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.
We roll the `elements_add_fee_output` function and the cropping of
overallocated arrays into the `bitcoin_tx_finalize` function. This is supposed
to be the final cleanup and compaction step before a tx can be sent to bitcoin
or passed off to other daemons.
This is the cleanup promised in #3491
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.

It is ok to change the values because they are approximate anyway. Thus,
explicitly typecast to `double` to silence the warning without changing
behavior.
Changelog-None
a few things. one is that `is_in_log` returns a result rather than
enforcing a condition. so these lines all need asserts
two is that with the 'allow_deprecated_apis' option on, the python json
parser overwrites the now typed input with the later-added string
version, so the only option value present in the option key-value set is
the last, string one. the check for this has been updated to only verify
that the string version is included (i manually verified that both are
printed to the JSON message)
For messages, we use the onion but payload lengths 0 and 1 aren't special.
Create a flag to disable that logic.

This is in preparation for messages, which want this as their assocdata.
Plus, it's a bit cleaner rather than creating a tmp tal array.

Caching the `./external` directory means that any changes to
`external/Makefile` or any updates of the submodules in `./external/*`
would not be picked up and travis would run with old instances of those,
possibly "activating" such changes after weeks or months when the cache
is pruned eventually.
Changelog-None
Expands the interface to play with onions a bit more. Potentially a bit
slower due to allocations, but that's a small price to pay. It also allows us
to avoid serializing a compressed onion to `u8*` if we process it right away.
Also implements a way to decompress an onion using the devtools/onion tool
Changelog-Added: devtools: The `onion` tool can now generate, compress and decompress onions for rendez-vous routing
also: convert the stored int value from 'int' to 's64'
atoi fails silently, returning a zero. instead we use the more robust
strtoll which will allow us fail with an error.
we also make the parsing for bools stricter, only allowing plausibly
boolean values to parse.
we loosely enforce that the specified type must be one of the listed
options. you can still cause an error because we're not checking the
default value you're passing in ...
not sure if this is totally necessary, should we jsut let clightning
enforce the input?
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
We were nesting like the following:
```json
{"params": {
"rpc_command": {
"rpc_command": {
}
}
}
```
This is really excessive, so we unwrap once, and now have the following:
```json
{"params": {
"rpc_command": {
}
}
```
Still more wrapping than necessary (the method is repeated in the `params`
object), but it's getting closer.
Changelog-Deprecated: JSON-RPC: Removed double wrapping of `rpc_command` payload in `rpc_command` JSON field.

Before this patch we would only update `channel->last_tx` with the newly
proposed closure tx from the peer if the fee of the new one was lower.
In negotiations where we are at the higher end and the peer starts
lower, all peer's subsequent proposals will be higher than his initial
proposal and in this case we would never update `channel->last_tx`
and would wrongly broadcast his initial proposal at the end of the
negotiation.
Fixes https://github.com/ElementsProject/lightning/issues/3549
Changelog-Fixed: Always broadcast the latest close transaction at the end of the close fee negotiation, instead of sometimes broadcasting the peer's initial closing proposal.
Does the allocation and copying; this is useful because we can
avoid being fooled into doing giant allocations.
