| ==Introduction==
| | #REDIRECT [[ITK/Git/Develop]] |
| | |
| This document is intended to give the bare minimum to get up and running with ITK, and to develop and commit code to the main ITK repository. There is a [[Media:GitITKCheatSheet.pdf|one page PDF cheat sheet]] intended to be a desk reference. Please refer to the general [[ITK/Git| Git guide]] for more details on Git configuration, the branchy workflow employed and the topic stage used for integration of topic branches.
| |
| | |
| All work should be developed in a topic branch, which is branched from the master branch. The topic branch should be staged and merged into master when ready. This facilitates a workflow where big changes can be made, tested and integrated into the mainline development tree (master) when ready for inclusion.
| |
| | |
| ==Initial Setup==
| |
| | |
| Assuming you have your SSH key set up correctly. Run the following to clone ITK:
| |
| | |
| $ git clone --recursive git://itk.org/ITK.git ITK
| |
| $ cd ITK
| |
| $ ./Utilities/SetupForDevelopment.sh
| |
| | |
| The last step installs local hooks, adds a topic stage, Gerrit and sets up some useful Git aliases that will be used later.
| |
| | |
| ==Updating ITK==
| |
| | |
| To update ITK (pullall updates submodules and ITK):
| |
| | |
| $ git checkout master
| |
| $ git pullall
| |
| | |
| ==Starting a Topic Branch==
| |
| | |
| To start a new topic branch:
| |
| | |
| $ git fetch
| |
| $ git checkout -b my-topic origin/master
| |
| | |
| Develop on this topic branch, make commits using, (omit the -m to use an editor)
| |
| | |
| $ git add file1 file2 file3
| |
| $ git commit -v
| |
| | |
| ==Pushing Your Changes for Review==
| |
| | |
| You can check what commits will be pushed to Gerrit for review,
| |
| | |
| $ git prepush
| |
| | |
| To push those commits in your topic branch for review by the community,
| |
| | |
| $ git gerrit-push
| |
| | |
| ==Staging and Publishing a Topic to Next and Master==
| |
| | |
| Once your topic branch has been successfully reviewed, from your topic branch, to merge your change(s) into master:
| |
| | |
| $ git stage-push
| |
| $ git stage-merge
| |
| | |
| ==Deleting Topic Branches==
| |
| | |
| Once you are done, you should delete your topic branch (as it is merged into master and complete).
| |
| | |
| $ git checkout master
| |
| $ git pull
| |
| $ git branch -d my-topic
| |
| | |
| The last line will only succeed if you have correctly merged your branch to master. Using -D instead of -d will force the deletion of an unmerged topic branch (warning - you could lose commits).
