Fixed. It was a regex error.

Hi Martin,

As discussed, here is a new version with pep8-related fixes

Hi Martin,

Already noticed that. Implemented the named groups as Tomas advised.
Added the third test for

Thank you for patch, I have a few nitpicks:

1)
On 10/08/15 13:05, Oleg Fayans wrote:
+def create_segment(master, leftnode, rightnode):

Why do you add the name of method in docstring?
My bad, fixed.

still there

+        tokenize_topologies(command_output)
+        takes an output of `ipa topologysegment-find` and
returns an
array of

Fixed, sorry.



2)

+def create_segment(master, leftnode, rightnode):
+    """create_segment(master, leftnode, rightnode)
+ creates a topology segment. The first argument is a node to
run the
command on
+    The first 3 arguments should be objects of class Host
+ Returns a hash object containing segment's name, leftnode,
rightnode information
+    """

I would prefer to add assert there instead of just document
that a
Host
object is needed
assert(isinstance(master, Host))
...

Fixed. Created a decorator that checks the type of arguments

This does not scale well.
If we will want to add new argument that is not host object, you
need
change it again.

Agreed. Modified the decorator so that you can specify a slice of
arguments to be checked and a class to compare to. This does
scale :)

This might be used as function with specified variables that
have to be
host objects


3)
+def destroy_segment(master, segment_name):
+    """
+    destroy_segment(master, segment_name)
+    Destroys topology segment. First argument should be
object of
class
Host

Instead of description of params as first, second etc., you
may use
following:

+def destroy_segment(master, segment_name):
+    """
+    Destroys topology segment.
+    :param master: reference to master object of class Host
+    :param segment: name fo segment
and eventually this in other methods
+    :returns: Lorem ipsum sit dolor mit amet
+    :raises NotFound: if segment is not found

Fixed

4)

cls.replicas[:len(cls.replicas) - 1],

I suggest cls.replicas[:-1]

In [2]: a = [1, 2, 3, 4, 5]

In [3]: a[:-1]
Out[3]: [1, 2, 3, 4]

Fixed

5)
Why re.findall() and then you just use the first result?
'leftnode': self.leftnode_re.findall(i)[0]

Isn't just re.search() enough?
leftnode_re.search(value).group(1)

in fact
leftnode_re.findall(string)[0]
and
leftnode_re.search(string).group(1),
Are equally bad from the readability point of view. The first
one is
even shorter a bit, so why change? :)

It depends on point of view,  because when I reviewed it
yesterday my
brain raises exception that you are trying to add multiple
values to
single value attribute, because you used findall, I expected
that you
need multiple values, and then I saw that index [0] at the end,
and I
was pretty confused what are you trying to achieve.

And because findall is not effective in case when you need to
find just
one occurrence.

I got it. Fixed.






Python 3 nitpick:
I'm not sure if time when we should enforce python 2/3
compability
already comes, but just for record:
instead of open(file, 'r'), please use io.open(file, 'r')
(import io
before)

Done.





1)

+#

empty comment here (several times)

Removed



NACK

you changed it wrong

group() returns everything, you need use group(1) to return
content in
braces.

















Please, do not use third-party URL shorteners from within our source code.
