I dream of easier merge conflict resolution on GitHub Pull Requests


It's currently a bit of a hassle (unless I'm doing it wrong) to fix a PR that used to be green but is now unmergeable due to an simple little merge conflict with master.

It would be quite fantabulous if I could access the swanky invisible PR branches from the web interface in order to quickly fix the merge conflict and merge/close the PR without having to:

  • ask & wait for the submitter to fix a conflict they might not understand better than I do (since master likely caused it if the branch is green)
  • tediously add the submitter's repo as a remote and pull their branch, merge master in it to fix the conflict and either submit a PR to their fork or merge it into master directly (which sadly by-passes the existing PR)
  • do the local PR checkout trick (but I'm lazy, don't make me do it!)

A dream solution that would make GitHub even more addictive would be an interactive conflict resolutio

Protip: Bisecting a single commit
View gist:0fa021df52a3bd2485ac

Situation: Some commit (on master, but not necessarily head of master) has broken things, but it's a big commit and it's not clear what part broke things.

% git checkout master
% git checkout -b bisect-branch
% git revert <offending commit>

(test here to make sure reverting fixed your problem)

Hi David
I'm impressed with your back ground and your responsibilities at 37signals. When researching your profile I also found that you have 4.8K followers and have been starred 29 times on GitHub. This speaks volumes to your work and your high technical expertise. I'd love the opportunity to speak with you about a Ruby Engineering role I'm currently working on for Heroku. I'd like to share more details about the position and find out if you or anyone you know would be interested.
Heroku is a Platform as a Service (PaaS) that lets you deploy, run and manage applications written in Ruby, Node.js, Java, Python, Clojure and Scala. Heroku is owned by Salesforce however, we operate as a completely separate entity. This allows us to maintain our technology, culture and the formula that has made us so successful.
Anyway, it would be great to set up sometime to chat. I am more than happy to answer any questions that you might have and it would be great for me to hear about what you are looking for in any potentia
