Intermittent failure of cpp test jobs in CI

[kieran-ryan]

👓 What did you see?

Observed instances where the cpp jobs appear to have failed - with changes being unrelated to the cpp job itself e.g. modifying markdown files. For example, the following failed run on #215. Another failed run. Re-running the job for other PRs resulted in the job succeeding.

Download of latest Ninja build failing. Perhaps rate limiting or network issue?

✅ What did you expect to see?

Cpp job succeeds.

📦 Which tool/library version are you using?

Running with tooling versioned in repo against commit 579c66d.

🔬 How could we reproduce it?

Intermittent failure with pipelines. Not sure of root cause. Issue should arise with subsequent pipelines.

📚 Any additional context?

Apologies if raised under an existing issue - have not yet located.

author/maintainer of cpp port here, will keep an eye on that issue and hopefully find a proper solution to circumvent this problem tomorrow.

Noting a reoccurrence, just in case useful info that it wasn't a one-off - though works on retry so all good 👍

Yep, many thanks for the report @kieran-ryan, it's a timeout/connection reset while trying to download an additional build tool (ninja). A proper fix is in the way (half baked already). Will try to find some time and a bit of brain juice to tackle it.
Have a good day !
