db: introduce constraint ensuring no duplicate (reviewer, pullrequest) combinations
A reviewer should only be added once to a review.
Previously, this was not ensured by the database itself, although that the
controller would try to not add duplicate reviewers. But there was no hard
guarantee: e.g. simultaneous adding of the same reviewer to the same review
by a review owner and admin, a framework bug that sends the same request
twice, ... could still trigger duplicate addition. Additionally, code
changes (e.g. a new API) could introduce bugs at the controller level.
Existing production databases were found to contain such duplicate entries.
Nevertheless, as the code displaying reviewers in a pull request filtered
out duplicates, this never showed in the UI, and never was a 'real' problem.
Add a UniqueConstraint in the database to prevent such entries, with a
database migration step that will first find and remove existing duplicates.

Troubleshooting
===============
:Q: **Missing static files?**
:A: Make sure either to set the ``static_files = true`` in the .ini file or
double check the root path for your http setup. It should point to
for example:
``/home/my-virtual-python/lib/python3.7/site-packages/kallithea/public``
|
:Q: **Can't install celery/rabbitmq?**
:A: Don't worry. Kallithea works without them, too. No extra setup is required.
Try out the great Celery docs for further help.
|
:Q: **Long lasting push timeouts?**
:A: Make sure you set a longer timeout in your proxy/fcgi settings. Timeouts
are caused by the http server and not Kallithea.
|
:Q: **Large pushes timeouts?**
:A: Make sure you set a proper ``max_body_size`` for the http server. Very often
Apache, Nginx, or other http servers kill the connection due to to large
body.
|
:Q: **Apache doesn't pass basicAuth on pull/push?**
:A: Make sure you added ``WSGIPassAuthorization true``.
|
:Q: **Git fails on push/pull?**
:A: Make sure you're using a WSGI http server that can handle chunked encoding
such as ``waitress`` or ``gunicorn``.
|
:Q: **How can I use hooks in Kallithea?**
:A: It's easy if they are Python hooks: just use advanced link in
hooks section in Admin panel, that works only for Mercurial. If
you want to use Git hooks, just install th proper one in the repository,
e.g., create a file `/gitrepo/hooks/pre-receive`. You can also use
Kallithea-extensions to connect to callback hooks, for both Git
and Mercurial.
|
:Q: **Kallithea is slow for me, how can I make it faster?**
:A: See the :ref:`performance` section.
|
:Q: **UnicodeDecodeError on Apache mod_wsgi**
:A: Please read: https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/modwsgi/#if-you-get-a-unicodeencodeerror.
|
:Q: **Requests hanging on Windows**
:A: Please try out with disabled Antivirus software, there are some known problems with Eset Antivirus. Make sure
you have installed the latest Windows patches (especially KB2789397).
