io.UnsupportedOperation: seek

Hi,

I really like this service a lot.

During a deployment I received the following error message when uploading remote files via the "url" field:

io.UnsupportedOperation: seek

I can kind of reproduce the issue, since the file stream there is not "seekable":

import requests

def urlfile(**kwargs):
        return type('',(),kwargs)()

r = requests.get('https://i.imgflip.com/1igc7m.jpg', stream=True, verify=False, headers={ "Accept-Encoding" : "identity" })

f = urlfile(stream=r.raw, content_type=r.headers["content-type"], filename="")

data = f.stream.read()
f.stream.seek(0)

>>> f.stream.seekable()
False

>>> f.stream.seek(0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
io.UnsupportedOperation: seek

The issue is mainly appearing when trying to save remote urls with the "url" parameter like so:

curl -F'url=https://i.imgflip.com/1igc7m.jpg' https://0x0.example.com

The issue does not appear on the reference instance https://0x0.st, so it's probably just me :) Would appreciate any hint or feedback on how to make it work with the saving of remote urls.

Many thanks.

Sorry about the late response. Could you tell me more about your server configuration? Like the app server running your instance, and what’s facing the client (e.g. nginx). Include config file snippets.

Thanks for getting back to me.

I was using Nomad with Nginx at that time. All the code and configuration is stored here:

It worked really well for me. Was running the deployment on Raspberry Pie. That might be relevant.

Thanks and have a good day

Hm. There are definitely some issues with 0x0’s code in the affected function. No idea why seeking that stream is even working for me! Something must be implicitly buffering the response, but only in some environments (gunicorn apparently is not one of those).

Anyway, this should be an easy thing to fix.
