Multipart InputStream leads to SocketException: Broken pipe / NonRepeatableRequestException

[Laurent Marchal]

Hi,

This test library is great, but i'm having some issue when trying to upload multipart streams: 

This code works :

@Test

public void testSimpleFileUpload() throws IOException {

final File indexFile = getClassPathResource("file.bin");

RestAssured.given().multiPart(indexFile).when().post("file.bin");

}

This code doesn't :

@Test

public void testMultipleStreamUpload() throws IOException {

int MB = 1024 * 1024;

byte[] buffer = new byte[16 * MB];

ByteStreams.readFully(new RandomInputStream(), buffer);

InputStream randomStream = new ByteArrayInputStream(buffer);

RestAssured.given().multiPart("file", "streamTest1", randomStream).when().post("file.bin");

}

I tried multi part upload with the okHttp and it works fine for the same URL. I can debug on the http server side, and what is weird is that the request is never made on the server for testMultipleStreamUpload(), it just fails with (error at the bottom).

Any ideas ? I also tried to find unit tests in the library so I could create a reproducible example but could not find any..

Thanks.

Sorry I don't know what could be causing this. I would suggest googling for it and if you find the reason and/or a workaround please let us know.

It seems the buffer size matters when uploading files. When trying to send less than 4Kb of data it works but then it fails if I try to upload more than that..

I'll keep looking and debugging,

[Laurent Marchal]

After some time debugging, it seems the issue comes from the server not answering properly to the HTTP specs and having buffer/streaming issues. Nothing to do with this very good library.

Thanks,

Laurent.

Thanks for sharing Laurent. Glad that you got it working.
