redis-compat

name	redis-compat
description	Verify moon command behavior matches Redis exactly. Args: command name(s) or --category <name>. Uses redis-cli against both servers.

Redis compatibility checker for moon commands.

Usage

• /redis-compat GETRANGE SETRANGE — check specific commands
• /redis-compat --category string — check all string commands
• /redis-compat --all — check all implemented commands

Steps

1. Start Redis server and Moon server on different ports:

   redis-server --port 6399 --daemonize yes
   cargo build --release --no-default-features --features runtime-tokio,jemalloc
   ./target/release/moon --port 6400 &
   

2. For each command, run identical operations against both servers via redis-cli:

   • Normal cases (happy path)
   • Wrong number of arguments
   • Wrong key type
   • Boundary values (empty string, very large, negative)
   • Non-existent keys

3. Compare response bytes character-for-character.

4. Use context7 to fetch latest Redis docs for edge case behavior.

5. Report per command: [COMPATIBLE|DIVERGENT|UNTESTED] with specific divergences.

6. Cleanup:

   redis-cli -p 6399 SHUTDOWN NOSAVE
   redis-cli -p 6400 SHUTDOWN NOSAVE
