What did you do?

So, let's begin

High-Level Problem Description
I'm creating reverse proxy with Caddy Server and my own plugin. I use http/2 and Server Push. Sometimes requests hang forever. Here is screenshot from Chrome DevTools:

Low-Level Problem Description
So, I started to debug this situation. I found that my code execution stuck at (http.responseWriter).Write(), which is an instance of http2responseWriter.
With help of pprof I found that lockup happens in two functions: http2serverConn.writeHeaders and http2serverConn.writeDataFromHandler - endless waiting of data from done channel.
Here is an illustration from pprof:
out02

Next I built go from source with adding some debug messages and start to dive deeper.
I found a problem with frames are sent to output. At this line N frames were pushed: https://github.com/golang/go/blob/go1.15.4/src/net/http/h2_bundle.go#L4692. After push-function scheduleFrameWrite-function is called. I watched into it and found that it often exit here: https://github.com/golang/go/blob/go1.15.4/src/net/http/h2_bundle.go#L4817. And only M (M < N) frames were popped from queue here: https://github.com/golang/go/blob/go1.15.4/src/net/http/h2_bundle.go#L4837

@dtelyukh We are going to need something that can reproduce the issue. It would also help to enable http2 debug and a thread dump when it hangs.

Your title says the bundled version of http2 has this issue. Are you implying that if you use the latest x/net/http2 you dont?

@dtelyukh We are going to need something that can reproduce the issue. It would also help to enable http2 debug and a thread dump when it hangs.

It's not easy to prepare code, which can reproduce this problem with 100% guarantee, but I think I could try.
Here is debug.log for GODEBUG=http2debug=2
http2.debug.log
and goroutines dump with pprof
goroutine.dump.log

Your title says the bundled version of http2 has this issue. Are you implying that if you use the latest x/net/http2 you dont?

h2_bundle.go used by third-party code. I didn't try to use x/net/http2 directly. Do you mean that I should do that?

Don't worry. I am going to need something that can reproduce this issue.
I can see why nothing is making progress but I don't know why.
The debug log is incomplete or slightly broken, but from what I do see there is an oddity.

2020/11/13 10:44:00 http2: Framer 0xc000af61c0: read HEADERS flags=END_STREAM|END_HEADERS|PRIORITY stream=1511 len=21
2020/11/13 10:44:00 http2: Framer 0xc000af61c0: wrote PUSH_PROMISE flags=END_HEADERS stream=1511 len=293
2020/11/13 10:44:00 http2: Framer 0xc000af61c0: read PRIORITY stream=314 len=5
2020/11/13 10:44:00 http2: Framer 0xc000af61c0: wrote PUSH_PROMISE flags=END_HEADERS stream=1511 len=33
2020/11/13 10:44:00 http2: Framer 0xc000af61c0: wrote HEADERS flags=END_HEADERS stream=314 len=120
2020/11/13 10:44:00 http2: Framer 0xc000af61c0: wrote PUSH_PROMISE flags=END_HEADERS stream=1511 len=44
2020/11/13 10:44:00 http2: Framer 0xc000af61c0: wrote HEADERS flags=END_HEADERS stream=316 len=115

Notice the stream for the PUSH is 1511 but the above is the first time I see that Framer. And the rest are in the 300s. I don't exactly see how this happened.
There are multiple PUSH_PROMISE all with the same stream id which is also odd.

I truncated log-file after each successful request until it was hanged. Maybe that is why the log-file was broken.

I attach here other log-file, which was made when I caught problem from the first time. This log-file was never truncated.
http2.debug.log

@fraenkel, we prepared test application for problem reproducing. My apologies for so complicated app. We cannot extract some small piece of code, because we don't know where is the problem exactly.
I sent credentials to michael.fraenkel@gmail.com.

  1. Point Chromium-based browser to https://cardonecapital.hc04.dorofeev.me/.
  2. Press F12 and check "Disable cache" box.
  3. Press F5 until request will hangs.

To have more chances to catch the problem it should to remove proxy cache:

  1. Stop Caddy Server kill -SIGTERM <caddy process id>
  2. rm -fR /home/user/caddy-cache
  3. ./caddy run&

To patch or debug server:

  1. Custom cache plugin code is here: /home/user/smart-cache
  2. Caddy Server code is here: /home/user/go/src/github.com/caddyserver/caddy
  3. To rebuild Caddy:
  • cd /home/user/go/src/github.com/caddyserver/caddy/cmd/caddy
  • CGO_ENABLED=0 go build
  • mv ./caddy ~/caddy
  • cd
  • sudo setcap 'cap_net_bind_service=+ep' ./caddy
  • kill -SIGTERM <caddy process id>
  • ./caddy run&

@dtelyukh I did find a way to cause the hang locally, from my machine it would never happen.
for i in {1..1000}; do echo $i; nghttp https://cardonecapital.hc04.dorofeev.me/ -n; done would eventually hang.
Once I attempted to compile a new Go, I could never get caddy to rebuild. I always ended up with
qtls init failure. Attempting to fix that, I didn't realize at the time that the src tree was a bit special so I can no longer make any progress since I cannot download your smart-cache module.
If you could fix the tree, at least next time I know to make a copy of the entire tree before doing anything. I am a bit concerned that a simple go mod tidy prevented any further compilation of caddy.

So one thing I did verify is that using the latest golang/x/net/http2 code does not cause the hang I see with my simple testcase.

You can see the one line change I made to caddyserver with a go mod tidy. See if this new version hangs for you as well.

I believe this is fixed with Go 1.17 considering that the bundled http2 library was updated to a snapshot of x/net/http2 from May of this year.

@dtelyukh Can you give 1.17 a try with your test case (without manually using x/net/http2)?

@ReillyBrogan , I tried 1.17.3 - the problem still exists. I think, 1.18 could help.

Potentially fixed with #49921. It's part of the Go 1.17.6 release.
