How to view remote Git revision on Heroku

For deploying to Heroku, I use git push heroku master. But how do I see which revision I pushed up to heroku? (I'm often in doubt if I pushed the recent version up)

For those not familiar with it, Heroku's create script generates a remote git repository that you push to. Upon push, the code is deployed magically.

Heroku adds a remote repository to the local one in the form:

$ git remote add heroku git@heroku.com:appname.git

More info in Heroku's manual "Deploying with Git"

Question is: How can I see latest version in Heroku repository?

git-remote heroku git

If you've just pushed and want to make sure you're up-to-date, then you can just run git remote show heroku and you'll see output similar to this:

* remote heroku
  Fetch URL: git@heroku.com:XXX.git
  Push  URL: git@heroku.com:XXX.git
  HEAD branch: master
  Remote branch:
    master tracked
  Local ref configured for 'git push':
    master pushes to master (up to date)

That (up to date) at the end will be replaced by (fast forwardable) if it is not up to date.

Or, if you're wanting to see the full commit log for the heroku remote, the only way I know how is to check it out first. git checkout heroku/master will give you the current commit hash and commit comment: HEAD is now at <short commit hash>... <commit comment>, and git log will give you the rest of the story.

if you've run into the situation, like i just did, where a co-worker rolled back your heroku app to a release that doesn't show in heroku releases because they only keep track of 2 releases... the checkout of heroku/master method won't help, because HEAD is not what is deployed anymore.

the undocumented to the rescue:

$ heroku console "ENV['COMMIT_HASH']"
"12abcdef"
