目前在 Windows上的Ubuntu Bash上运行llvm,clang,clang-format和clang-modernize.我想使用谷歌发布的一套清理工具,包括地址,内存和线程清理. fsanitize选项似乎都不起作用.

以下是ASAN的代码示例：

#include <stdlib.h>
int main() {
  char *x = (char *)malloc(10 * sizeof(char *));
  free(x);
  return x[5];// purposely accessing deallocated memory
}

这是windows上bash的clang调用：

$clang++-3.5 -fsanitize=address -o1 -fno-omit-frame-pointer -g main.cpp -o main
$./main

结果

==70==Sanitizer CHECK Failed: build/buildd/llvm-toolchain-snapshot-3.5/projects/compiler-rt/lib/sanitizer_common/sanitizer_procmaps_linux.cc:211 ((IsOneOf(*current_,'s','p'))) != (0)(0,0)

我喜欢关于如何使它工作的建议,或者我是否缺少工具链的一部分或其他东西.

如果失败,我想我会双启动Ubuntu或Debian,因为Windows的clang缺少像std：out支持这样的简单功能,尽管理想情况下我希望能够为Windows目标和Linux目标编译.我想避免双启动,因为Ubuntu无法安装Windows存储空间,但它们似乎很好地服务于Windows上的Ubuntu bash.

快速浏览一下源代码–MemoryMappingLayout :: Next – https://llvm.org/svn/llvm-project/compiler-rt/trunk/lib/sanitizer_common/sanitizer_procmaps_linux.cc – 看来问题是在windows上支持/ proc文件系统的ubuntu上的bash是不完整的.

失败的代码是查看/ proc / self / maps – 实际上 – 看起来是正确的.

但是我发现/ proc中的其他东西(例如网络)在bashonwindowsonunix上完全破坏了 – 所以我很确定这部分是正在进行的工作.

我正在创建一个 Windows 10 UWP应用程序,其中涉及BackgroundDownloader,这只适用于桌面而不是手机.

码：

var dl = new BackgroundDownloader();
    dl.CostPolicy = BackgroundTransferCostPolicy.Always;
    file = await localSoundsFolder.CreateFileAsync(name,CreationCollisionoption.ReplaceExisting);
    if (file != null)
    {
        var d = dl.CreateDownload(new Uri(uriTodownloadFrom,UriKind.RelativeOrAbsolute),file);
        d.Priority = BackgroundTransferPriority.High;

        var progressCallback = new Progress<DownloadOperation>(x => DownloadProgress(x,sc)); 
        try
        {
            await d.StartAsync().AsTask(cancellationToken.Token,progressCallback);
            //After this line it doesn't progress!
            CancellationTokenSource token = Utility.cancellationList[sc];
            if (token != null)
            {
                token.Cancel();
                Utility.cancellationList.Remove(sc);
                Debug.WriteLine("The sc has been removed from the download list");
            }
        }
        catch
        {
            return;
        }
    }


private static void DownloadProgress(DownloadOperation download,SoundClass sc)
{
    Debug.WriteLine("Callback");
    var value = download.Progress.BytesReceived * 100 / download.Progress.TotalBytesToReceive;
    Debug.WriteLine("The bytesReceived is {0} and total bytes is {1}",download.Progress.BytesReceived.ToString(),download.Progress.TotalBytesToReceive.ToString());
    new System.Threading.ManualResetEvent(false).WaitOne(10);
    sc.downloadProgress = value;
    if (download.Progress.Status == BackgroundTransferStatus.Completed || value >= 100)
    {
        Debug.WriteLine("DONE donwloading the file {0}",download.ResultFile.Name);
        Debug.WriteLine("The file name happened to be to be added was " + download.ResultFile.Name);
        string fileName = download.ResultFile.Name;
    }
}

行等待d.StartAsync().AsTask(cancellationToken.Token,progressCallback);该计划不进行.而且也没有错误.这不仅适用于手机在桌面上完美运行！我错过了什么？

BackgroundDownloader和我认为Windows UWP中的所有BackgroundTasks都难以使用它们. 您必须首先在当前解决方案中创建一个新的解决方案作为Windows运行时组件. 之后,您必须通过Package.AppxManifest链接它. 呃,不要忘记将运行时组件作为主项目的参考. 如果你做这些事情,希望它必须是有效的.但请确保您有一个RuntimeComponent并将其链接到您的项目中
