Start monitoring updates of Git for Windows' component in the open
2021-08-17 00:17:32 +02:00
Johannes Schindelin
71566e2f51 Add a GitHub workflow to monitor component updates
Rather than using private IFTTT Applets that send mails to this
maintainer whenever a new version of a Git for Windows component was
released, let's use the power of GitHub workflows to make this process
publicly visible.

This workflow monitors the Atom/RSS feeds, and opens a ticket whenever a
new version was released.

Note: Bash sometimes releases multiple patched versions within a few
minutes of each other (i.e. 5.1p1 through 5.1p4, 5.0p15 and 5.0p16). The
MSYS2 runtime also has a similar system. We can address those patches as
a group, so we shouldn't get multiple issues about them.

Note further: We're not acting on newlib releases, OpenSSL alphas, Perl
release candidates or non-stable Perl releases. There's no need to open
issues about them.

fd47bb62ed Modify the GitHub Pull Request template (to reflect Git for Windows)
Git for Windows accepts pull requests; Core Git does not. Therefore we
need to adjust the template (because it only matches core Git's
project management style, not ours).

Also: direct Git for Windows enhancements to their contributions page,
space out the text for easy reading, and clarify that the mailing list
is plain text, not HTML.

dea98a5690 cmake(): allow setting HOST_CPU for cross-compilation
Git's regular Makefile mentions that HOST_CPU should be defined when cross-compiling Git: 37796bca76/Makefile (L438-L439)

This is then used to set the GIT_HOST_CPU variable when compiling Git: 37796bca76/Makefile (L1337-L1341)

Then, when the user runs `git version --build-options`, it returns that value: 37796bca76/help.c (L658)

This commit adds the same functionality to the CMake configuration. Users can now set -DHOST_CPU= to set the target architecture.

5e1c9b3853 git-artifacts: use the cached build-installers instead of makepkg-git
When building the Pacman packages, we technically do not need the full
`build-installers` artifact (which is substantially larger than the
`makepkg-git` artifact). However, the former is already cached and
includes the latter's files. And it is _so_ much faster to download the
cached (larger) artifact than to download the smaller `makepkg-git`
artifact from Azure Pipelines.

638a027aab git-artifacts: fix BUILD_ONLY handling for ARM64
The workflow allows users to restrict what parts are being built. For
example, `installer-i686` will build only the 32-bit installer, not the
64-bit one nor any MinGit flavor.

However, this logic was not extended when introducing support for ARM64:
Instead, we _also_ built the ARM64 installer when the user asked for
`installer-i686`.

Let's allow restricting to `installer-i686` _without_ building the ARM64
version, and allow restricting to `installer-arm64` _just_ for the ARM64
version.

4b0f57f9b5 git-artifacts: allow restricting which artifacts are built
Users can now specify which artifacts they want to build, via the
`build_only` input, which is a space-separated list of artifacts. For
example, `installer portable` will build `installer-x86_64`,
`installer-i686`, `portable-x86_64` and `portable-i686`, and an empty or
unset value will build all artifacts.

Please note that the `mingw-w64-git` packages are built always, as it
would be tricky to figure out when they need to be built (for example,
`build_only=portable-x86_64` technically does not need `pkg-i686` to be
built, while `build_only=portable` does).

a066a90db6 ci(check-whitespace): restrict to the intended commits
During a run of the `check-whitespace` we want to verify that the
commits introduced in the Pull Request have no whitespace issues. We
only want to look at those commits, not the upstream commits (because
the contributor cannot do anything about the latter).

However, by using the `-<count>` form in `git log --check`, we run the
risk of looking at the wrong commits. The reason is that the
`actions/checkout` step does _not_ check out the tip commit of the Pull
Request's branch: Instead, it checks out a merge commit that merges that
branch into the target branch. For that reason, we already adjust the
commit count by incrementing it, but that is not enough: if the upstream
branch has newer commits, they are traversed _first_. And obviously we
will then miss some of the commits that we _actually_ wanted to look at.

Therefore, let's be careful to stop assuming a linear, up to date commit
topology in the contributed commits, and instead specify the correct
commit range.

Unfortunately, this means that we no longer can rely on a shallow clone:
There is no way of knowing just how many commits the upstream branch
advanced after the commit from which the PR branch branched off. So
let's just go with a full clone instead, and be safe rather than sorry
(if we have "too shallow" a situation, a commit range `@{u}..` may very
well include a shallow commit itself, and the output of `git show
--check <shallow>` is _not_ pretty).

cc00362125 ci(check-whitespace): stop requiring a read/write token
As part of some recent security tightening, GitHub introduced the
ability to configure GitHub workflows to be run with a read-only token.
This is much more secure, in particular when working in a public
repository: While the regular read/write token might be restricted to
writing to the current branch, it is not necessarily restricted to
access only the current Pull Request.

However, the `check-whitespace` workflow threw a wrench into this plan:
it _requires_ write access (because it wants to add a PR comment in case
of a whitespace issue).

Let's just skip that PR comment. The user can always click through to
the actual error, even if it is slightly less convenient.

e61059660c ci: run make sparse as part of the GitHub workflow
Occasionally we receive reviews after patches were integrated, where
`sparse` (https://sparse.docs.kernel.org/en/latest/ has more information
on that project) identified problems such as file-local variables or
functions being declared as global.

By running `sparse` as part of our Continuous Integration, we can catch
such things much earlier. Even better: developers who activated GitHub
Actions on their forks can catch such issues before even sending their
patches to the Git mailing list.

This addresses https://github.com/gitgitgadget/git/issues/345

Note: Not even Ubuntu 20.04 ships with a new enough version of `sparse`
to accommodate Git's needs. The symptom looks like this:

    add-interactive.c:537:51: error: Using plain integer as NULL pointer

To counter that, we download and install the custom-built `sparse`
package from the Azure Pipeline that we specifically created to address
this issue.

d681d0dc3a ci (windows): transfer also the Git-tracked files to the test jobs
Git's test suite is excruciatingly slow on Windows, mainly due to the
fact that it executes a lot of shell script code, and that's simply not
native to Windows.

To help with that, we established the pattern where the artifacts are
first built in one job, and then multiple test jobs run in parallel
using the artifacts built in the first job.

We take pains in transferring only the build outputs, and letting
`actions/checkout` fill in the rest of the files.

One major downside of that strategy is that the test jobs might fail to
check out the intended revision (e.g. because the branch has been
updated while the build was running, as is frequently the case with the
`seen` branch).

Let's transfer also the files tracked by Git, and skip the checkout step
in the test jobs.

abb2b389f7 ci (vs-build): use cmd to copy the DLLs, not powershell
We use a `.bat` script to copy the DLLs in the `vs-build` job, and those
type of scripts are native to CMD, not to PowerShell.

0eb6c189a3 ci: use the new GitHub Action to download git-sdk-64-minimal
In our continuous builds, Windows is the odd cookie that requires a
complete development environment to be downloaded because there is no
suitable one installed by default on Windows.

Side note: technically, there _is_ a development environment present in
GitHub Actions' build agents: MSYS2. But it differs from Git for
Windows' SDK in subtle points, unfortunately enough so to prevent Git's
test suite from running without failures.

Traditionally, we support downloading this environment (which we
nicknamed `git-sdk-64-minimal`) via a PowerShell scriptlet that accesses
the build artifacts of a dedicated Azure Pipeline (which packages a tiny
subset of the full Git for Windows SDK, containing just enough to build
Git and run its test suite).

This PowerShell script is unfortunately not very robust and sometimes
fails due to network issues.

Of course, we could add code to detect that situation, wait a little,
try again, if it fails again wait a little longer, lather, rinse and
repeat.

Instead of doing all of this in Git's own `.github/workflows/`, though,
let's offload this logic to the new GitHub Action at
https://github.com/marketplace/actions/setup-git-for-windows-sdk

This Action not only downloads and extracts git-sdk-64-minimal _outside_
the worktree (making it no longer necessary to meddle with
`.gitignore` or `.git/info/exclude`), it also adds the `bash.exe` to the
`PATH` and sets the environment variable `MSYSTEM` (an implementation
detail that Git's workflow should never have needed to know about).

This allows us to convert all those funny PowerShell tasks that wanted
to call git-sdk-64-minimal's `bash.exe`: they all are now regular `bash`
scriptlets.

This finally lets us get rid of the funny quoting and escaping where we
had to pay attention not only to quote and escape the Bash scriptlets
properly, but also to add a second level of escaping (with backslashes
for double quotes and backticks for dollar signs) to stop PowerShell
from doing unintended things.

Further, this Action uses a fast caching strategy native to GitHub
Actions that should accelerate the download across CI runs:
git-sdk-64-minimal is usually updated once per 24h, and needs to be
cached only once within that period. Caching it (unfortunately only on
a per-branch basis) speeds up the download step, and makes it much more
robust at the same time by virtue of accessing a cache location that is
closer in the network topology.

With this we can drop the home-rolled caching where we try to accelerate
the test phase by uploading git-sdk-64-minimal as a workflow artifact
after using it to build Git, and then download it as workflow artifact
in the test phase.

Even better: the `vs-test` job no longer needs to depend on the
`windows-build` job. The only reason it depended on it was to ensure
that the `git-sdk-64-minimal` workflow artifact was available.

958a5f5dfe cmake(install): include vcpkg dlls
Our CMake configuration generates not only build definitions, but also
install definitions: After building Git using `msbuild git.sln`, the
built artifacts can be installed via `msbuild INSTALL.vcxproj`.

To specify _where_ the files should be installed, the
`-DCMAKE_INSTALL_PREFIX=<path>` option can be used when running CMake.

However, this process would really only install the files that were just
built. On Windows, we need more than that: We also need the `.dll` files
of the dependencies (such as libcurl). The `vcpkg` ecosystem, which we
use to obtain those dependencies, can be asked to install said `.dll`
files really easily, so let's do that.

This requires more than just the built `vcpkg` artifacts in the CI build
definition; We now clone the `vcpkg` repository so that the relevant
CMake scripts are available, in particular the ones related to defining
the toolchain.
