node-spdy incompatible with node >= v15

[therealgilles]

I've been using spdy 4.0.2 for some time without a hitch and am suddenly getting http2 protocol errors with 'Server reset stream'. http/1.1 works.

This is what I see in the browser: Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR

Wondering why that could and how I can debug the issue. Any advice would be appreciated.

Here is a log extract showing the abort and the RST_STREAM:

Turns out it works with node v14.15.1 and breaks with node v15.4.0. Something must have changed in node v15 that broke http/2.

[anikolov]

I experience the same problem - it is not working with node v15.8.0 and express-session, but it works just fine if you don't set a cookie. I confirm that it works with node v14.15.5 and express-session.

[therealgilles]

Thanks for the report @anikolov.

[multicron]

I also have this happening, with Node 15.8.0 but not with 14.15.4. express 4.17.1, spdy 4.0.2.

With node 16.0.0 gives a deprecation warning: (node:34788) [DEP0111] DeprecationWarning: Access to process.binding('http_parser') is deprecated. At least the trace obtained with --trace-deprecation starts at spdy/handle.js loading.

[Upd4ting]

Any progress with that?

With node 16.0.0 gives a deprecation warning: (node:34788) [DEP0111] DeprecationWarning: Access to process.binding('http_parser') is deprecated. At least the trace obtained with --trace-deprecation starts at spdy/handle.js loading.

I doubt this is the root cause, as DEP0111 is documented-only deprecation for now. Ref: https://nodejs.org/api/deprecations.html#DEP0111

Nevertheless, I have submitted a pull request to patch the upcoming deprecation. Ref: https://github.com/spdy-http2/http-deceiver/pull/7

[lamweili]

I did some testing and here are my findings to assist in finding the root cause of the incompatibility.

nodejs	express	spdy	http1.1	http2
17.3.1	4.17.1	4.0.2	:heavy_check_mark:	:x:
17.0.0	4.17.1	4.0.2	:heavy_check_mark:	:x:
16.13.1	4.17.1	4.0.2	:heavy_check_mark:	:x:
16.0.0	4.17.1	4.0.2	:heavy_check_mark:	:x:
15.14.0	4.17.1	4.0.2	:heavy_check_mark:	:x:
15.0.0	4.17.1	4.0.2	:heavy_check_mark:	:x:
14.18.2	4.17.1	4.0.2	:heavy_check_mark:	:heavy_check_mark:
14.0.0	4.17.1	4.0.2	:heavy_check_mark:	:heavy_check_mark:

Even after manually applying both pull requests that resolves DEP0066 and DEP0111, I have the same results.

DEP0066 PR - https://github.com/spdy-http2/node-spdy/pull/367 DEP0111 PR - https://github.com/spdy-http2/http-deceiver/pull/7

The compatibility issue started from NodeJS 15.0.0.

Any updates on this ?

[vmcodes]

@nmargaritis I forked this repo and committed some previous PRs to my fork, but I'm not knowledgeable enough to contribute much besides the deprecated packages I was able to update. If anyone would like to contribute in any way, I'd be glad to attempt to maintain the fork.

It seems to me node is behind with regards to newer http protocols - the only viable http2 option is this(forcing usage of node 14, whose EOL is in about a year).

node 16 support is critical

Bump

I've got the same issue with NodeJS 20
