This allows us to re-use existing tests (assuming the call and fields
are covered by `cln-rpc` and `cln-grpc`) to test the full roundtrip
from test over the grpc interface to the json-rpc interface and back
again.
You can switch to the grpc interface by setting the `CLN_TEST_GRPC`
environment variable to 1, but for now only very few shims are
implemented (due to the non-generated nature of LightningRpc).
To test the grpc interface we'll want to emulate the JSON-RPC
interface as best we can, hence when talking to the grpc interface we
want to convert back into a parsed JSON format as LightningRpc would
have returned it. This is just the simplest way of closing the loop
here:
```
pyln-testing --grpc-> cln-grpc --grpc2json
^ |
| v
| JSON-RPC
| |
TEST v
^ CLN
| |
| v
pyln-testing <-grpc2py-- cln-grpc <- json2grpc
```
These may eventually end up in pyln-client, as they allow talking to
the GRPC interface exposed by cln-grpc, however for now they are used
for testing only. Once we have sufficient API and test coverage we can
move them and leave imports in their place.
Since we now log directly, we don't prepend the prefix ourselves, making it really
hard to tell *which* lightningd the log applies to!

Even though we generally wait until a node has seen the gossip,
that doesn't mean that connectd has processed it! This means when
we connect it may still send us "old" gossip.
So we set the OPT_GOSSIP_QUERIES bit, which means don't send until we
ask. But now it sends us WIRE_QUERY_CHANNEL_RANGE, so everyone needs
to filter that out.

I saw another "only_one()" fail on alias checking: it's not

Some flakes are caused by weird races in this code. Plus, if we
get things to write straight to files, we might see things in
there on post-mortem which happen after the python runner exits.
It's a bit less efficient, but much simpler. Let's see if it helps!

Over time, it has cost us more developer cycles than it has gained.
It has hidden intermittant bugs, and allowed cruft to accumulate:
when we eventually tried to figure out what was going wrong, the
actual change which caused it was now stale and forgotten.
This was a particular bane during the connectd rewrite, and I
worked through some issues which had occurred before, but were not
more likely.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
So this was quite a journey:
- We want relative depdendencies (using the `path` argument) whenever
developing locally. Otherwise we would have to install each
dependency every time we change a single character, which
undoubtedly would cause us to waste time trying to debug an issue
just because we forgot to install.
- When publishing however we want to rely on the version number,
since the repo context gets lost upon publishing, and path
dependencies cause failures.
The solution then it seems is to use `dev-dependencies` (not that
surprising once you find it) with relative paths, so that `poetry
install` uses these over the normal dependencies (no idea how they
dedup them) and use `dependencies` when publishing. The paths are
still in there when publishing, but `pip install` ignores them.
I checked that `poetry install` from an unrelated project doesn't
accidentally use the path dependencies, even when adding them as
dev-dependencies. This should hopefully also allow installing them
as a repo link, though I can't test that right now.
We should be using amount_msat always. Many tests were not. Plus,

* close `feerange` is a feerate type.
* datastore/deldatastore/listdatastore `key` can be singleton.
* delexpiredinvoice: `maxexpirytime` is not required, is a u64.
* invoice/delinvoice/listinvoice `label` can be an integer
* fundpsbt: many fields are u32 not number (JSON for int or float).
* invoice: `msatoshi` can be "any".
* invoice: `expiry` has a type (now must be numeric).
* invoice: `exposeprivatechannels` can be bool or array of scids.
* invoice: `deschashonly` added
* keysend: there's no "float" type, use "number" or "u32" etc.
* keysend: `routehints` is a valid arg, as is `extratlvs` (EXPERIMENTAL_FEATURES)
* listdatastore: `key` is not required.
* newaddr: `addresstype` can be "all"
* pay: `exemptfee` is "msat", new fields `locaofferid` and `exclude`
* sendonion: was mis-formatted, missed `localofferid` and `groupid` fields.
* sendpay: add `localofferid` and `groupid` params.
* signpsbt: add `signonly` param.

- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".

This 'fixes' the `wait_for` helper by removing a pointless final
`time.sleep()`, thus potentially making the method return quicker.
The old code could have had three final states:
- success() := True
- Timeout and success() := True
- Timeout and success() := False
The new code has just two final state:
- success() := True
- Timeout and success() := False
It ensures the final `time.sleep()` is just the right amount before timeout.
And more importantly making it more readable :-)

We are printing `repr(obj)` which is not pretty-printed, hard to read,

We were getting a couple of starvations, so we need a fair filelock. I

We were getting a number of incompatibility warning due to the

definitions to being compatible with a known good version, and while

Both my machine and apparently the CI tester machines regularly run
into issues with load on the system, causing timeouts (and
unresponsiveness). The throttler throttles the speed with which new
instances of c-lightning get started to avoid overloading. Since the
plugin used for parallelism when testing spawns multiple processes we
need to lock on the fs. Since we have that file open already, we'll
also write a couple of performance metics to it.
We sometimes have very specific sequences of tx broadcasts and blocks
being generated to confirm them. If the confirmation is missed the
test can completely get out of sync. Make debugging this easier by
logging what we confirmed.
Logs may contain non-ASCII and non-UTF8 symbols, which crashes the
tailer. It's better to replace them with a glyph representing
undecodeable symbols instead, and handle the issue further up the
call-chain.
We rely on it when logging, but didn't set it in the class, rather we
did in the sub-classes. This proved to be rather annoying to search
since it'd just fail silently and not log any output.
This will change the current hardwired PostgreSQL binary lookup mechanism to
utilizing the `pg_config --bindir` utility that should work better for most
distributions. The old method caused issues at least on Archlinux.
Changelog-None
Since we start a new instance of postgres for each test we may end up swamped
and the startup can take a bit longer. So let's loop until we get a success.
It was really flaky, especially under `test_mpp_interference_2`, most likely
due to multiple calls to `fund_channel`. This commit looks for the specific
txids in the `listfunds` output and the `getrawmempool` output, avoiding
strange artifacts from multiple calls.
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):

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.

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.
Using the psycopg2-binary package means that the apropriate compiled binary
for the user platform will be shipped alongside the python binaries. Otherwise
the python bindings and the C shims would be shipped which would then require
the postgres development packages as well.
This just makes things easier, since we don't require the build dependencies.

Quite a few of the things in the LightningNode class are tailored to their use
in the c-lightning tests, so I decided to split those customizations out into
a sub-class, and adding one more fixture that just serves the class. This
allows us to override the LightningNode implementation in our own tests, while
still having sane defaults for other users.
We were relying heavily on NodeFactory to do some magic before instantiating
the Node with rpc and daemon initialized, that meant that we'd have to replace
all 3 classes when customizing the node to our needs. Moving that
initialization into the node itself means that the LightningNode class now can
be swapped out and customized, without having to wire everything else through.
`DEVELOPER=1` assumes that the binary has been compiled with developer set to
true, which might not be the case for plugin developers. Setting this to 0 by
default has no effect in c-lightning since we always at least set it in
`config.vars` but may prevent some issues outside.
We'll rewrite the tests to use this infrastructure in the next commit.
Changelog-Added: The new `pyln-testing` package now contains the testing infrastructure so it can be reused to test against c-lighting in external projects
