opentree

This is the repository for the Open Tree of Life web applications, one of many subsystems making up the Open Tree of Life project code.

For Open Tree of Life documentation, see the germinator repository's wiki. The 'deployment system' and web API documentation sources that formerly resided in this repository now live in the germinator repository.

The following instructions have not been reviewed in a long time. For local installation a better place to start might be this wiki page.

Installation

See the phylografter instructions for more details about using web2py.

We strongly recommend using a virtual environment to manage the version of Python and installed modules. We're currently running opentree with Python v2.7.3. Newer versions of python2.7 should work, but NOTE that web2py is not compatible with Python 3.

If necessary, compile Python2.7 and use it when making your virtualenv. You should be able to safely install multiple versions of python using your preferred package manager, or by configuring Python2.7 with the --prefix option and 'make altinstall'.

So the final invocation to create your virtualenv should look something like:

$ virtualenv --python=/usr/bin/python2.7 --distribute <path/to/new/virtualenv/>

Or, if you're using virtualenvwrapper (http://virtualenvwrapper.readthedocs.org/en/latest/index.html):

$ mkvirtualenv --python=python2.7 --no-site-packages --distribute opentree

The included requirements.txt file lists known-good versions of all the required python modules for opentree, plus a few convenience modules. To install these modules using pip,

pip install -r requirements.txt

The contents of the webapp subdirectory are a web2py application. Make a symbolic link called "opentree" in a web2py/applications directory to the webapp directory. You should be able to launch web2py and see the app running at http://127.0.0.1:8000/opentree/

There is now a second web2py app for the curation tool, which will also need a symlink. This will be available at http://127.0.0.1:8000/curator/

Briefly:

1. Download and unpack the source code version of web2py from http://www.web2py.com/examples/default/download MTH used version 2.4.2 of web2py

   NOTE: This version of web2py includes basic support for OAuth 2.0, but it needs a minor patch to support for login via the GitHub API v3. (The curation app uses GitHub for its datastore and attribution. The tree browser also uses it for its issue tracker, with optional authentication for convenience.) Replace this web2py file with a modified version in the same folder as this README:

   {web2py-2.4.4}/gluon/contrib/login_methods/oauth20_account.py
   

2. Create the sym links for the main web app and the study curation tool.

   cd web2py/applications
   ln -s /full/path/to/opentree/webapp opentree
   ln -s /full/path/to/opentree/curator curator
   

3. Customize web2py's site-wide routing behavior using "SITE.routes.py"

   # return to main web2py directory
   cd ..  
   cp /full/path/to/opentree/SITE.routes.py routes.py
   

   This routing file works in tandem with the opentree app router and lets us have proper URLs with hyphens instead of underscores.

4. Launch web2py

   cd /full/path/to/web2py
   python web2py.py --nogui -a '<recycle>'
   

   Where the -a flag is allowing you to reuse the previous admin password that you used with this instance of web2py.

   To test with login and proper domain name, modify your test system's /etc/hosts file (or equivalent) to resolve the domain devtree.opentreeoflife.org to localhost (127.0.0.1). Then run web2py on (privileged) port 80 like so:

   cd /full/path/to/web2py
   sudo python web2py.py --nogui -p 80 -a '<recycle>'
   

   To test with local HTTPS, modify your test system's /etc/hosts file as described above, then use a [web2py options file]() to support HTTP traffic on port 80 and HTTPS on port 443. This requires working key and cert files. to localhost (127.0.0.1). Then run web2py on (privileged) port 80 like so:

   cd /full/path/to/web2py
   sudo python web2py.py --verbose -L multiport_options.py
   

   This looks for the options file multiport_options.py in the same directory as web2py.py, with contents something like this:

   import os 
   interfaces = [(
                   '0.0.0.0',
                   80
                ),
                (
                   '0.0.0.0',
                   443,
                   '/Volumes/SecureFiles/.ssh/opentree/ssl-keys/opentreeoflife.org.key',
                   '/Volumes/SecureFiles/.ssh/opentree/ssl-keys/STAR_opentreeoflife_org.crt'
                )]
   password = '' 
   pid_filename = 'httpserver.pid' 
   log_filename = 'httpserver.log' 
   folder = os.getcwd() 
   

   Now you should be able to use production domain names, secure connections, and OAuth as in the production setup.

Subdirectories

mockup : JAR's hand-written html that mock up the design of the site.

smasher : construction of synthetic taxonomy. See https://github.com/OpenTreeOfLife/opentree/wiki/Open-Tree-Taxonomy for details

webapp/controllers : python code executed by web2py when a URL is successfully mapped to a controller.

webapp/modules : python code that can be imported and used by the webpp, but is not exposed as controller

webapp/models : code that describes the database structure used by the web app

webapp/views : templates for the page content that is rendered in response to a query. The view is typically specific to a few controllers in the web app

webapp/static : static content to be returned by the web app. Contains css, images and js subdirectories for commonly used items.

webapp/private : the location to be used for storing installation-specific configuration information.

webapp/cron : directory that stores commands to be executed periodically by the web2py framework when the app is running.

webapp/databases : the location of the database files used by web2py.

webapp/languages : web2py code for internationalization

webapp/cache, webapp/databases, webapp/errors, webapp/sessions, webapp/uploads : directories used by web2py to store content associated with user's activities. Content here should not need to be committed to version control.

curator/ : similar subdirectories to those in webapp/ above
