Why I couldn't untar these specific tar files? #25

Open iori57 opened 9 years ago

iori57 commented 9 years ago

Any files listed here: https://code.google.com/p/tesseract-ocr/downloads/list

For example, this file: https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.deu.tar.gz

It is a tar.gz, I have no problem using another library to extract it to become just tar, however when I tried to use this library it fails to untar it.. I stepped into the code and found that at one point it reach a line with comment "// It's a nul block" and finally "// It's not a tar type" with error "invalid block type"

Any suggestion on what to look for? I tried to use untar command in OSX terminal and it manage to untar the same file without issue so it shouldn't be corrupted. Furthermore I tried on the rest of the files in the download list all of them gives the same behaviour.

Is there different formats for TAR files?

Thanks in advance!

Seems like it is due to the 'L' block type, which means very long file names

How to handle long file names?

I think we're going to properly fork this repo, add the 'L' block type support, and open a PR. Will mention it here!
