This commit moves functions start_node, start_nodes, stop_node and
stop_nodes functions into the BitcoinTestFramework class. It also moves
the bitcoind_processes dict and coverage variables into BitcoinTestFramework.
Adds new functional test, dbcrash.py, which uses -dbcrashratio to exercise the
logic for recovering from a crash during chainstate flush.
dbcrash.py is added to the extended tests, as it may take ~10 minutes to run
Use _Exit() instead of exit() for crash simulation
This eliminates stderr output such as:
terminate called without an active exception
or
Assertion failed: (!pthread_mutex_destroy(&m)), function ~recursive_mutex, file /usr/local/include/boost/thread/pthread/recursive_mutex.hpp, line 104.
Eliminating the stderr output on crash simulation allows testing with
test_runner.py, which reports a test as failed if stderr is produced.
A few "a->an" and "an->a".
"Shows, if the supplied default SOCKS5 proxy" -> "Shows if the supplied default SOCKS5 proxy". Change made on 3 occurrences.
"without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command".
Removed duplicate words such as "the the".
This has no effect on the outcome of test cases, but
prints shorter and less confusing tracebacks on fails.
I.e. does not print an obvious "ConnectionRefusedError"
when shutting down the nodes due to an invalid return code.
Better to check that rpcuser and rpcpassword exist then to check for
the cookie in the test framework.
Name an argument for consistency in p2p-segwit.py
This commit marks the start/stop functions in util.py as private module
functions. A future PR will remove these entirely and move the
functionality directly into the BitcoinTestFramework class, but setting them as
private in this PR will prevent anyone from accidentally calling them
before that future PR is merged.
All Node classes in individual test cases subclass from NodeConnCB. Many
have duplicate definitions for methods that are defined in the base
class. This commit removes those duplicate definitions.
This commit removes ~290 lines of duplicate code.
This commit adds some helper functions to NodeConnCB which are useful
for many tests:
- NodeConnCB now keeps track of the number of each message type that
it's received and the most recent message of each type. Many tests
assert on the most recent block, tx or reject message.
- NodeConnCB now keeps track of its connection state by setting a
connected boolean in on_open() and on_close()
- NodeConnCB now has wait_for_block, wait_for_getdata,
wait_for_getheaders, wait_for_inv and wait_for_verack methods
I have updated the individual test cases to make sure that there are no
namespace problems that cause them to fail with these new definitions.
Future commits will remove the duplicate code.
This commit reduces spammy logging by the test framework. It truncates
logging send/receive message in mininode to 500 characters. mininode
was previously logging the entire message sent received, which can be up
to 1MB for a full block.
sync_with_ping currently returns false if the timeout expires, and it is
the caller's responsibility to fail the test. However, none of the tests
currently assert on sync_with_ping()'s return code. This commit adds an
assert to sync_with_ping so the test will fail if the timeout expires.
This commit also removes all the duplicate implementations of
sync_with_ping() from the individual tests.
This commit merges the NodeConnCB and SingleNodeConnCB into a single
class (called NodeConnCB). The original intent for the NodeConnCB was to
be able to have a python 'mininode' connect to multiple running
bitcoinds. This has never been used and can be achieved more easily by
having multiple NodeConns backed by a common datastore if it is ever
needed.
The changes in mininode.py are just code moves (and merging the two
classes into a single class). The code changes in the individual test
cases are changing the subclasses to subclass from NodeConnCB instead of
SingleNodeConnCB. There is a lot of duplicate code in the subclasses
that can be removed in future commits.
Currently, functional test cases can either pass or fail. There are
occasions when it is helpful to skip tests, for example if the
system they are running on does not meet the requirements for the test.
The rest of the test suite can run without being marked as a failure.
This commit adds framework for tests to skip if their requirements
aren't met.
