When a setting can be read from the environment variable, avoid
accessing the internal defaults. This way the scripts can be
accessed directly in \lib as long as the environment is set up
correctly with full defaults.
The default location of osm2pgsql and the postgresql module
is decided at compile/installation time and is not necessarily
in the project directory.
With this change it is now possible to have a project directory
that is completely separate from the build directory.
Instead of creating the website wrapper scripts with cmake,
they are now created when --setup-website is called. The
setup of the configuration constants is directly embedded
into the scripts. This means we can get rid of the separate
settings-frontend.php. More importantly however, it means
that it is now possible to set up multiple website directories
from the same build directory.
DB tests now can simply set the environment to change configuration
variables. API tests still rely on a configuration file.
Also, query.php needs to set up the CONST_* variables to work with
the query scripts. That is a tiny bit messy and duplicates code
but this part will need to be reworked later.
As we can't refer to the project root dir in the module path, the
module path may now also be a relative directory which is then
taken as being relative to the project root path.
Moves the checkModulePresence() function into the Setup class, so
that it can work on the computed absolute module path.
CONST_BasePath is split into separate configuration variables
for binaries, libraries and data. These variables as well as
the installation path are now set in the executable directly and
no longer configurable via project settings.
This is the first step towards an installable software. The
executables should know per installation where to find their
necessary data to execute. Project configuration needs to be
restricted to settings that really concern the specific Nominatim
installation.
There are two places where the website URL is still used:
for icons, replace the URL with a link to the icon repository
of the UI repo. The more URL now builds the link from the
server info.
Make access to the DB object a function, so that the connection
can be opened implicitly when the object is accessed for the first
time. This way we no longer need to check beforehand if a specific
function of the setup needs DB access or not.
Also move the check for the module to the relevant sub step.
The parameter got lost when switching to website settings.
Given that the use of a fixed parameter is limited,
debugging output can now only be set via the URL parameter.
When --drop is given, we can remove all node geometry information
already after the import with osm2pgsql. Also drop all unnecessary
tables before creating the final indices.
