Rusty Russell 68b45c2ae0 pytest: restore prefix to logging.
Since we now log directly, we don't prepend the prefix ourselves, making it really
hard to tell *which* lightningd the log applies to!

Christian Decker 695a98e5d8 pyln-testing: Add `gossip_store` parser to testing framework
I had to parse quite a few of these files debugging zeroconf, so I
thought it might be nice to have direct access here.

Changelog-Added: pyln-testing: Added utilities to read and parse `gossip_store` file for nodes.

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.

Rusty Russell 9137ea262b pytest: don't assume that join_nodes needs only check ends.
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.

Rusty Russell d2952576cd pyln-testing: restore proper streaming behaviour for lightningd.
Get it to log direct to stdout, so we see what's happening *as it
happens* rather than as we read it.  We could restore the thread we
were using before, but that added more problems than it solved.

This means that we need the hsm password prompts in the log though.

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.

Rusty Russell b45b731c55 doc/schemas: fixes for request schemas.
Types are fixed, in particular:

* rename "OutputDesc" to more consistent "outputdesc".
* rename "utxo" to more consistent "outpoint".
* it's "boolean" not "bool".
* "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.

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)

than they are the risk of being cheated.  While we complete our
anchor implementation so we can use low fees there, let's
get less aggressive (we already have 34 or 18 blocks to close
in the worst case).

The changes are:

- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".

There can be no perfect levels, but we have had understandable
complaints recently about how high our default fee levels are.

Changelog-Changed: Protocol: channel feerates reduced to bitcoind's "6 block ECONOMICAL" rate.

Dual-funded channels won't match the old amount check. Good news is
we're already returning the outnum so we just use that.

Rusty Russell 32d650f9df lightningd: don't abort on incorrect versions, but try to re-exec.
You still shouldn't do this (you could get some transient failures),
but at least you have a decent chance if you reinstall over a running
daemon, instead of getting confusing internal errors if message
formats have changed.

Changelog-Added: lightningd: we now try to restart if subdaemons are upgraded underneath us.

Rusty Russell 402f7f90c0 pytest: handle case where funding tx is not tx #1.
e.g. in test_closing_id we can get a spend from the first (closed) channel
in the same block as the open of the second.  Half the time, we'll choose
the wrong one as scid.

Since we turned many errors into warnings, we want our tests to fail

Michael Schmoock c8198d9820 pyln-testing: add `scids` param to `wait_for_htlcs` 2021-02-04 12:02:15 +10:30
Michael Schmoock d76ca6ed35 pyln-testing: improve `wait_for` a bit
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 :-)

Christian Decker ea67710e01 pyln: Pretty print RPC calls in the testing framework
We are printing `repr(obj)` which is not pretty-printed, hard to read,
and can't even be copied and inspected to JSON tools. We now print the
JSONified and indented calls and responses for easier debugging based
on solely the logs (useful for CI!).

Changelog-Added: pyln-testing: The RPC client will now pretty-print requests and responses to facilitate log-based debugging.

Christian Decker 4c3ee04bb7 pyln: Use a fair FS lock to throttle node startups
We were getting a couple of starvations, so we need a fair filelock. I
also wasn't too happy with the lock as is, so I hand-coded it quickly.

Should be correct, but the overall timeout will tell us how well we
are doing on CI.

Christian Decker 7e867e5ee6 pytest: Add throttler to limit load on the test system
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.
