!!! this is a transferred, original issue: apple/swift-nio#1270, original reporter @StrangeDays !!!

Expected behavior

• Work like developed and running on OSX
• All requests work

Actual behavior

• Fatal error: tried to decode as type Request but found Request with contents other(AsyncHTTPClient.HTTPClient.Request(method:

• Fatal error: tried to decode as type ByteBuffer but found IOData with contents other(IOData

Steps to reproduce

Run your Server on Linux via Docker (swift:latest, ...)

• Curl 7.58 bug causing chunked encoding to fail Kitura/Kitura#1465

If possible, minimal yet complete reproducer code (or URL to code)

Pretty simple RestRequest (SwiftyRequest) with responseObject and responseData

I was able to make my Code work with following steps for a workaround -- if somebody needs a quick solution

• Rewrite vom SwiftyRequest to 'classic' HTTP.request
• Use docker swift:xenial as libcurl3 is used instead of libcurl4

BTW: compiling the newest libcurl4 with swift:latest didn't work with SwiftyRequest as well

@StrangeDays hi, I'm having difficulties reproducing the crash, here is what I was trying to run:

import SwiftyRequest
import Dispatch

let request = RestRequest(method: .get, url: "http://google.com/")
let semaphore = DispatchSemaphore(value: 0)
request.responseData { result in
    switch result {
    case .success(let response):
        print(response.status)
    case .failure(let error):
        print(error)
    }
    semaphore.signal()
}
semaphore.wait()

running on:

$ uname -a
Linux swift-server-builder 4.15.0-70-generic #79-Ubuntu SMP Tue Nov 12 10:36:11 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
$ swift --version
Swift version 5.1 (swift-5.1.2-RELEASE)
Target: x86_64-unknown-linux-gnu
$ dpkg -l | grep libcurl
ii  libcurl4:amd64                             7.58.0-2ubuntu3.8                               amd64        easy-to-use client-side URL transfer library (OpenSSL flavour)

Does this issue reproduce always or intermittenly? Can you show me what your workaround was about? It strange that using libcurl3 helped, we are not relying on it at all.

[StrangeDays]

@artemredkin sry 4 responding so l8.
I need some notification strategy from regarding github ;-)

The first thing i notice is the using of DispatchSemaphore, which I don't use.
So I will check the usage of DispatchSemaphore in my code and respond asap.

[StrangeDays]

@artemredkin -- finally i got time ;-)
1st : The Bug is fixed in 1.0.1
2nd: I thing the issue is with connecting to an IP (eg. 127.0.0.1)
If you connect to an IP you should get crash with 1.0.0

[artemredkin]

@StrangeDays glad to hear that. But I would prefer to reproduce this this crash so we can add a test to prevent this from happening. Should it be the same example as earlier but with an IP address? Is it just local host or any IP? Does it have to be https? Thank you!

[weissi]

@StrangeDays / @artemredkin any updates here or can this be closed?

[artemredkin]

I was unable to reproduce the issue unfortunately

[weissi]

happy to close because @StrangeDays says it's fixed :)
