I'm *not* kidding about that: taking shortcuts durng the release
process transfers pain / cost to everyone downstream.
While I fully agree that releases should be done with care and
attention, and that doing bad releases creates pain/cost for
everybody, this line of argumentation can be used to back up any form
of complication to the release process. :)
Let's focus on the reasons for each step and keep the discussion at
that level, please? I think it's useful if people ask "is that really
necessary?" for steps in the release process. Just weigh the pros and
cons. I'd like to understand more about the trouble Philipp ran into
doing releases from the original checkout and then tagging.
I've summarized this in another thread , but I'll be happy to
* People actually forget to make the tag. This happened to Roger the
other day. It happened to Jim before with zc.buildout. I'm not
mentioning their names to point fingers. I'm just pointing out that
people who've been with us for a long time forget. If the process
said they should actually check out the tag, they'll hardly forget.
* People create the wrong tags or tags in the wrong places. This
happened to Jim the other day with ZODB 3.7.1. Again, I'm not blaming
him. But I believe if he had to check out the tag to make the
release, he would've caught his mistake.
* People forget to clean up the 'build' directory. This happened to
me the other day. Let me elaborate: I have a trunk checkout of
zopeproject that I use to develop it. Whenever I wanted to make a
release, I'd just prepare it, tag it and generate the distributino
from the trunk checkout. The problem was that I had moved stuff
around, but the old stuff was still making it to the egg because it
still sat around in the 'build' direcdtory that distutils leaves. I
know it sucks that distutils doesn't clean up after itself, but
that's just the way it is. If you're forced to use a clean checkout,
this can't happen.
* People forget to check in important files. This happened to Baiju
the other day. He created a CHANGES.txt file and referred to it from
setup.py. The only problem is that he forgot to check it in. It can
happen, I'm not blaming him. The problem is that setuptools looks at
which files are in svn in order to create the archive manifest. So
CHANGES.txt wasn't in the tarball and the egg was completely
uninstallable (because setup.py couldn't be executed since
CHANGES.txt was missing).
These are four separate cases where I've actually witnessed myself or
other people mess up. We're forgetful, we can't do anything about
that. We can, however, force us to catch our mistakes. I believe that
if we made everybody create the tarballs from the tag, it would
improve the situation a lot.
I'm beginning to see a consensus that we should make it impossible to
create distributions from the trunk or a release branch.
