dm-hibernate-adapter aka jibernate

Installation:

  • Install ruby-maven wrapper

    jruby -S gem install ruby-maven

  • setup the gems and compile the java extension

    rmvn clean gem:initialize compile -- -Djruby.version=1.6.4

ruby-maven

  • The ruby-maven setup will generate a pom.xml which can be used by proper maven3.
  • Don't use -o if you want to access remote repositories

Logging

  • use SHOW_SQL=true ENV variable in order to log SQL (except DDL, turned off by default)
  • use FORMAT_SQL=true ENV variable in order to format SQL logs

Howtos:

how to test basic actions with eventlog.rb

  • how to run the eventlog - listing

    rmvn gem exec eventlog.rb list -- -o -Djruby.version=1.6.4

  • how to run the eventlog - storing record

    rmvn gem exec eventlog.rb store something -- -o -Djruby.version=1.6.4

  • how to run the eventlog - storing with rollback

    rmvn gem exec eventlog.rb store_rollback something -- -o -Djruby.version=1.6.4

Rake

  • how to list rake tasks (please note the jruby.rake.args part(var name))

    rmvn rake -T -- -o

Specs

Test suites:

  • AbstractAdapter specs: rmvn rake spec:adapter -- -o or rmvn test -- -Padapter -o
  • dm-core specs: rmvn rake spec:dm -- -o or rmvn test -- -Pdm -o
  • transient specs: rmvn rake spec:transient -- -o or rmvn test -- -Ptransient -o

Tips:

  • when using rmvn test there will be a nice html rspec report in target/rspec-report.html. to get debug output use (use '--' only once which denotes the beginning of maven options) -- -Djruby.verbose -e
  • you can switch the jruby version by adding to the above commands -- -Djruby.version=1.6.3
  • if you are getting OutOfMemory errors, you should try to tune jruby-maven-plugin's settings and set them as properties in 'Mavenfile' - see in that file (ie. properties['jruby.jvmargs'] = '-Xmx1024m')
  • if you are getting problems with specs you can skip that phase: -- -Dmaven.test.skip=true
