Description Mark Wu 2012-06-18 01:45:48 UTC
Description of problem:
We found the temporary file is left behind when the sed option '--copy' is used.
This problem happens when vdsm manipulate libvirt's configuration.  Vdsm has to use the option '--copy' since the system call 'rename' is not allowed on bind-mount files (on ovirt node). I can't see the point of remaining the temporary file. My understanding is that with and without '--copy' should be just different ways(truncate+cp vs rename) to change the file in pace. So I think the temporary file should be removed after done.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
sed -i --copy -e 's/todo/done/' my_todo_list
then a temporary file like 'sedcMkUCu' was remained after the operation done.

Actual results:

Expected results:
No temporary file is removed after done.

Proposed patch to fix the issue

This patch should fix the issue when applied to the fedpkg repository. I'll build testing packages for you tomorrow.
There was a problem with the ported patch - it wasn't ported entirely and the ck_fcopy function was left behind.

I changed the patch a little bit more to reflect what the functions ck_fcmove and ck_fccopy do. I built a package with this patch on
so you can test it if you want to.
Thank you.
