aioftp¶
ftp client/server for asyncio.
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.
aioftp 0.8.0
STOR (client -> server) 284.95 MB/sec
RETR (server -> client) 408.44 MB/sec
200 concurrent clients (connect, login) 0.18 secs
STOR (1 file with 200 idle clients) 287.52 MB/sec
RETR (1 file with 200 idle clients) 382.05 MB/sec
200 concurrent clients (RETR 10.0M file) 13.33 secs
200 concurrent clients (STOR 10.0M file) 12.56 secs
200 concurrent clients (QUIT) 0.03 secs
pyftpdlib 1.5.2
STOR (client -> server) 1235.56 MB/sec
RETR (server -> client) 3960.21 MB/sec
200 concurrent clients (connect, login) 0.06 secs
STOR (1 file with 200 idle clients) 1208.58 MB/sec
RETR (1 file with 200 idle clients) 3496.03 MB/sec
200 concurrent clients (RETR 10.0M file) 0.55 secs
200 concurrent clients (STOR 10.0M file) 1.46 secs
200 concurrent clients (QUIT) 0.02 secs

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).
import asyncio
import aioftp
async def get_mp3(host, port, login, password):
async with aioftp.Client.context(host, port, login, password) as client:
for path, info in (await client.list(recursive=True)):
if info["type"] == "file" and path.suffix == ".mp3":
await client.download(path)
async def main():
tasks = [
asyncio.create_task(get_mp3("server1.com", 21, "login", "password")),
asyncio.create_task(get_mp3("server2.com", 21, "login", "password")),
asyncio.create_task(get_mp3("server3.com", 21, "login", "password")),
]
await asyncio.wait(tasks)
asyncio.run(main())
Server example
import asyncio
import aioftp
async def main():
server = aioftp.Server([user], path_io_factory=path_io_factory)
await server.run()
asyncio.run(main())
Or just use simple server
python -m aioftp --help
