This commit replaces aead’s chacha20 library with the official golang
implementation. We should see a bit of a performance increase on amd64
as the assembly for the library uses the SIMD AVX2 instructions in the
inner loop. In the future assembly will be written for other platforms,
so we’ll see a performance increase across the board.
Fixes#146.
This commit removes all instances of the fastsha256 library and
replaces it with the sha256 library in the standard library. This
change should see a number of performance improvements as the standard
library has highly optimized assembly instructions with use vectorized
instructions as the platform supports.
Add check that vendor directory is installed and if not we should run
glide install, also if additional flag '-i' is specified than we will
reinstall dependencies.
This commit removes a number of sleeps from the set of current
integration tests by replacing them with a synchronous (w/ a timeout)
block until one or many channels are detected as being open within the
network.
As a result, the tests are now more robust, many flakes have been
eliminated, and finally this shaves a few second off of the integration
testing runs.
This commit fixes a bug which was originally introduced when the
topology notifications were added to the channel router. The issue was
that a pointer to the loop-scope range variable was being passed into
the goroutine which dispatches the notification rather than the value
itself. It seems that the memory location is re-used between range
iterations causing the same client to receive _all_ the notifications.
This bug is fixed by passing a copy of the client struct rather than a
pointer to the range variable.
In the process, we also add some additional debug logging messages, and
remove the Curve parameter from any public keys involved in a
notification so the pretty print properly.
This commit modifies the two newly added network announcement hook stop
be at the lightningNode level rather than on the level of the entire
test framework. With this, callers are now able to better utilize the
newly added RPC’s since they can target particular peers and wait for
network messages to be processed rather then depending on a single node
(Alice) for information about the announcements propagated within the
network.
This commit adds the ability for test authors using the integration
testing framework to hook into real-time notifications for
network-level announcements concerning channel openings, closings, and
updates. With this commit we should be able to eliminate a number of
the sleeps within the test framework with synchronous calls (time outs)
to the new methods added in this PR.
This commit implements the new server-side streaming RPC call within
the current default implementation of the RPC server. With this, the
new functionality can now be used within the integration tests to
achieve a greater degree of synchronization in the tests. As a result,
we should be able to eliminate many of the sleeps lingering within the
tests.
This commit modifies the `ChannelEdgeUpdate` struct to include the
channel point itself within the notifications. Such a change improves
the notificaiton experience for callers as it allows them to filter out
update notifications based on a familiar object within the codebase: a
channel point.
If a forceClose happens and the to-self output is below the dust value,
then that output will be non-existant in the commitment transaction.
UtxoNursery now handles that case by checking to see if the accompanying
selfOutPutSignDescriptor is nil. If it is nil, then it will ignore it.
If the value of the to-local output is below the dust limit, the
ForceCloseSummary should not include a sign descriptor for this output.
We also find the proper to-self output by looking for the expected public
key script and not assume that no HTLC outputs exist.
Currently non-HTLC outputs will be accepted in the commitment
transaction as long as it is non-zero. We change this by not allowing
outputs with a value lower than the dust limit. The value of such
an output will go towards transaction fees.
This commit modifies the glide target for btcwallet to pin against a
particular commit that will attempt to auto-reconnect to the btcd node
in the case of a websockets connection drop.
This commit adds a new field to the ListChannels RPC command which
indicates if the peer is currently online or not. This is useful as
UI’s will be able to use this information to communicate the
availability of each channel to an end user.
This commit adds some new functionality to the channel router: the
ability to dispatch notification to registered clients upon either a
channel being closed, a new node appearing, or an exiting client being
updated or opened for the first time.
With this change, the integration tests will now be able to eliminate
most of the sleep as we gain a new syntonization point into the
propagation of information within the test network. Additionally, this
also paves the way for client side software to dynamically visualize
the channel graph in real-time as nodes+channels are updated.
This commit modifies the path finding routines to properly use the new
channel edge related API exposed by the database. Additionally, a new
type `ChannelHop` has been introduced which couples an edges routing
policy with the capacity and origin chain of the channel.
This commit modifies the ChannelUpdateAnnouncement to rename the Expiry
variable instead of TimeLockDelta as that is more descriptive of the
purpose of the attribute itself.
This commit updates all the RPC’s that deal with querying for data
stored within the graph to the latest version of the public API for the
graph itself.
This commit alters the return value of PrunedGraph to me a bit more
useful: the function now returns all the channels that were closed when
processing the block (slice of spent outpoints). With this information,
callers gain greater visibility into exactly which channels were
closed. This can be used in higher levels to present detailed summaries
of how blocks affect closed channels.
This commit splits the prior ChannelEdge struct into two distinct
structs: ChannelEdgeInfo and ChannelEdgePolicy. The info structs stores
the _full_ information that was used to advertise the channel, while
the policy struct contains the information that’s needed in order to
use the information for routing purposes.
With this split we can eliminate a number of hacks within the rest of
the codebase that were added as a result of data unavailability if one
or neither edge was present.
Finally a bit of field renaming has taken place (Exipiry ->
TimeLockDelta), etc.
This commit fixes a minor bug that was introduced with the latest PR
that made specifying the —push_amt flag when opening a channel
mandatory. The fix is simple, turn the switch statement into an
if/else, which makes the —push_amt flag optional once again.
This commit updates the command line help for several commands within
cmd/lncli to be more uniform, and also use the proper attributes within
the urfave/cli project. Additionally, in several areas cli.Int was using
used instead of cli.Int64 when parsing satoshis. This oversight has been
rectified by modifying all incorrect occurrences.
Finally, this commit, as its central contribution, adds the ability to mix
and match positional arguments with key-word arguments for several
commands! The following commands can now be used with either only
positional arguments, only key-word arguments, or a mix of both when
applicable:
* openchannel
* closechannel
* sendpayment
* getnodeinfo
* getchaninfo
* newaddress
* sendcoins
* sendmany
* connect
* addinvoice
* lookupinvoice
* queryroute
The set of changes outlined above should make command line tinkering with
`lnd` a bit more streamlined, yet still very flexible.
