Switch our CDash submissions from my.cdash.org to our self-hosted instance at https://cdash.fish.foo/index.php?project=bitcoin-core.

my.cdash.org sometimes deletes our logs extremely quickly. That leaves too little time to investigate failures and makes links to earlier results 404, which is annoying.

The new instance runs on a dedicated Hetzner VPS and gives us control over retention. Submissions are configured to be retained for 90 days, and the project's build retention is also set to 90 days.

ACK 10b75a659efed96ff4d21abb023b8786825f7643.

Perhaps it makes sense to mention the link to the dashboard somewhere in the test docs to make it easy to discover.

This also changes the nightly start time from 00:00 UTC to 01:23 UTC (slightly "randomised" from 00:00 to reduce contention on nightlies).

CTEST_NIGHTLY_START_TIME is not used as a job start trigger, so it cannot cause any contention. Rather, it serves as the boundary between "days".

willcl-ark commented at 2:40 PM on November 10, 2026:

Oh, nice. Well I'll reset that to 00:00 UTC then!

ci: Switch to self-hosted CDash

my.cdash.org sometimes deletes our logs in under a week, leaving too
little time to investigate failures or refer back to earlier results.

Submit results to cdash.fish.foo, our own CDash instance hosted on a
dedicated Hetzner VPS, so we can control retention. It is currently
configured to retain log submissions for 90 days.
