This is a starting point for Python solutions to the
["Build Your Own Redis" Challenge](https://codecrafters.io/challenges/redis).
In this challenge, you'll build a toy Redis clone that's capable of handling
basic commands like `PING`, `SET` and `GET`. Along the way we'll learn about
event loops, the Redis protocol and more.
**Note**: If you're viewing this repo on GitHub, head over to
[codecrafters.io](https://codecrafters.io) to try the challenge.
# Passing the first stage
The entry point for your Redis implementation is in `app/main.py`. Study and
uncomment the relevant code, and push your changes to pass the first stage:
```sh
git commit -am "pass 1st stage" # any msg
git push origin master
```
That's all!
# Stage 2 & beyond
Note: This section is for stages 2 and beyond.
1. Ensure you have `python (3.x)` installed locally
1. Run `./your_program.sh` to run your Redis server, which is implemented in
`app/main.py`.
1. Commit your changes and run `git push origin master` to submit your solution
to CodeCrafters. Test output will be streamed to your terminal.
# Troubleshooting
## module `socket` has no attribute `create_server`
When running your server locally, you might see an error like this:
```
Traceback (most recent call last):
File "/.../python3.7/runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)
File "/.../python3.7/runpy.py", line 85, in _run_code
exec(code, run_globals)
File "/app/app/main.py", line 11, in
main()
File "/app/app/main.py", line 6, in main
s = socket.create_server(("localhost", 6379), reuse_port=True)
AttributeError: module 'socket' has no attribute 'create_server'
```
This is because `socket.create_server` was introduced in Python 3.8, and you
might be running an older version.
You can fix this by installing Python 3.8 locally and using that.
If you'd like to use a different version of Python, change the `language_pack`
value in `codecrafters.yml`.
