Review request for cloudstack, edison su and Wido den Hollander.
Bugs: CLOUDSTACK-2729
Repository: cloudstack-git
Description
-------
The storage pool issue (CLOUDSTACK-2729) is because of a bug in libvirt (https://bugzilla.redhat.com/show_bug.cgi?id=977706)
We need to prevent deleting a volume when refreshing the pool.
This patch use a simple file lock to implement it.
PS: I have tested another file lock similar to Read/Write file lock, but it was very unstable.

Testing
-------
Applied on 4.0.2 and 4.0.1
Testing On 4.0.1 From 20,June
3 nodes, create a VM on each node every 15 minutes. Destroy the VMs 5 minutes later. expunge.inteval = 600 (10 minutes), expunge.worker = 2
Testing On 4.0.2 From 01,July
2 nodes, create two VMs on each node every 5 minutes. Destroy the VMs 4 minutes later. expunge.inteval = 600 (10 minutes), expunge.worker = 2
Thanks,
Wei Zhou

I haven't tested the patch, but I'm missing some comments.
Can we add clear comments as to WHY this is in the code? Otherwise I'm afraid this will become legacy and in 6 months new committer won't have the slightest idea of why this is in there.

How about use the atomic semantics provided by createNewFile to coordinate between processes?
For example: lock(int wait) {
File lockFile = new File(lock-file-path);
while(wait) {
boolean havelock = false;
if (lockFile.createNewFile()) {
haveLock = true;
break;
}
Time.sleep(1000);
wait--;
}
return haveLock;
}
unlock() {
File lockFile = new File(path-of-lock-file);
lockFile.delete();
}
It's simpler version of lockfile: https://github.com/spearce/jgit/blob/master/org.eclipse.jgit/src/org/eclipse/jgit/storage/file/LockFile.java

if (!lockFile.exists()) { lockFile.createNewFile();
Above stanza is not atomic. If two threads coming into this code at the same time, both will succeed.
Maybe just if (lockFile.createNewFile()) is good enough?
