[graph][graph_parallel][disjoint_sets] Of dependencies and "pending" libraries.
In the process of creating Conan packages I ran into the rather strange "disjoint_sets" library. It's a library that has been "pending" for 18 years, AFAICT. I don't know what a pending status means for this. But for creating modular packages it means it's a giant PITA to deal with the the interdependencies of "disjoint_sets", "graph", and "graph_parallel". What I want to know is: 1. What is this hidden "disjoint_sets" library/module that only has two headers? 2. Why isn't "disjoint_sets" in the "graph" library tree, especially given that it's not an official library (AFAICT)? 3. Why is "graph_parallel" not in the "graph" library also? -- -- Rene Rivera -- Grafik - Don't Assume Anything -- Robot Dreams - http://robot-dreams.net

I do not know anything about disjoint_sets but graph_parallel was separated from graph because it represented depencendies which a user of graph need not have. BTW the maintainer of graph and graph_parallel has been absent for a long time now so maybe someone else would be willing to take over maintenance of both.

Okay.. I'll try and submit some PRs to move it soon. but graph_parallel was
separated from graph because it represented depencendies which a user of graph need not have.
That almost makes sense ;-) I say that because graph depends on graph_parallel. I know it doesn't if you don't happen to include some specific headers. But we've already gone over the module level dependency discussions. BTW the maintainer of graph and graph_parallel has
been absent for a long time now so maybe someone else would be willing to take over maintenance of both.
I'll see if I can write up a post requesting maintainers. Rene.

As far as I can see, Graph includes headers from Graph_parallel only when BOOST_GRAPH_USE_MPI is defined.

Interesting.. but doesn't help the module level dependency problem. Maybe those graph mpi headers should move to graph_parallel? Rene.
