ITK/Release Schedule

The next release is 4.1 scheduled for March 1st, 2012.

Release Life Cycle

Last period for adding classes and features

• New classes will be selected from good reviews from the Insight Journal
• New features and new methods can be added during this period.

Feature Freeze

• Increase code coverage
  • address any UNTESTED files
  • address files with code coverage lower than 80%
• Address Run-time memory issues
  • Purify reports
  • Valgrind reports

RC process

• No new features should merged during the feature freeze, i.e. ENH: commits, although they can be preparred in Gerrit.
• Release candidates (RC's) will be tagged weekly.
• RC's will be tagged after dashboard examination and discussion at the Friday TCon.
• The repository will be hard frozen to only allow merging by gatekeepers on Wednesday evening before the dashboards start. The freeze will be released after tagging.
• For the final RC, only gatekeeper merges will occur.

Posting Tarballs

• Tarballs are posted to SourceForge
• Tarballs are linked from the ITK Download

Check-list for Moving Code from IJ to Gerrit and from Gerrit

For IJ Articles To Gerrit

• Responsible developer should add a review before moving into local copy of Gerrit. Please provide authors with feedback regarding changes that were made to conform to ITK style/documentation etc.

For Adding Images to Input or Baseline

• Images should be SMALL.
  • The source tree is not an image database, but a source code repository.
  • Adding an image larger than 50Kb should be justified by a discussion in the Developers list
• Regression images should not use Analyze format unless the test is for the AnalyzeImageIO and related classes.
• Images should use non-trivial Metadata.
  • Origin should be different form zeros
  • Spacing should be different from ones, and it should be anisotropic
  • Direction should be different from Identity

For Moving Code From Review

• At least one independent (other than contributor) should sign off on the API
• Coverage should be as close to 100% as possible.
  • and never lower than 90%.
  • For example, itkTransformIOBase.cxx is only at 63% coverage. Should be easily fixed by adding a Print() to one of the tests.

For All

• Check all comments for proper English
• Should pass KWStyle. IJ articles should be checked with KWStyle before checking into repository.
• Should pass PrintSelf. IJ articles should pass PrintSelf check before checking into repository.
• ITK_EXPORT should appear in each class definition. This triggers the PrintSelf checker.
• Replace itkGetMacro with itkGetConstMacro.
• Header file should contain Insight Journal citation
  • Using the "handle" link.
• Use vcl verions of all transcendental functions.
  • For example, itkGaborKernelFunction used sin() and cos() rather than vcl_sin() and vcl_cos().
• Progress should be present for all filters. Use itk::SimplerFilterWatcher to exercise progress and PrintSelfs.
• When appropriate, class should handle image directions. Tests should use non-default values for origin, spacing and dimension.
  • GaborImageSource did not provide methods to set/get directions.
• Regression tests names should when possible have the same name as the test.
• Exceptions should be descriptive and provide as much information as possible
• Member data should be private with access if required through Get methods.
