The short question is: if I hg rollback, how does Peter get my rolled back version if he cloned from me? What are the exact steps he or me has to do or type?
This is related to In Mercurial, when Peter "hg clone" me, and I commit and he pull and update, he gets my version, but not when I rollback?
The details:
After the following steps, Mary has 7 and Peter has 11. My repository is 7
What are the exact steps Peter or me has to do or type SO THAT PETER GETS 7 back?
F:\>hg init hgme
F:\>cd hgme
F:\hgme>echo the code is 7 > code.txt
F:\hgme>hg add code.txt
F:\hgme>hg commit -m "this is version 1"
F:\hgme>cd ..
F:\>hg clone hgme hgpeter
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved

What are the exact steps Peter or me has to do or type SO THAT PETER GETS 7 back? There should be some steps that Peter can do to get the "current state" of my repository since he cloned from me. I shouldn't need to knock on his front door to tell him, "hey, you need to rollback" or whatever.
If someone has already pulled your changes (which is the case you're describing), a rollback isn't appropriate.
From hg manual:
This command is not intended for use on public repositories. Once changes are visible for pull by other users, rolling a transaction back locally is ineffective (someone else may already have pulled the changes). Furthermore, a race is possible with readers of the repository; for example an in-progress pull from the repository may fail if a rollback is performed.
What you should do is hg backout the changeset, then tell Peter to pull.
If you insist on rolling back, you could tell Peter to reclone the repository, but I wouldn't recommend working this way.
