This is mainly causing us problems when projects try to track alpha
and beta level bumps in dependencies, such as when project Foo
requires project Bar version 3.0b1 via a requirement like 'Bar >=
3.0b1' (which means we don't want the development prereleases of
Bar's first beta release, but anything after that should be okay.)
But then when we actually want to release Bar 3.0 and change the
version number to just '3.0', suddenly installs fail while we try to
run the last set of tests because '3.0.dev' is older than '3.0b1'.
If it is not a bug, how do you handle situations where you want to
run that last round of testing prior to tagging and building
releases? I'd rather do that AFTER making all source changes, and
not have to change the version number after the testing.
This is what 'rc' tags are for, actually. You can put your version in
the source, and use the -b option to egg_info while doing builds and
testing to tack on an 'rc' tag, possibly with a subversion number as
well.
Perhaps I'm missing something, but that doesn't seem like it scales to a
community -- not everyone is going to remember to use a '-b' option when
building and that is going to cause endless support problems. We do
put the following in our setup.cfg so that people don't mistakenly build
release versions when not intending to do so:
[egg_info]
tag_build = .dev
tag_svn_revision = 1
Are you staying the standard process for setuptools is to delete /
modify this when tagging a release in the repo? If not, how do you
avoid the problem of someone building from a source checkout and finding
out that 3.0.dev-r1234 doesn't satisfy the '>= 3.0b1' dependency spec?
