[fuse-devel] After 'readdir' operation, gettattr for parent directory is getting called in the midst, even when gettattr for the underlying files/folders is not over

[shobhit p. <sho...@gm...>]

Hello

I hope you are doing well. I am Shobhit Puri, pursuing my undergraduate
from Indian Institute of Information Technology, India.
I am working on integrating FUSE with Globus gridftp client API.

I am facing an error sometimes when another operation wants to use the
globus handle which is already occupied with some other operation.
For eg:- In terms of FUSE operations:
After a call to readdir operation the getattr operation for all the
underlying files and folders in called. Now, if the number of files are
more in number, then, while the gettattr function is already in  progress
for the underlying
files, FUSE calls for getattr operation for the parent directory before the
getattr for the underlying files is over. This gives the following errors:
sometimes it shows "operation already in progress", sometimes "Assertion
node failed in file globus_ftp_client.c at line 331".

I was thinking of creating a connection pool in globus and allocating some
other handle from the pool to the process who is trying to access one
handle which is already in use.
Have I understood the problem clearly? Is it a problem of FUSE code? I am
asking because when I just use FUSE program without integrating it with the
globus gridftp, their is not such call in the midst, when other getattr
operation are still going.

Can you please guide me regrading the same? I would be really thankful to
you for your kind help.

Thanks in advance
With best regards
