :)

[megha-n-bodke]

git repo root should be specified in raven.fetch_git_sha().
Below line can be used to test the path value. For incorrect path, it will return above reported error.
python -c 'import raven; raven.fetch_git_sha("../../")

I think, we can close this issue :)

@Fajkowsky @megha-n-bodke - We're having this issue on Heroku despite the updated release path.

That won't work on heroku.

As of July 18th, 2017:

• The git information isn't there
• You have to grab the SOURCE_VERSION environmental variable during builds (https://devcenter.heroku.com/changelog-items/630)
• But heroku disregards that during actual running service

So:

1. Use this buildpack to keep the SOURCE_VERSION in your deployments

   $ heroku buildpacks:add https://github.com/ianpurvis/heroku-buildpack-version (https://elements.heroku.com/buildpacks/ianpurvis/heroku-buildpack-version)

2. Then do this in your settings:

RAVEN_CONFIG = {
    # 'dsn': 'https://....',
    'release': os.environ['SOURCE_VERSION']
}

There is also this feature which should be helpful:

https://devcenter.heroku.com/articles/dyno-metadata

make sure path is correct. try to use os.path.dirname to go one level up the directory.

I have tried all of the above and it didn't work for a Django Project I have been working on. We're using Heroku also if that is relavant. What eventually worked for me is:

'release': raven.fetch_git_sha(os.path.abspath(BASE_DIR)),

Where BASE_DIR is set in the settings file which resides in the project folder one level up from the root of the project. The project settings file is specified using an environmental variable:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

Hope this helps anyone else with a similar problem

[dcramer]

You can simply enable the dyno metadata in heroku labs, as the repo they ship might have metadata stripped:

'release': raven.fetch_git_sha(os.path.dirname(os.pardir)), works fine on my local
But when I deploy my Django app to AWS EC2. I use docker container and I copy only source code.
How can I use it without .git?
