Honestly, a spreadsheet with extra steps.
The purpose of this project is to provide a simple way to record the amount of hours you spend at work. This is useful if you are working a lot of unregistered overtime. The API provides endpoints for starting and stopping a work session, computing the total amount of overtime and checking if you are currently working overtime.
The program is written in C using UNIX sockets. The main loop listens for incomming TCP requests and parses the requests manually. If a valid HTTP message is detected, the request is routed to a matching function. If there is no match for the path, a 404 response is dispatched. If there is a match, an action will be performed and a proper response is written back on the TCP socket.
SQLite is used for persistence. The most important table is the time table, which holds a "from" date and a "to" date stored as epoch timestamps in seconds. Every entry in the time table corresponds to a work session.
There are two ways to run the program, direct or Docker.
- gcc/clang
- sqlite headers
You need to build the logging library first:
cd clogger && make && cd ..
Then you can build the application:
make
./server
Build the Docker image:
docker build --rm -t worktrack:latest .
The --rm flag cleans up intermediate images, and the -t flag tags the image.
Run a container from the image:
docker run -p 8080:8080 -d --rm --name worktrack worktrack:latest
This will expose the container port 8080 on the host port 8080. The -d flag runs the container in the background and the --rm flag cleans up the container after it exits. The --name flag names the container (we use this to easily check the logs without copying the container ID).
To observe the application:
docker logs worktrack
bash -x run_e2e_tests.sh
The -x make bash print each line before it is executed, giving you
some idea of what is happening.
I wanted to learn how to make a HTTP web server in C.
