This dead check prevented detecting the end of block files with null-byte padding, causing the script to hang in an infinite read loop.",
  "problem": "Users running `linearize-data.py` against block directories where files end with preallocated zero padding (such as pruned nodes or unfinished files) encounter an indefinite hang instead of cleanly moving to the next file or exiting.",

As aman21-droid explains, 'Indexing a bytes object returns an int in Python 3, so inhdr[0] == \"\\0\" is always false and the zero-padding check never fires.' Because linearize is a niche offline tool, this is worthwhile maintenance rather than a release blocker."

The issue reliably hangs the script when reading unfinalized block files or when reading pruned datadirs. It is a one-line bug fix with a provided reproduction, currently awaiting initial review."
