If you are installing from source you will need a Python 2.6+ installation and the following modules:
setuptools xlrd Sphinx
Setting up servers¶
You need to install all the database infrastructures to enable local testing.
SQLite MySQL PostgreSQL MSAccess
You will also need the following modules:
mysqldb (MySQL) psycopg2 (PostgreSQL) pyodbc (MS Access). py2app (Mac) py2exe (Windows)

The compromise on
pep8 may be a result of enforcing better code readability.
In some cases

Follow these instructions to run a complete set of tests for any branch Clone the branch you want to test.
Two ways of installing the program using the setup tools.
we can either install from source as
$ pip setup.py install
or install in development mode.
$ pip setup.py develop
you can also install from Git.
# Local repository pip install git+file:///path/to/your/git/repo # test a PIP package located in a local git repository pip install git+file:///path/to/your/git/repo@branch # checkout a specific branch by adding @branch_name at the end # Remote github repository pip install git+git://github.com/myuser/myproject # package from a github repository pip install git+git://github.com/myuser/myproject@my_branch # github repository Specific branch
Running tests locally¶
Check the services’ home pages in case you have to add the same capabilities to your master branch.
Travis AppVeyor readthedocs codecov
To run the test you will need to have all of the relevant database management systems and associated modules installed (see Setting up servers). You will then need to create the appropriate permissions for the tests to access the databases. You can do this by running the following commands in MySQL and PostgreSQL and creating the .pgpass file as described below:
MySQL ----- mysql -e "CREATE USER 'travis'@'localhost';" -uroot mysql -e "GRANT ALL PRIVILEGES ON *.* TO 'travis'@'localhost';" -uroot mysql -e "GRANT FILE ON *.* TO 'travis'@'localhost';" -uroot PostgreSQL ---------- psql -c "CREATE USER postgres WITH PASSWORD 'Password12!'" psql -c 'CREATE DATABASE testdb' psql -c 'GRANT ALL PRIVILEGES ON DATABASE testdb to postgres' Create .pgpass in your home directory: localhost:*:testdb:postgres:Password12!
To run tests we use pytest. From the source top level directory, run
To run tests on a specific test category add the path of the test module to the end of the py.test command:
$ py.test ./test/test_retriever.py
This will only run test_retriever.py
The main GitHub repository runs test on both the Travis (Linux) and AppVeyor (Windows) continuous integration platforms.
Pull requests submitted to the repository will automatically be tested using these systems and results reported in the checks section of the pull request page.
We are using Sphinx and Read the Docs. for the documentation. Sphinx uses reStructuredText as its markup language. Source Code documentation is automatically included after committing to the master. Other documentation (not source code) files are added as new reStructuredText in the docs folder
In case you want to change the organization of the Documentation, please refer to Sphinx
The documetation is automatically updated for changes with in modules. However, the documentation should be updated after addition of new modules in the engines or lib directory. Change to the docs directory and create a temporary directory, i.e. source. Run
cd docs mkdir source sphinx-apidoc -f -o ./source /Users/../retriever/
The source is the destination folder for the source rst files. /Users/../retriever/ is the path to where the retriever source code is located. Copy the .rst files that you want to update to the docs direcotry, overwriting the old files. Make sure you check the changes and edit if necessary to ensure that only what is required is updated. Commit and push the new changes. Do not commit the temporary source directory.
Test Documentation locally
cd docs # go the docs directory make html # Run Note: Do not commit the build directory after making html.
Read The Docs configuration
Configure read the docs (advanced settings) so that the source is first installed then docs are built. This is already set up but could be change if need be.
Collaborative Workflows with GitHub¶
Categorize the issues based on labels. For example (Bug, Dataset Bug, Important, Feature Request and etc..) Explain the issue explicitly with all details, giving examples and logs where applicable.
From your local branch of retriever, commit to your origin.
Once tests have passed you can then make a pull request to the retriever master (upstream)
For each commit, add the issue number at the end of the description with the tag
add version number to postgres.py to enable tracking. fixes #3
We try to make one commit for each issue. As you work on an issue, try adding all the commits into one general commit rather than several commits.
git commit --amend to add new changes to a branch.
-f flag to force pushing changes to the branch.
git push -f origin [branch_name]
