HTTP/2 push fails with netty engine

Open elizarov opened this issue 6 years ago • 13 comments

The problem reproduces with http2-push from https://github.com/ktorio/ktor-samples

  1. Run ./gradlew :http2-push:run
  2. Navigate to https://localhost:8443/

Resulting exception:

Shame... no HTTP2 working by 2018 Tried 0.9.2, .3 and .4-alpha-2, all with Netty and Jetty Stacktrace for 0.9.4-alpha-2 with Jetty:

I found the same issue running the example on github. Somethins is off, obviously it was working before. I tried version ktor 0.9.3 with following dependencies for HTTP2 Chrome shows blank error page with: ERR_SPDY_PROTOCOL_ERROR

    compile "io.netty:netty-tcnative:2.0.14.Final"
    compile "io.netty:netty-tcnative-boringssl-static:2.0.14.Final"

ERR_SPDY_PROTOCOL_ERROR is fixed in d5e894fc127bf8829eab06a2f3f34e791d9f5a33

cy6erGn0m avatar Aug 29 '18 16:08 cy6erGn0m

Stream object required for identifier: comes from Netty internals at RST frame. It happens when Chrome rejects a push stream but Netty doesn't know this stream id yet. This may even cause reconnect. On the other hand Firefox doesn't reject but use push promise so it doesn't fail. Unfortunately there is no workaround for this for now so let it be still open.

cy6erGn0m avatar Aug 29 '18 16:08 cy6erGn0m

@cy6erGn0m it happens with Jetty too... any ideas?

guicamest avatar Aug 29 '18 16:08 guicamest

The fix works on windows. On linux the protocol is not used despite I included the right library:

    compile "io.netty:netty-tcnative:2.0.14.Final"
    compile "io.netty:netty-tcnative-boringssl-static:2.0.14.Final"
    compile "io.netty:netty-tcnative-boringssl-static:2.0.14.Final:linux-x86_64"

Still uses http 1.1. Is there anything additional to add?

In the http2 example there is also

compile "io.ktor:ktor-network-tls:$ktor_version"

is that necessary?

ghost avatar Aug 29 '18 22:08 ghost

This seems to be happening again, running ktor 1.0.0, tcnative 2.0.19.Final, Kotlin 1.3.10 I just see the message from chrome: ERR_SPDY_PROTOCOL_ERROR

The only weird trace I see is:

2018-11-16 00:55:09.259|nettyWorkerPool-3-5|Slf4JLogger.java:146:warn() - [WARN] i.n.h.s.ApplicationProtocolNegotiationHandler: [id: 0x48cf2925, L:/0:0:0:0:0:0:0:1:8103 R:/0:0:0:0:0:0:0:1:49904] TLS handshake failed:
javax.net.ssl.SSLException: handshake timed out
        at io.netty.handler.ssl.SslHandler.handshake(...)(Unknown Source)

Couldn't it be a timeout issue? This was not happening in 0.9.4 Now this happens again on windows too.

ghost avatar Nov 16 '18 00:11 ghost

wow, every new micro service I write I forget this ticket is already open :P Need that HTTP/2 working. I did run with ktor 1.1.1, kotlin 1.3.11. Getting ERR_SPDY_PROTOCOL_ERROR on the https port.

Certificate is fine, nothing is logged by ktor when request is sent. Security tab is fine

ghost avatar Jan 05 '19 17:01 ghost

Having ERR_SPDY_PROTOCOL_ERROR with ktor 1.1.3 and as well 1.2.0-alpha-1.3.0-eap-125. Kotlin version: 1.3.21

If I use curl it seems to work fine (because only one call and connection). But in Chrome I get the error. In Safari it doesn't work either. (In browser opening a website with static files)

Happens to me with netty and jetty.

pboos avatar Apr 03 '19 13:04 pboos

Looks like either:

  • We (a.k.a) users don't know how to use it. We have to read the Instructions again...
  • The maintainers don't care about this. Too bad for Kotlin's flagship web-server. Either way, they could at least reply.

guicamest avatar Apr 20 '19 12:04 guicamest

Still getting this, could it be we didn't understand the documentation?

Activating the logging in Chrome I see this:

t=275253 [st=3] HTTP2_STREAM_ERROR --> description = "Server reset stream." --> net_error = "ERR_SPDY_PROTOCOL_ERROR" --> stream_id = 71 t=275253 [st=3] -HTTP_TRANSACTION_READ_HEADERS --> net_error = -337 (ERR_SPDY_PROTOCOL_ERROR) t=275253 [st=3] -URL_REQUEST_START_JOB --> net_error = -337 (ERR_SPDY_PROTOCOL_ERROR)
