test: adapt to output change from eb586ed5d8ce

Core have a more verbose output on pull. We have to update tests with it.

CORE-TEST-OUTPUT-UPDATE: eb586ed5d8ce

Initial setup
-------------

This Mercurial configuration example is used for testing.

.. Various setup

  $ cat >> $HGRCPATH << EOF
  > [ui]
  > # This is change the default output of log for clear tutorial
  > logtemplate ="{node|short} ({phase}): {desc}\n"
  > [diff]
  > # use "git" diff format, clearer and smarter format
  > git = 1
  > [alias]
  > # "-d '0 0'" means that the new commit will be at January 1st 1970.
  > # This is used for stable hash during test
  > # (this tutorial is automatically tested.)
  > amend = amend -d '0 0'
  > EOF

  $ hg init local
  $ cat >> local/.hg/hgrc << EOF
  > [paths]
  > remote = ../remote
  > other = ../other
  > [ui]
  > user = Babar the King
  > EOF

  $ hg init remote
  $ cat >> remote/.hg/hgrc << EOF
  > [paths]
  > local = ../local
  > [ui]
  > user = Celestine the Queen
  > EOF

  $ hg init other
  $ cat >> other/.hg/hgrc << EOF
  > [ui]
  > user = Princess Flore
  > EOF


This tutorial uses the following configuration for Mercurial:

A compact log template with phase data:

  $ hg showconfig ui | grep log
  ui.logtemplate="{node|short} ({phase}): {desc}\n"

Improved git format diff:

  $ hg showconfig diff
  diff.git=1

And of course, we enable the experimental extensions for mutable history:

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > evolve = $TESTDIR/../hgext3rd/evolve/
  > # enabling rebase is also needed for now
  > rebase =
  > EOF

#if docgraph-ext
  $ . "$TESTDIR/testlib/docgraph_setup.sh" #rest-ignore
#endif

-----------------------
Single Developer Usage
-----------------------

This tutorial shows how to use evolution to rewrite history locally.


Fixing mistake with `hg amend`
--------------------------------

We are versioning a shopping list

  $ cd local
  $ cat  >> shopping << EOF
  > Spam
  > Whizzo butter
  > Albatross
  > Rat (rather a lot)
  > Jugged fish
  > Blancmange
  > Salmon mousse
  > EOF
  $ hg commit -A -m "Monthy Python Shopping list"
  adding shopping

Its first version is shared with the outside.

  $ hg push remote
  pushing to $TESTTMP/remote (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

Later I add additional item to my list

  $ cat >> shopping << EOF
  > Egg
  > Suggar
  > Vinegar
  > Oil
  > EOF
  $ hg commit -m "adding condiment"
  $ cat >> shopping << EOF
  > Bananos
  > Pear
  > Apple
  > EOF
  $ hg commit -m "adding fruit"

This history is very linear

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'
  $ cd ../local

I'll get this remote changeset when pulling

  $ hg pull remote
  pulling from $TESTTMP/remote (glob)
  searching for changes

  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  new changesets 9ca060c80d74
  (run 'hg heads' to see heads, 'hg merge' to merge)

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

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

  rebasing 1:4d5dc8187023 "adding condiment"
  merging shopping
  rebasing 3:9d0363b81950 "adding fruit"
  merging shopping


My local work is now rebased on the remote one.

Reordering changesets
------------------------


We create two changesets.


  $ cat >> shopping << EOF
  > Shampoo
  > Toothbrush
  > ... More bathroom stuff to come
  > Towel
  > Soap
  > EOF
  $ hg ci -m 'bathroom stuff' -q # XXX remove the -q

  $ sed -i'' -e 's/Spam/Spam Spam Spam/g' shopping
  $ hg ci -m 'SPAM SPAM'
  $ hg log -G

  o  dfd3a2d7691e (draft): adding condiment
  |
  o  9ca060c80d74 (public): SPAM
  |
  o  7e82d3f3c2cb (public): Monthy Python 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' 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
  $ hg grab fac207dec9f5 # moving "SPAM SPAM" to the working directory parent

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)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 3 changes to 1 files

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]... [NAME]
  
  move changes from parent revision to working directory
  
      Changes to selected files in the checked out revision appear again as
      uncommitted changed in the working directory. A new revision without the
      selected changes is created, becomes the checked out revision, and
      obsoletes the previous one.
  
      The --include option specifies patterns to uncommit. The --exclude option
      specifies patterns to keep in the commit.
  
      The --rev argument let you change the commit file to a content of another
      revision. It still does not change the content of your file in the working
      directory.
  
      Return 0 if changed files are uncommitted.
  
  options ([+] can be repeated):
  
   -a --all                 uncommit all changes when no arguments given
   -r --rev VALUE           revert commit content to REV instead
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
   -m --message TEXT        use text as commit message
   -l --logfile FILE        read commit message from file
   -d --date DATE           record the specified date as commit date
   -u --user USER           record the specified user as committer
   -D --current-date        record the current date as commit date
   -U --current-user        record the current user as committer
  
  (some details hidden, use --verbose to show complete help)


The edit command of histedit can be used to split changeset:


Collapsing change
------------------

The tutorial part is not written yet but can use `hg fold`:

  $ hg help fold
  hg fold [OPTION]... [-r] REV
  
  aliases: squash
  
  fold multiple revisions into a single one
  
      With --from, folds all the revisions linearly between the given revisions
      and the parent of the working directory.
  
      With --exact, folds only the specified revisions while ignoring the parent
      of the working directory. In this case, the given revisions must form a
      linear unbroken chain.
  
  options ([+] can be repeated):
  
   -r --rev VALUE [+] revision to fold
      --exact         only fold specified revisions
      --from          fold revisions linearly to working copy parent
   -m --message TEXT  use text as commit message
   -l --logfile FILE  read commit message from file
   -d --date DATE     record the specified date as commit date
   -u --user USER     record the specified user as committer
   -D --current-date  record the current date as commit date
   -U --current-user  record the current user as committer
  
  (some details hidden, use --verbose to show complete help)

Collaboration
-----------------------


Sharing mutable changesets
----------------------------

To share mutable changesets with others, just check that the repo you interact
with is "not publishing". Otherwise you will get the previously observe
behavior where exchanged changeset are automatically published.

  $ 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 75954b8cd933
  (run 'hg update' to get a working copy)
  $ hg log -G
  o  75954b8cd933 (public): bathroom stuff
  |
  o  a224f2a4fb9f (public): SPAM SPAM
  |
  o  41aff6a42b75 (public): adding fruit
  |
  o  dfd3a2d7691e (public): adding condiment
  |
  @  9ca060c80d74 (public): SPAM
  |
  o  7e82d3f3c2cb (public): Monthy Python Shopping list
  

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
  repository tip rolled back to revision 4 (undo pull)
  $ hg log -G
  o  a224f2a4fb9f (public): SPAM SPAM
  |
  o  41aff6a42b75 (public): adding fruit
  |
  o  dfd3a2d7691e (public): adding condiment
  |
  @  9ca060c80d74 (public): SPAM
  |
  o  7e82d3f3c2cb (public): Monthy Python Shopping list
  

Let's make the local repo "non publishing".

  $ echo '[phases]' >> ../local/.hg/hgrc
  $ echo 'publish=false' >> ../local/.hg/hgrc
  $ echo '[phases]' >> .hg/hgrc
  $ echo 'publish=false' >> .hg/hgrc
  $ hg showconfig phases
  phases.publish=false
  $ hg -R ../local/ showconfig phases
  phases.publish=false


I can now exchange mutable changeset between "remote" and "local" repository.

  $ 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 75954b8cd933
  (run 'hg update' to get a working copy)
  $ hg log -G
  o  75954b8cd933 (draft): bathroom stuff
  |
  o  a224f2a4fb9f (public): SPAM SPAM
  |
  o  41aff6a42b75 (public): adding fruit

  o  dfd3a2d7691e (public): adding condiment
  |
  @  9ca060c80d74 (public): SPAM
  |
  o  7e82d3f3c2cb (public): Monthy Python Shopping list
  

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

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

  $ hg up 75954b8cd933 -q
  $ cat >> shopping << EOF
  > Giraffe
  > Rhino
  > Lion
  > Bear
  > EOF
  $ hg ci -m 'animals'

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

  $ cd ../local
  $ hg up 75954b8cd933 -q
  $ sed -i'' -e 's/... More bathroom stuff to come/Bath Robe/' shopping
  $ hg commit --amend
  $ hg log -G

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: bf1b0d202029!
  (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 bf1b0d202029 -d a44c85f957d3

Let's do it

  $ hg evolve
  move:[13] animals
  atop:[12] bathroom stuff
  merging shopping
  working directory is now at ee942144f952

The old version of bathroom is hidden again.

We can push this evolution to remote.

  $ hg push remote
  pushing to $TESTTMP/remote (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 2 changesets with 2 changes to 1 files (+1 heads)
  2 new obsolescence markers
  obsoleted 2 changesets

Remote get a warning that current working directory is based on an obsolete
changeset.

  $ cd ../remote
  $ hg pull local # we up again to trigger the warning. it was displayed during the push
  pulling from $TESTTMP/local (glob)
  searching for changes
  no changes found
  working directory parent is obsolete! (bf1b0d202029)
  (use 'hg evolve' to update to its successor: ee942144f952)

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

  $ hg parents

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

  $ hg prune ee942144f952
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory now at a44c85f957d3
  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.

Handling Divergent amend
----------------------------------------------

We can detect that multiple diverging amendments have been made.
The `evolve` command can solve this situation. But all corner case are not
handled now.

This section needs to be written.
