[bitbake-devel][PATCH V2 1/5] fetch2/git.py: add filter_regex parameter to latest_versionstring

[Qi.Chen]

From: Chen Qi <Qi.Chen@windriver.com>

We want to be able to do stable version upgrade for recipes. For
example, 1.0.0 -> 1.0.1 instead of 1.0.0 -> 1.1.0.

To to this, we need an extra paramter to latest_versionstring
so that we are able to filter out the versions we need. Using regex
has the advantage of adapting to different version schemes.

This needs to include a note explaining that filter_regex is derived
from PV, and so uses . as separator, while upstream may be using _ as
separator (as seen below in the code where the same conversion happens
before the discovered version is returned).

Here and in other places you can perhaps simply pass in filter_regex
without naming the argument?

This could also use list comprehension:

if filter_regex:
    versions = [v for v in versions if re.match(filter_regex, v[1])]

You can even form the list with a single statement by setting the
condition like this:

... if not filter_regex or re.match...

but doing list comprehension twice is perhaps more clear.
