No need for DB.executeUsingBytes as it was only a specific use-case for DB.checkedExecute. Callers now refactored to use DB.checkedExecute instead. Minor tidying up of BlockTransactions in light of above. In the HSQLDB database, asset keys/IDs are now "asset_id" (previously: "asset"). Added initial Asset/Order/Trade classes. Added CreateOrderTransaction class. Renamed some asset-related fields back to old gen1 names, e.g. haveAmount -> amount, wantAmount -> price. Added Accounts and AccountBalances to database. Added get/set confirmed balance support to Account. Added get/set last reference support to Account. Added Block.toJSON() - untested at this time. Fleshed out some Transaction sub-classes' process() and orphan() methods. Fleshed out PaymentTransaction.isValid(). Added Transaction.delete() - untested. |

Qora2
To use:
- Use maven to fetch dependencies.
- Build project.
- Fire up an old-gen Qora node.
- Run
src/test/update.javaas a JUnit test to build DB structure. - Run
src/test/migrate.javaas 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
