git user.email failing to auto-detect

[danielballan]

Has anyone else seen this error?

*** Please tell me who you are.
Run
  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: unable to auto-detect email address (got 'travis@testing-docker-d1d30905-1f6c-4664-aa3b-7945fba5627e.(none)')

Doctr was previously working seamlessly, and I'm not sure what has changed. I can see from the log that doctr manually sets the git user.name but not the user.email. Maybe it should.

[asmeurer]

This was intentional. There's no email for doctr to set, so I just left it as the default, which is derived from the machine name.

[danielballan]

That makes sense. It looks like the default was previous acceptable to git, but now it is not.

[asmeurer]

So did doctr actually fail in that build?

[danielballan]

The build passed but the new doctr step did not complete successfully; the new docs were not uploaded. This is how it ended:

*** Please tell me who you are.
Run
  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.

Aborting
Done. Your build exited with 0.

[danielballan]

As you'd expected, manually setting the user.email before running doctr deploy fixes the problem. My guess is that git has become smart enough to know that Travis's default email address, which ends in .(none), is not a valid email address.

[asmeurer]

Ah, so git isn't committing, leading to the other errors. So there are two issues here:

• doctr needs to set an email (apparently)
• doctr isn't giving nonzero exit status, even though it failed

[asmeurer]

My guess is that Travis updated git recently. I searched the recent git release notes and found this, which seems relevant.

[asmeurer]

OK, I can reproduce the issue, but for me, the build fails.

[asmeurer]

Ah, it's because you have doctr deploy in after_success, which does not affect the build result. We should update the docs about this.

[asmeurer]

I guess we can use drdoctr@users.noreply.github.com https://help.github.com/articles/keeping-your-email-address-private/#step-2-tell-git-to-use-your-private-email-address. Can't think of a better dummy email.

[danielballan]

That all looks right to me. Thanks for the thorough follow-up.
