我正在使用 Windows Cloud Filter API 创建虚拟驱动器。删除回调在 Windows Home 21H1 19043.1165 (cldflt.sys 10.0.19041.1110) 上按预期停止工作。如果我从 CF_CALLBACK_TYPE_NOTIFY_DELETE 返回错误代码,则无论如何都会删除脱水占位符,无论我返回的错误代码如何:
void CALLBACK FakeCloudProvider::OnNotifyDelete(
_In_ CONST CF_CALLBACK_INFO* callbackInfo,
_In_ CONST CF_CALLBACK_PARAMETERS* callbackParameters)
{
CF_OPERATION_INFO opInfo = { 0 };
opInfo.StructSize = sizeof(CF_OPERATION_INFO);
opInfo.Type = CF_OPERATION_TYPE_ACK_DELETE;
opInfo.ConnectionKey = callbackInfo->ConnectionKey;
opInfo.TransferKey = callbackInfo->TransferKey;
opInfo.CorrelationVector = callbackInfo->CorrelationVector;
opInfo.RequestKey = callbackInfo->RequestKey;
CF_SYNC_STATUS_MSG* syncStatus = new CF_SYNC_STATUS_MSG;
syncStatus->Code = STATUS_FILE_LOCKED_WITH_WRITERS;
syncStatus->SetMsg(L"MY TEST");
opInfo.SyncStatus = syncStatus;
CF_OPERATION_PARAMETERS params = {0};
params.ParamSize = sizeof(CF_OPERATION_PARAMETERS);
params.AckDelete.Flags = CF_OPERATION_ACK_DELETE_FLAG_NONE;
// I have also tested many other error codes.
params.AckDelete.CompletionStatus = STATUS_FILE_LOCKED_WITH_WRITERS;
HRESULT res = CfExecute(&opInfo, ¶ms);
}
我已经测试了从 Windows 资源管理器和 Windows 21H1 上的命令提示符删除。结果是相同的 - 占位符被删除。
我还重新测试了旧版本的删除 - Windows 10 Pro 1909 (18363.1556) (cldflt.sys 10.0.18362.1533) 并且一切都按预期工作 - 如果我从删除回调中返回错误,则文件不会被删除。
我猜这是最新 Windows 更新中的错误。有人能找到解决这种行为的方法吗?
