It is disabled on the public servers (specifically, whenever the "create accounts" is enabled) because it is a blocking operation, i.e the entire notebook is unresponsive until the operation is finished. It can take several minutes to tar up a dozen Sage worksheets (in part because they contain all history) and it wouldn't be a good idea to make it so easy to freeze up the entire public notebook for long periods of time. See http://trac.sagemath.org/sage_trac/ticket/5952 (and there was a discussion of this in the lists at the time). There's no technical obstruction to making it non-blocking, it just hasn't been done yet. - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
