While I was able to read/clone a git repository self-hosted with HTTPD and git-http-backend, I found that I could not push to it. Here’s how I fixed it.

Deploying a Minimalistic Flask Application to OpenShift
Some colleagues and I were discussing the network access policy of OpenShift. I realized it would be very helpful to have a trivial app that I could deploy to OpenShift that would then try to make a call to another service. So I wrote it using Python3 and Flask. Now that I have it working, I want to deploy it in OpenShift, again, in a trivial manner.
I would not deploy a Flask App into production without a Web server to front it. But that is what I am going to do for this test app.

“Let the complexity emerge.” Probably the best advice I ever got in coding. Do something in as straight-forward manner as possible. When you find your self repeating code, extract it. Here’s an example from an ansible playbook I’m working on.

DevOps requires that everything goes into Revision Control. CloudForms’ modifications are no exception. But how do you revision control something that is managed by a GUI and stored in a database? Import and export with the command line. Here’s how.
Oh No! I Committed to master! What do I do?
You were working in a git repo and you committed your change to master. Happens all the time. Panic not.

Amending a patch in git
From a co-worker:
amend is new to me… will the updated patch be a full patch to the original source or a patch to the previous patch?
Here’s how I explain it.

Splitting a patch
To make things easier for your code reviewer, each patch should be small, and hold one well defined change. I break this rule all the time, and it comes back to bite me. What happens is that I get heads down coding, and I have a solution that involves changes to wide number of files and subsystems, new abstractions, etc. Here is how I am currently dealing with breaking down a big patch.
A SQL upgrade script in Keystone
The SQL migration mechanism in Keystone is interesting enough to warrant some attention. If you need to modify the SQL database in any of the Open Stack projects, you are going to use a similar approach. Here is a step by step I have recorded of a SQL upgrade script I am writing for a feature in Keystone.

What changed in that latest patch?
Gerrit is great, but one thing it does not do well is tell you the differences in an update to a review request. Here’s how I found I could focus review requests to just the deltas between submissions.

Keeping Development Code Current
Embracing change is hard. Accepting criticism on code you worked so hard to prepare for review can be hard on the ego. But when you have additional work that is underway that depends on submissions undergoing review, it can also be a challenge to your organizational skills. I’ve recently learned a trick about git that makes this easier in the context of Open Stack development.
