Authorship
Since contribution have been integrated using the svn dcommit --add-from-author
, the history should be filtered to change the commit author as specified in the From:

Commit message
The following commit message could be fixed:
STYLE: Add test for CLI Node status update This commit adds a test checking that CLI status has the expected value following StatusModifiedEvent. Possible status are the following: Idle Scheduled Running Cancelling Cancelled Completing Completed ErrorsMask CompletedWithErrors BusyMask Note that the status is inconsistently update between synchronous and asynchronous mode. This will be addressed in a follow up commit.
Removing binary data from history
Motivation:
- Speedup time required to checkout Slicer source code.
- Quote "Because of the decentralized nature of Git, which means every developer has the full change history on his or her computer, changes in large binary files cause Git repositories to grow by the size of the file in question every time the file is changed and the change is committed. The growth directly affects the amount of data end users need to retrieve when they need to clone the repository." See https://www.perforce.com/blog/storing-large-binary-files-in-git-repositories
Tasks:
- Filter the history
- Remove file above <= X MB that have a poor compression ratio. See git_list_largest_file_from_history.sh and slicer_git_history_350_largest_files.txt
- Integrate a NOTE with location of files and checksum
Some stats:
- Hina, Jc (from Kitware Carrboro): 3min30sec
- Andrey (SPL): 2m13s
- Steve (Cambridge): 21s (full history), 8s (with --depth=1)
Todo:
- Distribution of binary files across revision.
- Leverage CMake ExternalData module. Existing modules need to be updated to leverage it. Work-in-progress in 02_Update_Slicer_CLI_buildsystem_to_download_test_data_from_midas.ipynb notebook to update buildsystem.
- Improve the SampleData module. See https://discourse.slicer.org/t/improving-testing-data-management-for-self-test/
- Copy testing data to https://github.com/Slicer/SlicerTestingData and work with Kitware system admin to set redirect for existing datasets.
- experiment with history filter and compare with above stats
