ftp client/server for asyncio
Project description
ftp client/server for asyncio (http://pohmelie.github.io/aioftp or http://aioftp.readthedocs.org (no python 3.5))
Features
Simple.
Extensible.
Proxy via twunnel3.
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
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 (only “I”), PASV, ABOR, APPE
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 it’s ftpbench script.
aioftp 0.4.1
$ ./ftpbench -u anonymous -p none -P 8021 -b all STOR (client -> server) 146.06 MB/sec RETR (server -> client) 273.88 MB/sec 200 concurrent clients (connect, login) 0.36 secs STOR (1 file with 200 idle clients) 121.02 MB/sec RETR (1 file with 200 idle clients) 274.31 MB/sec 200 concurrent clients (RETR 10.0M file) 16.09 secs 200 concurrent clients (STOR 10.0M file) 19.03 secs 200 concurrent clients (QUIT) 0.11 secs
pyftpdlib 1.5.0
$ ./ftpbench -u anonymous -p none -P 8021 -b all STOR (client -> server) 198.65 MB/sec RETR (server -> client) 3361.68 MB/sec 200 concurrent clients (connect, login) 0.09 secs STOR (1 file with 200 idle clients) 209.34 MB/sec RETR (1 file with 200 idle clients) 3367.59 MB/sec 200 concurrent clients (RETR 10.0M file) 1.04 secs 200 concurrent clients (STOR 10.0M file) 1.98 secs 200 concurrent clients (QUIT) 0.02 secs

Library Installation
pip install aioftp
Getting started
Client example
import asyncio
import aioftp
async def get_mp3(host, login, password):
client = aioftp.Client()
await client.connect(host)
await client.login(login, password)
async for path, info in await client.list(recursive=True):
if info["type"] == "file" and path.suffix == ".mp3":
await client.download(path)
await client.quit()
loop = asyncio.get_event_loop()
tasks = (
get_mp3("server1.com", "login", "password")),
get_mp3("server2.com", "login", "password")),
get_mp3("server3.com", "login", "password")),
)
loop.run_until_complete(asyncio.wait(tasks))
loop.close()Server example
import asyncio
import aioftp
loop = asyncio.get_event_loop()
server = aioftp.Server()
loop.run_until_complete(server.start(None, 8021))
try:
loop.run_forever()
except KeyboardInterrupt:
server.close()
loop.run_until_complete(server.wait_closed())
loop.close()Or just use simple server
