Description Andrew Kongs 2013-02-26 16:50:22 UTC 
When attempting to upload a CSV file, MediaWiki throws the following error:

"File extension ".csv" does not match the detected MIME type of the file (text/plain)."

This forces the user to change the file extension from ".csv" to ".txt" in order to store this file in the wiki, which is incorrect

Tested with CSV from various programs, including Microsoft Excel export.
Comment 1 Andre Klapper 2013-02-26 19:48:05 UTC 
From which operating system is the csv file uploaded?
Comment 2 Andrew Kongs 2013-02-26 21:10:24 UTC 
Tried this on both Mac OS X (10.8) with chrome and Windows 7 with firefox.

Its matters more what os your server is as file type detection is done on the server side. (Sometimes mw uses the underlying os for file type detection. Im not sure what the default is off the top of my head)

Mw hasnt overly been tested with file formats other than standard image formats so its probably just an oversight.


(As quick hack work arround - if its important to make this work quickly you could change csv to be associated with text/plain in includes/mime.types . Obviously that is not a proper fix)

have the same issue with Windows 2012. as well as 

File extension ".xlsx" does not match the detected MIME type of the file (application/vnd.ms-excel).

File extension ".docx" does not match the detected MIME type of the file (application/msword).
Comment 6 Sam Reed (reedy) 2013-08-05 13:52:21 UTC 
docx is application/vnd.openxmlformats-officedocument.wordprocessingml.document
xlsx is application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
