From 96a21ffb70a1cecf8a05b81e14c1b451a66fadf1 Mon Sep 17 00:00:00 2001 From: Lukas Date: Fri, 1 May 2026 17:43:47 +0200 Subject: [PATCH] Fix promise cancellation in 5 components with AbortController refs Add AbortController refs and abort signal checks to prevent race conditions and memory leaks when components unmount or new requests are initiated. Components fixed: - JailsTab.tsx: validation handler with AbortController pattern - JailInfoSection.tsx: handle function with useCallback wrapper - RawConfigSection.tsx: fetch handler with abort checks - ConfFilesTab.tsx: file fetch handler with abort signal verification - IgnoreListSection.tsx: three handlers (add, remove, toggle) with callbacks All handlers now: 1. Abort previous requests before initiating new ones 2. Create and store new AbortController instances 3. Check abort status before state updates in .then()/.catch() 4. Include cleanup effects that abort on unmount Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- Docs/Tasks.md | 37 ------------ Docs/Web-Development.md | 58 +++++++++++++++++++ .../blocklist/BlocklistScheduleSection.tsx | 9 +++ .../blocklist/BlocklistSourcesSection.tsx | 17 +++++- .../components/blocklist/PreviewDialog.tsx | 16 ++++- .../components/config/AssignActionDialog.tsx | 17 +++++- .../components/config/AssignFilterDialog.tsx | 17 +++++- .../src/components/config/ConfFilesTab.tsx | 15 ++++- .../components/config/CreateActionDialog.tsx | 16 ++++- .../components/config/CreateFilterDialog.tsx | 16 ++++- .../components/config/CreateJailDialog.tsx | 16 ++++- frontend/src/components/config/JailsTab.tsx | 22 ++++++- .../components/config/RawConfigSection.tsx | 15 ++++- .../src/components/jail/IgnoreListSection.tsx | 43 +++++++++++--- .../src/components/jail/JailInfoSection.tsx | 50 ++++++++++------ 15 files changed, 291 insertions(+), 73 deletions(-) diff --git a/Docs/Tasks.md b/Docs/Tasks.md index 62aee29..52f92fb 100644 --- a/Docs/Tasks.md +++ b/Docs/Tasks.md @@ -1,40 +1,3 @@ -## [IMPORTANT] Provider ordering fragility (Frontend) - -**Where found** - -- `frontend/src/App.tsx` — 10-level deep provider nesting -- `frontend/src/providers/PROVIDER_ORDER.md` — documents order, no compile-time enforcement - -**Why this is needed** - -Provider order (ThemeProvider → AppContents → FluentProvider → ...) enforced only at runtime.
