Add .flake8 configuration file enabling show_source and statistics. This
makes flake8 output more useful for handling bug reports like:
https://gitlab.com/nbdkit/libnbd/-/issues/4
For example I added some bad changes:
$ sh pycodestyle.sh
...
python/nbdsh.py:20:1: F401 'unused' imported but unused
import unused

python/nbdsh.py:22:1: E302 expected 2 blank lines, found 1

"""

I suspect this will be ignored if we're using srcdir != builddir (not
that this works at the moment). The documentation is confusing about
how exactly the file is found mentioning only the "project" directory
whatever that means.
https://flake8.pycqa.org/en/latest/user/configuration.html
Should we add the equivalent command line parameters instead?
Anyway, as it's only optional configuration, ACK.

I suspect this will be ignored if we're using srcdir != builddir (not
that this works at the moment). The documentation is confusing about
how exactly the file is found mentioning only the "project" directory
whatever that means.
I think .flake8 file is searched in the directories where the source is,
so this should work also in out of tree builds. This works for me for pytest
in another project using out of tree build.
https://flake8.pycqa.org/en/latest/user/configuration.html
Should we add the equivalent command line parameters instead?
We can, but using a configuration file makes it easier to document why
certain configuration is used. For example why you want to disable certain
checks.
When you have a configuration file, you can actually drop the pycodestyle.sh
script, since running flake8 /path/to/dir is enough to check all the *.py files
under that tree.
Anyway, as it's only optional configuration, ACK.

We'll have to keep pycodestyle.sh because it checks if flake8 is
available before running it.
I'm still happy with the original patch if you wish to push it.

We'll have to keep pycodestyle.sh because it checks if flake8 is
available before running it.
This is another issue, running a random version of flake8 from the
host means it will
fail each time flake8 changes the rules (we have suffered from this a
lot in the last 7 years).
I added more info about this here:
https://gitlab.com/nbdkit/libnbd/-/issues/4#note_559832296
I'm still happy with the original patch if you wish to push it.
I'll push it, thanks.
