[Bug 15679] New: cygwin symlinks not working in wine

Summary: cygwin symlinks not working in wine Product: Wine Version: 1.1.6 Platform: Other URL: http://cygwin.com OS/Version: other Status: NEW Keywords: download, source Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: dank@kegel.com

Surprisingly, cygwin seems to work nowadays, as long as you do everything inside a wineconsole running cygwin.bat. (Perhaps cygwin apps should work outside wineconsole; that would be a separate bug report.)

However, cygwin's gcc doesn't work unless you replace certain cygwin symlinks with unix ones, e.g. $ cd .wine/drive_c/cygwin/usr/i686-pc-cygwin/bin $ for a in *; do ln -sf ../../../bin/$a; done

Likewise, /bin/vi doesn't work, as it's a symlink to vim.exe.

In fact, cygwin's ls -l doesn't even recognize cygwin's symlinks as such:

$ ls -l vi -rw-r--r-- 1 dank mkpasswd 18 Oct 19 05:53 vi $ cat vi !<symlink>vim.exe

So either they're not being created right, or they're not being recognized properly by cygwin for some reason, or both.

--- Comment #1 from Paul "TBBle" Hampson Paul.Hampson@Pobox.com 2009-01-13 06:01:05 --- To recognise that kind of shortcut (which the Cygwin source refers to as old-style shortcuts, contrasted with enhanced .lnk files) the file needs to have the System attribute set, and not the Directory attribute.

I presume the problem is that Wine doesn't show files as marked with the System attribute, since there's no really useful POSIX equivalent that comes to mind, so it prolly ignores the cygwin request to mark the file with the System attribute.

I haven't looked at the Wine code to verify this.

There's a winsymlinks option in the CYGWIN environment variable or the registry which enables .lnk-based symlinks, but those are only processed if marked Read-Only and non-Directory.

--- Comment #5 from Dan Kegel dank@kegel.com 2009-08-27 23:47:03 --- Or maybe cygwin could always use .lnk symlinks on wine.

Looking at path.cc, I see there is already a special case for one odd filesystem that doesn't support the system attribute:

/* MVFS doesn't handle the SYSTEM DOS attribute, but it handles the R/O attribute. Therefore we create symlinks on MVFS always as shortcuts. */ mk_winsym |= win32_newpath.fs_is_mvfs ();

How 'bout extending that special case to handle wine, too, a la

/* MVFS doesn't handle the SYSTEM DOS attribute, but it handles the R/O attribute. Therefore we create symlinks on MVFS always as shortcuts. Same thing for Wine... it lies about its filesystem, so just detect Wine in general. */ mk_winsym |= win32_newpath.fs_is_mvfs () || is_wine ();

where is_wine() is something like

bool is_wine() { static bool iswine = false; static bool checked = false; if (!checked) { HMODULE h = GetModuleHandle("ntdll.dll"); if (h && GetProcAddress(hntdll, "wine_get_version")) iswine = true; checked = true; } return iswine; }

? Or is that too gross?

(BTW I tried exporting CYGWIN=winsymlinks before running cygwin's setup when installing from scratch, but it didn't see to work; I would have expected /bin/cc to be installed when I selected the 'gcc' package, but it wasn't, nor were there any .lnk files in /bin.)

Now that Ubuntu and Fedora turn on user_xattr by default, maybe we can use xattr's to store the hidden and system bits.

So implementing partial support for FILE_ATTRIBUTE_SYSTEM using xattr wasn't too hard. The attached patch passes its tests on vista and wine. It should compile on mac. For info about porting it to bsd and solaris, see the (unapplied) patch to apr, http://oss.metaparadigm.com/apache-privsep/2.3.0-dev/xattr-patches/apr-xattr...

BUT it doesn't seem to make cygwin recognize /usr/bin/vi as a real symlink, so there may be more to do.

This draft makes FindNextFile see the system attribute, too. It still doesn't make cygwin's ls happy. And it doesn't validate the contents of the xattr properly yet. Time for more conformance tests.

Hey, this version seems to work. ('Course, you need either or both of the patches to fix wineconsole and cygwin crashes to be able to tell that cygwin symlinks are recognized.) It's less ugly but a bit more invasive.

Includes tests; they pass on both Wine and Vista.

Next step is to handle the HIDDEN attribute as well, and make sure it doesn't cause any regressions.

This one adds support for setting attributes in cmd's attrib verb. Seems to be in good shape on linux. Next step is to get it working on mac, and do full conformance and appinstall tests.

This draft addresses feedback from Alexandre Julliard. It adds tests for directories and symlinks to directories. Needs to be split up into about five pieces. Only tested on Ubuntu 8.04 which lacks xattr support; tests pass on Windows Vista.

Could someone retest this? I believe this should be fixed (for most platforms) by commit 0a223f17e1fb4aafb43906aeffe00eadc81cf8c2.

In cygwin bash: $ mkdir a $ ln -s a b $ ls -lisahd a b 172527619 0 drwx---r-x+ 1 RECHNER+bernhard ... 0 18. Okt 22:13 a 172504287 4,0K lrwxrwxrwx 1 RECHNER+bernhard ... 1 18. Okt 22:13 b -> a

In wine64 cmd: C:>dir b File not found.

C:>attrib b AS C:\b

In native bash: $ hexdump -C b 00000000 21 3c 73 79 6d 6c 69 6e 6b 3e ff fe 61 00 00 00 |!<symlink>..a...| 00000010

(tested with a few unrelated patches applied to get cygwin running.)

From my point of view cygwin recognizes now the symlinks correctly. I guess this bug could be closed then.
