I propose that buildout-versions get incorporated into buildout in the following way:
OK, proposal 1 wasn't accepted. Here's another stab:
Proposal 2 ----------
1. The ``allow-picked-versions`` option gets a new allowed value of ``show``. if there are unpicked versions and this option is set to ``show``, then picked/unpinned versions are reported in a way suitable for copying into a versions section, presumably with the same format used by buildout-versions today.
2. New buildout option: ``update-versions-file``. This takes a path (relative to buildout directory) of a file to update with any unpinned versions (in a manner roughly the same as buildout-versions does today).
3. New buildout option: ``python-version`` that restricts the Python version, with the same semantics as buildout-version provides now.
4. Change: develop eggs found in the buildout's develop-eggs directory will be used even if their version conflicts with a pinned version.
I'm not sure about this one. Is the develop-eggs directory always cleaned up during a buildout run so only the eggs in the 'develop' option are listed there? If old eggs are kept there, this may lead to unexpected results, where old developed eggs are still used even when the buildout config does not mention them. If an egg is explicitly in the 'develop' option, then I would be +1 on favouring that over a pinned version. This indeed trips me up sometimes in current buildout 1, so this could help.
5. In buildout 2, The default value of the versions option will be "versions", rather than being unset. This will allow users to omit::
version = versions
from their buildout section.
6. To make it a little easier to supply buildout versions on the command line, make buildout the default section for command-line options, so::
update-versions-file=versions.cfg
or::
allow-picked-versions=show
would be allowed. (They are rejected now.)
Thoughts?
