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.	3 years ago

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.	3 years ago

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.	4 years ago

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.	4 years ago

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.	4 years ago

Matt Keeler	38f5ddce2a	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.	4 years ago

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.	4 years ago

Daniel Nephin	a46ce3d841	decode: recursively unslice opaque config Also handle []interface{} in HookWeakDecodeFromSlice Without this change only the top level []map[string]interface{} will be unpacked as a single item. With this change any nested config will be unpacked.	5 years ago
Daniel Nephin	75cbbe2702	config: add HookWeakDecodeFromSlice Currently opaque config blocks (config entries, and CA provider config) are modified by PatchSliceOfMaps, making it impossible for these opaque config sections to contain slices of maps. In order to fix this problem, any lazy-decoding of these blocks needs to support weak decoding of []map[string]interface{} to a struct type before PatchSliceOfMaps is replaces. This is necessary because these config blobs are persisted, and during an upgrade an older version of Consul could read one of the new configuration values, which would cause an error. To support the upgrade path, this commit first introduces the new hooks for weak decoding of []map[string]interface{} and uses them only in the lazy-decode paths. That way, in a future release, new style configuration will be supported by the older version of Consul. This decode hook has a number of advantages: 1. It no longer panics. It allows mapstructure to report the error 2. It no longer requires the user to declare which fields are slices of structs. It can deduce that information from the 'to' value. 3. It will make it possible to preserve opaque configuration, allowing for structured opaque config.	5 years ago
Daniel Nephin	99eb583ebc	Replace goe/verify.Values with testify/require.Equal (#7993 ) * testing: replace most goe/verify.Values with require.Equal One difference between these two comparisons is that go/verify considers nil slices/maps to be equal to empty slices/maps, where as testify/require does not, and does not appear to provide any way to enable that behaviour. Because of this difference some expected values were changed from empty slices to nil slices, and some calls to verify.Values were left. * Remove github.com/pascaldekloe/goe/verify Reduce the number of assertion packages we use from 2 to 1	5 years ago
Daniel Nephin	6a2d7d77c0	config: use the new HookTranslateKeys instead of lib.TranslateKeys With the exception of CA provider config, which will be migrated at some later time.	5 years ago
Daniel Nephin	1a039393f5	config: add HookTranslteKeys This hook replaces lib.TranslateKeys and has a number of advantages: 1. Primarily, aliases for fields are defined on the field itself, making the aliases much easier to maintain, and more obvious to the reader. 2. TranslateKeys translation rules are not aware of structure. It could very easily incorrectly translate a key on one struct that was intended to be a translation rule for a completely different struct, leading to very hard to debug errors. The hook removes the need for the unexpected "translation rule is an empty string to indicate stop traversal" special case. 3. TranslateKeys attempts to duplicate a bunch of tree traversal logic that already exists in mapstructure. Using mapstructure for traversal removes the need to traverse the entire structure multiple times, and makes the behaviour more obvious to the reader. This change is being made to enable a future change of replacing PatchSliceOfMaps. TranslateKeys sits in between PatchSliceOfMaps and mapstructure.Decode, so it must be converted to a hook first, before PatchSliceOfMaps can be replaced by a decode hook.	5 years ago

R.B. Boyer	ddd0a13e27	agent: handle re-bootstrapping in a secondary datacenter when WAN federation via mesh gateways is configured (#7931 ) The main fix here is to always union the `primary-gateways` list with the list of mesh gateways in the primary returned from the replicated federation states list. This will allow any replicated (incorrect) state to be supplemented with user-configured (correct) state in the config file. Eventually the game of random selection whack-a-mole will pick a winning entry and re-replicate the latest federation states from the primary. If the user-configured state is actually the incorrect one, then the same eventual correct selection process will work in that case, too. The secondary fix is actually to finish making wanfed-via-mgws actually work as originally designed. Once a secondary datacenter has replicated federation states for the primary AND managed to stand up its own local mesh gateways then all of the RPCs from a secondary to the primary SHOULD go through two sets of mesh gateways to arrive in the consul servers in the primary (one hop for the secondary datacenter's mesh gateway, and one hop through the primary datacenter's mesh gateway). This was neglected in the initial implementation. While everything works, ideally we should treat communications that go around the mesh gateways as just provided for bootstrapping purposes. Now we heuristically use the success/failure history of the federation state replicator goroutine loop to determine if our current mesh gateway route is working as intended. If it is, we try using the local gateways, and if those don't work we fall back on trying the primary via the union of the replicated state and the go-discover configuration flags. This can be improved slightly in the future by possibly initializing the gateway choice to local on startup if we already have replicated state. This PR does not address that improvement.
