From d17874ff601c53ac35f71e55f5629a5b8232d678 Mon Sep 17 00:00:00 2001 From: Pietro Albini Date: Tue, 17 Nov 2020 12:52:21 +0100 Subject: [PATCH] bootstrap: use the same version number for rustc and cargo Historically the stable tarballs were named after the version number of the specific tool, instead of the version number of Rust. For example, both of the following tarballs were part of the same release: rustc-1.48.0-x86_64-unknown-linux-gnu.tar.xz cargo-0.49.0-x86_64-unknown-linux-gnu.tar.xz PR #77336 changed the dist code to instead use Rust's version number for all the tarballs, regardless of the tool they contain: rustc-1.48.0-x86_64-unknown-linux-gnu.tar.xz cargo-1.48.0-x86_64-unknown-linux-gnu.tar.xz Because of that there is no need anymore to have a separate `cargo` field in src/stage0.txt, as the Cargo version will always be the same as the rustc version. This PR removes the field, simplifying the code and the maintenance work required while producing releases. --- src/bootstrap/bootstrap.py | 29 ++++------------------------- src/stage0.txt | 11 +++++------ 2 files changed, 9 insertions(+), 31 deletions(-) diff --git a/src/bootstrap/bootstrap.py b/src/bootstrap/bootstrap.py index 54d0a23dec5..4fb58034ce2 100644 --- a/src/bootstrap/bootstrap.py +++ b/src/bootstrap/bootstrap.py @@ -360,7 +360,6 @@ def output(filepath): class RustBuild(object): """Provide all the methods required to build Rust""" def __init__(self): - self.cargo_channel = '' self.date = '' self._download_url = '' self.rustc_channel = '' @@ -387,7 +386,6 @@ class RustBuild(object): will move all the content to the right place.
