Seems like we're not actually targetting the tags we wanted, because the cut-off is set higher than the refresh rate of the workflow. All deletions are handled by the time all images have been replaced, i.e., 10 images are deleted by the first step, and no packages are deleted by the subsequent steps: 2025-01-07T06:34:40.802352Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332129593 2025-01-07T06:34:40.815403Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332117991 2025-01-07T06:34:40.835704Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332129711 2025-01-07T06:34:40.836355Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332118081 2025-01-07T06:34:40.838612Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332129673 2025-01-07T06:34:40.838826Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332118049 2025-01-07T06:34:40.842146Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332118031 2025-01-07T06:34:40.857171Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332129747 2025-01-07T06:34:40.866253Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332118016 2025-01-07T06:34:40.877685Z INFO container_retention_policy::client::client: Deleted container-retention-policy:<untagged> package_version_id=332129625
The .20 patch breaks colored output, so we'll stay on 19 for the time being. We don't log user inputs AFAICT, so we shouldn't be affected.
We didn't tag all image versions in the release, and we reused some of the same tags for the parent. Hoping this will let us build v3.0.1 without breaking v3.0.0
This commit addresses Issue snok#1 from the multi-platform image support plan, fixing the hardcoded package name in the OCI manifest fetch implementation. Changes: 1. Added Owner struct to Package model (models.rs:33-36) - Captures owner.login from GitHub Package API response - Updated Package struct to include owner field 2. Updated PackagesClient to store Account (client.rs:15,32) - Added Account import and field to track account type 3. Updated PackagesClientBuilder (builder.rs:19-84,147-171) - Added account field to builder - Modified generate_urls to store account - Updated build method to require account field 4. Updated select_packages flow (select_packages.rs:13-62) - Changed filter_by_matchers to return Vec<(String, String)> - Returns tuples of (package_name, owner_login) - Updated all tests to include owner information 5. Updated select_package_versions flow (select_package_versions.rs:238-317) - Changed signature to accept Vec<(String, String)> - Created package_owners HashMap for owner lookup - Updated manifest fetching to pass owner parameter 6. Fixed fetch_image_manifest method (client.rs:484-519) - Added owner parameter to method signature - Constructs URL dynamically: ghcr.io/v2/{owner}%2F{package_name}/manifests/{tag} - Properly URL-encodes the package path 7. Fixed missing imports - Added eyre! macro import to select_package_versions.rs - Added info! macro import to main.rs Result: The manifest URL is now dynamically constructed using the owner from the GitHub Package API response, supporting multiple owners across different users and organizations. Resolves part of snok#90
…t types This commit addresses Issue snok#2 from the multi-platform image support plan, improving manifest fetching to handle both OCI Image Index and Docker Distribution Manifest formats gracefully. Changes: 1. Updated fetch_image_manifest parsing logic (client.rs:501-536) - Try parsing as OCI Image Index first (multi-platform images) - If that fails, try Docker Distribution Manifest (single-platform) - If both fail, log warning and return empty vec - No longer fails entire operation on parse errors 2. Added logging for manifest types (client.rs:503-507,521-525,531-535) - Debug log when multi-platform manifest is detected - Debug log when single-platform manifest is detected - Warning log for unknown manifest formats 3. Added warn macro import (client.rs:11) - Imported warn from tracing for warning logs 4. Fixed unused variable warnings (select_package_versions.rs:258,301) - Prefixed unused owner variable with underscore - Removed unnecessary mut from package_versions Result: The manifest fetching now handles both multi-platform and single-platform images correctly, with graceful degradation for unknown formats. Code compiles without warnings. Related to snok#90
Updated the Enhanced Logging section (Issue snok#3) to provide better guidance for implementation and improved user experience. Changes: 1. Updated desired output example (lines 170-183) - Added "(truncated)" to digest display for better readability - Added summary INFO log showing total protected images - Shows comprehensive logging flow from fetch to summary 2. Enhanced implementation guidance (lines 185-189) - Added note to use truncated digests in logs - Added requirement for summary log after processing - Clarifies all logging touchpoints 3. Improved code example (lines 195-227) - Added clarifying comment about single-platform return value - Added tracking for total_protected counter - Added summary log implementation with counts - Shows complete implementation pattern These improvements will help ensure the logging provides clear, actionable information to users while maintaining readability. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

…mages This commit addresses Issue snok#3 from the multi-platform image support plan, adding comprehensive logging to show platform details and which images are being protected from deletion. Changes: 1. Updated Platform struct (client.rs:585-591) - Added optional variant field to support platforms like linux/arm/v7 2. Enhanced fetch_image_manifest logging (client.rs:514-543) - Changed return type to Vec<(String, Option<String>)> to include platform info - Added INFO log when multi-platform manifest is found - Logs each platform with Docker-style short digest (12 hex chars) - Example: "- linux/amd64: abc123def456" - Handles platform variant (e.g., linux/arm/v7) 3. Updated digest processing (select_package_versions.rs:320-348) - Modified to handle tuples of (digest, platform) - Stores platform info in digest_tag HashMap with color coding - Tracks total_protected and manifest_count for summary logging 4. Enhanced SHA skipping logs (select_package_versions.rs:357-373) - Truncates digests to Docker-style format (12 hex chars, no sha256: prefix) - Shows which tag and platform the digest is associated with - Example: "Skipping deletion of abc123def456 because it's associated with package:v1.0.0 (linux/amd64)" 5. Added summary logging (select_package_versions.rs:346-348) - Shows total protected images and manifest count - Example: "Protected 15 platform-specific image(s) from 5 multi-platform manifest(s)" Result: Users now have clear visibility into: - Which manifests are multi-platform vs single-platform - Platform details (OS/architecture/variant) for each digest - Which SHAs are being preserved and why (with Docker-style short digests) - Summary of total protected images Related to snok#90
All packages in a single retention policy run belong to the same owner, so passing owner per-package was unnecessarily complex. Changes: 1. Added owner field to PackagesClient (client.rs:33, builder.rs:171) - Initialized as None in builder - Populated from first package in fetch_packages (client.rs:60-63) 2. Simplified select_packages (select_packages.rs:13-40) - Changed filter_by_matchers to return Vec<String> instead of Vec<(String, String)> - Updated return type from tuples to just package names - Updated all tests to expect Vec<String> 3. Simplified select_package_versions (select_package_versions.rs:239-310) - Changed parameter from Vec<(String, String)> to Vec<String> - Removed package_owners HashMap construction and lookup - Removed unused eyre import 4. Updated fetch_image_manifest (client.rs:492-502) - Removed owner parameter from signature - Uses self.owner instead of passed parameter - Updated manifest fetch calls to not pass owner Benefits: - Simpler code: no tuples, no HashMap lookup - Better performance: less memory allocation - Clearer intent: owner is property of client, not each package - Single source of truth for owner information Result: Code compiles successfully without warnings. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
This commit addresses Issue snok#4 from the multi-platform image support plan, fixing the keep-n-most-recent calculation to work correctly with digest filtering. Problem: The previous implementation used an "adjustment" calculation that tried to compensate for packages filtered out by digest matching. This was incorrect - when tags are filtered because their digests match protected multi-platform images, they should NOT count toward keep-n-most-recent. Example scenario: - 10 tagged package versions initially - User sets keep-n-most-recent=5 - 3 are filtered out (digests match protected multi-platform images) - Expected: Keep 5 most recent from remaining 7 → Delete 2 - Previous (wrong): Adjusted to keep 2 → Delete 5 Changes: 1. Removed incorrect adjustment logic (select_package_versions.rs:385-390) - Deleted adjusted_keep_n_most_recent calculation - Now passes keep_n_most_recent directly to handle_keep_n_most_recent - No adjustment for digest-filtered packages 2. Removed unused variable (select_package_versions.rs:367) - Removed count_before variable (only used for adjustment) 3. Updated plan document (MULTIPLATFORM_FIX_PLAN.md) - Marked Issue snok#4 as completed - Added implementation summary - Updated progress tracking Result: keep-n-most-recent now correctly applies to the remaining packages AFTER digest filtering, matching the expected behavior.

This commit addresses Issue snok#5 from the multi-platform image support plan, improving error handling to ensure the retention policy operation continues even when individual manifest fetches fail. Problem: Previously, any network error, 404, or auth error when fetching manifests would propagate up and fail the entire retention policy run. This was too fragile - a single unavailable manifest shouldn't halt the entire operation. Solution: All manifest fetch errors are now treated as non-fatal and handled gracefully. Failed manifest fetches are treated as single-platform images (no child digests to protect), allowing the operation to continue for other packages. Changes: 1. Added error handling for network failures (client.rs:505-515) - Wrapped .send().await in a match statement - Logs warning with error details on failure - Returns Ok((package_name, tag, vec![])) instead of Err() - Treats failed fetch as single-platform image 2. Added HTTP status code checking (client.rs:517-527) - Checks response.status().is_success() before processing - Handles 404 Not Found, 401 Unauthorized, 403 Forbidden, etc. - Logs warning with HTTP status code - Returns empty vec (single-platform) instead of failing 3. Added error handling for response body reading (client.rs:529-539) - Wrapped .text().await in a match statement - Handles errors reading response body - Logs warning and returns empty vec Error handling strategy: - Operation continues for other packages - Failed manifests treated as single-platform (no child digests) - Clear warning logs help users diagnose issues - Retention policy run completes even if some manifests unavailable Cases already handled: - Single-platform manifests: Already logged with debug level - Unknown manifest formats: Already logged with warning level Result: Manifest fetching is now robust and won't fail the entire retention policy run due to individual manifest fetch failures. Related to snok#90
Added detailed testing section (Issue #6B) for real-world validation against GitHub Container Registry with multi-platform images. Changes: 1. Split testing into two parts: - Issue #6A: Unit tests (optional, for code coverage) - Issue #6B: Integration testing with dry run (CRITICAL) 2. Added comprehensive test scenarios: - Multi-platform image protection test - Old untagged images cleanup test - Keep-n-most-recent with multi-platform test - Logging verification test 3. Defined test execution plan: - Build binary - Set up test environment with PAT (read:packages permission) - Run each scenario and verify output - Document results 4. Specified success criteria: - Platform-specific images from tagged manifests not deleted - Truly orphaned untagged images ARE deleted - keep-n-most-recent correctly calculated - Logging shows platform information - Graceful error handling 5. Updated implementation order and progress tracking: - Reflects refactoring completion - Highlights integration testing as critical next step - Marks unit tests as optional This will allow validation of the multi-platform fix with real GitHub packages before merging to main. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
This commit addresses Issue #6A from the multi-platform image support plan,
adding unit tests to verify correct parsing of different manifest formats.
Tests added:
1. Manifest parsing tests (6 tests) - client.rs:869-1034
- test_parse_multiplatform_manifest
* Tests OCI Image Index with multiple platforms (amd64, arm64, arm/v7)
* Verifies digests are extracted correctly
* Verifies platform info (architecture, OS, variant) is captured
- test_parse_singleplatform_oci_manifest
* Tests OCI Image Index with empty manifests array
* Verifies returns empty vec for single-platform images
- test_parse_singleplatform_oci_manifest_no_manifests_field
* Tests OCI Image Index with no manifests field (None)
* Verifies graceful handling of missing field
- test_parse_docker_distribution_manifest
* Tests Docker Distribution Manifest (single-platform format)
* Verifies config and layers are parsed correctly
- test_parse_invalid_manifest
* Tests handling of invalid JSON
* Verifies both parsers correctly reject malformed JSON
- test_parse_unknown_manifest_format
* Tests handling of valid JSON but unknown format
* Verifies OCI parser is flexible (accepts with no manifests)
* Verifies Docker parser is strict (rejects unknown formats)
Test coverage notes:
Digest filtering and keep-n-most-recent integration tests would require
mocking the HTTP client and async manifest fetching, which is complex for
unit tests. The digest filtering logic is covered by:
- Manual testing with real multi-platform images
- The manifest parsing tests ensure correct parsing
- Existing keep-n-most-recent tests cover that functionality
Test results:
- All 33 tests pass (6 new + 27 existing)
- No test failures
- Tests run in 0.01s
Files modified:
- src/client/client.rs - Added 6 manifest parsing tests
- MULTIPLATFORM_FIX_PLAN.md - Updated with test implementation details

PR mostly generated by claude code but I have tried to understand the code, and giving it good instructions. Some details are in the MULTIPLATFORM_FIX_PLAN.md and details about how I have tested it against my fork with some packages at: INTEGRATION_TEST_RESULTS.md. I plan to test it more against some more repos on monday.
Fixes #90
Summary
This PR adds support for multi-platform container images by detecting and protecting platform-specific images that are part of tagged multi-platform manifests. Previously, the retention policy would incorrectly delete untagged platform-specific images (e.g., linux/amd64, linux/arm64) that were actually referenced by tagged multi-platform manifest lists, breaking the multi-platform images.
Problem
Multi-platform Docker images consist of:
myimage:v1.0.0)When the retention policy processed packages by SHA, it would see platform-specific images as untagged and delete them, even though they were part of a tagged multi-platform image. This broke multi-platform images and caused pull failures.
