Conda proposal: virtual hotfixing via build groups
In this note, I propose a modification to
conda and to its implied package specification that will provide, in my view, a solution to a common pitall of the
conda ecosystem, and will provide additional performance benefits as well.
conda, as with many package ecosystems, it is often necessary for a package to place version constraints on its dependencies to ensure that they interoperate properly. In practice, such constraints must balance two competing concerns:
- if the constraints are specified too tightly, then packages will often unable to coexist, because their version constraints will conflict. For example, if package
B <2.0, and package
B >2.0, then packages
Ccannot coexist. The tighter the constraints, the more likely this is to happen.
- on the other hand, if the constraints are specifed too loosely, then packages will often break if one of their dependencies ce
