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

Kyle Havlovitz	198ed6076d	Clean up subprocess handling and make shell use optional (#3509) ... * Clean up handling of subprocesses and make using a shell optional * Update docs for subprocess changes * Fix tests for new subprocess behavior * More cleanup of subprocesses * Minor adjustments and cleanup for subprocess logic * Makes the watch handler reload test use the new path. * Adds check tests for new args path, and updates existing tests to use new path. * Adds support for script args in Docker checks. * Fixes the sanitize unit test. * Adds panic for unknown watch type, and reverts back to Run(). * Adds shell option back to consul lock command. * Adds shell option back to consul exec command. * Adds shell back into consul watch command. * Refactors signal forwarding and makes Windows-friendly. * Adds a clarifying comment. * Changes error wording to a warning. * Scopes signals to interrupt and kill. 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

James Phillips	9258506dab	Adds simple rate limiting for client agent RPC calls to Consul servers. (#3440) ... * Added rate limiting for agent RPC calls. * Initializes the rate limiter based on the config. * Adds the rate limiter into the snapshot RPC path. * Adds unit tests for the RPC rate limiter. * Groups the RPC limit parameters under "limits" in the config. * Adds some documentation about the RPC limiter. * Sends a 429 response when the rate limiter kicks in. * Adds docs for new telemetry. * Makes snapshot telemetry look like RPC telemetry and cleans up comments.	7 years ago
