Rusty Russell 4cada557ba pytest: don't redirect stderr by default.
Some tests need to inspect it, but most don't, and I suspect I'm missing some
error messages due to this.

Christian Decker b8bcc7d13f pytest: Add a new RPC interface to talk to grpc
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).

Christian Decker 5307586d4d msggen: Add a new generator for grpc -> python converter
To test the grpc interface we'll want to emulate the JSON-RPC

have returned it. This is just the simplest way of closing the loop
here:

move them and leave imports in their place.

Rusty Russell 4970704d24 pytest: fix gossipwith flake harder.
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
entirely clear to me with the more aggressive sending of
own gossip, that we necessarily process in order, so we might
not have actually seen all channels just because we saw
the farthest one.

Get it to log direct to stdout, so we see what's happening *as it

were using before, but that added more problems than it solved.

Rusty Russell a0e0dbf229 pyln-testing: use files for stdout and stderr, not threads.
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!

Some tests need a rework now, since we don't get a failure (except
eventual timeout), but they're simpler.

* "number" means int or float, usually it should be u32.

Specific commands:

* close `id` can be by channel id, scid.
* 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.
* txprepare "outptus" typo.
* waitsendpay: add `groupid` and  fix `partid` type.
* withdraw: `destination` is a bitcoin address, not a pubkey.

```

This is because `pay` returns from l1 when it has the preimage, not
when the HTLC is fully resolved.  Add a helper for this, and call it
at the end of the pay test helper.  We might need this elsewhere
though!

Rusty Russell e6ba66063e pytest: don't valgrind plugins under CI if many nodes.
Just pick one at random to trace fully.

Eg. test_gossip.py::test_getroute_exclude (creates 5 nodes)

Rusty Russell 65bb989cf1 pytest: don't checksum plugins on startup in VALGRIND developer mode.
This loads up 20MB of plugins temporarily; we seem to be getting OOM
killed under CI and I wonder if this is contributing.

Doesn't significantly reduce runtime here, but I have lots of memory.

Christian Decker cc7985df92 pytest: Use the same `TIMEOUT` in `wait_for_route`
This was getting flaky whenever we had multihop routing syncs and had
`DEVELOPER=0`, which uses the slow gossip propagation.

Dustin Dettmer cdb93eefec resolve() appears broken on Python 3.7+
On my machine it should have produced:
/tmp/ltests-1p0v5z1j/.locks/lock-1631090663.1066182
but instead it produced:
/private/tmp/ltests-1p0v5z1j/.locks/lock-1631090663.105848

The mismatch resulted in a hang inside flock.

Path .resolve() seems to be causing problems for others as well. It appears the library was not meant to handle complex path situations and isn't maintained as such (see link reference).

Since we have already built a full path here anyway, the call to .resolve() appears redundant.

Tested on python 3.9.6 on my Mac OS X 11.4 (20F71), Xcode 12.5.1 (12E507)

Vincenzo Palazzo bc1eab8646 Skip following import and skip flask type to mypy code analysis.
As suggested in this issue https://github.com/python/mypy/issues/7484#issuecomment-529363083 we skip following import becuase with the recent version of mypy the __init__.py file make confusione inside the analysis (in the python issue it is unclear the main motivation of this issue. At list unclear to me).
