Hi users and devs,
I would like to have your opinion on the topic of case sensitive vs case
insensitive and which one you prefer in XWiki.
Currently, XWiki is case sensitive. This means the same resource name
(document name, space name, etc) can be written with either small letters
or big letters or a mix.
Examples: You can have both "Main.Test" and "Main.test" as 2
different
documents. Also, you can have "XWiki.Admin" and "XWiki.admin" as 2
different users. This also applies to URLs, as "/Main/Test" is different
from "/Main/test" or "/main/test", so all these 3 are different
resources.
Even from this short description, one can already identify possible
problems of this approach.
From the top 3 operating systems (Linux, Mac an
Windows), only Linux is
case sensitive, the other two (more user-focused Operating
Systems) are
both case insensitive.
Since XWiki has one of its main targets the Enterprise users, it is safe to
assume that the correct approach would be to also be more user-focused and
simplify things and avoid confusions by being case insensitive as well.
Also, a quick search on existing issues validates the need for this
improvement:
http://jira.xwiki.org/issues/?jql=text%20~%20%22case%20insensitive%22
What do you think? Is it OK to keep XWiki case sensitive, or would you
prefer it case insensitive? Bring arguments.
I have also created a jira issue for this idea:
http://jira.xwiki.org/browse/XWIKI-11412 to track it in the future.
Thanks,
Eduard

Hi Edy,
thanks for your message. From a forward-looking standpoint, I 100% agree
with you that switching XWiki to case-insensitive would be a good thing to
do. I've seen others (as well as myself) be lost because they were going to
.../xwiki/bin/view/Main/Xyy instead of .../xwiki/bin/view/Main/XYY and
vice-versa. If we were to make the decision today, I can't see a good
reason why not to go case-insensitive, especially when targeting business
users.
However we're not starting from a blank slate. There might be (I don't know
that there is, but there might be) legitimate use cases for a page named
"Xyy" vs a page named "XYY", both in the same wiki. I'd like to
have a
better idea of the consequences of this change, as well an analysis of a
public site such as xwiki.org to see whether this could be causing
unforeseen and other unexpected issues. In other words: what could go wrong?
Thanks,
Guillaume

As far as I know, Mac can be either case sensitive or case insensitive (just
need to choose how you format your disk)*.
So we could do the same on XWiki and propose to choose between case sensitive
and case insensitive at the installation (a variable in xwiki.properties)? I'm
not against a case insentivity by default if I can switch it later.
* I have a Mac at home and mine is case sensitive but I configured it 2 years
ago. I don't know if, in the last 2 years, Apple decided to remove this choice
between case sentivity and case insensitivity.

Yes, indeed, but I would not call that "configurable", since it involves
formatting your drive and choosing a filesystem that supports case
sensitive/insensitive names.

At least for recent Mac computers, they come with a case insensitive FS by
default. This options is also recommended in their documentation, for
example when erasing and reinstalling your OSX:
http://support.apple.com/kb/PH18869 (Yosemite) or
http://support.apple.com/kb/PH14243 (Mavericks), etc.

Hi Guillaume,
Here's a quick snippet for detecting such cases in your current wiki:
http://extensions.xwiki.org/xwiki/bin/view/Extension/Case+insensitive+docum…
Use it to detect collisions/mistakes and to have a better understanding of
the problem. It is also useful to better understand the impact, if any, on
your wiki if we were to move to case insensitive only (i.e. see how many
pages would present problems and would have to be fixed, either manually or
automatically).
Thanks,
Eduard

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).

Marius

Right. I posted a similar comment on the Jira issue.
Another interesting idea I was just thinking about would be to add
uniqueness constraints in the database on lower(doc.fullName) for instance.
That would cover the creation step.
Regarding performance, I have found in some quick searches that uniqueness
constraints are also achievable through unique function-based indexes [1].
On both cases, we would have to investigate on the database support or
solutions for using a function like lower() for the database unique
constraint or the unique index.

Hi users and devs,
I would like to have your opinion on the topic of case sensitive vs case
insensitive and which one you prefer in XWiki.
Currently, XWiki is case sensitive. This means the same resource name
(document name, space name, etc) can be written with either small letters
or big letters or a mix.
Examples: You can have both "Main.Test" and "Main.test" as 2
different
documents. Also, you can have "XWiki.Admin" and "XWiki.admin" as 2
different users. This also applies to URLs, as "/Main/Test" is different
from "/Main/test" or "/main/test", so all these 3 are different
resources.
Even from this short description, one can already identify possible
problems of this approach.
From the top 3 operating systems (Linux, Mac an Windows), only Linux is
case sensitive, the other two (more user-focused Operating Systems) are
both case insensitive.
Since XWiki has one of its main targets the Enterprise users, it is safe
to
assume that the correct approach would be to also
be more user-focused
and
simplify things and avoid confusions by being
case insensitive as well.
Also, a quick search on existing issues validates the need for this
improvement:
http://jira.xwiki.org/issues/?jql=text%20~%20%22case%20insensitive%22
What do you think? Is it OK to keep XWiki case sensitive, or would you
prefer it case insensitive? Bring arguments.
I have also created a jira issue for this idea:
http://jira.xwiki.org/browse/XWIKI-11412 to track it in the future.
Thanks,
Eduard

Hi Marius,

Not really, the problem you will have is that lower is not going to do
it's job because you are not in the right locale. That means that you
might end up with the request thinking that two values are not equals
while if lower did its job properly it would have been. In XWiki side
we will apply the locale to String.toLower and we will get a different
result which means that you have cases where in the require two
document name are not equals but they are when you compare two
DocumentReference which might create many issues. 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.
Right. I posted a similar comment on the Jira issue.
Another interesting idea I was just thinking about would be to add
uniqueness constraints in the database on lower(doc.fullName) for instance.
That would cover the creation step.
Regarding performance, I have found in some quick searches that uniqueness
constraints are also achievable through unique function-based indexes [1].
On both cases, we would have to investigate on the database support or
solutions for using a function like lower() for the database unique
constraint or the unique index.
----------
[1]
http://stackoverflow.com/questions/3944840/create-unqiue-case-insensitive-c…
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.
Not sure a filter would be the solution, since queries should be
application-specific.
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).
Well, as long as we do something like lower(myValue) = lower(dbValue)
instead of myValue = lower(dbValue), we should be good, right? (i. e. apply
the same databse collation/logic on both the searched value and the db
value so that we never get a missmatch).
Thanks,
Eduard

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.

Of course, the other thing to do would be going the direction of helpful
suggestions:
1) When creating a resource (pages, spaces, wikis) we can propose resources
that already exist similar to the entered name. This solves both casing and
spelling issues. The point is to avoid creation of similar resources when
reusing would have been the best way to go.
2) When landing on a non-existing resource, we can suggest similar
resources instead of just showing the standard "resource not found"
message. This covers URL mistyping and outdated links.
Side Note: Perhaps we could do some sort of similar improvement to wiki
links that, when a document does not exist, directly point to edit the new
page. Instead, they could point to the wiki creation step with prefilled
form values and suggestions. Other ideas might exist here.
General example: User enters "test" and the UI suggests both "Test"
(casing) and "testing" (possible mistyping) existing resources.
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.
Thanks,
Eduard

Instead, they could point to the wiki creation step with prefilled
form values and suggestions. Other ideas might exist here.
Big +1 for these. Something like:
* Create page "test" -> "There is already a page named 'Test'.
Are you
sure you wan to create a new page?"
* Go to /Space/test -> "Did you mean 'Test'?" / "Are you
looking for
General example: User enters "test" and the UI suggests both "Test"
(casing) and "testing" (possible mistyping) existing resources.
We can use Solr.

I agree with that, but on the practical aspects, how often do you need to
have in the same folder all the following files:
- "test

- "Test"
?
Also, as Marius pointed out, the FAT/Windows filesystem is case sensitive,
it just has an uniqueness constraint, so you can name stuff however you
want to, just don`t have duplicates because you will quickly make a mess of

It's easy to use the above argument for various cases, however IMO our goal

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,
Marius

Even from this short description, one can already identify possible
problems of this approach.
From the top 3 operating systems (Linux, Mac an Windows), only Linux is
case sensitive, the other two (more user-focused Operating Systems) are
both case insensitive.

to

http://jira.xwiki.org/issues/?jql=text%20~%20%22case%20insensitive%22
What do you think? Is it OK to keep XWiki case sensitive, or would you
prefer it case insensitive? Bring arguments.
I have also created a jira issue for this idea:
http://jira.xwiki.org/browse/XWIKI-11412 to track it in the future.

http://lists.xwiki.org/mailman/listinfo/devs 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).

From the top 3 operating systems (Linux, Mac an Windows), only Linux is
case sensitive, the other two (more user-focused Operating Systems) are
both case insensitive.

to

Well, yes. In Windows you will always have frustrations when making it work
with other systems that don`t have uniqueness constraints, so it`s obvious
you will have problems.
In XWiki`s case, at some point you should not have a XAR with 2 documents
with different casing in the same space, except if dealing with older
versions. (migrations from other wiki systems is another case when you
might hit this). For attachments I was not proposing an uniqueness
constraint since the collision chance is higher (files coming from
different folders on the user's HDD end up in the same space, so
c:\test.txt and d:\Test.txt both end up in Main.SomeDocument => collision).
Also, it's easy to spot a collision on an attachment since you see the list
of attachments you have uploaded. When creating a document, your focus is
narrowed and you don`t really see documents "around you".
Anyway, your points are valid and I agree that we should probably just
avoid all the confusion caused by this costly transition.
I guess the UI suggestion improvements is the only thing we are left with
at the moment.
Sure, we could try adding uniqueness constraints just at an UI level, which
could also be configurable, while the platform would remain free to do
whatever it wishes, just as long as the UI is always aware that duplicates,
even if not allowed to, could still exist. Of course, being an UI thing, it
would not be guaranteed, even if enabled, since each application could do
whatever it wishes in its UI or its components; so more of a "hit or miss"
if anyone tries to enable it.

Eduard
