1 | # This file describes the stage0 compiler that's used to then bootstrap the Rust |
2 | # compiler itself. For the rustbuild build system, this also describes the | |
3 | # relevant Cargo revision that we're using. | |
4 | # | |
476ff2be | 5 | # Currently Rust always bootstraps from the previous stable release, and in our |
a7813a04 XL |
6 | # train model this means that the master branch bootstraps from beta, beta |
7 | # bootstraps from current stable, and stable bootstraps from the previous stable | |
8 | # release. | |
9 | # | |
10 | # If you're looking at this file on the master branch, you'll likely see that | |

11 | # rustc and cargo are configured to `beta`, whereas if you're looking at a |
12 | # source tarball for a stable release you'll likely see `1.x.0` for rustc and | |
13 | # `0.x.0` for Cargo where they were released on `date`. | |

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

25 | # When making a stable release the process currently looks like: | |
26 | # | |
27 | # 1. Produce stable build, upload it to dev-static | |
28 | # 2. Produce a beta build from the previous stable build, upload to static | |
29 | # 3. Produce a nightly build from previous beta, upload to static | |
30 | # 4. Upload stable build to static, publish full release | |
31 | # | |
32 | # This means that there's a small window of time (a few days) where artifacts | |
33 | # are downloaded from dev-static.rust-lang.org instead of static.rust-lang.org. | |

34 | # In order to ease this transition we have an extra key which is in the |
35 | # configuration file below. When uncommented this will instruct the bootstrap.py | |
36 | # script to download from dev-static.rust-lang.org. | |

38 | # This key is typically commented out at all times. If you're looking at a | |
39 | # stable release tarball it should *definitely* be commented out. If you're | |
40 | # looking at a beta source tarball and it's uncommented we'll shortly comment it | |
41 | # out. | |
