These both allow us to reproduce the test vectors in the next patch. But
using Z_DEFAULT_COMPRESSION is a reasonable idea anyway.

Make the TLV element a simple array. This is a bit neater, in fact, and
makes the test vectors in that 557 PR work.

In fact, we always generate them, we only send them if asked. And we set
the flags to 0 if not --enable-experimental-features, so we never send in
that case.
Generating checksums involves pulling the channel_update from the
gossip_store, which is suboptimal: there's a FIXME to store the
checksum in memory.

We're about to use the for gossip extended info too, which *don't* put
the encoding byte at the beginning of the data stream. So this removes
some "scids" from function names and separates out the "prepend a byte"
case from the "external encoding_type" case.

These indicate what fields we are to return. If there's now TLV, or we
haven't got --enable-experimental-features, it's set to all 1s so behaviour
is unchanged.

We haven't touched the readme for quite some time, just randomly added to it,
and it's starting to show. This is my attempt at cleaning it up a bit (more to
come):
- No longer discourage users from running on mainnet, we're way beyond that
point.
- No longer instruct users to build from source, when we have real binary
releases, on the PPA, the releases page and the docker images.
- Cut down on the docker specific instructions, they are taking a lot of room
when only a minority will likely run them that way
- Generally make the README more of a dispatch for more in-depth
documentation rather than trying to address everything right on the
front-page.
- Add a bit of context about running on top of a pruned node

We ignored this before, which meant that the DEVELOPER-mode check that we
delete the correct record didn't check that it wasn't already deleted.

`close` takes two optional arguments: `force` and `timeout`.
`timeout` doesn't timeout the close (there's no way to do that), just
the JSON call. `force` (default `false`) if set, means we unilaterally
close at the timeout, instead of just failing.
Timing out JSON calls is generally deprecated: that's the job of the
client. And the semantics of this are confusing, even to me! A
better API is a timeout which, if non-zero, is the time at which we
give up and unilaterally close.
The transition code is awkward, but we'll manage for the three
releases until we can remove it.
The new defaults are to unilaterally close after 48 hours.
Fixes: #2791

We're about to change the API, so this makes the tests still work
across the transition (and, as a bonus, tests our backwards compat
shim).

This was the initial issue that was addressed by #2756 and now we just test
that all is working as expected.

If we were to just insert filtered blocks in the range that we will scan later
we'd be hitting the uniqueness constraints later.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Instead of allowing all calls to `getfilteredblock` to be scheduled on the
`bitcoind` queue right away we instead add them in a separate queue, and
process a single call at a time. This limits the concurrency and avoids
thrashing `bitcoind`. At the same time we dispatch incoming results back to
all calls that were queued for that particular blockheight, reducing the
overall number of calls and an increase in overall speed.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We will be calling the callback out of order once we fan out the results of a
single lookip to multiple calls, so being sure that everything is allocated
ahead of time is necessary.

Since we now check all P2WSH outputs in a block, this is getting quite a
common occurence, so logging just produces lots of noise.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This will eventually replace the multi-step `getblockhash` + `getblock` +
`gettxout` mechanism, and return entire filtered blocks which can be added to
the DB, and represent the full set of P2WSH UTXOs.

This is just the test that we use to verify block backfilling below the wallet

@renepickhardt has a shell script we broke. While we still produce
perfectly valid JSON, we should not gratuitously change tool output.
Plus, I prefer the missing space before the ':'.

The helpme plugin is more comprensive, but this at least connects to a
few random nodes, and doesn't require python libraries in path or anything.
I selected the nodes from helpme.py, eliminating ones I couldn't reach.

This test is spawning 100 nodes concurrently, which is a lot even when not
running with `valgrind`, especially when executing tests in parallel.

This was causing `--help` to fail if we already had a `lightningd` running
with the same `--lightning-dir`.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This is a followup to #2892. Since we now attempt to lock the PID file before
starting plugins we need to make sure that we actually use a unique lightning
directory for anything that attempts to call `--help`. If not we may be
conflicting with a `lightningd` that is running against that directory.
Notice that this still means that we will be unable to call `--help` on
`lightningd` if we have a running instance, but isolation in this case is
good, otherwise we'd be reading the default config anyway.
