Using the API's CLI to edit offers can sometimes result in add/remove messages
being received on peers in the same batch of envolopes, and these messages
are sometimes passed to the UI in (1) add, (2) remove order. This can result in
a newly edited offer being removed immediately after being added to the OfferBook
list. This change uses storage entry sequence number and storage entry payload
hash comparisons to avoid the problem.
- OfferBookListItem Added new constructor taking P2PDataStorage.ByteArray hashOfPayload,
and int sequenceNumber params. Added a new toString() method.
- OfferBook Added new checks on OfferBookListItem hashOfPayload and sequenceNumber while
determining if offer candidates should be added or removed from the UI's OfferBook List.
See OfferBook contructor's implementation of OfferBookChangedListener#onAdded and
OfferBookChangedListener#onRemoved. Added many comments explaining the add/remove rules,
and plenty of debug statements to help trace the add/remove event process.
- OfferBookService#OfferBookChangedListener Added new P2PDataStorage.ByteArray hashOfPayload,
and int sequenceNumber params to listener's onAdded and onRemoved method signatures.
Added these two new paramater values to listener.onAdded and listener.onRemoved calls.
- TakeOfferDataModel Replaced unused, old tradeManager param in offerBook.removeOffer()
with (null) P2PDataStorage.ByteArray hashOfPayload, and (-1) int sequenceNumber params.
OfferBook will remove the candidate offer as before.
- MarketAlerts Adjusted onAdded() & onRemoved listener method signatures, even though
new P2PDataStorage.ByteArray hashOfPayload, int sequenceNumber params are not used
by the implementations.
Double clicking the close ticketbutton creates two payout transactions.
This fix makes sure only one payout transaction is created for the
dispute.
Restarting the client allows for creating another refund transaction
for the dispute if needed.
Use LinkedHashSet to maintain NetworkEnvelope ordering when Connection#onBundleOfEnvelopes
calls listeners.
Connection#onBundleOfEnvelopes builds a set from an ordered list of NetworkEnvelopes,
then calls listeners during set iteration. The envelope list ordering is lost if a
HashSet is built, but maintained by switching to a LinkedHashSet.
Losing the envelope ordering becomes a problem if the peer receives a RemoveDataMessage
and an AddDataMessage in the same batch of envelopes, and relays them to listeners
in the wrong (random) order. For example, an API 'editoffer' call may result in the
edited offer being added, then immediately remove from their UI's offer book.
