This is an archive for Connexions documents. It holds published documents and collections of documents. It is accessible to the public via a read-only API. It has an optional write API for publishing content from an unpublished repository (e.g. rhaptos2.repo).

This installation procedure attempts to cover two platforms, the Mac and Debian based systems. If you are using a platform other these, attempt to muddle through the instructions, then feel free to either file an issue or contact Connexions for further assistance.

Install the PostgreSQL database ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This will require a PostgreSQL install that is greater than or equal to version 9.3. We have two postgres extension dependencies: plpythonu and plxslt.

On a Mac, use the PostgresApp.

On Debian (and Ubuntu), issue the following command:

apt-get install postgresql-9.3 postgresql-server-dev-9.3 postgresql-client-9.3 postgresql-contrib-9.3 postgresql-plpython-9.3

Verify the install and port by using pg_lscluster. If the 9.3 cluster is not the first one installed (which it likely is not), note the port and cluster name. For example, the second cluster installed will end up by default with port 5433, and a cluster named main.

Set the PGCLUSTER environment variable to make psql and other postgresql command line tools connect to the appropriate server. For the example above, use:

export PGCLUSTER=9.3/main

The plpythonu extension comes with the PostgresApp, which you don't have to install this one manuallly. We've included the postgresql-plpython package in the previous installation command, for Debian and Ubuntu.

The plxslt package can be found on github at petere/plxslt). You'll need to build and install this package manually.

On a Mac, this can be done using the following commands, assuming you have both PostgresApp and homebrew installed.

brew install libxml2 libxslt
which psql # Make sure this returns: /Applications/Postgres93.app/Contents/MacOS/bin/psql
           # Otherwise, you may need to add this path to ~/.profile
git clone https://github.com/petere/plxslt
cd plxslt
export PKG_CONFIG_PATH=/usr/local/opt/libxml2/lib/pkgconfig:/usr/local/opt/libxslt/lib/pkgconfig
make && make install
cd ..

On a Debian based system, the installation is as follows:

apt-get install libxml2-dev libxslt-dev
git clone https://github.com/petere/plxslt
cd plxslt
make && make install
cd ..

The default settings for the database are setup to use the following credentials:

database-name

cnxarchive

database-user

cnxarchive

database-password

cnxarchive

If you decided to change any of these default values, please ensure you also change them in the application's configuration file, which is discussed later in this instructions.

To set up the database, issue the following commands (these will use the default cluster, as defined above):

psql -U postgres -d postgres -c "CREATE USER cnxarchive WITH SUPERUSER PASSWORD 'cnxarchive';"
createdb -U postgres -O cnxarchive cnxarchive

OSX Note: You may need to create the postgres user: psql -d postgres -c "CREATE USER postgres WITH SUPERUSER;"

Note: cnx-archive requires the packages in this section to be installed with the system python. Specifically it needs to be installed to the python that postgresql uses for python triggers.

OSX Development Note: (Use at your own risk!) Instead of installing system python packages (so Postgres has access to them) you can link your virtualenv site-packages directory to your Home sitepackages dir:

# Create the virtualenv dirs
virtualenv .
# Note: replace `getusersitepackages` with `getsitepackages[-1]` if postgres is not running as you
USER_SITEPACKAGES=$(python -c 'import site;print(site.getusersitepackages())')
# Make sure the user/system site-packages dir exists.
mkdir -p ${USER_SITEPACKAGES}
# Link the virtualenv site-packages to the user/system
ln -s ./lib/python2.7/site-packages ${USER_SITEPACKAGES}
# Start up the virtualenv
source bin/activate
# Follow the steps below

Before installing cnx-archive, you need to first install the dependencies that have not been released to the public package repositories:

git clone https://github.com/Connexions/cnx-query-grammar.git
cd cnx-query-grammar
python setup.py install
cd ..

git clone https://github.com/Connexions/rhaptos.cnxmlutils.git
cd rhaptos.cnxmlutils
python setup.py install
cd ..

# Install bug-fixes branch of plpydbapi
git clone -b bug-fixes https://github.com/Connexions/plpydbapi.git
cd plpydbapi
python setup.py install
cd ..

To install the application itself:

python setup.py install

This will install the package and a few application specific scripts. One of these scripts is used to initialize the database with the applications schema. :

initialize_cnx-archive_db development.ini

You can optionally pass --with-example-data to the database initialization command, which will populate the database with a small set of content.

To run the application, use the paste script with the serve command. (The paste script and serve command come from PasteScript and PasteDeploy, respectively.)

This example uses the development.ini, which has been supplied with the package. If you changed any of the database setup values, you'll also need to change them in the configuration file.:

paster serve development.ini

You can then surf to the address printed out by the above command.

The tests use the standard library unittest package and can therefore be run with minimal effort. Make a testing config, such as testing.ini, and set the environment variable TESTING_CONFIG to the name of that file:

export TESTING_CONFIG=testing.ini

Then, either of the following will work:

$ python -m unittest discover
$ python setup.py test

This uses example data found in the test-data directory.
