Uploading to pypi (or custom servers)¶
When the (full)release command tries to upload your package to a pypi server,
zest.releaser basically just executes the command
python setup.py register
sdist --formats=zip upload.
For safety reasons zest.releaser will only offer to upload your package to https://pypi.python.org when the package is already registered there. If this is not the case yet, you get a confirmation question whether you want to create a new package.
setup.py register ... command fails, you probably need to configure
your PyPI configuration file. And of course you need to have
PyPI configuration file (
For uploads to PyPI to work you will need a
.pypirc file in your home directory that
has your pypi login credentials, like this:
[server-login] username:maurits password:secret
Uploading to other servers¶
Since python 2.6 you can specify multiple indexes for uploading your
package in your
[distutils] index-servers = pypi local [pypi] #pypi.python.org username:maurits password:secret [local] repository:http://localhost:8080/test/products/ username:maurits password:secret # You may need to specify the realm, which is the domain the # server sends back when you do a challenge: #realm:Zope
See the Python Packaging User Guide for more info.
When all this is configured correctly, zest.releaser will first register and
upload at the official PyPI (if the package is registered there already).
Then it will offer to upload to the other index servers that you have
Note that since version 3.15, zest.releaser also looks for this information in the setup.cfg if your package has that file. One way to use this, is to restrict the servers that zest.releaser will ask you upload to. If you have defined 40 index-servers in your pypirc but you have the following in your setup.cfg, you will not be asked to upload to any server:
[distutils] index-servers =
Note that after creating the tag we still ask you if you want to checkout that tag for tweaks or pypi/distutils server upload. We could add some extra checks to see if that is really needed, but someone who does not have index-servers listed, may still want to use an entry point like gocept.zestreleaser.customupload to do uploading, or do some manual steps first before uploading.
Some people will hardly ever want to do a release on PyPI but in 99 out of 100
cases only want to create a tag. They won’t like the default answer of ‘yes’
to that question of whether to create a checkout of the tag. So since version
3.16 you can influence this default answer. You can add some lines to the
.pypirc file in your home directory to change the default answer for all
packages, or change it for individual packages in their
The lines are this:
[zest.releaser] release = no
You can use no/false/off/0 or yes/true/on/1 as answers; upper, lower or mixed case are all fine.
Uploading with twine¶
Since version 6.0, we always use twine for uploading to the Python
Package Index, because it is safer: it uses
https for uploading.
Since version 4.0 we already prefered it if it was available, but it
is now a core dependency, installed automatically.
First, you should install the
zest.releaser[recommended] extra, or
pip install wheel yourself next to
create or edit
setup.cfg in your project (or globally in your
~/.pypirc) and add this to create and upload a wheel to upload to
[zest.releaser] create-wheel = yes
See http://pythonwheels.com for deciding whether this is a good idea for your package. Briefly, if it is a pure Python 2 or pure Python 3 package: just do it.
Adding extra text to a commit message¶
zest.releaser makes commits in the prerelease and postrelease
phase. Something like
Preparing release 1.0 and
development: 1.1. You can add extra text to these messages by
configuration in your
setup.cfg or global
~/.pypirc. One use
case for this is telling Travis to skip Continuous Integration builds:
[zest.releaser] extra-message = [ci skip]
Including all files in your release¶
By default, only the Python files and a
README.txt are included (by
setuptools) when you make a release. So you miss out on your changelog, json
files, stylesheets and so on. There are two strategies to include those other
- Add a
MANIFEST.infile in the same directory as your
setup.pythat lists the files you want to include. Don’t worry, wildcards are allowed. Actually, zest.releaser will suggest a sample
MANIFEST.infor you if you don’t already have it. The default is often good enough.
- Setuptools can detect which files are included in your version control system (svn, git, etc.) which it’ll then automatically include.
The last approch has a problem: not every version control system is supported
out of the box. So you might need to install extra packages to get it to
work. So: use a
MANIFEST.in file to spare you the trouble. If not, here
are some extra packages:
- setuptools-git (Setuptools plugin for finding files under Git version control)
- setuptools_hg (Setuptools plugin for finding files under Mercurial version control)
- setuptools_bzr (Setuptools plugin for finding files under Bazaar version control)
- setuptools_subversion (Setuptools plugin for finding files under Subversion version control.) You probably need this when you upgrade to the recent subversion 1.7. If you suddenly start missing files in the sdists you upload to PyPI you definitely need it. Alternatively: set up a proper MANIFEST.in as that method works with any version control system.
In general, if you are missing files in the uploaded package, the best
is to put a proper
MANIFEST.in file next to your
See zest.pocompile for an example.
Running automatically without input¶
Sometimes you want to run zest.releaser without hitting
<enter> all the
time. You might want to run zest.releaser from your automatic test
environment, for instance. For that, there’s the
option. Pass that and all defaults will be accepted automatically.
This means your version number and so must be OK. If you want to have a
different version number from the one in your
setup.py, you’ll need to
change it yourself by hand. And the next version number will be chosen
automatically, too. So
1.2 will become
1.3. This won’t detect that you
might want to do a
1.3 after a
1.2.1 bugfix release, but we cannot
perform feats of magic in zest.releaser :-)
In case you always want to accept the defaults, a setting in your
setup.cfg is available:
[zest.releaser] no-input = yes
An important reminder: if you want to make sure you never upload anything
automatically to the python package index, include the
release = no
[zest.releaser] no-input = yes release = no
