Can you also add a description to HTTP3.md how to build this setup? |
- HTTP/3 for curl using OpenSSL's own QUIC stack together
with nghttp3
- configure with `--with-openssl-quic` to enable curl to
build this. This requires the nghttp3 library
- implementation with the following restrictions:
* macOS has to use an unconnected UDP socket due to an
issue in OpenSSL's datagram implementation
See openssl/openssl#23251
This makes connections to non-reponsive servers hang.
* GET requests will send the indicator that they have
no body in a separate QUIC packet. This may result
in processing delays or Transfer-Encodings on proxied
requests
* uploads that encounter blocks will use 100% cpu as
detection of these flow control issue is not working
(we have not figured out to pry that from OpenSSL).
- remove no longer neede config param in building openssl3
Done. |

It works with some manual hacks due to nghttp3 being undetected by autotools (a long-time issue). When enabled, the version string is showing some duplication: ``` curl 8.6.0-DEV (x86_64-w64-mingw32) libcurl/8.6.0-DEV OpenSSL/3.2.0 (Schannel) zlib/1.3 WinIDN libssh2/1.11.1_DEV nghttp2/1.58.0 OpenSSL/3.2.0 (Schannel) nghttp3/1.1.0 Release-Date: [unreleased] Protocols: dict file ftp ftps gopher gophers http https imap imaps ipfs ipns ldap ldaps mqtt pop3 pop3s rtsp scp sftp smb smbs smtp smtps telnet tftp ws wss Features: alt-svc AsynchDNS HSTS HTTP2 HTTP3 HTTPS-proxy IDN IPv6 Kerberos Largefile libz MultiSSL NTLM SPNEGO SSL SSPI threadsafe UnixSockets ``` Ref: curl/curl@0535f6e Ref: curl/curl#12734

Few observations after enabling support for this in curl-for-win:
|
|
@icing Can you add the cmake functionality / flag to compile http3 with openssl 3.2 + nghttp3 ? |
|
@talregev I must admit my cmake skills are lacking. |
|
I will open an issue about it. |
