Description

We have setup Redmine 2.3.3 on CentOS and MS SQL 2008, running on Rails 2.0.-p247 (but also tested with Rails 1.9.3).
I have tested without any plugin.
I created the DB from scratch with redmine MIGRATE commands.
I created a new project, with one version and one category.

Then,
1. I added 15 bugs, all containing "mot clé" in the description.
2. I entered "mot" in the search area (top right of redmine screen)

Results: I got a page listing 10 bugs from "Bug 11" down to "Bug 02".

Expected results: start with "Bug 15" on top.

If I look in debug logs, I can see the following requests:

Whereas when I do it on a MYSQL database, I get the correct results, and the query to search for issues sorts by "issues.id DESC", correctly as expected (shown here on keyword "gps" with a database filled with several issues) :

Updated by Olivier Houdas over 11 years ago

The bug seems to happen in Ruby ActiveRecord SQL adapter 3.2.12:
in

activerecord-sqlserver-adapter-3.2.12/lib/arel/visitors/sqlserver.rb

in

def visit_Arel_Nodes_SelectStatementWithOutOffset(o, windowed=false)

lines 149 to 152:

orders = orders.map do |x|
            expr = Arel.sql projection_without_expression(x.expr)
            x.descending? ? Arel::Nodes::Max.new([expr]) : Arel::Nodes::Min.new([expr])
          end

  • Status changed from New to Resolved

For those interested, I tried a fix in the Ruby On Rails SQL server adapter:
https://github.com/rails-sqlserver/activerecord-sqlserver-adapter/issues/286

In activerecord-sqlserver-adapter-3.2.12/lib/arel/visitors/sqlserver.rb, I changed the line 151:

x.descending? ? Arel::Nodes::Max.new([expr]) : Arel::Nodes::Min.new([expr])

to

if x.descending?
              Arel::Nodes::Max.new([expr])
              groups += [expr]
              Arel::Nodes::Descending.new([expr])
            else
              Arel::Nodes::Min.new([expr])
            end

This fix has been working without showing visible bugs over the last 3 months. We have 20 active users, over 20000 issues/tasks in our database, and we use Gantt and Roadmaps as well as of course Filters and the global search.

Note that this is fixed with Redmine 3.x, which uses Rails 4.2, which includes an ActiveRecord SQL adapter which changed that part of the code, and does not have the bug anymore.

This issue should be closed.
