Frequently asked questions

Is self-hosted Github Enterprise supported?

Unfortunately we don’t yet support self-hosted Github Enterprise instances.
Github marketplace apps can’t be installed on self-hosted Github instances. Apps for these instances require a complex setup involving creating a new app on the self-hosted instance with all the same permissions and webhook configuration as the app found in the Github Marketplace.
The app’s code needs to be told the url of the self-hosted Github instance and is then run in either a container on the privately hosted machine, or it runs in the cloud (like the marketplace app) and is allowed to connect to the private server.
Both options involve complexity that we have decided not to undertake yet. We apologize to anyone who’s affected by this and hope to have a solution some time in the future.

When I try and subscribe to a paid plan all I see is “Unfortunately, invoiced customers cannot purchase paid plans on the Github Marketplace.”

If an invoiced Github account tries to sign up for a subscription to Merge Freeze via the Github marketplace they are sadly met with the following message: “Unfortunately, invoiced customers cannot purchase paid plans on the Github Marketplace.”
We offer payment via Stripe for these customers. In order to do this you’ll need to first sign up to the Open source plan (which is free). Then email [email protected] and let us know the name of your organization, which plan you’d like to subscribe to, and whether you’d like to pay monthly or yearly.
We’ll manually change the plan for your account and send you a link to start payments via a Stripe payment form (with a 2 week free trial). To cancel or change the plan you’ll need to email us.

How do I fix a pull request that has a Merge Freeze status check that’s stuck on pending?

If a pull request is created or updated in Github it will send Merge Freeze a webhook. Merge Freeze then tries to find the current status of the relevant project (frozen or unfrozen) and sends the pull request a status update via the Github API.
If a network error occurs so that the webhook never reaches Merge Freeze, or some other error occurs so that the status update doesn’t make it to Github then the Merge Freeze status can be left in a “pending” state with a message that says something like “Expected - Waiting for status to be received”.
To fix this you can either send an update to your pull request so that it triggers another webhook, or you can force Merge Freeze to send another status update to all open pull requests by toggling a freeze off and on again.
New commits can be made to a repository without having to make code changes using the --allow-empty flag e.g.
1
git commit --allow-empty -m "Trigger update"
Copied!

Merge Freeze no longer updates the status of my pull request

It turns out that no single commit id can be given more than 1000 status updates from the same context (you can consider Merge Freeze to be a context). So if you have an old pull request that has been sitting there without any new commits it’s possible with many freezes and unfreezes that this limit is hit.
To fix this you’ll need to send a new commit to the pull request. New commits can be made to a repository without having to make code changes using the --allow-empty flag e.g.
1
git commit --allow-empty -m "Trigger update"
Copied!

Why does it take so long for all PRs to get updated when freezing / unfreezing?

If you’re using the default “Push a status update to all PRs” method of freezing then every time a project is frozen or unfrozen we need to make an API call to every open pull request.
These updates must be done serially, according to Github's app rules. If you have many open pull requests it may take some time to update them all (roughly one second per pull request).
If you have many pull requests that need updating you may wish to switch to the “Toggle a branch protection rule” method of freezing. This can be done in a project’s settings under “Freeze method”.

How come people can still merge even though I have frozen my project?

By default Github will still let you merge even when status checks fail:
To block merging completely: In your Github repository head to Settings -> Branches -> Protected branches and choose the branch that you'd like to be able to freeze (e.g. master).
  • Check Protect this branch.
  • Check Require status checks to pass before merging.
  • Under Status checks found in the last week for this repository check mergefreeze.
  • Optionally check Include administrators if you want admins to obey the rules too.
  • Click Save changes
Now when the branch is frozen users will not be able to merge:

Do I need to invite other users to my Merge Freeze project?

You don’t need to specifically invite users to your Merge Freeze project to allow them to freeze / unfreeze projects.
Merge Freeze uses Github’s permissions system to decide which projects a user should have access to. It does this by using the Github API to fetch all repositories that have the Merge Freeze app installed and that the user is a member of. These will automatically show in the user’s Merge Freeze control panel when they login.

I want to freeze / unfreeze all of my repositories at the same time

Many customers would like the ability to freeze and unfreeze a group of repositories at the same time.
We haven’t implemented this yet and the main reason is performance. Since Github only allows one update per second for each open pull request this could lead to very long update times if someone was to try and update all pull requests in every repository their organization has.
There are obviously scenarios where it wouldn’t be too much of a problem e.g. a small number of repositories each with a small number or pull requests, and there are technical solutions that could involve encouraging the use of the “Toggle a branch protection rule” method of freezing, but unfortunately we haven’t been able to implement any solutions for this yet.
In the meantime another potential option is to use the Merge Freeze API with an organization level access token to loop through each of your repos and freeze them, just bear in mind that a rate-limit applies.
