Streaming zip file is going to have issues when compression ratio is not 0 for some implementations (such as ZipFileStream from Java / Android). I fixed this a few years ago for ZipZap: https://github.com/pixelglow/ZipZap/pull/155
Particularly, the local header (per file) is written before the file content, and you cannot get accurate compressed size prior to actual compression. Central file header is at the end of the file, so there is no problem to get accurate compressed size, but some zip reader implementations (such as ZipFileStream) cannot use central file header (because it is at the end), and will use the wrong compressed size.
How does it compares to https://github.com/kbbdy/zipstream?
The code is perplexing. Why do you need to say int('0x1', 16) and int('0x2', 16)? Why not just write 0x1 and 0x2? Or just plain 1 and 2?
I'm also perplexed by the goal as this seems to just call zipfile.write under the hood, which already does what this tries to accomplish?
