`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 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.
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.
Needs to initialize global now. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Previously, returned null if a scriptpubkey was not Segwit; now handles encoding to Base58 for other types.
If a 'upfront_shutdown_script' was specified, show the address + scriptpubky in `listpeers` Changelog-added: JSON API: `listpeers` channels now include `close_to` and `close_to_addr` iff a `close_to` address was specified at channel open
--dev-force-tmp-channel-id flag takes a 64-character hex string to use as the temporary channel id. Useful for spec tests [ Fixed crash in non-DEVELOPER mode --RR ] Changelog-None

We add routines to decode the expected fields from both legacy and tlv hop formats. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-changed: JSON API: `htlc_accepted` hook has `type` (currently `legacy` or `tlv`) and other fields directly inside `onion`. Changelog-deprecated: JSON API: `htlc_accepted` hook `per_hop_v0` object deprecated, as is `short_channel_id` for the final hop.
We keep the feature bitmap on disk, so we cache this in the struct explicitly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Default is legacy. If we have future styles, new strings can be defined, but for now it's "tlv" or "legacy". Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
For legacy, they were the same, but for TLV we care whether it's the final hop or not. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

It really, really doesn't matter. But we were dramatically reducing our view of the network: In my gossip_store (mainnet): channel_announcement: 30349 channel_update: 55119 node_announcment: 1783 Changelog-Fixed: No longer discard most node_announcements (fixes ElementsProject#3194) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
…bolt11. The pay plugin has been supplying the bolt11 string since 0.7.0, so only ancient "pay" commands would be omitted by this change. You can create a no-bolt11 "sendpay" manually, but then you'll find it in 'listsendpays'. Changelog-Removed: JSON: `listpays` won't shown payments made via sendpay without a bolt11 string, or before 0.7.0. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This won't usually be visible to the end-user, since the pay plugin doesn't do multi-part yet (and mpp requires EXPERIMENTAL_FEATURES), but we're ready once it does. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

It makes sense, and it's been proposed for addition to the spec to broad agreement: lightning/bolts#712 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

We only tested exactly two equal-size payments; indeed, our finalhop test was backwards. We only complain if the final hop pays more than twice msat (technically, this test is still too loose for mpp: the spec says we should sum to the exact amount).

Indeed, if you waitsendpay without specifying a partid, you are waiting for 0, which may not exist. Clarify the error msg. Reported-by: @t-bast Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This uses the same state machine as HTLCs, but they're only ever added, not removed. Since we can only have one in each state, we use a simple array; mostly NULL. We could make this more space-efficient by folding everything into the first 5 states, but that would be more complex than just using the identical state machine. One subtlety: we don't send uncommitted fee_states over the wire. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
And also move it to initial_channel, so we can use it there. This saves churn in the next patch. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
…mitment. The `channel_got_commitsig` we send the lightningd also implies we sent the revoke_and_ack, as an optimization. It doesn't currently matter, since channel_sending_revoke_and_ack doesn't do anything important to the state, but that changes once we start uploading the entire fee_states. So now we move our state machine *before* sending to lightningd, in preparation for sending fee_states too. Unfortunately, we need to marshall the info to send before we increment the state, as lightningd expects that. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is an intermediary step: we still don't save it to the database, but we do use the fee_states struct to track it internally. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
These used to be necessary as we could have feerate changes which we couldn't track: now we do, we don't need these flags. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The upgrade here is a bit tricky: we map the two values into the feerate_state. This is trivial if they're both the same, but if they're different we don't know exactly what state they're in (this being the source of the bug!). So, we assume that the have received the update and not acked it, as that would be the normal case. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is the final step: we pass the complete fee_states to and from channeld. Changelog-Fixed: "Bad commitment signature" closing channels when we sent back-to-back update_fee messages across multiple reconnects. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The norm for channels is a 1% reserve. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Otherwise tests for hold_invoice fail on Travis (they use 180 / 2 as the timeout, and we free it after 70 seconds). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Thanks to @t-bast, who made this possible by interop testing with Eclair! Changelog-Added: Protocol: can now send and receive TLV-style onion messages. Changelog-Added: Protocol: can now send and receive BOLT11 payment_secrets. Changelog-Added: Protocol: can now receive basic multi-part payments. Changelog-Added: RPC: low-level commands sendpay and waitsendpay can now be used to manually send multi-part payments. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We still close the channel if we *send* an error, but we seem to have hit another case where LND sends an error which seems transient, so this will make a best-effort attempt to preserve our channel in that case. Some test have to be modified, since they don't terminate as they did previously :( Changelog-Changed: quirks: We'll now reconnect and retry if we get an error on an established channel. This works around lnd sending error messages that may be non-fatal. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This matters now we have an array in tlv_init_tlvs! We were overallocating in fromwire by 32x! Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
