Previously, in `migration25.OpenChannel`, there was a private field
`chanStatus` used to keep track of the channel status. The following
migrations, `migration26` and `migration27` also have their own
`OpenChannel` defined, with `migration26` inherited from `migration25`,
and `migration27` inherited from `migration26`. The private field
`chanStatus`, however, is NOT inherited and each of the migrations uses
its own. This is fine for reading and writing as, under the hood, the
`chanStatus` is just a `uint8` value. Because each migration has its own
fetcher and putter, it can safely access its private field to read and
write it correctly.
The issue pops up when we use the method
`migration25.FundingTxPresent()`. Because it's evaluating its channel
status using its own private field `chanStatus`, this field would always
be the default value(`ChanStatusDefault`), leading the statement
`!c.hasChanStatus(ChanStatusRestored)` to always be true. Thus a
restored channel will be mistakenly considered to have funding tx
present, causing failures in reading the channel info in the following
migrations.
We fix this by exporting the `ChanStatus` field so its value can be set
by following migrations.
This commit adds a new migration to patch the two balance fields,
`InitialLocalBalance` and `InitialRemoteBalance` for the historical
channels. Because they are not saved previously, for historical channels
prior to the revocation log PR, these fields will be empty.
This can cause an intermittent panic otherwise if bbolt remaps itself
via munmap and mmap. From bbolt's documentation:
* Byte slices returned from Bolt are only valid during a transaction.
Once the transaction has been committed or rolled back then the memory
they point to can be reused by a new page or can be unmapped from
virtual memory and you'll see an unexpected fault address panic when
accessing it.
This commit bumps the btcwallet version to the latest master branch that
contains the fixes to add Taproot related fields to a PSBT in the
FundPsbt method.
This commit fixes OOO notifications between backlog and non-backlog
events by having the non-backlog goroutines wait on a chan that
signals that backlog processing is complete.
This commit also replaces usage of the canceled atomic variable with
the cancelChan to signal that delivery of an event should no longer
occur. Atomics do not make perfect "sequence" points as the atomic
may be checked too early and the end-result of delivering to a stopped
ntfnQueue is the same. Using the cancelChan ensures that we do not
hang on sending to ntfnQueue.
Prior to this change, if SubscribeSingleInvoice or
SubscribeNotifications was called, it was possible that a state
change would never be delivered to the client. The sequence of
events would be:
- delivery of backlog events with invoice in the Open state
- invoice goes to the Accepted state, no client to notify
- client added to map
This is fixed by adding the client to the map first. However, with
this change alone it then becomes possible for notifications to be
delivered out of order. This is addressed in a following commit.
This fixes a nil-pointer-dereference that would occur if this was
called for a settled AMP invoice. Terms.PaymentPreimage is always
false for AMP invoices.
