- 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)
Because the `git` module did not recognize SSH signed tags, those
signatures ended up in the `notes` column of the `release` table. While
future signatures will not end up there, Forgejo should clean up the old
ones.
This migration does just that: finds all releases that have an SSH
signature, and removes those signatures, preserving the rest of the
note (if any).
While this may seem like an expensive operation, it's only done once,
and even on the largest known Forgejo instance as of this
writing (Codeberg), the number of affected rows are just over a hundred,
a tiny amount all things considered.
