While we unix geeks * learned to love the 'one-tree-rooted-at-/' approach, windows has in fact * a whole forest of filesystem trees, each of which is typically identified by * a drive letter. * * We would like wine to integrate as smoothly as possible (that is without * sacrificing win32 compatibility) into the unix environment. For the * filesystem question, this means we really would like those windows * applications to work with unix path- and file-names. Unfortunately, this * seems to be impossible in general. Therefore we have those symbolic links * in wine's 'dosdevices' directory, which are used to simulate drives * to keep windows applications happy. And as a consequence, we have those * drive letters show up now and then in GUI applications running under wine, * which gets the unix hardcore fans all angry, shouting at us @#!&$%* wine * hackers that we are seducing the big companies not to port their applications * to unix. * * DOS paths do appear at various places in GUI applications. Sometimes, they * show up in the title bar of an application's window. They tend to accumulate * in the most-recently-used section of the file-menu. And I've even seen some * in a configuration dialog's edit control. In those examples, wine can't do a * lot about this, since path-names can't be told appart from ordinary strings * here. That's different in the file dialogs, though. * * With the introduction of the 'shell' in win32, Microsoft established an * abstraction layer on top of the filesystem, called the shell namespace (I was * told that Gnome's virtual filesystem is conceptually similar). In the shell * namespace, one doesn't use ascii- or unicode-strings to uniquely identify * objects. Instead Microsoft introduced item-identifier-lists (The c type is * called ITEMIDLIST) as an abstraction of path-names. As you probably would * have guessed, an item-identifier-list is a list of item-identifiers (whose * c type's funny name is SHITEMID), which are opaque binary objects. This means * that no application (apart from Microsoft Office) should make any assumptions * on the internal structure of these SHITEMIDs. * * Since the user prefers to be presented the good-old DOS file-names instead of * binary ITEMIDLISTs, a translation method between string-based file-names and * ITEMIDLISTs was established. At the core of this are the COM-Interface * IShellFolder and especially it's methods ParseDisplayName and * GetDisplayNameOf. Basically, you give a DOS-path (let's say C:\windows) to * ParseDisplayName and get a SHITEMID similar to <Desktop|My Computer|C:|windows|>. * Since it's opaque, you can't see the 'C', the 'windows' and the other stuff. * You can only figure out that the ITEMIDLIST is composed of four SHITEMIDS. * The file dialog applies IShellFolder's BindToObject method to bind to each of * those four objects (Desktop, My Computer, C: and windows. All of them have to * implement the IShellFolder interface.) and asks them how they would like to be * displayed (basically their icon and the string displayed). If the file dialog * asks <Desktop|My Computer|C:|windows> which sub-objects it contains (via * EnumObjects) it gets a list of opaque SHITEMIDs, which can be concatenated to * <Desktop|...|windows> to build a new ITEMIDLIST and browse, for instance, * into <system32>. This means the file dialog browses the shell namespace by * identifying objects via ITEMIDLISTs. Once the user has selected a location to * save his valuable file, the file dialog calls IShellFolder's GetDisplayNameOf * method to translate the ITEMIDLIST back to a DOS filename. * * It seems that one intention of the shell namespace concept was to make it * possible to have objects in the namespace, which don't have any counterpart * in the filesystem. The 'My Computer' shell folder object is one instance * which comes to mind (Go try to save a file into 'My Computer' on windows.) * So, to make matters a little more complex, before the file dialog asks a * shell namespace object for it's DOS path, it asks if it actually has one. * This is done via the IShellFolder::GetAttributesOf method, which sets the * SFGAO_FILESYSTEM if - and only if - it has. * * The two things, described in the previous two paragraphs, are what unixfs is * based on. So basically, if UnixDosFolder's ParseDisplayName method is called * with a 'c:\windows' path-name, it doesn't return an * <Desktop|My Computer|C:|windows|> ITEMIDLIST. Instead, it uses * shell32's wine_get_unix_path_name and the _posix_ (which means not the win32) * fileio api's to figure out that c: is mapped to - let's say - * /home/mjung/.wine/drive_c and then constructs a * <Desktop|/|home|mjung|.wine|drive_c> ITEMIDLIST. Which is what the file * dialog uses to display the folder and file objects, which is why you see a * unix path. When the user has found a nice place for his file and hits the * save button, the ITEMIDLIST of the selected folder object is passed to * GetDisplayNameOf, which returns a _DOS_ path name * (like H:\home_of_my_new_file out of <|Desktop|/|home|mjung|home_of_my_new_file|>). * Unixfs basically mounts your dos devices together in order to construct * a copy of your unix filesystem structure. * * But what if none of the symbolic links in 'dosdevices' points to '/', you * might ask ("And I don't want wine have access to my complete hard drive, you * *%&1#!"). No problem, as I stated above, unixfs uses the _posix_ apis to * construct the ITEMIDLISTs. Folders, which aren't accessible via a drive letter, * don't have the SFGAO_FILESYSTEM flag set. So the file dialogs should'nt allow * the user to select such a folder for file storage (And if it does anyhow, it * will not be able to return a valid path, since there is none). Think of those * folders as a hierarchy of 'My Computer'-like folders, which happen to be a * shadow of your unix filesystem tree. And since all of this stuff doesn't * change anything at all in wine's fileio api's, windows applications will have * no more access rights as they had before. * * To sum it all up, you can still savely run wine with you root account (Just * kidding, don't do it.) * * If you are now standing in front of your computer, shouting hotly * "I am not convinced, Mr. Rumsfeld^H^H^H^H^H^H^H^H^H^H^H^H", fire up regedit * and delete HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ * Explorer\Desktop\Namespace\{9D20AAE8-0625-44B0-9CA7-71889C2254D9} and you * will be back in the pre-unixfs days. */ #include "config.h" #include "wine/port.h" #include <stdio.h> #include <stdarg.h> #include <limits.h> #include <dirent.h> #include <stdlib.h> #ifdef HAVE_UNISTD_H # include <unistd.h> #endif #ifdef HAVE_SYS_STAT_H # include <sys/stat.h> #endif #ifdef HAVE_PWD_H # include <pwd.h> #endif #include <grp.h> #include <limits.h> #define COBJMACROS #define NONAMELESSUNION #define NONAMELESSSTRUCT #include "windef.h" #include "winbase.h" #include "winuser.h" #include "objbase.h" #include "winreg.h" #include "shlwapi.h" #include "winternl.h" #include "wine/debug.h" #include "shell32_main.h" #include "shellfolder.h" #include "shfldr.h" #include "shresdef.h" #include "pidl.h" WINE_DEFAULT_DEBUG_CHANNEL(shell); #define ADJUST_THIS(c,m,p) ((c*)(((long)p)-(long)&(((c*)0)->lp##m##Vtbl))) #define STATIC_CAST(i,p) ((i*)&p->lp##i##Vtbl) #define LEN_SHITEMID_FIXED_PART ((USHORT) \ ( sizeof(USHORT) /* SHITEMID's cb field. */ \ + sizeof(PIDLTYPE) /* PIDLDATA's type field. */ \ + sizeof(FileStruct) /* Well, the FileStruct. */ \ - sizeof(char) /* One char too much in FileStruct. */ \ + sizeof(FileStructW) /* You name it. */ \ - sizeof(WCHAR) /* One WCHAR too much in FileStructW. */ \ + sizeof(WORD) )) /* Offset of FileStructW field in PIDL. */ #define PATHMODE_UNIX 0 #define PATHMODE_DOS 1 /* UnixFolder object layout and typedef. */ typedef struct _UnixFolder { const IShellFolder2Vtbl *lpIShellFolder2Vtbl; const IPersistFolder3Vtbl *lpIPersistFolder3Vtbl; const IPersistPropertyBagVtbl *lpIPersistPropertyBagVtbl; const IDropTargetVtbl *lpIDropTargetVtbl; const ISFHelperVtbl *lpISFHelperVtbl; LONG m_cRef; CHAR *m_pszPath; /* Target path of the shell folder (CP_UNIXCP) */ LPITEMIDLIST m_pidlLocation; /* Location in the shell namespace */ DWORD m_dwPathMode; DWORD m_dwAttributes; const CLSID *m_pCLSID; DWORD m_dwDropEffectsMask; } UnixFolder; /* Will hold the registered clipboard format identifier for ITEMIDLISTS. */ static UINT cfShellIDList = 0; /****************************************************************************** * UNIXFS_is_rooted_at_desktop [Internal] * * Checks if the unixfs namespace extension is rooted at desktop level. * * RETURNS * TRUE, if unixfs is rooted at desktop level * FALSE, if not. */ BOOL UNIXFS_is_rooted_at_desktop(void) { HKEY hKey; WCHAR wszRootedAtDesktop[69 + CHARS_IN_GUID] = { 'S','o','f','t','w','a','r','e','\\','M','i','c','r','o','s','o','f','t','\\', 'W','i','n','d','o','w','s','\\','C','u','r','r','e','n','t','V','e','r','s','i','o','n','\\', 'E','x','p','l','o','r','e','r','\\','D','e','s','k','t','o','p','\\', 'N','a','m','e','S','p','a','c','e','\\',0 }; if (StringFromGUID2(&CLSID_UnixDosFolder, wszRootedAtDesktop + 69, CHARS_IN_GUID) && RegOpenKeyExW(HKEY_LOCAL_MACHINE, wszRootedAtDesktop, 0, KEY_READ, &hKey) == ERROR_SUCCESS) { RegCloseKey(hKey); return TRUE; } return FALSE; } /****************************************************************************** * UNIXFS_filename_from_shitemid [Internal] * * Get CP_UNIXCP encoded filename corresponding to the first item of a pidl * * PARAMS * pidl [I] A simple SHITEMID * pszPathElement [O] Filename in CP_UNIXCP encoding will be stored here * * RETURNS * Success: Number of bytes necessary to store the CP_UNIXCP encoded filename * _without_ the terminating NUL. * Failure: 0 * * NOTES * Size of the buffer at pszPathElement has to be FILENAME_MAX. pszPathElement * may be NULL, if you are only interested in the return value. */ static int UNIXFS_filename_from_shitemid(LPCITEMIDLIST pidl, char* pszPathElement) { FileStructW *pFileStructW = _ILGetFileStructW(pidl); int cLen = 0; if (pFileStructW) { cLen = WideCharToMultiByte(CP_UNIXCP, 0, pFileStructW->wszName, -1, pszPathElement, pszPathElement ?
