tsdb: fix flaky TestBlockRanges by using explicit compaction
...
Replace polling loops (for range 100 { time.Sleep }) with explicit
db.Compact() calls after disabling background compaction, eliminating
CI flakiness on slow machines. Also fix incorrect overlap assertions
that were checking the wrong direction (LessOrEqual -> GreaterOrEqual).

Kahan summation is not perfect. This commit also adds tests that even Kahan summation cannot reliably pass.
These tests are commented out.
Note that the behavior might be different on other hardware platforms. We have to keep an eye on test failing on other hardware platforms and adjust them accordingly.

Scorecards supply-chain security / Scorecards analysis (push) Waiting to run
The tests were flaky because they used hard-coded time.After(550ms)
waits, which had only 50ms margin over WaitForPendingReadersInTimeRange's
500ms poll interval. On slow CI runners, this margin wasn't reliable.
Use synctest for deterministic time control:
- Wrap test logic in synctest.Test() to use fake time
- Use synctest.Wait() to let goroutines reach dormant state
- Use time.Sleep() to advance fake time past the poll interval
- No more timing-dependent assertions
This makes the tests both reliable and ~60x faster (0.05s vs 3s).
Fixes both TestWaitForPendingReadersInTimeRange and
TestWaitForPendingReadersInTimeRange_AppenderV2.

tsdb: fix division by zero in stale series compaction ( #17952 )
...
Guard the stale series ratio calculation by checking numSeries > 0
before computing the ratio. This prevents division by zero when
the head has no series.
Fixes #17949

It was 80 bytes with a lot of padding compared to the 56 bytes of the
original xor chunk iterator. Made it 64 bytes, tightly packed.

enhancement(tsdb): add test for LeveledCompactor stopping after excluding block
...
Add a test for `LeveledCompactor.Plan()` stopping after a block matches the
`BlockExcludeFilter`, as a sub-test
`TestLeveledCompactor/Plan/BlockExcludeFilter stops iteration`.
Also moving `TestLeveledCompactor_plan` to a sub-test
of `TestLeveledCompactor`, for consistency.

tsdb: add auto-cleanup to newTestHead and remove redundant cleanup calls ( #17890 )
...
Add automatic cleanup to newTestHeadWithOptions so that heads created
with newTestHead are automatically closed when the test ends. This
simplifies test code by removing the need for manual cleanup in most
cases.
Changes:
- Add t.Cleanup in newTestHeadWithOptions immediately after creating
the head, using _ = h.Close() to handle double-close gracefully
- Remove redundant t.Cleanup, defer, and explicit Close calls from
tests that use newTestHead
- Add cleanup for heads created with NewHead directly in restart
patterns (e.g., restartHeadAndVerifySeriesCounts, startHead)

* [TESTS] TSDB: Check that ListPostings are sorted
`newListPostings` is a convenient place to do this; move it into the
test file because it's not needed for anything else.
Also simplify the existing `SliceIsSorted` check.
Signed-off-by: Bryan Boreham <bjboreham@gmail.com>
* [COMMENTS] TSDB: Document that Postings are ordered.
The description of `Seek()` implies they are, but it's better to be explicit.
Signed-off-by: Bryan Boreham <bjboreham@gmail.com>
* [REFACTOR] Unexport ListPostings type
It's only used within the one package, and it would be surprising if
some downstream code did rely on this type, given all of its members
are unexported.

For tests only, we had various ways of opening DB. Reduced to one
instead of:
* Open
* newTestDB
* newTestDBOpts
* openTestDB
This so https://github.com/prometheus/prometheus/pull/17629 is smaller
and bit easier. Also for test maintainability and consistency.
