This commit adds basic syncing capabilities with peers if they are both
online.
It updates the work done on MVDS, but I decided to create the code in
status-go instead, since it's very tight to the application (similarly
the code that was the inspiration for mvds, bramble, is all tight
together at the database level).
I reused parts of the protobufs.
The flow is:
1) An OFFER message is sent periodically with a bunch of message-ids and
group-ids.
2) Anyone can REQUEST some of those messages if not present in their
database.
3) The peer will then send over those messages.
It's disabled by default, but I am planning to add a way to set up the
flags.
* chore(upgradeSQLCipher): Upgrading SQLCipher to version 5.4.5
Changes:
### github.com/mutecomm/go-sqlcipher
1. The improved crypto argorighms from go-sqlcipher v3 are merged in v4
Tags:
v4.4.2-status.1 - merge `burn_stack` improvement
v4.4.2-status.2 - merge `SHA1` improvement
v4.4.2-status.4- merge 'AES' improvement
2. Fixed `go-sqlcipher` to support v3 database in compatibility mode (`sqlcipher` already supports this) (Tag: v4.4.2-status.3)
3. Upgrade `sqlcipher` to v5.4.5 (Tag: v4.5.4-status.1)
### github.com/status-im/migrate/v4
1. Upgrade `go-sqlcipher` version in `github.com/status-im/migrate/v4`
### status-go
1. Upgrade `go-sqlcipher` and `migrate` modules in status-go
2. Configure the DB connections to open the DB in v3 compatibility mode
* chore(upgradeSQLCipher): Use sqlcipher v3 configuration to encrypt a plain text database
* chore(upgradeSQLCipher): Scanning NULL BLOB value should return nil
Fixing failing tests: TestSyncDeviceSuite/TestPairingSyncDeviceClientAsReceiver; TestSyncDeviceSuite/TestPairingSyncDeviceClientAsSender
Considering the following configuration:
1. Table with BLOB column has 1 NULL value
2. Query the value
3. Rows.Scan(&dest sql.NullString)
Expected: dest.Valid == false; dest.String == nil
Actual: dest.Valid == true; dest.String == ""
* chore: Bump go-sqlcipher version to include NULL BLOB fix
