aioftp
ftp client/server for asyncio (https://aioftp.rtfd.io)
Features
Simple.
Extensible.
Client socks proxy via siosocks (pip install aioftp[socks]).
Goals
Minimum usable core.
Do not use deprecated or overridden commands and features (if possible).
Very high level api.
Client use this commands: USER, PASS, ACCT, PWD, CWD, CDUP, MKD, RMD, MLSD, MLST, RNFR, RNTO, DELE, STOR, APPE, RETR, TYPE, PASV, ABOR, QUIT, REST, LIST (as fallback)
Server support this commands: USER, PASS, QUIT, PWD, CWD, CDUP, MKD, RMD, MLSD, LIST (but it’s not recommended to use it, cause it has no standard format), MLST, RNFR, RNTO, DELE, STOR, RETR, TYPE (“I” and “A”), PASV, ABOR, APPE, REST
This subsets are enough for 99% of tasks, but if you need something, then you can easily extend current set of commands.
Server benchmark
Compared with pyftpdlib and checked with its ftpbench script.

Getting started
Client example
WARNING
For all commands, which use some sort of «stats» or «listing», aioftp tries at first MLSx-family commands (since they have structured, machine readable format for all platforms). But old/lazy/nasty servers do not implement this commands. In this case aioftp tries a LIST command, which have no standard format and can not be parsed in all cases. Take a look at FileZilla «directory listing» parser code. So, before creating new issue be sure this is not your case (you can check it with logs). Anyway, you can provide your own LIST parser routine (see the client documentation).
