ab_decrypt's Issues

Error "invalid distance code" with large backups

ab-decrypt works fine for small .ab files, but for large .ab files, e.g. a backup of 317 MB, I get at some point:

zlib.error: Error -3 while decompressing data: invalid distance code

The partly written tar output file is ok for the part it already wrote (284 MB in case of the 317 MB backup), but it is incomplete.

This is with ab-decrypt 1.0.0 (pip install in a Pythoin 3.9.12 venv).

missing shebang

The first line should be the standard hashbang (#! /usr/bin/env python3) to allow for this to work:

wget ...
chmod +x ./ab_decrypt
./ab_decrypt

Note that it is python3 because PEP 394 allows python to not work or not point to version 3, so technically the README usage examples should also be corrected.
