This commit addresses a critical bug where subtasks would disappear when
updating the parent task (e.g., assigning tags). The issue had multiple
potential causes:
1. Backend vulnerability: The updateSubtasks() function would delete all
subtasks if an empty array was sent, treating it as "delete everything
not in this list"
2. Frontend state management: After reloading a task, subtasks weren't
being preserved if the backend response didn't include them
3. Unclear error messages: "Invalid parent task" errors didn't provide
enough context for debugging
Changes:
- Added defensive logging in updateSubtasks() to warn when all subtasks
are being deleted with an empty array
- Enhanced validateParentTaskAccess() error messages to provide detailed
diagnostics (task not found vs. permission issues vs. wrong user)
- Updated handleTagsUpdate() in TaskDetails to explicitly preserve
subtasks when reloading task after tag updates
This fix is defensive in nature and adds better observability for
diagnosing similar issues in the future.
Fixes issue reported by user where subtasks disappeared after assigning
tags to parent task, and "Invalid parent task" errors occurred when
trying to update the orphaned subtasks.
* Fix Today page task completion issues
- Fix completed task border color staying as priority color
- Add isInCompletedSection prop to TaskItem for explicit completed state
- Tasks in completed section now always show green border regardless of priority
- Fixes race condition where status wasn't updated during optimistic UI update
- Fix completed task reappearing after unmarking and page refresh
- Add defensive check in backend to force clear completed_at when status is not DONE
- Add development logging in tasksService for debugging completion toggle
- Ensures database state is consistent even if handleCompletionStatus doesn't clear it
- Update TaskList and TasksToday components to pass isInCompletedSection prop
- Explicitly marks tasks rendered in the completed section
- Prevents border color flickering during state transitions
* Add comprehensive logging to debug completion issues
* Fix duplicate API requests causing completion state issues
- Separate state update logic from API call in handleTaskUpdate
- Create new updateTaskInState function for state-only updates
- Pass onTaskCompletionToggle to completed section to avoid duplicate calls
- This fixes the persistence issue where unmarked tasks came back after refresh
- Completion toggles now only make ONE API call instead of two
* Add debug logging to updateTaskInState
