John Williams commented on IVY-383:
-----------------------------------
My patch helped, but not enough...
I'm stuck trying to deal with the fact that Ivy tries to resolve conflicts
before it has a version number for everything. This only appears to be a
problem when the same module is both a direct dependency and an indirect
dependency and the indirect dependency is discovered first. For instance,
suppose module C has been published with revisions 1.0 and 1.1, and B has been
published with a dependency on C where rev=1.0. Now suppose module A depends
on B and C with rev=[1,). You would expect A to use C with rev=1.1, but if B
is listed first in the dependencies, [1,) will be evicted by 1.0; by the time
[1,) is resolved to 1.1, it's too late!

> LatestRevisionStrategy seems to compare both revision numbers and revision
> number patterns, but the implementation of patterns broken. For instance,
> patterns like "1.0+" are treated specially, but patterns like "[1.0,)" are
> treated like literal revision numbers! I have a case in which this causes
> conflict resolution to produce incorrect results. I'll hopefully be posting
> a patch soon to fix the particular resolution problem I've found, but I'm
> suspicious that there are other cases in which patterns are erroneously
> passed to LatestRevisionStrategy.
