A CONSERVATIVE/3 target for them.
Some noisy changes to the tests as we had to update the estimatesmartfee
mock.
Changelog-Changed: We now use a higher feerate for resolving onchain HTLCs and for penalty transactions
So we can't tell people they should use amount, until v0.8.2 is
released. Another 6 months before we can deprecated the 'satoshi'
field here :(
Fixes: d149ba2f3a
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: JSON: `fundchannel_start` returns `amount` even when deprecated APIs are enabled.
Changelog-Deprecated: JSON: `fundchannel_start` `satoshi` field really deprecated now (use `amount`).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Removed: JSON: `fundchannel` and `fundchannel_start` `satoshi` parameter removed (renamed to `amount` in 0.7.3).
This is a common thing to do, so create a macro.
Unfortunately, it still needs the type arg, because the paramter may
be const, and the return cannot be, and C doesn't have a general
"(-const)" cast.

Before this patch we used to send `double`s over the wire by just
copying them. This is not portable because the internal represenation
of a `double` is implementation specific.
Instead of this, multiply any floating-point numbers that come from
the outside (e.g. JSONs) by 1 million and round them to integers when
handling them.
* Introduce a new param_millionths() that expects a floating-point
number and returns it multipled by 1000000 as an integer.
* Replace param_double() and param_percent() with param_millionths()
* Previously the riskfactor would be allowed to be negative, which must
have been unintentional. This patch changes that to require a
non-negative number.
Changelog-None
Spark does this, for example:
{"method":"pay","params":["lnbc..."],"id":22}
Which doesn't have a jsonrpc field. The result is that the command
doesn't terminate, there is nothing in the logs, stderr contains
"pay: JSON-RPC message does not contain "jsonrpc" field", and
from then on "Unknown command 'pay'".

We are going to initialize a plugin before its creation, so log as
UNUSUAL instead.
Also, `pay` and `fundchannel` inits are using rpc_delve(), so we need to
io_new_conn() (which sets the socket as non blocking) after calling the
plugin's init.
This is also taken and adapted from lightningd/bitcoind.
The call to 'getblockchaininfo' is replaced by 'echo' as we don't
make use of the result and the former can sometimes be slow (e.g. on
IBD).
Most is taken from lightningd/bitcoind and adapted. This currently
exposes 5 commands:
- `getchaininfo`, currently called at startup to check the network and
whether we are on IBD.
- `getrawblockbyheight`, which basically does the `getblockhash` +
`getblock` trick.
- `getfeerate`
- `sendrawtransaction`
- `getutxout`, used to gather infos about an output and currently used by
`getfilteredblock` in `lightningd/bitcoind`.
We don't take the callback result into account, so it can better be void.
Having a general callback parameter is handy, because for bcli we want
to pass it the struct bcli.
As a separated commit because it was pre-existent (changelog + xfail test).
This also fix a logical problem in lightningd/plugin_control: we were
assuming a plugin started with 'plugin start' but which did not comport
a 'dynamic' entry in its manifest to be dynamic, though it should have
been treated as static.
Changelog-fixed: plugins: Dynamic C plugins can now be managed when lightningd is up
This adds helpers to start and send a jsonrpc request using json_stream
in order to benefit from the helpers.
This then simplifies existing plugins RPC requests by using json_stream
helpers.
This pass to json_stream helpers for commands outputs, but keeps
compatibility with existing plugins which use jout as of now, by not
starting/closing the "result"/"error" objects.
Now we have streams and a global object, we can use them for io_plans.
This makes the logic closer from lightningd/plugin (it has been mostly
stolen from here), and simplifies the main.
This also allows plugins to use io_plans (thanks to the io_loop) for
asynchronous connections.
This commit only handle incoming commands.
Now that we have json_stream in common/, we can move all the related
helpers from lightningd/json to common/json. This way everyone can
benefit of them (including libplugin, the plugins themselves,
potentially lightning-cli), not lightningd alone!
Note that the Makefile of the common/test/ had to be modified, because
the new helpers make use of common/wireaddr... Which turns out to
\#include <lightingd/lightningd.h> ! So we couldnt just include the .c
and add mocks if we redefined some structs (hello run-param).
GCC 10 defaults to `-fno-common`. no longer automatically sharing
global variable definitions, which makes it important to define
them in only one place (otherwise there will be duplicate definition
errors). Add `extern` qualifiers where (I think) is the best place for
them.
Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.
To resolve this:
* Introduce an error code type with a known size:
`typedef s32 errcode_t`.
* Change all error code macros to constants of type `errcode_t`.
Constants also play better with gdb - it would visualize the name of
the constant instead of the numeric value.
* Change all functions that take error codes to take the new type
`errcode_t` instead of `int`.
* Introduce towire / fromwire functions to send / receive the newly added
type `errcode_t` and use it instead of `towire_int()`.
In addition:
* Remove the now unneeded `towire_int()`.
* Replace a hardcoded error code `-2` with a new constant
`INVOICE_EXPIRED_DURING_WAIT` (903).
Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2
Changelog-Fixed: Detect a previously non-permanent error (`final_cltv_too_soon`) that has been merged into a permanent error (`incorrect_or_unknown_payment_details`), and retry that failure case in `pay`.
it's that time of year (merry xmas!)
enables the ability to push_msat on fundchannel
Changelog-Added: RPC: `fundchannel` and `fundchannel_start` can now accept an optional parameter, `push_msat`, which will gift that amount of satoshis to the peer at channel open.
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.

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.
