tmpfile() not being closed

[GoogleCodeExporter]

"The /tmp partition is filling up on the server because s3fs is not releasing
the file handles to its temporary files correctly"

I just tested and it also happens even when the partition is 5 gig.  
I originally thought the bug was only when the file got stuck in the middle of 
the
copy (example 1.7 gig file copying with 1 gig /tmp partition).  But the copy 
went
through perfect.  The /tmp  size was not released.

3 questions:
1) Is there a way to manually release the files until the bug is fixed?
2) Is there a way to use a different /tmp folder so the stability of the server 
is
not affected?
3) If not, is there a way to limit the s3fs to 80% of the /tmp directory so the
server doesn't crash?

1) umount and then mount
2) s3fs uses tmpfile()... see "man tmpfile"
3) disk quota?

Sorry, i just noticed that it did release it when the copy succeeded.

Thanks for the answer on #2.
But where is the /tmp directory defined in your code? 
We want to change it to another location.

Hi Sammy-
s3fs uses tmpfile() to create temporary files; I had a quick peek on how to 
configure
the location (e.g., TMPDIR environment variable) but had no luck;
either that or configurable tmpdir would need to be added as a feature

A review of the code shows that all file descriptors that are associated with 
tmpfile() are closed in one way or another. Documentation for tmpfile() states:

"The file is deleted automatically when it is closed or when the program 
terminates."

Closing this old issue.
