Using .WithZipFile and .WithZipFileStream sometimes gives System.IO.IOException #419

Closed simohr closed 4 years ago

simohr commented 4 years ago

When starting WebServer with a zip file I sometimes get this exception System.IO.IOException. Sometimes it works as expected and loads all files. Sometimes I get this exception and sometimes it loads the server but with some files missing (local header corrupted). I am attempting to run the server on a Xamarin.Android app. Any help would be appreciated.

Hi.

Do you have a similar issue with Windows or Linux?

simohr commented 4 years ago

I am using Macos Catalina(10.15.2) and Visual Studio for Mac (8.3.11). I would also like to note that when testing the WebServer on a simple Console App it could not open zip files created with the Mac system(Archive Utiliy or Keka), however I suppose this has more to do with System.IO.Compression.

According to the results of a quick Google search there seem to be some long-standing bugs in MacOS's ZIP archiving utilities. I don't know if this completely explains the problems @simohr is experiencing, but I'd suggest using ZIP files created on a Windows or Linux system, or at least verify that a ZIP file can be correctly extracted on a Windows or Linux system before using it with EmbedIO - or with System.IO.Compression at all.

@simohr can you confirm that the problem goes away if all involved Zip files were created on other systems? If so, can we close this issue?

Yes, using zip files from other systems works fine.
