Subject: [Openstack] Comparing roles - case (in)sensitivity<br>
<br>
<br>
<br>
tl;dr - Should we compare roles as case-sensitive or case-insensitive? I vote case-sensitive.<br>
<br>
This bug was recently filed in Glance: <a href="https://bugs.launchpad.net/glance/+bug/1010519" target="_blank">https://bugs.launchpad.net/glance/+bug/1010519</a> . It points out that Nova and Keystone are both case-insensitive when it comes to role comparison, yet Glance *is* case sensitive. I'm in favor of moving other projects to a case-sensitive approach for two main reasons:<br>
<br>
<br>
1) If a role is a string, and comparing strings is inherently case-sensitive, then role comparison would logically be case-sensitive<br>
2) I get to do less work<br>
<br>
<br>
<br>
Thoughts?<br>
