buggy feature? rip it out by setting any of the following environment variables to disable its associated bell or whistle,

| `PRTY_NO_IFADDR` | disable ip/nic discovery by poking into your OS with ctypes |
| `PRTY_NO_IPV6` | disable some ipv6 support (should not be necessary since windows 2000) |
| `PRTY_NO_LZMA` | disable streaming xz compression of incoming uploads |
| `PRTY_NO_MP` | disable all use of the python `multiprocessing` module (actual multithreading, cpu-count for parsers/thumbnailers) |
| `PRTY_NO_SQLITE` | disable all database-related functionality (file indexing, metadata indexing, most file deduplication logic) |
| `PRTY_NO_TLS` | disable native HTTPS support; if you still want to accept HTTPS connections then TLS must now be terminated by a reverse-proxy |
| `PRTY_NO_TPOKE` | disable systemd-tmpfilesd avoider |
example: `PRTY_NO_IFADDR=1 python3 copyparty-sfx.py`
