​
Summary:
Egg cartons only hold a maximum of 12 eggs. The app fataled when there are more than 12 eggs.
​
We shouldn't store more than 12 eggs in a carton.
​
We also were able to improve the algorithms to better insert eggs.

Commit Messages

Write for clarity.
Write knowing that it will be read later.
Convey intention.
Convey purpose.
The purposes of the commit message is to convey to the reviewer, or someone who has to debug or understand your code in the future, why did we have to write this diff?

Pros

  • Speeds up code review process.
  • Becomes most recent up to date documentation.
  • Reduces context switching to other systems.
  • Helps future maintainers of the repository.
  • Extremely helpful for people who have to read alot of code.
  • Aids in debugging.

Commit Message

Commit messages consist of at least three things:
  • One Line Summary
  • Summary
  • Test Plan
Optional (depending on project):
  • Task
  • Additional URLs
  • Reviewers
  • Reviewed By
  • Deployment Process

Structure

One Line Summary

Contains succinct description of the change.
  • Keep this short and sweet. Less than 50 characters.
  • Don't make it too generic. For example: "New Unit Test" is bad because it doesn't describe what the unit test does.
  • Quick way to reference the diff.
  • Use the imperative, present tense: "change" not "changed" nor "changes"
  • No dot (.) at the end
Semantic Release
Adapted from Angular:
Types:
  • build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
  • ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
  • config: Changes to any configurations.
  • docs: Documentation only changes
  • feature: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that neither fixes a bug nor adds a feature
  • revert: The summary of the commit that was reverted
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • test: Adding missing tests or correcting existing tests
  • typos: Fixing typos in flavor text
  • ux: Improvements to User Experiences (ie: changes to color)
    • Not to be confused with ui.
    • Using ux to emphasis the impact of the ui

Summary

Describe in detail:
  • why this diff necessary
  • what are the trade offs of your decisions
if its a new feature:
  • why do we want to add this feature
  • expected result of releasing the feature
if refactoring code
  • why are you refactoring the code
  • what bash commands you used to find/change the code
if its a bug fix:
  • what is expected to happen
  • what actually happened
  • how the bug was discovered
  • how long the bug was live for
  • what commit/diff caused the bug
  • how the bug was fixed
  • severity of the bug
    • people/services effected
    • amount of downtime
    • link to charts displaying severity
    • screenshots of severity
if there is a performance improvement
  • give comparison of before/after. For example:
    • how many milliseconds did it take before/after
    • how much memory does it take before/after

Test Plan

Test plans are used:
  • Reviewers know that you have tested throughly.
  • When having to understand old code, you know how to test it thoroughly.
Always try to make the test plan as easy to reproduce as possible. If a test plan is too long, this could potentially be a sign that what you are implementing is too complex.
Include:
  • screenshots (if its a ui change)
  • URIs of the pages effected
  • any shell commands that were executed
  • any configuration changes that are needed

Additional URLs

Paste any additional relevant URLs, for example URLs to:
  • Asana
  • GitHub Wikis/Issues
  • Google Docs
  • Internal Tools
  • JIRA
  • Kabanize
  • Travis
  • Wiki Pages
This makes it easy to reference them. Try to use the canonical url when possible.

Deployment Process

  • How do we deploy this version of the code?
  • How can we monitor the deployments?
  • What alerts can be received?
  • Where can someone receive alerts?
