Added CreatePollTransactionData constructor that doesn't need signature (for creating new transactions). Added missing "published" timestamp support to PollData and Poll. Removed extraneous timestamp test from Block.isValid. Corrected inconsistent column names in poll-related tables in HSQLDBDatabaseUpdates. HSQLDBRepository.checkedExecute(PreparedStatement) now takes extra Object... params so that values can be bound to placeholders. Code moved from checkedExecute(String, Object...). This fixes an issue with exists(String, String, Object...) where placeholders weren't having any values bound to them. (Also removed "ORDER BY NULL" clause which isn't supported by HSQLDB). HSQLDBVotingRepository method stubs fleshed out with real code. TransactionTests rejigged but more work needed to test various transactions before/after their feature release. e.g. testing create poll transactions before & after they supposedly went live. Could do with a GenesisBlock constructor that takes a timestamp for testing purposes? CreatePollTransactionTransformer now skips serializing a null signature, in the same way PaymentTransactionTransformer does, to aid getBytesLessSignature(). This will probably need to be rolled out to all other transaction types. |

Qora2
To use:
- Use maven to fetch dependencies.
- Build project.
- Fire up an old-gen Qora node.
- Run
src/migrate.javaas a Java application 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
Don't forget to use SHUTDOWN; before exiting sqltool so that database files are closed cleanly.
