# Sensitive Release Protocol
|
|
|
|
In the case that a new change is so dramatic that it is hard to anticipate all of the potential side-effects, here is a protocol for rolling out these sensitive changes in a way that:
|
|
|
|
- Minimizes adverse impact on end users.
|
|
- Maximizes our responsiveness to these changes.
|
|
|
|
## Protocol Steps
|
|
|
|
1. Prepare a normal release.
|
|
2. Prepare a rollback release.
|
|
3. Roll the normal release out.
|
|
4. In case of emergency, roll back.
|
|
|
|
### Normal Release
|
|
|
|
Simply follow the steps in [the publishing guide](./publishing.md).
|
|
|
|
### Prepare Rollback Release
|
|
|
|
Follow the steps in [the publishing guide](./publishing.md) with a different context:
|
|
|
|
Instead of creating a version branch off of the main branch, create a version branch off of the latest release. It is customary that this release increments the patch version number.
|
|
|
|
### Roll the normal release out
|
|
|
|
Ensure the rollback release has been built, and downloaded locally, fully ready to deploy with immediacy.
|
|
|
|
For a sensitive release, initially roll out to only 1% of Chrome users (since Chrome allows incremental rollout).
|
|
|
|
Monitor Sentry for any recognizable error logs.
|
|
|
|
Gradually increase the rollout percentage.
|
|
|
|
### In case of Emergency
|
|
|
|
If a problem is detected, publish the roll-back release to 100% of users, identify the issue, fix it, and repeat this process with a new release.
|
|
|
|
## Summary
|
|
|
|
This protocol is a worst-case scenario, just a way to be incredibly careful about our most sensitive possible changes.
