This would probably be the simplest to implement without significant
performance problems. However, this would be just UI candy and the platform
would be left the way it is, a free-for-all.

Pretty much the same comments here.
On personal side this is one of the thing I hate about Windows ("just
do what the hell I told you to do and don't try to be clever").
On technical side everyone should understand that this is a huge
refactoring that will produce regressions for at least one year.
Another things is that it's slower so performance are going to be
worst in most of the XWiki code.

I'm undecided. As a technical Linux user I
prefer case sensitivity, but I
can see why this is sometimes unexpected for non-technical users. I'm not
sure how you plan to implement this. I know this thread is not about the
technical aspects but still I think it's important to consider the cost
that this change will imply.
First, even for a case insensitive system, I think it's very important to
preserve the case entered by the user. For instance, If I create a user
with the alias 'myCoolAlias' then I wouldn't like to see
'mycoolalias'
displayed in the UI. Same, if I attach a file named
'myCoolPresentation.odp' then I want to see precisely that name on the
list
of attachments. So we need to store case
sensitive values in the
database.
The difference from now will be:
* when creating an entity: check that there's no other entity that has
the
same normalized reference
(toLowerCase/toUpperCase)
* when retrieving an entity: look for normalized references
This means we'll have to call toLowerCase/toUpperCase very often so we
need
proper database indexes. Otherwise we'll have
a performance impact.
Second, we have lots of places that query the database and since we have
to
store the raw case-sensitive values then we need
to update all this
places.
Moreover, since it's not about a single
field/column I'm not sure we can
write a query filter to lower the case automatically. Then we also have a
lot of extensions that query the database and that create entities. Those
will have to be updated too.
Lastly, AFAIK lower case and upper case are locale dependent. The 'lower'
query function doesn't have a locale parameter so it depends on the
locale
the database has been configured with. So there
can be cases when a user
won't be able to retrieve an entity using some locale dependent lowercase
version of the reference because the database computes the lower case
differently than what the user expects (because it uses a different
locale).
Thanks,
