Description
Hello
Our users encountered an error in a specific case, when uploading files.
Here is a screenshot showing the 403-forbidden error after the upload:
Steps to reproduce¶
This error happens in a specific case when the user is not a member of the project.
Here are the steps to reproduce the issue:
- The current user is NOT member of any project
- The build-in role "non-member" has NO permission at all
- In the project's members tab, a role is set for the member "non-member" and this role has permission to create and update issues
Logs¶
On the server side, here are the logs:

- Target version changed from 4.1.2 to 4.2.0
Moving this to a major version (4.2.0) because the proposed patch moves a method from one class to another.

I have the same problem. I'm on :

I tried to add the tweak to user.rb like @Rob Logan did, but sadly it does not work for me :- (
It actually broke more and I have Internal Error instead now.
Any hints? I want to allow self-registered-authenticated users to attach attachments...

Can you check in the logs what error do you receive?

Vincent, what do you think about the following fix?
I tried to fix the method User#roles to include the roles assigned to Group Non Member or Group Anonymous Users groups. For example, roles_for_project already do this.
Also, only the roles assigned to public projects are included in the query.

Hello Marius. Thank you for this update.
About the fix, I think we should cumulate these roles.
A member should never have fewer permissions than a non-member ; a non-member should never have fewer permissions than an anonymous.
As I see it, a member should have all the permissions granted to these roles : member.roles + non_member.roles + anonymous.roles

roles_for_project (source:/trunk/app/models/user.rb#L637) doesn't do this, it overrides the roles only if the user is not a member. At the same time, being a global context, I agree that it makes sense to cumulate them or do cumulate the roles from public projects where the user is not a member.
Being a quite important design choice, I would like more feedback.
What do you think if I commit the fix just for this issue for now to catch the next releases and discuss more in a different issue?

I am against the change. I think it is confusing if the set of permissions for a role is different from as configured. And the change may damage the flexibility of permissions and roles.

It may actually be a different topic. I agree, we can first fix the bug with the 403 error, without modifying current roles' inheritance.
