Program with which you had the problem:
attach
Name of person who discovered the bug: Ed Moriarty
Their MIT phone number: 253 0958
Their MIT address: 35 - 4??
Their Athena Login ID: mory
Name of person reporting bug: Craig Hicks
------------------------------------------------------------------------
A brief synopsis of the problem:
If one person has logged in at a work station and attached a directory
with attach -n, and another person logs in and wants to attach without
the -n option, s/he is overridden.
------------------------------------------------------------------------
Please describe the problem in detail (mention any necessary files or
commands that may be involved, on which machine the bug happened, and what
the program did that was wrong):
when 2 people are logged in at the same workstation, neither
can detach a directory.
If attach -n has been used to attach a group directory, only the
creator of the top level directory can write at all. Furthermore, s/he can
only write to those directories that s/he has created.
------------------------------------------------------------------------
Repeat by (please enter a set of commands which will allow us to
repeat the bug):
1 person logs in remotely to a workstation and attaches a group
directory of which s/he is owner. Attach with -n optyion.
Next person logs on to machine and tries to attach same group
directory. Should say 'already attached'. Now thaty second person cannot
write to group directory.
------------------------------------------------------------------------
Fix (if you know what it is):
