Huh? > Cygwin devs at least aware of the serious problems with manipulating files > created by Cygwin (with share attributes) inside Vista's explorer? Yes. But it's a minor problem. It only affects files in the user's Windows homepath. All the rest of your drive(s) are not affected at all. And you should better create a Cygwin specific home dir anyway. > Every file with these share attributes take 1000's of times longer to > delete,move,copy > because of their shared-ness-- this seems like an issue that should be > looked > into for a project whose primary mission is Windows interoperability. Any You got something wrong. POSIX compliance is the primary mission. Windows interoperability is a nice extra. > Vista > issue with Cygwin should be considered a Cygwin issue by extension, > especially > serious usability issues like the above. So much for your opinion. In my opinion it's a terrible move by Microsoft to slow down every operation in the user's homepath so much just to look for the "Everyone" ACE and to visualize it's existence. Independently from Cygwin. > Now for the constructive part of my post: Is the following suggestion from > another thread on this issue not feasible to implement? > > http://www.mail-archive.com/cygwin@cygwin.com/msg84231.html > > Specifically, "I suggested that Cygwin changes it's > attribute handling to leave out the local/None and Everyone groups > completely, whenever they have no access permissions." No, it's not feasible. If you leave out the Everyone ACE, the permissions are not POSIX-like anymore. Leaving out means that others have no permissions at all. Not even to see the permissions. That's not correct from a POSIX POV. Even if others don't have rwx permissions, they need at least FILE_READ_ATTRIBUTES and READ_DAC permissions. This requires to have an Everyone ACE. And this is not a Cygwin-only problem, install SUA(*) and see what it does with respect to POSIX permissions and Everyone ACEs...
