# Lander
|
|
|
|
Lander is an HTTP/1.1 server that acts as a URL shortener, pastebin and
|
|
file-sharing service. It's written from the ground up in C, complete with an
|
|
HTTP framework built on top of an event loop implementation based on [Build
|
|
Your Own Redis with C/C++](https://build-your-own.org/redis/). Lookup of
|
|
entries is done using an in-memory trie data structure, and on-disk storage
|
|
uses a custom binary database format.
|
|
|
|
The codebase uses one thirdparty library, namely
|
|
[picohttpparser](https://github.com/h2o/picohttpparser) for parsing HTTP
|
|
requests.
|
|
|
|
## The idea
|
|
|
|
A URL shortener has always been on my list of things I'd like to write myself.
|
|
It's simple, yet useful.
|
|
|
|
for our Algorithms & Datastructures 3 class, we had to implement three
|
|
different tries (Patricia trie, ternary trie, and a custom one). Considering
|
|
these are efficient string-based search trees, this gave me the idea to use it
|
|
as the backend for a URL shortener!
|
|
|
|
## The name
|
|
|
|
I gave up giving my projects original names a long time ago, so now I just use
|
|
the names of my friends ;p
|
|
|
|
## Benchmarking
|
|
|
|
I benchmark this tool using the [`wrk2`](https://github.com/giltene/wrk2)
|
|
utility. I've provided two Lua scripts to aid with this. To bench publishing
|
|
redirects, use the following:
|
|
|
|
```sh
|
|
wrk2 -s bench/post.lua -t 10 -R 10k -d30s -c32 http://localhost:18080
|
|
```
|
|
|
|
And to bench GET requests:
|
|
|
|
```sh
|
|
wrk2 -s bench/get.lua -t 10 -R 25k -d30s -c32 http://localhost:18080
|
|
```
|
|
|
|
Of course you're free to change the parameters, but the provided Lua files
|
|
generate URLs that can be used in the benchmark.
