- Update CacheRequest test to use version field
- Fix upload_test_file calls that still used tag parameter
- Update artifact history test to check versions instead of tags
- Update artifact stats tests to check versions instead of tags
- Fix garbage collection tests to delete versions instead of tags
- Remove TestGlobalTags class (endpoint removed)
- Update project/package stats tests to check version_count
- Fix upload_test_file fixture in test_download_verification
- Remove Tag/TagHistory model tests from unit tests
- Update CacheSettings tests to remove allow_public_internet field

- Remove tests for tag: prefix downloads (now uses version:)
- Update dependency tests for version-only schema
Tags were mutable aliases that caused confusion alongside the immutable
version system. This removes tags entirely, keeping only PackageVersion
for artifact references.
Changes:
- Remove tags and tag_history tables (migration 012)
- Remove Tag model, TagRepository, and 6 tag API endpoints
- Update cache system to create versions instead of tags
- Update frontend to display versions instead of tags
- Remove tag-related schemas and types
- Update artifact cleanup service for version-based ref_count
The circular dependency error '_pypi/psutil → _pypi/psutil' occurred because
dependencies with extras like 'psutil[test]' weren't being recognized as
self-dependencies. The comparison 'psutil[test] != psutil' failed.
- Add _normalize_pypi_package_name() helper that strips extras brackets
and normalizes separators per PEP 503
- Update _detect_package_cycle to use normalized names for cycle detection
- Update check_circular_dependencies to use normalized initial path
- Simplify self-dependency check in resolve_dependencies to use helper
- Add artifact: prefix handling in resolve_dependencies for direct artifact
ID references, enabling dependency resolution for tagless artifacts
- Refactor PackagePage from tag-based to artifact-based data display
- Add PackageArtifact type with tags array for artifact-centric API responses
- Update download URLs to use artifact:ID prefix when no tags exist
- Conditionally show "View Ensure File" only when artifact has tags
- Add _parse_upstream_error() to extract policy messages from JFrog/Artifactory
- Pass through 403 and other 4xx errors with detailed messages
- Pin babel and electron-to-chromium to older versions for CI compatibility
- Add artifact-level self-dependency check (skip if dep resolves to same artifact)
- Close dependency graph modal if package has no dependencies to show
(only root package with no children and no missing deps)
PyPI packages can have self-referential dependencies for extras
(e.g., pytest[testing] depends on pytest). These were incorrectly
detected as circular dependencies. Now we skip them.
When dependencies are not cached on the server (common since we removed
proactive caching), the dependency graph now:
- Continues resolving what it can find
- Shows missing dependencies in a separate section with amber styling
- Displays the constraint and which package required them
- Updates the header stats to show "X cached • Y not cached"
This provides a better user experience than showing an error when
some dependencies haven't been downloaded yet.
When a dependency has an invalid version constraint like '>=' (without
a version number), the resolver now treats it as a wildcard and returns
the latest available version instead of failing with 'Dependency not found'.
This handles malformed metadata that may have been stored from PyPI packages.
The background task queue for proactively caching package dependencies was
causing server instability and unnecessary growth. The PyPI proxy now only
caches packages on-demand when users request them.
Removed:
- PyPI cache worker (background task queue and worker pool)
- PyPICacheTask model and related database schema
- Cache management API endpoints (/pypi/cache/*)
- Background Jobs admin dashboard
- Dependency extraction and queueing logic
Kept:
- On-demand package caching (still works when users request packages)
- Async httpx for non-blocking downloads (prevents health check failures)
- URL-based cache lookups for deduplication
The pypi_download_file, pypi_simple_index, and pypi_package_versions endpoints
were using synchronous httpx.Client inside async functions. When upstream PyPI
servers respond slowly, this blocked the entire FastAPI event loop, preventing
health checks from responding. Kubernetes would then kill the pod after the
liveness probe timed out.
Changes:
- httpx.Client → httpx.AsyncClient
- client.get() → await client.get()
- response.iter_bytes() → response.aiter_bytes()
This ensures the event loop remains responsive during slow upstream downloads,
allowing health checks to succeed even when downloads take 20+ seconds.

- Auto-refreshes every 5 seconds with existing data
When the cache worker downloaded a package through the proxy, dependencies
were always queued with depth=0 instead of depth+1. This meant depth limits
weren't properly enforced for nested dependencies.
Changes:
- Add cache-depth query parameter to pypi_download_file endpoint
- Worker now passes its current depth when fetching packages
- Dependencies are queued at cache_depth+1 instead of hardcoded 0
- Add tests for depth tracking behavior
Replace unbounded thread spawning with managed worker pool:
- New pypi_cache_tasks table tracks caching jobs
- Thread pool with 5 workers (configurable via ORCHARD_PYPI_CACHE_WORKERS)
- Automatic retries with exponential backoff (30s, 60s, then fail)
- Deduplication to prevent duplicate caching attempts
New API endpoints for visibility and control:
- GET /pypi/cache/status - queue health summary
- GET /pypi/cache/failed - list failed tasks with errors
- POST /pypi/cache/retry/{package} - retry single package
- POST /pypi/cache/retry-all - retry all failed packages
This fixes silent failures in background dependency caching where
packages would fail to cache without any tracking or retry mechanism.
When background threads fetch from our own proxy using the request's
base_url, it returns http:// but ingress requires https://. The 308
redirect was dropping trailing slashes, causing requests to hit the
frontend catch-all route instead of /pypi/simple/.
Force HTTPS explicitly in the background caching function to avoid
the redirect entirely.
PEP 503 normalizes package names to use hyphens, but wheel filenames
may use underscores (e.g., typing_extensions-4.0.0-py3-none-any.whl).
Convert the search pattern to match either separator.
The background dependency caching was getting 308 redirects because
request.base_url returns http:// but the ingress redirects to https://.
Enable follow_redirects=True in httpx client to handle this.
When a PyPI package is cached, its dependencies are now automatically
fetched in background threads. This ensures the entire dependency tree
is cached even if pip already has some packages installed locally.
Features:
- Background threads fetch each dependency without blocking the response
- Uses our own proxy endpoint to cache, which recursively caches transitive deps
- Max depth of 10 to prevent infinite loops
- Daemon threads so they don't block process shutdown
- Deduplicate dependencies by package name before inserting
- Some packages (like anyio) list the same dep (trio) multiple times with
different version constraints for different extras
- The unique constraint on (artifact_id, project, package) rejected these
- Also removed debug logging from dependencies.py
- Parse version constraints like >=1.9, <2.0 using packaging library
- Find the latest version that satisfies the constraint
- Support wildcard (*) to get latest version
- Fall back to exact version and tag matching
- Add functions to parse Requires-Dist metadata from wheel and sdist files
- Store extracted dependencies in artifact_dependencies table
- Fix streaming response for cached artifacts (proper tuple unpacking)
- Fix version uniqueness check to use version string instead of artifact_id
- Skip creating versions for .metadata files
- Fix artifact_count and total_size calculation to use Tags instead of
Uploads, so PyPI cached packages show their stats correctly
- Fix PackagePage dropdown menu positioning (use fixed position with backdrop)
- Add system project detection for projects starting with "_"
- Show Version as primary column for system projects, hide Tag column
- Hide upload button for system projects (they're cache-only)
- Rename section header to "Versions" for system projects
- Fix test_projects_sort_by_name to exclude system projects from sort comparison
PyPI proxy improvements:
- Set package format to "pypi" instead of "generic"
- Extract version from filename and create PackageVersion record
- Support .whl, .tar.gz, and .zip filename formats
Package page UX overhaul:
- Move upload to header button with modal
- Simplify table: combine Tag/Version, remove Type and Artifact ID columns
- Add row action menu (⋯) with: Copy ID, Ensure File, Create Tag, Dependencies
- Remove cluttered "Download by Artifact ID" and "Create/Update Tag" sections
- Add modals for upload and create tag actions
- Cleaner, more scannable table layout
- Use storage.get_stream(s3_key) instead of non-existent get_artifact_stream()
- Make _pypi project public (is_public=True) so cached packages are visible
Use correct Artifact model fields:
- original_name instead of filename
- Add required created_by and s3_key fields
- Include checksum fields from storage result
The code was calling storage.store_artifact() which doesn't exist.
Changed to use storage.store() which handles content-addressable
storage with automatic deduplication.
Users can now configure the full path including /simple in their
upstream source URL (e.g., https://example.com/api/pypi/repo/simple)
instead of having the code append /simple/ automatically.
This matches pip's --index-url format, making configuration more
intuitive and copy/paste friendly.
The test was checking for the wrong URL pattern. When urljoin resolves
../../packages/ab/cd/... relative to /api/pypi/pypi-remote/simple/requests/,
it correctly produces /api/pypi/pypi-remote/packages/ab/cd/... (not
/api/pypi/packages/...).
Tests now verify the correct response for each scenario:
- 200: HTML content-type
- 404: "not found" error message
- 503: "No PyPI upstream sources configured" error message
- Tests now accept 200/404/503 responses since upstream sources may or
may not be configured in the test environment
- Added upstream_base_url parameter to _rewrite_package_links test
- Added test for relative URL resolution (Artifactory-style URLs)
When behind a reverse proxy that terminates SSL, the server sees HTTP
requests internally. Added _get_base_url() helper that respects the
X-Forwarded-Proto header to generate correct external HTTPS URLs.
This fixes links in the PyPI simple index showing http:// instead of
https:// when accessed via HTTPS through a load balancer.
Artifactory and other registries may return relative URLs in their
Simple API responses (e.g., ../../packages/...). The proxy now resolves
these to absolute URLs using urljoin() before encoding them in the
upstream parameter.
This fixes package downloads failing when the upstream registry uses
relative URLs in its package index.
