144929 - Using Rename Folder to change case throws alert

Status: VERIFIED DUPLICATE of bug 92165

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Julian Carver]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc2) Gecko/20020510
BuildID:    2002051009

When trying to use rename folder to change the case of a folder name, eg from
'It' to 'IT', it gives the alert "A folder with that name already exists. 
Please enter a different name.", and it won't let me change the case.

Reproducible: Always
Steps to Reproduce:
1.Create a new mail folder called 'It'
2.Right click on the folder and choose Rename Folder
3.In the small dialogue box change the lowercase 't' to uppercase 'T'



Actual Results:  An alert is shown:
"A folder with that name already exists.  Please enter a different name."
and the change cannot be made.

Expected Results:  It should have let me change the case for the mail folder name.

It seems it's doing a check when folders are created or renamed to prevent
duplicates, and is getting hung up on itself...

I can confirm this also happens on Win98, Build ID: 2002053012 (1.0).  Yeah,
maybe it's been fixed since then, we're both using old builds, but I'll test it
on Linux tomorrow at work, rather than risk borking W98 completely with a beta
Mozilla build ;)

Reconfirming that this is still happening on nightly build 2002081208 on Red Hat
7.2.

I think there are two separate but similar bugs here:

1.  When checking a folder name against other folder names to avoid duplicates,
mailnews should not check against the name of the folder being renamed, as that
name will disappear in the process of renaming.

Note that this bug is independent of case, as can be seen when you try to
execute a rename that doesn't change anything, neither the name nor the case. 
Just click on "rename folder", and then hit ENTER.  This rename, although silly,
would not cause a problem since it doesn't change the state of the folders in
any way.  So there should not be an error message.  But instead the "A folder of
that name already exists" alert is thrown.

Fixing this would fix the problem described in this bug.  

2. The other issue is, should it be permissable to have two folders whose names
differ only by case.  If so, then the rename check should be case-dependent, and
this is a separate bug.  If not, then the case-independence of the renaming
check is not a problem, and only problem 1. exists.

This is a dup of bug 92165.
