Conversation
…lspec
Add three module-level helpers to pyartcd/pipelines/update_golang.py:
- _parse_pullspec_tuple: normalises both floating-tag and NVR golang-builder
pullspecs to a (major, minor, rhel_version) int-tuple; raises ValueError
for unrecognised formats
- _branch_uses_floating_tags: returns True when any golang-builder stream
entry in streams_content uses the floating-tag format
(golang-builder-v{major}.{minor}-rhel{el})
- _pullspecs_match: compares two pullspecs by tuple when both are parseable;
falls back to string equality for legacy/unrecognised formats
Update _get_builder_pullspec(builder_nvr, streams_content=None) to:
- Auto-read streams from the memoized _branch_content when not passed
explicitly (no extra GitHub fetch; run() already populates the cache)
- Return golang-builder-v{major}.{minor}-rhel{el} when the branch uses
floating tags, falling back to NVR pullspec on parse failure
Replace all five info['image'] == ref string-equality comparisons in
update_golang_streams() with _pullspecs_match()-based equivalents so that
a floating-tag pullspec and an NVR pullspec for the same builder version
are treated as equal. Covers both the minor-bump path (lines ~969-1003)
and the major-bump elif block (lines ~1005-1020). Adds isinstance(info,
dict) guard so non-dict stream entries are skipped gracefully.
Add comprehensive unit tests covering all new code paths including the
cross-format equality case (SC-3), cache auto-read, except fallback,
non-dict/missing-image defensive branches, and major-bump GO_LATEST update.

Guard against non-string image values.
info.get('image', '') returns the stored value when the key exists. A streams.yml entry written as image: with no value loads as None. Line 73 then calls .split on None and raises AttributeError, which aborts the pipeline. Coerce the value to a string before splitting.

Return a full pullspec, not a bare tag.
The bare tag from line 885 fails the full-pullspec check in doozer/doozerlib/image.py. Consumers can then pass it to resolve_brew_image_url, which treats it as a Brew-relative image instead of registry.redhat.io/openshift/golang-builder. Preserve the repository from full_pullspec.
