   1 # This file describes the stage0 compiler that's used to then bootstrap the Rust
   2 # compiler itself.
   3 #
   4 # Currently Rust always bootstraps from the previous stable release, and in our
   5 # train model this means that the master branch bootstraps from beta, beta
   6 # bootstraps from current stable, and stable bootstraps from the previous stable
   7 # release.
   8 #
   9 # If you're looking at this file on the master branch, you'll likely see that
  10 # rustc is configured to `beta`, whereas if you're looking at a source tarball
  11 # for a stable release you'll likely see `1.x.0` for rustc, with the previous
  12 # stable release's version number. `date` is the date where the release we're
  13 # bootstrapping off was released.
  14
  15 date: 2021-06-17
  16 rustc: 1.53.0

  18 # We use a nightly rustfmt to format the source because it solves some
  19 # bootstrapping issues with use of new syntax in this repo. If you're looking at
  20 # the beta/stable branch, this key should be omitted, as we don't want to depend
  21 # on rustfmt from nightly there.
  22 # rustfmt: nightly-2021-03-25

  24 # When making a stable release the process currently looks like:
  25 #
  26 #   1. Produce stable build, upload it to dev-static
  27 #   2. Produce a beta build from the previous stable build, upload to static
  28 #   3. Produce a nightly build from previous beta, upload to static
  29 #   4. Upload stable build to static, publish full release
  30 #
  31 # This means that there's a small window of time (a few days) where artifacts
  32 # are downloaded from dev-static.rust-lang.org instead of static.rust-lang.org.
  33 # In order to ease this transition we have an extra key which is in the
  34 # configuration file below. When uncommented this will instruct the bootstrap.py
  35 # script to download from dev-static.rust-lang.org.
  36 #
  37 # This key is typically commented out at all times. If you're looking at a
  38 # stable release tarball it should *definitely* be commented out. If you're
  39 # looking at a beta source tarball and it's uncommented we'll shortly comment it
  40 # out.
