A guide for developers who are doing a dipy release
There are some release utilities that come with nibabel. nibabel should install these as the nisext package, and the testing stuff is understandably in the testers module of that package. Dipy has Makefile targets for their use. The relevant targets are:
make check-version-info
make sdist-tests
The first installs the code from a git archive, from the repository, and for in-place use, and runs the get_info() function to confirm that installation is working and information parameters are set correctly.
The second (sdist-tests) makes an sdist source distribution archive, installs it to a temporary directory, and runs the tests of that install.
If you have a version of nibabel trunk past February 11th 2011, there will also be a functional make target:
make bdist-egg-tests
This builds an egg (which is a zip file), hatches it (unzips the egg) and runs the tests from the resulting directory.
Review the open list of issues . Check whether there are outstanding issues that can be closed, and whether there are any issues that should delay the release. Label them !
Review and update the release notes. Review and update the Changelog file. Get a partial list of contributors with something like:
git log 0.4.0.. | grep '^Author' | cut -d' ' -f 2- | sort | uniq
where 0.4.0 was the last release tag name.
Then manually go over the git log to make sure the release notes are as complete as possible and that every contributor was recognized.
Check the long_description in dipy/info.py. Check it matches the README in the root directory.
Clean and compile:
make distclean
python setup.py build_ext --inplace
Make sure all tests pass (from the dipy root directory):
cd ..
nosetests --with-doctest dipy
cd dipy # back to the root directory
Check the documentation doctests:
cd doc
make doctest
cd ..
At the moment this generates lots of errors from the autodoc documentation running the doctests in the code, where the doctests pass when run in nose - we should find out why this is at some point, but leave it for now.
Make sure all tests pass from sdist:
make sdist-tests
and bdist_egg:
make bdist-egg-tests
and the three ways of installing (from tarball, repo, local in repo):
make check-version-info
The last may not raise any errors, but you should detect in the output lines of this form:
{'sys_version': '2.6.6 (r266:84374, Aug 31 2010, 11:00:51) \n[GCC 4.0.1 (Apple Inc. build 5493)]', 'commit_source': 'archive substitution', 'np_version': '1.5.0', 'commit_hash': '25b4125', 'pkg_path': '/var/folders/jg/jgfZ12ZXHwGSFKD85xLpLk+++TI/-Tmp-/tmpGPiD3E/pylib/dipy', 'sys_executable': '/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python', 'sys_platform': 'darwin'}

The release should now be ready.
Edit dipy/info.py to set _version_extra to ''; commit
Build the release files:
make distclean
make source-release
Once everything looks good, upload the source release to PyPi. See setuptools intro:
python setup.py register
python setup.py sdist --formats=gztar,zip upload
Then upload the binary release for the platform you are currently on:
python setup.py bdist_egg upload
Do binary builds for any virtualenvs you have:
workon python25
python setup.py bdist_egg upload
deactivate
etc. (workon is a virtualenvwrapper command).
Repeat binary builds for Linux 32, 64 bit and OS X.
Get to a windows machine and do egg and wininst builds:
make distclean
c:\Python26\python.exe setup.py bdist_egg upload
c:\Python26\python.exe setup.py bdist_wininst --target-version=2.6 register upload
Maybe virtualenvs for the different versions of python? I haven’t explored that yet.
Tag the release with tag of form 0.5.0:
git tag -am 'First public release' 0.5.0
Now the version number is OK, push the docs to sourceforge with:
make upload-htmldoc-mysfusername
where mysfusername is obviously your own sourceforge username.
Set up maintenance / development branches
If this is this is a full release you need to set up two branches, one for further substantial development (often called ‘trunk’) and another for maintenance releases.
Branch to maintainance:
git co -b maint/1.0.x
Set _version_extra back to .dev and bump _version_micro by 1. Thus the maintenance series will have version numbers like - say - ‘0.5.1.dev’ until the next maintenance release - say ‘0.5.1’. Commit.
Start next development series:
git co main-master
then restore .dev to _version_extra, and bump _version_minor by 1. Thus the development series (‘trunk’) will have a version number here of ‘0.6.0.dev’ and the next full release will be ‘0.6.0’.
If this is just a maintenance release from maint/0.5.x or similar, just tag and set the version number to - say - 0.5.2.dev.
Make a tarball for the examples, for packagers to get away without having vtk or a display on the build machines:
cd doc
make examples-tgz
The command requires pytables and python vtk on your machine. It writes an archive named for the dipy version and the docs, e.g:
<dipy root>/dist/dipy-0.5.0.dev-doc-examples.tar.gz
We need to decide where to put this tarball.
