| # This file describes the stage0 compiler that's used to then bootstrap the Rust |
| # compiler itself. For the rustbuild build system, this also describes the |
| # relevant Cargo revision that we're using. |
| # |
| # Currently Rust always bootstraps from the previous stable release, and in our |
| # train model this means that the master branch bootstraps from beta, beta |
| # bootstraps from current stable, and stable bootstraps from the previous stable |
| # release. |
| # |
| # If you're looking at this file on the master branch, you'll likely see that |
| # rustc and cargo are configured to `beta`, whereas if you're looking at a |
| # source tarball for a stable release you'll likely see `1.x.0` for rustc and |
| # `0.x.0` for Cargo where they were released on `date`. |
| |
| date: 2020-03-12 |
| rustc: 1.42.0 |
| cargo: 0.43.0 |
| |
| # We use a nightly rustfmt to format the source because it solves some |
| # bootstrapping issues with use of new syntax in this repo. If you're looking at |
| # the beta/stable branch, this key should be omitted, as we don't want to depend |
| # on rustfmt from nightly there. |

| |
| # When making a stable release the process currently looks like: |
| # |
| # 1. Produce stable build, upload it to dev-static |
| # 2. Produce a beta build from the previous stable build, upload to static |
| # 3. Produce a nightly build from previous beta, upload to static |
| # 4. Upload stable build to static, publish full release |
| # |
| # This means that there's a small window of time (a few days) where artifacts |
| # are downloaded from dev-static.rust-lang.org instead of static.rust-lang.org. |
| # In order to ease this transition we have an extra key which is in the |
| # configuration file below. When uncommented this will instruct the bootstrap.py |
| # script to download from dev-static.rust-lang.org. |
| # |
| # This key is typically commented out at all times. If you're looking at a |
| # stable release tarball it should *definitely* be commented out. If you're |
| # looking at a beta source tarball and it's uncommented we'll shortly comment it |
| # out. |
