Indeed, but the other option requires a more complicated service to query.
Being able to "serve" packages from a simple folder or from simple folder
served via svn or Apache is a huge win.
I don't see how one preclude the other.
How would you serve your proposed "rich" environment from Apache?
The combination alone makes it complicated very fast. Trying
to come up with such a scheme in python is foolish IMHO: the problem
is complicated, and nobody has been able to solve it in a general
manner anyway.
I think that's overly pessemistic. What problems do you see with the
multiple-find-links suggestion I made above?
It quickly becomes intractable once you have complex requirements.
Again, I think you're being overly pessimistic. Please can you give an
actual example?
I don't see how egg changes anything there compared to rpm/deb to that
issue. At least, rpm/deb and the infrastructure around have been
designed to somewhat deal with those issues, whereas egg clearly was
not.
rpm/deb focus only on their own operating system. They don't help with
Windows or MacOS. Eggs work the same on all platforms, from the clients
perspective, it's just a case of making the right eggs available that
appears to be problematic.
EPD can use eggs because they pretty much control the whole stack from
python, hence significantly reducing the issues of dependencies
issues.
I don't follow. EPD uses a whole host of dependencies that are non-python...
Working with sdists as much as possible with binary eggs thrown in where
possible seems like the best way forward for me. What are the problems you
see with that solution?
The numerous issues of dealing with ABI issues on Linux are well
known. First there is UCS2 vs UCS4 for python extensions, then there
is gcc versions and stdlib versions for C++, then you will also have
issues with gfortran vs g77 which do not have compatible ABI either,
etc...
Indeed, but as I said before, this is a constrained environment.
Ubuntu 8.04 or 10.04, each with a controllable list of installed
packages. With Windows and MacOSX, python packagers seem to go the route
of statically linking anyway...
