[redbean] big POST Fetch() request fails with "tls write failed (UNKNOWN ERROR CODE (4000) -0xffffc000)"

[elitepleb]

Using Fetch() to upload files with multipart/form-data encoding might not be it's intended use, but it's the situation i've found myself in.

It seems to fail at around 16kb, and setting a bigger ProgramMaxPayloadSize does not help.

Minimal reproduction with a public http dump service in interpreter mode Works Fetch('https://httpdump.app/dumps/{uuid}', {method="POST", body = "a" * (1024*16 - 155) }) Fails printing nil "tls write failed (UNKNOWN ERROR CODE (4000) -0xffffc000)" Fetch('https://httpdump.app/dumps/{uuid}', {method="POST", body = "a" * (1024*16 - 154) })

Really loving working with redbean and fullmoon so far though, great work!

@elitepleb, thank you for the report and the test case. I'd say it's intended use, so would expect it to work. I'll have a chance to check it later today to confirm. Just to be clear, what OS are you running this on? Does --strace option show anything interesting before the error? Thanks!

Linux and Windows, latest available redbean-2.0.17.com build. Behavior repeats with and without assimilation.

--strace dump does not seem to show anything interesting
