# This file describes the stage0 compiler that's used to then bootstrap the Rust
|
|
# compiler itself.
|
|
#
|
|
# 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 is 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, with the previous
|
|
# stable release's version number. `date` is the date where the release we're
|
|
# bootstrapping off was released.

# 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.
