[ https://issues.apache.org/jira/browse/MESOS-2160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14505624#comment-14505624 ]

-----------------------------------------------
commit da607079b473d34d06031943e69cd8e0c24073c5
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:12:12 2015 -0700
Wired up test allocator to allocator tests.
Same typed tests are used for built-in and modularized allocators.

commit 54b5bdccb43f724353fd3112115e980360e53c9a
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:11:58 2015 -0700
Provided a factory for allocator in tests.
The factory creates allocator instances in a way identical to how
instances from modules are created. It allows us to use same typed tests
for built-in and modularized allocators.

commit ab48d54c0250bffc5542bf68afd648e6a12025ad
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:11:37 2015 -0700
Refactored TestAllocator and allocator text fixture.
TestAllocator owns a pointer to a real allocator. Each test should
instantiate and destroy Allocator instances explicitly to avoid not
expected calls.

commit c97c93e3ee5c6f7286c99b5e623cdcff663fd19b
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:11:20 2015 -0700
Moved allocator actions before TestAllocator.
The allocator actions should be defined before they are used in
TestAllocator, despite it compiles now since TestAllocator is a
template.

commit a5f270fe513ecb50021eb06d429a1a84e260f98a
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:11:03 2015 -0700
Added a test allocator module.
The test allocator module is a built-in HierarchicalDRFAllocator put in
a module.
NOTE: Here we add harness code to load the module, tests will be wired
up later in the patch stack.

Added support for allocator modules.

commit aabebb14c22492552c77ed471ad56a51c87d4ee1
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:10:27 2015 -0700
Moved RoleInfo to mesos.master namespace.
Since the Allocator is a public interface now, there is no reason to
keep RoleInfo in mesos.internal. It is ok to change the package because
RoleInfo is used solely by Master and Allocator, hence there is no
external communication affected.

commit f1fc3d76de93b0149e2797e3923f4bf939037c98
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:10:07 2015 -0700
Moved allocator to public headers.
This is required for out-of-tree allocator modules. RoleInfo protobuf
message has to be extracted into its own public proto file.

commit 97dce737c0ea8822e37f6eb13cc195039f77c623
Author: Alexander Rukletsov <ru...@gmail.com>
Date: Tue Apr 21 12:09:09 2015 -0700
Removed Master::Flags dependency from Allocator.
On the way to moving allocator to public includes we need to remove the
dependency to internal Master::Flags type.

> Currently Mesos supports only the DRF allocator, changing which requires hacking Mesos source code, which, in turn, sets a high entry barrier. Allocator modules give an easy possibility to tweak resource allocation policy. This will enable swapping allocation policies without the necessity to edit Mesos source code. Custom allocators may be written by everybody and does not need be distributed together with Mesos.
