- Go's deadcode eliminator is quite simple, if you put a public function in a package `aa/bb` that is used only by tests, it would still be built if package `aa/bb` was imported. This means that if such functions use libraries relevant only to tests that those libraries would still be be built and increase the binary size of a Go binary. - This is also the case with Forgejo, `models/migrations/base/tests.go` contained functions exclusively used by tests which (skipping some steps here) imports https://github.com/ClickHouse/clickhouse-go, which is 2MiB. The `code.gitea.io/gitea/models/migrations/base` package is imported by `cmd/doctor` and thus the code of the clickhouse library is also built and included in the Forgejo binary, although entirely unused and not reachable. - This patch moves the test-related functions to their own package, so Go's deadcode eliminator knows not to build the test-related functions and thus reduces the size of the Forgejo binary. - It is not possible to move this to a `_test.go` file because Go does not allow importing functions from such files, so any test helper function must be in a non-test package and file. - Reduction of size (built with `TAGS="sqlite sqlite_unlock_notify" make build`): - Before: 95912040 bytes (92M) - After: 92306888 bytes (89M)
