Hello Cygwin Team, We are upgrading Cygwin from 1.7.31 32 bit to 3.6 64 bit.
With the earlier version, 'cp -fp' command used to work without any error. Now, we get an error like, 'cp: preserving permissions for <file_name> not supported. Here is my understanding about ACLs & File permission in Cygwin: Windows ACLs will be translated/mapped to POSIX like in Cygwin (This includes user, group & permissions). Cygwin uses some logic to implement this (using Solaris API, using SFU, ACEs accumulated for the 'access allowed' etc.) I understand that, POSIX style is introduced from version 1.7.34. If my understanding is correct, prior to version 1.7.34, it was using UNIX like permission(not POSIX). In both cases (UNIX/POSIX), permission preserve has no real meaning. To disable this translation(to UNIX/POSIX), we had to set 'nontsec' CYGWIN variable in old Cygwin and we have to set 'noacl' in /etc/fastab for the new Cygwin But my question here is, 'cp -fp' was working with Cygwin 1.7.31. Why it is NOT working now with Cygwin 3.6? Note: We were NOT using 'nontsec' before & now, it's equivalent 'noacl' is also not used. If I use 'noacl' in the cygwin, 'cp -fp' doesn't complain.
