Nginx HTTP/2 patch disabled or breaks ngx_pagespeed under SSL

[centminmod]

Nginx has released first HTTP/2 alpha patch https://www.nginx.com/blog/early-alpha-patch-http2/ and that seems to break ngx_pagespeed for HTTP/2 SSL based sites https://community.centminmod.com/posts/17342/

I get in ngx_pagespeed message log for https://sslspdy.com site which is using Nginx 1.9.3 patched with HTTP/2

Looks like HTTP/2 + ngx_pagespeed also causes webpagetest.org first view tests to timeout too - results at http://www.webpagetest.org/result/150814_8Y_3baf06f884a7d89a38dd4e71e2fced9c/

What happens if you set pagespeed FetchHttps enable; ?

[jeffkaufman]

(It looks like by "broken" you mean "optimizations that require fetching no longer work?)

[centminmod]

pagespeed FetchHttps enable; still results in broken = mean optimisations and page elements are no longer rewritten - probably due to failed fetching.

You can see in webpagetest results I posted http://www.webpagetest.org/video/view.php?id=150814_d7da92402b5099925a448e3018ad683ca920bfe0&data=1

Added Nginx SPDY/3.1 results too https://centminmod.com/http2-versus-spdy-nginx.html

• Nginx SPDY/3.1 + ngx_pagespeed http://www.webpagetest.org/result/150815_9Z_302da2367e8e1ad31c7276e92242021a/
• Nginx SPDY/3.1 + ngx_pagespeed disabled http://www.webpagetest.org/result/150815_PY_71d552c88602940500a27b4d25394b67/

Nginx SPDY/31 + ngx_pagespeed works fine. Nginx HTTP/2 + ngx_pagespeed doesn't as pagespeed doesn't get to rewrite resources and optimise them

[centminmod]

Nginx released HTTP/2 version 2 patch http://nginx.org/patches/http2/ and it seems to have fixed ngx_pagespeed issue !

[jeffkaufman]

Great! Glad it's working now!

When the patch gets closer to ready we'll start testing against it here.

[skynet]

How about the official version https://www.nginx.com/blog/nginx-1-9-5/ Did it fix this problem?

[arfaWong]

@centminmod nginx-1.9.5 fix it？

[skynet]

@ranbokun We got this version installed but didn't get as far as trying to reproduce this particular bug.

[centminmod]

@ranbokun was fixed in nginx http/2 alpha patch ver 2 onwards, so final 1.9.5 already works fine - running nginx 1.9.5 + nginx pagespeed + http/2 for my forums https://community.centminmod.com/ :)

[skynet]

@centminmod excellent thank you!

[HomeTriangle]

@centminmod We are also using the same combo.
nginx 1.9.5 + nginx pagespeed + http/2 . Working smooth. Getting 100ms improvement in page rendering

[skynet]

@HomeTriangle Nginx is already at 1.9.7: http://nginx.org/en/CHANGES
