test: adapt test to less frequent branch warning

The 701df761aa94 changeset in mercurial core made the branch warning issue only
for the first branch created. We adapt the tests to reflect this change.

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

(amend of public changeset denied)

  $ 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'

  $ hg up 'desc(a1)'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -m 'a1_'

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 ?)

Evolve disables active bookmarks.

  $ hg up 10
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg bookmark testbookmark
  $ ls .hg/bookmarks*
  .hg/bookmarks
  .hg/bookmarks.* (glob)
  $ hg evolve

  (leaving bookmark testbookmark)
  working directory is now at f37ed7a60f43
  $ ls .hg/bookmarks*

  $ echo "hello world" > newfile
  $ hg add newfile
