+Evolve: Concepts
+----------------
+
+Getting the most out of software requires an accurate understanding of
+the concepts underlying it. For example, you cannot use Mercurial to
+its full potential without understanding the DAG (directed acyclic
+graph) of changesets and the meaning of parent/child relationships
+between nodes in that graph. Mercurial with changeset evolution adds
+some additional concepts to the graph of changesets. Understanding
+those concepts will make you an informed and empowered user of
+``evolve``.
+
+.. note:: This document contains math! If you have a pathological fear
+ of set theory and the associated notation, you might be
+ better off just reading the `user guide`_. But if you
+ appreciate the theoretical rigour underlying core Mercurial,
+ you will be happy to know that it continues right into
+ changeset evolution.
+
+.. note:: This document is incomplete! (The formatting of the math
+ isn't quite right yet, and the diagrams are missing for
+ malformatted.)
+
+This document follows standard set theory notation:
+
+ x ∈ A: x is a member of A
+
+ A ∪ B: union of A and B: { x | x ∈ A or x ∈ B }
+
+ A ∖ B: set difference: { x | x ∈ A and x ∉ B }
+
+ A ⊇ B: superset: if x ∈ B, then x ∈ A
+
+.. _`user guide`: user-guide.html
+
+Phases
+------
+
+First, every changeset in a Mercurial repository (since 2.3) has a
+*phase*. Phases are independent of ``evolve`` and they affect
+Mercurial usage with or without changeset evolution. However, they
+were implemented in order to support evolution, and are a critical
+foundation of ``evolve``.
+
+Phases are strictly ordered:
+
+ secret > draft > public
+
+Changesets generally only move from a higher phase to a lower phase.
+Typically, changesets start life in *draft* phase, and move to
+*public* phase when they are pushed to a public repository. (You can
+set the default phase of new commits in Mercurial configuration.)
+
+The purpose of phases is to prevent modifying published history.
+``evolve`` will therefore only let you rewrite changesets in one of
+the two *mutable* phases (secret or draft).
+
+Run ``hg help phases`` for more information on phases.
+
+Obsolete changesets
+-------------------
+
+*Obsolescence* is they key concept at the heart of changeset
+evolution. Everything else in this document depends on understanding
+obsolescence. So: what does it mean for a changeset to be obsolete?
+
+In implementation terms, there is an *obsolescence marker* associated
+with changesets: every changeset is either obsolete or not.
+
+The simplest way that a changeset becomes obsolete is by *pruning* it.
+The ``hg prune`` command simply marks the specified changesets
+obsolete, as long as they are mutable.
+
+More commonly, a changeset *A* becomes obsolete by *amending* it.
+Amendment creates a new changeset *A'* that replaces *A*, which is now
+obsolete. *A'* is the successor of *A*, and *A* the predecessor of *A'*:
+
+ [diagram: A and A' with pred/succ edge]
+
+The predecessor/successor relationship forms an additional
+*obsolescence graph* overlaid on top of the traditional DAG formed by
+changesets and their parent/child relationships. In fact, the
+obsolescence graph is second-order version control. Where the
+traditional parent/child DAG tracks changes to your source code, the
+obsolescence graph tracks changes to your changesets. It tracks the
+evolution of your changesets.
+
+(If you prefer a calculus metaphor to set theory, it might help to
+think of the traditional parent/child DAG as the first derivative of
+your source code, and the obsolescence DAG as the second derivative.)
+
+Troubled changesets (unstable, bumped, divergent)
+-------------------------------------------------
+
+Evolving history can introduce problems that need to be solved. For
+example, if you prune a changeset *P* but not its descendants, those
+descendants are now on thin ice. To push a changeset to another
+repository *R*, all of its ancestors must be present in *R* or pushed
+at the same time. But Mercurial does not push obsolete changesets like
+*P*, so it cannot push the descendants of *P*. Any non-obsolete
+changeset that is a descendant of an obsolete changeset is said to be
+*unstable*.
+
+ [diagram: obsolete cset with non-obsolete descendant]
+
+Another sort of trouble occurs when two developers, Alice and Bob,
+collaborate via a shared non-publishing repository. (This is how
+developers can safely `share mutable history`_.) Say Alice and Bob
+both start the day with changeset *C* in *draft* phase. If Alice
+pushes *C* to their public repository, then it is now published and
+therefore immutable. But Bob is working from a desert island and
+cannot pull this change in *C*'s phase. For Bob, *C* is still in draft
+phase and therefore mutable. So Bob amends *C*, which marks it
+obsolete and replaces it with *C'*. When he is back online and pulls
+from the public repository, Mercurial learns that *C* is public, which
+means it cannot be obsolete. We say that *C'* is *bumped*, since it is
+the successor of a public changeset.
+
+.. _`share mutable history`: sharing.html
+
+(Incidentally, the terminology here comes from airline overbooking: if
+two people have bought tickets for the same seat on a plane and they
+both show up at the airport, only one of them gets on the plane. The
+passenger who is left behind in the airport terminal has been
+"bumped".)
+
+The third sort of trouble is when Alice and Bob both amend the same
+changeset *C* to have different successors. When this happens, the
+successors are both called *divergent* (unless one of them is in
+public phase; only mutable changesets are divergent).
+
+The collective term for unstable, bumped, and divergent changeset is
+*troubled*:
+
+ troubled = unstable ∪ bumped ∪ divergent
+
+It is possible for a changeset to be in any of the troubled categories
+at the same time: it might be unstable and divergent, or bumped and
+divergent, or whatever.
+
+ [diagram: Venn diagram of troubled changesets, showing overlap]
+
+The presence of troubled changesets indicates the need to run ``hg
+evolve``.
+
+Hidden (and visible) changesets
+-------------------------------
+
+Some obsolete changesets are *hidden*: deliberately suppressed by
+Mercurial and usually not visible through the UI. (As of Mercurial
+2.9, there are still some commands that inadvertently reveal hidden
+changesets; these are bugs and will be fixed in due course.)
+
+All hidden changesets are obsolete, and all obsolete changesets are
+part of your repository. Mathematically speaking:
+
+ repo ⊇ obsolete ⊇ hidden
+
+Or, putting it visually:
+
+ [diagram: Venn diagram showing nested strict subsets]
+
+However, the presence of obsolete but not hidden changesets should be
+temporary. The desired end state for any history mutation operation is
+that all obsolete changesets are hidden, i.e.:
+
+ repo ⊇ obsolete, obsolete = hidden
+
+Visually:
+
+ [diagram: Venn diagram showing obsolete = hidden, subset of repo]
+
+
+Why is this changeset visible?
+------------------------------
+
+Any changeset which is not hidden is *visible*. That is,
+
+ visible = repo ∖ hidden
+
+(Recall that ∖ means set difference: *visible* is the set of
+changesets that are in *repo* but not in *hidden*.)
+
+After amending or pruning a changeset, you might expect it to be
+hidden. It doesn't always work out that way. The precise rules are:
+
+ hideable = obsolete
+ blockers = bookmarks ∪ parents(workingcopy) ∪ localtags
+ hidden = hideable ∖ ancestors((repo ∖ hideable) ∪ blockers)
+
+This will probably be clearer with a worked example. First, here's a
+repository with some obsolete changesets, some troubled changesets,
+one bookmark, a working copy, and some hidden changesets:
+
+ x-x
+ /
+ -o-o-o-o
+ \
+ x-x-o
+
+Here's the computation required to determine which changesets are
+hidden:
+
+ repo = { 0, 1, 2, 3, 4, 5, 6, 7, 8 }
+
+ hideable = obsolete = { 2, 4, 5, 8 }
+
+ blockers = { 6 } ∪ { 4 } ∪ {}
+
+ blockers = { 4, 6 }
+
+ hidden = hideable ∖ ancestors((repo ∖ { 2, 4, 5, 8 }) ∪ { 4, 6 })
+
+ hidden = hideable ∖ ancestors({ 0, 1, 3, 6, 7 } ∪ { 4, 6 })
+
+ hidden = hideable ∖ ancestors({ 0, 1, 3, 4, 6, 7 })
+
+ hidden = { 2, 4, 5, 8 } ∖ { 0, 1, 2, 3, 4, 5, 6, 7 }
+
+ hidden = { 8 }

-Changeset Evolution Experimentation
-========================================

-This is the online documentation of the `evolve extension`_. An experimental
-extension that drive the implementation of the `changeset evolution concept`_ for
-Mercurial.
+==================================
+Changeset Evolution with Mercurial
+==================================
-.. _`evolve extension`: http://mercurial.selenic.com/wiki/EvolveExtension
-.. _`changeset evolution concept`: http://mercurial.selenic.com/wiki/ChangesetEvolution
+`evolve`_ is an experimental Mercurial extension for safe mutable history.
-Here are various materials on planned improvement to Mercurial regarding
-rewriting history.
+.. _`evolve`: http://mercurial.selenic.com/wiki/EvolveExtension
-First, read about what challenges arise while rewriting history and how we plan to
-solve them once and for all.
-
-.. toctree::
- :maxdepth: 2
-
- instability
-
-The effort is split in two parts:
+With core Mercurial, changesets are permanent and immutable. You can
+commit new changesets to modify your source code, but you cannot
+modify or remove old changesets—they are carved in stone for all
+eternity.
- * The **obsolescence marker** concept aims to provide an alternative to ``strip``
- to get rid of changesets. This concept has been partially implemented since
- Mercurial 2.3.
+For years, Mercurial has included various extensions that allow
+history modification: ``rebase``, ``mq``, ``histedit``, and so forth.
+These are useful and popular extensions, and in fact history
+modification is one of the big reasons DVCSes (distributed version
+control systems) like Mercurial took off.
- * The **evolve** Mercurial extension rewrites history using obsolete
- *marker* under the hood.
-
-The first and most important step is by far the **obsolescence marker**. However
-most users will never be directly exposed to the concept. For this reason
-this manual starts with changeset evolution.
+But there's a catch: until now, Mercurial's various mechanisms for
+modifying history have been *unsafe*, in that changesets were
+destroyed (“stripped”) rather than simply made invisible.
-Evolve: A robust alternative to MQ
-====================================
-
-Evolve is an experimental history rewriting extension that uses obsolete
-markers. It is inspired by MQ and pbranch but has multiple advantages over
-them:
-
-* Focus on your current work.
+``evolve`` makes things better in a couple of ways:
- You can focus your work on a single changeset and take care of adapting
- descendent changesets later.
-
-* Handle **non-linear history with branches and merges**
+ * It changes the behaviour of most existing history modification
+ extensions (``rebase``, ``histedit``, etc.) so they use a safer
+ mechanism (*changeset obsolescence*, covered below) rather than
+ the older, less safe *strip* operation.
-* Rely internally on Mercurial's **robust merge** mechanism.
+ * It provides a new way of modifying history that is roughly
+ equivalent to ``mq`` (but much nicer and safer).
- Simple conflicts are handled by real merge tools using the appropriate ancestor.
- Conflicts are much rarer and much more user friendly.
+It helps to understand that ``evolve`` builds on infrastructure
+already in core Mercurial:
-* Mutable history **fully available all the time**.
-
- Always use 'hg update' and forget about (un)applying patches to access the
- mutable part of your history.
-
-
-* Use only **plain changesets** and forget about patches. Evolve will create and
- exchange real changesets. Mutable history can be used in all usual operations:
- pull, push, log, diff, etc.
+ * *Phases* (starting in Mercurial 2.1) allow you to distinguish
+ mutable and immutable changesets. We'll cover phases early in the
+ user guide, since understanding phases is essential to
+ understanding ``evolve``.
-* Allow **sharing and collaboration** mutable history without fear of duplicates
- (thanks to obsolete marker).
-
-* Cover all MQ usage but guard.
-
-.. warning:: The evolve extension and obsolete markers are at an experimental
- stage. While using obsolete you willl likely be exposed to complex
- implications of the **obsolete marker** concept. I do not recommend
- non-power users to test this at this stage.
+ * *Changeset obsolescence* (starting in Mercurial 2.3) is how
+ Mercurial knows how history has been modified, specifically when
+ one changeset replaces another. In the obsolescence model, a
+ changeset is neither removed nor modified, but is instead marked
+ *obsolete* and typically replaced by a *successor*. Obsolete
+ changesets usually become *hidden* as well. Obsolescence is an
+ invisible feature until you start using ``evolve``, so we'll cover
+ it in the user guide too.
- While numbered 1.0.0, the command line API of this version should
- **not** be regarded as *stable*: command behavior, name and

-This concept is simple to define and provides a very solid base for:
-
-- very fast history rewriting operations
-

-
-- clean final history
-
-- share and collaborate on mutable parts of the history
+ * Share mutable history for code review: you don't want to publish

+ for code review. The solution is to share mutable history with
+ your reviewer, amending each changeset until it passes review.

+------------------------------
+Evolve: Shared Mutable History
+------------------------------
+
+Once you have mastered the art of mutable history in a single
+repository, you might want to move up to the next level: *shared*
+mutable history. ``evolve`` lets you push and pull draft changesets
+between repositories along with their obsolescence markers. This opens
+up a number of interesting possibilities.
+
+The most common scenario is a single developer working across two
+computers. Say you're working on code that must be tested on a remote
+test server, probably in a rack somewhere, only accessible by SSH, and
+running an “enterprise-grade” (out-of-date) OS. But you probably
+prefer to write code locally: everything is setup the way you like it,
+and you can use your preferred editor, IDE, merge/diff tools, etc.
+
+Traditionally, your options are limited: either
+
+ * (ab)use your source control system by committing half-working code
+ in order to get it onto the remote test server, or
+ * go behind source control's back by using ``rsync`` (or similar) to
+ transfer your code back-and-forth until it is ready to commit
+
+The former is less bad with distributed version control systems like
+Mercurial, but it's still far from ideal. (One important version
+control “best practice” is that every commit should make things just a
+little bit better, i.e. you should never commit code that is worse
+than what came before.) The latter, avoiding version control entirely,
+means that you're walking a tightrope without a safety net. One
+accidental ``rsync`` in the wrong direction could destroy hours of
+work.
+
+Using Mercurial with ``evolve`` to share mutable history solves all of
+these problems. As with single-repository ``evolve``, you can commit
+whenever the code is demonstrably better, even if all the tests aren't
+passing yet—just ``hg amend`` when they are. And you can transfer
+those half-baked changesets between repositories to try things out on
+your test server before anything is carved in stone.
+
+A less common scenario is multiple developers sharing mutable history.
+(This is in fact how Mercurial itself is developed.) We'll cover this
+scenario later. But first, single-user sharing.
+
+Publishing and non-publishing repositories
+------------------------------------------
+
+The key to shared mutable history is to keep your changesets in
+*draft* phase as you pass them around. Recall that by default, ``hg
+push`` promotes changesets from *draft* to *public*, and public
+changesets are immutable. You can change this behaviour by
+reconfiguring the *target* repository so that it is non-publishing.
+(Short version: set ``phases.publish`` to ``false``. Long version
+follows.)
+
+Setting things up
+-----------------
+
+We'll work an example with three local repositories, although in the
+real world they'd most likely be on three different computers. First,
+the public repository is where tested, polished changesets live, and
+it is where you push/pull changesets to/from the rest of your team. ::
+
+ $ hg init public
+
+We'll need two clones where work gets done::
+
+ $ hg clone -q public test-repo
+ $ hg clone -q test-repo dev-repo
+
+``dev-repo`` is your local machine, with GUI merge tools and IDEs and
+everything configured just the way you like it. ``test-repo`` is the
+test server in a rack somewhere behind SSH. So for the most part,
+we'll develop in ``dev-repo``, push to ``test-repo``, test and polish
+there, and push to ``public``.
+
+The key to making this whole thing work is to make ``test-repo``
+non-publishing::
+
+ $ cat >> test-repo/.hg/hgrc <<EOF
+ [phases]
+ publish = false
+ EOF
+
+We also have to configure ``evolve`` in both ``test-repo`` and
+``dev-repo``, so that we can amend and evolve in both of them. ::
+
+ $ cat >> test-repo/.hg/hgrc <<EOF
+ [extensions]
+ rebase =
+ evolve = /path/to/mutable-history/hgext/evolve.py
+ EOF
+ $ cat >> dev-repo/.hg/hgrc <<EOF
+ [extensions]
+ rebase =
+ evolve = /path/to/mutable-history/hgext/evolve.py
+ EOF
+
+Keep in mind that in real life, these repositories would probably be
+on separate computers, so you'd have to login to each one to configure
+each repository.
+
+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 -u
+
+Amending a shared changeset
+---------------------------
+
+Everything you learned in the `user guide`_ applies to work done in
+``dev-repo``. You can commit, amend, uncommit, evolve, and so forth
+just as before.
+
+.. _`user guide`: user-guide.html
+
+Things get different when you push changesets to ``test-repo``. Or
+rather, things stay the same, which *is* different: because we
+configured ``test-repo`` to be non-publishing, draft changesets stay
+draft when we push them to ``test-repo``. Importantly, they're also
+draft (mutable) in ``test-repo``.
+
+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 ../test-repo
+
+At this point, ``dev-repo`` and ``test-repo`` have the same changesets
+in the same phases:
+
+ [figure SG01: rev 0:0dc9 public, rev 1:f649 draft, same on both repos]
+
+(You may notice a change in notation from the user guide: now
+changesets are labelled with their revision number and the first four
+digits of the 40-digit hexadecimal changeset ID. Mercurial revision
+numbers are never stable when working across repositories, especially
+when obsolescence is involved. We'll see why shortly.)
+
+Now let's switch to ``test-repo`` to test our change::
+
+ $ cd ../test-repo
+ $ hg update
+
+Don't forget to ``hg update``! Pushing only adds changesets to a
+remote repository; it does not update the working directory (unless
+you have a hook that updates for you).
+
+Now let's imagine the tests failed because we didn't use proper
+punctuation and capitalization (oops). Let's amend our preliminary fix
+(and fix the lame commit message while we're at it)::
+
+ $ echo 'Fix fix fix.' > file1
+ $ hg amend -m 'fix bug 37'
+
+Now we're in a funny intermediate state (figure 2): revision 1:f649 is
+obsolete in ``test-repo``, having been replaced by revision 3:60ff
+(revision 2:2a03 is another one of those temporary amend commits that
+we saw in the user guide)—but ``dev-repo`` knows nothing of these
+recent developments.
+
+ [figure SG02: rev 0:0dc9 public, rev 1:f649, 2:2a03 obsolete, rev 3:60ff draft -- but dev-repo same as in SG01]
+
+Let's resynchronize::
+
+ $ cd ../dev-repo
+ $ hg pull -u
+
+As seen in figure 3, this transfers the new changeset *and* the
+obsolescence marker for revision 1. However, it does *not* transfer
+the temporary amend commit, because it is obsolete. Push and pull
+transfer obsolesence markers between repositories, but they do not
+normally transfer obsolete changesets.
+
+ [figure SG03: dev-repo grows new rev 2:60ff, marks 1:f649 obsolete]
+
+Because of this deliberately incomplete synchronization, revision
+numbers in ``test-repo`` and ``dev-repo`` are no longer consistent. We
+*must* use changeset IDs.
+
+Amend again, locally
+--------------------
+
+This process can repeat. Perhaps you figure out a more elegant fix to
+the bug, and want to mutate history so nobody ever knows you had a
+less-than-perfect idea. We'll implement it locally in ``dev-repo`` and
+push to ``test-repo``::
+
+ $ echo 'Fix, fix, and fix.' > file1
+ $ hg amend
+ $ hg push
+
+This time around, the temporary amend commit is in ``dev-repo``, and
+it is not transferred to ``test-repo``—the same as before, just in the
+opposite direction. Figure 4 shows the two repositories after amending
+in ``dev-repo`` and pushing to ``test-repo``.
+
+ [figure SG04: each repo has one temporary amend commit, but they're different in each one]
+
+Let's hop over to ``test-repo`` to test the more elegant fix::
+
+ $ cd ../test-repo
+ $ hg update -q
+
+This time, all the tests pass, so no further amendment is required.
+This bug fix is finished, so we push it to the public repository::
+
+ $ hg push
+ [...]
+ added 1 changesets with 1 changes to 1 files
+
+Note that only one changeset—the final version, after two
+amendments—was actually pushed. Again, Mercurial normally doesn't
+transfer obsolete changesets on push and pull. (Specifically, it
+doesn't transfer *hidden* changesets: roughly speaking, obsolete
+changesets with no non-obsolete descendants. If you're curious, see
+the `concept guide`_ for the precise definition of hidden.)
+
+.. _`concept guide`: concepts.html
+
+So the picture in ``public`` is much simpler than in either
+``dev-repo`` or ``test-repo``. None of our missteps or amendments are
+visible publicly, just the final, beautifully polished changeset:
+
+ [figure SG05: public repo with rev 0:0dc9, 1:de61, both public]
+
+There is one important step left to do. Because we pushed from
+``test-repo`` to ``public``, the pushed changeset is in *public* phase
+in those two repositories. But ``dev-repo`` knows nothing of this:
+that changeset is still *draft* there. If we're not careful, we might
+mutate history in ``dev-repo``, obsoleting a changeset that is already
+public. Let's avoid that situation for now by pulling from
+``test-repo`` down to ``dev-repo``::
+
+ $ cd ../dev-repo
+ $ hg pull -u
+
+Getting into trouble
+--------------------
+
+Mercurial with ``evolve`` is a powerful tool, and using powerful tools
+can have consequences. (You can cut yourself badly with a sharp knife,
+but every competent chef keeps several around. Ever try to chop onions
+with a spoon?)
+
+In the user guide, we saw examples of *unstable* changesets, which are
+the most common type of troubled changeset. (Recall that a
+non-obsolete changeset with obsolete ancestors is unstable.)
+
+Two other types of trouble can crop up: *bumped* and *divergent*
+changesets. Both are more likely with shared mutable history,
+especially mutable history shared by multiple developers.
+
+To demonstrate, let's start with the ``public`` repository as we left
+it in the last example, with two immutable changesets (figure 5
+above). Two developers, Alice and Bob, start working from this point::
+
+ $ hg clone -q public alice
+ $ hg clone -q public bob
+
+We need to configure Alice's and Bob's working repositories similar to
+``test-repo``, i.e. make them non-publishing and enable ``evolve``::
+
+ $ cat >> alice/.hg/hgrc <<EOF
+ [phases]
+ publish = false
+ [extensions]
+ rebase =
+ evolve = /path/to/mutable-history/hgext/evolve.py
+ EOF
+ $ cp alice/.hg/hgrc bob/.hg/hgrc
+
+Bumped changesets: only one gets on the plane
+---------------------------------------------
+
+If two people show up at the airport with tickets for the same seat on
+the same plane, only one of them gets on the plane. The would-be
+traveller left behind in the airport terminal is said to have been
+*bumped*.
+
+Similarly, if Alice and Bob are collaborating on some mutable
+changesets, it's possible to get into a situation where an otherwise
+worthwhile changeset cannot be pushed to the public repository; it is
+bumped by an alternative changeset that happened to get there first.
+Let's demonstrate one way this could happen.
+
+It starts with Alice committing a bug fix. Right now, we don't yet
+know if this bug fix is good enough to push to the public repository,
+but it's good enough for Alice to commit. ::
+
+ $ cd alice
+ $ echo 'fix' > file2
+ $ hg commit -q -A -m 'fix bug 15'
+
+Now Bob has a bad idea: he decides to pull whatever Alice is working
+on and tweak her bug fix to his taste::
+
+ $ cd ../bob
+ $ hg pull -q -u ../alice
+ $ echo 'Fix.' > file2
+ $ hg amend -q -A -m 'fix bug 15 (amended)'
+
+(Note the lack of communication between Alice and Bob. Failing to
+communicate with your colleagues is a good way to get into trouble.
+Nevertheless, ``evolve`` can usually sort things out, as we will see.)
+
+ [figure SG06: Bob's repo with one amendment]
+
+After some testing, Alice realizes her bug fix is just fine as it is:
+no need for further polishing and amending, this changeset is ready to
+publish. ::
+
+ $ cd ../alice
+ $ hg push -q
+
+This introduces a contradiction: in Bob's repository, changeset 2:e011
+(his copy of Alice's fix) is obsolete, since Bob amended it. But in
+Alice's repository (and ``public``), that changeset is public: it is
+immutable, carved in stone for all eternity. No changeset can be both
+obsolete and public, so Bob is in for a surprise the next time he
+pulls from ``public``::
+
+ $ cd ../bob
+ $ hg pull -q -u
+ 1 new bumped changesets
+
+Figure 7 shows what just happened to Bob's repository: changeset
+2:e011 is now public, so it can't be obsolete. When that changeset was
+obsolete, it made perfect sense for it to have a successor, namely
+Bob's amendment of Alice's fix (changeset 4:fe88). But it's illogical
+for a public changeset to have a successor, so 4:fe88 is in trouble:
+it has been *bumped*.
+
+ [figure SG07: 2:e011 now public not obsolete, 4:fe88 now bumped]
+
+As usual when there's trouble in your repository, the solution is to
+evolve it::
+
+ $ hg evolve --all
+
+Figure 8 illustrate's Bob's repository after evolving away the bumped
+changeset. Ignoring the obsolete changesets, Bob now has a nice,
+clean, simple history. His amendment of Alice's bug fix lives on, as
+changeset 5:227d—albeit with a software-generated commit message. (Bob
+should probably amend that changeset to improve the commit message.)
+But the important thing is that his repository no longer has any
+troubled changesets, thanks to ``evolve``.
+
+ [figure SG08: 5:227d is new, formerly bumped changeset 4:fe88 now hidden]
+
+Divergent changesets
+--------------------
+
+In addition to *unstable* and *bumped*, there is a third kind of
+troubled changeset: *divergent*. When an obsolete changeset has two
+successors, those successors are divergent.
+
+To illustrate, let's start Alice and Bob at the same
+point—specifically, the point where Alice's repository currently
+stands. Bob's repository is a bit of a mess, so we'll throw it away
+and start him off with a copy of Alice's repository::
+
+ $ cd ..
+ $ rm -rf bob
+ $ cp -rp alice bob
+
+Now we'll have Bob commit a bug fix that could still be improved::
+
+ $ cd bob
+ $ echo 'pretty good fix' >> file1
+ $ hg commit -u bob -m 'fix bug 24 (v1)'
+
+This time, Alice meddles with her colleague's work (still a bad
+idea)::
+
+ $ cd ../alice
+ $ hg pull -q -u ../bob
+ $ echo 'better (alice)' >> file1
+ $ hg amend -u alice -m 'fix bug 24 (v2 by alice)'
+
+Here's where things change from the "bumped" scenario above: this
+time, the original author (Bob) decides to amend his changeset too. ::
+
+ $ cd ../bob
+ $ echo 'better (bob)' >> file1
+ $ hg amend -u bob -m 'fix bug 24 (v2 by bob)'
+
+At this point, the divergence exists, but only in theory: Bob's
+original changeset, 3:fe81, is obsolete and has two successors. But
+those successors are in different repositories, so the trouble is not
+visible to anyone yet. It will be as soon as one of our players pulls
+from the other's repository. Let's make Bob the victim again::
+
+ $ hg pull -q -u ../alice
+ not updating: not a linear update
+ (merge or update --check to force update)
+ 2 new divergent changesets
+
+The “not a linear update” is our first hint that something is wrong,
+but of course “2 new divergent changesets” is the real problem. Figure
+9 shows both problems.
+
+ [figure SG09: bob's repo with 2 heads for the 2 divergent changesets, 5:fc16 and 6:694f; wc is at 5:fc16, hence update refused; both are successors of obsolete 3:fe81, hence divergence]
+
+Now we need to get out of trouble. Unfortunately, a `bug`_ in
+``evolve`` means that the usual answer (run ``hg evolve --all``) does
+not work. Bob has to figure out the solution on his own: in this case,
+merge. To avoid distractions, we'll set ``HGMERGE`` to make Mercurial
+resolve any conflicts in favour of Bob. ::
+
+ $ HGMERGE=internal:local hg merge
+ $ hg commit -m merge
+
+.. _`bug`: https://bitbucket.org/marmoute/mutable-history/issue/48/
+
+This is approximately what ``hg evolve`` would do in this
+circumstance, if not for that bug. One annoying difference is that
+Mercurial thinks the two divergent changesets are still divergent,
+which you can see with a simple revset query::
+
+ $ hg log -q -r 'divergent()'
+ 5:fc16901f4d7a
+ 6:694fd0f6b503
+
+(That annoyance should go away when the bug is fixed.)
+
+Conclusion
+----------
+
+Mutable history is a powerful tool. Like a sharp knife, an experienced
+user can do wonderful things with it, much more wonderful than with a
+dull knife (never mind a rusty spoon). At the same time, an
+inattentive or careless user can do harm to himself or others.
+Mercurial with ``evolve`` goes to great lengths to limit the harm you
+can do by trying to handle all possible types of “troubled”
+changesets. But having a first-aid kit nearby does not excuse you from
+being careful with sharp knives.
+
+Mutable history shared across multiple repositories by a single
+developer is a natural extension of this model. Once you are used to
+using a single sharp knife on its own, it's pretty straightforward to
+chop onions and mushrooms using the same knife, or to alternate
+between two chopping boards with different knives.
+
+Mutable history shared by multiple developers is a scary place to go.
+Imagine a professional kitchen full of expert chefs tossing their
+favourite knives back and forth, with the occasional axe or chainsaw
+thrown in to spice things up. If you're confident that you *and your
+colleagues* can do it without losing a limb, go for it. But be sure to
+practice a lot first before you rely on it!

+
+Life without ``evolve``
+-----------------------
+
+Before we dive into learning about ``evolve``, let's look into some
+features of core Mercurial that interact with ``evolve``. ``commit``
+affects ``evolve``, and ``evolve`` modifies how ``commit --amend``
+works.
+
+Example 1: Commit a new changeset
+=================================
+
+To create a new changeset, simply run ``hg commit`` as usual.
+``evolve`` does not change the behaviour of ``commit`` at all.
+
+However, it's important to understand that new changesets are in the
+*draft* phase by default: they are mutable. This means that they can
+be modified by Mercurial's existing history-editing commands
+(``rebase``, ``histedit``, etc.), and also by the ``evolve``
+extension. Specifically, ``evolve`` adds a number of commands that can
+be used to modify history: ``amend``, ``uncommit``, ``prune``,
+``fold``, and ``evolve``. Generally speaking, changesets remain in
+*draft* phase until they are pushed to another repository, at which
+point they enter *public* phase. ::
+
+ $ hg commit -m 'implement feature X'
+ $ hg phase -r .
+ 1: draft
+
+(Strictly speaking, changesets only become public when they are pushed
+to a *publishing* repository. But all repositories are publishing by
+default; you have to explicitly configure repositories to be
+*non-publishing*. Non-publishing repositories are an advanced topic
+which we'll see when we get to `sharing mutable history`_.)
+
+.. _`sharing mutable history`: sharing.html
+
+Example 2: Amend a changeset (traditional)
+==========================================
+
+Imagine you've just committed a new changeset, and then you discover a
+mistake. Maybe you forgot to run the tests and a failure slipped in.
+You want to modify history so that you push one perfect changeset,
+rather than one flawed changeset followed by an "oops" commit. (Or
+perhaps you made a typo in the commit message—this is really feature
+*Y*, not feature X. You can't fix that with a followup commit.)
+
+This is actually trivial with plain vanilla Mercurial since 2.2: fix
+your mistake and run ::
+
+ $ hg commit --amend -m 'implement feature Y'
+
+to create a new, amended changeset. The drawback of doing this with
+vanilla Mercurial is that your original, flawed, changeset is removed
+from the repository. This is *unsafe* history editing. It's probably
+not too serious if all you did was fix a syntax error, but still.
+
+.. figure:: figures/figure-ug01.svg
+
+ Figure 1: unsafe history modification with core Mercurial (not
+ using ``evolve``): the original revision 1 is destroyed.
+
+(Incidentally, Mercurial's traditional history modification mechanism
+isn't *really* unsafe: any changeset(s) removed from the repository
+are kept in a backup directory, so you can manually restore them later
+if you change your mind. But it's awkward and inconvenient compared to
+the features provided by ``evolve`` and changeset obsolescence.)
+
+Life with ``evolve`` (basic usage)
+----------------------------------
+
+Once you enable the ``evolve`` extension, a number of features are
+available to you. First, we're going to explore several examples of
+painless, trouble-free history modification.
+
+Example 3: Amend a changeset (with ``evolve``)
+==============================================
+
+Outwardly, amending a changeset with ``evolve`` can look exactly the
+same as it does with core Mercurial (example 2)::
+
+ $ hg commit --amend -m 'implement feature Y'
+
+Alternately, you can use the new ``amend`` command added by
+``evolve``::
+
+ $ hg amend -m 'implement feature Y'
+
+(``hg amend`` is nearly synonymous with ``hg commit --amend``. The
+difference is that ``hg amend`` reuses the existing commit message by
+default, whereas ``hg commit --amend`` runs your editor if you don't
+pass ``-m`` or ``-l``.)
+
+Under the hood, though, things are quite different. Mercurial has
+simply marked the old changeset *obsolete*, replacing it with a new
+one. We'll explore what this means in detail later, after working
+through a few more examples.
+
+Example 4: Prune an unwanted changeset
+======================================
+
+Sometimes you make a change, and then decide it was such a bad idea
+that you don't want anyone to know about it. Or maybe it was a
+debugging hack that you needed to keep around for a while, but do not
+intend to ever push publicly. ::
+
+ $ echo 'debug hack' >> file1.c
+ $ hg commit -m 'debug hack'
+
+In either case, ``hg prune`` is the answer. ``prune`` simply marks
+changesets obsolete without creating any new changesets to replace
+them::
+
+ $ hg prune .
+ 1 changesets pruned
+ 1 files updated, 0 files merged, 0 files removed, 0 files unresolved
+ working directory now at 934359450037
+
+Outwardly, it appears that your “debug hack” commit never happened;
+we're right back where we started::
+
+ $ hg parents --template '{rev}:{node|short} {desc|firstline}\n'
+ 3:934359450037 implement feature Y
+
+In reality, though, the “debug hack” is still there, obsolete and hidden.
+
+Example 5: Uncommit changes to certain files
+============================================
+
+Occasionally you commit more than you intended: perhaps you made
+unrelated changes to different files, and thus intend to commit
+different files separately. ::
+
+ $ echo 'relevant' >> file1.c
+ $ echo 'irrelevant' >> file2.c
+
+If you forget to specify filenames on the ``commit`` command line,
+Mercurial commits all those changes together::
+
+ $ hg commit -m 'fix bug 234' # oops: too many files
+
+Luckily, this mistake is easy to fix with ``uncommit``::
+
+ $ hg uncommit file2.c
+ $ hg status
+ M file2.c
+
+Let's verify that the replacement changeset looks right (i.e.,
+modifies only ``file1.c``)::
+
+ $ hg parents --template '{rev}:{node|short} {desc|firstline}\n{files}\n'
+ 6:c8defeecf7a4 fix bug 234
+ file1.c
+
+As before, the original flawed changeset is still there, but obsolete
+and hidden. It won't be exchanged with other repositories by ``push``,
+``pull``, or ``clone``.
+
+Example 6: Fold multiple changesets together into one
+=====================================================
+
+If you're making extensive changes to fragile source code, you might
+commit more frequently than normal so that you can fallback on a
+known good state if one step goes badly. ::
+
+ $ echo step1 >> file1.c
+ $ hg commit -m 'step 1' # revision 7
+ $ echo step2 >> file1.c
+ $ hg commit -m 'step 2' # revision 8
+ $ echo step3 >> file2.c
+ $ hg commit -m 'step 3' # revision 9
+
+At the end of such a sequence, you often end up with a series of small
+changesets that are tedious to review individually. It might make more
+sense to combine them into a single changeset using the ``fold``
+command.
+
+To make sure we pass the right revisions to ``fold``, let's review the
+changesets we just created, from revision 7::
+
+ $ hg log --template '{rev}:{node|short} {desc|firstline}\n' -r 7::
+ 7:05e61aab8294 step 1
+ 8:be6d5bc8e4cc step 2
+ 9:35f432d9f7c1 step 3
+
+and fold them::
+
+ $ hg fold -m 'fix bug 64' -r 7::
+ 3 changesets folded
+ 1 files updated, 0 files merged, 0 files removed, 0 files unresolved
+
+This time, Mercurial marks three changesets obsolete, replacing them
+all with a single *successor*.
+
+(You might be familiar with this operation under other names, like
+*squash* or *collapse*.)
+
+Changeset obsolescence under the hood
+-------------------------------------
+
+So far, everything has gone just fine. We haven't run into merge
+conflicts or other trouble. Before we start exploring advanced usage
+that can run into trouble, let's step back and see what happens when
+Mercurial marks changesets obsolete. That will make it much easier to
+understand the more advanced use cases we'll see later.
+
+When you have the ``evolve`` extension enabled, all history
+modification uses the same underlying mechanism: the original
+changesets are marked *obsolete* and replaced by zero or more
+*successors*. The obsolete changesets are the *precursors* of their
+successors. This applies equally to built-in commands (``commit
+--amend``), commands added by ``evolve`` (``amend``, ``prune``,
+``uncommit``, ``fold``), and even commands provided by other
+extensions (``rebase``, ``histedit``).
+
+Another way of looking at it is that obsolescence is second-order
+version control, i.e. the history of your history. We'll cover this in
+more detail (and mathematical precision) in the `concepts`_ guide.
+
+.. _`concepts`: concepts.html
+
+Under the hood: Amend a changeset
+=================================
+
+Consider Example 2, amending a changeset with ``evolve``. We saw above
+that you can do this using the exact same command-line syntax as core
+Mercurial, namely ``hg commit --amend``. But the implementation is
+quite different, and Figure 2 shows how.
+
+.. figure:: figures/figure-ug02.svg
+
+ Figure 2: safe history modification using ``evolve``: the original
+ revision 1 is preserved as an obsolete changeset. (The "temporary
+ amend commit", marked with T, is an implementation detail stemming
+ from limitations in Mercurial's current merge machinery. Future
+ versions of Mercurial will not create them.)
+
+In this case, the obsolete changesets are also *hidden*. That is the
+usual end state for obsolete changesets. But many scenarios result in
+obsolete changesets that are still visible, which indicates your
+history modification work is not yet done. We'll see examples of that
+later, when we cover advanced usage.
+
+Seeing hidden changesets
+========================
+
+TODO
+
+Under the hood: Prune an unwanted changeset
+===========================================
+
+``prune`` (example 4 above) is the simplest history modification
+command provided by ``evolve``. All it does is mark the specified
+changeset(s) obsolete, with no successor/precursor relationships
+involved. (If the working directory parent was one of the obsolete
+changesets, ``prune`` updates back to a suitable ancestor.)
+
+.. figure:: figures/figure-ug03.svg
+
+ Figure 3: pruning a changeset marks it obsolete with no successors.
+
+Under the hood: Uncommit changes to certain files
+=================================================
+
+In one sense, ``uncommit`` is a simplified version of ``amend``. Like
+``amend``, it obsoletes one changeset and leaves it with a single
+successor. Unlike ``amend``, there is no ugly "temporary amend commit"
+cluttering up the repository.
+
+In another sense, ``uncommit`` is the inverse of ``amend``: ``amend``
+takes any uncommitted changes in the working dir and “adds”
+them to the working directory's parent changeset. (In reality, of
+course, it creates a successor changeset, marking the original
+obsolete.) In contrast, ``uncommit`` takes some changes in the working
+directory's parent and moves them to the working dir, creating a new
+successor changeset in the process. Figure 4 illustrates.
+
+.. figure:: figures/figure-ug04.svg
+
+ Figure 4: uncommit moves some of the changes from the working
+ directory parent into the working dir, preserving the remaining
+ changes as a new successor changeset. (N.B. revision 4 is not shown
+ here because it was marked obsolete in the previous example.)
+
+
+Under the hood: Fold multiple changesets together into one
+==========================================================
+
+The last basic example is folding multiple changesets into one, which
+marks multiple changesets obsolete, replacing them all with a single
+successor.
+
+.. figure:: figures/figure-ug05.svg
+
+ Figure 5: fold combines multiple changesets into a single
+ successor, marking the original (folded) changesets obsolete.
+
+
+Obsolete is not hidden
+======================
+
+TODO
+
+
+Understanding revision numbers
+==============================
+
+If you're trying these examples on your own, especially using ``hg
+log`` without ``--hidden``, you have probably noticed some funny
+business going on with revision numbers: there are now gaps in the
+sequence. That's something you don't see with plain vanilla Mercurial;
+normally, revision N is always followed by revision N+1.
+
+This is just the visible manifestation of hidden changesets. If
+revision 95 is followed by revision 98, that means there are two
+hidden changesets, 96 and 97, in between.
+
+Note that changeset IDs are still the permanent, immutable identifier
+for changesets. Revision numbers are, as ever, a handy shorthand that
+work in your local repository, but cannot be used across repositories.
+They also have the useful property of showing when there are hidden
+changesets lurking under the covers, which is why this document uses
+revision numbers.
+
+
+Life with ``evolve`` (advanced usage)
+-------------------------------------
+
+Now that you've got a solid understanding of how ``evolve`` works in
+concert with changeset obsolescence, let's explore some more advanced
+scenarios. All of these scenarios will involve *unstable* changesets,
+which is an unavoidable consequence of obsolescence. What really sets
+``evolve`` apart from other history modification mechanisms is the
+fact that it recognizes troubles like unstable changesets and provides
+a consistent way for you to get out of trouble.
+
+(Incidentally, there are two other types of trouble that changesets
+can get into with ``evolve``: they may be *divergent* or *bumped*.
+Both of those states are more likely to occur when `sharing mutable
+history`_, so we won't see them in this user guide.)
+
+.. _`sharing mutable history`: sharing.html
+
+
+Example 7: Amend an older changeset
+===================================
+
+Sometimes you don't notice your mistakes until after you have
+committed some new changesets on top of them. ::
+
+ $ hg commit -m 'fix bug 17' # rev 11 (mistake here)
+ $ hg commit -m 'cleanup' # rev 12
+ $ hg commit -m 'feature 23' # rev 13
+
+Traditionally, your only option is to commit an "oops" changeset that
+fixes your mistake. That works, of course, but it makes you look bad:
+you made a mistake, and the record of that mistake is recorded in
+history for all eternity. (If the mistake was in the commit message,
+too bad.)
+
+More subtly, there now exist changesets that are *worse* than what
+came before—the code no longer builds, the tests don't pass, or
+similar. Anyone reviewing these patches will waste time noticing the
+error in the earlier patch, and then the correction later on.
+
+You can avoid all this by amending the bad changeset and *evolving*
+subsequent history. Here's how it works, assuming you have just
+committed revision 13 and noticed the mistake in revision 11::
+
+ $ hg update 11
+ [...fix mistake...]
+ $ hg amend
+
+At this point, revision 11 is *obsolete* and revisions 12 and 13—the
+descendants of 11—are in a funny state: they are *unstable*.
+
+.. figure:: figures/figure-ug06.svg
+
+ Figure 6: amending a changeset with descendants means the amended
+ changeset is obsolete but remains visible; its non-obsolete
+ descendants are *unstable*. The temporary amend commit, revision
+ 14, is hidden because it has no non-obsolete descendants.
+
+All non-obsolete descendants of an obsolete changeset are unstable. An
+interesting consequence of this is that revision 11 is still visible,
+even though it is obsolete. Obsolete changesets with non-obsolete
+descendants are not hidden.
+
+The fix is to *evolve* history::
+
+ $ hg evolve --all
+
+This is a separate step, not automatically part of ``hg amend``,
+because there might be conflicts. If your amended changeset modifies a
+file that one of its descendants also modified, Mercurial has to fire
+up your merge tool to resolve the conflict. More importantly, you have
+to switch contexts from "writing code" to "resolving conflicts". That
+can be an expensive context switch, so Mercurial lets you decide when
+to do it.
+
+The end state, after ``evolve`` finishes, is that the original
+revisions (11-13) are obsolete and hidden. Their successor revisions
+(15-17) replace them.
+
+.. figure:: figures/figure-ug07.svg
+
+ Figure 7: evolve your repository (``hg evolve --all``) to take care
+ of instability. Unstable changesets become obsolete, and are
+ replaced by successors just like the amended changeset was.
+
+Example 8: Prune an older changeset
+===================================
+
+Let's say you've just committed the following changesets::
+
+ $ hg commit -m 'useful work' # rev 18
+ $ hg commit -m 'debug hack' # rev 19
+ $ hg commit -m 'more work' # rev 20
+
+You want to drop revision 19, but keep 18 and 20. No problem::
+
+ $ hg prune 19
+ 1 changesets pruned
+ 1 new unstable changesets
+
+As above, this leaves your repository in a funny intermediate state:
+revision 20 is the non-obsolete descendant of obsolete revision 19.
+That is, revision 20 is unstable.
+
+.. figure:: figures/figure-ug08.svg
+
+ Figure 8: ``hg prune`` marks a changeset obsolete without creating
+ a successor. Just like with ``hg amend``, non-obsolete descendants
+ of the pruned changeset are now unstable.
+
+As before, the solution to unstable changesets is to evolve your
+repository::
+
+ $ hg evolve --all
+
+This rebases revision 20 on top of 18 as the new revision 21, leaving
+19 and 20 obsolete and hidden:
+
+.. figure:: figures/figure-ug09.svg
+
+ Figure 9: once again, ``hg evolve --all`` takes care of instability.
+
+Example 9: Uncommit files from an older changeset (discard changes)
+=======================================================================
+
+As in example 5, let's say you accidentally commit some unrelated
+changes together. Unlike example 5, you don't notice your mistake
+immediately, but commit a new changeset on top of the bad one. ::
+
+ $ echo 'this fixes bug 53' >> file1.c
+ $ echo 'debug hack' >> file2.c
+ $ hg commit -m 'fix bug 53' # rev 22 (oops)
+ $ echo 'and this handles bug 67' >> file1.c
+ $ hg commit -m 'fix bug 67' # rev 23 (fine)
+
+As with ``amend``, you need to travel back in time and repair revision
+22, leaving your changes to ``file2.c`` back in the working
+directory::
+
+ $ hg update 22
+ 1 files updated, 0 files merged, 0 files removed, 0 files unresolved
+ $ hg uncommit file2.c
+ 1 new unstable changesets
+ $ hg status
+ M file2.c
+
+Now your repository has unstable changesets, so you need to evolve it.
+But ``hg evolve`` requires a clean working directory to resolve merge
+conflicts, so you need to decide what to do with ``file2.c``.
+
+In this case, the change to ``file2.c`` was a temporary debugging
+hack, so we can discard it and immediately evolve the instability away::
+
+ $ hg revert file2.c
+ $ hg evolve --all
+ move:[23] fix bug 67
+ atop:[24] fix bug 53
+
+Figure 10 illustrates the whole process.
+
+.. figure:: figures/figure-ug10.svg
+
+ Figure 10: ``hg uncommit`` of a changeset with descendants results
+ in instability *and* a dirty working directory, both of which must
+ be dealt with.
+
+
+Example 10: Uncommit files to an older changeset (keep changes)
+===================================================================
+
+This is very similar to example 9. The difference that this time, our
+change to ``file2.c`` is valuable enough to commit, making things a
+bit more complicated. The setup is nearly identical::
+
+ $ echo 'fix a bug' >> file1.c
+ $ echo 'useful but unrelated' >> file2.c
+ $ hg commit -u dan -d '11 0' -m 'fix a bug' # rev 26 (oops)
+ $ echo 'new feature' >> file1.c
+ $ hg commit -u dan -d '12 0' -m 'new feature' # rev 27 (fine)
+
+As before, we update back to the flawed changeset (this time,
+revision 26) and ``uncommit``, leaving uncommitted changes to
+``file2.c`` in the working dir::
+
+ $ hg update -q 26
+ 1 files updated, 0 files merged, 0 files removed, 0 files unresolved
+ $ hg uncommit -q file2.c # obsoletes rev 26, creates rev 28
+ 1 new unstable changesets
+ $ hg status
+ M file2.c
+
+This time, let's save that useful change before evolving::
+
+ $ hg commit -m 'useful tweak' # rev 29
+
+Figure 11 shows the story so far: ``uncommit`` obsoleted revision 26
+and created revision 28, the successor of 26. Then we committed
+revision 29, a child of 28. We still have to deal with the unstable
+revision 27.
+
+.. figure:: figures/figure-ug11.svg
+
+ Figure 11: Uncommitting a file and then committing that change
+ separately will soon result in a two-headed repository.
+
+This is where things get tricky. As usual when a repository has
+unstable changesets, we want to evolve it::
+
+ $ hg evolve --all
+
+The problem is that ``hg evolve`` rebases revision 27 onto revision
+28, creating 30 (the successor of 27). This is entirely logical: 27
+was the child of 26, and 26's successor is 28. So of course 27's
+successor (30) should be the child of 26's successor (28).
+Unfortunately, that leaves us with a two-headed repository:
+
+.. figure:: figures/figure-ug12.svg
+
+ Figure 12: ``evolve`` takes care of unstable changesets; it does
+ not solve all the world's problems.
+
+As usual when faced with a two-headed repository, you can either merge
+or rebase. It's up to you.
+
