使用Sharpziplib解压缩24GB tar.gz

Question

我目前有一个提取tar.gz的进程，但当前进程无法处理超过4GB的内存...我想知道我做错了什么，导致我使用sharpzip lib出错了，它说参数长度不能小于零...。所有注释掉的代码都是当前过程

请看下面的代码，并给我指示

public static void ExtractTarGZFiles(string strExtractionPath, string strInboundFolder)
    {
        List<string> files = new List<string>();
        string strFile = Path.GetFullPath(ConfigurationManager.AppSettings["InboundFolderPath"].ToString());
        if (mblnRunForFile)
        {
            System.IO.FileInfo ioInfo = new FileInfo(mstrFilename);
            strFile = ioInfo.DirectoryName;
            files.Add(ioInfo.Name);

        }
        else
        {
            files = System.IO.Directory.GetFiles(ConfigurationManager.AppSettings["InboundFolderPath"], "*.gz").ToList();
        }

        foreach (string file in files)
        {
            try
            {
            //string stFilePath = file;
            //string testingthisdamnthing = strInboundFolder + mstrFilename;
            //FileStream xstream = new FileStream(stFilePath, FileMode.Open, FileAccess.Read, FileShare.None);
            //xstream.Close();
            //string strTemp = ConfigurationManager.AppSettings["ExtractTempFolderPath"];
            //TarArchive objTA = TarArchive.CreateInputTarArchive(new GZipStream(new FileStream(stFilePath, FileMode.Open, FileAccess.Read), CompressionMode.Decompress));
            //objTA.ProgressMessageEvent += ExtractTarNotifier;
             //objTA.ExtractContents(strTemp);



            //DirectoryInfo dirtemp = new DirectoryInfo(strTemp);
            DirectoryInfo dirExtract = new DirectoryInfo(strExtractionPath);

            Stream inStream = File.OpenRead(stFilePath);
            Stream gzipStream = new GZipInputStream(inStream);

            TarArchive tarArchive = TarArchive.CreateInputTarArchive(gzipStream);
            tarArchive.ExtractContents(ConfigurationManager.AppSettings["ExtractFolderPath"]);
            tarArchive.Close();

            gzipStream.Close();
            inStream.Close();
            //while (IsFileExistsinTempPath(dirtemp, dirExtract))
            //{
            //    //Do nothing
            //}
            //CopyFilesFromTempToExtract(dirtemp, dirExtract);
            //objTA.Close();
            //Logger.Write(" Tar.Gz files Decompressed Successfully");
            MonthLog.Log("Tar.Gz files Decompressed Successfully", "Month", 3, 2, System.Diagnostics.TraceEventType.Information, mstrFilename);

Answer 1

如果您的应用程序为x86，则每个进程只能有4GB的内存。 编译为x64以使用更多资源。

Answer 2

这来自您正在使用的ZipLibrary。 您需要将应用程序编译为x64程序，并在64位环境中运行它。

    // To permit the zip to be unpacked by built-in extractor in WinXP and Server2003, WinZip 8, Java, and other older code,
    // you need to do one of the following: Specify UseZip64.Off, or set the Size.
    // If the file may be bigger than 4GB, or you do not need WinXP built-in compatibility, you do not need either,
    // but the zip will be in Zip64 format which not all utilities can understand.

Answer 3

我为您提供了三种潜在的解决方案，但是我无法告诉您它们中的任何一种是否切实可行。

1. 使用“ 从流中解压缩”示例通过内存流式传输它，因此您无需加载整个内容（这就是为什么现在失败）的原因。
2. 切换到使用DotNetZip ，它可能具有更多选项来处理x86机器上的大文件。
3. 查找可以编写脚本或可以监视目录的常规解压缩应用程序，并在将其解压缩到应用程序之前对其进行解压缩。
