To start things off, let's make one public, immutable changeset::

  $ cd test-repo

  $ echo 'my new project' > file1

  $ hg add file1

  $ hg commit -m'create new project'

  $ hg push -q

and pull that into the development repository::

  $ cd ../dev-repo

  $ hg pull -q -u

Let's commit a preliminary change and push it to ``test-repo`` for

testing. ::

  $ echo 'fix fix fix' > file1

  $ hg commit -m'prelim change'

  $ hg push -q ../test-repo

  $ hg shortlog -G

  @  1:f6490818a721  draft  prelim change

  |

  o  0:0dc9c9f6ab91  public  create new project

Now let's switch to test-repo to test our change and amend::

  $ cd ../test-repo

  $ hg update -q

  $ echo 'Fix fix fix.' > file1

  $ hg amend -m'fix bug 37'

Sharing by Alice and Bob to demonstrate bumped and divergent changesets.

First, setup repos for them.

  $ cd ..

  $ hg clone -q public alice

  $ hg clone -q public bob

  $ cat >> alice/.hg/hgrc <<EOF

  > [phases]

  > publish = false

  > EOF

  $ cp alice/.hg/hgrc bob/.hg/hgrc

Alice commits a bug fix.

  $ cd alice

  $ echo 'fix' > file2

  $ hg commit -q -A -u alice -m 'fix bug 15'

Bob pulls and amends Alice's fix.

  $ cd ../bob

  $ hg pull -q -u ../alice

  $ echo 'Fix.' > file2

  $ hg amend -q -A -u bob -m 'fix bug 15 (amended)'

But in the meantime, Alice decides the fix is just fine and publishes it.

  $ cd ../alice

  $ hg push -q

Which means that Bob now has an formerly obsolete changeset that is

also public (2:6e83). As soon as he pulls its phase change, he's got

trouble: the successors of that formerly obsolete changeset are

bumped.

Throw away Bob's messy repo and start over.

  $ cd ..

  $ rm -rf bob

  $ cp -rp alice bob

Bob commits a pretty good fix that both he and Alice will amend,

leading to divergence.

  $ cd bob

  $ echo 'pretty good fix' >> file1

  $ hg commit -u bob -m 'fix bug 24 (v1)'

Alice pulls Bob's fix and improves it.

  $ cd ../alice

  $ hg pull -q -u ../bob

  $ echo 'better (alice)' >> file1

  $ hg amend -u alice -m 'fix bug 24 (v2 by alice)'

Likewise, Bob amends his own fix. Now we have an obsolete changeset

with two successors, although the successors are in different repos.

  $ cd ../bob

  $ echo 'better (bob)' >> file1

  $ hg amend -u bob -m 'fix bug 24 (v2 by bob)'

Bob pulls from Alice's repo and discovers the trouble: divergent changesets!

  $ hg pull -q -u ../alice

  not updating: not a linear update

  (merge or update --check to force update)

  2 new divergent changesets

  $ hg shortlog -r 'divergent()'
