Hi guys, I have a well-known problem. I just don't have all filesystems available for testing. What I need are testers for a certain, very simple functionality on any filesystem you can get hold of. I tested it locally on NTFS and FAT, as well as CDFS, as well as on 3.x Samba and via NFS. I tested from W2K, W2K3 and W7. I would be very interested to learn if this functionality is supported by other filesystems as well. Testing is simple. Attached you'll find the source code of a very simple testcase which calls certain native NT functions. For ease of use, the application allows to enter a Cygwin POSIX path and converts that to native NT notation by itself. You have access to AFS, MVFS, NWFS, NcFsd, Netapp, UDF, UNIXFS, SUNWNFS, any CIFS or old Samba versions? Please test! Also, if you try it on local or remote NTFS or FAT filesystems and it fails, I'd like to see the results. For testing, run the application twice per filesystem, one time for a directory, one time for a file. Also, please report your OS version per the output of `uname -s'. It's possible that different OSes show different results. So, here's how you do it. Build it like this: $ gcc -o test-qfif test-qfif.c -lntdll Then test for existing local dir and file: $ uname -s CYGWIN_NT-x.x $ /usr/lib/csih/getVolInfo //server/share Device Type : 7 Characteristics : 20 [...etc...] $ ./test-qfif /cygdrive/d/dir /cygdrive/d/dir/file NtQueryFullAttributesFile(\??\D:\dir) by name works NtQueryFullAttributesFile(\??\D:\dir) by handle works NtQueryFullAttributesFile(\??\D:\dir\file) by name works NtQueryFullAttributesFile(\??\D:\dir\file) by handle works Or for a share (with example for a failure): $ uname -s CYGWIN_NT-x.x $ /usr/lib/csih/getVolInfo //server/share [...] $ ./test-qfif //server/share //server/share/file NtQueryFullAttributesFile(\??\D:\dir) by name works NtQueryFullAttributesFile(\??\D:\dir) by handle fails, status code 0xc000000d NtQueryFullAttributesFile(\??\D:\dir\file) by name works NtQueryFullAttributesFile(\??\D:\dir\file) by handle works Thanks for your help, Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Project Co-Leader cygwin AT cygwin DOT com Red Hat
