447746 - Rename Folder rejects case changes

Status: VERIFIED DUPLICATE of bug 92165

(Thunderbird :: Mail Window Front End, defect)

Description

[Douglas G. Danforth]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: version 2.0.0.14 (20080421)

It is not possible in one step to rename a folder which only changes the case of the folder name.  The error message generated is
"A folder with that name already exists.  Please enter a different name."

For example:
Innocentive => InnoCentive

One must do a two step process
Innocentive => grabage
garbage => InnoCentive

I consider this bad design and a definite bug.

Reproducible: Always

Steps to Reproduce:
1.
2.
3.


Expected Results:  
One should in one step be able to rename a folder which just a case change
e.g.
Innocentive => InnoCentive


This is a design flaw where, I assume, the input is converted to, say, lowercase, and then compared to all folder names also in lower case BUT the actual displayed name is not converted.

Hence one needs to remove the conversion step for folder name comparisons.
This allows there to be multiple folders with names such as

ABC
ABc
AbC
Abc
etc.

I'm experiencing the same behavior as described above, i.e. I need to run a two step rename process.

However, in contrast to the above proposal I wouldn't go as far as making folder names case-sensitive. Without having looked at the code I would suggest to simply drop the folder which is currently being renamed, from the list of existing folders, essentially by-passing the comparison to the same folder name. Just a suggestion and it might not even prove to be a good one after taking a look at the code...
