sylabs/squashfs (WIP)

This is a fork of CalebQ42/squashfs for the purpose of maintaing a package that removes the lzo dependency, so that it does not contain GPL code.

Branches

• remove-lzo - main from CalebQ42/squashfs with LZO support removed.
• remove-lzo-vX.Y.Z - vX.Y.Z from CalebQ42/squashfs with LZO support removed.

Tags

• vX.Y.Z - vX.Y.Z from CalebQ42/squashfs with LZO support removed.

A PURE Go library to read and write squashfs.

Currently has support for reading squashfs files and extracting files and folders.

Special thanks to https://dr-emann.github.io/squashfs/ for some VERY important information in an easy to understand format. Thanks also to distri's squashfs library as I referenced it to figure some things out (and double check others).

TODO

Limitations

• No Xattr parsing. This is simply because I haven't done any research on it and how to apply these in a pure go way.

Performance

This library, decompressing the Firefox AppImage and using go tests, takes about twice as long as unsquashfs on my quad core laptop. (~1 second with the library and about half a second with unsquashfs).

My recents tests have shown the Firefox AppImage might be an outlier and this library might be considerably slower (4x ~ 6x time slower then unsquashfs)
