hacking/flake8 skips most xenapi plugins

[Johannes Erdfelt]

It appears to be because the plugins themselves don't have a filename that ends in .py so they get skipped. Only the few files in there that end .py are being checked.

Arg, this keeps breaking...

Change abandoned by Michael Davies (<email address hidden>) on branch: master
Review: https://review.openstack.org/99588
Reason: So with more testing, this approach clearly doesn't work :(

[Michael Davies (mrda)]

Specifying a path to check is orthogonal to specifying a filename match.

i.e. filename = *.py,*plugins/xenserver*

This specified that all *.py files will be checked from the <root> of the tox command downwards, and all *.py files in a directory that matches *plugins/xenserver*.

I can't seem to get *plugins/xenserver* to match all files under that directory. Or more specifically, all files under plugins/xenserver/xenapi/etc/xapi.d/plugins

Consequently I'm unassigning in case anyone else has better ideas.

The only other option, is to rename all those files in that directory to have a .py suffix. That'd work for sure.

flake8 doesn't do path matching, it does a walk. So you can only do file level matching. I did look at this code recently for just this issue.

    plugins/xenserver: Resolve PEP8 issues

    Before enabling PEP8 checks for these files, the actual PEP8 issues
    need to be resolved. There are a number of "types" of issues that need
    to be fixed:

    * E112 expected an indented block
    * E241 multiple spaces after ','
    * E265 block comment should start with '# '
    * E302 expected 2 blank lines, found 1
    * H102 Apache 2.0 license header not found
    * H237 module module is removed in Python 3
    * H303 No wildcard (*) import.
    * H404 multi line docstring should start without a leading new line
    * H231 Python 3.x incompatible 'except x,y:' construct
    * F403 from module import *' used; unable to detect undefined names
    * F841 local variable 'name' is assigned to but never used
    * N344 Use six.iteritems() instead of dict.iteritems().

    The fixes for the above are all pretty self-explanatory, but there is
    one exception. The 'N344' issues are not ignorable due to how the
    "hacking" check is implemented. Rather than ignoring them, skip the
    issue altogether by replacing 'iteritems' with 'items'. The difference
    in memory usage that this incurs should not be noticable.

    plugins/xenserver: Resolve PEP8 issues

    Some files have regressed since '798058' ensured PEP8 compliance.
    Correct these regressions in preparation for enabled PEP8 checks.

    plugins/xenserver: Add '.py' extension

    All Python files, except executables, should have a '.py' extension.
    This wasn't being done for files in the 'plugins/xenserver' folder,
    likely because it seems unnatural to call a "plugin" with a file
    extension.

    Begin working towards a resolution for this by renaming all files to
    include a '.py' extension. To avoid forcing operators to upgrade the
    Nova service and per-host plugins at the same time, continue to
    reference the old, non-'.py' filenames, using symlinks to ensure the
    references continue to work. Once Ocata has been released, these
    symlinks can be removed, the API version updated and the reference
    updated to include the '.py' extension.
