Detailed tests of gitsvn aspects of git.py
==========================================

.. :doctest:
.. :setup: zest.releaser.tests.functional.setup
.. :teardown: zest.releaser.tests.functional.teardown

Some initial imports:

    >>> from zest.releaser import git
    >>> from zest.releaser.utils import execute_command
    >>> import os

Project name
------------

The prepared git project has a setup.py, so the name in there is used:

    >>> os.chdir(gitsvnsourcedir)
    >>> checkout = git.Git()
    >>> checkout.name
    'tha.example'

When the setup.py doesn't exist or doesn't return a proper name, we fall back
to the directory name.

    >>> orig = checkout.get_setup_py_name
    >>> checkout.get_setup_py_name= lambda: None  # Hack
    >>> checkout.name
    'tha.example-gitsvn'
    >>> checkout.get_setup_py_name = orig  # Restore hack


Diff and commit
---------------

Make a change:

    >>> setup_py = os.path.join(gitsvnsourcedir, 'setup.py')
    >>> dont_care = open(setup_py, 'a').write('\na = 2\n')
    >>> cmd = checkout.cmd_diff()
    >>> cmd
    'git diff'
    >>> print(execute_command(cmd))
    diff --git a/setup.py b/setup.py
    index 9c14143..54fa3b9 100644
    --- a/setup.py

               ]},
           )
    +
    +a = 2

Commit it:

    >>> cmd = checkout.cmd_commit('small tweak')
    >>> cmd
    'git commit -a -m "small tweak"'

In some cases we get this output:
``[master ...] small tweak``
and in other this:
``Created commit ...: small tweak``

    >>> print('dummy %s' % execute_command(cmd))
    dummy...small tweak

Tags
----

Originally there are no tags:

    >>> checkout.available_tags()
    []

Create a tag and it will show up (master diverges from trunk):

    >>> cmds = checkout.cmd_create_tag('0.1')
    <BLANKLINE>
    EXPERIMENTAL support for git-svn tagging!
    <BLANKLINE>
    You are on branch master.
    Your local master diverges from trunk.
    <BLANKLINE>
    >>> cmds
    ['git svn dcommit',
     'git tag 0.1 -m "Tagging 0.1"',
     'git svn tag -m "Tagging 0.1" 0.1']
    >>> for cmd in cmds:
    ...     dont_care = execute_command(cmd)
    >>> checkout.available_tags()
    ['0.1']

Create a tag and it will show up (master == trunk):

    >>> cmds = checkout.cmd_create_tag('0.2')
    <BLANKLINE>
    EXPERIMENTAL support for git-svn tagging!
    <BLANKLINE>
    You are on branch master.
    >>> cmds
    ['git tag 0.2 -m "Tagging 0.2"',
     'git svn tag -m "Tagging 0.2" 0.2']
    >>> for cmd in cmds:
    ...     dont_care = execute_command(cmd)
    >>> checkout.available_tags()
    ['0.1', '0.2']

Work on a branch different from master (unsupported):

    >>> dontcare = execute_command('git checkout -b foo')
    >>> cmds = checkout.cmd_create_tag('0.3')
    Traceback (most recent call last):
    ...
    RuntimeError: SYSTEM EXIT (code=1)
    >>> checkout.available_tags()
    ['0.1', '0.2']
