lzma on Linux

[eiselekd]

On Linux the lzma command in recent distributions for decompression via stdin/stdout is:
cat in | lzma -d > out
so this patch is maybe useful:

I don't know if they really care, since there's no response whatsoever so far, but that doesn't work for me. This will do the trick:

import os, sys, struct, hashlib, platform

p = platform.system()

if p == "Darwin":
	args = ["/usr/local/bin/lzmadec", "-"]
elif p == "Windows":
	args = ["lzma", "-d"]
elif p == "Linux":
	args = ["lzma", "d", "-si", "-so"]

process = subprocess.Popen(args, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

Also required for macOS is one of these:

brew install xz

or

sudo port install xz
