It is not required. What _is_ required is that the path to the current executable is mapped, somewhere.

We've been through this before. Wine is not Windows. In Wine, the drive has to be mapped in dosdevices.

But you're NOT running the test from a network drive, are you? And even if you were, you'd need some way to inform Wine that it's there, which would be to map it to a drive. Does Wine even support Windows-style shares?

You should probably verify this.

And you are looking at the wrong bug... 1 The bug in question is actually : 18283 (now closed as the issue was resolved by the mapping) not 17996.
18283 didn't come up in my search. It would have been much easier if you mentioned the bug number when you first mentioned that you reported a bug for this.
The only way to fix it was mapping the / drive or mapping the ~/wine-git directory to a physical drive for wine to use...
Yes. This is how it works. This is how it always has worked.
In Windows you don't nescissarily need to map a drive to run an application from that networked drive.
It's NOT a networked drive, is it? Drive mappings are the only way to tell Wine and apps running in Wine where your files are in your host-system (Unix-style) filesystem.
Note that it would be a breach of security to allow some method to access / without a direct mapping in dosdevices.
Also no its not a PEBKAC it is a valid question and a request for comment not a request for insult and slam.
This message appears in your bug report:
Warning: could not find DOS drive for current working directory '/home/cahrendt/wine-git/dlls/inetmib1/tests', starting in the Windows directory.
PEBKAC QED.
Grow up..
How about you *THINK* about what you're doing and how it works before reporting obviously invalid bugs?

The important part here is that your local drives are local drives. Don't confuse the Wine drive mappings with network drive mappings in Windows. Think about a Wine drive mapping like plugging a new hdd into your box.
But you're NOT running the test from a network drive, are you? And even if you were, you'd need some way to inform Wine that it's there, which would be to map it to a drive. Does Wine even support Windows-style shares?
Nope. We could, but then you'd have to create a Samba share to allow us to use the directory. I'm pretty sure a wine drive mapping is easier and faster.
Also from a command line I can do (I think if I am remembering correctly (been doing to much z work lately) ) //server/directory/app.exe and it will retrieve and run the app... (I think)
That's a bit besides the point, as this is still a valid UNC path. Now imagine I've got a USB hdd with my app on it, and that's usually connected at U:, with my app being at U:\test\app.exe. Now the logic in Windows mapping my USB drive to U: is just what the wine dosdevice mapping is like. If I now tell windows to remove the USB device, my desktop link to U:\test\app.exe is not going to work anymore.
This message appears in your bug report:
Warning: could not find DOS drive for current working directory '/home/cahrendt/wine-git/dlls/inetmib1/tests', starting in the Windows directory.
Here my analogy would be a bit stretched, as in that you'd still manage to be on the USB drive while it's already been disconnected. But basically you're trying to run a program that's on a drive not connected to your wine "box".
Cheers, Kai

The discussion on wine-devel in April related to bug 15883 suggested the implementation of \?\unix\ which would in turn allow programs access to things that aren't mapped in the DosDevices list, unless specifically disallowed (which wasn't discussed at the time)
A quick look at [1] suggests that \?\unix\etc/hostname would seem to be a reasonable thing to expect to work under Wine.

How so? I'm fairly sure this suggestion was dismissed in the above-mentioned email discussions as well.

But that requires either 1) the app to be aware of \?\unix, or 2) Wine to map \?\unix/foo/bar when no drive mapping to /foo/bar exists.
#2 would also require some way to be configured to allow the equivalent of removing the default Z: drive mapping for people who want it. However, it would not provide any additional functionality and could easily be considered a waste of time. Of course, that's not up to me ;)

AFAIK, the main reason people remove the Z: mapping is a security concern. It's not an issue for me, but some people like to restrict the files that win32 apps can access to a subdirectory in $HOME. If there's some workaround to access files outside the drive mapping (assuming pure win32 of course :D ), then unless it can be disabled by the user, it's a security breach.

But that requires either
- the app to be aware of \?\unix, or
This would be rather badly broken. The point of \?\ is that apps (and in fact the Win32 API) doesn't parse such paths, but passes them on to the filesystem.
- Wine to map \?\unix/foo/bar when no drive mapping to /foo/bar exists.
The _point_ is that if Wine sees a \?\unix/foo/bar path, it operates upon the file at /foo/bar, irrespective of the drive mappings.
#2 would also require some way to be configured to allow the equivalent of removing the default Z: drive mapping for people who want it. However, it would not provide any additional functionality and could easily be considered a waste of time. Of course, that's not up to me ;)
The point of \?\unix is not to add functionality, it's to allow removal of current functionality, specifically the magic recognition of "/x/y" as a unix path instead of "X:/x/y" with X as the drive of the current working directory, in order to fix bug 15883.
Note that it would be a breach of security to allow some method to access / without a direct mapping in dosdevices.

The point made as I recall it in the earlier thread is that this is a false sense of security, and that apps can already get outside the drive mappings for filesystem access.
I don't know how, but that was the point that was made.
Off the top of my head, there's Win32 APIs that let you enumerate and map physical disk devices to DOS drive letters. So you could just readd Z:\ in your app if you wanted.
Frankly I would like to break that illusion of security by providing \?\unix, if I find the time. (The hard part is identifying all the parts of Wine that use the '/' recognition to function)

Linux syscalls. A Windows app can happily call int 0x80 to do whatever a Linux app running with the same permissions can do. It requires the app to be aware of Wine though.
