Failed to import extension kiln.py

Question

Upgraded to Mercurial 4.7 and now I get "*** failed to import extension kiln from <....>: 'module' object has no attribute 'command'" I have to enter id/password manually. What is wrong?

Answer 1

You're using Kiln Extensions and there are some changes in Mercurial 4.7 that break this.

In regards to the error you referenced, the Mercurial release notes indicate (Section 7, API Changes):

cmdutil: drop deprecated precursor of registrar.command

So you can resolve this specific issue by replacing cmdutil.command with registrar.command but that'll just expose other problems.

Personally, I didn't have any more time to mess around with this so I just downgraded to Mercurial 4.6.1.
