This extension does not work anymore and is not maintained upstream.

Fixes #953

This enables gnocchi-amqp daemon.

Which listens to metrics from collectd amqp1 write plugin.

This from the old Zuul gate.

See https://github.com/Pylons/webob/issues/355

All pbr interesting features (the seutp.cfg) have been implemented in
setuptools since version 30.3.0 (8 Dec 2016).
Also pbr will break us soon and force us to found a new solution
to generate things during setup.py steps.
https://github.com/gnocchixyz/gnocchi/issues/755

When you use pbr you cannot override most of the cmdclass. So we cannot
make our hooks working anymore.

Generation of ChangeLog and AUTHORS are done during egg_info.
gnocchi-api script is created on the fly with the right python header

Package file listing and package version is done by the pypa maintained
setuptools_scm.

This may impact downstream packaging as setuptools versions are a bit
old:
* xenial: 20.7
* zesty: 33.1.1
* centos7/rhel7: 0.9.8 ... really ?
* rdo queen: 22.0
* rdo rocky plan to 38.6

Closes-bug: #755

By default tox built a sdist with the python OS packages. We already
skip install/develop phase and manually use "pip install -e"
The sdist is useless and skipping it allow to run tox on old OS
that doesn't have a recent setuptools.

We use environment marker in requirement so we need at least
setuptools 20.6.8.

This must be a setup_requires because pbr use setuptools to read the
requirement.

This is not tested and not widely used.

We current install Gnocchi twice, once with no extra and develop mode,
and a second time with extra but without develop mode.

This change install gnocchi only once with extra and develop mode.

The docs target is run in Travis so we should be good. No need to run it here.

Fixes: #614

i believe i figured out how percentile is computed. this does
something very similar to median (for obvious reasons). at highlevel:
- get the index the percentile would land on and assume it falls
between indices
- take the values of the indices it falls between and figure out
weight of each value.
- handle the percentiles that fall on an exact index.

this is ~30x better. it's actually a bit slower (3%-5%?) than the
median computation so it's debatable if we want to remove median code.

drop scipy. also remove numpy.lib.recfunctions as it doesn't seem to
used anywhere.

There's no reason to stick with Python 2 for this job.

We cannot move docs-gnocchi.xyz yet to Python 3 because older branch do not
work with Python 3 doc.

py27-gate is not used anymore and I don't think anyone uses py27-gabbi, you can
just filter the test by name easily.

Now that the `ceph` flavor is gone, let's use `ceph` for the recommended
approach and `ceph_alternative` for the other one.

To enable warning as error, this changes
* Remove empty 2.1 and 2.2 release notes
* Add a hack to make pkg_resource find local entry_point
* Add a script to check all versions are linked on the main page
* Ensure logo is the latest

The rest page of the stable branch is missing

We remove retrying from our deps, but miss to put it in docs-gnocchi.xyz

This change fixes that.

By default, daiquiri output is hidden. The side effect is
that some sphinx error are not printed.

This change fixes that.

Those version are now one year old. I don't think there's any user left.

We have a dedicated tool that can be run in any standard installation of
Gnocchi, not need for a hackish tox target anymore.

Putting `envdir = upgrade` makes tox create an upgrade in the middle of the
source directory, which is not convenient/standard and gets scanned by e.g.
flake8. Let's each job use its own default directory.

So we have uwsgi pulled.

- Rename running to operating
- Mention aggregation methods in archive policies
- Add a comparison table

Oslotest is OpenStack specific and we actually don't use any of its feature
except stdout redirection and log silencing, which is really provided by
`fixtures' and `daiquiri'.
Remove it and use testtools directly. This avoids having OS_* variables used
everywhere and makes sure we don't pull dependencies we don't need (mox3,
os-client-config, etc).

That'll simplify the dev workflow and Travis jobs number.
