IZipClient help needed

[mickle026 650]

I am trying to unzip a file that I have downloaded inside a plugin, but all I keep getting is an exception.

If I dont get an exception , nothing is unzipped either.

ZipFile is the Path to the zip including the filename.
extractPath is the directory folder to extract it to.

The header magic is 1F 8B (a gzip)

private readonly IZipClient gzipClient;



using (FileStream fs = File.Open(ZipFile, FileMode.Open))
{
	//gzipClient.ExtractAllFromZip(fs, extractPath, true);
    gzipClient.ExtractAllFromGz(fs, ExtractedZip, true);
}

I thought it would be easy, but I am not getting any extracted files.

 

Is there something I need to do other than the above?

it says path2 is null

try

                    using (FileStream fs = File.Open(ZipFile, FileMode.Open))
                    {
                        log.LogToMyFile(currentlog, DateTime.Now.ToString("dd.MMM.yyy  -  HH'.'mm'.'ss") + $" GZ Unzip:-\nZipFile:{ZipFile} \nExtract To:{extractPath}");
                        gzipClient.ExtractAllFromGz(fs, extractPath, true);
                    }
                }
                catch (Exception e)
                {
                    log.LogToMyFile(currentlog, DateTime.Now.ToString("dd.MMM.yyy  -  HH'.'mm'.'ss") + $" Exception Occured:\n{ZipFile}\n {e.ToString()}");
                }

It seems to be telling me there is a Path.Combine in here ???

How did you create the zip?

[mickle026 650]

The zip is downloaded with web client like any other file.  It works fine , I can unzip it with WinZip/winrar and I am waiting for it's lock to be released before trying to unzip it.

It sounds by your response that I am doing it correctly, and you are looking for other issues...

The download is fine, the paths are fine.  I am not getting any other errors

Value cannot be null. (Parameter 'path2')
   at System.ArgumentNullException.Throw(String paramName)
   at System.IO.Path.Combine(String path1, String path2)

The error is confusing,  what path combine?

 

They only time I use it is to create the zip file path and the output folder.  I log them here:

ZipFile:D:\cache\MechBox\ImdbDatasets\Zips\title.ratings.tsv.gz

Extract To:D:\cache\MechBox\ImdbDatasets

They are valid paths.

What did you pass in for extractedzip?

The directory path to extract to.  The path exists.

D:\cache\MechBox\ImdbDatasets

I think it is something to do with the gz file on imdb's server itself.  If I change the .gz archive name and open it, then the filename inside the archive also changes to the same.

I am therefore assuming the file itself is gz encrypted rather than "containing" a gzip encrypted file - does that make sense?

so I tested with ExtractFirstFileFromGz and it works properly.

It seems I was missunderstanding that the gz format and that it is not a "container" if it only has 1 file, but itself gz encoded.
 

    {
        [Route("/MechBox/ExtractGzip", "Get", IsHidden = true, Summary = "TestingExtractZip")]
        [Authenticated(Roles = "Admin")]
        public class ExtractGzip : IReturn<object>
        {
            public string Text { get; set; }
        }
        public async Task<string> Get(ExtractGzip request)
        {

            Stream fs = GetFileStream(@"D:\cache\MechBox\ImdbDatasets\Zips\title.gz");
            gzipClient.ExtractFirstFileFromGz(fs, @"D:\cache\MechBox\ImdbDatasets","test.tsv"); 

            return JsonSerializer.SerializeToString(new ExtractGzip()
            {
                Text = "Test Done!"
            });

        }
        public static Stream GetFileStream(string fileName) => File.OpenRead(fileName);
