Fix: Set correct branch when it's not specified in the config #5844

bytrangle · 2021-09-27T09:27:00Z

Summary
Currently, the default branch in Github, Gitlab and Bitbucket is set to be main instead of master.

However, when people use Netlify CMS and don't specify the branch name to push content in the config file, Netlify CMS will automatically push to branch master.

Since this branch may not exist, users will get an error on the frontend: "API_ERROR: Branch not found".

Test plan

In the admin/config.yml file, specify a valid Github repo path to push content to.
Run yarn start.
Go to Neltify CMS dashboard, create a new post and hit Publish. You shouldn't get an error. Checking back on the repo that you specified in the config, you should see the new post.

Checklist

Please add a x inside each checkbox:

I have read the contribution guidelines.
Code is formatted via running yarn format.
Tests are passing via running yarn test.
The status checks are successful (continuous integration). Those can be seen below.

Please hold off on reviewing until I've pushed the unit tests.

Thanks @bytrangle, great work as always.

I've added some comments, please let me know your thoughts.
Also, are we planning to do this for other backends too?

+      if (!masterBranch) {
+        // Get default branch of the repo
+        const defaultBranch = await this.api!.newGetDefaultBranch();
+        this.branch = defaultBranch || '';


Suggested change

this.branch = defaultBranch || '';

this.branch = defaultBranch || 'master';

Should we default to master to ensure the property is set (this will avoid calling setDefaultBranch again if authenticate is re-invoked).

Two things:

I didn't consider the scenario that authenticate can be revoked. I will change it as requested.Good point.

I was going to apply the same approach to other backend, but then I realized that would mean writing some repetitive code. That will open up more room for errors and make it harder to track changes in the future. So what do you think about adding a helper in Netlify Utils to get a default branch and call that in each respective backend?

2. Netlify Utils to get a default branch and call that in each respective backend?

Sounds good! How about adding the helpers to https://github.com/netlify/netlify-cms/blob/master/packages/netlify-cms-lib-util/src/backendUtil.ts?

Should it be backendUtils or API.ts is the place?
And when do you need these changes? I normally don't work on open source on weekend, but if you need it soon, I can work on this issue on Sunday.

Either backendUtils or API.ts work (or both) depending on the common logic you extract.

I normally don't work on open source on weekend, but if you need it soon, I can work on this issue on Sunday.

I definitely don't need it soon, and in any case no need to change your work schedule for us. We are the ones who should adjust our schedule to contributors.

Sorry that it took such a long time to update this PR. Writing a helper that can accommodate all the major git hosts turn out to be more complex than I had expected.

bytrangle · 2021-10-27T09:59:55Z

Hello @erezrokah . Let me ask a noob question: How do I rerun the Github action workflow? Or is it only possible for team members?

erezrokah · 2021-10-27T10:26:27Z

No noob questions - do you have this button when you open the action?

erezrokah · 2021-10-27T10:27:53Z

Regardless, I invited you to collaborate on the repo, long overdue ❤️

@bytrangle are you still interested in moving this forward?

paulRbr · 2024-02-28T09:55:49Z

I think this PR is interesting to be merged upstream. I was going to suggest a much more simple change (changing the default value of the branch to main) but I think this PR is better.

martinjagodic · 2024-02-28T11:53:08Z

@paulRbr yes, we would like to have this merged, but we need to solve those merge conflicts first.

bytrangle · 2024-03-14T13:00:49Z

@martinjagodic Hi, I'm interested in working on this again. However, I may have to ask you about resolving merging conflicts later :).

martinjagodic · 2024-03-14T13:03:15Z

@bytrangle awesome! The conflicts emerged when we renamed the packages from netlify-cms-* to decap-cms-*. If a rename does not suffice, I am happy to answer questions/help out.

bytrangle · 2024-04-01T10:08:00Z

Hi @demshy . Is there anything else I need to do?

demshy · 2024-04-02T07:04:26Z

Sorry @bytrangle I somehow overlooked this one. I added a missing import that made the unit tests fail. I will gladly merge this one into a release this week

+    baseHeaders['Authorization'] = `token ${token}`;


Hi @bytrangle, do you by any chance remember, why this is using token instead of Bearer here?
This seems to be causing an issue with Gitlab logins, since this PR was merged in April: #7172 (comment)

I'm not sure about Github/Bitbucket, but it seems at least for Gitlab this line should be like this:

Suggested change

baseHeaders['Authorization'] = `token ${token}`;

baseHeaders['Authorization'] = `Bearer ${token}`;

For reference: This line was originally introduced in 3edc3ce, this comment is on a2add4a, which was later squashed to c91a70f

I don't remember. This corresponds to Gitlab docs 13.0, which is no longer available. Please feel free to make a new PR to correct it.

Thanks anyway, I now created #7242 for this change.

Nice work @floscher

I cloned the decapCMS repo locally yesterday to double check the fix.

After adding the fix and rebuilding decapCMS, I no longer got the previous error message.

However, I then still got an "API_ERROR: Branch not found" message, implying that the code this patch was meant to fix doesn't do it's job on gitlab anyway..

Only after hard-coding "branch: main" into my config.yml, was I then able to get on with things.

…Bearer" (decaporg#7242) The authorization type "Bearer" is more widely recognized than "token". E.g. Gitlab requires that you use "Bearer". This should fix decaporg#7172 where apparently login with Github was broken by this line: decaporg#7172 (comment) See also: decaporg#5844 (comment)
