I do think this is a conversation worth having -- at least, it would make sense to me to not ship these components on beta/stable, since to my knowledge no one (should be) using them there; even we don't do so in-tree. I think in some sense this is also a broader question than just release team, though I'm not sure what teams I'd include necessarily. I guess maybe compiler and infra teams? |

This seems like an excellent idea! One wonders why we haven't done this before... |

(Summary from discussion on Discord): I think we should move out the sanitizers (tsan, lsan, msan, asan) from the rust-std component as well. In total they account for 14M which is 8% of 171M -- that's not nothing. Also worth noting that the sanitizers are unstable (see #47174) and not available on all tier-1 targets (e.g. macOS). Many people have no clue how to use them, including myself. |

Oh, the sanitizers are a direct dependency of Lines 37 to 45 in ddf4386 |

You need them to cross compile for example miri. |

I personally am not sure who all should be in charge of this decision so I'll try and bring it up at core team meeting tomorrow. I myself believe this to be a good step to take presuming it doesn't break anything for our own shipped tools (RLS, clippy). |

I'm not sure if I'll make it to triage this afternoon but wanted to say that I'm also in favor of this, it's indeed a bummer that a few hundred never-used megabytes are downloaded for only wanting libstd! I do think that separation into |

FWIW this is being reverted in #65342 because of the problems it caused. |

Since it was reverted due to problems, is this pullrequest going to be rebooted at some point in the future? |
Split the rustc target libraries into separate rustc-dev component This is re-applies a squashed version of #64823 as well as including #65337 to fix bugs noted after merging the first PR. The second PR is confirmed as fixing windows-gnu, and presumably also fixes other platforms, such as musl (i.e. #65335 should be fixed); `RUSTUP_DIST_SERVER=https://dev-static.rust-lang.org rustup toolchain install nightly-2019-10-16` can be installed to confirm that this is indeed the case.

pr65474 minimizes the amount of files needed for the install of a rust-std component by not merging certain dev-header files and other instable components. more information: rust-lang/rust#64823 rust-lang/rust#65474 I opted for +-r1 and dropped keywords, for testing. Also included pr66103, it shouldn't hurt anyone. Signed-off-by: Steffen Kuhn <nielson2@yandex.com>

This enables to compile rls and rustc See also rust-lang/rust#64823
This changes the
rust-stddist component to only include the artifacts of compiling thelibstdstep, as listed in.libstd.stamp. This does includetestandproc-macroas well. The remaining unstable libraries that are built as part ofrustcare packaged into a newrustc-devcomponent, intended for use in the development of closely related tools (clippy, miri, rls).Here are the component sizes from the try build:
