f97ab35fa qa: Fix bug introduced in p2p-segwit.py (Suhas Daftuar)
a7820422e qa: Treat mininode p2p exceptions as fatal (Suhas Daftuar)
Pull request description:
#11121 inadvertently broke the constructor for the `TestNode()` object in `p2p-segwit.py`, silently breaking at least one of the tests.
Although the python code was raising exceptions due to a `TestNode()` object not existing (or having the right type), mininode was masking these from anyone running the test through the test_runner (like travis), because it catches all exceptions during message delivery and just prints a log message and continues. Such "graceful" handling of errors is almost certainly something we don't want in our test suite, so the first commit here attempts to prevent that type of failure from ever being masked.
The second commit fixes the particular bug in `p2p-segwit.py`.

1817398b3 mininode: add an optimistic write and disable nagle (Cory Fields)
Pull request description:
Disclaimer: I'm not familiar with asyncore, so I'm unclear how safe this is. It works for me (tm).
Because the poll/select loop may pause for 100msec before actually doing a send, and we have no way to force the loop awake, try sending from the calling thread if the queue is empty.
Also, disable nagle as all sends should be either full messages or unfinished sends.
This shaves an average of ~1 minute or so off of my accumulated runtime, and 10-15 seconds off of actual runtime.

0063d2c3d [tests] Make p2p-leaktests.py more robust (John Newbery)
Pull request description:
There has been an example of p2p-leaktests.py failing on travis in the new service bits test (introduced in #11001 . It appeared to me that the previous p2p connections had not been fully disconnected before attempting to add new p2p connections.
I've added a sleep and restarted the NetworkThread, but I don't know whether this will fix the problem, since I'm unable to reproduce the failure locally.
@MarcoFalke - not sure what you want to do here? I don't think this change could make things any worse.

In v0.15, we disconnect nodes that send us version messages with
unsupported service bits (1 << 5 and 1 << 7). This commit adds a test
that bitcoind will disconnect those nodes before August 1st 2018, and won't
disconnect those nodes after August 1st 2018.

Removed duplicate words such as "the the".
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.
