test_framework accepts a new --usecli parameter. Running the test with
this parameter will cause all RPCs to be sent through bitcoin-cli rather
than directly over http. By default, individual test cases do not
support --usecli, and self.supports_cli must be set to True in the
set_test_params method.
We can make supports_cli default to True in future once we know which
tests will fail with use_cli.
Change TestNodeCLI.__call__() to return a new instance instead of modifying the
existing instance. This way, it's possible to create different cli objects that
have their own options (for example -rpcwallet options to connect to different
wallets), and options set for a single call (`node.cli(options).method(args)`)
will no longer leak into future calls.
node_network_limited had a race condition, since wait_for_block()
doesn't do what you might expect. It only checks the most recent block
received over the P2P interface (perhaps we should rename the method
wait_for_most_recent_block() to avoid future confusion). The test can
fail if the node sends us invs for other blocks, we respond with a
getdata, and the node sends us one of those blocks in the 0.05 second
wait_until loop window.
Fix this by not responding to inv messages with getdata messages.
assumevalid.py, example_test.py and p2p-acceptblocks.py add
p2p_connections after the NetworkThread has been started. This isn't
permitted. Fix test to restart the network thread when adding new
connections.
p2p-leaktest.py had a potential race condition if the NetworkThread
hadn't terminated by the time we tried to restart it.
Add network thread_start(), network_thread_running() and
network_thread_join() utility functions in mininode.py and use
network_thread_running() in network thread assertions.
Instead of calling combine_logs from test_runner when the environment variable
PYTHON_DEBUG is set, add a combinedlogslen argument. This makes it easier
to call when running locally, and allows a different length of combined logs
to be printed.
This commit moves the logic that sends a version message
on connection from NodeConn to NodeConnCB. NodeConn should
not be aware of the semantics or meaning of the P2P payloads.
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.
NodeConn can now be swapped out for any other implementation
of a low-level connection without changing client code.
