           Summary: std.file uses unconventional file permissions
           Product: D
           Version: 2.035
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bugzilla kyllingen.net

The Posix version of std.file.write() creates files with the permission 0660. I
think most users will expect it to be the conventional 0666, which is the
default for the C fopen() function.

std.file.copy() also uses 0660, whereas the Posix cp command preserves the
permissions of the source file (as well as ownership and timestamps).

The security aspect should be taken care of by the process' umask, which in the
vast majority of cases will be 0022. (The resulting file will then have
permissions 0644.)

I just grepped through all of Phobos for "0660", and I see that the std.mmfile
module also uses these permissions. I'm not sure whether this should be
changed, though, because I haven't really used memory-mapped files and don't
know how they are used. Just thought I should mention it.
