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`
Nix, the purely functional package manager
Nix is a new take on package management that is fairly unique. Because of its purity aspects, a lot of issues found in traditional package managers don't appear with Nix.
To find out more about the tool, usage and installation instructions, please read the manual, which is available on the Nix website at http://nixos.org/nix/manual.
