catbref 5b78268915 Convertion to thread-local Connection
Much tidier code thanks to not having to pass Connection objects around
as params. Also no need for two forms of the same method, one with Connection
param, one without.

Also corrected SQL-Transaction-related methods in DB, e.g. commit, rollback, etc.
so they use the proper underlying JDBC methods.

Qora2

To use:

  • Use maven to fetch dependencies.
  • Build project.
  • Fire up an old-gen Qora node.
  • Run src/test/update.java as a JUnit test to build DB structure.
  • Run src/test/migrate.java as a JUnit test to migrate old Qora blocks to DB.

You should now be able to run src/test/load.java and src/test/save.java as JUnit tests demonstrating loading/saving Transactions from/to database.

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 hsqldb-2.4.0.jar, typically ${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar

${SQLTOOL_JAR} contains pathname to where you downloaded sqltool-2.2.6.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/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:

alias sqltool='rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC}'

So you can simply type: sqltool qora
