1 # Setting up Nominatim for Development
3 This chapter gives an overview how to set up Nominatim for developement
7 This guide assumes that you develop under the latest version of Ubuntu. You
8 can of course also use your favourite distribution. You just might have to
9 adapt the commands below slightly, in particular the commands for installing
12 ## Installing Nominatim
14 The first step is to install Nominatim itself. Please follow the installation
15 instructions in the [Admin section](../admin/Installation.md). You don't need
16 to set up a webserver for development, the webserver that is included with PHP
19 If you want to run Nominatim in a VM via Vagrant, use the default `ubuntu` setup.
20 Vagrant's libvirt provider runs out-of-the-box under Ubuntu. You also need to
21 install an NFS daemon to enable directory sharing between host and guest. The
22 following packages should get you started:
24 sudo apt install vagrant vagrant-libvirt libvirt-daemon nfs-kernel-server
26 ## Prerequisites for testing and documentation
28 The Nominatim test suite consists of behavioural tests (using behave) and
29 unit tests (using PHPUnit). It has the following additional requirements:
31 * [behave test framework](https://behave.readthedocs.io) >= 1.2.5
32 * [nose](https://nose.readthedocs.io)
33 * [phpunit](https://phpunit.de) >= 7.3
34 * [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer)
36 The documentation is built with mkdocs:
38 * [mkdocs](https://www.mkdocs.org/) >= 1.1.2
40 ### Installing prerequisites on Ubuntu/Debian
42 Some of the Python packages require the newest version which is not yet
43 available with the current distributions. Therefore it is recommended to
44 install pip to get the newest versions.
46 To install all necessary packages run:
49 sudo apt install php-cgi phpunit php-codesniffer \
50 python3-pip python3-setuptools python3-dev
52 pip3 install --user behave nose mkdocs
55 The `mkdocs` executable will be located in `.local/bin`. You may have to add
56 this directory to your path, for example by running:
59 echo 'export PATH=~/.local/bin:$PATH' > ~/.profile
62 If your distribution does not have PHPUnit 7.3+, you can install it (as well
63 as CodeSniffer) via composer:
66 sudo apt-get install composer
67 composer global require "squizlabs/php_codesniffer=*"
68 composer global require "phpunit/phpunit=8.*"
71 The binaries are found in `.config/composer/vendor/bin`. You need to add this
75 echo 'export PATH=~/.config/composer/vendor/bin:$PATH' > ~/.profile
81 All tests are located in the `\test` directory.
83 ### Preparing the test database
85 Some of the behavioural test expect a test database to be present. You need at
86 least 2GB RAM and 10GB disk space to create the database.
88 First create a separate directory for the test DB and fetch the test planet
89 data and the Tiger data for South Dakota:
94 wget https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
95 wget -O - https://nominatim.org/data/tiger2018-nominatim-preprocessed.tar.gz | tar xz --wildcards --no-anchored '46*'
98 Configure and build Nominatim in the usual way:
101 cmake $USERNAME/Nominatim
105 Create a minimal test settings file:
109 NOMINATIM_DATABASE_DSN="pgsql:dbname=test_api_nominatim"
110 NOMINATIM_USE_US_TIGER_DATA=yes
111 NOMINATIM_TIGER_DATA_PATH=tiger
112 NOMINATIM_WIKIPEDIA_DATA_PATH=$USERNAME/Nominatim/test/testdb
116 Inspect the file to check that all settings are correct for your local setup.
117 In particular, the wikipedia path should point to the test directory in your
118 Nominatim source directory.
120 Now you can import the test database:
123 dropdb --if-exists test_api_nominatim
124 ./utils/setup.php --all --osm-file nominatim-api-testdb.pbf 2>&1 | tee import.log
125 ./utils/specialphrases.php --wiki-import | psql -d test_api_nominatim 2>&1 | tee -a import.log
126 ./utils/setup.php --import-tiger-data 2>&1 | tee -a import.log
129 ### Running the tests
131 To run all tests just go to the test directory and run make:
138 To skip tests that require the test database, run `make no-test-db` instead.
140 For more information about the structure of the tests and how to change and
141 extend the test suite, see the [Testing chapter](Testing.md).
143 ## Documentation Pages
145 The [Nominatim documentation](https://nominatim.org/release-docs/develop/) is
146 built using the [MkDocs](https://www.mkdocs.org/) static site generation
147 framework. The master branch is automatically deployed every night on
148 [https://nominatim.org/release-docs/develop/](https://nominatim.org/release-docs/develop/)
150 To build the documentation, go to the build directory and run
154 INFO - Cleaning site directory
155 INFO - Building documentation to directory: /home/vagrant/build/site-html
158 This runs `mkdocs build` plus extra transformation of some files and adds
159 symlinks (see `CMakeLists.txt` for the exact steps).
161 Now you can start webserver for local testing
165 [server:296] Serving on http://127.0.0.1:8000
166 [handlers:62] Start watching changes
169 If you develop inside a Vagrant virtual machine, use a port that is forwarded
173 build> mkdocs serve --dev-addr 0.0.0.0:8088
174 [server:296] Serving on http://0.0.0.0:8088
