Hello,
I am annoyed by a curious phenomenon.
When I access to my Mac/OSX PowerBook from Plan 9 terminal (in hosted
VirtualPC),
ls command of Plan 9 terminal does not respond in a special directory:
a mounted directory of remote file server.
Of cause my PowerBook responds the directory: /Volumes/kenji
-bash$ ls -l /Volumes
total 8
lrwxr-xr-x 1 root admin 1 Mar 27 11:35 Macintosh HD -> /
drwxrwxrwx 26 arisawa arisawa 840 Mar 30 14:30 kenji
-bash$ ls -l /Volumes/kenji
total 16
drwxrwxrwx 2 arisawa arisawa 264 Feb 26 16:56 Network Trash
Folder
drwxrwxrwx 47 arisawa arisawa 1554 Mar 5 17:28 Private
...
drwxrwxrwx 4 arisawa arisawa 264 Feb 26 20:22 travel
-bash$
I found u9fs falls into infinite loop in the directory.
I added
fprint(2,"rread...\n");
and
fprint(2,"dirread:%s\n", fid->dirent->d_name);
in u9fs.c
void
rread(Fcall *rx, Fcall *tx)
{
char *e, *path;
uchar *p, *ep;
int n;
Fid *fid;
Dir d;
struct stat st;
fprint(2,"rread...\n");
...
if(strcmp(fid->dirent->d_name, ".") == 0
|| strcmp(fid->dirent->d_name, "..") == 0){
fid->dirent = nil;
continue;
}
fprint(2,"dirread:%s\n", fid->dirent->d_name);
path = estrpath(fid->path, fid->dirent->d_name, 0);
memset(&st, 0, sizeof st);
...
}
Then u9fs.log shows:
rread...
dirread:Network Trash Folder
dirread:Temporary Items
dirread:photo

I don't know why this loop happens, and I don't know how to prevent
the loop.
Suggestion welcome.
