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.

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

The program is just a CLI, so rather than releasing to test, you could tweak this command: https://github.com/snok/container-retention-policy/blob/main/justfile#L44 (e.g., set dry-run: true) then call it with just run.

This commit fixes a critical bug where manifest fetching was happening for the wrong set of tags, causing platform-specific images from kept multi-platform tags to be deleted. The Problem: - Code was fetching manifests for tagged versions selected FOR DELETION - This protected digests from tags we planned to delete anyway - Platform-specific images from KEPT multi-platform tags were NOT protected - Result: Multi-platform images broke after retention policy runs The Fix: 1. Fetch ALL package versions (unfiltered) 2. Apply filtering to determine versions TO DELETE 3. Compute inverse set to determine versions TO KEEP 4. Fetch manifests for KEPT versions (not deleted ones) 5. Build digest protection set from kept tags 6. Apply digest protection when processing deletions Changes: - Refactored select_package_versions() to compute kept vs deleted sets - Fetch manifests for tagged_versions_to_keep instead of package_versions_to_delete - Added logging: "Computed X tagged versions to keep, Y to delete" - Added debug logging: "Fetching manifest for kept tag to protect its digests" Testing: - All 33 unit tests pass - All 2 integration tests pass - Code compiles without warnings Documentation: - Created BUG_FIX_MANIFEST_FETCHING.md with detailed analysis - Updated MULTIPLATFORM_FIX_PLAN.md with Issue snok#7 Related to snok#90 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Raw ANSI escape codes (\x1b[34m, \x1b[32m, etc.) were displaying literally in terminal output and GitHub Actions instead of rendering as colors. This was causing output like "\x1b[34mlims-vasa\x1b[0m" instead of colored text. Changes: 1. Removed ANSI codes from progress messages (client.rs:229) - Progress spinner messages now display plain text - Rate limit information shows without color codes 2. Removed ANSI codes from package name formatting (client.rs:344,351) - Tagged package names: "package:tag" instead of colored version - Untagged package names: "package:<untagged>" instead of colored version 3. Removed ANSI codes from log messages (client.rs:560) - Multi-platform manifest logs now use plain text - Structured logging fields provide context instead of inline colors 4. Removed ANSI codes from progress templates (select_package_versions.rs:260,264) - Spinner template displays package name without colors - Fetch status messages use plain text formatting 5. Removed ANSI codes from digest tag strings (select_package_versions.rs:371-373) - Platform-specific tags: "package:tag (platform)" format - Standard tags: "package:tag" format The tracing library handles appropriate coloring based on terminal capabilities and tracing-subscriber configuration, making raw ANSI codes unnecessary and problematic. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Seems to be doing the stuff as we want, but I have an idea that I want your feedback on @sondrelg , currently we only fetch the information about those tags that we know that we want to keep, not all. Then we get a lot of deletions like this: If we collect the information about all tags, it would be easier to say It would help a lot during troubleshooting, and also if a bug occur so image have been deleted by misstake to if we have it. And it doesn't seems like the operations against the container registry to fetch the metadata is that expensive. |
…nced logging
Implements Plan A from FETCH_ALL_TAGS_ANALYSIS.md to improve logging and
troubleshooting capabilities when deleting multi-platform container images.
Changes:
1. Fetch manifests for ALL tags (not just kept ones) - select_package_versions.rs:336-347
- Previously: Only fetched manifests for tags we want to KEEP
- Now: Fetches manifests for ALL tagged versions in the package
- Benefit: Complete visibility into which tags reference which digests
- Impact: More API calls but no GitHub rate limit impact (OCI registry calls)
2. Fix digest_tag overwrite bug - select_package_versions.rs:353,372
- Changed: HashMap<String, String> to HashMap<String, Vec<String>>
- Previously: Only stored ONE tag per digest (would overwrite if multiple tags used same digest)
- Now: Stores ALL tags that reference each digest
- Bug fix: No longer loses information when multiple tags share the same digest
3. Enhanced deletion logging - client.rs:333-380
- Added digest_associations parameter to delete_package_version()
- For untagged versions, now shows which tags they are part of
- Example output:
* Would have deleted sample-package:<untagged> (part of: v1.0.0 linux/amd64, v1.1.0 linux/amd64)
* Would have deleted sample-package:<untagged> (orphaned - not part of any tag)
- Helps distinguish between protected platform-specific images and truly orphaned digests
4. Pass digest associations through deletion pipeline
- Updated select_package_versions() return type to include digest_tag HashMap
- Updated delete_package_versions() to accept and pass digest_associations
- Wrapped digest_associations in Arc for sharing across async tasks
5. Updated logging messages
- Fetching manifest for tag to discover digest associations (more accurate)
- Discovered X platform-specific digest(s) from Y manifest(s) (reflects all tags fetched)
Benefits:
- Complete tag-to-digest mapping for troubleshooting
- Better logging shows exactly which tags reference which digests
- Can identify orphaned digests vs. protected multi-platform images
- Fixes critical bug where digest associations were lost
- Foundation for future validation features (detect conflicts, shared digests, etc.)

Changed so we are collecting information on "tags", still untested to run an actual "deletion", only tried with dry-mode. I think we may have a bug so it's only removing the tag, but then the actual images will get removed on the run after. If you want to try it you can use: |

Fixes critical bug where deleting a multi-platform tag (e.g. v1.0.0) would only delete the tag itself, leaving its platform-specific SHA digests orphaned in the registry. This defeated the purpose of retention policies for multi-platform images and caused storage waste. Root Cause: The code was protecting ALL digests referenced by ANY tag (kept OR deleted). In select_package_versions.rs:433, the filter checked if digest was in the 'digests' HashSet, which contained digests from both kept and deleted tags. Changes: 1. Build tag categorization map (lines 292-354) - Track which tags are kept vs deleted in tag_is_kept HashMap - Enables digest categorization by tag status 2. Separate kept_digests from deleted_digests (lines 372-424) - kept_digests: Digests from tags we want to KEEP (protect from deletion) - deleted_digests: Digests from tags we want to DELETE (include in deletion) - Handle shared digests: kept takes precedence (line 414) - Enhanced logging shows counts for both categories 3. Add deleted tag digests to deletion list (lines 429-438) - Find untagged versions matching deleted_digests - Add them to package_versions.untagged for deletion - Ensures platform-specific images are deleted with their tags 4. Update filtering to only protect kept_digests (lines 440-478) - Changed from 'if digests.contains()' to 'if kept_digests.contains()' - Only protects digests from tags we want to KEEP - Allows deletion of digests from DELETED tags and orphaned digests - Updated debug messages to clarify KEPT vs DELETED 5. Store all_versions alongside deletion candidates (line 369) - Needed to look up untagged versions matching deleted_digests - Updated tuple structure in all_package_data Edge Cases Handled: - Shared digests (same digest used by kept and deleted tags): kept wins - Orphaned digests (not referenced by any tag): deleted if they match filters - Manifest fetch failures: already handled by existing error handling Impact: - Before: Deleting v1.0.0 left 3 orphaned platform digests - After: Deleting v1.0.0 also deletes its 3 platform digests - Logging now accurately shows which digests are from KEPT vs DELETED tags Related to snok#90 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

There was a problem hiding this comment.
The program is just a CLI, so rather than releasing to test, you could tweak this command: https://github.com/snok/container-retention-policy/blob/main/justfile#L44 (e.g., set dry-run: true) then call it with just run.

Hi
My ideas was to keep the md file during review, if you want to get a better
understanding on the reasoning behind the code change and then remove them.
I can make a tag on my fork with them and do some clean up if you want.

Do you want me to review all the markdown files here, or are they
leftovers from testing? I have to admit +2870 is not the most appealing
diff to get started on 😅

Fix multi-platform image support
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.
Important: This PR includes a critical bug fix (commit
1f74a94) that corrects manifest fetching logic to protect digests from tags we want to KEEP (not DELETE).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.
Solution
1. Manifest Fetching and Digest Protection
Critical Fix (commit
1f74a94):Files modified:
src/client/client.rs- Addedfetch_image_manifest()method to retrieve OCI manifests from ghcr.iosrc/core/select_package_versions.rs- Added digest fetching and filtering logic (fixed in commit1f74a94)2. Support for Multiple Manifest Formats
Gracefully handles both manifest types:
application/vnd.oci.image.index.v1+json) - multi-platform imagesapplication/vnd.docker.distribution.manifest.v2+json) - single-platform imagesFiles modified:
src/client/client.rs- Added parsing for both OCI Image Index and Docker Distribution Manifest formatssrc/client/models.rs- Added manifest data structures3. Enhanced Logging
Added detailed logging to help users understand multi-platform image handling:
Files modified:
src/client/client.rs- Added INFO/DEBUG logging for manifest detectionsrc/core/select_package_versions.rs- Added summary logging for protected images and kept/deleted counts4. Owner Handling Refactoring
Simplified owner handling by recognizing that all packages in a single run belong to the same owner:
PackagesClientafter fetching first packageFiles modified:
src/client/client.rs- Addedownerfield, populate from first packagesrc/client/builder.rs- Initialize owner as Nonesrc/core/select_packages.rs- ReturnVec<String>instead ofVec<(String, String)>src/core/select_package_versions.rs- AcceptVec<String>, removed HashMap5. Fix keep-n-most-recent Logic
Corrected the
keep-n-most-recentcalculation to apply after digest filtering, not before. This ensures that protected platform-specific images don't count toward the keep limit.Example:
keep-n-most-recent=5→ Keep 5 from remaining 7, delete 2Files modified:
src/core/select_package_versions.rs- Removed incorrect adjustment logic6. Robust Error Handling
All manifest fetch errors are now non-fatal:
Files modified:
src/client/client.rs- Added error handling for network/HTTP/parsing errors7. Comprehensive Testing
Unit Tests
Added tests for:
Test Results: ✅ All 33 unit tests pass
Files modified:
