Pierre Souchay	0b7f620dc6	Allow to control the number of A/AAAA Record returned by DNS ... This allows to have randomized resource records (i.e. each answer contains only one IP, but the IP changes every request) for A, AAAA records. It will fix https://github.com/hashicorp/consul/issues/3355 and https://github.com/hashicorp/consul/issues/3937 See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509 for details. It basically add a new option called `a_record_limit` and will not return more than a_record_limit when performing A, AAAA or ANY DNS requests. The existing `udp_answer_limit` option is still working but should be considered as deprecated since it works only with DNS clients not supporting EDNS.	7 years ago

Frank Schröder	874e350b2f	config: add -config-format option (#3626) ... * config: refactor ReadPath(s) methods without side-effects Return the sources instead of modifying the state. * config: clean data dir before every test * config: add tests for config-file and config-dir * config: add -config-format option Starting with Consul 1.0 all config files must have a '.json' or '.hcl' extension to make it unambigous how the data should be parsed. Some automation tools generate temporary files by appending a random string to the generated file which obfuscates the extension and prevents the file type detection. This patch adds a -config-format option which can be used to override the auto-detection behavior by forcing all config files or all files within a config directory independent of their extension to be interpreted as of this format. Fixes #3620	7 years ago
Frank Schroeder	2e7ed2fd86	Merge pull request #3585 from hashicorp/document-runtime-config ... Moving the previous `agent/config.go` documentation to `agent/config/runtime.go`.	7 years ago
Frank Schroeder	5bfb2808f9	Merge pull request #3598 from hashicorp/issue-3397-error-with-extra-flags ... The `consul agent` command was ignoring extra command line arguments which can lead to confusion when the user has for example forgotten to add a dash in front of an argument or is not using an `=` when setting boolean flags to `true`. `-bootstrap true` is not the same as `-bootstrap=true`, for example. Since all command line flags are known and we don't expect unparsed arguments we can return an error. However, this may make it slightly more difficult in the future if we ever wanted to have these kinds of arguments. Fixes #3397	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
Frank Schröder	759ef8a1d4	config: add generic method to translate between CamelCase and snake_case (#3557) ... * doc: document discrepancy between id and CheckID * doc: document enable_tag_override change * config: add TranslateKeys helper TranslateKeys makes it easier to map between different representations of internal structures. It allows to recursively map alias keys to canonical keys in structured maps. * config: use TranslateKeys for config file This also adds support for 'enabletagoverride' and removes the need for a separate CheckID alias field. * config: remove dead code * agent: use TranslateKeys for FixupCheckType * agent: translate enable_tag_override during service registration * doc: add '.hcl' as valid extension * config: map ScriptArgs to args * config: add comment for TranslateKeys	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	e84c2b2edd	Metrics service prefix (#3498) ... * metrics: replace statsite_prefix with service_prefix The metrics prefix isn't statsite specific and is in fact used for all metrics providers. Since we are deprecating fields anyway we should fix this one as well. Fixes #3293 * Updates docs and sorts telemetry section. * Renames to "metrics_prefix" to disambiguate with Consul services. * Updates the change log.	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
