Make core.sharedRepository work under cygwin 1.7
When core.sharedRepository is used, set_shared_perm() in path.c needs lstat() to return the correct POSIX permissions. The default for cygwin is core.ignoreCygwinFSTricks = false, which means that the fast implementation in do_stat() is used instead of lstat(). lstat() under cygwin uses the Windows security model to implement POSIX-like permissions. The user, group or everyone bits can be set individually. do_stat() simplifes the file permission bits, and may return a wrong value. The read-only attribute of a file is used to calculate the permissions, resulting in either rw-r--r-- or r--r--r-- One effect of the simplified do_stat() is that t1301 fails. Add a function cygwin_get_st_mode_bits() which returns the POSIX permissions. When not compiling for cygwin, true_mode_bits() in path.c is used. Side note: t1301 passes under cygwin 1.5. The "user write" bit is synchronized with the "read only" attribute of a file: $ chmod 444 x $ attrib x A R C:\temp\pt\x cygwin 1.7 would show A C:\temp\pt\x Signed-off-by: Torsten Bögershausen <tboegi@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
