- 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)
The tests on migration tests failed but CI reports successfully
https://github.com/go-gitea/gitea/actions/runs/7364373807/job/20044685969#step:8:141
This PR will fix the bug on migration v283 and also the CI hidden
behaviour.
The reason is on the Makefile
`GITEA_ROOT="$(CURDIR)" GITEA_CONF=tests/mysql.ini $(GO) test
$(GOTESTFLAGS) -tags='$(TEST_TAGS)' $(MIGRATE_TEST_PACKAGES)` will
return the error exit code.
But
`for pkg in $(shell $(GO) list
code.gitea.io/gitea/models/migrations/...); do \
GITEA_ROOT="$(CURDIR)" GITEA_CONF=tests/mysql.ini $(GO) test
$(GOTESTFLAGS) -tags '$(TEST_TAGS)' $$pkg; \
done`
will not work.
This also fix#29602
