From 649ebf2dc7dc9c4b6f348c61c89b9e9c572a73c9 Mon Sep 17 00:00:00 2001 From: Lukas Date: Wed, 22 Apr 2026 21:30:31 +0200 Subject: [PATCH] fix: preserve zero values in autoSavePayload TASK-BUG-04: The autoSavePayload was using the || operator to fall back to server values when ban_time, find_time, or max_retry were empty or zero. This silently dropped user intent to set these fields to 0, which is a valid and meaningful value in fail2ban (e.g., ban_time=0 means permanent ban). Replace the || fallback with explicit NaN and empty-string guards that only fall back when: 1. The trimmed input is empty (user cleared the field) 2. The input is non-numeric (NaN) This preserves valid zero values while still falling back appropriately for invalid input. - ban_time: 0 now correctly sends permanent ban instead of falling back - find_time: 0 now sends the intended value instead of falling back - max_retry: 0 now sends the intended value instead of falling back Added comprehensive tests for: - Preserving zero values in the payload - Falling back for empty input - Falling back for non-numeric input Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- frontend/src/components/config/JailsTab.tsx | 6 +- .../config/__tests__/JailsTab.test.tsx | 144 ++++++++++++++++++ 2 files changed, 147 insertions(+), 3 deletions(-) diff --git a/frontend/src/components/config/JailsTab.tsx b/frontend/src/components/config/JailsTab.tsx index 7c85c61..1aff34c 100644 --- a/frontend/src/components/config/JailsTab.tsx +++ b/frontend/src/components/config/JailsTab.tsx @@ -210,9 +210,9 @@ function JailConfigDetail({ const autoSavePayload = useMemo( () => ({ - ban_time: Number(banTime) || jail.ban_time, - find_time: Number(findTime) || jail.find_time, - max_retry: Number(maxRetry) || jail.max_retry, + ban_time: banTime.trim() === "" || Number.isNaN(Number(banTime)) ?
