The logic to skip testing on the tagged commit and the tag itself
was not quite consistent which led to failure of Windows test
tasks. It has been revamped to consistently skip revisions that
have already been tested, based on the tree object of the revision.
* js/ci-ghwf-dedup-tests:
ci: do not skip tagged revisions in GitHub workflows
ci: skip GitHub workflow runs for already-tested commits/trees

When pushing a commit that has already passed a CI or PR build
successfully, it makes sense to save some energy and time and skip the
new build.
Let's teach our GitHub workflow to do that.
For good measure, we also compare the tree ID, which is what we actually
test (the commit ID might have changed due to a reworded commit message,
which should not affect the outcome of the run).

It is the custom to follow minor updates of GitHub Actions
automatically, by using the suffix `@v1`. Actions' maintainers will then
update that `v1` ref to point to the newest.
However, for `microsoft/setup-msbuild`, 889cacb6897 (ci: configure
GitHub Actions for CI/PR, 2020-04-11) uses a very specific `@v1.0.0`
suffix.
In this instance, that is a problem: should `setup-msbuild` release a
new version that intends to fix a critical bug, we won't know it, and we
won't use it.
Such a scenario is not theoretical. It is happening right now:
https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands
Let's simplify our setup, allowing us to benefit from automatically
using the newest v1.x.

In the common case where users have _not_ pushed a `ci-config` branch to
configure which branches should be included in the GitHub workflow runs,
there is a big fat ugly annotation about a failure in the run's log:
X Check failure on line 1 in .github
@github-actions github-actions / ci-config
.github#L1
Process completed with exit code 128.
The reason is that the `ci-config` job tries to clone that `ci-config`
branch, and even if it is configured to continue on error, the
annotation is displayed, and it is distracting.
Let's just handle this on the shell script level, so that the job's step
is not marked as a failure.

The section added in e76eec35540f (ci: allow per-branch config for
GitHub Actions, 2020-05-07) contains a `&&`-chain that connects several
commands. The first command is actually so long that it stretches over
multiple lines, and as per usual, the continuation lines are indented one
more level than the first.
However, the subsequent commands in the `&&`-chain were also indented
one more level than the first command, which was almost certainly
unintended.

Aesthetic fix to a CI configuration file.
* am/ci-wsfix:
ci: fix inconsistent indentation
|
|
While YAML allows different indentation styles as long as each block
is consistent, it is rather unusual to mix different indentations in
a single file. Adjust to use two-space indentation everywhere.

Teach .github/workflows/main.yml to use CMake for VS builds.
Modified the vs-test step to match windows-test step. This speeds
up the vs-test. Calling git-cmd from powershell and then calling git-bash
to perform the tests slows things down(factor of about 6). So git-bash
is directly called from powershell to perform the tests using prove.
NOTE: Since GitHub keeps the same directory for each job
(with respect to path) absolute paths are used in the bin-wrapper
scripts.
GitHub has switched to CMake 3.17.1 which changed the behaviour of
FindCURL module. An extra definition (-DCURL_NO_CURL_CMAKE=ON) has been
added to revert to the old behaviour.
In the configuration phase CMake looks for the required libraries for
building git (eg zlib,libiconv). So we extract the libraries before we
configure.
To check for ICONV_OMITS_BOM libiconv.dll needs to be in the working
directory of script or path. So we copy the dlls before we configure.

Instead of downloading Windows SDK for CI jobs for windows builds
from an external site (wingit.blob.core.windows.net), use the one
created in the windows-build job, to work around quota issues at
the external site.
* js/ci-sdk-download-fix:
ci: avoid pounding on the poor ci-artifacts container

When this developer tested how the git-sdk-64-minimal artifact could be
served to all the GitHub workflow runs that need it, Azure Blobs looked
like a pretty good choice: it is reliable, fast and we already use it in
Git for Windows to serve components like OpenSSL, cURL, etc
It came as an unpleasant surprise just _how many_ times this artifact
was downloaded. It exploded the bandwidth to a point where the free tier
would no longer be enough, threatening to block other, essential Git for
Windows services.
Let's switch back to using the Build Artifacts of our trusty Azure
Pipeline for the time being.
To avoid unnecessary hammering of the Azure Pipeline artifacts, we use
the GitHub Action `actions/upload-artifact` in the `windows-build` job
and the GitHub Action `actions/download-artifact` in the `windows-test`
and `vs-test` jobs (the latter now depends on `windows-build` for that
reason, too).

Depending on the workflows of individual developers, it can either be
convenient or annoying that our GitHub Actions CI jobs are run on every
branch. As an example of annoying: if you carry many half-finished
work-in-progress branches and rebase them frequently against master,
you'd get tons of failure reports that aren't interesting (not to
mention the wasted CPU).
This commit adds a new job which checks a special branch within the
repository for CI config, and then runs a shell script it finds there to
decide whether to skip the rest of the tests. The default will continue
to run tests for all refs if that branch or script is missing.
There have been a few alternatives discussed:
One option is to carry information in the commit itself about whether it
should be tested, either in the tree itself (changing the workflow YAML
file) or in the commit message (a "[skip ci]" flag or similar). But
these are frustrating and error-prone to use:
- you have to manually apply them to each branch that you want to mark
- it's easy for them to leak into other workflows, like emailing patches
We could likewise try to get some information from the branch name. But
that leads to debates about whether the default should be "off" or "on",
and overriding still ends up somewhat awkward. If we default to "on",
you have to remember to name your branches appropriately to skip CI. And
if "off", you end up having to contort your branch names or duplicate
your pushes with an extra refspec.
By comparison, this commit's solution lets you specify your config once
and forget about it, and all of the data is off in its own ref, where it
can be changed by individual forks without touching the main tree.
There were a few design decisions that came out of on-list discussion.
I'll summarize here:
- we could use GitHub's API to retrieve the config ref, rather than a
real checkout (and then just operate on it via some javascript). We
still have to spin up a VM and contact GitHub over the network from
it either way, so it ends up not being much faster. I opted to go
with shell to keep things similar to our other tools (and really
could implement allow-refs in any language you want). This also makes
it easy to test your script locally, and to modify it within the
context of a normal git.git tree.
- we could keep the well-known refname out of refs/heads/ to avoid
cluttering the branch namespace. But that makes it awkward to
manipulate. By contrast, you can just "git checkout ci-config" to
make changes.
- we could assume the ci-config ref has nothing in it except config
(i.e., a branch unrelated to the rest of git.git). But dealing with
orphan branches is awkward. Instead, we'll do our best to efficiently
check out only the ci/config directory using a shallow partial clone,
which allows your ci-config branch to be just a normal branch, with
your config changes on top.
- we could provide a simpler interface, like a static list of ref
patterns. But we can't get out of spinning up a whole VM anyway, so
we might as well use that feature to make the config as flexible as
possible. If we add more config, we should be able to reuse our
partial-clone to set more outputs.

Arguably, CI builds' most important task is to not only identify
regressions, but to make it as easy as possible to investigate what went
wrong.
In that light, we will want to provide users with a way to inspect the
tests' output as well as the corresponding directories.
This commit adds build steps that are only executed when tests failed,
uploading the relevant information as build artifacts. These artifacts
can then be downloaded by interested parties to diagnose the failures
more efficiently.

This patch adds CI builds via GitHub Actions. While the underlying
technology is at least _very_ similar to that of Azure Pipelines, GitHub
Actions are much easier to set up than Azure Pipelines:
- no need to install a GitHub App,
- no need to set up an Azure DevOps account,
- all you need to do is push to your fork on GitHub.
Therefore, it makes a lot of sense for us to have a working GitHub
Actions setup.
While copy/editing `azure-pipelines.yml` into
`.github/workflows/main.yml`, we also use the opportunity to accelerate
the step that sets up a minimal subset of Git for Windows' SDK in the
Windows-build job:
- we now download a `.tar.xz` stored in Azure Blobs and extract it
simultaneously by calling `curl` and piping the result to `tar`,
- decompressing via `xz`,
- all three utilities are installed together with Git for Windows
At the same time, we also make use of the matrix build feature, which
reduces the amount of repeated text by quite a bit.
Also, we do away with the parts that try to mount a file share on which
`prove` can store data between runs. It is just too complicated to set
up, and most times the tree changes anyway, so there is little return on
investment there.
