* Implementation of Weights Data structures
Adding this datastructure will allow us to resolve the
issues #1088 and #4198
This new structure defaults to values:
```
{ Passing: 1, Warning: 0 }
```
Which means, use weight of 0 for a Service in Warning State
while use Weight 1 for a Healthy Service.
Thus it remains compatible with previous Consul versions.
* Implemented weights for DNS SRV Records
* DNS properly support agents with weight support while server does not (backwards compatibility)
* Use Warning value of Weights of 1 by default
When using DNS interface with only_passing = false, all nodes
with non-Critical healthcheck used to have a weight value of 1.
While having weight.Warning = 0 as default value, this is probably
a bad idea as it breaks ascending compatibility.
Thus, we put a default value of 1 to be consistent with existing behaviour.
* Added documentation for new weight field in service description
* Better documentation about weights as suggested by @banks
* Return weight = 1 for unknown Check states as suggested by @banks
* Fixed typo (of -> or) in error message as requested by @mkeeler
* Fixed unstable unit test TestRetryJoin
* Fixed unstable tests
* Fixed wrong Fatalf format in `testrpc/wait.go`
* Added notes regarding DNS SRV lookup limitations regarding number of instances
* Documentation fixes and clarification regarding SRV records with weights as requested by @banks
* Rephrase docs
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
This brings down the test run from 108 sec to 15 sec.
There is an occasional port conflict because of the nature
the next port is chosen. So far it seems rare enough to live
with it.
This patch adds support for a custom check id and name when
registering a service.
This is achieved by adding a CheckID and a Name field to the
CheckType structure which is used to register checks with a
service and when returning health check definitions.
CheckDefinition is a superset of CheckType which duplicates
some of the fields of CheckType. This patch decouples these
two structures by removing the embedding of CheckType in
CheckDefinition.
Fixes#3047
This patch adds a new internal interface clientServer
which defines the common methods of consul.Client and
consul.Server. This allows to replace the following
code
if a.server != nil {
a.server.do()
} else {
a.client.do()
}
with
a.delegate.do()
In case a specific type is required a type check can
be performed:
if srv, ok := a.delegate.(*consul.Server); ok {
srv.doSrv()
}
This creates a simplified helper for temporary directories and files.
All path names are prefixed with the name of the current test.
All files and directories are stored either in /tmp/consul-test
or /tmp if the former could not be created.
Using the system temp dir breaks some tests on macOS where the unix
socket path becomes too long.
macOS displays a firewall warning dialog when an unsigned
application is trying to bind to a non-loopback address.
This patch updates some test configurations to ensure binding
to a loopback address where possible to suppress these warnings.
This patch removes duplicate internal copies of constants in the structs
package which are also defined in the api package. The api.KVOp type
with all its values for the TXN endpoint and the api.HealthXXX constants
are now used throughout the codebase.
This resulted in some circular dependencies in the testutil package
which have been resolved by copying code and constants and moving the
WaitForLeader function into a separate testrpc package.
Ended up removing the leader_test.go server address change test as part
of this. The join was failing becase we were using a new node name with
the new logic here, but realized this was hitting some of the memberlist
conflict logic and not working as we expected. We need some additional
work to fully support address changes, so removed the test for now.
This has the next wave of RTT integration with the router and also
factors some common RTT-related helpers out to lib. While we were
in here we also got rid of the coordinate disable config so we don't
need to deal with the complexity in the router (there was never a
user-visible way to disable coordinates).
Given a list of HealthChecks, this determines the "best" status for the
collective group. This is useful for nodes and services, which may have
multiple checks associated with them.
Log a warning instead of a success message when attempting to deregister a nonexistent service. In Consul 0.8 this can be changed to giving an error outright, but for now we can keep the idempotent delete behavior.
* * adding cli config and config file support for specifying the serf wan and lan bind addresses
* updating documentation for serf wan and lan options
Fixes#2007
* Cleans up some small things from #2380.
* Uses the bind default for the agent test for Serf WAN and LAN.
* Test fixes in health_endpoint_test.go, agent_endpoint_test.go and rtt_test.go
* Don't reuse the same agent config in TestAgent_ReconnectConfigSettings
