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.
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.
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 apart from ordinary strings
45 * here. That's different in the file dialogs, though.
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.
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.
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.
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.
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 shouldn't 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.
115 * To sum it all up, you can still safely run wine with you root account (Just
116 * kidding, don't do it.)
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.
