Set up like this, `ls' seems to be able to read directories (readdir returns 0) but seems to have some sort of character-set disagreement with the far end, with the result that the `strace' output becomes incredibly messy when the `lstat' calls fail on files whose names appear to consist of the right number of `?' for their length. At the end of the directory, I see --------------------------------------------------------------- 57 108833 [main] ls 4200 fhandler_disk_file::readdir: NtQueryDirectoryFile failed, status 0x80000006, win32 error 18 49 108882 [main] ls 4200 geterrno_from_win_error: windows error 18 == errno 89 --------------------------------------------------------------- which looks reasonable (ENMFILE, `No more files', is it?) to me. I don't see anything from `NtQueryDirectoryFile' until the report above. So, the upshot appears to be that `FileIDBothDirectoryInformation' doesn't work at all, `FileBothDirectoryInformation' works, and `FileDirectoryInformation' is somewhere in between, but not in a useful way. Is that what you wanted to discover, or did I miss the point? In user-operations terms, I now seem to have a situation I can deal with, in that I have a latest-release version of `cygwin1.dll' that local users can work with, and for the moment at least I have the means to tweak and build any subsequent releases. If at some point what's been discovered could make it into the real release, I would be most grateful. -- SAm. -- Academic Excellence at the Heart of Scotland.
