[Kimchi-devel] [PATCH v3 1/2] bugfix: Fix regexp in "kimchi.utils.get_next_clone_name"

[Crístian Viana]

The regular expression used in the function
"kimchi.utils.get_next_clone_name" has an extra '-' which
isn't needed.

The following commands, executed from an interactive Python shell,
demonstrate the bug:

>>> from kimchi.utils import get_next_clone_name
>>> get_next_clone_name(['foo'], 'index', '.html')
u'index-clone-1.html'
>>> get_next_clone_name(['foo', 'index-clone-1.html'], 'index', '.html')
u'index-clone-1.html'

Even though the name 'index-clone-1.html' is provided as an existing
name, the function still returns a duplicate value.

Fix the regular expression by removing an unnecessary character.

The following commands demonstrate the bug fix:

>>> from kimchi.utils import get_next_clone_name
>>> get_next_clone_name(['foo'], 'index', '.html')
u'index-clone-1.html'
>>> get_next_clone_name(['foo', 'index-clone-1.html'], 'index', '.html')
u'index-clone-2.html'
>>> get_next_clone_name(['foo', 'index-clone-1.html', 'index-clone-2.html'], 'index', '.html')
u'index-clone-3.html'
