A few more tips on getting started in a safe way, and avoiding surprises:
* Use "hg outgoing" to see beforehand what "hg push" would do; the same
works for "hg incoming" and "hg pull".
There is a real danger of messing up our central push area by merging
it with my earlier attempt of the CVS -> hg conversion, which I had to
discontinue some months ago. If you still happen to have a clone
around on your machine, delete it now!
* An easy way to protect against gross mistakes is to install the
following hook in your ~/.hgrc on the home directory at TUM:
[hooks]
pretxnchangegroup = /home/isabelle-repository/repos/sanity-check
The sanity check prevents pushes that are unusually big, or consist of
a large number of changesets -- as in the above case of merging with
the bogus version of the old Isabelle repository.
This hook is installed in /home/isabelle-repository/repos/.hg/hgrc
already, but the Mercurial security model prevents its execution if
you are not wenzelm. This is what the warning "Not trusting file ..."
refers to.
