openstack/nova - nova - OpenDev: Free Software Needs Free Tools

With the potential use of entry points, code from the current tree needs to
be installed into a venv created by install_venv.py via setup.py develop.
This will ensure that the appropriate meta-data and paths are set in the
virtualenv.

The most recent version of pip (1.2.1 as of a couple days ago) fails
to install the required Nova .venv packages. Nailing the installed
pip version when using run_tests.sh seems like a reasonable solution
to this issue.
Fixes LP Bug #1047120.

This required rewriting our Diffie-Hellman-Merkle implementation for
set_admin_password in xen. Fixes bug 917851.

Rather than just giving users the sudo password prompt immediately,
actually tell them what is about to be installed, so they know
whether it is reasonable to be entering their password.

This simplifies a number of Jenkins jobs which currently, other
than directory names, could be the same for all OpenStack
projects. By renaming the virtualenv directory, the redundant
Jenkins virtualenv build and copy jobs can be eliminated.

Ubuntu Oneiric has a problem with the pip installed version of m2crypto.
This fix installs python-m2crypto via apt-get on Oneiric.

Looks like the fix for #884915 only works with RHEL6. Make it work
correctly on Fedora 16.

This adds a patch to fix the broken eventlet code that's installed in the

Added a flag to run_tests.sh to allow user to optionally install venv with --no-site-packages.
This fixes bug 880905

When you create a virtualenv, pip and setuptools/distribute is
installed.
When we later run install_venv.py to update the venv, we should
be sure to grab the latest versions of pip and distribute otherwise
issues like this one are masked:

... so use the system m2crypto library instead.
M2Crypto won't build on Fedora because of some bizarre differences with
Fedora's OpenSSL headers. I can get it to build by doing e.g.
 $> python ./tools/install_venv.py
 $> cd .nova-venv/build/M2Crypto
 $> for i in SWIG/_ec.i SWIG/_evp.i; do sed -i -e "s/opensslconf/opensslconf-x86_64/" $i ; done
 $> cd -
 $> SWIG_FEATURES=-cpperraswarn ./tools/with_venv.sh pip install M2Crypto
but that's clearly no fun. It should be fine to just use the system
version.

... and use it to install virtualenv with yum if it's not available.

libvirt isn't listed in pip-requires because (a) it's not in PyPi and
(b) you always want to use libvirt's python bindings that matches the
version of libvirt installed on the system.
Currently, running nova-compute in virtualenv fails because libvirt
can't be imported. The --no-site-packages flag is what prevents this.
Everything seems to work fine without it. To verify, try deleting the
no-global-site-packages.txt from your .nova-venv.

Subsequent runs of install_venv.sh should upgrade packages to the
latest available.

We don't need to pass the -E argument since we're already running
inside the virtualenv.

more user-friendly and not depend on PIP while not in the virtual
environment.

Also added some more instructive messages to install_venv.py, because otherwise people that don't know what they're doing will install the wrong pip... i.e. I did :-)

Also adds some tools for dealing with virtualenvs to the tools
directory.
