# Why
Release/backport branches (`v3-1-test`, `v3-2-test`, ...) often lack
`go-sdk`/`java-sdk` entirely or
carry a stale, branch-cut-frozen copy, so backporting a core/task-sdk fix to
such a branch would
silently run the lang-SDK coordinator k8s test against missing or outdated
SDK sources.
## What
- Added `_lang_sdk_fetch_upstream_sdk_sources()`: shallow-fetches upstream
`main` (`upstream` remote if
configured, else the canonical GitHub URL) and extracts
`go-sdk`/`java-sdk` into a throwaway staging
dir via `git archive`, never touching the real working tree.
- Go build now runs against a scratch workspace mirroring `go_example`'s
relative layout with `go-sdk`
swapped for the upstream copy (its `go.mod` `replace` is a filesystem
path, so this avoids editing
it). Java build simply points gradle at the upstream `java-sdk` copy
instead of the local one.
- `airflow-core/`, `task-sdk/`, and the test's own harness fixtures
(`go_example`/`java_example`) are
untouched and keep tracking the checked-out branch. `providers/` is out of
scope (unused by this test;
overlaying it into the shared PROD image build isn't worth the
invasiveness).
- Lives entirely in breeze (`kubernetes_commands.py`), so it applies to both
CI and local
`breeze k8s setup-lang-sdk-test` — no CI workflow changes needed.
Known tradeoff: this makes the lang-SDK test provisioning require network
access to GitHub, which it
didn't before.
