Changes Between 2.11.0 and 2.12.0 (unreleased)

No changes yet.

Changes Between 2.10.0 and 2.11.0 (Sep 16, 2021)

This release contains minor breaking public API changes.

Avoid returning empty queue and exchange properties

struct values in ExportedDefinitions, QueueInfo, and ExchangeInfo have all been changed to pointers. This is to avoid having the empty struct values returned when exporting definitions and listing queues and exchanges.

Updated ExportedDefinitions, ExchangeInfo and QueueInfo.

Contributed by @mkuratczyk.

PRs: #208 and #209

Support for a special returned value of Queue and Exchange AutoDelete

QueueInfo and ExchangeInfo now use a special type for AutoDelete because returned value from RabbitMQ server could be a boolean or a string value "undefined".

// AutoDelete is a boolean but RabbitMQ may return the string "undefined"
type AutoDelete bool

// ExchangeInfo represents and exchange and its properties.
type ExchangeInfo struct {
	Name       string                 `json:"name"`
	Vhost      string                 `json:"vhost,omitempty"`
	Type       string                 `json:"type"`
	Durable    bool                   `json:"durable"`
	AutoDelete AutoDelete             `json:"auto_delete"`
...
}

// QueueInfo represents a queue, its properties and key metrics.
type QueueInfo struct {
	// Queue name
	Name string `json:"name"`
	// Queue type
	Type string `json:"type"`
	// Virtual host this queue belongs to
	Vhost string `json:"vhost,omitempty"`
	// Is this queue auto-deleted?
	AutoDelete AutoDelete `json:"auto_delete"`
         ...
}

Changes Between 2.9.0 and 2.10.0 (Jun 3, 2021)

This release contains very minor breaking public API changes.

ShovelDefinition.SourceDeleteAfter Type Now Matches That of ShovelDefinition.DeleteAfter

ShovelDefinition.SourceDeleteAfter type has changed to match that of ShovelDefinition.DeleteAfter.

GitHub issue: #197

Changes Between 2.8.0 and 2.9.0 (Jun 2, 2021)

This release contains minor breaking public API changes.

Support for Lists of Federation Upstream URIs

Federation definition now uses a dedicated type, URISet, to represent a set of URIs that will be tried sequentially until the link can successfully connect and authenticate:

def1 := FederationDefinition{
            Uri: URISet{"amqp://hostname/%2f"},
        }

URISet has now replaced ShovelURISet:

sDef := ShovelDefinition{
            SourceURI:         URISet([]string{"amqp://127.0.0.1/%2f"}),
            SourceQueue:       "mySourceQueue",
            DestinationURI:    ShovelURISet([]string{"amqp://host1/%2f"}),
            DestinationQueue:  "myDestQueue",
            AddForwardHeaders: true,
            AckMode:           "on-confirm",
            DeleteAfter:       "never",
        }

Changes Between 2.7.0 and 2.8.0 (Apr 12, 2021)

Global Runtime Parameters

The library now supports global runtime parameters:

// list all global parameters
params, err := rmqc.ListGlobalParameters()
// => []GlobalRuntimeParameter, error
// get a global parameter
p, err := rmqc.GetGlobalParameter("name")
// => *GlobalRuntimeParameter, error
// declare or update a global parameter
resp, err := rmqc.PutGlobalParameter("name", map[string]interface{
    endpoints: "amqp://server-name",
})
// => *http.Response, error
// delete a global parameter
resp, err := rmqc.DeleteGlobalParameter("name")
// => *http.Response, error

GitHub issue: #180

Changes Between 2.6.0 and 2.7.0 (Mar 30, 2021)

This release contains minor breaking public API changes and targets RabbitMQ 3.8.x (the only supported version at the time of writing) exclusively.

Support for Modern Health Check Endpoints

The client now supports modern health check endpoints (same checks as provided by rabbitmq-diagnostics):

import (
       "github.com/michaelklishin/rabbit-hole/v2"
)

rmqc, _ = NewClient("http://127.0.0.1:15672", "username", "$3KrEƮ")

res1, err1 := rmqc.HealthCheckAlarms()

res2, err2 := rmqc.HealthCheckLocalAlarms()

res3, err3 := rmqc.HealthCheckCertificateExpiration(1, DAYS)

res4, err4 := rmqc.HealthCheckPortListener(5672)

res5, err5 := rmqc.HealthCheckProtocolListener(AMQP091)

res6, err6 := rmqc.HealthCheckVirtualHosts()

res7, err7 := rmqc.HealthCheckNodeIsMirrorSyncCritical()

res8, err8 := rmqc.HealthCheckNodeIsQuorumCritical()

Contributed by Martin @mkrueger-sabio Krueger.

GitHub issue: #173

Support for Inspecting Shovel Status

ListShovelStatus is a new function that returns a list of Shovel status reports for a virtual host:

res, err := rmqc.ListShovelStatus("a-virtual-host")

Contributed by Martin @mkrueger-sabio Krueger.

GitHub issue: #178

Support for Lists of Shovel URIs

Shovel definition now uses a dedicated type, ShovelURISet, to represent a set of URIs that will be tried sequentially until the Shovel can successfully connect and authenticate:

sDef := ShovelDefinition{
            SourceURI:         ShovelURISet([]string{"amqp://host2/%2f", "amqp://host3/%2f"}),
            SourceQueue:       "mySourceQueue",
            DestinationURI:    ShovelURISet([]string{"amqp://host1/%2f"}),
            DestinationQueue:  "myDestQueue",
            AddForwardHeaders: true,
            AckMode:           "on-confirm",
            DeleteAfter:       "never",
        }

Source and destination URI sets are only supported by the Shovel plugin in RabbitMQ 3.8.x.

Originally suggested by @pathcl in #172.
