Re: [jetty-dev] "no content" timeout exception while upl multipart file

[Michele Rossi <michele.rossi@xxxxxxxxx>]

hi Simone,

thanks for looking into it!

The client in question is an R script which uses the HTTR library.

In turn, HTTR uses CURL.

https://cran.r-project.org/web/packages/httr/index.html

However at this moment I am unable to give you any version number as the person who works on it is on a different timezone but I will find out if it is of interest.

thanks again!

Michele

What client are you using ?

I ask because the logs show that the last DATA frame (line 12305)
arrives with the last 48 bytes that would make the total of 1489449
bytes as specified by the Content-Length, but that DATA frame has
end=false, while it should have end=true.

Because there is no indication that the stream has ended, Jetty waits
for more data from the client until it times out.

In HTTP/2 the framing is done by the end stream flags, not by the fact
that the Content-Length has been reached.

It appears to me a client bug.
