http4s-stream-paged
This is a small demo project demonstrating the problems I encountered while trying to migrate a consumer for a multipart HTTP resource to http4s 1.0.0.
Try it
Start the server
cd 0.22/
sbt "runMain com.l7r7.lab.http4s.multipart.server.Server"
This will start up a web server for testing.
Then run the client using http4s v0.21.22:
cd 0.22/
sbt "runMain com.l7r7.lab.http4s.multipart.ClientApp"
This will get the page, and print out the different parts. The multipart parsing works.
However, if you run the client using http4s v1.0.0-M21:
cd 1.0/
sbt "runMain com.l7r7.lab.http4s.multipart.ClientApp"
The program will fail with the following error:
(run-main-0) org.http4s.MalformedMessageBodyFailure: Malformed message body: Malformed Malformed match
org.http4s.MalformedMessageBodyFailure: Malformed message body: Malformed Malformed match

The client code is the same (except from the new Header handling), so I'm not sure if I found a bug or if I should do it differently somehow
