Run postinstall for dependencies before dependents #359

The resolver places dependent shards before dependencies, but postinstall script for the dependent shard may depend on the postinstall script in its dependencies having been run first.

For example, my grpc shard depends on protobuf, and both of them have executables they install (built via shards build), but installing them in this order results in this output (the shards command from the app and the shards build command in the grpc shard are both using -v here):

Sounds good by me. Wouldn't hurt to add an explanation to the comment.

I agree with the change, but we need a spec first.

The specs don't seem to run correctly on my machine, so I didn't know how I should test it:

This includes what appears to be the only place this particular class is tested. It makes it hard to know if a spec I wrote would be correct. :-\

Did you run make test or make spec? Can't remember which one is it

Oh, I was running crystal spec. make test does result in a successful run, but it looks like it's doing basically the same thing — it explicitly builds the binary, but I'd already done that. It looks like you can't run the unit and integration specs in the same run.

Either way, now that I know how to get a passing run I can try to come up with a spec. Any tips y'all have would be super helpful, since it looks like this is only done in an integration spec.

I'm not sure this actually fixes the issue.

Unless molinillo returns dependencies in some specific order, I see little reasons why the installed array of dependencies would be properly ordered. Your dependencies end up in some order where it fails. Reversing workarounds the issue, but that's about it. There is no guarantee that the postinstall script of nested dependencies will be built before parent dependencies in the tree.

@ysbaddaden It looks like molinillo stores dependencies in a hash. First-order dependencies are inserted up front and nested dependencies inserted during resolution. When it collects the packages, it iterates over that hash, which maintains insertion order. Do you have an example of a scenario where iterating in reverse does not fix the problem?

I'm afraid this doesn't solve the issue. If you have a shard.yml with both grpc and protobuf, depending on which dependency you declare first, the result will be sorted differently. So, no, this is not the solution.

Actually dependencies form an acyclic graph, so doing a topological sort is possible. Or, a more naive approach would be loop through the dependencies multiple times, skipping those with sub-dependencies still not installed, until all of them are done. Let me know if you want to take care of that. Otherwise, just open an issue and I'll take care of it.

Oof, you're right. I added protobuf to my app's shard.yml before grpc and, sure enough, same error.

Let me know if you want to take care of that. Otherwise, just open an issue and I'll take care of it.

Unfortunately, this PR is the first time I've looked into the internals here and it took 2 hours before I arrived at reverse_each, so I think you'll have a much easier time with this than I would. I'll go ahead and open an issue. Thanks for your help @waj!
