For security reasons, browsers are limited in the header fields they can
send when opening a WebSocket connection. Specifically, the macaroon
cannot be sent in the Grpc-Metadata-Macaroon header field as that would
be possible for normal REST requests. Instead we only have the special
field "Sec-Websocket-Protocol" that can be used to transport custom
data. We allow the macaroon to be sent there and transform it into a
proper header field for the target request.
According to the recent discussion `noseedbackup` is not deprecated.
This change clarifies the message about deprecation.
Also fixes a typo.
Closes#4499
This commit extends invoice garbage collection to also remove invoices
which are canceled when LND is already up and running. When the option
GcCanceledInvoicesOnTheFly is false (default) then invoices are kept and
the behavior is unchanged.
This commit extends channeldb with the DeleteInvoices call which is when
passed a slice of delete references will attempt to delete the invoices
pointed to by the references and also clean up all our invoice indexes.
This commit adds channeldb.ScanInvoices to scan through all invoices in
the database. The new call will also replace the already existing
channeldb.FetchAllInvoicesWithPaymentHash call in preparation to collect
invoices we'd like to delete and watch for expiry in one scan in later
commits.
We use the event timestamp of a forwarding event as its primary storage
key. On systems with a bad clock resolution this can lead to collisions
of the events if some of the timestamps are identical. We fix this
problem by shifting the timestamps on the nanosecond level until only
unique values remain.
This commit adds an integration test that runs on a Windows virtual
machine on Travis. The tests run inside of a "Git Bash" environment
which supports the same command line syntax as a proper bash but doesn't
have all the tooling installed. Some tools also behave differently on
Windows. Therefore we also have to simplify the command to upload the
logs to termbin and remove the upload to file.io on Windows because both
the find and tar command don't work as expected.
In this commit, unify the old and new values for `sync-freelist`, and
also ensure that we don't break behavior for any users that're using the
_old_ value.
To do this, we first rename what was `--db.bolt.no-sync-freelist`, to
`--db.bolt.sync-freelist`. This gets rid of the negation on the config
level, and lets us override that value if the user is specifying the
legacy config option.
In the future, we'll deprecate the old config option, in favor of the
new DB scoped option.
This value actually isn't read anywhere, since it's no longer used.
Instead, `cfg.Db.Bolt.NoSyncFreeList` is what's evaluated when we go to
open the DB.
This commit extends compatibility with the bbolt kvdb implementation,
which returns ErrIncompatibleValue in case of a bucket/value key
collision. Furthermore the commit also adds an extra precondition to the
transaction when a key doesn't exist. This is needed as we fix reads to
a snapshot revision and other writers may commit the key otherwise.
This commit includes a regression test that checks that we remember
to restore updates that we sent to the peer but they haven't sent
us a signature for yet.
This fixes a long-standing force close bug. When we receive a
revocation, store the updates that the remote should sign next under
a new database key. Previously, these were not persisted which would
lead to force closure.
Follow up labelling of external transactions with labels for the
transaction types we create within lnd. Since these labels will live
a life of string matching, a version number and rigid format is added
so that string matching is less painful. We start out with channel ID,
where available, and a transaction "type". External labels, added in a
previous PR, are not updated to this new versioned label because they
are not lnd-initiated transactions. Label matching can check this case,
then check for a version number.
This commit removes the lock set which was used to only add bucket keys
to the tx predicate while also bumping their mod version.
This was useful to reduce the size of the compare set but wasn't useful
to reduce contention as top level buckets were always in the lock set.
This commit moves makeTestDB to db.go and exports it so that we'll be
able to use this function in other unit tests to make them testable with
etcd if needed.
This commit changes the key derivation algo we use to emulate buckets
similar to bbolt. The issue with prefixing keys with either a bucket or
a value prefix is that the cursor couldn't effectively iterate trough
all keys in a bucket, as it skipped the bucket keys.
While there are multiple ways to fix that issue (eg. two pointers,
iterating value keys then bucket keys, etc), the cleanest is to instead
of prefixes in keys we use a postfix indicating whether a key is a
bucket or a value. This also simplifies all operations where we
(recursively) iterate a bucket and is equivalent with the prefixing key
derivation with the addition that bucket and value keys are now
continous.
Previously, we could sign a pending commitment for the remote party,
disconnect, and not restore these signed remote updates as having been
removed at the pending commitment height. This commit fixes that to
look up whether the update under the unsigned acked updates key is
present on the pending commitment or not and appropriately set
the remove commit heights.
