The following rules describe how APIs/constants are mapped from C +// to Go +// +// For structs, the 'vir' prefix and 'Ptr' suffix are removed from the name. +// e.g. virConnectPtr in C becomes 'Connect' in Go. +// +// For structs which are reference counted at the C level, it is neccessary to +// explicitly release the reference at the Go level. e.g. if a Go method returns +// a '* Domain' struct, it is neccessary to call 'Free' on this when no longer +// required. The use of 'defer' is recommended for this purpose +// +// dom, err := conn.LookupDomainByName("myguest") +// if err != nil { +// ... +// } +// defer dom.Free() +// +// If multiple goroutines are using the same libvirt object struct, it may +// not be possible to determine which goroutine should call 'Free'. In such +// scenarios each new goroutine should call 'Ref' to obtain a private reference +// on the underlying C struct. All goroutines can call 'Free' unconditionally +// with the final one causing the release of the C object. +// +// For methods, the 'vir' prefix and object name prefix are remove from the name. +// The C functions become methods with an object receiver. e.g. +// 'virDomainScreenshot' in C becomes 'Screenshot' with a 'Domain *' receiver. +// +// For methods which accept a 'unsigned int flags' parameter in the C level, +// the corresponding Go parameter will be a named type corresponding to the +// C enum that defines the valid flags. For example, the ListAllDomains +// method takes a 'flags ConnectListAllDomainsFlags' parameter. If there are +// not currently any flags defined for a method in the C API, then the Go +// method parameter will be declared as a "flags uint32". Callers should always +// pass the literal integer value 0 for such parameters, without forcing any +// specific type. This will allow compatibility with future updates to the +// libvirt-go binding which may replace the 'uint32' type with a enum type +// at a later date. +// +// For enums, the VIR_ prefix is removed from the name. The enums get a dedicated +// type defined in Go. e.g. the VIR_NODE_SUSPEND_TARGET_MEM enum constant in C, +// becomes NODE_SUSPEND_TARGET_MEM with a type of NodeSuspendTarget. +// +// Methods accepting or returning virTypedParameter arrays in C will map the +// parameters into a Go struct. The struct will contain two fields for each +// possible parameter. One boolean field with a suffix of 'Set' indicates whether +// the parameter has a value set, and the other custom typed field provides the +// parameter value. This makes it possible to distinguish a parameter with a +// default value of '0' from a parameter which is 0 because it isn't supported by +// the hypervisor. If the C API defines additional typed parameters, then the +// corresponding Go struct will be extended to have further fields. +// e.g. the GetMemoryStats method in Go (which is backed by +// virNodeGetMemoryStats in C) will return a NodeMemoryStats struct containing +// the typed parameter values. +// +// stats, err := conn.GetMemoryParameters() +// if err != nil { +// .... +// } +// if stats.TotalSet { +// fmt.Printf("Total memory: %d KB", stats.Total) +// } +// +// Every method that can fail will include an 'error' object as the last return +// value. This will be an instance of the Error struct if an error occurred. To +// check for specific libvirt error codes, it is neccessary to cast the error. +// +// err := storage_vol.Wipe(0) +// if err != nil { +// lverr, ok := err.(libvirt.Error) +// if ok && lverr.Code == libvirt.ERR_NO_SUPPORT { +// fmt.Println("Wiping storage volumes is not supported"); +// } else { +// fmt.Println("Error wiping storage volume: %s", err) +// } +// } +// +// Example usage +// +// To connect to libvirt +// +// import ( +// libvirt "github.com/libvirt/libvirt-go" +// ) +// conn, err := libvirt.NewConnect("qemu:///system") +// if err != nil { +// ... +// } +// defer conn.Close() +// +// doms, err := conn.ListAllDomains(libvirt.CONNECT_LIST_DOMAINS_ACTIVE) +// if err != nil { +// ... +// } +// +// fmt.Printf("%d running domains:\n", len(doms)) +// for _, dom := range doms { +// name, err := dom.GetName() +// if err == nil { +// fmt.Printf(" %s\n", name) +// } +// dom.Free() +// } +// +package libvirt diff --git a/src/dma/vendor/github.com/libvirt/libvirt-go/domain.go b/src/dma/vendor/github.com/libvirt/libvirt-go/domain.go new file mode 100644 index 00000000..3a3ef5b7 --- /dev/null +++ b/src/dma/vendor/github.com/libvirt/libvirt-go/domain.go @@ -0,0 +1,4766 @@ +/* + * This file is part of the libvirt-go project + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

They will be discussed on [Github +issues](https://github.com/streadway/amqp/issues) along with any bugs or +enhancements. + +## Supported Go Versions + +This library supports two most recent Go release series, currently 1.8 and 1.9. + + +## Supported RabbitMQ Versions + +This project supports RabbitMQ versions starting with `2.0` but primarily tested +against reasonably recent `3.x` releases. Some features and behaviours may be +server version-specific. + +## Goals + +Provide a functional interface that closely represents the AMQP 0.9.1 model +targeted to RabbitMQ as a server. This includes the minimum necessary to +interact the semantics of the protocol. + +## Non-goals + +Things not intended to be supported. + + * Auto reconnect and re-synchronization of client and server topologies. + * Reconnection would require understanding the error paths when the + topology cannot be declared on reconnect. This would require a new set + of types and code paths that are best suited at the call-site of this + package. AMQP has a dynamic topology that needs all peers to agree. If + this doesn't happen, the behavior is undefined. Instead of producing a + possible interface with undefined behavior, this package is designed to + be simple for the caller to implement the necessary connection-time + topology declaration so that reconnection is trivial and encapsulated in + the caller's application code. + * AMQP Protocol negotiation for forward or backward compatibility. + * 0.9.1 is stable and widely deployed. Versions 0.10 and 1.0 are divergent + specifications that change the semantics and wire format of the protocol. + We will accept patches for other protocol support but have no plans for + implementation ourselves. + * Anything other than PLAIN and EXTERNAL authentication mechanisms. + * Keeping the mechanisms interface modular makes it possible to extend + outside of this package. If other mechanisms prove to be popular, then + we would accept patches to include them in this package. + +## Usage + +See the 'examples' subdirectory for simple producers and consumers executables. +If you have a use-case in mind which isn't well-represented by the examples, +please file an issue. + +## Documentation + +Use [Godoc documentation](http://godoc.org/github.com/streadway/amqp) for +reference and usage. + +[RabbitMQ tutorials in +Go](https://github.com/rabbitmq/rabbitmq-tutorials/tree/master/go) are also +available. + +## Contributing + +Pull requests are very much welcomed. Create your pull request on a non-master +branch, make sure a test or example is included that covers your change and +your commits represent coherent changes that include a reason for the change. + +To run the integration tests, make sure you have RabbitMQ running on any host, +export the environment variable `AMQP_URL=amqp://host/` and run `go test -tags +integration`.

AMQP is programmable, meaning that both the producers and +consumers agree on the configuration of the broker, instead requiring an +operator or system configuration that declares the logical topology in the +broker. The routing between producers and consumer queues is via Bindings. +These bindings form the logical topology of the broker. + +In this library, a message sent from publisher is called a "Publishing" and a +message received to a consumer is called a "Delivery". The fields of +Publishings and Deliveries are close but not exact mappings to the underlying +wire format to maintain stronger types. Many other libraries will combine +message properties with message headers. In this library, the message well +known properties are strongly typed fields on the Publishings and Deliveries, +whereas the user defined headers are in the Headers field. + +The method naming closely matches the protocol's method name with positional +parameters mapping to named protocol message fields. The motivation here is to +present a comprehensive view over all possible interactions with the server. + +Generally, methods that map to protocol methods of the "basic" class will be +elided in this interface, and "select" methods of various channel mode selectors +will be elided for example Channel.Confirm and Channel.Tx. + +The library is intentionally designed to be synchronous, where responses for +each protocol message are required to be received in an RPC manner. Some +methods have a noWait parameter like Channel.QueueDeclare, and some methods are +asynchronous like Channel.Publish. The error values should still be checked for +these methods as they will indicate IO failures like when the underlying +connection closes. + +Asynchronous Events + +Clients of this library may be interested in receiving some of the protocol +messages other than Deliveries like basic.ack methods while a channel is in +confirm mode. + +The Notify* methods with Connection and Channel receivers model the pattern of +asynchronous events like closes due to exceptions, or messages that are sent out +of band from an RPC call like basic.ack or basic.flow. + +Any asynchronous events, including Deliveries and Publishings must always have +a receiver until the corresponding chans are closed. Without asynchronous +receivers, the sychronous methods will block. + +Use Case + +It's important as a client to an AMQP topology to ensure the state of the +broker matches your expectations. For both publish and consume use cases, +make sure you declare the queues, exchanges and bindings you expect to exist +prior to calling Channel.Publish or Channel.Consume. + + // Connections start with amqp.Dial() typically from a command line argument + // or environment variable. + connection, err := amqp.Dial(os.Getenv("AMQP_URL")) + + // To cleanly shutdown by flushing kernel buffers, make sure to close and + // wait for the response. + defer connection.Close() + + // Most operations happen on a channel. If any error is returned on a + // channel, the channel will no longer be valid, throw it away and try with + // a different channel. If you use many channels, it's useful for the + // server to + channel, err := connection.Channel() + + // Declare your topology here, if it doesn't exist, it will be created, if + // it existed already and is not what you expect, then that's considered an + // error. + + // Use your connection on this topology with either Publish or Consume, or + // inspect your queues with QueueInspect. It's unwise to mix Publish and + // Consume to let TCP do its job well. + +SSL/TLS - Secure connections + +When Dial encounters an amqps:// scheme, it will use the zero value of a +tls.Config. This will only perform server certificate and host verification. + +Use DialTLS when you wish to provide a client certificate (recommended), +include a private certificate authority's certificate in the cert chain for +server validity, or run insecure by not verifying the server certificate dial +your own connection. DialTLS will use the provided tls.Config when it +encounters an amqps:// scheme and will dial a plain connection when it +encounters an amqp:// scheme. + +SSL/TLS in RabbitMQ is documented here: http://www.rabbitmq.com/ssl.html + +*/ +package amqp diff --git a/src/dma/vendor/github.com/streadway/amqp/fuzz.go b/src/dma/vendor/github.com/streadway/amqp/fuzz.go new file mode 100644 index 00000000..16e626ce --- /dev/null +++ b/src/dma/vendor/github.com/streadway/amqp/fuzz.go @@ -0,0 +1,17 @@ +// +build gofuzz + +package amqp + +import "bytes" + +func Fuzz(data []byte) int { + r := reader{bytes.NewReader(data)} + frame, err := r.ReadFrame() + if err != nil { + if frame != nil { + panic("frame is not nil") + } + return 0 + } + return 1 +} diff --git a/src/dma/vendor/github.com/streadway/amqp/gen.sh b/src/dma/vendor/github.com/streadway/amqp/gen.sh new file mode 100755 index 00000000..d46e19bd --- /dev/null +++ b/src/dma/vendor/github.com/streadway/amqp/gen.sh @@ -0,0 +1,2 @@ +#!/bin/sh +go run spec/gen.go < spec/amqp0-9-1.stripped.extended.xml | gofmt > spec091.go diff --git a/src/dma/vendor/github.com/streadway/amqp/pre-commit b/src/dma/vendor/github.com/streadway/amqp/pre-commit new file mode 100755 index 00000000..7607f467 --- /dev/null +++ b/src/dma/vendor/github.com/streadway/amqp/pre-commit @@ -0,0 +1,29 @@ +#!/bin/sh + +GOFMT_FILES=$(gofmt -l .) +if [ -n "${GOFMT_FILES}" ]; then + printf >&2 'gofmt failed for the following files:\n%s\n\nplease run "gofmt -w ." on your changes before committing.\n' "${GOFMT_FILES}" + exit 1 +fi + +GOLINT_ERRORS=$(golint ./... | grep -v "Id should be") +if [ -n "${GOLINT_ERRORS}" ]; then + printf >&2 'golint failed for the following reasons:\n%s\n\nplease run 'golint ./...' on your changes before committing.\n' "${GOLINT_ERRORS}" + exit 1 +fi + +GOVET_ERRORS=$(go tool vet *.go 2>&1) +if [ -n "${GOVET_ERRORS}" ]; then + printf >&2 'go vet failed for the following reasons:\n%s\n\nplease run "go tool vet *.go" on your changes before committing.\n' "${GOVET_ERRORS}" + exit 1 +fi + +if [ -z "${NOTEST}" ]; then + printf >&2 'Running short tests...\n' + env AMQP_URL= go test -short -v | egrep 'PASS|ok' + + if [ $? -ne 0 ]; then + printf >&2 'go test failed, please fix before committing.\n' + exit 1 + fi +fi diff --git a/src/dma/vendor/github.com/streadway/amqp/read.go b/src/dma/vendor/github.com/streadway/amqp/read.go new file mode 100644 index 00000000..3aa0b338 --- /dev/null +++ b/src/dma/vendor/github.com/streadway/amqp/read.go @@ -0,0 +1,456 @@ +// Copyright (c) 2012, Sean Treadway, SoundCloud Ltd. +// Use of this source code is governed by a BSD-style +// license that can be found in the LICENSE file. +// Source code and contact info at http://github.com/streadway/amqp + +package amqp + +import ( + "bytes" + "encoding/binary" + "errors" + "io" + "time" +) + +/* +Reads a frame from an input stream and returns an interface that can be cast into +one of the following: + + methodFrame + PropertiesFrame + bodyFrame + heartbeatFrame + +2.3.5 frame Details + +All frames consist of a header (7 octets), a payload of arbitrary size, and a +'frame-end' octet that detects malformed frames: + + 0 1 3 7 size+7 size+8 + +------+---------+-------------+ +------------+ +-----------+ + | type | channel | size | | payload | | frame-end | + +------+---------+-------------+ +------------+ +-----------+ + octet short long size octets octet + +To read a frame, we: + 1.
