Extended the migration process with a generic way of applying custom migration code on top of the SQL files. The implementation provides a safer way to run GO code along with the SQL migrations and possibility of rolling back the changes in case of failure to keep the database consistent. This custom GO migration is needed to extract the status from the JSON blob receipt and store it in transfers table. Other changes: - Add NULL DB value tracking to JSONBlob helper - Index status column on transfers table - Remove unnecessary panic calls - Move log_parser to wallet's common package and use to extract token identity from the logs Notes: - there is already an index on transfers table, sqlite creates one for each unique constraint therefore add only status to a new index - the planned refactoring and improvements to the database have been postponed due to time constraints. Got the time to migrate the data though, extracting it can be done later for a more efficient implementation Update status-desktop #10746
Whisper API Extension
API
shhext_getNewFilterMessages
Accepts the same input as shh_getFilterMessages.
Returns
Returns a list of whisper messages matching the specified filter. Filters out
the messages already confirmed received by shhext_confirmMessagesProcessed
Deduplication is made using the whisper envelope content and topic only, so the same content received in different whisper envelopes will be deduplicated.
shhext_confirmMessagesProcessed
Confirms whisper messages received and processed on the client side. These
messages won't appear anymore when shhext_getNewFilterMessages
is called.
Parameters
Gets a list of whisper envelopes.
shhext_post
Accepts same input as shh_post.
Returns
DATA, 32 Bytes - the envelope hash
shhext_requestMessages
Sends a request for historic messages to a mail server.
Parameters
Object- The message request object:
mailServerPeer:URL- Mail servers' enode addessfrom:QUANTITY- (optional) Lower bound of time range as unix timestamp, default is 24 hours back from nowto:QUANTITY- (optional) Upper bound of time range as unix timestamp, default is nowtopic:DATA, 4 Bytes - Regular whisper topicsymKeyID:DATA- ID of a symmetric key to authenticate to mail server, derived from mail server password
Returns
Boolean - returns true if the request was send, otherwise false.
Signals
Sends sent signal once per envelope.
{
"type": "envelope.sent",
"event": {
"hash": "0xea0b93079ed32588628f1cabbbb5ed9e4d50b7571064c2962c3853972db67790"
}
}
Sends expired signal if envelope dropped from whisper local queue before it was sent to any peer on the network.
{
"type": "envelope.expired",
"event": {
"hash": "0x754f4c12dccb14886f791abfeb77ffb86330d03d5a4ba6f37a8c21281988b69e"
