This Mercurial configuration example is used for testing.

  added 1 changesets with 1 changes to 1 files

Later I add additional item to my list

  $ hg commit -m "adding condiment"
  $ cat >> shopping << EOF

Getting rid of branchy history
----------------------------------

While I was working on my list. Someone made a change remotely.

  $ cd ../remote
  $ hg up -q
  $ sed -i'' -e 's/Spam/Spam Spam Spam/' shopping
  $ hg ci -m 'SPAM'

I now have a new head. Note that this remote head is immutable.

  $ hg log -G
  o  9ca060c80d74 (public): SPAM
  |
  | @  9d0363b81950 (draft): adding fruit
  | |
  | o  4d5dc8187023 (draft): adding condiment
  |/
  o  7e82d3f3c2cb (public): Monthy Python Shopping list
  

#if docgraph-ext

#endif

Instead of merging my head with the new one. I'm going to rebase my work

  $ hg diff
  $ hg rebase --dest 9ca060c80d74 --source 4d5dc8187023
  rebasing 1:4d5dc8187023 "adding condiment"
  merging shopping
  rebasing 3:9d0363b81950 "adding fruit"
  merging shopping


My local work is now rebased on the remote one.

not fit well in my standard shopping list)

  $ hg prune . # "." is for working directory parent
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 41aff6a42b75

.. note:: We can't amend changeset 7e82d3f3c2cb or 9ca060c80d74 as they are immutable.

 I now want to push to remote all my changes except the bathroom one, which I'm
 not totally happy with yet. To be able to push "SPAM SPAM" I need a version of
 "SPAM SPAM" which is not a child of "bathroom stuff"

You can use the 'grab' alias for that.

.. note: grab is an alias for `hg rebase --dest . --rev <target>; hg up <there>`

  $ hg up 'p1(10b8aeaa8cc8)' # going on "bathroom stuff" parent
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

To make sure I do not push unready changeset by mistake I set the "bathroom
stuff" changeset in the secret phase.

  $ hg phase --force --secret 10b8aeaa8cc8

we can now push our change:

  $ hg push remote
  pushing to $TESTTMP/remote (glob)

  adding manifests
  adding file changes
  added 3 changesets with 3 changes to 1 files
  5 new obsolescence markers

for simplicity sake we get the bathroom change in line again

  $ hg pick 10b8aeaa8cc8
  picking 8:10b8aeaa8cc8 "bathroom stuff"
  merging shopping
  $ hg phase --draft .

Splitting change
------------------

This part is not written yet, but you can use either the `histedit` extension
of the `uncommit` command to splitting a change.

  $ hg help uncommit
  hg uncommit [OPTION]... [FILE]...
  
  move changes from parent revision to working directory

  $ cd ../remote
  $ hg -R ../local/ showconfig phases
  [1]

The localrepo does not have any specific configuration for `phases.publish`. It
is ``true`` by default.

  $ hg pull local
  pulling from $TESTTMP/local (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  1 new obsolescence markers
  new changesets 4710c0968793
  (run 'hg update' to get a working copy)
  $ hg log -G

We do not want to publish the "bathroom changeset". Let's rollback the last transaction.

.. Warning: Rollback is actually a dangerous kind of internal command that is deprecated and should not be exposed to user. Please forget you read about it until someone fix this tutorial.

  $ hg rollback

Rebasing unstable change after pull
----------------------------------------------

Remotely someone add a new changeset on top of the mutable "bathroom" on.

  $ hg up 4710c0968793 -q
  $ cat >> shopping << EOF
  > Giraffe
  > Rhino
  > Lion
  > Bear

  $ hg ci -m 'animals'

But at the same time, locally, this same "bathroom changeset" was updated.

  $ cd ../local
  $ hg up 4710c0968793 -q
  $ sed -i'' -e 's/... More bathroom stuff to come/Bath Robe/' shopping
  $ hg commit --amend

The older version 75954b8cd933 never ceased to exist in the local repo. It was
just hidden and excluded from pull and push.

.. note:: In hgview there is a nice dotted relation highlighting a44c85f957d3 as a new version of 75954b8cd933. this is not yet ported to ``hg log -G``.

There is now an **unstable** changeset in this history. Mercurial will refuse to
share it with the outside:

  $ hg push other
  pushing to $TESTTMP/other (glob)
  searching for changes
  abort: push includes orphan changeset: e4e4fa805d92!
  (use 'hg evolve' to get a stable history or --force to ignore warnings)
  [255]
 

To resolve this unstable state, you need to rebase bf1b0d202029 onto
a44c85f957d3. The `hg evolve` command will do this for you.

It has a --dry-run option to only suggest the next move.

  $ hg evolve --dry-run
  move:[13] animals
  atop:[12] bathroom stuff
  hg rebase -r e4e4fa805d92 -d 682004e81e71

Let's do it

  $ hg evolve
  move:[13] animals

  merging shopping

The old version of bathroom is hidden again.

  $ hg log -G

Now let's see where we are, and update to the successor.

  $ hg parents

  working directory parent is obsolete! (e4e4fa805d92)
  (use 'hg evolve' to update to its successor: 2a2b36e14660)

In the mean time I noticed you can't buy animals in a super market and I prune the animal changeset:

  working directory is now at 682004e81e71

The animals changeset is still displayed because the "SPAM SPAM SPAM" changeset
is neither dead or obsolete. My repository is in an unstable state again.

Instead of merging my head with the new one. I'm going to rebase my work

  $ hg diff
  $ hg rebase --dest 9ca060c80d74 --source 63ae8c44f4b6

I have a new commit but I realize that don't want it. (Transport shopping list
does not fit well in my standard shopping list)

.. note:: We can't amend changeset 7e82d3f3c2cb or 9ca060c80d74 as they are immutable.

I now want to push to remote all my changes except the bathroom one, which I'm
not totally happy with yet. To be able to push "SPAM SPAM" I need a version of
"SPAM SPAM" which is not a child of "bathroom stuff".

You can use the 'grab' command for that.

.. note:: `grab` is an alias for `hg rebase --dest . --rev <target>; hg up <result>`

  $ hg up 'p1(d1928babc208)' # going on "bathroom stuff" parent
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg pick 1c877d31b53f # moving "SPAM SPAM" to the working directory parent

To make sure I do not push unfinished changeset by mistake I move the "bathroom
stuff" changeset to the secret phase.

  $ hg phase --force --secret d1928babc208

we can now push our change:

  $ hg push remote
  pushing to $TESTTMP/remote (glob)

  adding manifests
  adding file changes
  added 3 changesets with 3 changes to 1 files
  5 new obsolescence markers

for simplicity's sake we get the bathroom change in line again

  $ hg pick d1928babc208
  picking 8:d1928babc208 "bathroom stuff"
  merging shopping
  $ hg phase --draft .

Splitting change
------------------

This part is not written yet, but you can use either the `histedit` extension
or the `uncommit` command to split a change.

  $ hg help uncommit
  hg uncommit [OPTION]... [FILE]...
  
  move changes from parent revision to working directory

  $ cd ../remote
  $ hg -R ../local/ showconfig phases
  [1]

The local repo does not have any specific configuration for `phases.publish`.
It is ``true`` by default.

  $ hg pull local
  pulling from $TESTTMP/local (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  1 new obsolescence markers
  new changesets 39b19dc3d1e4

  $ hg log -G

We do not want to publish the "bathroom changeset". Let's rollback the last transaction.

.. warning:: `rollback` is actually a dangerous kind of internal command that is deprecated and should not be exposed to user. Please forget you read about it until someone fix this tutorial.

  $ hg rollback

Rebasing unstable change after pull
----------------------------------------------

Remotely someone add a new changeset on top of the mutable "bathroom" on.

  $ hg up 39b19dc3d1e4 -q
  $ cat >> shopping << EOF
  > Giraffe
  > Rhino
  > Lion
  > Bear

  $ hg ci -m 'animals'

But at the same time, locally, this same "bathroom changeset" was updated.

  $ cd ../local
  $ hg up 39b19dc3d1e4 -q
  $ sed -i'' -e 's/... More bathroom stuff to come/Bath Robe/' shopping
  $ hg commit --amend
  $ hg log -G

The new changeset "animal" is based on an old changeset of "bathroom". You can
see both version showing up in the log.

      }
#endif

The older version 39b19dc3d1e4 never ceased to exist in the local repo. It was
just hidden and excluded from pull and push.

.. note:: In hgview there is a nice dotted relation highlighting 5486682f4225 as a new version of 39b19dc3d1e4. This is not yet ported to ``hg log -G``.

There is now an **unstable** changeset in this history. Mercurial will refuse to
share it with the outside:

  $ hg push other
  pushing to $TESTTMP/other (glob)
  searching for changes
  abort: push includes orphan changeset: 0609f95eccab!
  (use 'hg evolve' to get a stable history or --force to ignore warnings)
  [255]
 

To resolve this unstable state, you need to rebase 0609f95eccab onto
5486682f4225. The `hg evolve` command will do this for you.

It has a --dry-run option to only suggest the next move.

  $ hg evolve --dry-run
  move:[13] animals
  atop:[12] bathroom stuff
  hg rebase -r 0609f95eccab -d 5486682f4225

Let's do it

  $ hg evolve
  move:[13] animals

  merging shopping

The old version of bathroom is hidden again.

Now let's see where we are, and update to the successor.

  $ hg parents

  working directory parent is obsolete! (0609f95eccab)
  (use 'hg evolve' to update to its successor: 3266db1117c9)

In the mean time I noticed you can't buy animals in a super market and I prune the animal changeset:

  $ hg prune 3266db1117c9
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 5486682f4225
  1 changesets pruned
  1 new orphan changesets


The animals changeset is still displayed because the "SPAM SPAM SPAM" changeset
is neither dead or obsolete. My repository is in an unstable state again.
