How can I create a mercurial hook that prevents new heads?

Question

I have several repositories that have been converted from SVN and moving forward we want make sure when people push to the repository they can\'t create additional heads. th

Answer 1

Use hg ci -m 'Closed branch feature-x' --close-branch to close all but one head and then apply a normal single-head hook.

Answer 2

By default, hg push prevents pushing of additional heads, requiring the -f flag. You could write a Mercurial extension to make it ignore that flag, effectively disabling pushing of new heads.

That said, I would question the wisdom of mechanically disallowing new heads. Instead, I would train your team to merge properly before pushing, while still allowing them to do it on the rare occasion that it makes sense, especially since Mercurial already warns you.
