Upgrade from Version 1.4.0 --> 1.4.2 introduces rb-gsl dependency, downgrades spreadsheet

[rdlugosz]

[As mentioned in my issue in the old repo]…

It appears that going from 1.4.0 to 1.4.2 creates some unexpected dependency changes that should not be a part of a Patch-level release:

1. The rb-gsl gem is now required. This is problematic on Heroku where it cannot be easily built.
2. The spreadsheet gem gets pinned to an older Minor release; on my app this mandated a downgrade of spreadsheet from 0.9.9 to 0.6.9. Not sure if this is intentional or matters, but it was surprising if nothing else.
3. If the minimization gem is not pinned to 0.2.1 a similar dependency is created with the bump to 0.2.2. I have opened an issue over there.

Here's a peek at the diff of Gemfile.lock when statsample ~> 1.4.0 and mimization = 0.2.1:

-    statsample (1.4.0)
-      dirty-memoize (~> 0.0)
+    statsample (1.4.2)
+      awesome_print
+      dirty-memoize
       distribution
-      extendmatrix (~> 0.3.1)
-      fastercsv (> 0)
-      minimization (~> 0.2.0)
+      extendmatrix
+      minimization
+      rb-gsl
       reportbuilder (~> 1.4)
       rserve-client
-      rubyvis
-      spreadsheet (~> 0.6)
-      statsample-bivariate-extension (> 0)
-    statsample-bivariate-extension (1.1.0)
-      distribution (~> 0.6)
+      rubyvis (~> 0.5.0)
+      spreadsheet (~> 0.6.5)

In commit 8ce01 I removed the dependency on rb-gsl and pushed a new version (1.4.3) to rubygems.

I also updated Minimization. Everything should be working right now. :P

Thank you for these issues!

Very cool, thx. Any thoughts on why the spreadsheet gem is being pinned to the 0.6 version? More of a curiosity, but previously we were at 0.9.9 and their most current release is 1.0.3.

[agarie]

Not really. I refactored statsample to use a gemspec instead of hoe and the rb-gsl dep was introduced by mistake -- I was using it anyway on my system and Travis already installed it. Thankfully you and other folks complained and it's fixed now. I had that version of spreadsheet installed here and it didn't break anything, so I pinned it.

I opened #29 to work on this. Nothing is broken right now, but leaving it outdated doesn't seem like a good idea...

Cool, thx!!
