The integration suite has never run against DragonX. Six independent
defects stacked up, each only visible once the previous was fixed:
1. test_framework used python2 implicit relative imports
("from authproxy import ..."), removed in python3, so every test died
at import. Made explicit relative imports.
2. It wrote ZZZ.conf -- a Komodo assetchain convention -- while DragonX
reads DRAGONX.conf. The daemon therefore never saw the generated
config, fell back to mainnet defaults and tried to bind RPC 21769,
which on a seed node is already held by the real node.
3. start_node() was hard-wired for the -ac_name=ZZZ assetchain tests: it
took the RPC port from extra_args[3], passed extra_args[0] as argv[0]
of the CLI, and only wrote a config when extra_args[0] matched. Any
test that passes no extra args crashed on len(None). The generic path
now takes the port from rpc_port(i) -- the same helper
initialize_datadir() already used -- and drives the CLI with -datadir.
4. dragonxd refuses to start without an asmap file, which no test datadir
had. initialize_datadir() now provisions one.
5. -asmap relative paths resolve against the NET-SPECIFIC datadir, so a
copy in <datadir> is never found. Pass an absolute path.
6. Worst: -regtest was only ever set as "regtest=1" in the conf file,
which DragonX ignores. Every "regtest" node therefore ran on MAINNET:
real genesis, real seeds, real peers. An observed run synced 196,180
live blocks and 679MB into /tmp before the test timed out. -regtest is
now passed as a command-line flag, with -connect=0 so an isolated
regtest node stays off the public network.
With these, nodes start, RPC answers, and tests run to a real result.
They do not all pass yet -- getblocktemplate.py reaches an assertion --
but that is now a test outcome rather than a harness failure.
