From 41f554859364755054f3625b3f571c996186c2c1 Mon Sep 17 00:00:00 2001 From: DanS Date: Sun, 5 Jul 2026 15:08:43 -0500 Subject: [PATCH] fix(ui): prevent stuck spinners and double-submits in dialogs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Address a cluster of low-severity robustness nits where an async callback could be skipped (leaving a spinner spinning forever) or a synchronous action could be re-fired mid-flight: - app_network: add catch(...) fallbacks around the importPrivateKey and submitZSendMany worker lambdas so a non-std throw can't escape the worker and skip the main-thread callback (stuck "Importing…"/"Sending…"). - export_transactions: re-entrancy guard disabling Export while a write is in flight. - bootstrap_download: disable Cancel once clicked so the request is visibly acknowledged and can't be re-fired before the worker stops. - network_tab: give clear "already in list" feedback on a duplicate server (keep the inputs, clear only the stale invalid-URL error) and disable/relabel Refresh while a probe is in flight. - key_export: offer Retry from the error branch (falls back to Reveal) and guard against an empty/malformed address before dispatching. - receive_tab: only enter the "generating…" state when a dispatch is actually possible (guards a stuck spinner when disconnected).
