It does not seem to be possible to have two bridges using a common token with the same target:

The following was performed within a clean environment:

1. Initial clone of one repository (I've edited out my token), everything works as expected:

Error: missing identity token

The same issue also happens when running git bug bridge auth afterwards: Repo from 1):

[eve@computer git-bug]$ git bug bridge auth 
51e8d3f github     token eve $TOKEN

Repo from 2):

[eve@computer go-term-text]$ git bug bridge auth
Error: identity doesn't exist

My guess is that this is related to the credentials stored in the global .gitconfig file. After both bridges have been configured, there is only a single auth block (ids shortended as I don't know whether they leak information):

[git-bug "auth.51e8d..."]
	kind = token
	userid = a66bcfdac7e2687ddb9310fc27bd011a5b8e334d
	target = github
	createtime = 1578397411
	value = $TOKEN

As you can see, it maps to the userid of the user created in 1). If I edit userid to the userid from step 2 (so 605b22282a8abb56095422679affa4bf7872a98e) I can query auth (git bug bridge auth) pull (git bug bridge pull githubX) in the repo from 2), but not anymore in the one from 1).

Generally, it would be nice to have a general bridge configuration that is usable from all my repositories and not bound to an individual (repository-local) identity. So I'd rather have a bridge "github" with token from my account that I can use with all my repositories on github. If multiaccount-usage is required, the user could then create an "github-account2" bridge...

Thank you for this software and reading thus far in this bug report :) I hope this information is more-or-less complete and sufficient, but feel free to ping me if you need more information/a tester.

Best regards, Simon

You are correct in your assessment. The concept of global token came quite late in the bridge design and while you can configure multiple bridges within the same repository, I failed to realize that the userID are not common across repository. I'm working on a fix to address this problem in the cred-metadata branch

Instead of storing the user ID, bridges will be able to tag credentials with arbitrary metadata that they can search for later from another repo. Typically, bridges would store the user login or email.

This should be working now on the master branch, care to test ?

Hey, thanks for the effort!

I've tested it with multiple github-repositories and it seems to work as expected. Only read access was tested (sorry, currently have no bugs to report), but I could successfully register with the same credentials and only have one set of credentials stored in ~/.config/git/config.

I've always registered with full set of information (git bug bridge configure --name=github --target=github --token=... --url=https://github.com/.../...). If the new method has some concept of adopting an already configured set of credentials and you want that tested as well, feel free to ping me.

Once more thank you for the patch :)

Thanks for testing !
