test-infra uses go modules for Go dependency management. Usage requires bazel.
Run hack/update-deps.sh
whenever vendored dependencies change.
This takes a minute to complete, and
longer the more uncached repos golang needs to download.
New dependencies causes golang to recompute the minor version used for each major version of each dependency. And golang automatically removes dependencies that nothing imports any more.
Manually increasing the version of dependencies can be done in one of three ways:
bazel run //:update-patch # -- example.com/foo example.com/bar
- update everything (or just foo and bar) to the latest patch release
- aka
vX.Y.latest
bazel run //:update-minor # -- cloud.google.com/go/storage
- update everything (or just storage) to the latest minor release
- aka
vX.latest.latest
- Manually editing
go.mod
.
Always run hack/update-deps.sh
after changing go.mod
by any of these methods (or adding new imports).
See golang's go.mod and dependency upgrade docs for more details.
Use bazel run //:go -- whatever
rather than go whatever
from your $PATH
to ensure the correct version of golang is selected.
Note that using this path does not otherwise require golang to be installed on your workstation.
