README

A server to support /hash, /hash/{id}, /stats, /shutdown endpoints, implemented in Go.

How to run

Clone the repository and run:

go run main.go

How to test

First, run the server from terminal using above command. Curl, ab can be used to make calls to the server as follow:

/hash call (Must be POST)

curl -X POST localhost:8080/hash -d password="myPassword"

or, create a postdata file with content: password=abcdefg, then run:

ab -n 100 -c 10 -v 4 -T application/x-www-form-urlencoded -p ./postdata http://localhost:8080/hash

/hash/{id} call

curl localhost:8080/hash/1

/stats call (Must be GET)

curl -X GET localhost:8080/stats

/shutdown call

curl localhost:8080/shutdown

Instructions

• Uses Channel to support concurrent requests.
• /hash endpoint waits for 5 seconds before processing the request.
• A buffered channel of capacity is 200 is used for proccessing incoming requests. This can be changed using 'ChannelCapacity' config.
• /stats endpoint returns the total number of requests and average time in microseconds required to process each request.
• /shutdown endpoint does a graceful shutdown, waits for 'PreprocessingDelay' for any pending requests.
• By default, the server runs on port 8080. This can be changed using DefaultPort config.

Cheers!
