[Zope-dev] zope.sqlalchemy dependencies does not respect setup.py dev egg

[David Pratt]

Hi. I have been working with z3c.dobbin 0.4.1 which uses zope.sqlalchemy 
and z3c.saconfig. The last usable state was 4 days ago when changes were 
made to release of zope.sqlalchemy where dependencies were changed 
without changing the version.

Revision 88953 was made to zope.sqlalchemy but shows the same package 
version as 88952 (where SA dependencies were changed to no longer 
include beta0.5.2). beta0.5.2 was the requirement for z3c.dobbin and it 
will not work with beta0.5.3. Malthe is currently making changes to 
dobbin in the interim so it will eventually work again.

I thought by checking out revision 88952 and using it as a dev egg in my 
buildout, I could get back to work. Is this a bug in buildout since dev 
egg should take precedence regardless? I guess there were some problems 
with how this was handled. If trunk had been marked as 0.3dev it might 
have made the difference because both were 0.3 regardless of the change 
of state and dependencies. When I run the buildout the dev egg's 
requires.txt is below regardess of what is in setup.py.  Doesn't matter 
what I do my build fails. Any suggestions? Many thanks.

Regards,
David
