This is the last test release if nothing unexpected happens. I plan to release officially on Friday. What's new: ----------- - New, unified implementation of POSIX permission and ACL handling. The new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and they allow to inherit the S_ISGID bit. ACL inheritance now really works as desired, in a limited, but theoretically equivalent fashion even for non-Cygwin processes. To accommodate standard Windows ACLs, the POSIX permissions of the owner and all other users in the ACL are computed using the Windows AuthZ API. This may slow down the computation of POSIX permissions noticably in some circumstances, but is generally more correct. The new code also ignores SYSTEM and Administrators group permissions when computing the MASK/CLASS_OBJ permission mask on old ACLs, and it doesn't deny access to SYSTEM and Administrators group based on the value of MASK/CLASS_OBJ when creating the new ACLs. The new code now handles the S_ISGID bit on directories as on Linux: Setting S_ISGID on a directory causes new files and subdirs created within to inherit its group, rather than the primary group of the user who created the file. This only works for files and directories created by Cygwin processes. - New mount type "usertemp" which allows to mount a POSIX directory to the Windows per-user temporary directory. - cygpath has a new -U option, which creates cygdrive paths using the unambiguous /proc/cygdrive prefix. - New API: rpmatch. What changed: ------------- - Align setfacl(1) usage a bit closer to the usage on Linux. Rename -d option to -x, --substitute to --set. Add --no-mask and --mask options. Allow to use the -b and -k option combined to allow reducing an ACL to only reflect standard POSIX permissions. - Fix (numeric and monetary) decimal point and thousands separator in fa_IR and ps_AF locales to be aligned with Linux. - utmpname/utmpxname are now defined as int functions as on Linux. Addresses: https://cygwin.com/ml/cygwin/2015-12/msg00320.html Bug Fixes --------- - Not a bug fix as such, but a workaround for new behaviour in Windows 10 version 1511 64 bit. This version introduces a problem which existed in a similar variation (just vice versa) in XP and Server 2003 64 bit as well. An unexpected stack arrangement when starting a 64 bit Cygwin application from a 32 bit application (e.g. 32 bit CMD.EXE) broke Cygwin's fork.
