Hi all, 24 hours has elapsed, so it’s time for another release of Utility Belt! In this episode, our intrepid heroes discover a shocking secret! Rails has a bug which clashes with Utility Belt: [http://gilesbowkett.blogspot.com/2007/12/utility-belt-vs-rails.html](http://gilesbowkett.blogspot.com/2007/12/utility-belt-vs-rails.html) v1.0.6 bravely and dashingly sidesteps this issue without responsibly or intelligently fixing it. (Maybe that part happens next episode.) – Giles B.

(To clarify, this release of Utility Belt doesn’t _trigger_ the bug in Rails any more, but the bug in Rails still exists. Hoping to find a fix soon.) – Giles B.

Hoping to find a > fix soon.) Hi Giles, I put ``` CONSTANT_FROM_IRBRC = 7 ``` in ~/.irbrc, and the constant is visible from the console but not from a controller in a regular request. Can you show a minimal way to get ~/.irbrc accidentally loaded by an applicaction? – fxn PS: I reply here because comments are closed in the blog. ---

I’m not seeing this problem either. I’m using Rails 2.0.1 and dozens of gems. I’ve used ack to scan all (I think) of the code and the only occurrences of ‘irb’ are related to consoles and breakpoints. I’ve put some code in my .irbrc file and that is not being run from inside rails. Are you sure Rails is the culprit here?

Hi Xavier, hi Bob, the bug is obscure and weird and I do not have any test cases yet. I know for a fact it’s in Rails. See the mail about “Constant already initialized” errors - basically, I saw it before with code that _only_ existed in my .irbrc and was not in any other file anywhere on my system. But that was months ago. It went away on its own and I don’t know why. I’ll post details on my blog at some point today. I’m not seeing it on my own installs either, but here’s a screencast of the bug in action: [http://screencast.com/t/k6Nlk8Q0Csy](http://screencast.com/t/k6Nlk8Q0Csy) Here’s a grab of the stacktrace: [![](http://s3.amazonaws.com/giles/rails_bug_stacktrace.png) ](http://s3.amazonaws.com/giles/rails_bug_stacktrace.png) (I’ll put those on the blog also. Actually, the screencast is already linked, but it’s in one of several posts. Orion E., who I quote in the latest post, stopped his Rails apps from crashing on him unexpectedly by removing the “edit” method in Utility Belt, see the latest post and his comment on Raganwald’s blog for more.) The relevant lib is ActiveSupport::Dependencies, it has a set of files to load and for some reason it’s gathered .irbrc into that list, either at or around line 488. That’s pretty much all I know at this point. The bug’s only been conclusively spotted in versions prior to 2.0, but the relevant code in 2.0’s active\_support/lib/dependencies.rb is in most cases identical. Re: blog comments, this is a friendly e-mail list where peer pressure will compel us all to be decent human beings. It takes energy and luck to get that in an online community - plenty of online communities don’t have it - and the blog format doesn’t have the necessary features to even encourage it, so I will _never_ re-enable comments on my blog. Blog comments are a bug. They often work out due to luck, but the design is terrible and makes all kinds of unscalable assumptions. But definitely get in touch with any and all ideas, I do appreciate it. There 's also a Utility Belt list, it’s removed\_email\_address@domain.invalid.
