Subject: [bug] FileList drag-and-drop does not work between file systems in 3.9
Date: 11. April 2006 17:57:31 GMT+02:00
Since the earliest days of Squeak, the FileList has been a great utility to fall back on, either when nothing else works, or when you don't have other software to do the job. Until recently, it was possible to browse to *any* file on any directory *or server*, copy there, browse to another directory, make a file, paste and save. It was consistent and it worked.
Now if you do this with a binary file, as others have observed, the thing that gets stored bears almost no resemblance to the original file, even though the UI actions boil down to copy-paste.
I was going to complain about this (I have been using an old Squeak for a long time for just this reason) except that, using drag-and-drop, the right thing happens, and it's actually easier to do...
...but only in *some cases*. What is needed is a little work on file drag-and-drop for the case of copying between different devices or servers (ie between separate file systems). Specifically the following three fixes would, I believe, restore proper operation in this case...
1. Recognize this case from the fact that the two directories do not have a common root.
2. Convert simple drags from 'move' to 'copy' in this case, and
3. Do the right thing with file names and directories. Naturally the destination name
should be the local name of the source plus the path name of the target directory.
The fact that the FileList can do FTP between servers makes it a very powerful tool if other things are working right. I apologize for not having time to do this myself right now, but I think it would be a noble service for our shiny new Squeak 3.9 if file drag-and-drop could be made to work properly in the FileList.
PS: To anyone working on this, you will notice considerable delays when switching windows open on different servers, and it helps to have a Transcript open to understand what is going on. It would probably be nice to figure how to reduce these delays or put up a little informer so that normal users will understand that things are happening behind the scene. I think the best solution would be to make re-opening the connection a lazy operation, rather than eagerly on window wake-up, but we shouldn't let that get in the way of the relatively simple fixes above.
