Controller batches SysTray updates into one per second.
Block generation only allowed by Controller is clock
known to be accurate. ('not sure' stops generation).
NTP MAX_STDDEV increased from 25ms to 125ms to cater
for poorly connected nodes.
Controller sends peers list over outbound peer connections,
requests peers list from inbound peer connections.
When peer handshake completes, Network & Controller only send
initial messages over outbound peer connections.
This is to fix HEIGHT_V2 messages being processed out-of-order
breaking handshaking, as indicated by log entries like:
2019-07-26 16:16:35 DEBUG Network:702 - Unexpected HEIGHT_V2 message from xx.xxx.xx.xx:pppp, expected PROOF
2019-07-26 16:16:35 DEBUG Network:840 - Handshake completed with peer xx.xxx.xx.xx:pppp
Increased connection failure backoff from 1 minute to 5 minutes,
as handshake timeout is 1 minute and then nodes would immediately reconnect.
Changed default NTP servers from asia to cn.

Qora2
To use:
- Use maven to fetch dependencies.
- Build project.
- Build v1feeder.jar as a fatjar using src/v1feeder.java as the main class
- Fire up an old-gen Qora node.
- Use
v1feeder.jarto migrate old Qora blocks to DB:
java -jar v1feeder.jar qora-v1-node-ip
You should now be able to run all the JUnit tests.
You can also examine the migrated database using HSQLDB's "sqltool".
It's a good idea to install "rlwrap" (ReadLine wrapper) too as sqltool doesn't support command history/editing!
Typical command line for sqltool would be:
rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC} qora
${HSQLDB_JAR} contains pathname to where Maven downloaded hsqldb,
typically ${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar,
but for now lib/org/hsqldb/hsqldb/r5836/hsqldb-r5836.jar
${SQLTOOL_JAR} contains pathname to where Maven downloaded sqltool,
typically ${HOME}/.m2/repository/org/hsqldb/sqltool/2.4.1/sqltool-2.4.1.jar
${SQLTOOL_RC} contains pathname to a text file describing Qora2 database,
e.g. ${HOME}/.sqltool.rc, with contents like:
urlid qora
url jdbc:hsqldb:file:db/qora
username SA
password
urlid qora-test
url jdbc:hsqldb:file:db/test
username SA
password
You could change the line url jdbc:hsqldb:file:db/test to use a full pathname for easier use.
Another idea is to assign a shell alias in your .bashrc like:
export HSQLDB_JAR=${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar
export SQLTOOL_JAR=${HOME}/.m2/repository/org/hsqldb/sqltool/2.4.1/sqltool-2.4.1.jar
alias sqltool='rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC}'
So you can simply type: sqltool qora-test
Don't forget to use SHUTDOWN; before exiting sqltool so that database files are closed cleanly.
