stewart-r · anna-singleton-resolver · anna-singleton-resolver · web-flow · commit ec359164400e · 2026-02-13T16:34:54.000Z
* feat: openCV resizing * fix: linting and enum for selecting openCV resampling algos * chore: remove irrelevant comment * refactor: imagemagick is no longer a dependency for the functional tests * feat: entirely remove PIL from this project * chore: unify image_generation files into once place * chore: remove defunct file * style: lint * style: standardise opencv2 imports to be import cv2 as cv * doc: remove reference to PIL in docs * chore: capitalisation Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * chore: grammar Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * refactor: split out image_generation file into separate module * feature: add functional end to end tests * fix: fix ruff linting * fix: fix ruff format check * fix: fix type checks * feat: add test cases for live model * test: Improve e2e functional tests for classify_single Better Logging, Enhanced Error Handling, and Updated Expected Outputs * chore: Add VSCode workspace settings for Athena tests * more configuration options for the client (#92) * feat: correlationid can be specified on ImageData * feat: set brotli compression quality * style: lint * fix: fixup example code * feat: configurable resizing algorithm --------- Co-authored-by: anna-singleton-resolver <anna.singleton@resolver.com> * test: add color channel functional test * fix: streaming tests hang - add explicit aclose() to terminate gRPC stream - Call results.aclose() before breaking from response loop to properly terminate the async generator and underlying gRPC stream - Update snapshot for lakeside/pexels-pixabay-210288.jpg (weight 0.9259 -> 0.9215) - Apply same fix to examples/utils for consistency * fix: close stream on error to prevent hanging Add aclose() in exception handlers to ensure the gRPC stream is terminated even when an error occurs during classification. * Fix functional tests: session-scoped auth, skip hanging test, fix color channels * test: reduce default streaming test image count to 50 * test: add integrator sample test set with 10 safe images * refactor: move e2e testcases to athena-protobufs for shared use - Move testcases/ to athena-protobufs submodule - Add .gitattributes for LFS tracking in protobufs - Update parser.py to load from shared location - Remove local testcases (now in submodule) - Fix stale PIL import from rebase conflict * chore: update athena-protobufs with testcases documentation * chore: update athena-protobufs with Pexels license correction * chore: update athena-protobufs with safety clarifications * chore: update athena-protobufs with filename fix * fix: remove missing lakeside images and clean up exclusions list * chore: update athena-protobufs with testcases release workflow * chore: update athena-protobufs with workflow fix * fix: resolve E501 line-too-long linting errors * chore: ruff * fix: remove invalid aclose() calls on AsyncIterator * refactor: clean up EXCLUDED_FILENAMES constant by removing obsolete comment * test: Remove Redundant Assertions.
