PHP 5.5
PHP extensions: ctype, json, pdo (with respective drivers), session, simplexml, xmlwriter, xdebug (only for tests)
MySQL, PostgreSQL or SQLite (over PDO driver)
browser with javascript enabled, cookies for authentication and saving preferences

Features:

simple
allows live tracking
track statistics
altitudes graph
multiple users
user authentication
Google Maps
OpenLayers (OpenStreet and other layers)
user preferences stored in cookies
simple admin menu
export tracks to gpx and kml
import tracks from gpx

Install

Download zipped archive or clone the repository on your computer
Move it to your web server directory (unzip if needed)
Fix folder permissions: uploads folder (for uploaded images) should be writeable by PHP scripts
In case of development version it is necessary to build javascript bundle from source files. You will need to install npm and run npm install and npm run build in root folder
Create database and database user (at least SELECT, INSERT, UPDATE, DELETE privileges, CREATE, DROP for setup script, SEQUENCES for postgreSQL)
Create a copy of config.default.php and rename it to config.php. Customize it and add database credentials
Edit scripts/setup.php script, enable it by setting $enabled value to true
Make sure you have a web server running with PHP and chosen database
Open http://YOUR_HOST/ulogger-server/scripts/setup.php page in your browser
Follow instructions in setup script. It will add database tables and set up your μlogger user
Remember to remove or disable scripts/setup.php script
Log in with your new user on http://YOUR_HOST/ulogger-server/
You may also want to set your new user as an admin in config file
Folders .docker/ and .tests/ as well as composer files are needed only for development. May be safely removed

Upgrade to version 1.x

Incompatible changes include database and config file changes
Upgrading manually:
for database changes, see MySQL example script in scripts/migrate_to_1_x.mysql
set admin column in users table to true for admin users
edit configuration from application settings dialog
Upgrading with migration script from version 0.6:
create database backup
replace all project files with new ones, but keep old local config file: config.php
change directory to application root folder and run migration script from the console: php scripts/migrate_to_1_x.php
the script will update database schema and save old config variables to database
Additional tasks after manual or script update:
edit your config.php file and remove all variables except database settings, see config.default.php for valid values
make sure uploads folder (for images uploaded from client app) is writable by PHP
clear browser cache and restart web page

Docker

Run docker run --name ulogger -p 8080:80 -d bfabiszewski/ulogger and access http://localhost:8080 in your browser. Log in with admin:admin credentials and change default password
Optional configuration options with ENV variables, for list see Dockerfile. The variables correspond to main μlogger configuration parameteres
For example: docker run --name ulogger -e ULOGGER_LANG="pl" -p 8080:80 -d bfabiszewski/ulogger
You may also build the image yourself. Run docker build . from the root folder where Dockerfile reside. There are optional build-time arguments that allow you to set default database passwords for root and ulogger users
For example: docker build --build-arg DB_ROOT_PASS=secret1 --build-arg DB_USER_PASS=secret2 --build-arg DB_DRIVER=sqlite .
Docker was created to facilitate development and testing. It is not production ready. If you want to use it in production, you will have to adjust it to your needs.

Tests

Install tests dependecies. PHP tests require PHP >= 7.3.
composer install
npm install
Integration tests may be run against docker image. We need exposed http and optionally database ports (eg. mapped to localhost 8080 and 8081). Below example for MySQL setup
docker build -t ulogger .
docker run -d --name ulogger -p 8080:80 -p 8081:3306 --expose 3306 -e ULOGGER_ENABLE_SETUP=1 ulogger
Use environment variables (or create .env file in .tests/ folder) to set up connection details (below database credentials are docker defaults)
DB_DSN="mysql:host=127.0.0.1;port=8081;dbname=ulogger;charset=utf8"
DB_USER=ulogger
DB_PASS=secret2
ULOGGER_URL="http://127.0.0.1:8080"
PHP tests
XDEBUG_MODE=coverage ./vendor/bin/phpunit -c .tests/phpunit.xml
JS tests
npm test
Other tests
