From 6c7a3e8f634db3e2d0861c1aafa242ceaa0bc686 Mon Sep 17 00:00:00 2001 From: Tobias Brox Date: Sat, 16 May 2026 14:34:54 +0200 Subject: [PATCH 1/4] feat: Calendar.delete() wipe parameter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Also catches the NotFoundError when an event is deleted and ignores the error. For some calendar servers it may be necessary. The wipe parameter is a tristate: True – wipe all objects, keep the calendar (for servers like Nextcloud where HTTP DELETE moves the calendar to a trashbin) False – always issue HTTP DELETE None – existing auto-detect: wipe if the server doesn't support deletion Same applied to the async path (_async_delete). This change was AI-generated. According to the AI policy feature changes should in general be human-made. This change was done en-passant in a long session dealing with improved test coverage in the GitHub CI runs and getting all the tests to pass. I've carefully looked through the changeset and amended it. I couldn't do it better myself (I'm very unhappy about the duplicated code between the async and sync delete, but haven't come up with any good ideas on how to consolidate this yet). The background for this wipe feature was very slow runs on GitHub - Claude claimed it was due to the NextCloud database getting bloated up due to the thrashcan feature in NextCloud. Me (the human) suggested to wipe the calendar instead of deleting it to avoid this thrashcan problem. Since we already have wipe-logic in the library I didn't want it duplicated in the test code, so I suggested to have this wipe-parameter to delete. (It's probably moot anyway, Claude later disabled the thrashcan feature from the NextCloud config - but it's a nice feature to have). Co-Authored-By: claude-sonnet-4-6 refactor: DRY up wipe logic in Calendar.delete() via recursive call The bottom `if wipe:` block in both the sync and async delete paths duplicated the `wipe is True` early-return logic, but without the NotFoundError resilience. Replace both with a recursive call into the wipe=True path. prompt: in caldav/collections.py, in the delete function for calendars, the wipe logic is duplicated. Please make it DRY, for instance through a recursive call Co-Authored-By: Claude Sonnet 4.6 AI Prompts: claude-sonnet-4-6: in caldav/collections.py, in the delete function for calendars, the wipe logic is duplicated.

Care should still be taken, those features are backed by many tests, but lacks testing for how well they support real-world use-case scenarios. While async support was added in version 3.0, it was not well-enough tested. Still only a fraction of all the integration tests for sync usage has been duplicated in the async integration test, I expect to release 3.2.1 with symmetric async integration tests before 2025-07. diff --git a/caldav/calendarobjectresource.py b/caldav/calendarobjectresource.py index 49481a67..e554e333 100644 --- a/caldav/calendarobjectresource.py +++ b/caldav/calendarobjectresource.py @@ -319,8 +319,10 @@ def expand_rrule(self, start: datetime, end: datetime, include_completed: bool = and occurrence.get("STATUS") in ("COMPLETED", "CANCELLED") ): continue - ## TODO: If there are no reports of missing RECURRENCE-ID until 2027, - ## the if-statement below may be deleted + ## RFC 4791 §9.6.5: server-side expansion MAY omit RECURRENCE-ID on the + ## initial instance.

Only GitHub logic is touched in this commit. Nextcloud: - Add email addresses for scheduling test users (user1-user3). Without mailto: entries in calendar-user-address-set, iTIP delivery fails. - Disable CalDAV trashbin (calendarRetentionObligation=0) so that HTTP DELETE hard-deletes objects; without this, recreating the same UID causes a UNIQUE constraint violation (500 Internal Server Error). Cyrus: - Copy imapd.conf with virtdomains: off before starting CalDAV. The default virtdomains: userid causes caladdress_lookup() to retain the full email form as the userid while mailbox ACLs use the short form, resulting in 403 on iTIP invite delivery. - Unpin Cyrus from the March 2026 digest; :latest is stable again. - Health check uses the CalDAV port (8800) now that the management port (8001) is no longer exposed. async-httpx job: - Add Baikal as a service so the httpx-fallback path is tested end-to-end against a real server (previously only unit tests ran for this backend). Rename "async (niquests fallback)" → "async (niquests)" to reflect that niquests is now the default install, not a fallback. Add comment block explaining why the async-* jobs exist separately from the main tests job. This was AI-generated. I'm happy to let Claude deal with the GitHub CI stuff. prompt: fix the github ci failures for scheduling tests followup-prompt: github runs still fail, please investigate (rinse and repeat. Claude had various hypothesis on why things were breaking and was repeatedly doing code changes - so "why do you think those code changes are relevant, after all the tests are passing locally?" was also frequently used.

charset=UTF-8 Content-Transfer-Encoding: 8bit The purpose of the session was to improve test coverage by the GitHub tests. I think all tests run by GitHub is also run locally when I'm running the tests - so I'm a bit confused on why it's needed to change the test code (as opposed to only fix the github CI setup), but I deem the changes to be OK. Most of this commit was done by generative AI. It's deemed OK to use AI for generating and maintaining the test suite. This is the AI-generated description of what was done: Async test generators (ev1, ev2, todo1, todo2) now produce a fresh uuid4 per call. Fixed UIDs caused UNIQUE constraint violations on Nextcloud because deleted objects stay in oc_calendarobjects with a deleted_at timestamp until the trashbin is purged. async_calendar and sibling fixtures are refactored to use stable cal_ids. At teardown, servers where delete-calendar.free-namespace is unsupported (Nextcloud trashbin) now call calendar.delete(wipe=True) instead of HTTP DELETE to keep the trashbin empty and the database fast. The async_task_list sharing-with-Cyrus workaround is removed — wipe-at-teardown guarantees UIDs are gone before the sync suite runs. test_object_by_uid generates a random UID and deletes it at the end so repeated runs don't collide. testRecurringDateWithExceptionSearch: fall back to DTSTART when RECURRENCE-ID is absent (RFC 4791 §9.6.5 permits servers to omit it on the initial expanded instance). Sync _cleanup: add missing return after wipe-calendar branch so the cleanup does not fall through to cal.delete() and delete the calendar anyway. _fixCalendar: give VJOURNAL-only calendars a distinct cal_id ("-journals") so they don't collide with VTODO-only calendars ("-tasks") under the wipe-calendar regime where calendars persist across tests. Unify wipe logic: the three manual wipe loops in _cleanup/_fixCalendar are replaced with cal.delete(wipe=True), which now lives only in collection.py. test_servers: register Baikal URL_ENV_VAR so the async-httpx CI job can reach it; add get_available_servers() helper used by async integration tests. prompt: (most of it on the form "github runs still fail — please check why", though apparently I've asked it to delete calendar content rather than deleting the full calendar) Co-Authored-By: claude-sonnet-4-6 --- tests/test_async_integration.py | 164 +++++++++++++++++++++----------- tests/test_caldav.py | 68 ++++++------- tests/test_servers/base.py | 34 +++---- tests/test_servers/registry.py | 9 +- 4 files changed, 166 insertions(+), 109 deletions(-) diff --git a/tests/test_async_integration.py b/tests/test_async_integration.py index fcedc0d3..f17ca163 100644 --- a/tests/test_async_integration.py +++ b/tests/test_async_integration.py @@ -8,6 +8,7 @@ """ import asyncio +import uuid from datetime import datetime, timedelta, timezone from functools import wraps from typing import Any @@ -95,7 +96,7 @@ def make_todo(uid: str, summary: str, status: str = "NEEDS-ACTION") -> str: def ev1() -> str: base = _get_base_date() return make_event( - "async-test-event-001@example.com", + f"async-test-event-001-{uuid.uuid4()}@example.com", "Async Test Event", base, base + timedelta(hours=11), @@ -105,7 +106,7 @@ def ev1() -> str: def ev2() -> str: base = _get_base_date() return make_event( - "async-test-event-002@example.com", + f"async-test-event-002-{uuid.uuid4()}@example.com", "Second Async Test Event", base + timedelta(days=1), base + timedelta(days=1, hours=11), @@ -113,11 +114,13 @@ def ev2() -> str: def todo1() -> str: - return make_todo("async-test-todo-001@example.com", "Async Test Todo") + return make_todo(f"async-test-todo-001-{uuid.uuid4()}@example.com", "Async Test Todo") def todo2() -> str: - return make_todo("async-test-todo-002@example.com", "Completed Async Todo", "COMPLETED") + return make_todo( + f"async-test-todo-002-{uuid.uuid4()}@example.com", "Completed Async Todo", "COMPLETED" + ) async def add_event(calendar: Any, data: str) -> Any: @@ -221,80 +224,85 @@ async def async_principal(self, async_client: Any) -> Any: @pytest_asyncio.fixture async def async_calendar(self, async_client: Any) -> Any: - """Create a test calendar or use an existing one if creation not supported.""" + """Create or find a stable test calendar, wiping it before and after use. + + Uses a stable cal_id so the calendar is reused across tests.
