"""Test asmap config argument for ASN-based IP bucketing. |
|
|
|
Verify node behaviour and debug log when launching bitcoind in these cases: |
|
|
|
1. `bitcoind` with no -asmap arg, using /16 prefix for IP bucketing |
|
|
|
2. `bitcoind -asmap=<absolute path>`, using the unit test skeleton asmap |
|
|
|
3. `bitcoind -asmap=<relative path>`, using the unit test skeleton asmap |
|
|
|
4. `bitcoind -asmap/-asmap=` with no file specified, using the default asmap |
|
|
|
5. `bitcoind -asmap` with no file specified and a missing default asmap file |
|
|
|
6. `bitcoind -asmap` with an empty (unparsable) default asmap file |
|
|
|
The tests are order-independent. |
