For performance reasons we were starting one for each session, which caused
the same postgres DB to be re-used for multiple tests (all test run in the
same worker process), but this could lead to interactions if there is a
timeout or a test happens to touch the `db_provider`. It turns out that we
were only saving about 15 seconds on a 1250 second run anyway, which is a
small cost for increased test isolation.
We were not removing the base test directory if we had other files in there,
which was the case for postgres runs. This now explicitly check for `test_*`
directories which are an indicator of a failed test.
We had a couple of issues with workers dying and attempting to re-initialize
the database while it was already initialized. This will look for a free
directory and just start the DB in there, allowing workers to be better
isolated.
The next patch perturbed things enough that we suddenly started
getting (with --track-origins=yes):

This is because there is uninitialized padding at the end of struct
peer_state.

And when it's set, and we're SLOW_MACHINE, simply disable valgrind.
Since Travis (SLOW_MACHINE=1) only does VALGRIND=1 DEVELOPER=1 tests,
and VALGRIND=0 DEVELOPER=0 tests, it was missing tests which needed
DEVELOPER and !VALGRIND.
Instead, this demotes them to non-valgrind tests for SLOW_MACHINEs.

We can query all the txids at once, rather than one at a time.
Doesn't make any measurable difference to full runtime testing here
though.

We might have funds prior to calling join_nodes(), so testing that
we've all seen the block is better.

This is what fund_channel() does, which is more thorough than what
we were doing. But since the order of the logs is undefined, we need
to be a little careful.

Reduces VALGRIND=1 node_factory.line_graph(5) time on my laptop from 42s to 36s.
This is simply because forking all the subdaemons just to check the
version is very expensive under valgrind.

Telling `lightningd` to pass a `-datadir` to `bitcoin-cli` so it doesn't go
snooping where it doesn't belong (i.e., the user's home directory and config).

This was breaking a couple of tests if the pyln version was not synced up with
`lightningd`, so now we just warn (these are then collected when running in
pytest and highlighted).
We only support a very limited number of argument combinations, and apparently
sometimes we trigger a case we aren't handling. This adds a more useful error
message, including the params we didn't match.
So far we've always cleared the node directory when provisioning the node, but
while testing some plugins we noticed that pre-generating some files in that
directory is useful. This just adds yet another flag to `get_node` that
disables deleting any existing node directory.
A CONSERVATIVE/3 target for them.
Some noisy changes to the tests as we had to update the estimatesmartfee
mock.
Changelog-Changed: We now use a higher feerate for resolving onchain HTLCs and for penalty transactions
We kept track of an URGENT, a NORMAL, and a SLOW feerate. They were used
for opening (NORMAL), mutual (NORMAL), UNILATERAL (URGENT) transactions
as well as minimum and maximum estimations, and onchain resolution.
We now keep track of more fine-grained feerates:
- `opening` used for funding and also misc transactions
- `mutual_close` used for the mutual close transaction
- `unilateral_close` used for unilateral close (commitment transactions)
- `delayed_to_us` used for resolving our output from our unilateral close
- `htlc_resolution` used for resolving onchain HTLCs
- `penalty` used for resolving revoked transactions
We don't modify our requests to our Bitcoin backend, as the next commit
will batch them !
Changelog-deprecated: The "urgent", "slow", and "normal" field of the `feerates` command are now deprecated.
Changelog-added: The fields "opening", "mutual_close", "unilateral_close", "delayed_to_us", "htlc_resolution" and "penalty" have been added to the `feerates` command.
pytest captures the output by monkey patching out `sys.stdout`. This may
conflict with our use of `sys.stdout` when configuring logging, resulting in
the "Write to closed file" issue that is spamming the logs. By making the
logging configuration a fixture hopefully we always use the correct
stdout (after pytest has monkey-patched it).
For some reason we fail to remove the test directory in some cases. My
hypothesis is that it is a daemon that is not completely shut down yet, and
still writes to the directory. This commit intercepts the error, prints any
files in the directory and re-raises the error. This should allow us to debug
the reappears.
Some tests may not spawn a node at all, so make sure that our assumption that
the directory exists in the fixture cleanup is correct by creating the
directory.
if the node fails to start (and we're expecting it to) return to us the
node object anyway
we also signal to collect all of its stderr logs by setting stderr
on the tailableproc that backs the node
The `generate` has been deprecated since 0.16 and has been removed in 0.18.0
so we better use `generatetoaddress` instead, which is already what we do with
`bitcoind`. So we remove the override here.
This will change some `requirements.txt` of pyln-testing in a way that
it does not require different package version i.e. to `tests/requirements.txt`.
The reason for this is that users are not forced to hassle with pyenv
or virtualenv and could just use `--user`.
```bash
pip install --user -r tests/requirements.txt -r contrib/pyln-testing/requirements.txt

We were hardcoding the chainparams->chain_hash which caused the query to
return an empty result. By parametrizing the test we can make it work on
elements.
In the c-lightning tests we have `tests/conftest.py` which annotates test
function with the outcome. If we use pyln-testing outside of the c-lightning
tree we cannot rely on that annotation being there, so we assume it passed.
