Is your file in dropbox? I've noticed some syncing apps can butcher xattr's, which is how I found this in the first place.<div class="mailbox_signature">— Sent from <a href="https://www.dropbox.com/mailbox">Mailbox</a> </div> <div class="gmail_quote">On Thu, Jul 24, 2014 at 5:22 PM, Justin R.

I don't know if it's due to xattr being altered by something in the background, but it does seem to happen a lot. --- Justin Slepak PhD student, Computer Science dept. ----- Original Message ----- From: Spencer Florence <florence@northwestern.edu> To: racket <users@racket-lang.org> Sent: Thu, 24 Jul 2014 16:43:39 -0400 (EDT) Subject: [racket] DrRacket, OSX, and xattr Hi all, Whenever I save a file with DrRacket on OSX, it always sets some extended attributes on the file. Specifically it sets: [snips:pl7/examples] xattr -l somefile.rkt com.apple.FinderInfo: 00000000 54 45 58 54 44 72 53 63 00 00 00 00 00 00 00 00 |TEXTDrSc........| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000020 In addition if I clear the xattr's (via xattr -c) DrRacket treats this as an external write to the file and prompts me to overwrite on save and revert on run. Is this behavior intended? It seems odd given that DrRacket doesn't do this with normal attributes (permission, suid bit, etc.) If it is intended what is the rational and can I disable it? --Spencer ____________________ Racket Users list: http://lists.racket-lang.org/users </blockquote></div>
