-------------------------------------

             Summary: [Dev] Merge script imposes directory name
                 Key: ARROW-5146
                 URL: https://issues.apache.org/jira/browse/ARROW-5146
             Project: Apache Arrow
          Issue Type: Bug
          Components: Developer Tools
    Affects Versions: 0.13.0
            Reporter: Antoine Pitrou


The merge script currently fails with a cryptic message if the parent directory isn't named "arrow":

{code}
$ ./dev/merge_arrow_pr.py 
ARROW_HOME = /home/antoine/arrow/dev
PROJECT_NAME = dev
Which pull request would you like to merge? (e.g. 34): 4113
url = 'https://api.github.com/repos/apache/dev/pulls/4113'
{'documentation_url': 'https://developer.github.com/v3/pulls/#get-a-single-pull-request',
 'message': 'Not Found'}
Traceback (most recent call last):
  File "./dev/merge_arrow_pr.py", line 462, in <module>
    cli()
  File "./dev/merge_arrow_pr.py", line 417, in cli
    pr = PullRequest(cmd, github_api, git_remote, jira_con, pr_num)
  File "./dev/merge_arrow_pr.py", line 252, in __init__
    self.url = self._pr_data["url"]
KeyError: 'url'
{code}

PROJECT_HOME is inferred from the current directory name, though it should almost always be "arrow".
