Hello,

I am experiencing a weird problem on one of the 3 test servers I’m  
using:  
There is a controller named admin/statistics and I am trying to  
access /admin/statistics  
The matching rule is: map.connect ‘:controller/:action/:id’  
On 2 of the 3 servers, recognize\_path correctly matches to  
Parameters: {“action”=\>“index”, “controller”=\>“admin/statistics”}  
But on the 3rd server here is what happens:  
Parameters: {“action”=\>“statistics”, “controller”=\>“admin”}  
Of course that action does not exist, and it fails.

Any idea of what could be causing that problem?

Thanks,

Paul Cahier

some more information  
I ran the following function to search more detail:

#To show all the routes and their recognition  
ActionController::Routing::Routes.routes.each do |route|  
puts route  
puts route.write\_recognition  
puts  
end

And to my great surprise, despite exactly the same source, rails  
version, ruby version, there was a difference:  
In the “bad” server:  
if (match = /\A/(?i-:(rails\_info|rails/info|public|rest|admin|admin/  
teams|admin/keywords|admin/photos|admin/car\_situations|admin/  
circuits|admin/statistics|admin/update|admin/communication|admin/  
users|admin/dump|admin/editor|admin/photo\_types|admin/updates|admin  
/photo\_styles|admin/monitoring|admin/database|admin/jobs|admin/  
people|admin/sponsors|admin/sessions|admin/import|admin/customers|  
admin/synchronize|admin/grand\_prix|admin/photo\_angles|admin/races|  
admin/posts|admin/settings|admin/emotions))(?:/?\Z|/([^/;.,?]+)  
(?:/?\Z|/([^/;.,?]+)/?))\Z/.match(path))

In the “good” servers:  
if (match = /\A/(?i-:(rails\_info|rails/info|public|admin/teams|admin  
/keywords|admin/photos|admin/car\_situations|admin/circuits|admin/  
statistics|admin/update|admin/communication|admin/users|admin/dump|  
admin/editor|admin/photo\_types|admin/updates|admin/photo\_styles|  
admin/jobs|admin/monitoring|admin/database|admin/people|admin/  
sponsors|admin/sessions|admin/import|admin/customers|admin/  
synchronize|admin/grand\_prix|admin/photo\_angles|admin/races|admin/  
posts|admin/settings|admin/emotions|rest|admin))(?:/?\Z|/([^/;.,?]  
+)(?:/?\Z|/([^/;.,?]+)/?))\Z/.match(path))

In other word rest|admin is added on the non-working servers too  
early…  
“Sounds like a print the node before the subnodes”

Any hints would be lovely,

Problem was solved, and comes from an error in actionpack:  
in /actionpack-1.13.3/lib/action\_controller/routing.rb line 290  
Dir["#{load\_path}/**/\*\_controller.rb"].collect is not a constant order  
depending on the file system, and apparently not the good order for  
checking for possible routings(since the regular expression to match  
routings is based on the order given by this).  
A simple fix is to add a sort:  
Dir["#{load\_path}/**/\*\_controller.rb"].sort.collect

After that everything works fine, and the order will be constant  
amongst filesystems.
