Abu	0495130e06	tests: improve error handling in main_test.go ... - Add t.Helper() to getCurrentGaugeValuesFor helper function for better error attribution in test failures - Add require.NoError checks for os.WriteFile calls in TestRuntimeGOGCConfig and TestHeadCompactionWhileScraping to catch file write failures - Strengthen error handling in TestDocumentation to assert command success rather than silently continuing on failure - Improve log message clarity in TestAgentSuccessfulStartup to accurately describe early exit scenario These changes improve test reliability and follow Go testing best practices.

Arve Knudsen	a5f86c3fb6	cmd/prometheus: fix flaky TestQueryLog race condition (#17933) ... Add waitForQueryLog helper that polls for query log entries to appear before asserting, rather than reading the file immediately after making a query. This fixes a race condition where the query log wasn't flushed to disk before the test read the file. The helper uses a 5 second timeout with 100ms polling intervals, which is generous enough to handle slow CI environments while keeping the test responsive.

Łukasz Mierzwa	8a1086a128	feat: Add flag that blocks lvl 1 compactions until upload is confirmed in an external JSON file (#17435) ... * Delay compactions until Thanos uploads all blocks Using Thanos sidecar with Prometheus requires us to disable TSDB compactions on Prometheus side by setting --storage.tsdb.min-block-duration and --storage.tsdb.max-block-duration to the same value. See https://thanos.io/tip/components/sidecar.md. The main problem this avoids is that Prometheus might compact given block before Thanos uploads it, creating a gap in Thanos metrics. Thanos does not upload compacted blocks because that would upload the same sample multiple times. You can tell Thanos to upload compacted blocks but that is aimed at one time migrations. This patch creates a bridge between Thanos and Prometheus by allowing Prometheus to read the shipper file Thanos creates, where it tracks which blocks were already uploaded, and using that data delays compaction of blocks until they are marked as uploaded by Thanos. Thanks to this both services can coordinate with each other (in a way) and we can stop disabling compaction on Prometheus side when Thanos uploads are enabled. The reason to have this is that disabling compactions have very dramatic performance cost. Since most time series exist for longer than a single block duration (2h by default) large chunks of block index will reference the same series, so 10 * 2h blocks will each have an index that is usually fairly big and is almost the same for all 10 blocks. Compaction de-duplicates the index so merging 10 blocks together would leave us with a single index that is around the same size as each of these 10 2h blocks would have (plus some extra for series that only exists in some blocks, but not all). Every range query that iterates over all 10 blocks would then have to read each index and so we're doing 10x more work then if we had a single compacted block.

Ayoub Mrini	e7999528fa	fix(test): make TestRemoteWrite_ReshardingWithoutDeadlock more reliable and re-enable it (#17490) ... Improve test stability by waiting for the relevant metrics to appear on /metrics before the first check on the desired shard count. Increase the scrape interval to avoid timeouts, as 100 ms may be insufficient for Prometheus to scrape itself in some environments (e.g., CI). Have Prometheus scrape itself multiple times to increase the volume of data sent and help fill the queue more quickly. Signed-off-by: machine424 <ayoubmrini424@gmail.com>	2025-11-25 21:30:42 +00:00
