catbref 09ffd6fe6b Blockchain replacement for launch. These changes are for allowing devices to be shipped with an interim blockchain config & genesis block, running with "main-net" settings, prior to launch. At launch, an "auto-update" will be broadcast to replace blockchain config & genesis block with the final, launch version. When updated nodes restart (immediately after auto-update) they should notice their existing genesis blocks are invalid and hence wipe their blockchains, effectively starting the final, launch blockchain. To this end, genesis block signatures have been changed to better incorporate values that are likely to change at launch, e.g. block timestamp and transaction data. Added Crypto.dupDigest(), which is effectively Bytes.concat(digest(msg), digest(msg)). No need for HSQLDB repository to backup, or wipe, non-existent files for "in-memory" databases! New interim blockchain config/genesis block. NOTE These changes are being committed but require testing. However the auto-update suite requires a pushed commit in order to build an update file!		2019-12-17 16:19:35 +00:00

((Qora2)) - Qortal Project - Official Repo

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.jar to 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.
