* Rework plugin loading:
We now require the plugin to supply a manifest entry for the "Main-Class" attribute, this is used to load the plugin without doing illegal reflection operations. We also get rid of the dependency org.clapper.classutil
The term "non-segwit UTXOs" appears in the error message that results from having such outputs in your bitcoin core wallet, and now the readme contains that same term and the solution to make troubleshooting easier.
We already have Java 7 (for Android) and Java 11. Supporting Java 8
would require crossbuilding, which we are not doing (two recent PRs
broke the build on Java 8).
* Add scoverage-maven-plugin dependency
* Update travis build to generate a scoverage report
* Add custom codecov configuration to have nice PR comments
* Add badge for test coverage in readme
* Backup running channel database when needed
Every time our channel database needs to be persisted, we create a backup which is always
safe to copy even when the system is busy.
* Upgrade sqlite-jdbc to 3.27.2.1
* BackupHandler: use a specific bounded mailbox
BackupHandler is now private, users have to call BackupHandler.props() which always
specifies our custom bounded maibox.
* BackupHandler: use a specific threadpool with a single thread
* Add backup notification script
Once a new backup has been created, call an optional user defined script.
Port the existing API functionalities over a new structure of HTTP endpoints, with the biggest difference being the usage of **named parameters** for the requests (responses are unchanged). RPC methods have become endpoints and the parameters for each are now passed via form-params (clients must use the header "Content-Type" : "multipart/form-data"), this allows for a clearer interpretation of the parameters and results in more elegant parsing code on the server side. It is possible to still use the old API version via a configuration key.
Old API can be used by setting `eclair.api.use-old-api=true`.
* Upgrade to JDK11
Eclair can be built and used on Oracle JDK 1.8 or OpenJDK 11.
JavaFX is now embedded in eclair-node-gui and does not need to be installed separately.
* Install: update java download links
OpenJDK 11 is now our recommendation. Tell users to download java from https://jdk.java.net/11
* README: Rewrite installation instructions
* Improved amounts readability (fixes#542) and added the Bits unit
denomination in the documentation
* Improved channel panel UI layout
* Added a confirmation dialog when closing a channel, with a short summary
of the channel to be closed
The balance bar has been shrunk in size so that it should not be mistaken as
a separator element between channels. The channel's balance, capacity and
peer node id are now more visible. Also added the short channel id to the
channel's pane.
fixes#690
* Added node's aggregated balance in the status bar
fixes#775
* Support searching backward from the target
* Use the amount+fees with testing for min/max htlc value of edges
* Build the adjacency list graph with incoming edges instead of outgoing
* Make sure we don't find routes longer than the max allowed by the spec
* Remove default amount msat, enhance 'findroute' API
* Optimize tests for ignored edges in Dijkstra
* Enhance test for max route length, fix the length to 20 channels
* Add test for routing to a target that is not in the graph (assisted routes)
* Add instructions for Bitcoin Core 0.17.0 [ci skip]
Bitcoin Core 0.17.0 deprecates the `signrawtransaction` RPC call, which will be removed in version 0.18.0, you need to enable this call if you want your eclair node to use a 0.1.70 node.
* README: add an example of how to use the new bitcoin.conf sections [ci skip]
Added a new `AuditDb` which keeps tracks of:
- every single payment (received/sent/relayed)
- every single network fee paid to the miners (funding, closing, and all commit/htlc transactions)
Note that network fees are considered paid when the corresponding tx has reached `min_depth`, it makes sense and allows us to compute the fee in one single place in the `CLOSING` handler. There is an exception for the funding tx, for which we consider the fee paid when the tx has successfully been published to the network. It simplifies the implementation and the tradeoff seems acceptable.
Three new functions have been added to the json-rpc api:
- `audit`: returns all individual payments, with optional filtering on timestamp.
- `networkfees`: returns every single fee paid to the miners, by type (`funding`, `mutual`, `revoked-commit`, etc.) and by channel, with optional filtering on timestamp.
- `channelstats`: maybe the most useful method; it returns a number of information per channel, including the `relayFee` (earned) and the `networkFee` (paid).
The `channels` method now returns details information about channels. It makes it far easier to compute aggregate information about channels using the command line.
Also added a new `ChannelFailed` event that allows e.g. the mobile app to know why a channel got closed.
* add api call to update channel relay fees
* fixed bug in GUI, as channel can had different fees in each direction!
* fire transitions on `TickRefreshChannelUpdate` (fixes#621)
* make router publish `channel_update`s on startup
* (gui) Channel info fees are now options and case where channels have no known fees data is now properly handled.
* add support for mainnet final pubkeyscript
* electrum: add addresses of electrumx servers on mainnet
* electrum: use chain hash to compute addresses and HD key paths
* store db files in a subdirectory of datadir
* add a 'catchall' around deserialization
* use chain-specific key derivation paths for channel keys
* fixed intermittently failing test (we were comparing timestamps...)
* parameters:
- set default `router-broadcast-interval` to 60s
- set default `mindepth-blocks` to 3 blocks
- removed deprecated setting `router-validate-interval`
- reduce fees: block target 1->2
- reduce `MIN_CLTV_EXPIRY` from 9 to 7
Default value in BOLT11 was indeed 9 blocks, but the absolute minimum
value computed in BOLT2 is 7 blocks.
- remove unused `default-feerate-per-kb`
- set default `max-htlc-value-in-flight-msat`=10mBTC
- set default `max-to-local-delay-blocks` to 2000 blocks
* Update README with instructions for mainnet
* Upgrade to bitcoin-lib 0.9.15 (#516)
* use fees from provider, not default ones
* Add api call to check invoice/paymentRequest and return details in json
* Adding in API call to allow user to check route before making send call
* Added a serializer for route response
* Update README to include new checkinvoice and findroute API calls
As soon as we receive a valid closing signature, we will publish the
resulting closing tx instead of our commitment tx if we need to
immediately close the channel (before end of negotiation, e.g. in case
of errors, or in case the counterparty goes OFFLINE).
When the closing signature didn't correspond to one we sent ourselves, we
weren't properly recognizing the publishing tx and went into
`ERR_INFORMATION_LEAK` state.
CMD_CLOSE is now split it to commands:
* `CMD_CLOSE`: this command will succeed only if the current
channel state is in NORMAL, or if the channel hasn't yet been created.
* `CMD_FORCECLOSE`: the channel will publish its current local
commitment (or its best signed closing tx if it has one).
Using `CMD_FORCECLOSE` is more expensive and it incurs a delay before
funds are spendable, but this can be useful in some situations, for
example when the counterparty isn't responding anymore.
Added a new `forceclose` method to the API and a force close button in
the GUI.
The Bitcoin Core `addwitnessaddress` rpc command is deprecated in version 0.16.0. Thus, the example `bitcoin.conf` needs to be extended to with the option `deprecatedrpc=addwitnessaddress`.
Without this change, Eclair will not be able to open new channels and the following error message will be written to eclair.log:
```
WARN akka.actor.OneForOneStrategy akka://default/user/$h/switchboard/peer-0390b6fbf04dd277955ce454c87b270d3c910fa96ef3d78afa4bf17d3b733fb877 - addwitnessaddress is deprecated and will be fully removed in v0.17. To use addwitnessaddress in v0.16, restart bitcoind with -deprecatedrpc=addwitnessaddress. Projects should transition to using the address_type argument of getnewaddress, or option -addresstype=[bech32|p2sh-segwit] instead. (code: -32)
```
* moved CoinUtils to eclair-core to expose conversion methods
Parsing and converting string amount to BtcAmount objects, and
displaying BtcAmount as well formatted string is a common use case.
Methods that were developed for the gui module should be exposed from
eclair-core so that they can be reused elsewhere.
* increased timeouts in integration tests
* have bitcoin wallet and watcher use a separate client
* return more information on channel opening
* removed `storedChannels` from `Peer` constructor
1) so that they can be garbage-collected
2) that was a memory leak because closed channel would stay forever
* OpenChannel now accepts a feerate param for the funding Tx
User should be able to override the fee rate of the funding tx that he
sends when he opens a channel. This custom fee is entered as a fee rate
in satoshi per byte, and converted to a fee rate per kw.
The default value of this fee rate does not change, and still aims for
the funding tx to be included in a block within the next 6 blocks,
estimation which is made through the FeeProvider class.
* reworked payment events
and made sure we send events even when `PaymentLifecycle` disappeared, e.g.
when we restart right after having sent a payment.
* (gui) Added funding tx id to channel panel
fixes#335
* (gui) close channel button hidden when CLOSING or CLOSED
fixes#332
* (gui) User can define a preferred display unit
On startup FxApp reads the configuration from `eclair.conf` and sets
a unit to which all the amounts in the UI must be converted.
This unit is a CoinUnit object. Only `sat`, `mbtc` and `btc` are accepted.
`msat` is not accepted because it's an internal accounting unit which
should be invisible to the user. Default unit is `btc`
The gui does not expose any ui feature to update this unit at runtime.
* (gui) Notification message wraps and can now be copied
Notification message should be readable especially when an error occurs.
The message can be copied for easier issue reporting.
* Payment attempts is limited to 1
* (gui) consistent order in status bar contextual actions
* (gui) fixed unit parsing
* (gui) added menu shortcuts
fixes#347
* Revert "Payment attempts is limited to 1"
This reverts commit 1f4168aacb.
* (gui) BtcAmount are convertible to raw big decimal without loss
Fix issue where the decimal part of a BtcAmount could be lost.
Millisatoshi is now accepted as a user preferred unit.
* Set a minimum htlc amount of 1 mSat by default
By default, the node configuration should be permissive and accept low
value payments. It is up to the node admin to set up a restrictive
configuration if he needs it.
* (gui) port in node uri is optional
* (gui) added reactive errors in open channel window
* (gui) format max pr amount to user preferred unit
* (gui) Payment Request QR should be uppercased
see #375
* (gui) added a conf for the gui module
* Added eclair.gui.unit option in README
* reworked eclair-cli
* API is disabled by default, disabled CORS and require basic auth password
* better error handling
* Fixed latest version in README
* Increased connection timeout to 15s in electrum client test
* Rgb in NodeAnnouncement is now a Color object
Makes the color field more practical to handle and enable finer
serialization with a more readable code.
allnodes command in api now exports a list with node announcements.
* Added api call to list all the channels updates
This call can also filter the channels for a given nodeId
This fixes#344.
