Stack work vs revisions

[kgadek]

Coming from #337 , we set resolver: ghc-7.10 and specify dependencies in extra-deps.

We had PR'd Kmett's nats to relax upper-bound from base < 4.8 so it would work with GHC 7.10. It's probably worth seeing: ekmett/nats#10 (comment)

Note: It is very likely that you'll run into more issues of this sort if stack isn't capable of disambiguating dependencies by compiler version.

Anyway.

The issue here is that stack doesn't appear to support revisions (x-revision in .cabal file). How would one specify that want package X.Y.Z revision N?

[snoyberg]

Huh, it looks like my previous message didn't go through.

stack definitely does support revisions from Hackage. Perhaps you need to run stack update to download the latest revisions?

[kgadek]

What would I need to do if I wanted to have nats-1 in initial revision 0 as opposed to revision 1?

[snoyberg]

That's not supported, but I'm not sure why you'd want to do that.

I imagine a scenario where latest revision changes dependencies in a way that breaks builds, so one would like a previous version.

That's not a common use-case though.

[snoyberg]

I don't think stack should make any change here: it's properly reflecting the way upstream Hackage is working. We can question the wisdom of this approach by Hackage (I have in the past), but nonetheless that's the situation we're in.

@snoyberg I believe revision 1 of MonadRandom-0.3.0.2 broke LTS-2.22. What can be done to fix this?

[snoyberg]

I'd report it to Brent, if the build was working previously, this change is
a mistake.

I reported the issue: byorgey/MonadRandom#15

[kgadek]

Meantime, what can be done to mitigate such problems in the future?

[snoyberg]

The problem's been fixed upstream. For future occurrences: I've added an allow-newer config option to master, which will ignore these kinds of situations.

[kgadek]

For future reference: f359cbe

[snoyberg]

Actually, if you could also test out df54339 (without using --allow-newer), I'd appreciate it.

[kgadek]

Difficult to test now that MonadRandom is fixed. As soon as any kind of similar problem will occur, we'll try that. Thank you :)

[snoyberg]

Hopefully next time this happens you won't even notice ;-)

@snoyberg This works for me now (I installed with git yesterday) and I was getting these errors with the random package.

[mwu-tow]

I'm not sure if it works properly.

I'm using stack from master ff45507. When I tried to build a package depending on MonadRandom I got the following:

Making stack update magically solved the issue. However, it seems to be fixed rather by the MonadRandom update that removed problematic constraint rather than by stack.
Still, I'm not sure if it is actually the case — just thought it might be good to report this.

Here is another example where the patch doesn't work (Stack version 1.7.1):

    setup: At least the following dependencies are missing:

The problem seems to be, that while the above patch makes stack accept the out of range dependency it doesn't make cabal do so too. So cabal fails when it encounters the contradictory dependency bound tagged >= 0.8.5 && <1 && ==0.8.2.

[mgsloan]

@janpath Ah, yes, this probably means that stack now needs to pass --exact-configuration into the configure invocation.
