Issue: Unzip archives which contains large files #45

Closed Simona-A-R closed 6 years ago

Simona-A-R commented 6 years ago

I have a zip archive which contains several files and one of this file has 421MB size. Grunt unzip throws the following error: Warning: Invalid string length Use --force to continue.

Example:

unzip: {
    src: "dir/*.zip",
    dest: "dir"
}

The archive doesn't seem to be corrupt and it works if I used 7z for example. I can fix this issue by setting checkCRC32: false but I don't know why it is needed. P.S I can't provide the archive since it contains client information.

Would it be possible for me to get a copy of the file? It will be hard for me to debug it otherwise =/

Sorry, but unfortunately I can't provide you that file, it is confidential. I know it is hard for you to debug, you can try with different types of files and with larger size than 400MB, maybe you can find out something. Thank you!

Maybe you can generate another ZIP file via the same confidential process and see if it generates the same error? Based on your CRC32 patch, I have a feeling it's specific to the file

Simona-A-R commented 6 years ago

I have more than one archive with at least one file larger than 400MB inside and I got the same issue. I'll continue to investigate on my side for those specific files.

Cool, I'm going to close this issue for now since it's blocked on my side. We can re-open if we have something to iterate on
