db: introduce migration step after 93834966ae01 dropped non-nullable inherit_default_permissions
The database migration step was lazily and naively skipped ... but that turns
out to be a problem when new users are added.
In the database, the original column 'inherit_default_permissions' was
marked as non-nullable without default value. In the Kallithea code after
commit 93834966ae01, the column 'inherit_default_permissions' was no longer
known, and thus not given a value when new users are added. As a result, the
database complained:
IntegrityError: (psycopg2.errors.NotNullViolation) null value in column "inherit_default_permissions" violates not-null constraint
Fix that now by adding an appropriate db migration step to actually remove
the columns.
Use meta reflection to check if columns exist before running the upgrade
step. The upgrade step only has to be run if it is an old database - not if
it has been created after the schema changes were introduced.
For the downgrade step, make sure to set a default value for non-nullable
columns.

.. _vcs_setup: ============================= Version control systems setup ============================= Kallithea supports Git and Mercurial repositories out-of-the-box. For Git, you do need the ``git`` command line client installed on the server. You can always disable Git or Mercurial support by editing the file ``kallithea/__init__.py`` and commenting out the backend. For example, to disable Git but keep Mercurial enabled: .. code-block:: python BACKENDS = { 'hg': 'Mercurial repository', #'git': 'Git repository', } Git-specific setup ------------------ Web server with chunked encoding ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Large Git pushes require an HTTP server with support for chunked encoding for POST. The Python web servers waitress_ and gunicorn_ (Linux only) can be used. By default, Kallithea uses waitress_ for `gearbox serve` instead of the built-in `paste` WSGI server. The web server used by gearbox is controlled in the .ini file:: use = egg:waitress#main or:: use = egg:gunicorn#main Also make sure to comment out the following options:: threadpool_workers = threadpool_max_requests = use_threadpool = Increasing Git HTTP POST buffer size ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If Git pushes fail with HTTP error code 411 (Length Required), you may need to increase the Git HTTP POST buffer. Run the following command as the user that runs Kallithea to set a global Git variable to this effect:: git config --global http.postBuffer 524288000 .. _waitress: http://pypi.python.org/pypi/waitress .. _gunicorn: http://pypi.python.org/pypi/gunicorn .. _subrepositories: http://mercurial.aragost.com/kick-start/en/subrepositories/
