Yoann Fouquet	986148cfe5	[Fix] Service tags not added to health checks ... Since commit 9685bdcd0b, service tags are added to the health checks. Otherwise, when adding a service, tags are not added to its check. In updateSyncState, we compare the checks of the local agent with the checks of the catalog. It appears that the service tags are different (missing in one case), and so the check is synchronized. That increase the ModifyIndex periodically when nothing changes. Fixed it by adding serviceTags to the check. Note that the issue appeared in version 0.8.2. Looks related to #3259.	7 years ago

Frank Schroeder	0a9ac9749e	local state: replace multi-map state with structs ... The state of the service and health check records was spread out over multiple maps guarded by a single lock. Access to the maps has to happen in a coordinated effort and the tests often violated this which made them brittle and racy. This patch replaces the multiple maps with a single one for both checks and services to make the code less fragile. This is also necessary since moving the local state into its own package creates circular dependencies for the tests. To avoid this the tests can no longer access internal data structures which they should not be doing in the first place. The tests still don't compile but this is a ncessary step in that direction.	7 years ago

The anti-entropy code manages background synchronizations of the local state on a regular basis or on demand when either the state has changed or a new consul server has been added. This patch moves the anti-entropy code into its own package and decouples it from the local state code since they are performing two different functions. To simplify code-review this revision does not make any optimizations, renames or refactorings. This will happen in subsequent commits.	7 years ago

Frank Schröder	94f58199b1	agent: add option to discard health output (#3562) ... * agent: add option to discard health output In high volatile environments consul will have checks with "noisy" output which changes every time even though the status does not change. Since the output is stored in the raft log every health check update unblocks a blocking call on health checks since the raft index has changed even though the status of the health checks may not have changed at all. By discarding the output of the health checks the users can choose a different tradeoff. Less visibility on why a check failed in exchange for a reduced change rate on the raft log. * agent: discard output also when adding a check * agent: add test for discard check output * agent: update docs * go vet * Adds discard_check_output to reloadable config table. * Updates the change log.	7 years ago
preetapan	77c972f594	Fixes agent error handling when check definition is invalid. Distingu… (#3560) ... * Fixes agent error handling when check definition is invalid. Distinguishes between empty checks vs invalid checks * Made CheckTypes return Checks from service definition struct rather than a new copy, and other changes from code review. This also errors when json payload contains empty structs * Simplify and improve validate method, and make sure that CheckTypes always returns a new copy of validated check definitions * Tweaks some small style things and error messages. * Updates the change log.	7 years ago
James Phillips	bb12368eac	Makes RPC handling more robust when rolling servers. (#3561) ... * Adds client-side retry for no leader errors. This paves over the case where the client was connected to the leader when it loses leadership. * Adds a configurable server RPC drain time and a fail-fast path for RPCs. When a server leaves it gets removed from the Raft configuration, so it will never know who the new leader server ends up being. Without this we'd be doomed to wait out the RPC hold timeout and then fail. This makes things fail a little quicker while a sever is draining, and since we added a client retry AND since the server doing this has already shut down and left the Serf LAN, clients should retry against some other server. * Makes the RPC hold timeout configurable. * Reorders struct members. * Sets the RPC hold timeout default for test servers. * Bumps the leave drain time up to 5 seconds. * Robustifies retries with a simpler client-side RPC hold. * Reverts untended delete.	7 years ago

This avoids us trying to send SIGCHILD to the dead process. * Adds an error for shell=false for consul exec. * Adds notes about the deprecated script and handler fields. * De-nests an if statement.	7 years ago

Frank Schröder	12216583a1	New config parser, HCL support, multiple bind addrs (#3480) ... * new config parser for agent This patch implements a new config parser for the consul agent which makes the following changes to the previous implementation: * add HCL support * all configuration fragments in tests and for default config are expressed as HCL fragments * HCL fragments can be provided on the command line so that they can eventually replace the command line flags. * HCL/JSON fragments are parsed into a temporary Config structure which can be merged using reflection (all values are pointers). The existing merge logic of overwrite for values and append for slices has been preserved. * A single builder process generates a typed runtime configuration for the agent. The new implementation is more strict and fails in the builder process if no valid runtime configuration can be generated. Therefore, additional validations in other parts of the code should be removed. The builder also pre-computes all required network addresses so that no address/port magic should be required where the configuration is used and should therefore be removed. * Upgrade github.com/hashicorp/hcl to support int64 * improve error messages * fix directory permission test * Fix rtt test * Fix ForceLeave test * Skip performance test for now until we know what to do * Update github.com/hashicorp/memberlist to update log prefix * Make memberlist use the default logger * improve config error handling * do not fail on non-existing data-dir * experiment with non-uniform timeouts to get a handle on stalled leader elections * Run tests for packages separately to eliminate the spurious port conflicts * refactor private address detection and unify approach for ipv4 and ipv6. Fixes #2825 * do not allow unix sockets for DNS * improve bind and advertise addr error handling * go through builder using test coverage * minimal update to the docs * more coverage tests fixed * more tests * fix makefile * cleanup * fix port conflicts with external port server 'porter' * stop test server on error * do not run api test that change global ENV concurrently with the other tests * Run remaining api tests concurrently * no need for retry with the port number service * monkey patch race condition in go-sockaddr until we understand why that fails * monkey patch hcl decoder race condidtion until we understand why that fails * monkey patch spurious errors in strings.EqualFold from here * add test for hcl decoder race condition. Run with go test -parallel 128 * Increase timeout again * cleanup * don't log port allocations by default * use base command arg parsing to format help output properly * handle -dc deprecation case in Build * switch autopilot.max_trailing_logs to int * remove duplicate test case * remove unused methods * remove comments about flag/config value inconsistencies * switch got and want around since the error message was misleading. * Removes a stray debug log. * Removes a stray newline in imports. * Fixes TestACL_Version8. * Runs go fmt. * Adds a default case for unknown address types. * Reoders and reformats some imports. * Adds some comments and fixes typos. * Reorders imports. * add unix socket support for dns later * drop all deprecated flags and arguments * fix wrong field name * remove stray node-id file * drop unnecessary patch section in test * drop duplicate test * add test for LeaveOnTerm and SkipLeaveOnInt in client mode * drop "bla" and add clarifying comment for the test * split up tests to support enterprise/non-enterprise tests * drop raft multiplier and derive values during build phase * sanitize runtime config reflectively and add test * detect invalid config fields * fix tests with invalid config fields * use different values for wan sanitiziation test * drop recursor in favor of recursors * allow dns_config.udp_answer_limit to be zero * make sure tests run on machines with multiple ips * Fix failing tests in a few more places by providing a bind address in the test * Gets rid of skipped TestAgent_CheckPerformanceSettings and adds case for builder. * Add porter to server_test.go to make tests there less flaky * go fmt	7 years ago

Frank Schröder	a3934c263c	acl: consolidate error handling (#3401) ... The error handling of the ACL code relies on the presence of certain magic error messages. Since the error values are sent via RPC between older and newer consul agents we cannot just replace the magic values with typed errors and switch to type checks since this would break compatibility with older clients. Therefore, this patch moves all magic ACL error messages into the acl package and provides default error values and helper functions which determine the type of error.	7 years ago

James Phillips	0881e46111	Cleans up version 8 ACLs in the agent and the docs. (#3248) ... * Moves magic check and service constants into shared structs package. * Removes the "consul" service from local state. Since this service is added by the leader, it doesn't really make sense to also keep it in local state (which requires special ACLs to configure), and requires a bunch of special cases in the local state logic. This requires fewer special cases and makes ACL bootstrapping cleaner. * Makes coordinate update ACL log message a warning, similar to other AE warnings. * Adds much more detailed examples for bootstrapping ACLs.

Frank Schroeder	ea5b0f2c7c	agent: fix 'consul leave' shutdown race (#2880) ... When the agent is triggered to shutdown via an external 'consul leave' command delivered via the HTTP API then the client expects to receive a response when the agent is down. This creates a race on when to shutdown the agent itself like the RPC server, the checks and the state and the external endpoints like DNS and HTTP. This patch splits the shutdown process into two parts: * shutdown the agent * shutdown the endpoints (http and dns) They can be executed multiple times, concurrently and in any order but should be executed first agent, then endpoints to provide consistent behavior across all use cases. Both calls have to be executed for a proper shutdown. This could be partially hidden in a single function but would introduce some magic that happens behind the scenes which one has to know of but isn't obvious. Fixes #2880	8 years ago

Frank Schroeder	90c83a32b5	agent: fix 'consul leave' shutdown race (#2880) ... When the agent is triggered to shutdown via an external 'consul leave' command delivered via the HTTP API then the client expects to receive a response when the agent is down. This creates a race on when to shutdown the agent itself like the RPC server, the checks and the state and the external endpoints like DNS and HTTP. Ideally, the external endpoints should be shutdown before the internal state but if the goal is to respond reliably that the agent is down then this is not possible. This patch splits the agent shutdown into two parts implemented in a single method to keep it simple and unambiguos for the caller. The first stage shuts down the internal state, checks, RPC server, ... synchronously and then triggers the shutdown of the external endpoints asychronously. This way the caller is guaranteed that the internal state services are down when Shutdown returns and there remains enough time to send a response. Fixes #2880	8 years ago
