When extracting a zip-file that was created using the ZipArchive class on Linux the resulting files have no permissions and cannot be opened.
Even changing the permissions using chmod has no effect.
I'm creating a simple .zip file using this code:
static void Main(string[] args)
{
using (var fileStream = new FileStream("test.zip", FileMode.CreateNew))
{
using (var archive = new ZipArchive(fileStream, ZipArchiveMode.Create, leaveOpen: true))
{
ZipArchiveEntry entry = archive.CreateEntry("testfile.txt");
using (var writer = new StreamWriter(entry.Open()))
{
writer.WriteLine("This is a test file.");
}
}
}
}and extract it using unzip:
$ ls -l
...
-rw-r--r-- 1 marcus marcus 150 Nov 24 16:17 test.zip
...
$ unzip test.zip
Archive: test.zip
inflating: testfile.txt
$ ls -l
...
---------- 1 marcus marcus 21 Nov 24 16:17 testfile.txt
-rw-r--r-- 1 marcus marcus 150 Nov 24 16:17 test.zip
...
$ cat testfile.txt
cat: testfile.txt: Permission denied
$ chmod +r test.zip
$ ls -l
...
---------- 1 marcus marcus 21 Nov 24 16:17 testfile.txt
-rw-r--r-- 1 marcus marcus 150 Nov 24 16:17 test.zip
...
Using graphical programs to extract it doesn't work either.
$ zipinfo test.zip
Archive: test.zip
Zip file size: 150 bytes, number of entries: 1
?--------- 2.0 unx 21 b- defN 18-Nov-24 16:33 testfile.txt
1 file, 21 bytes uncompressed, 28 bytes compressed: -33.3%
$ dotnet --version
2.1.403
Here is the resulting zip-file for further analysis:
