[Bug 22450] New: Can't disable unixfs
http://bugs.winehq.org/show_bug.cgi?id=22450 Summary: Can't disable unixfs Product: Wine Version: 1.1.43 Platform: x86 OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: shell32 AssignedTo: wine-bugs(a)winehq.org ReportedBy: dank(a)kegel.com dlls/shell32/shfldr_unixfs.c claims that you can disable unixfs by deleting the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\Namespace\{9D20AAE8-0625-44B0-9CA7-71889C2254D9} but unfortunately wine will recreate that key the next time you run a newer version of Wine. To repeat, do rm -rf ~/.wine wine regedit /d 'HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\Namespace\{9D20AAE8-0625-44B0-9CA7-71889C2254D9}' wine notepad # Do File/Open and note that / does not appear in My Computer. wineserver -w ~/wine-git/wine notepad # Do File/Open and note that / *does* appear. If we really want to disable unixfs, we may want a configure option to not even compile it in. I have a patch ready, will send it in. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I strongly suggest incorporating this patch, and also documenting the existence of unixfs in the same place as the drive mappings so people are not misled. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
http://bugs.winehq.org/show_bug.cgi?id=22450 --- Comment #3 from Andrew Church <achurch+wine(a)achurch.org> 2013-08-10 12:25:19 CDT --- Created attachment 45572 --> http://bugs.winehq.org/attachment.cgi?id=45572 Patch against wine-1.7.0 This patch extends Dan Kegel's patch (which applies more or less cleanly against 1.7.0) to also disable code in ntdll which generates unixfs pathnames. I've tested this with a few random programs and it seems to work (modulo the wineboot issue below). The only two remaining uses of unixfs I can see are: - krnl386.exe16 (int21.c and vxd.c): Something to do with magic device names. I don't know what the code is supposed to do, so I can't suggest how to fix it. - wineboot: This attempts to apply wine.inf from the global Wine data directory (e.g. /usr/share/wine). If I hack wineboot.c to use "z:" instead of "\\?\unix" and restore the z: -> / link, it works as expected, but of course this breaks the whole idea of avoiding full host filesystem access. I think this may need to change to have the "wine" binary itself copy the data files into a Windows-API-visible temporary directory (c:\windows\temp or whatever) before wineboot is executed. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
