The sample EOL DB for homebrew testing is outdated

[stefanb]

👋 Hey, Homebrew maintainer here.

There is a special case for homebrew test built into xeol:

xeol/xeol/db/curator.go

Lines 201 to 221 in fec1277

	isBrewTest := os.Getenv("HOMEBREW_GITHUB_ACTIONS")
	if isBrewTest == "1" {
	sampleEntry := ListingEntry{
	Built: time.Now(),
	Version: 1,
	Checksum: "sha256:8c3188056b129e55272b8d6c25cb9e27de59ec02b23c1a4c0e98f17d22333a31",
	URL: &url.URL{
	Scheme: "https",
	Host: "s3.us-east-1.amazonaws.com",
	Path: "/data.xeol.io/xeol/databases/sample.tar.gz",
	},
	}
	sampleMeta := Metadata{
	Built: time.Now(),
	Version: 1,
	Checksum: "sha256:8c3188056b129e55272b8d6c25cb9e27de59ec02b23c1a4c0e98f17d22333a31",
	}
	log.Infof("homebrew sample url: %s", sampleEntry)
	return true, &sampleMeta, &sampleEntry, nil
	}

Instead of the real database it is referencing an outdated one, causing a test failure with error

db could not be loaded: the eol database was built 17 weeks ago (max allowed age is 12 weeks)

Please either

• remove this exception to let homebrew use the real (current, EDIT: possibly too big) database or
• regularly update the sample database on the given URL or
• adjust also the database age check for homebrew

The first option would provide most realistic check, but the real DB may be too big for the tests (see #504).

• xeol: turn off brew specific test Homebrew/homebrew-core#238790

The previous homebrew test fix now just improves the test:
