From 469fc7cbe280d4e9bf9736d6e9fab6722c6c0dab Mon Sep 17 00:00:00 2001 From: Jamie Pine Date: Tue, 9 Sep 2025 02:03:17 -0400 Subject: [PATCH] refactor: complete migration to modular action system and remove ActionOutput enum - Eliminated the centralized `ActionOutput` enum, achieving true modularity in action handling. - Introduced the `ActionType` trait, allowing each action to define its own output type directly. - Updated multiple actions to utilize native output types, enhancing type safety and reducing complexity. - Enhanced the `ActionManager` with a generic `dispatch_action` method for improved action execution. - Preserved existing infrastructure for validation, audit logging, and error handling throughout the migration. These changes significantly improve the modularity and maintainability of the action system while ensuring a consistent API surface. --- core/src/cqrs.rs | 71 ++-- core/src/infra/action/handler.rs | 38 +-- core/src/infra/action/manager.rs | 59 ++-- core/src/infra/action/mod.rs | 316 ++---------------- core/src/infra/action/output.rs | 100 +----- core/src/infra/action/registry.rs | 1 - .../src/infra/cli/daemon/handlers/location.rs | 10 +- core/src/infra/cli/daemon/types/responses.rs | 4 +- core/src/lib.rs | 22 +- core/src/ops/content/action.rs | 4 +- core/src/ops/devices/revoke/action.rs | 6 +- core/src/ops/files/copy/action.rs | 128 +++---- core/src/ops/files/copy/input.rs | 77 +++-- core/src/ops/files/delete/action.rs | 88 ++++- .../ops/files/duplicate_detection/action.rs | 6 +- core/src/ops/files/validation/action.rs | 6 +- core/src/ops/indexing/action.rs | 6 +- core/src/ops/libraries/create/action.rs | 94 ++---- core/src/ops/libraries/delete/action.rs | 61 ++-- core/src/ops/libraries/export/action.rs | 6 +- core/src/ops/libraries/rename/action.rs | 141 ++++---- core/src/ops/locations/add/action.rs | 191 +++++------ core/src/ops/locations/index/action.rs | 5 +- core/src/ops/locations/remove/action.rs | 7 +- core/src/ops/locations/rescan/action.rs | 6 +- core/src/ops/media/thumbnail/action.rs | 6 +- core/src/ops/metadata/action.rs | 6 +- core/src/ops/volumes/speed_test/action.rs | 71 ++-- core/src/ops/volumes/speed_test/output.rs | 1 + core/src/ops/volumes/track/action.rs | 210 ++++-------- core/src/ops/volumes/track/output.rs | 1 + core/src/ops/volumes/untrack/action.rs | 147 ++++---- core/src/ops/volumes/untrack/output.rs | 1 + crates/job-derive/src/lib.rs | 1 + docs/CQRS_COMPLETE.md | 120 +++++++ docs/CQRS_FINAL_STATUS.md | 123 +++++++ docs/CQRS_SIMPLIFIED.md | 134 ++++++++ docs/IMPLEMENTATION_SUMMARY.md | 138 ++++++++ docs/MIGRATION_CORRECTED.md | 99 ++++++ docs/PERFECT_ACTION_MODEL.md | 105 ++++++ docs/UNIFIED_ACTION_STATUS.md | 141 ++++++++ 41 files changed, 1568 insertions(+), 1189 deletions(-) create mode 100644 docs/CQRS_COMPLETE.md create mode 100644 docs/CQRS_FINAL_STATUS.md create mode 100644 docs/CQRS_SIMPLIFIED.md create mode 100644 docs/IMPLEMENTATION_SUMMARY.md create mode 100644 docs/MIGRATION_CORRECTED.md create mode 100644 docs/PERFECT_ACTION_MODEL.md create mode 100644 docs/UNIFIED_ACTION_STATUS.md diff --git a/core/src/cqrs.rs b/core/src/cqrs.rs index c9cb64212..f015e7a02 100644 --- a/core/src/cqrs.rs +++ b/core/src/cqrs.rs @@ -1,54 +1,43 @@ -//!
