[PkgEval] LightGraphs may have a testing issue on Julia 0.4 (2015-06-30)

[IainNZ]

PackageEvaluator.jl is a script that runs nightly. It attempts to load all Julia packages and run their tests (if available) on both the stable version of Julia (0.3) and the nightly build of the unstable version (0.4). The results of this script are used to generate a package listing enhanced with testing results.

On Julia 0.4

• On 2015-06-27 the testing status was Tests pass.
• On 2015-06-30 the testing status changed to Tests fail.

This issue was filed because your testing status became worse. No additional issues will be filed if your package remains in this state, and no issue will be filed if it improves. If you'd like to opt-out of these status-change messages, reply to this message saying you'd like to and @IainNZ will add an exception. If you'd like to discuss PackageEvaluator.jl please file an issue at the repository. For example, your package may be untestable on the test machine due to a dependency - an exception can be added.

Why are some packages passing tests and some failing?

(Ah, is it a Distributions.jl thing?)

[IainNZ]

Yeah its Distributions, MathConst became Irrational in Base.

[sbromberger]

Gah. The only reason I was using Distributions was for sample() which is in StatsBase, so I guess I can switch. I wish there were a performant sampler built into Base, though.

[IainNZ]

Living on the edge is tough, thats why I don't use 0.4!

[sbromberger]

Yeah, looks like round() changed somewhere as well. Travis is spewing

ERROR: LoadError: LoadError: test error in expression: round((pagerank(g5))[3],3) == 0.318
DimensionMismatch("")

[sbromberger]

All fixed, I think. Appreciate your help.
