These are four separate cases where I've actually witnessed myself or

improve the situation a lot.
Of course, an additional or other approach would be to implement a
tool that
checks various things. I agree that the problems you listed are
solvable with
doing the release from the tag, but there are cases that are not
caught:
1. In your last case, if bajium would have used "svn switch --
relocate" the
file would still be around and the release would work. I imagine
that most
people would use "svn switch" because making another checkout is
just a
package management mess.
Why is making another checkout a package management mess? Go to /tmp
or ~/temp or whatever, get the checkout, do your release stuff and
delete it again. Is this so hard? Sorry, but I fail to see how this
is messy.
Also, regardless of what you imagine people do, if the process says
"get a new, fresh checkout" then this is what people should do. If
they use svn switch instead, then they're not following the process.
End of story.
2. My Trove classifier problem is not solved either using this
approach.
Contrary to what Tres hinted on in his E-mail , if there are errors
while
registering with PyPI, no new release is added. Also, "buildout
setup .
egg_info" does not verify the Trove classifiers. (Note that I think
the Trove
classifiers are only one example of something going wrong.)
buildout setup? I've never seen that. I can't find any documentation
on it in zc.buildout. How does it work? Does it call setup.py for
every development egg in buildout.cfg? Why not just call python
setup.py?
Anyway, I think the Trove classifiers are an edge case. I've never
seen anyone get those wrong before, to be honest. I *have* seen
people get other things wrong and I think these problems would all be
solved if we made it impossible to create distributions from a branch
or the trunk, but made people create them from tags instead.
3. A serious problem occurs, if you accidentally specify the wrong
package
name and version in setup.py. Both happened to me yesterday, but I
caught it
in time.
I assume you mean the egg name, not the package name.
I'm not sure how a tool could help you here. I suppose it could use
some conventions (e.g. look at the packages inside the egg) or look
at the subversion URL.
A fairly simple tool can find and report all the problems found and
offer
assistance. I think it is worth investing in one, especially since
it will
reduce my overhead since my manual checking now becomes automated.
I'm not arguing against such a tool. If you are willing to come up
with it, go for it. We should still have a proper *human* process
first. A tool can then help us do the tedious bits.
