🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject an empty platform or empty suffix in artifact_type_to_platform_and_extension.
The check '.' not in remainder accepts malformed values. For example, application/vnd.diskimage..qcow2 returns an empty platform. The value application/vnd.diskimage.qemu. returns an empty extension. Both pass the check. An empty platform then produces a silent mismatch in select_platforms_to_download. An empty extension can produce a bad file name later.
Also, suffix.replace('gzip', 'gz') replaces the text anywhere in the suffix. A suffix such as gzipped becomes gzed. Replace only the final component.
Proposed fix
- if '.' not in remainder:
- raise ValueError(f"Malformed artifactType (missing platform): {artifact_type}")
- platform_name, suffix = remainder.split('.', 1)
- suffix = suffix.replace('gzip', 'gz')
+ platform_name, _, suffix = remainder.partition('.')
+ if not platform_name or not suffix:
+ raise ValueError(f"Malformed artifactType (expected <platform>.<filetype>): {artifact_type}")
+ if suffix.endswith('.gzip'):
+ suffix = suffix[:-len('gzip')] + 'gz'
+ elif suffix == 'gzip':
+ suffix = 'gz'📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Instead of abusing the platform field, switch to the more default `artifactType` field. The value we put in there is still custom to our build pipeline but it won't break any tooling as this field is meant for this type of usage.

235-236: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winFix the remaining
gzipreplacement and the redundant check.The prior review comment flagged the unbounded replace. That is only partly addressed. Line 240 still uses
suffix.replace('gzip', 'gz'). This call replaces the text anywhere in the suffix. A suffix such asgzippedbecomesgzed. Replace only the finalgzipcomponent.The check on Line 235 is also redundant. Line 238 already rejects an empty platform or empty suffix. Line 235 also gives a less accurate error message.
Proposed fix
