this is mainly to ensure integration tests (which all end in _test)
are properly bossed around for their imports
I had to adjust some of the _test files to adhere to existing
reverse_rules specified elsewhere
The service allocator is used to allocate ip addresses for the
Service IP allocator and NodePorts for the Service NodePort
allocator. It uses a bitmap backed by etcd to store the allocation
and tries to allocate the resources directly from the local memory
instead from etcd, that can cause issues in environment with
high concurrency.
It may happen, in deployments with multiple apiservers, that the
resource allocation information is out of sync, this is more
sensible with NodePorts, per example:
1. apiserver A create a service with NodePort X
2. apiserver B deletes the service
3. apiserver A creates the service again
If the allocation data of apiserver A wasn't refreshed with the
deletion of apiserver B, apiserver A fails the allocation because
the data is out of sync. The Repair loops solve the problem later,
but there are some use cases that require to improve the concurrency
in the allocation logic.
We can try to not do the Allocation and Release operations locally,
and try instead to check if the local data is up to date with etcd,
and operate over the most recent version of the data.
This is gross but because NewDeleteOptions is used by various parts of
storage that still pass around pointers, the return type can't be
changed without significant refactoring within the apiserver. I think
this would be good to cleanup, but I want to minimize apiserver side
changes as much as possible in the client signature refactor.
The `TooLong` validation message mentioned characters, but the `len`
function actually measures bytes, no characters. This switches it over
to use bytes.
Characters are mostly an illusory concept anyway -- a vain attempt to
shield our minds against the lovecraftian nightmares that comes from
attemping to truly comprehend that eldritch treatise known as the
Unicode standard. Which is to say: measuring things in characters is
hard and mostly ambiguous, and probably not what we meant to do.
go fmt
make func private
refactor config_test
Two primary refactorings:
1. config test checkPath method is now each a distinct test
run (which makes it easier to see what is actually failing)
2. TestNewWithDelegate's root path check now parses the json output and
does a comparison against a list of expected paths (no more whitespace
and ordering issues when updating this test, yay).

TestWatchBasedManager was racing with the default namespace creation.
To fix that flake and to ensure integration tests using a shared etcd
don't accidentally overlap in the future, move the three main tests
using the default namespace to separate namespaces, and have
TestWatchBasedManager create that namespace before it runs.
Make StartTestServer wait for default namespace creation, which will
reduce other flakes until future changes completely remove use of default
namespace.
From a failed integration run:
watch_manager_test.go:66: namespaces "default" not found
watch_manager_test.go:66: namespaces "default" not found
watch_manager_test.go:66: namespaces "default" not found
