I've just set up a new machine with Cygwin (64bit w/ the 2014-06-23 13:20:35 snapshot), nsswitch.conf specifies "db" for both passwd and group (the files have been moved away just to be sure they aren't picked up). I have one share with somewhat strange ACL that I always had to use via a "noacl" mount option. I thought I should try again and this is what happened (bla is a file that has non-zero size and is owned by me):
(1014) > getfacl bla # file: bla # owner: gratz # group: Domain Users user::--- group::--- group:+Authenticated Users:rwx mask:rwx other:--- (1015) > [ -r bla ] && echo Hello... Hello... (1018) > perl -E 'say -R "bla" ? "yes" : "no"' no (1016) > perl -E 'say -r "bla" ? "yes" : "no"' no (1017) > perl -E 'say -O "bla" ? "yes" : "no"' yes So for whatever reason Perl still doesn't deal correctly with those ACL, while the shell test operator does. Now the kicker: if I run Perl under strace, the test succeeds... huh? 26 556465 [main] perl 5712 path_conv::check: this->path(\\share\bla), has_acls(1) 34 556499 [main] perl 5712 build_fh_pc: fh 0x18032C9F0, dev 000000C3 27 556526 [main] perl 5712 stat_worker: (\??\UNC\share\bla, 0x600039498, 0x18032C9F0), file_attributes 32 12380 568906 [main] perl 5712 fhandler_base::fstat_helper: 0 = fstat (\??\UNC\share\bla, 0x600039498) st_size=228, st_mode=0x81A4, st_ino=8320105424607096594st_atim=53A96650.28F3A48 st_ctim=528DB9A1.13F33938 st_mtim=528DB9A1.4EE2D30 st_birthtim=528DB9A1.44615F0 66 568972 [main] perl 5712 stat_worker: 0 = (\??\UNC\share\bla,0x600039498) 3210 572182 [main] perl 5712 fhandler_pty_slave::write: pty0, write(0x600082E00, 4) 27 572209 [main] perl 5712 fhandler_pty_slave::write: (656): pty output_mutex (0x184): waiting -1 ms 24 572233 [main] perl 5712 fhandler_pty_slave::write: (656): pty output_mutex: acquired yes Incredibly, this also works with the original script that led me onto this hunt. It runs a lot slower with all that stracing going on of course. Ideas?
