Only receiving first chunk of data using FileMiddleware server

[GP89]

Describe the bug

Only receiving first chunk of data receiving from FileMiddleware static server.

This could well be due to the way I'm using Network.framework as a test client, but I'm really not sure where the problem lies.

To Reproduce

I created a test project that demonstates the behaviour: TestStaticServer

Steps to reproduce the behavior:

1. Run TestStaticServer target
2. Run Downloader target
3. Client only receives (for me) first chunk of data (174bytes) then no more

Expected behavior

Receive should keep receiving data until the whole file is sent (~3kb)

Environment

• Vapor Framework version: main branch
• Vapor Toolbox version: ?
• OS version: 12.3.1

Hey so I make a stupid mistake in that example! I was using strlen to get the message size, which is only the size until the first null byte 🤦 . So can confirm all the data is being received.
However the client is still sitting on receive expecting more data as is_complete doesn't come back as true. I'm not sure where / what the problem could be there

According to the Network.framework docs, if you're doing raw, unbounded TCP, is_complete will only be true if the other side closes the connection. In HTTP 1.1, connections are persistent by default, meaning that the server will not close the connection at the end of the response.

You could change the request line to say HTTP/1.0, or add a Connection: close header to the request, and it should be closed automatically by the server. (Or you could just use a real HTTP client instead?)

Ah thank you!! Sorry I'll close this off.

I needed something that used tls psk and plain tcp was the only way I could find in objective-c.

Hey I've just tried with HTTP/1.0 and with Connection: close but I'm still seeing the same behaviour. Gets all the data and sits on state 3 (ready) waiting to receive again

Do you get the same behaviour when serving the file from something like Nginx?
