We're copying the binary to make sure we can call python3.exe around,
but it seems like the base image of GitHub Actions changed, copying the
file before we do so.
This commit changes the CI script to only copy the file if it doesn't
already exist.
Promote aarch64-pc-windows-msvc to Tier 2 Development Platform
Adds a GitHub Actions CI build for `aarch64-pc-windows-msvc` via cross-compilation on an x86_64 host.
This promotes `aarch64-pc-windows-msvc` from a Tier 2 Compilation Target (std) to a Tier 2 Development Platform (std+rustc+cargo+tools).
Fixes#72881
r? `@pietroalbini`
While waiting for a PR job to start testing my code, I noticed the
symlink-build-dir step took 10 minutes to complete, so I investigated
what caused that.
It seems like something changed in the build environment between version
20200901.1 (where the step took 45 seconds) and version 20200908.1
(where the step took 10 minutes). At the time of writing this commit,
the rust-lang organization is on vertsion 20200908.1, while the
rust-lang-ci organization is at version 20200901.1 (and is not affected
by this yet).
There is no need for this step anymore on GHA, as our XL builders got an
increase in the root paritition size, so this commit removes the code
that moved stuff around on GHA (while keeping it on Azure).
For the record, at the time of writing this, the disk situation is:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 667G 60G 607G 9% /
/dev/sdb1 110G 4.1G 101G 4% /mnt
This will render the src/ci/exec-with-shell.py script more or less
useless, but we're going to replace that by just using the system bash
instead.

Remove legacy InnoSetup GUI installer
On Windows the InnoSetup `.exe` installer was superseded by the MSI installer long ago. It's no longer needed.
The `.exe` installer hasn't been linked from the [other installation methods](https://forge.rust-lang.org/infra/other-installation-methods.html#standalone) page in many years. As far as I can tell the intent was always to remove this installer once the MSI proved itself. Though admittedly both installers feel very "legacy" at this point.
Removing this would mean we only maintain one Windows GUI installer and would speed up the distribution phase.
As a result of removing InnoSetup, this closes#24397
This commit changes our Windows CI to always use the latest Python
interpreter available in the GHA tool cache instead of hardcoding Python
3.7.6. This is needed because occasionally GitHub bumps the installed
version, deleting the previous one.
Stop explicitly depending on python 2
This PR revises our previous policy of officially only supporting and testing with python 2 in the CI environment to instead test with python 3. It also changes the defaults to python 3 in our various scripts (usually, by way of `python` rather than `python3` to preserve compatibility with systems that do not have a python 3 available).
The effect of this is that we expect all new patches to support python 3 (and will test as such). We explicitly also expect that patches support python 2.7 as well -- and test as such, though only on one builder. This is intended as a temporary, though likely long-lived, measure to preserve compatibility while looking towards the future which is likely to be a python 3 only world. We do not at this point set a timeline for when we'll drop support for python 2.7; it's plausible that this is months or years into the future, depending on how quickly the ecosystem drops support and how painful it is for us to maintain that support over time.
Closes#65063 (as far as I can tell; please file explicit and separate issues or PRs if not).
There are some builders that are running out of disk space while
building the Docker images, such as arm-android. This moves and symlinks
/var/lib/docker to the /mnt partition on Linux GHA.
The /mnt mount point has 53GB of free disk space at the time of writing
this commit, so this moves the build there to avoid running out of disk
space during builds.
On Azure Pipeliones, the C: filesystem is huge with a lot of free space,
while D: is small. By default builds happened in D:, so we added a
script to symlink the big directories to C:, granting us more space.
Filesystem Size Used Avail Use%
C: 256G 143G 114G 56%
D: 14G 2.0G 13G 15%
On GitHub Actions instead C: is almost full, and we have a lot of free
space on D:, where the build happens.
Filesystem Size Used Avail Use%
C: 128G 114G 15G 89%
D: 56G 4.8G 52G 9%
This commit stops creating the symlink on GitHub Actions, fixing the out
of disk space errors we were seeing on some Windows builders.
Apparently the old path we were using for Python 2 on Windows was not
documented, and eventually got removed. This switches our CI to use the
correct path.
This helps us have enough disk space for our builders to be able to complete
successfully. For now, the choices are ad-hoc and 'definitely not needed'. This
should never fail the build, as everything our build needs should be inside
Docker.
In their infinite wisdom, Apple decided that (starting from macOS 10.15
onwards) /usr/include is not the location we should all search in for
our beloved C headers. Instead, we should look inside the extremely
intuitive and easily guessable new path:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include
Because why not.
Some environment variables (like DEPLOY or DEPLOY_ALT for dist builders,
or IMAGE on Linux builders) are set on a lot of builders, and whether
they should be present or not can be detected automatically based on the
builder name and the platform.
This commit simplifies the CI configuration by automatically setting
those environment variables.
This commit replaces the mirrors base URL contained in the MINGW_URL
with a CUSTOM_MINGW=1 environment variable. The mirrors base URL will be
fetched instead through the MIRRORS_BASE environment variable, defined
in src/ci/shared.sh.
ci: revert msys2 ca-certificates hack
The hack was added because upstream msys2 broke the ca-certificates package, but since then it has been fixed. This reverts CI to use the upstream package.
