rustup show should not force-install the default toolchain if it is not installed. #1397
Description
This behavior confused me:
$ rustup uninstall nightly-2018-04-01-x86_64-apple-darwin info: uninstalling toolchain 'nightly-2018-04-01-x86_64-apple-darwin' info: toolchain 'nightly-2018-04-01-x86_64-apple-darwin' uninstalled $ rustup show Default host: x86_64-apple-darwin info: syncing channel updates for 'nightly-2018-04-01-x86_64-apple-darwin' info: latest update on 2018-04-01, rust version 1.26.0-nightly (517f24025 2018-03-31) info: downloading component 'rustc' 57.3 MiB / 57.3 MiB (100 %) 7.8 MiB/s ETA: 0 s info: downloading component 'rust-std' 46.2 MiB / 46.2 MiB (100 %) 7.4 MiB/s ETA: 0 s info: downloading component 'cargo' 3.0 MiB / 3.0 MiB (100 %) 1.5 MiB/s ETA: 0 s info: downloading component 'rust-docs' 6.8 MiB / 6.8 MiB (100 %) 3.1 MiB/s ETA: 0 s info: installing component 'rustc' info: installing component 'rust-std' info: installing component 'cargo' info: installing component 'rust-docs' installed toolchains -------------------- stable-x86_64-apple-darwin nightly-i686-apple-darwin nightly-x86_64-apple-darwin (default) active toolchain ---------------- nightly-2018-04-01-x86_64-apple-darwin (directory override for '/Users/user/GitHub/unrust') rustc 1.26.0-nightly (517f24025 2018-03-31) Is rustup show supposed to actually start installing components? I was under the impression that it was just for listing out what you have installed.
