Class utilMain

java.lang.Object
org.apache.derby.impl.tools.ij.utilMain
public class utilMain extends Object
This class is utilities specific to the two ij Main's. This factoring enables sharing the functionality for single and dual connection ij runs.

  • Constructor Details

    • utilMain

      utilMain(int numConnections, LocalizedOutput out) throws ijFatalException
      Set up the test to run with 'numConnections' connections/users.
      Parameters:
      numConnections - The number of connections/users to test.
      Throws:
      ijFatalException

    • utilMain

      utilMain(int numConnections, LocalizedOutput out, boolean loadSystemProperties) throws ijFatalException
      Set up the test to run with 'numConnections' connections/users. This overload allows the choice of whether the system properties will be used or not.
      Parameters:
      numConnections - The number of connections/users to test.
      Throws:
      ijFatalException

    • utilMain

      public utilMain(int numConnections, LocalizedOutput out, Hashtable ignoreErrors) throws ijFatalException
      Set up the test to run with 'numConnections' connections/users.
      Parameters:
      numConnections - The number of connections/users to test.
      ignoreErrors - A list of errors to ignore. If null, all errors are printed out and nothing is fatal. If non-null, if an error is hit and it is in this list, it is silently ignore. Otherwise, an ijFatalException is thrown. ignoreErrors is used for stress tests.
      Throws:
      ijFatalException

  • Method Details

    • initFromEnvironment

      public void initFromEnvironment()
      Initialize the connections from the environment.

    • go

      public void go(LocalizedInput[] in, LocalizedOutput out) throws ijFatalException
      run ij over the specified input, sending output to the specified output. Any prior input and output will be lost.
      Parameters:
      in - source for input to ij
      out - sink for output from ij
      Throws:
      ijFatalException

    • goScript

      public int goScript(Connection conn, LocalizedInput in)
      Support to run a script. Performs minimal setup to set the passed in connection into the existing ij setup, ConnectionEnv.
      Parameters:
      conn -
      in -

    • supportIJProperties

      private void supportIJProperties(ConnectionEnv env)

    • runScriptGuts

      private int runScriptGuts()
      Run the guts of the script. Split out to allow calling from the full ij and the minimal goScript.
      Returns:
      The number of errors seen in the script.

    • cleanupGo

      private void cleanupGo(LocalizedInput[] in)
      Perform cleanup after a script has been run. Close the input streams if required and shutdown derby on an exit.
      Parameters:
      in -

    • displayResult

      private void displayResult(LocalizedOutput out, ijResult result, Connection conn) throws SQLException
      Throws:
      SQLException

    • doCatch

      private boolean doCatch(String command)
      catch processing on failed commands. This really ought to be in ij somehow, but it was easier to catch in Main.

    • handleSQLException

      private void handleSQLException(LocalizedOutput out, SQLException e) throws ijFatalException
      This routine displays SQL exceptions and decides whether they are fatal or not, based on the ignoreErrors field. If they are fatal, an ijFatalException is thrown. Lifted from ij/util.java:ShowSQLException
      Throws:
      ijFatalException

    • doTrace

      private void doTrace(Throwable t)
      stack trace dumper

    • newInput

      void newInput(String fileName)

    • newResourceInput

      void newResourceInput(String resourceName)

    • doPrompt

      static void doPrompt(boolean newStatement, LocalizedOutput out, String tag)
      REMIND: eventually this might be part of StatementFinder, used at each carriage return to show that it is still "live" when it is reading multi-line input.

    • setMtUse

      void setMtUse(boolean b)
