Guru Meditation Reports (GMR) code in oslo.reports was recently updated
to expect SIGUSR2 as opposed to SIGUSR1, because it is reserved by
Apache 'mod_wsgi' for its own use.
Signal was changed and merged in change:

This patch proposes a thorough update to the development doc
for the volume migration. Several improvements to volume
migration have been made during the last development cycle
and this patch attempts to document the current state.

The first pass at setting up config entries for
replication targets was a hacky custom string parser
with its own unique syntax.
A better option is to use oslo.cfg's MultiOpt in conjunction
with Dict types so we can eliminate quite a bit of custom
parsing and most importantly use a standard syntax for conf
entries to make things easy for admins and reduce the
probability of syntax errors and mistakes in config setttings.

One thing that may be needed by some back ends
that are implementing replication is some sort
of back end device identifier.
For managed back ends this shouldn't be an issue
but for unmanaged, it's handy to have some sort
of identifier string.
This patch just adds that to the response examples
in the volume.manager code as well as adds an update
to the dev docs to point it out.

This adds a scaled back replication implementation
that leaves the bulk of the work up to the driver.
We just provide basic admin API methods to do things
like enable/disable and fail-over. Set up and
specification of replication targets for a specific
back end are now intended to be part of the cinder.conf
in the driver section itself.
Replication targets are configured via the cinder.conf
file in their associated driver section. See the devref
doc included in this commit for details on the format.
The next step in configuration is to create a volume-type
with replication info in the extra-specs.
extra-specs = replication=enable, volume_backend_name=foo
This instructs the driver to utilize replication, default is
up to the driver but would suggest single way rep and in the case
of multiple targets, driver could choose or have a default.
If the back end doesn't report replication=enabled in it's stats
updates the scheduler will fail to place the volume due to invalid
host, or no hosts available.
Vendors can easily modify extra-specs or their own config settings
to modify this behavior, any vendor-unique adaptation can be
provided through the use of scoped keys. Suggested examples
will be published in docs.

Simple update for our painfully out of date devref docs.
Just a short refresh on unit_tests, there's a lot that could
and probably should be added there, but this change just gets
rid of the obsolete references to Nose and adds info regarding
tox and how to use it.

The Guru Meditation Reports has graduated from oslo-incubator, Cinder
should switch to use oslo.reports to keep the code base clean.

This commit integrates functionality from the
`openstack.common.report` module into Cinder.
This enables Cinder services to receive SIGUSR1
and print a Guru Meditation Report to stderr.
The required modules were added to
'openstack-common.conf' as well.
It is essentially a copy from implementation of
nova side.

This patch removes the implementation of ChanceScheduler and SimpleScheduler
as previous changes have made sure they are internally replaced by
FilterScheduler.
The "max_gigabytes" config option is deprecated and will leave it like that
for one more release before we can remove it.

their implementation have been removed from Cinder."

Syncs these two commits from oslo-incubator:
Support overriding oslo localedir too
Add a gettextutils.install() helper function
to get a new gettextutils.install() function which allows the default
localedir to be overwritten via an environment variable.
Note that gettextutils.install() must be called before any other cinder
modules are imported since some modules attempt to translate strings
at import time (e.g. in cinder.flags). This is broken and inefficient,
but fixing it involves adding something like sphinx's l_() function and
would be very invaisve.
Change-Id: I86562b3a65d371673bb21f7179eecc7602bc0775
The gettext.install() function installs a builtin _() function which
translates a string in the translation domain supplied to the install()
function. If gettext.install() is called multiple times, it's the last
call to the function which wins and the last supplied translation domain
which is used e.g.
>>> import os
>>> os.environ['LANG'] = 'ja.UTF-8'
>>> import gettext
>>> gettext.install('keystone', unicode=1, localedir='/opt/stack/keystone/keystone/locale')
>>> print _('Invalid syslog facility')
n無効な syslog ファシリティ
>>> gettext.install('cinder', unicode=1, localedir='/opt/stack/nova/cinder/locale')
>>> print _('Invalid syslog facility')
Invalid syslog facility
Usually this function is called early on in a toplevel script and we
assume that no other code will call it and override the installed _().
However, in Cinder, we have taken a shortcut to avoid having to call it
explicitly from each script and instead call it from cinder/__init__.py.
This shortcut would be perfectly fine if we were absolutely sure that
nova modules would never be imported from another program. It's probably
quite incorrect for a program to use cinder code (indeed, if we wanted
to support this, Cinder code shouldn't use the default _() function) but
nevertheless there are some corner cases where it happens. For example,
the keystoneclient auth_token middleware tries to import cfg from
cinder.openstack and this in turn causes gettext.install('cinder') in
other projects like glance or quantum.
To avoid any doubt here, let's just rip out the shortcut and always
call gettext.install() from the top-level script.
However, there's a bit of an annoying detail here - by default,
nosetests starts in the current directly and tries to import all modules
it finds to look for tests. Without the _() builtin installed, importing
some modules like cinder.flags will fail.
Since it only ever makes sense to load tests from the cinder/tests dir,
we can ask nose to do that by using the --tests argument via setup.cfg.
Note, this means that if you previously did this:
$> tox -- cinder.tests.foo cinder.tests.bar
then you must now do this:
$> tox -- --tests cinder.tests.foo,cinder.tests.bar

Way back when Cinder was inagurated as a separate project, the docs
directory from Nova was used as a seed for the one in the Cinder repo
This patch is simply cleaning out images and files which have no
relation to Cinder at all, and are at best extremely outdated when
applied to Nova.
Aside from the deletions which are mainly images, and files related
to the configuration of CloudPipe, there is one modification to
conf.py which simply removes a reference to a vmware doc that no
longer exists.
