Setting `http2 = false` in nix config (e.g. /etc/nix/nix.conf) had no effect, and `nix-env -vvvvv -i hello` still downloaded .nar packages using HTTP/2. In `src/libstore/download.cc`, the `CURL_HTTP_VERSION_2TLS` option was being explicitly set when `downloadSettings.enableHttp2` was `true`, but, `CURL_HTTP_VERSION_1_1` option was not being explicitly set when `downloadSettings.enableHttp2` was `false`. This may be because `https://curl.haxx.se/libcurl/c/libcurl-env.html` states: "You have to set this option if you want to use libcurl's HTTP/2 support." but, also, in the changelog, states: "DEFAULT Since curl 7.62.0: CURL_HTTP_VERSION_2TLS Before that: CURL_HTTP_VERSION_1_1" So, the default setting for `libcurl` is HTTP/2 for version >= 7.62.0. In this commit, option `CURLOPT_HTTP_VERSION` is explicitly set to `CURL_HTTP_VERSION_1_1` when `downloadSettings.enableHttp2` nix config setting is `false`. This can be tested by running `nix-env -vvvvv -i hello | grep HTTP` |
