This reverts commit 8a1ca6cad9cd0e972c322910cdfbbe9552c6c7ca.
I have fixed 2 things:
* The report is now sent by stdin so we do not hit the limit on the size
of command line arguments.
* The report is limited to 1MB in size and if we exceed that we fall back
to listing only the totals with a note telling you to check the full log.
This reverts commit e74a002433b4cf7f891ceedb61bd862867218a8b.
As it is failing on Linux with "OSError: [Errno 7] Argument list too long: 'buildkite-agent'".
The CI builds now send the results of every lit run to a unique file.
This means we can read them all to make a combined report for all
tests.
This report will be shown as an "annotation" in the build results:
https://buildkite.com/docs/agent/v3/cli-annotate#creating-an-annotation
Here is an example:
https://buildkite.com/llvm-project/github-pull-requests/builds/112660
(make sure it is showing "All" instead of "Failures")
This is an alternative to using the existing Buildkite plugin:
https://github.com/buildkite-plugins/junit-annotate-buildkite-plugin
As the plugin is:
* Specific to Buildkite, and we may move away from Buildkite.
* Requires docker, unless we were to fork it ourselves.
* Does not let you customise the report format unless again,
we make our own fork.
Annotations use GitHub's flavour of Markdown so the main code in the
script generates that text. There is an extra "style" argument generated
to make the formatting nicer in Buildkite.
"context" is the name of the annotation that will be created. By using
different context names for Linux and Windows results we get 2 separate
annotations.
The script also handles calling the buildkite-agent. This makes passing
extra arguments to the agent easier, rather than piping the output of
this script into the agent.
In the future we can remove the agent part of it and simply use
the report content. Either printed to stdout or as a comment on
the GitHub PR.
