Hi All, I'm not sure when this cropped up, but it happened sometime after the great "win 9x" code purge. The problem is that the Cygwin dll no longer decodes or encodes file/directory names on managed mounts.
Steps to reproduce (WinXP SP2 x32): ----------------------------------- 1) mkdir -p /usr/src2 2) mount -b -s -o managed C:\\cygwin\\usr\\src2 /usr/src2 3) cd /usr/src2 4) mkdir -p FOO 5) ls -1 /cygdrive/c/cygwin/usr/src2 1.5.25(0.156/4/2) results: -------------------------- Expected: %46%4F%4F Actual: %46%4F%4F 1.7.0(0.179/4/2) results: ------------------------- Expected: %46%4F%4F Actual: FOO For this test, I setup a fresh, default Cygwin install on another machine. The Cygwin dll which was used was from the 1.5.25-7 package. I ran the test and everything worked as expected. However, on the machine with the Cygwin dll compiled from cvs HEAD, it did not. Running strace on the "mkdir -p FOO" operation seems to confirm that the munging gets skipped somewhere in the normalize_posix_path function. strace snippet from 1.5.25(0.156/4/2): -------------------------------------- [main] mkdir dll_crt0_1: user_data->main 0x4012A0 [main] mkdir __set_errno: void dll_crt0_1(void*):946 val 0 [main] mkdir normalize_posix_path: src FOO [main] mkdir cwdstuff::get: posix /usr/src2 [main] mkdir cwdstuff::get: (/usr/src2) = cwdstuff::get (0x22C740, 260, 1, 0), errno 0 [main] mkdir normalize_posix_path: /usr/src2/FOO = normalize_posix_path (FOO) [main] mkdir mount_info::conv_to_win32_path: conv_to_win32_path (/usr/src2/FOO) [main] mkdir set_flags: flags: binary (0x2) [main] mkdir mount_info::conv_to_win32_path: src_path /usr/src2/FOO, dst C:\Cygnus\cygwin\usr\src2\%46%4F%4F, flags 0x80A, rc 0 __________________________^^^^^^^^^ [main] mkdir symlink_info::check: GetFileAttributes (C:\Cygnus\cygwin\usr\src2\%46%4F%4F) failed [main] mkdir geterrno_from_win_error: windows error 2 == errno 2 [main] mkdir symlink_info::check: GetFileAttributes (C:\Cygnus\cygwin\usr\src2\%46%4F%4F.lnk) failed [main] mkdir geterrno_from_win_error: windows error 2 == errno 2 [main] mkdir symlink_info::check: 0 = symlink.check (C:\Cygnus\cygwin\usr\src2\%46%4F%4F, 0x22C400) (0x80A) [main] mkdir mount_info::conv_to_win32_path: conv_to_win32_path (/usr/src2) [main] mkdir set_flags: flags: binary (0x2) [main] mkdir mount_info::conv_to_win32_path: src_path /usr/src2, dst C:\Cygnus\cygwin\usr\src2, flags 0x80A, rc 0 [main] mkdir symlink_info::check: not a symlink [main] mkdir symlink_info::check: 0 = symlink.check (C:\Cygnus\cygwin\usr\src2, 0x22C400) (0x80A) [main] mkdir path_conv::check: this->path(C:\Cygnus\cygwin\usr\src2\%46%4F%4F), has_acls(1) [main] mkdir build_fh_pc: fh 0x61169E30 [main] mkdir alloc_sd: uid 1010, gid 544, attribute 41FF [main] mkdir cygpsid::debug_print: alloc_sd: owner SID = S-1-5-21-1454471165-492894223-1957994488-1010 [main] mkdir cygpsid::debug_print: alloc_sd: group SID = S-1-5-32-544 [main] mkdir alloc_sd: ACL-Size: 148 [main] mkdir alloc_sd: Created SD-Size: 212 [main] mkdir mkdir: 0 = mkdir (FOO, 511) strace snippet from 1.7.0(0.179/4/2): ------------------------------------- [main] mkdir dll_crt0_1: user_data->main 0x4012A0 [main] mkdir __set_errno: void dll_crt0_1(void*):931 val 0 [main] mkdir normalize_posix_path: src FOO [main] mkdir cwdstuff::get: posix /usr/src2 [main] mkdir cwdstuff::get: (/usr/src2) = cwdstuff::get (0x22C750, 260, 1, 0), errno 0 [main] mkdir normalize_posix_path: /usr/src2/FOO = normalize_posix_path (FOO) [main] mkdir mount_info::conv_to_win32_path: conv_to_win32_path (/usr/src2/FOO) [main] mkdir set_flags: flags: binary (0x2) [main] mkdir mount_info::conv_to_win32_path: src_path /usr/src2/FOO, dst C:\Cygnus\cygwin\usr\src2\FOO, flags 0x80A, rc 0 __________________________^^^ [main] mkdir symlink_info::check: 0xC0000034 = NtQueryAttributesFile (\??\C:\Cygnus\cygwin\usr\src2\FOO) [main] mkdir geterrno_from_win_error: windows error 2 == errno 2 [main] mkdir symlink_info::check: 0xC0000034 = NtQueryAttributesFile (\??\C:\Cygnus\cygwin\usr\src2\FOO.lnk) [main] mkdir geterrno_from_win_error: windows error 2 == errno 2 [main] mkdir symlink_info::check: 0 = symlink.check (C:\Cygnus\cygwin\usr\src2\FOO, 0x224520) (0x80A) [main] mkdir mount_info::conv_to_win32_path: conv_to_win32_path (/usr/src2) [main] mkdir set_flags: flags: binary (0x2) [main] mkdir mount_info::conv_to_win32_path: src_path /usr/src2, dst C:\Cygnus\cygwin\usr\src2, flags 0x80A, rc 0 [main] mkdir symlink_info::check: not a symlink [main] mkdir symlink_info::check: 0 = symlink.check (C:\Cygnus\cygwin\usr\src2, 0x224520) (0x80A) [main] mkdir path_conv::check: this->path(C:\Cygnus\cygwin\usr\src2\FOO), has_acls(1) [main] mkdir build_fh_pc: fh 0x611E4C7C [main] mkdir alloc_sd: uid 500, gid 545, attribute 41FF [main] mkdir cygsid::debug_print: alloc_sd: owner SID = S-1-5-21-1292428093-813497703-1801674531-500 (+) [main] mkdir cygsid::debug_print: alloc_sd: group SID = S-1-5-32-545 (+) [main] mkdir alloc_sd: ACL-Size: 148 [main] mkdir alloc_sd: Created SD-Size: 212 [main] mkdir mkdir: 0 = mkdir (FOO, 511) Anyway, that's all I could come up with for now. Anyone else seeing this? I'll see if I can't do more later on this week when I have more time.
