[fuse-devel] Virtual folder disappears after mkdir in GUI save dialog
|

Hi,
As some might know by my previous post "Rmdir via GUI = recursive
through virtual folders", I'm working on a combination of a
hierarchical and tag-based filesystem and I'm running into another
problem.
When you want to save a file from within an application, you browse
through the hierarchy to select the folder to save it in. It is
possible to immediately add tags to the file by browsing deeper into a
+ADD folder. So when you save a file in /photos/+ADD/photo/vacation,
it will be saved in /photos and be tagged as "photo" and "vacation".
Off-course you also want the ability to use new tags while in the save
dialog. This is implemented by making a new directory when in the +ADD
folder or any of its subfolders.
In terminal this goes fine. In the GUI (Finder), this works too. Its
only when using the save dialog that things get weird. That is, after
adding the folder ("tag"), I see the content of it (other tags) for a
moment and then the save dialog jumps back to the parent directory and
doesn't even show the new folder ("tag"). However, when I select
another folder ("tag") and see a list of all other possible folders
("tags"), the new folder is in there!
The tag information is stored in a xapian database. When a tag is
added by executing the mkdir, it is added to the database. When a
readdir on +ADD is performed, all tags from the database are displayed
as folders. A readdir on /+ADD/tag1 returns a list of all tags minus
"tag1".
All this testing is done on an OS X Leopard installation. As an
example I used an empty database and filesystem (except for some
virtual folders that are always there). I try to save a file in the
root and want to tag it as "test", thus go to /+ADD and try a mkdir of
"test". After doing so, the save dialog jumps back to the root display.
Below I'm including the output from debug. Lines prefixed by "------"
are lines I put out myself. This is simply the name of the method
called and the values of the parameters. There are also some getattr
requests on files starting with "._". Mac OS X uses this to store
metadata of files on storage not formatted as HFS.
Thanks in advance,
Karel
