That is, without having to launch with test_runner.py. There are
several places where the BITCOIND environment variable determines the
executable, but the default is "bitcoind"; change the default to
"src/zcashd". This does require running the test from the top-level
directory.
Also change the environment variable from BITCOIND to ZCASHD. This could
conceivable break someone, but it just makes too much sense not to do.
Prior to this change, calling `join_network` after a network split
only worked in the case that no new non-coinbase transactions were
created during the network partition; in the case that such a
transaction was created, `join_network` would fail when waiting
for mempool synchronization, because zcashd nodes do not.
automatically broadcast their mempool contents on restart.
This change modifies `setup_network` to wait for mempool synchronization
or not on the basis of a newly added do_mempool_sync flag. In the
case of `join_network`, this flag is set to `False`; the default value
is set to `True` to preserve previous functionality elsewhere.
Tests should explicitly use the `resendwallettransactions` RPC method
to ensure that mempool transactions are rebroadcast before attempting
to synchronize the network after a `join_network` call.
Thanks to @MarcoFalke @dexX7 @laanwj for review.
Zcash: Includes all the backend changes, but excludes the --coverage flag
added to rpc-tests.py as we have not yet migrated away from rpc-tests.sh.
