LockSet: handle empty case

A LockSet is mostly useful when it has some locks in it. On the other hand
there are cases in which it must function even when empty. For example if a
cluster has no instances in it there's no reason why locking all of them
shouldn't work anyway. This patch adds test code for that situation and...

LockSet: add missing check code

This check that no operation had been performed before release() was missing in

LockSet: make acquire() able to get the whole set

This new functionality makes it possible to acquire a whole set, by passing
"None" to the acquire() function as the list of elements. This will avoid new
additions to the set, and then acquire all the current elements. The list of...

LockSet: improve remove() api

Lockset's remove() function used to return a list of locks we failed to remove.
Rather than doing this we'll return a list of removed locks, so it's more
similar to how acquire() behaves. This patch also fixes the relevant unit tests....

LockSet: make acquire() return the set of names

In a LockSet acquire() returned True on success. This code changes that to
return a set containing the names of the elements acquired. This is still a
true value if we acquired any lock but is slightly more useful (because if...

Initial GanetiLockManager implementation

LockManager should be used, the class itself and its test cases.

LockSet implementation and unit tests

A LockSet represents locking for a set of resources of the same type. A thread
can acquire multiple resources at the same time, and release some or all of
them, but cannot acquire more resources incrementally at different times...

Add a few SharedLock delete() tests

- Check that even a shared acquire() fails on a deleted lock
- Check that delete() fails on a lock you share (must own it or nothing)

These are assumptions I build on in future code, so better check for them.
Currently no code change is necessary for them to be valid....

SharedLock: fix a wrong unit-test helper code

The _doItDelete helper code was supposed to be used to dispatch threads that
