Phase 1: Enhance ICalLogic with special character handling - Add quote_special_chars parameter to ICalLogic.generate_object_url() - Implement quote(uid.replace("/", "%2F")) logic from sync version - Add urllib.parse.quote import - Ensures both sync and async use same URL generation with proper escaping - Addresses issue #143 (double-quoting slashes in UIDs) Phase 2: Make DAVObject inherit from DAVObjectCore - Add import for DAVObjectCore from caldav.lib.dav_core - Change class declaration: class DAVObject(DAVObjectCore) - Refactor __init__ to call super().__init__() - Remove duplicated URL initialization code - Update canonical_url property to use parent's get_canonical_url() - Result: Eliminates ~14 lines of duplicated initialization logic Phase 3: Make AsyncDAVObject inherit from DAVObjectCore - Add import for DAVObjectCore from caldav.lib.dav_core - Change class declaration: class AsyncDAVObject(DAVObjectCore) - Refactor __init__ to call super().__init__() - FIX: Replace broken async URL logic with correct implementation - Update canonical_url to use parent's get_canonical_url() - Remove duplicated methods: get_display_name, __str__, __repr__ - Result: Eliminates ~25 lines, FIXES async URL initialization bug Phase 4: Make CalendarObjectResource use ICalLogic - Add import for ICalLogic from caldav.lib.ical_logic - Update _find_id_path: Use ICalLogic.generate_uid() instead of uuid.uuid1() - Update _generate_url: Use ICalLogic.generate_object_url() with special char handling - Ensures sync implementation uses same shared logic as async Impact: - DAVObject: -14 lines (416 lines, was 430) - AsyncDAVObject: -25 lines (209 lines, was 234) - CalendarObjectResource: Uses shared logic for UID/URL generation - ICalLogic: Enhanced with special character handling (89 lines) - DAVObjectCore: Available for both sync/async (108 lines) Benefits: - Eliminates ~40 lines of duplicated code across DAV classes - Fixes async URL initialization to match sync behavior - Ensures sync and async use identical UID/URL generation logic - Single source of truth for core DAV object operations - Special character handling (slashes) properly implemented per issue #143 Bug Fixes: - AsyncDAVObject URL initialization now consistent with DAVObject - Previously async had different/broken URL logic that didn't join with client.url - Now both sync and async use identical URL resolution from DAVObjectCore Testing: - All modified files compile successfully - Import structure verified - Inheritance chains confirmed - ICalLogic special character handling tested Co-authored-by: Claude --- caldav/async_davobject.py | 43 +++++++------------------------- caldav/calendarobjectresource.py | 9 +++++-- caldav/davobject.py | 26 +++++-------------- caldav/lib/ical_logic.py | 17 +++++++++++-- 4 files changed, 37 insertions(+), 58 deletions(-) diff --git a/caldav/async_davobject.py b/caldav/async_davobject.py index 0d0d9b82..5492bfde 100644 --- a/caldav/async_davobject.py +++ b/caldav/async_davobject.py @@ -22,6 +22,7 @@ from .elements import dav from .elements.base import BaseElement from .lib import error +from .lib.dav_core import DAVObjectCore from .lib.python_utilities import to_wire from .lib.url import URL @@ -36,7 +37,7 @@ log = logging.getLogger("caldav") -class AsyncDAVObject: +class AsyncDAVObject(DAVObjectCore): """ Async base class for all DAV objects. @@ -71,33 +72,15 @@ def __init__( props: a dict with known properties for this object id: The resource id (UID for an Event) """ -

The integration of dav_core and ical_logic created "divergent implementations" which is worse than code duplication. Changes: - Deleted caldav/lib/ical_logic.py (added no value, wrong style) - Deleted caldav/lib/dav_core.py (created divergent implementations) - Restored inline implementations in async_collection.py - Reverted davobject.py, async_davobject.py, calendarobjectresource.py Reviewer Concerns Addressed: 1. "Divergent implementations" - Reverted changes that created different code paths for sync vs async 2. ICalLogic module - Removed entirely as requested 3. DAVObjectCore - Removed to eliminate divergence 4. Code maintainability - Restored simpler, more conventional patterns Current State: - async_objects.py consolidation KEPT (good change) - Separate sync/async implementations (parallel approach) - No shared utility modules - Clean, maintainable code matching existing style Next Steps: Will propose RFC for native async + code generation approach as separate v3.0 initiative per reviewer suggestion.
