Possible to ignore file extension capitalization?

Hi all,
We're running into the problem of file extensions having different capitalization, i.e. .PDF versus .pdf. Some users have reported issues updating files with different capitalization. Is there a way to ignore the file extension capitalization? Thanks!

Which OpenKM version are you using ?
Looking in the source code
Code: Select allString mimeType = MimeTypeConfig.mimeTypes.getContentType(name.toLowerCase());
Seems the identification of document type is case insensitive. The document name is always converted to lowercase ( all mime types definition provided by default are lowercase ) and then identified. Can you explain with more detail the behaviour, some screenshot is always wellcome for better understanding.

Our production instance is Version: 6.3.0 (build: 8156)
I'm verifying with my coworker what he was seeing.

Okay so my OKM instance treats files with different file extension capitalization as two different files and won't upload over the other one. I'm running a workflow that checks if a file exists and it currently treats them as different files as well. But the root cause of it is still that my OKM installation doesn't convert to lowercase. Where can change this attribute?

If I understood you have a file name "name.AAA" yet existing in the OpenKM and as a workflow process step you are trying to upload a file named "name.aaa", then it raises and error, is that ?
If this is your scenario, you can disable the filename check with the Administration > Configuration parameter named
Code: Select allsystem.document.name.mismatch.check=false

I know this option existed, but can't this potentially create an issue with being able to upload a file with the wrong name entirely, i.e. the wrong file?

Yes, enabling it solves a kind of problem but can create new ones. The other solution is modifying source code to force all documents name be lowercase. I can guide about how doing it.

Yeah that'd be great if we could do that! Well actually I think I can figure it out by modifying the vernum for all new files, but is there an "easy" way to do it for existing files?

Have two options:
Take a look at DbDocumentModule.java ( see create, rename and update , line 95, 331, 828)
Probably the easiest is modify PahtUtils class the method named escape:
Code: Select allpublic static String escape(String name) {
String ret = cleanup(name);
// Fix XSS issues
ret = Encode.forHtml(ret);
return ret.toLoweCase();
}
The problem is the method espace is executed from a lot of places, for example, creating folder etc... here you are forcing a lot of things to being lowercase.
