From 195cdf88f15dc4b56d307e1995962102f9aeba36 Mon Sep 17 00:00:00 2001 From: Liu Jinchang Date: Tue, 12 May 2026 10:34:03 +0800 Subject: [PATCH] fix(installer): add partition device existence check to handle physical USB removal MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add QFile::exists() check for partition device in QtBaseInstaller::checkError() before disk lookup to handle physical USB removal gracefully 修复(installer): 增加分区设备存在性检查以处理 USB 物理拔出场景 - 在 QtBaseInstaller::checkError() 中调用磁盘查找前增加 QFile::exists() 检查分区设备是否存在，优雅处理 USB 被物理拔出的情况 Log: 在安装器错误检查流程中增加分区设备存在性检查，防止 USB 被物理拔出后继续执行导致异常 Bug: https://pms.uniontech.com/bug-view-354921.html --- src/libdbm/installer/qtbaseinstaller.cpp | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/libdbm/installer/qtbaseinstaller.cpp b/src/libdbm/installer/qtbaseinstaller.cpp index bc9ea0bd..6a7dffbd 100644 --- a/src/libdbm/installer/qtbaseinstaller.cpp +++ b/src/libdbm/installer/qtbaseinstaller.cpp @@ -1,4 +1,4 @@ -// SPDX-FileCopyrightText: 2020 - 2022 UnionTech Software Technology Co., Ltd. +// SPDX-FileCopyrightText: 2020 - 2026 UnionTech Software Technology Co., Ltd. // // SPDX-License-Identifier: GPL-3.0-only @@ -171,6 +171,14 @@ void QtBaseInstaller::checkError() } qInfo() << "begin check error"; + + // Check if the partition device still exists (handles physical USB removal) + if (!QFile::exists(m_strPartionName)) { + qCritical() << "Error::get(Error::USBMountFailed) device removed:" << m_strPartionName; + emit progressfinished(m_progressStatus, BMHandler::ErrorType::USBMountFailed); + return; + } + QString strDisk = XSys::DiskUtil::GetPartitionDisk(m_strPartionName); if (strDisk.isEmpty()) {
