A user reported the following error when attempting to upload an attachment. By changing their comment from Webb ECR to Webb, the upload became possible.

Follow up

I'll bet this is the Unix version of QuotesInAttachCommentError. The root cause is discussed in SearchFailsIfSingleQuoteIncluded. The problem is related to improper quoting of user data passed to external programs. Note the doubled single quotes in the example. I wonder if she entered 'Webb ECR' and not Webb ECR.

Also my guess is when she reentered the comment with Webb she left off the quotes since there was no space in the comment to quote. If she didn't enter quotes then then there is something wrong with that TWiki installation that is requoting text.

After reading your comment I asked the user, and she said no quotes of any kind were used

Sigh, no single quotes huh? Have you tried uploading another file with a two word comment? Does that work correctly? Can the user reproduce the bug at will? Can you get the user to try reproducing the bug on a sandbox topic on twiki.org?

-- JohnRouillard - 17 Aug 2002

I have since duplicated the error, and it only occurs with single quotes (as you correctly stately earlier). I now conclude that the user wasn't aware that she used single quotes when I asked her.

Thanks for the help
