Added Apache commons-net as maven dependency for NTP support. Added SAVEPOINT and ROLLBACK TO SAVEPOINT support to DB class. Added exists() test to DB class. Add MessageTransactions, with V1/V3 code in one class instead of very similar code split across two classes. Update DB schema to add version. More fleshing out of Assets class. Fleshing out Block class with parse(), generating balance and signature-related methods. More javadoc. More tests. |

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
