In this commit, we update Travis to start building against the newly
released go 1.13. Additionally, we'll now utilize the new `trimpath` to
the `go build` and `go install` commands. This new flag serves to remove
all file system paths from the compiled Go executable, which will make
our binaries more reproducible.
This changes the defer function in the test for channel backups to
correctly close over the 'dave' variable.
Without this closure, the shutdownAndAssert call would attempt to
shutdown the original (non-restored) dave instead of the most recently
created (restored) dave, causing a leak of a node during tests.
In this commit, we fix a bug where if a user updates a forwarding policy to be
zero, the update will be applied to the policy correctly on-disk, but not
in-memory.
We solve this issue by having the gossiper return the list of on-disk updated
policies and passing these policies to the switch, so the switch can assume
that zero-valued fields are intentional and not just uninitialized.
Logging for the hop package is controlled via the parent htlcswitch
package. Unfortunately the parent package only controlled the
initialization, but didn't enable the logger when the log level came
in from the main lnd package.
In this commit, we ensure that the test for migration 9 uses the same
encoding/decoding functions as was present in the repo when the
migration was first added. Otherwise, the test will fail as it'll try to
use the decoding functions of master (migration 10 and onwards) rather
than the decoding function of migration 9.
Add 'Creating a wallet' section, explaining that 'lncli create' must be run
with a new instance. Also describe the password prompt and mnemonic this
command presents to the user.
In this commit, we fix an issue that was recently introduced as a result
of migration #10. The new TLV format ended up modifying the
serialization functions called in `serializePaymentAttemptInfo`.
Migration #9, also used this `serializePaymentAttemptInfo` method to
serialize the _new_ (pre TLV, but new payment attempt structure) routes
into the database during its migration. However, migration #10 failed to
copy over the existing unmodified `serializePaymentAttemptInfo` method
into the legacy serialization for migration #9. As a result, once
migration #9 was run, the routes/payments were serialized using the
_new_ format, rather than the format used for v0.7.1. This then lead to
de-serialization either failing, or causing partial payment corruption
as migration #10 was expecting the "legacy" format (no TLV info).
We fix this issue by adding a new fully enclosed
`serializePaymentAttemptInfoMigration9`method that will be used for
migration #9. Note that our tests didn't catch this, as they test the
migration in isolation, rather than in series which is how users will
encounter the migrations.
Fixes#3463.
From BOLT 04:
The writer:
- MUST include amt_to_forward and outgoing_cltv_value for every node.
- MUST include short_channel_id for every non-final node.
- MUST NOT include short_channel_id for the final node.
This commit adds an additional return value to
Stream.DecodeWithParsedTypes, which returns the set of types that were
encountered during decoding. The set will contain all known types that
were decoded, as well as unknown odd types that were ignored.
The rationale for the return value (rather than an internal member) is
so that the stream remains stateless.
This return value can be used by callers during decoding to make
assertions as to whether specific types were included in the stream.
This is need, for example, when parsing onion payloads where certain
fields must be included/omitted depending on the hop type.
The original Decode method would incur the additional performance hit of
needing to track the parsed types, so we can selectively enable this
functionality when a decoder requires it by using a helper which
conditionally tracks the parsed types.
ListenerCfg allows passing custom listeners to the main method, to be
used for the wallet unlocker and rpc server. If these are set these will
be used instead of the regular RPC listeners.
