Daniel Nephin e8312d6b5a testing: remove unnecessary calls to freeport
Previously we believe it was necessary for all code that required ports
to use freeport to prevent conflicts.

https://github.com/dnephin/freeport-test shows that it is actually save
to use port 0 (`127.0.0.1:0`) as long as it is passed directly to
`net.Listen`, and the listener holds the port for as long as it is
needed.

This works because freeport explicitly avoids the ephemeral port range,
and port 0 always uses that range. As you can see from the test output
of https://github.com/dnephin/freeport-test, the two systems never use
overlapping ports.

This commit converts all uses of freeport that were being passed
directly to a net.Listen to use port 0 instead. This allows us to remove
a bit of wrapping we had around httptest, in a couple places.

Daniel Nephin baa2b8628e consul: fix data race in leader CA tests
Some global variables are patched to shorter values in these tests. But the goroutines that read
them can outlive the test because nothing waited for them to exit.

This commit adds a Wait() method to the routine manager, so that tests can wait for the goroutines
to exit. This prevents the data race because the 'reset to original value' can happen
after all other goroutines have stopped.

RPC Timeout/Retries account for blocking requests (#8978) 2021-05-27 17:29:43 -04:00
Matt Keeler da31e0449e Move some things around to allow for license updating via config reload
The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.

Daniel Nephin f9cf2ec9ab lib/retry: allow jitter to exceed max wait.
I changed this in https://github.com/hashicorp/consul/pull/8802#pullrequestreview-500779357 because
exceeding the MaxWait seemed wrong, but as other have pointed out, that behaviour is probably correct.

When multiple waiters hit the max value, we don't want them to converge, so restore the behaviour of
allowing jitter to exceed max, and document it.

Daniel Nephin 6c09ab3dd8 cache: fix a bug with Prepopulate
Prepopulate was setting entry.Expiry.HeapIndex to 0. Previously this would result in a call to heap.Fix(0)
which wasn't correct, but was also not really a problem because at worse it would re-notify.

With the recent change to extract cachettl it was changed to call Update(idx), which would have updated
the wrong entry.

A previous commit removed the setting of entry.Expiry so that the HeapIndex would be reported
as -1, and this commit adds a test and handles the -1 heap index.

Add per-agent reconnect timeouts (#8781)
This allows for client agent to be run in a more stateless manner where they may be abruptly terminated and not expected to come back. If advertising a per-agent reconnect timeout using the advertise_reconnect_timeout configuration when that agent leaves, other agents will wait only that amount of time for the agent to come back before reaping it.

This has the advantageous side effect of causing servers to deregister the node/services/checks for that agent sooner than if the global reconnect_timeout was used.

IsErrEOF returns false when it should return true in a couple of cases:

1. if the error has been wrapped in another error (for example, if EOF
is wrapped in an RPC error)
2. if the error has been created from an Error field in an RPC response
(as it is the case in CallWithCodec in the net-rpc-msgpackrpc package
for example)

Daniel Nephin 63bad36de7 testing: disable global metrics sink in tests
This might be better handled by allowing configuration for the InMemSink interval and retail, and disabling
the global. For now this is a smaller change to remove the goroutine leak caused by tests because go-metrics
does not provide any way of shutting down the global goroutine.
