Redmine

for example, when I try to check diff between source:/trunk/app/controllers/account_controller.rb@62 and source:/trunk/app/controllers/account_controller.rb@44 from http://www.redmine.org/repositories/changes/redmine/trunk/app/controllers/account_controller.rb, I'm getting above error.

/trunk/app/controllers/account_controller.rb doesn't exist at r62. That's why you get this error.
/trunk/redmine was moved to /trunk at r67.

Reopen if needed.

Thanks JP! Now I can understand what has happened.

Subversion can see the all of history if svn copy or svn move has been used for moving /trunk/redmine to /trunk.(svn shares the history between branches)

I think the shelling out difference between r44 and r66 in the history page of account_controller.rb should be as bellow.

>svn diff -r 44:62 http://redmine.rubyforge.org/svn/trunk/app/controllers/account_controller.rb@HEAD

Because the given path is based on HEAD, not a specific revision.
This gives the correct history even though the /trunk/app/controllers/account_controller.rb doesn't exist before r67.

We need to differ the case for specific revision and HEAD. It would be better to regard [@REV] as a part of path.

p.s. the link source:/trunk/app/controllers/account_controller.rb@62 giving same error message. but it seems natural becasue the path doesn't exist at revision 62.
