I'm trying to build ktor from scratch (I'm interested in native curl, I need to customize the libcurl client) but tests are failing, is this known?

[ RUN      ] io.ktor.client.test.CurlEnginesTest.postTest
kotlin.AssertionError: Expected <HttpBinResponse(url=<http://httpbin.org/post>, args={}, headers={Content-Type=text/plain; charset=UTF-8, Accept=application/json, Content-Length=11, Connection=close, Host=<http://httpbin.org|httpbin.org>})>, actual <HttpBinResponse(url=<http://httpbin.org/post>, args={}, headers={Accept=application/json, Connection=close, Content-Length=11, Content-Type=text/plain; charset=UTF-8, Host=<http://httpbin.org|httpbin.org>, X-Imforwards=20})>.

Hi @jdiaz, the CURL engine is available in ktor 1.1.2

[e5l]

Probably it’s the curl version issue, could you provide the OS and CURL versions to figure it out?

[jdiaz]

@e5l curl 7.43.0 (x86_64-apple-darwin15.0.0) libcurl/7.43.0 SecureTransport zlib/1.2.5

[jdiaz]

I know curl engine is available, I made it work but there's not enough customization as I need to provide some other parameters to libcurl

[e5l]

We test it with 7.63

[jdiaz]

Same thing with: curl 7.63.0 (x86_64-apple-darwin15.6.0) libcurl/7.63.0 SecureTransport zlib/1.2.5 libidn2/2.0.5

[jdiaz]

➜  ktor git:(master) where curl
/usr/local/opt/curl/bin/curl

[e5l]

Anyway, it looks like the HttpBin provides the additional header and this test should be changed.

[e5l]

What do you want to customize in Curl? Probably we should introduce the extension point in configuration.

[jdiaz]

This would be more or less what I'd need

curl_easy_setopt(curl, CURLOPT_COOKIEFILE, file)
curl_easy_setopt(curl, CURLOPT_UNRESTRICTED_AUTH, 1L)
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L)
curl_easy_setopt(curl, CURLOPT_HTTPAUTH, auth)
curl_easy_setopt(curl, CURLOPT_USERPWD, user)

[jdiaz]

Maybe a function that you can handle in a low level way the curl object and some extension functions to make that easier
