curl error on windows

[gaborcsardi]

─  Uploading package
Error in curl::curl_fetch_memory(url, handle = handle) : 
  Stream error in the HTTP/2 framing layer

[gaborcsardi]

@jeroenooms Have you seen this before?

[jeroen]

Yikes, no. Do you have a repro example?

[jeroen]

I did auto enable HTTP2 in the most recent windows release to see what would happen :)

[gaborcsardi]

Kinda. Not minimal. Take this package, clone it to windows. Install it, and start checking it on itself. So sg like:

devtools::install()
library(rhub)
validate_email(email = "...", token = "...")
check()

[jeroen]

You can always opt out of http2 like this. In this case 2 means CURL_HTTP_VERSION_1_1.

h <- new_handle(http_version = 2)

[jeroen]

What server are you using for http2?

[gaborcsardi]

I was not aware of using http2.....

Not sure what you mean for server, express.js, behind nginx. That's what
you mean?

Yeah I guess nginx has http/2 then? Either that or it's a bug in libcurl...

[gaborcsardi]

Yeah, it seems that http2 is turned on in my nginx config.

How do I specify the handle option for httr::POST (and GET, etc.) ?

(Need to go to sleep now, sorry.)

Yeah I can repro this on osx when I enable http2. Looks like a bug in libcurl... I have to go to sleep too, will look tomorrow :)

[gaborcsardi]

Thanks much!

[jeroen]

You can pass httr::config(http_version = 2) to the POST() or GET() to request. But I'd like to know if this is a server problem or a bug in libcurl. Because if it is the latter I should probably not automatically enable http2 when it is available.

[gaborcsardi]

Btw. it also fails on Linux, the same way, as you probably expected....

[gaborcsardi]

Also, there is no sign of the connection in the nginx logs.
