I have now also distributed myproject version 1.1. (This has a
base.jinja2 file and requires Jinja2[i18n], which I need for checking
a corner case; I may report that later).
Installing 1.1 unexpectedly gives problems, both with pip and
zc.buildout.
- zc.buildout 2.2.5 and setuptools 7.0: all is well.
- zc.buildout 2.3.1 and setuptools 8.0.4:
* When I specify 'myproject = 1.1' in the buildout config, myproject
does not get updated. It sticks at version 1.1+maurits.3.
* In fact, when I switch back to 1.0, run bin/buildout, again switch
to 1.1, run bin/buildout, the result is that 1.1+maurits.3 is used.
- pip 1.5.6, setuptools 7.0:
* pip warns about three different versions:
$ pip install -U -f
http://pypi.zestsoftware.nl/public/packagingtest/ myproject==1.1
Downloading/unpacking myproject==1.1
Downloading myproject-1.1+maurits.3.zip
Running setup.py
(path:/Users/mauritsvanrees/tmp/venv-older/build/myproject/setup.py)
egg_info for package myproject
Requested myproject==1.1, but installing version 1.1-maurits.3
* The warning is correct: not 1.1, but 1.1-maurits.3 is installed.
- pip dev, setuptools 8.0.4:
* With currently 1.1+maurits.3 installed, pip says:
$ pip install -U --trusted-host pypi.zestsoftware.nl -f
http://pypi.zestsoftware.nl/public/packagingtest/ myproject==1.1
Requirement already up-to-date: myproject==1.1 in
./lib/python2.7/site-packages
* With 1.0 currently installed, pip says:
$ pip install -U --trusted-host pypi.zestsoftware.nl -f
http://pypi.zestsoftware.nl/public/packagingtest/ myproject==1.1
Collecting myproject==1.1
Downloading myproject-1.1+maurits.3.zip
* Result is indeed that myproject 1.1+maurits.3 is installed
instead of 1.1.
Given that both zc.buildout and pip have a problem, I am guessing that
there is a bug in setuptools. I'll report it.
