I've been having issues using Phabricator to create a patch for hive. It looks like some versioning issues with arc_jira_lib and libphutil.
I kept getting this error: "libphutil v1 libraries are no longer supported."
To work around it go to the libphutil directory you checked out of git and revert to an older commit:
git checkout 870bcc76434410344d27a3fa4604ac96200bf7f6
The next problem is the arc client:
ERR-BAD-VERSION: Your 'arc' client version is '6', which is newer than the server version, '5'. Upgrade your Phabricator install.
So also get an older version:
git checkout 6cb8d483b23c132da4c82934438cd1af0e5ba32b
I'll leave the actual fixing to someone with a bit more php experience.
After that I tried to "arc diff HIVE-3308" added the message then:
LINT OKAY No lint problems.
Running unit tests...
No unit test engine is configured for this project.
Usage Exception: There are no changes to generate a diff from!
In the end I manually uploaded It as D8187. And added the patch to Jira even tough I guess that's what arc is suppose to do.
