I recently encountered a problem with the Dojo. My ISP refuses to allow access to the built dojo.js and dojo.js.uncompressed.js files. It seems their antivirus program thinks both of them could be mass-mailing worms. I can't access the files through the browser or open them for reading in an FTP client. I can only delete them.
I investigated the problem and found out that the file is rejected because it contains "getNamespace" string. If I replace all occurrences of "getNamespace" with "getNS" the file can be accessed fine. To be frank, I was surprised that it is so easy to be classified as a virus.
I'm not sure if the ISP can or will be willing to do anything about this. If not I will have to file a bug report for the Dojo and hope that developers will address it. In the worst case I might end up replacing the string manually when uploading a new Dojo version. I hope I won't have to do that, as there could be unforeseen side-effects.
