Creating And Updating Changeset
===============================

Setup the Base Repo
-------------------

We start with a plain base repo::

  $ hg init main; cd main
  $ cat >main-file-1 <<-EOF
  > One
  > 
  > Two
  > 
  > Three
  > EOF
  $ echo Two >main-file-2
  $ hg add
  adding main-file-1
  adding main-file-2
  $ hg commit --message base
  $ cd ..

and clone this into a new repo where we do our work::

  $ hg clone main work
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd work


Create First Patch
------------------

To begin with, we just do the changes that will be the initial version of the changeset::

  $ echo One >file-from-A
  $ sed -i'' -e s/One/Eins/ main-file-1
  $ hg add file-from-A

So this is what we would like our changeset to be::

  $ hg diff
  diff --git a/file-from-A b/file-from-A
  new file mode 100644
  --- /dev/null
  +++ b/file-from-A
  @@ -0,0 +1,1 @@
  +One
  diff --git a/main-file-1 b/main-file-1
  --- a/main-file-1
  +++ b/main-file-1
  @@ -1,1 +1,1 @@
  -One
  +Eins

To commit it we just - commit it::

  $ hg commit --message "a nifty feature"

and place a bookmark so we can easily refer to it again (which we could have done before the commit)::

  $ hg book feature-A


Create Second Patch
-------------------

Let's do this again for the second changeset::

  $ echo Two >file-from-B
  $ sed -i'' -e s/Two/Zwie/ main-file-1
  $ hg add file-from-B

Before committing, however, we need to switch to a new bookmark for the second
changeset. Otherwise we would inadvertently move the bookmark for our first changeset.
It is therefore advisable to always set the bookmark before committing::

  $ hg book feature-B
  $ hg commit --message "another feature (child of $(hg log -r . -T '{node|short}'))"

So here we are::

  $ hg book
     feature-A                 1:568a468b60fc
   * feature-B                 2:73296a82292a


Fix The Second Patch
--------------------

There's a typo in feature-B. We spelled *Zwie* instead of *Zwei*::

  $ hg diff --change tip | grep -F Zwie
  +Zwie

Fixing this is very easy. Just change::

  $ sed -i'' -e s/Zwie/Zwei/ main-file-1

and **amend**::

  $ hg amend

This results in a new single changeset for our amended changeset, and the old
changeset plus the updating changeset are hidden from view by default::

  $ hg log
  4	feature-B: another feature (child of 568a468b60fc) - test
  1	feature-A: a nifty feature - test
  0	: base - test

  $ hg up feature-A -q
  $ hg bookmark -i feature-A
  $ sed -i'' -e s/Eins/Un/ main-file-1

  $ hg phase --public 0 -v
  phase changed for 1 changesets

Test branch preservation:
===========================

  $ hg init evolving-branch
  $ cd evolving-branch
  $ touch a
  $ hg add a
  $ hg ci -m 'a0'
  $ echo 1 > a
  $ hg ci -m 'a1'
  $ echo 2 > a
  $ hg ci -m 'a2'
  $ echo 3 > a
  $ hg ci -m 'a3'

  $ hg log -G --template '{rev} [{branch}] {desc|firstline}\n'
  @  3 [default] a3
  |
  o  2 [default] a2
  |
  o  1 [default] a1
  |
  o  0 [default] a0
  

branch change propagated

  $ hg up 'desc(a2)'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch mybranch
  marked working directory as branch mybranch
  (branches are permanent and global, did you want a bookmark?)
  $ hg amend
  1 new unstable changesets

  $ hg evolve
  move:[3] a3
  atop:[5] a2
  working directory is now at 7c5649f73d11

  $ hg log -G --template '{rev} [{branch}] {desc|firstline}\n'
  @  6 [mybranch] a3
  |
  o  5 [mybranch] a2
  |
  o  1 [default] a1
  |
  o  0 [default] a0
  

branch change preserved

  $ hg up 'desc(a1)'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -m 'a1_'
  2 new unstable changesets
  $ hg evolve
  move:[5] a2
  atop:[7] a1_
  working directory is now at 5406c5cfee42
  $ hg evolve
  move:[6] a3

  working directory is now at c7661e655801
  $ hg log -G --template '{rev} [{branch}] {desc|firstline}\n'

Evolve from the middle of a stack pick the right changesets.

  $ hg up 7
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg ci --amend -m 'a1__'
  2 new unstable changesets

  $ hg up 8
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg evolve
  nothing to evolve here
  (2 troubled changesets, do you want --any ?)
