  22  * As you know, windows and unix do have a different philosophy with regard to
  23  * the question of how a filesystem should be laid out. While we unix geeks
  24  * learned to love the 'one-tree-rooted-at-/' approach, windows has in fact
  25  * a whole forest of filesystem trees, each of which is typically identified by
  26  * a drive letter.
  27  *
  28  * We would like wine to integrate as smoothly as possible (that is without
  29  * sacrificing win32 compatibility) into the unix environment. For the
  30  * filesystem question, this means we really would like those windows
  31  * applications to work with unix path- and file-names. Unfortunately, this
  32  * seems to be impossible in general. Therefore we have those symbolic links
  33  * in wine's 'dosdevices' directory, which are used to simulate drives
  34  * to keep windows applications happy. And as a consequence, we have those
  35  * drive letters show up now and then in GUI applications running under wine,
  36  * which gets the unix hardcore fans all angry, shouting at us @#!&$%* wine
  37  * hackers that we are seducing the big companies not to port their applications
  38  * to unix.
  39  *
  40  * DOS paths do appear at various places in GUI applications. Sometimes, they
  41  * show up in the title bar of an application's window. They tend to accumulate
  42  * in the most-recently-used section of the file-menu. And I've even seen some
  43  * in a configuration dialog's edit control. In those examples, wine can't do a
  44  * lot about this, since path-names can't be told appart from ordinary strings
  45  * here. That's different in the file dialogs, though.
  46  *
  47  * With the introduction of the 'shell' in win32, Microsoft established an
  48  * abstraction layer on top of the filesystem, called the shell namespace (I was
  49  * told that Gnome's virtual filesystem is conceptually similar). In the shell
  50  * namespace, one doesn't use ascii- or unicode-strings to uniquely identify
  51  * objects. Instead Microsoft introduced item-identifier-lists (The c type is
  52  * called ITEMIDLIST) as an abstraction of path-names. As you probably would
  53  * have guessed, an item-identifier-list is a list of item-identifiers (whose
  54  * c type's funny name is SHITEMID), which are opaque binary objects. This means
  55  * that no application (apart from Microsoft Office) should make any assumptions
  56  * on the internal structure of these SHITEMIDs.
  57  *
  58  * Since the user prefers to be presented the good-old DOS file-names instead of
  59  * binary ITEMIDLISTs, a translation method between string-based file-names and
  60  * ITEMIDLISTs was established. At the core of this are the COM-Interface
  61  * IShellFolder and especially it's methods ParseDisplayName and
  62  * GetDisplayNameOf. Basically, you give a DOS-path (let's say C:\windows) to
  63  * ParseDisplayName and get a SHITEMID similar to <Desktop|My Computer|C:|windows|>.
  64  * Since it's opaque, you can't see the 'C', the 'windows' and the other stuff.
  65  * You can only figure out that the ITEMIDLIST is composed of four SHITEMIDS.
  66  * The file dialog applies IShellFolder's BindToObject method to bind to each of
  67  * those four objects (Desktop, My Computer, C: and windows. All of them have to
  68  * implement the IShellFolder interface.) and asks them how they would like to be
  69  * displayed (basically their icon and the string displayed). If the file dialog
  70  * asks <Desktop|My Computer|C:|windows> which sub-objects it contains (via
  71  * EnumObjects) it gets a list of opaque SHITEMIDs, which can be concatenated to
  72  * <Desktop|...|windows> to build a new ITEMIDLIST and browse, for instance,
  73  * into <system32>. This means the file dialog browses the shell namespace by
  74  * identifying objects via ITEMIDLISTs. Once the user has selected a location to
  75  * save his valuable file, the file dialog calls IShellFolder's GetDisplayNameOf
  76  * method to translate the ITEMIDLIST back to a DOS filename.
  77  *
  78  * It seems that one intention of the shell namespace concept was to make it
  79  * possible to have objects in the namespace, which don't have any counterpart
  80  * in the filesystem. The 'My Computer' shell folder object is one instance
  81  * which comes to mind (Go try to save a file into 'My Computer' on windows.)
  82  * So, to make matters a little more complex, before the file dialog asks a
  83  * shell namespace object for it's DOS path, it asks if it actually has one.
  84  * This is done via the IShellFolder::GetAttributesOf method, which sets the
  85  * SFGAO_FILESYSTEM if - and only if - it has.
  86  *
  87  * The two things, described in the previous two paragraphs, are what unixfs is
  88  * based on. So basically, if UnixDosFolder's ParseDisplayName method is called
  89  * with a 'c:\windows' path-name, it doesn't return an
  90  * <Desktop|My Computer|C:|windows|> ITEMIDLIST. Instead, it uses
  91  * shell32's wine_get_unix_path_name and the _posix_ (which means not the win32)
  92  * fileio api's to figure out that c: is mapped to - let's say -
  93  * /home/mjung/.wine/drive_c and then constructs a
  94  * <Desktop|/|home|mjung|.wine|drive_c> ITEMIDLIST. Which is what the file
  95  * dialog uses to display the folder and file objects, which is why you see a
  96  * unix path. When the user has found a nice place for his file and hits the
  97  * save button, the ITEMIDLIST of the selected folder object is passed to
  98  * GetDisplayNameOf, which returns a _DOS_ path name
  99  * (like H:\home_of_my_new_file out of <|Desktop|/|home|mjung|home_of_my_new_file|>).
 100  * Unixfs basically mounts your dos devices together in order to construct
 101  * a copy of your unix filesystem structure.
 102  *
 103  * But what if none of the symbolic links in 'dosdevices' points to '/', you
 104  * might ask ("And I don't want wine have access to my complete hard drive, you
 105  * *%&1#!"). No problem, as I stated above, unixfs uses the _posix_ apis to
 106  * construct the ITEMIDLISTs. Folders, which aren't accessible via a drive letter,
 107  * don't have the SFGAO_FILESYSTEM flag set. So the file dialogs should'nt allow
 108  * the user to select such a folder for file storage (And if it does anyhow, it
 109  * will not be able to return a valid path, since there is none). Think of those
 110  * folders as a hierarchy of 'My Computer'-like folders, which happen to be a
 111  * shadow of your unix filesystem tree. And since all of this stuff doesn't
 112  * change anything at all in wine's fileio api's, windows applications will have
 113  * no more access rights as they had before.
 114  *
 115  * To sum it all up, you can still savely run wine with you root account (Just
 116  * kidding, don't do it.)
 117  *
 118  * If you are now standing in front of your computer, shouting hotly
 119  * "I am not convinced, Mr. Rumsfeld^H^H^H^H^H^H^H^H^H^H^H^H", fire up regedit
 120  * and delete HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
 121  * Explorer\Desktop\Namespace\{9D20AAE8-0625-44B0-9CA7-71889C2254D9} and you
 122  * will be back in the pre-unixfs days.
