Changelog

Major Changes between 0.6.4.7 and 0.7.0

  • The method of configuring the ConsulClient has been reworked. It now uses Actions to configure the options inside itself - e.g. var client = new ConsulClient((cfg) => { cfg.Datacenter = "us-west-2"; } See the file Consul.Test/ClientTest.cs and the test method Client_Constructors() for more examples. The old method will work but has been made Obsolete.
  • The ExecuteAbortableLocked method has been removed.
  • Requests to use the X-Consul-Token header instead of the ?token= query parameter. This may break use of ACLs with very old Consuls (< 0.6.0). Please file an issue if this breaks for you.

2017-01-17

  • Fixed up a few leaking tasks in Sessions, Locks and Semaphores, as well as properly waiting for the previously-leaked tasks to complete. Also made some tasks Long Running in the TPL sense.

2017-01-03 (0.7.2.0)

  • New APIs ported:
    • Snapshot API. Requires >= Consul 0.7.1 to use.
    • Keyring API. Requires >= Consul 0.7.2 to use.
    • Agent Leave/Reload APIs. Requires >= Consul 0.7.2 to use.
  • Added TLSSkipVerify and DeregisterCriticalServiceAfter to the AgentServiceCheck class. Requires >= Consul 0.7.0 to use.
  • Added Health.AggregatedStatus() extension method to any IEnumerable<HealthCheck> to roll up a set of checks. Can be used with any version of Consul.
  • Renamed CheckStatus to HealthStatus. This affects the AgentServiceCheck and AgentCheck classes.
  • Changed the Health.HealthCheck Status field to be of type HealthStatus instead of string.

2016-12-29 (0.7.0.5)

  • Added missing nuget info to project.json. Thanks @latop2604!

2016-12-20

  • Added a couple missing interfaces to IConsulClient. Thanks @chrishoffman!

2016-11-02

  • Cleaned up a few minor logic errors and made disposal of internally-used CancellationTokenSources a lot more explicit instead of leaking them.

2016-10-10

  • Revert inadvertent upgrade to .NET 4.5.1.

2016-09-21

  • Fixed a variety of bugs that could cause sessions to be destroyed if provided to a Lock or Semaphore via a LockOptions or SemaphoreOptions object.

2016-08-17

  • Ported in changes from the Consul Go API for 0.7.0. Most of these require 0.7.0 servers/agents. The changes are:
    • Atomic transactions for the KV store
    • Only retry locks/semaphores on Consul errors, not on all errors
    • Add the Near property to Prepared Queries
    • Add Query Templates to Prepared Queries, with regex filtering
    • Change all requests to use the X-Consul-Token header instead of the ?token= query parameter.
    • Add the ability to deregister a service that has been critical for an arbitrary period of time.
    • Signal WAN address translation and add the ability to look up the WAN and LAN addresses if address translation is being used.
    • Added Operator API to allow Raft editing.

2016-08-03

  • Added the ability to set LockOpts.LockRetryTime. Thanks @pfrejlich!

2016-07-10

  • Add an optional CancellationToken parameter to every method that ends up doing an HTTP request. Some of these can create an unstable Consul state (e.g. allowing the release of a distribted Semaphore to be canceled) but in many cases they should only be used if the call can possibly fail and a secondary timeout is needed.

2016-07-07

  • Add .NET Core port and build process thanks to work by @akatz0813.
  • Converted all Locks and Semaphores to be totally async thanks to work by @mjgoethe.
  • Entirely removed the method ExecuteAbortableLocked and all functionality around aborting a thread based on a Consul lock.
  • Reworked configuration of the ConsulClient to use Action<T> to configure options.

2016-06-10

  • Correct the behavior of LockTryOnce/SemaphoreTryOnce so that it now properly waits one multiple of the WaitTime before exiting in case of it already being held.

2016-05-27

  • Disable Client Certificates on Mono since the certificate handler is not implemented at the Mono library level.

2016-05-24

  • Added missing CancellationToken overrides to allow long polling for Catalog.Node() and Catalog.Service().

2016-05-16

  • Fixed configuration reuse between multiple clients so multiple ConsulClients that exist one after the other that both reference the same configuration do not spuriously dispose of part of the ConsulClientConfiguration.

2016-04-29

  • The Newtonsoft.Json DLL is now ILMerged into the Consul DLL, so there should be no more issues with mismatched JSON.NET versions in user projects. Thanks @grounded042!

2016-03-23

  • Fix a bug where setting ConsulClientConfiguration.WaitTime would cause 400 Bad Request responses. Also converted QueryOptions.WaitTime to a nullable timespan to match the ConsulClientConfiguration property of the same name/purpose.

2016-03-19

  • Fix a bug where the StatusCode was not being set correctly on some result types.

2016-03-16

  • Port in Consul 0.6.4 API since 0.6.4 is now released, which was just an update to UpdateTTL and a rename of some of the strings.
  • Moved all the helper objects (TTLStatus, CheckStatus.Passing, etc.) to reference static readonly instances to cut down on allocation and ease comparison.
  • Marked AbortableLock obselete since Thread.Abort doesn't exist in DNXCore and it's contrary to the Task philosophy to abort threads.

2016-03-15

2016-03-10

  • Added a ConsulClient(ConsulClientConfiguration, HttpClient) constructor that allows a user to pass in a custom HttpClient to set a custom proxy setting/timeout.

2016-03-04

  • Fixed double-encoding of UpdateTTL note argument.

2016-02-24

  • Removed use of PushStreamContent to fix Mono problems.

2016-02-10

  • Added the ability to use Client Certificates to authenticate a client against a Consul agent endpoint that is protected by some other service. See the ClientCertificate property of ConsulClientConfiguration. Thanks @AndyRB!
  • Fixed a possible deadlock in the Session RenewPeriodic method.

2016-02-09

  • Implemented the IDisposable Pattern for the ConsulClient class. ConsulClient objects should now have Dispose() called on them to properly clean up. Thanks @TMaster!
  • Cleaned up the Prepared Queries endpoint stack.
  • Fixed a timing bug in one of the client execute calls.
  • Added Docker checks
  • Added the ability for Semaphores and Locks to ride out brief periods of failure using the MonitorRetries and MonitorRetryTime fields in LockOptions and SemaphoreOptions classes.
  • Added the ability for Semaphores and Locks to have configurable WaitTime values, as well as to operate in TryOnce mode, which means it attempts to acquire once and throws an exception if the acquisition was not successful. To use these, set the LockWaitTime and LockTryOnce fields on the LockOptions class and the SemaphoreWaitTime and SemaphoreTryOnce fields on the SemaphoreOptions class.

2016-02-07

  • Reduce the callstack and task overhead by returning the originating Task where possible. Thanks @TMaster!

2016-01-12

  • Rewrote entire API to be async.
  • Added Prepared Queries from Consul 0.6.0.

2015-11-21

  • Reworked the entire Client class to use System.Net.HttpClient as its underpinning rather than WebRequest/WebResponse.
  • Moved all tests to Xunit.
  • Converted all uses of System.Web.HttpUtility.UrlPathEncode to System.Uri.EscapeDataString.

2015-11-09

  • Added coordinates API. WARNING: No check is done to see if the API is available. If used against a 0.5.2 agent, an exception will be thrown because the agent does not understand the coordinate URL.
  • Fixed bug in tests for session renewal.

2015-11-03

  • Fixed a bug where the node name was not deserialized when using the Catalog.Nodes() endpoint. Thanks @lockwobr!
  • Fixed a bug where a zero timespan could not be specified for Lock Delays, TTLs or Check Intervals. Thanks @eugenyshchelkanov!

2015-10-24

  • Port in changes from hashicorp/consul master:
    • Add TCP check type
    • BEHAVIOR CHANGE: Changed Session.Renew() to now throw a SessionExpiredException when the session does not exist on the Consul server
    • BEHAVIOR CHANGE: Changed all the KV write methods (Put, Delete, DeleteTree, DeleteCAS, CAS, Release, Acquire) to throw an InvalidKeyPairException if the key path or prefix begins with a / character.
  • Fixed documentation typos.

2015-08-27

2015-08-26

  • Fix a NullReferenceException when the Consul connection is down and the WebException returned has an empty response.

2015-07-25

  • BREAKING CHANGE: Renamed Client class to ConsulClient and Config to ConsulClientConfiguration to reduce confusion.
  • Completed major rework of the Client class to remove unneeded type parameters from various internal calls
  • Added interfaces to all the endpoint classes so that test mocking is possible.
