Dragging shortcut onto emulation window

mark_k · 05 February 2013, 21:32

I just — accidentally as it happens — dragged a shortcut icon from the Windows desktop and dropped it on the emulation window. WinUAE automatically mounted the file. Unfortunately shortcut .lnk files aren't much use on the Amiga side. Would it be possible to mount the file which the shortcut points to instead in that case?

Toni Wilen · 12 February 2013, 16:47

Done.

Does this cover shortcuts (.lnk) to real folders and real folders too? Thanks

mark_k · 16 February 2013, 17:59

I just checked and dropping a shortcut to a folder or the folder itself both work fine, the folder is mounted on the Amiga side.

I am also trying to support shortcuts in directory filesystems as AmigaOS soft links but it may not be that easy because AOS softlink support is a bit weird.

Toni Wilen · 24 February 2013, 12:38

Shortcuts as softlinks done now, at least they appear to work, even shortcuts across volumes if target volume is also mounted as a directory drive.

Question: should softlinks appear on Amiga side with or without .lnk extension?

EDIT: real soft links will be also supported.

I did some brief testing in Windows Vista with a couple of shared folders on the NTFS boot partition. I put a shortcut to the first shared folder in the second shared folder.

Booting Workbench 3.1, CDing to the second shared folder and doing Dir ALL gives an error message: Error, circular directory found
CDing to the shortcut leaves the current dir at the second shared folder.

Booting Workbench 1.3 (still with Kickstart 3.1) and doing the same, this time running Dir from the Workbench 1.3 C directory, prints several nested directories before exiting.

Booting Workbench 1.3 with Kickstart 1.3, doing Dir ALL reports: Could not get information for "WinUAE shared - Shortcut.lnk" - Error 233

So for some reason the emulated machine thinks the soft link to the first shared folder is actually a (recursive) link to the second shared folder.

And Kickstart 1.3 can't handle soft links. Maybe best to disable them under 1.3? Or you could implement them transparently, so for a shortcut to a directory, present that as a normal subdirectory. Probably no point in trying to do that though.

As for shortcut names. It might be best to remove the .lnk since it would shorten file/dir names on the Amiga side. On the other hand, having the .lnk extension would tell the user that the file is a shortcut/softlink.

Toni Wilen · 26 February 2013, 20:38

I think you should do some testing with more basic commands than dir all. (like if dir <shortcut.lnk/some/path> or type <shortcut.lnk>/somefile.txt> work and so on). Dir all won't really explain what goes wrong.

I already decided to not to remove .lnk, it separates between shortcuts and real host-side soft links.

Does 1.3 really need special handling? IMHO they were useless previously and still are useless under 1.3.

Only if you want to spend lots of time implementing a feature which probably no-one is going to use.

Useful or not, feature will be implemented if I want to implement it and I wanted to implement this one

The problem seems to be that each shortcut in shared folder #1, whether it's to shared folder #2, or to a folder inside shared folder #2, is being treated as a link to shared folder #1. Hence the circular directory found message.

I ran WinUAE with -log but there didn't seem to be any diagnostic/log output related to shortcuts/links. The config I used and some log output are attached.

Maybe worth noting: I had a third shared folder defined in the config, to D:\. But the D: drive was not present when I did the tests.

Oops, when both source and target are in same host drive, it selects first virtual drive that points to this host drive..

I only tested if source and target are in different host drives

Toni Wilen · 27 February 2013, 15:53

What kind of directory configuration do you have? Do you have same directory tree partially mounted twice? (for example "d:\blah\blah2" and "d:\blah\blah2\blah3" -> blah3 contents are visible in both "drives")

mark_k · 27 February 2013, 16:15

I made two folders on the Windows desktop, "WinUAE shared" and "WinUAE shared 2". Those were defined as shared on the Amiga side as SHARE: (volume name Shared) and SHARE2: (volume name Shared 2).

I created a shortcut to the "WinUAE shared" folder and put it in the "WinUAE shared 2" folder. I also created a shortcut to a folder inside "WinUAE shared", and put that in the "WinUAE shared 2" folder too.

Toni Wilen · 27 February 2013, 16:44

I am not sure if I understood what you meant but winuae.zip updated, some updates + logging added

mark_k · 27 February 2013, 18:45

Here's the log output for trying to CD to a .lnk then do a Dir ALL on it. It seems Windows is returning the short name version of shortcut destinations? (What would happen if the user has disabled short name creation on their NTFS partition?)

Toni Wilen · 27 February 2013, 19:45

Apparently path can contain long or short names or both.. Updated, should work now.

mark_k · 27 February 2013, 22:14

Yes, it seems to work okay now.

I tried using the MakeLink command in the hope that would create a shortcut in the shared folder, but instead got this log output:
FILESYS: UNSUPPORTED PACKET 3fd

I also tried making a shortcut to a file. The Dir command shows that as a directory in the listing. And (the shortcut was to a .lzh archive) doing lha vv [shortcutname], LhA reported
LhA: Unable to open archive file 'imploder-4.0.lzh'

I don't know whether LhA does that with soft links on an FFS volume or not. The log output on doing that was

Code:

46-434 [31361 223=133]: got target 'Shared:imploder-4.0.lzh'

Toni, would you have an .ADF image you could upload featuring at least one AmigaDOS soft link and preferably at least one hard link too?

I'm sorry to post this request here. I have been reading The .ADF (Amiga Disk File) FAQ, but the way links are implemented in AmigaDOS is still an area of mystery to me and it would be useful to see one or two examples.

Thanks.

If you drag & drop a shortcut to an already-mounted shared folder on the emulation window, WinUAE mounts the folder again. Except this time there's an issue with short filenames; in my case it was mounted as WINUAE~1:

Code:

09-254 [4631 000=105]: filesys_insert(-1,'<?>','C:\Users\Mark\Desktop\WINUAE~1','0','0)
09-256 [4631 000=105]: filesys_insert 1 done!
09-291 [4631 007=108]: FILESYS: inserted volume NR=1 RO=0 'WINUAE~1' ('C:\Users\Mark\Desktop\WINUAE~1')

Also, it may be a good idea to not make the .lnk suffix visible on the Amiga side. If on the Amiga side you rename the soft link/shortcut so it doesn't end in .lnk, WinUAE renames the .lnk file on the Windows side, which turns it into a regular file that Windows no longer recognises as a shortcut.
