asmhatreandClaude Sonnet 5 67e1b2d8a9 db-migrations-flyway-liquibase: fix dead Redgate/Liquibase doc links and back the lock-defaults claim with a real transcript
Several documentation.red-gate.com and liquibase.com URLs added in the previous commit had
since moved (Redgate restructured its docs under /flyway/reference/, Liquibase Pro pricing
moved to /pricing); this repoints them at the current, verified-200 pages. Also captures
docs/output/16-liquibase-lock-defaults-javap.txt, the trimmed javap output backing chapter
11's claim about Liquibase's default lock-poll and lock-wait settings, which chapter 11
previously asserted without a committed artifact to back it.

12. The OSS license service

← 11. Liquibase locking · Index · Next: 13. The FSL license change →

Chapter 7 found that Flyway Community gates certain commands behind a runtime FlywayRedgateEditionRequiredException. Liquibase Community 5.0 shipped something new alongside its license change (chapter 13): a liquibase.license package, inside liquibase-core itself, that didn't exist in 4.x. LiquibaseLicenseServiceTest doesn't read about what that package does — it asks the actual service Spring Boot's LiquibaseAutoConfiguration runs on top of, directly:

implementation: liquibase.license.OSSLicenseService
licenseIsInstalled(): false
licenseIsValid("any"): false
getLicenseInfo(): ""

(from docs/output/14-liquibase-oss-license-service.txt)

On the classpath this module uses — Community only, no Liquibase Pro artifact anywhere — the license service Liquibase actually wires up is OSSLicenseService, which reports itself as unlicensed and returns an empty license description. This test found no evidence of functional gating anywhere in the classpath this module runs on: update(), rollback(), and every changeset type this module exercises worked identically whether or not a license was present, because none of them ever asked the license service anything. That's a meaningfully different shape from Flyway's stub-and-throw pattern in chapter 7 — Liquibase Pro's paid features live in separate, additional artifacts rather than as gated stubs inside the Community jar.

Going deeper

  • This test is a snapshot of Liquibase 5.0.3's Community classpath, not a guarantee about future releases — the license service's existence at all, brand new in 5.0, is itself evidence that Liquibase's commercial boundary is actively being redrawn (chapter 13 covers why).
  • Liquibase Pro feature comparison (rel="nofollow") — what Pro actually adds, as separate functionality rather than unlocked stubs.
