Versioning

Project fork

While Slicer specific patches related to dependent project (i.e. VTK) are integrated upstream, it is not uncommon to build Slicer against a Slicer specific fork of the project.

For example: https://github.com/Slicer/VTK

Patches for tagged release

For each version of the project requiring some specific patches, a branch following that convention will be created: slicer-vX.Y.Z where X.Y.Z corresponds to the version of the project.

For example, in case of the SlicerVTK fork, the branch slicer-v5.10.1 has been created.

Patches for development branch

In this case, since there is no tag associated with the branch, the Slicer specific patch should be added to a branch named using the date of the commit parent of the Slicer branch: slicer-YEAR-MONTH-DAY-vX.Y where X.Y corresponds to the fork release.

Create release dashboard scripts

Feature freeze

Usually ~1 month before release.

Prerequisites

• Update modules documentation link in help section (loadable, scripted and cli)
  • And some html links in Welcome module (Modules/Loadable/SlicerWelcome/Resources/HTML)
  • Update CLI XML description files

Commit message: Update Documentation to X.Y

For example: r22407

Release-candidate

Since there all development occurs on master, each time version is updated, two commits will be required.

<RC> corresponds to the release candidate number. It is greater or equal to one.

1. In CMakeLists.txt, uncomment and set:

   • Slicer_VERSION_TWEAK to 0
   • Slicer_VERSION_RC to 1, 2 or 3

   ... and if this is the first release candidate, update at least one these variables: Slicer_VERSION_MAJOR, Slicer_VERSION_MINOR, Slicer_VERSION_PATCH

2. Commit CMakeLists.txt changes using this message:

   ENH: Slicer X.Y.Z-rc<RC>

3. Generate packages based on REVISION associated with step1.

4. In CMakeLists.txt, comment Slicer_VERSION_TWEAK so that the next builds will contain the date associated with the last commit.

5. Commit CMakeLists.txt changes using this message:

   ENH: Begin post-X.Y.Z-rc<RC> development

Release

Since there all development occurs on master, each time version is updated, two commits will be required.

1. In CMakeLists.txt, uncomment and set Slicer_VERSION_TWEAK to 0

   ... and if this no release candidate has been made, update at least one these variables: Slicer_VERSION_MAJOR, Slicer_VERSION_MINOR, Slicer_VERSION_PATCH

2. Commit CMakeLists.txt changes using this message:

   ENH: Slicer X.Y.Z

3. Generate packages based on REVISION associated with step1.

   Tag the repository:

     svn copy -r<REVISION> http://svn.slicer.org/Slicer4/trunk  \
          http://svn.slicer.org/Slicer4/tags/Slicer-X-Y  \
         -m "ENH: Tag of X.Y.Z release based on r<REVISION>."
    

4. In CMakeLists.txt, comment and set:

   • Slicer_VERSION_TWEAK to 0 so that the next builds will contain the date associated with the last commit.
   • Slicer_VERSION_RC to 0

5. Commit CMakeLists.txt changes using this message:

   ENH: Begin post-X.Y.Z development

Post release

Create a release branch

svn copy -r <REVISION> http://svn.slicer.org/Slicer4/trunk http://svn.slicer.org/Slicer4/branches/Slicer-X-Y \
 -m "ENH: Branching from trunk to Slicer-X-Y at <REVISION>"

Generate ChangeLog

• See gitlog2changelog.py. More details here.

• Update Release Details page using generated ChangeLog

Update Mantis

• "Release" current target
• Create new target
• Check the "fixed in" fields

Midas

Tag release packages

• If needed, create a X.Y.Z folder in Slicer/Packages/Application/Release
  • Copy uploaded packages into the folder created above
  • Identify the item_id associated with uploaded packages. For example: 11926, 11925, 11927, 11992
  • SSH connect to jcfr@slicer.kitwarein.com
  • Connect to mysql using mysql -u midas -p
    • See file /var/www/midas3/core/configs/database.local.ini for password
    • Choose midas database: use midas
  • List packages associated with identified items and check they are the appropriate ones:
    • select * from slicerpackages_package as p , item as i where i.item_id = p.item_id and p.item_id in (11926, 11925, 11927, 11992);
  • Set release field
    • update slicerpackages_package set `release`="4.2.2-1" where item_id in (11926, 11925, 11927, 11992);

Version NA-MIC data tree

1. Create an account on the extension server and obtain an API Key. You will then use your midas login and api key to substitute <YOUR-MIDAS-LOGIN> and <YOUR-MIDAS-APIKEY> in the examples.

2. If not already done, go to NA-MIC community and click on Join community

3. Send an email on the developer list asking to be added to the DataManager group on NA-MIC community. That will grant you read/write permissions to the Data folder and sub-folders.

4. Install prerequisites

   $ sudo pip install pydas
   

5. Identify id of the Data folder. For example 301

6. Simulate creation of X.Y data folders based Nightly ones

   $ cd /path/to/Slicer/Base/Python/slicer/release
   $ python midasdata.py --url=http://slicer.kitware.com/midas3 --data_id=301 \
     --email=<YOUR-MIDAS-LOGIN> --apikey=<YOUR-MIDAS-APIKEY> --source_version=Nightly --dest_version=X.Y --dry-run
   Application ( folder_id: 302 )
   '-Nightly ( folder_id: 831 )
   '-'-Testing ( folder_id: 832 )
   '-'-'-Baseline ( folder_id: 889 )
   '-'-'-'-DiffusionTensorImagingTutorial.png ( item_id: 12067 )
   '-'-'-'-NeurosurgicalPlanningTutorial.png ( item_id: 12066 )
   '-'-'-'-SlicerTestingTest.png ( item_id: 17760 )
   '-'-'-Input ( folder_id: 833 )
   '-'-'-'-AtlasTests ( folder_id: 834 )
   '-'-'-'-'-2012-10-26-BrainAtlas.mrb ( item_id: 10276 )
   [...]
   Module: VotingBinaryHoleFillingImageFilter ( folder_id: 1491 )
   '-Nightly ( folder_id: 1491 )
   '-'-Testing ( folder_id: 1492 )
   '-'-'-Baseline ( folder_id: 1493 )
   '-'-'-'-VotingBinaryHoleFillingImageFilterTest.nhdr ( item_id: 103418 )
   '-'-'-'-VotingBinaryHoleFillingImageFilterTest.raw.gz ( item_id: 103419 )
   
   

7. Create X.Y data tree based Nightly ones

   $ python midasdata.py --url=http://slicer.kitware.com/midas3 --data_id=301 \

Update Slicer wiki

The copy of the pages associated with the Nightly namespace into the X.Y namespace is done using the convenience python module mwdoc.

1. Check with <email>jchris.fillionr@kitware.com</email> to get the credential associated with UpdateBot user.

2. Copy Nightly pages into X.Y pages.

   $ cd ~/Projects
   
   $ sudo pip install mwclient
   
   $ git clone git://github.com/jcfr/mwdoc
   
   $ cd mwdoc
   
   $ python
   
   >>> import mwdoc
   >>> doc = mwdoc.Documentation('slicer.org', '/slicerWiki/')
   >>> doc.login('UpdateBot', 'XXXXXXX')
   >>> doc.versionPages('Nightly', '4.3', ['Documentation', 'Template:Documentation'])
   [INFO] Page successfully created: 'Documentation/4.3/Extensions/ErodeDilateLabel'

3. Update Template:Documentation/nextversion

4. Update Template:Documentation/currentversion

5. Update Template:Documentation/versionlist

6. Update FAQ

7. Update Documentation

CDash

1. Create new CDash groups for extension submissions associated with X.Y release:

   Extensions-X.Y-Nightly
   Extensions-X.Y-Continuous
   

Update external website

See http://en.wikipedia.org/wiki/3DSlicer

Backport commit into release branch

The following steps will lead to the creation of new git-svn clone having two branches:

• git-svn
• git-svn-XY

Reference: http://www.dmo.ca/blog/20070608113513/

Step 1: Checkout sources

git clone git://github.com/Slicer/Slicer.git Slicer-X.Y
cd Slicer-X.Y
git svn init http://svn.slicer.org/Slicer4/trunk
git update-ref refs/remotes/git-svn refs/remotes/origin/master
git checkout master
git svn rebase

Step 2: Add release branch remote

Edit .git/config, and in addition to the existing 'git-svn' remote, add the following one:

[svn-remote "svn-XY"]
   url = http://svn.slicer.org/Slicer4/branches/Slicer-X-Y
   fetch = :refs/remotes/git-svn-XY

Step 3: Pull associated SVN branch

git svn fetch git-svn-XY -r <REVISION>
git checkout -b master-XY git-svn-XY

Step 4: Backport

We can now cherry pick commit associated with master (trunk) into master-XY (Slicer-X-Y)

Step 5: Create a patch release

Slicer Package naming scheme

Slicer-<MAJOR_VERSION>.<MINOR_VERSION>.<PATCH_VERSION>[-rc{1|2|3...}][-<TWEAK_VERSION>][-<DATE>][-svn<REV>][-dirty]-<ARCH>-<PLATFORM>

There are 2 types of builds, releases and developments:

Release

Special builds made on a given revision (e.g. r19033: "ENH: Slicer 4.0.1")

Don't contain date or revision number.

The optional suffix -rc{1|2|3|...} identifies the release candidates leading to a final release.

Eventually, a tweak number can be added (e.g. 4.0.1-1)

Development

Nightly or experimental builds

Contains suffixes after the major.minor.patch version

The suffix svn<REV> allows to identify the revision associated with the current package.

The -dirty prefix indicates if the package has been generated from a locally modified source tree.
