go-mod-vcs.bbclass: handle pure hybrid mode gracefully

2026-03-26T17:55:14+00:00

When a recipe uses only gomod:// fetches with no VCS (git://) modules, GO_MODULE_CACHE_DATA is an empty list. Previously do_create_module_cache would run with nothing to process and do_sync_go_files would fatal with "No modules found in cache". Detect the empty module list and return early with an informational message in both tasks, allowing pure hybrid recipes (like yq) to build without workarounds. Signed-off-by: Bruce Ashfield

go-mod-vcs: fix do_rm_work permission failure on module cache

2026-02-09T05:07:01+00:00

go build creates read-only files in the module cache during do_compile. The previous do_fix_go_mod_permissions task ran before do_compile, so it could not catch these files, causing do_rm_work to fail with permission errors. Replace the standalone task with a do_compile postfunc that fixes module cache permissions after compilation finishes. This covers all go-mod-vcs recipes regardless of how they invoke go build.

go-mod: introduce hybrid mode

2025-12-09T01:57:44+00:00

Introduce the ability to have hybrid gomod:// and git:// repositories. This allows SRCREV bumping when fixing bugs, and using the git archiver for some, all or none of the modules in a go mod project. Example: k3s Hybrid Conversion 1. Ensure VCS mode works first bitbake k3s 2. Get recommendations bitbake k3s -c go_mod_recommend 3. Convert with recommended prefixes (keep containerd, k8s.io as git://) python3 ./meta-virtualization/scripts/oe-go-mod-fetcher-hybrid.py \ --recipedir ./meta-virtualization/recipes-containers/k3s/ \ --git "github.com/containerd,k8s.io,sigs.k8s.io,github.com/rancher" Signed-off-by: Bruce Ashfield

go-mod: make extracted files writeable

2025-12-09T01:57:44+00:00

Make extracted files writable so BitBake can clean them later Go's module cache is read-only by design, but this breaks rm -rf and our subsquent task runs will fail. Signed-off-by: Bruce Ashfield

go-mod-vcs: declare cache defaults

2025-12-09T01:57:44+00:00

There are variables which are common to all recipes, declare defaults to make recipe integration simpler. Also, when creating the cache the messages are normal about synthesis, etc, so reduce them to bb.note. Signed-off-by: Bruce Ashfield

go-mod-vcs: missing go.mod is not a warning

discover: manage go.* files

2025-12-09T01:57:44+00:00

The discovery repository can be in an incosistent state after a build. By restoring the go.* files, we ensure a stable start point. Add automatic removal of go.sum files from git-fetched dependencies in vcs_cache during do_create_module_cache. This prevents checksum mismatch errors caused by stale go.sum files in dependencies having different checksums than the git-sourced modules. Signed-off-by: Bruce Ashfield

classes: add go-mod-vcs and go-mod-discovery for Go module builds

2025-12-09T01:57:44+00:00

Add two new bbclass files that enable building Go applications using git-based module resolution instead of network proxy fetches: go-mod-vcs.bbclass: - Provides do_create_module_cache task to build GOMODCACHE from git sources - Implements pure Python h1: hash calculation with go-dirhash-native fallback - Creates properly structured module zip files and hash files - Handles module path transformations and case encoding go-mod-discovery.bbclass: - Runs module discovery using the oe-go-mod-fetcher tool - Generates go-mod-git.inc and go-mod-cache.inc files - Supports bootstrap mode for initial recipe conversion Together these classes enable fully offline, reproducible Go builds by fetching module sources via git and constructing the module cache during the build rather than relying on network access to module proxies.
