docs: update Windows installation documentation for Windows 7/Server 2008 R2 and newer
Update to the Windows installation documentation following my setup experience
on our production server.
Changes :
* Use of Microsoft Visual C++ Compiler for Python 2.7 which simplifies matter
versus installing Visual Studio 2008 Express, because it removes the need
to use the Visual Studio 2008 command prompt. It is also a lot smaller to
download and install. Unfortunately, this means the instruction will only
work on the same platforms as those which are supported by the compiler.
* For that reason, I split the documentation into newer and older Windows.
* Added more explanations where I feel it was necessary based on my experience
* Added explanation on Git (Warning : I did not try this part)
* Instructions assumes x64 instead of Win32.
* Clarified titles
* Grammar
Potential issues:
* I have the user install pip system wide so that virtualenv installation is
easier (especially if using Python 2.7.9 which already includes pip). One
may prefer to install virtualenv and the pip in the virtual environment (I
know of no good reason, but it could happen).
* Removed some line feeds that I found useless. I do not know the .rst
format, they might be needed. It makes no difference when the documentation
is generated using make.bat, so I am not sure
Potential improvements:
* Instructions on using srvany.exe to install as a Windows service
* Instructions to make a reverse proxy using Apache
* Instructions to make a reverse proxy using IIS

.. _installation_iis: Installing Kallithea on Microsoft Internet Information Services (IIS) ===================================================================== The following is documented using IIS 7/8 terminology. There should be nothing preventing you from applying this on IIS 6 well. .. note:: For the best security, it is strongly recommended to only host the site over a secure connection, e.g. using TLS. Prerequisites ------------- Apart from the normal requirements for Kallithea, it is also necessary to get an ISAPI-WSGI bridge module, e.g. isapi-wsgi. Installation ------------ The following will assume that your Kallithea is at ``c:\inetpub\kallithea`` and will be served from the root of its own website. The changes to serve it in its own virtual folder will be noted where appropriate. Application Pool ................ Make sure that there is a unique application pool for the Kallithea application with an identity that has read access to the Kallithea distribution. The application pool does not need to be able to run any managed code. If you are using a 32-bit Python installation, then you must enable 32 bit program in the advanced settings for the application pool otherwise Python will not be able to run on the website and consequently, Kallithea will not be able to run. .. note:: The application pool can be the same as an existing application pool as long as the requirements to Kallithea are enabled by the existing application pool. ISAPI Handler ............. The ISAPI handler can be generated using:: paster install-iis my.ini --root=/ This will generate a ``dispatch.py`` file in the current directory that contains the necessary components to finalize an installation into IIS. Once this file has been generated, it is necessary to run the following command due to the way that ISAPI-WSGI is made:: python dispatch.py install This accomplishes two things: generating an ISAPI compliant DLL file, ``_dispatch.dll``, and installing a script map handler into IIS for the ``--root`` specified above pointing to ``_dispatch.dll``. The ISAPI handler is registered to all file extensions, so it will automatically be the one handling all requests to the specified root. When the website starts the ISAPI handler, it will start a thread pool managed wrapper around the paster middleware WSGI handler that Kallithea runs within and each HTTP request to the site will be processed through this logic henceforth. Authentication with Kallithea using IIS authentication modules .............................................................. The recommended way to handle authentication with Kallithea using IIS is to let IIS handle all the authentication and just pass it to Kallithea. To move responsibility into IIS from Kallithea, we need to configure Kallithea to let external systems handle authentication and then let Kallithea create the user automatically. To do this, access the administration's authentication page and enable the ``kallithea.lib.auth_modules.auth_container`` plugin. Once it is added, enable it with the ``REMOTE_USER`` header and check *Clean username*. Finally, save the changes on this page. Switch to the administration's permissions page and disable anonymous access, otherwise Kallithea will not attempt to use the authenticated user name. By default, Kallithea will populate the list of users lazily as they log in. Either disable external auth account activation and ensure that you pre-populate the user database with an external tool, or set it to *Automatic activation of external account*. Finally, save the changes. The last necessary step is to enable the relevant authentication in IIS, e.g. Windows authentication. Troubleshooting --------------- Typically, any issues in this setup will either be entirely in IIS or entirely in Kallithea (or Kallithea's WSGI/paster middleware). Consequently, two different options for finding issues exist: IIS' failed request tracking which is great at finding issues until they exist inside Kallithea, at which point the ISAPI-WSGI wrapper above uses ``win32traceutil``, which is part of ``pywin32``. In order to dump output from WSGI using ``win32traceutil`` it is sufficient to type the following in a console window:: python -m win32traceutil and any exceptions occurring in the WSGI layer and below (i.e. in the Kallithea application itself) that are uncaught, will be printed here complete with stack traces, making it a lot easier to identify issues.
