[schema] restore constraint checking when running on old sqlite
Old sqlite3 doesn't provide CHECK constraint names in error messages,
preventing us from translating a backend integrity error into a
ValidationError. This was added in 2012, but the sqlite3 version in
RHEL6 is older; so if we run on old sqlite, keep checking the
constraints in python rather than only in SQL.

Get a blog running in five minutes!
-----------------------------------
For Debian or Ubuntu users, first install the following packages
(:ref:`DebianInstallation`)::
cubicweb, cubicweb-dev, cubicweb-blog
Windows or Mac OS X users must install |cubicweb| from source (see
:ref:`SourceInstallation` and :ref:`WindowsInstallation`).
Then create and initialize your instance::
cubicweb-ctl create blog myblog
You'll be asked a few questions, and you can keep the default answer for most of
them. The one question you'll have to think about is the database you'll want to
use for that instance. For a quick test, if you don't have `postgresql` installed
and configured (see :ref:`PostgresqlConfiguration`), it's highly recommended to
choose `sqlite` when asked for which database driver to use, since it has a much
simple setup (no database server needed).
One the process is completed (including database initialisation), you can start
your instance by using: ::
cubicweb-ctl start -D myblog
The `-D` option activates the debugging mode. Removing it will launch the instance
as a daemon in the background, and ``cubicweb-ctl stop myblog`` will stop
it in that case.
About file system permissions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Unless you installed from sources, the above commands assume that you have root
access to the :file:`/etc/` directory. In order to initialize your instance as a
regular user, within your home directory, you can use the :envvar:`CW_MODE`
environment variable: ::
export CW_MODE=user
then create a :file:`~/etc/cubicweb.d` directory that will hold your instances.
More information about how to configure your own environment is
available in :ref:`ResourceMode`.
Instance parameters
~~~~~~~~~~~~~~~~~~~
If you would like to change database parameters such as the database host or the
user name used to connect to the database, edit the `sources` file located in the
:file:`/etc/cubicweb.d/myblog` directory.
Then relaunch the database creation::
cubicweb-ctl db-create myblog
Other parameters, like web server or emails parameters, can be modified in the
:file:`/etc/cubicweb.d/myblog/all-in-one.conf` file.
You'll have to restart the instance after modification in one of those files.
This is it. Your blog is functional and running. Visit http://localhost:8080 and enjoy it!
