Julien	e34563bfe0	Retry SSE connection unless max clients have been reached. ... This switches from the prehistoric EventSource API to the more modern fetch-event-source package. That packages gives us full control over the retries. It also gives us the opportunity to close the event source when the browser tab is hidden, saving resources.

Julien	6cde0096e2	Add notifications to the web UI when configuration reload fails. ... This commit introduces a new `/api/v1/notifications/live` endpoint that utilizes Server-Sent Events (SSE) to stream notifications to the web UI. This is used to display alerts such as when a configuration reload has failed. I opted for SSE over WebSockets because SSE is simpler to implement and more robust for our use case. Since we only need one-way communication from the server to the client, SSE fits perfectly without the overhead of establishing and maintaining a two-way WebSocket connection. When the SSE connection fails, we go back to a classic /api/v1/notifications API endpoint. This commit also contains the required UI changes for the new Mantine UI.

Bryan Boreham	b8e5b7cda9	[REFACTOR] PromQL: remove label_join and label_replace stubs ... These functions operate on whole series, not on samples, so they do not fit into the table of functions that return a Vector. Remove the stub entries that were left to help downstream users of the code identify what changed. We cannot remove the entries from the `FunctionCalls` map without breaking `TestFunctionList`, so put some nils in to keep it happy.

Bryan Boreham	410fcce6f0	Remove unnecessary pprof import (#14988) ... The pattern of `import _ "net/http/pprof"` adds handlers to the default http handler, but Prometheus does not use that. There are explicit handlers in `web/web.go`. So, we can remove this line with no impact to behaviour. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2024-09-27 07:45:49 +01:00

I've made the testcases run in parallel and reduced the reload interval to 10ms. Now the test runs in around 0.1-0.2 seconds. Ran test 10000 times to check if it's flaky.

Bryan Boreham	7f99d2930d	[BUGFIX] PromQL: make sort_by_label stable ... Go's sorting functions can re-order equal elements, so the strategy of sorting by the fallback ordering first does not always work.

Craig Ringer	15b68e989c	Refer to staleness in instant vector documentation ... The instant vector documentation does not explain which metric samples are selected - in particular, it makes no reference to staleness. It's confusing when reading the docs to understand how exactly Prometheus selects the metrics to report: the most recent sample older than the search timestamp specified in the API request, so long as that metric is not "stale".
