The Metadata query function +executes an external query tool appropriate to the current workspace. + +Loading packages always returns the complete import graph "all the way down", +even if all you want is information about a single package, because the query +mechanisms of all the build systems we currently support ({go,vgo} list, and +blaze/bazel aspect-based query) cannot provide detailed information +about one package without visiting all its dependencies too, so there is +no additional asymptotic cost to providing transitive information. +(This property might not be true of a hypothetical 5th build system.) + +In calls to TypeCheck, all initial packages, and any package that +transitively depends on one of them, must be loaded from source. +Consider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from +source; D may be loaded from export data, and E may not be loaded at all +(though it's possible that D's export data mentions it, so a +types.Package may be created for it and exposed.) + +The old loader had a feature to suppress type-checking of function +bodies on a per-package basis, primarily intended to reduce the work of +obtaining type information for imported packages. Now that imports are +satisfied by export data, the optimization no longer seems necessary. + +Despite some early attempts, the old loader did not exploit export data, +instead always using the equivalent of WholeProgram mode. This was due +to the complexity of mixing source and export data packages (now +resolved by the upward traversal mentioned above), and because export data +files were nearly always missing or stale. Now that 'go build' supports +caching, all the underlying build systems can guarantee to produce +export data in a reasonable (amortized) time. + +Test "main" packages synthesized by the build system are now reported as +first-class packages, avoiding the need for clients (such as go/ssa) to +reinvent this generation logic. + +One way in which go/packages is simpler than the old loader is in its +treatment of in-package tests. In-package tests are packages that +consist of all the files of the library under test, plus the test files. +The old loader constructed in-package tests by a two-phase process of +mutation called "augmentation": first it would construct and type check +all the ordinary library packages and type-check the packages that +depend on them; then it would add more (test) files to the package and +type-check again. This two-phase approach had four major problems: +1) in processing the tests, the loader modified the library package, + leaving no way for a client application to see both the test + package and the library package; one would mutate into the other. +2) because test files can declare additional methods on types defined in + the library portion of the package, the dispatch of method calls in + the library portion was affected by the presence of the test files. + This should have been a clue that the packages were logically + different. +3) this model of "augmentation" assumed at most one in-package test + per library package, which is true of projects using 'go build', + but not other build systems. +4) because of the two-phase nature of test processing, all packages that + import the library package had to be processed before augmentation, + forcing a "one-shot" API and preventing the client from calling Load + in several times in sequence as is now possible in WholeProgram mode. + (TypeCheck mode has a similar one-shot restriction for a different reason.) + +Early drafts of this package supported "multi-shot" operation. +Although it allowed clients to make a sequence of calls (or concurrent +calls) to Load, building up the graph of Packages incrementally, +it was of marginal value: it complicated the API +(since it allowed some options to vary across calls but not others), +it complicated the implementation, +it cannot be made to work in Types mode, as explained above, +and it was less efficient than making one combined call (when this is possible). +Among the clients we have inspected, none made multiple calls to load +but could not be easily and satisfactorily modified to make only a single call. +However, applications changes may be required. +For example, the ssadump command loads the user-specified packages +and in addition the runtime package. It is tempting to simply append +"runtime" to the user-provided list, but that does not work if the user +specified an ad-hoc package such as [a.go b.go]. +Instead, ssadump no longer requests the runtime package, +but seeks it among the dependencies of the user-specified packages, +and emits an error if it is not found. + +Overlays: The Overlay field in the Config allows providing alternate contents +for Go source files, by providing a mapping from file path to contents. +go/packages will pull in new imports added in overlay files when go/packages +is run in LoadImports mode or greater. +Overlay support for the go list driver isn't complete yet: if the file doesn't +exist on disk, it will only be recognized in an overlay if it is a non-test file +and the package would be reported even without the overlay. + +Questions & Tasks + +- Add GOARCH/GOOS? + They are not portable concepts, but could be made portable. + Our goal has been to allow users to express themselves using the conventions + of the underlying build system: if the build system honors GOARCH + during a build and during a metadata query, then so should + applications built atop that query mechanism. + Conversely, if the target architecture of the build is determined by + command-line flags, the application can pass the relevant + flags through to the build system using a command such as: + myapp -query_flag="--cpu=amd64" -query_flag="--os=darwin" + However, this approach is low-level, unwieldy, and non-portable. + GOOS and GOARCH seem important enough to warrant a dedicated option. + +- How should we handle partial failures such as a mixture of good and + malformed patterns, existing and non-existent packages, successful and + failed builds, import failures, import cycles, and so on, in a call to + Load? + +- Support bazel, blaze, and go1.10 list, not just go1.11 list. + +- Handle (and test) various partial success cases, e.g. + a mixture of good packages and: + invalid patterns + nonexistent packages + empty packages + packages with malformed package or import declarations + unreadable files + import cycles + other parse errors + type errors + Make sure we record errors at the correct place in the graph. + +- Missing packages among initial arguments are not reported. + Return bogus packages for them, like golist does. + +- "undeclared name" errors (for example) are reported out of source file + order. I suspect this is due to the breadth-first resolution now used + by go/types. Is that a bug?

Go's thread scheduling model switches goroutines between OS threads based on OS thread load and whether the goroutine would block other goroutines. This can result in a goroutine switching network namespaces without notice and lead to errors in your code. + +### Namespace Switching +Switching namespaces with the `ns.Set()` method is not recommended without additional strategies to prevent unexpected namespace changes when your goroutines switch OS threads. + +Go provides the `runtime.LockOSThread()` function to ensure a specific goroutine executes on its current OS thread and prevents any other goroutine from running in that thread until the locked one exits. Careful usage of `LockOSThread()` and goroutines can provide good control over which network namespace a given goroutine executes in. + +For example, you cannot rely on the `ns.Set()` namespace being the current namespace after the `Set()` call unless you do two things. First, the goroutine calling `Set()` must have previously called `LockOSThread()`. Second, you must ensure `runtime.UnlockOSThread()` is not called somewhere in-between. You also cannot rely on the initial network namespace remaining the current network namespace if any other code in your program switches namespaces, unless you have already called `LockOSThread()` in that goroutine. Note that `LockOSThread()` prevents the Go scheduler from optimally scheduling goroutines for best performance, so `LockOSThread()` should only be used in small, isolated goroutines that release the lock quickly. + +### Do() The Recommended Thing +The `ns.Do()` method provides **partial** control over network namespaces for you by implementing these strategies. All code dependent on a particular network namespace (including the root namespace) should be wrapped in the `ns.Do()` method to ensure the correct namespace is selected for the duration of your code. For example: + +```go +err = targetNs.Do(func(hostNs ns.NetNS) error { + dummy := &netlink.Dummy{ + LinkAttrs: netlink.LinkAttrs{ + Name: "dummy0", + }, + } + return netlink.LinkAdd(dummy) +}) +``` + +Note this requirement to wrap every network call is very onerous - any libraries you call might call out to network services such as DNS, and all such calls need to be protected after you call `ns.Do()`. All goroutines spawned from within the `ns.Do` will not inherit the new namespace. The CNI plugins all exit very soon after calling `ns.Do()` which helps to minimize the problem. + +When a new thread is spawned in Linux, it inherits the namespace of its parent. In versions of go **prior to 1.10**, if the runtime spawns a new OS thread, it picks the parent randomly. If the chosen parent thread has been moved to a new namespace (even temporarily), the new OS thread will be permanently "stuck in the wrong namespace", and goroutines will non-deterministically switch namespaces as they are rescheduled. + +In short, **there was no safe way to change network namespaces, even temporarily, from within a long-lived, multithreaded Go process**. If you wish to do this, you must use go 1.10 or greater. + + +### Creating network namespaces +Earlier versions of this library managed namespace creation, but as CNI does not actually utilize this feature (and it was essentially unmaintained), it was removed. If you're writing a container runtime, you should implement namespace management yourself. However, there are some gotchas when doing so, especially around handling `/var/run/netns`. A reasonably correct reference implementation, borrowed from `rkt`, can be found in `pkg/testutils/netns_linux.go` if you're in need of a source of inspiration. + + +### Further Reading + - https://github.com/golang/go/wiki/LockOSThread + - http://morsmachine.dk/go-scheduler + - https://github.com/containernetworking/cni/issues/262 + - https://golang.org/pkg/runtime/ + - https://www.weave.works/blog/linux-namespaces-and-go-don-t-mix diff --git a/ecs-agent/vendor/github.com/containernetworking/plugins/pkg/ns/ns_linux.go b/ecs-agent/vendor/github.com/containernetworking/plugins/pkg/ns/ns_linux.go new file mode 100644 index 00000000000..3b745d4913f --- /dev/null +++ b/ecs-agent/vendor/github.com/containernetworking/plugins/pkg/ns/ns_linux.go @@ -0,0 +1,234 @@ +// Copyright 2015-2017 CNI authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package ns + +import ( + "fmt" + "os" + "runtime" + "sync" + "syscall" + + "golang.org/x/sys/unix" +) + +// Returns an object representing the current OS thread's network namespace +func GetCurrentNS() (NetNS, error) { + // Lock the thread in case other goroutine executes in it and changes its + // network namespace after getCurrentThreadNetNSPath(), otherwise it might + // return an unexpected network namespace. + runtime.LockOSThread() + defer runtime.UnlockOSThread() + return GetNS(getCurrentThreadNetNSPath()) +} + +func getCurrentThreadNetNSPath() string { + // /proc/self/ns/net returns the namespace of the main thread, not + // of whatever thread this goroutine is running on.

With gob, you could just send it. With goprotobuf, you need to make a parallel struct. +Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions. + + - nullable, if false, a field is generated without a pointer (see warning below). + - embed, if true, the field is generated as an embedded field. + - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128 + - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames. + - casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums. + - castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps. + - castvalue (beta), Changes the generated fieldtype for a map value.

This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields. + - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf.

It's +simply too hard to do in a way that won't break many people's projects, which is +the last thing you want from your Logging library (again...). + +This does not mean Logrus is dead. Logrus will continue to be maintained for +security, (backwards compatible) bug fixes, and performance (where we are +limited by the interface). + +I believe Logrus' biggest contribution is to have played a part in today's +widespread use of structured logging in Golang. There doesn't seem to be a +reason to do a major, breaking iteration into Logrus V2, since the fantastic Go +community has built those independently. Many fantastic alternatives have sprung +up. Logrus would look like those, had it been re-designed with what we know +about structured logging in Go today. Check out, for example, +[Zerolog][zerolog], [Zap][zap], and [Apex][apex]. + +[zerolog]: https://github.com/rs/zerolog +[zap]: https://github.com/uber-go/zap +[apex]: https://github.com/apex/log + +**Seeing weird case-sensitive problems?** It's in the past been possible to +import Logrus as both upper- and lower-case. Due to the Go package environment, +this caused issues in the community and we needed a standard. Some environments +experienced problems with the upper-case variant, so the lower-case was decided. +Everything using `logrus` will need to use the lower-case: +`github.com/sirupsen/logrus`. Any package that isn't, should be changed. + +To fix Glide, see [these +comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437). +For an in-depth explanation of the casing issue, see [this +comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276). + +Nicely color-coded in development (when a TTY is attached, otherwise just +plain text): + +![Colored](http://i.imgur.com/PY7qMwd.png) + +With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash +or Splunk: + +```json +{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the +ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"} + +{"level":"warning","msg":"The group's number increased tremendously!", +"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"} + +{"animal":"walrus","level":"info","msg":"A giant walrus appears!", +"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"} + +{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.", +"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"} + +{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true, +"time":"2014-03-10 19:57:38.562543128 -0400 EDT"} +``` + +With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not +attached, the output is compatible with the +[logfmt](http://godoc.org/github.com/kr/logfmt) format: + +```text +time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8 +time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10 +time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true +time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4 +time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009 +time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true +``` +To ensure this behaviour even if a TTY is attached, set your formatter as follows: + +```go + log.SetFormatter(&log.TextFormatter{ + DisableColors: true, + FullTimestamp: true, + }) +``` + +#### Logging Method Name + +If you wish to add the calling method as a field, instruct the logger via: +```go +log.SetReportCaller(true) +``` +This adds the caller as 'method' like so: + +```json +{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by", +"time":"2014-03-10 19:57:38.562543129 -0400 EDT"} +``` + +```text +time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin +``` +Note that this does add measurable overhead - the cost will depend on the version of Go, but is +between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your +environment via benchmarks: +``` +go test -bench=.*CallerTracing +``` + + +#### Case-sensitivity + +The organization's name was changed to lower-case--and this will not be changed +back. If you are getting import conflicts due to case sensitivity, please use +the lower-case import: `github.com/sirupsen/logrus`. + +#### Example + +The simplest way to use Logrus is simply the package-level exported logger: + +```go +package main + +import ( + log "github.com/sirupsen/logrus" +) + +func main() { + log.WithFields(log.Fields{ + "animal": "walrus", + }).Info("A walrus appears") +} +``` + +Note that it's completely api-compatible with the stdlib logger, so you can +replace your `log` imports everywhere with `log "github.com/sirupsen/logrus"` +and you'll now have the flexibility of Logrus. You can customize it all you +want: + +```go +package main + +import ( + "os" + log "github.com/sirupsen/logrus" +) + +func init() { + // Log as JSON instead of the default ASCII formatter. + log.SetFormatter(&log.JSONFormatter{}) + + // Output to stdout instead of the default stderr + // Can be any io.Writer, see below for File example + log.SetOutput(os.Stdout) + + // Only log the warning severity or above. + log.SetLevel(log.WarnLevel) +} + +func main() { + log.WithFields(log.Fields{ + "animal": "walrus", + "size": 10, + }).Info("A group of walrus emerges from the ocean") + + log.WithFields(log.Fields{ + "omg": true, + "number": 122, + }).Warn("The group's number increased tremendously!") + + log.WithFields(log.Fields{ + "omg": true, + "number": 100, + }).Fatal("The ice breaks!") + + // A common pattern is to re-use fields between logging statements by re-using + // the logrus.Entry returned from WithFields() + contextLogger := log.WithFields(log.Fields{ + "common": "this is a common field", + "other": "I also should be logged always", + }) + + contextLogger.Info("I'll be logged with common and other field") + contextLogger.Info("Me too") +} +``` + +For more advanced usage such as logging to multiple locations from the same +application, you can also create an instance of the `logrus` Logger: + +```go +package main + +import ( + "os" + "github.com/sirupsen/logrus" +) + +// Create a new instance of the logger. You can have any number of instances. +var log = logrus.New() + +func main() { + // The API for setting attributes is a little different than the package level + // exported logger. See Godoc. + log.Out = os.Stdout + + // You could set this to any `io.Writer` such as a file + // file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666) + // if err == nil { + // log.Out = file + // } else { + // log.Info("Failed to log to file, using default stderr") + // } + + log.WithFields(logrus.Fields{ + "animal": "walrus", + "size": 10, + }).Info("A group of walrus emerges from the ocean") +} +``` + +#### Fields + +Logrus encourages careful, structured logging through logging fields instead of +long, unparseable error messages. For example, instead of: `log.Fatalf("Failed +to send event %s to topic %s with key %d")`, you should log the much more +discoverable: + +```go +log.WithFields(log.Fields{ + "event": event, + "topic": topic, + "key": key, +}).Fatal("Failed to send event") +``` + +We've found this API forces you to think about logging in a way that produces +much more useful logging messages. We've been in countless situations where just +a single added field to a log statement that was already there would've saved us +hours. The `WithFields` call is optional. + +In general, with Logrus using any of the `printf`-family functions should be +seen as a hint you should add a field, however, you can still use the +`printf`-family functions with Logrus. + +#### Default Fields + +Often it's helpful to have fields _always_ attached to log statements in an +application or parts of one. For example, you may want to always log the +`request_id` and `user_ip` in the context of a request. Instead of writing +`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on +every line, you can create a `logrus.Entry` to pass around instead: + +```go +requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip}) +requestLogger.Info("something happened on that request") # will log request_id and user_ip +requestLogger.Warn("something not great happened") +``` + +#### Hooks + +You can add hooks for logging levels. For example to send errors to an exception +tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to +multiple places simultaneously, e.g. syslog. + +Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in +`init`: + +```go +import ( + log "github.com/sirupsen/logrus" + "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "airbrake" + logrus_syslog "github.com/sirupsen/logrus/hooks/syslog" + "log/syslog" +) + +func init() { + + // Use the Airbrake hook to report errors that have Error severity or above to + // an exception tracker. You can create custom hooks, see the Hooks section. + log.AddHook(airbrake.NewHook(123, "xyz", "production")) + + hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "") + if err != nil { + log.Error("Unable to connect to local syslog daemon") + } else { + log.AddHook(hook) + } +} +``` +Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md). + +A list of currently known service hooks can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks) + + +#### Level logging + +Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic. + +```go +log.Trace("Something very low level.") +log.Debug("Useful debugging information.") +log.Info("Something noteworthy happened!") +log.Warn("You should probably take a look at this.") +log.Error("Something failed but I'm not quitting.") +// Calls os.Exit(1) after logging +log.Fatal("Bye.") +// Calls panic() after logging +log.Panic("I'm bailing.") +``` + +You can set the logging level on a `Logger`, then it will only log entries with +that severity or anything above it: + +```go +// Will log anything that is info or above (warn, error, fatal, panic). Default. +log.SetLevel(log.InfoLevel) +``` + +It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose +environment if your application has that. + +#### Entries + +Besides the fields added with `WithField` or `WithFields` some fields are +automatically added to all logging events: + +1. `time`. The timestamp when the entry was created. +2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after + the `AddFields` call. E.g. `Failed to send event.` +3. `level`. The logging level. E.g. `info`. + +#### Environments + +Logrus has no notion of environment. + +If you wish for hooks and formatters to only be used in specific environments, +you should handle that yourself. For example, if your application has a global +variable `Environment`, which is a string representation of the environment you +could do: + +```go +import ( + log "github.com/sirupsen/logrus" +) + +func init() { + // do something here to set environment depending on an environment variable + // or command-line flag + if Environment == "production" { + log.SetFormatter(&log.JSONFormatter{}) + } else { + // The TextFormatter is default, you don't actually have to do this. + log.SetFormatter(&log.TextFormatter{}) + } +} +``` + +This configuration is how `logrus` was intended to be used, but JSON in +production is mostly only useful if you do log aggregation with tools like +Splunk or Logstash. + +#### Formatters + +The built-in logging formatters are: + +* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise + without colors. + * *Note:* to force colored output when there is no TTY, set the `ForceColors` + field to `true`. To force no colored output even if there is a TTY set the + `DisableColors` field to `true`. For Windows, see + [github.com/mattn/go-colorable](https://github.com/mattn/go-colorable). + * When colors are enabled, levels are truncated to 4 characters by default. To disable + truncation set the `DisableLevelTruncation` field to `true`. + * When outputting to a TTY, it's often helpful to visually scan down a column where all the levels are the same width. Setting the `PadLevelText` field to `true` enables this behavior, by adding padding to the level text. + * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter). +* `logrus.JSONFormatter`. Logs fields as JSON. + * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter). + +Third party logging formatters: + +* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine. +* [`GELF`](https://github.com/fabienm/go-logrus-formatters). Formats entries so they comply to Graylog's [GELF 1.1 specification](http://docs.graylog.org/en/2.4/pages/gelf.html). +* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events. +* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout. +* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the Power of Zalgo. +* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure. +* [`powerful-logrus-formatter`](https://github.com/zput/zxcTool). get fileName, log's line number and the latest function's name when print log; Sava log to files. +* [`caption-json-formatter`](https://github.com/nolleh/caption_json_formatter). logrus's message json formatter with human-readable caption added. + +You can define your formatter by implementing the `Formatter` interface, +requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a +`Fields` type (`map[string]interface{}`) with all your fields as well as the +default ones (see Entries section above): + +```go +type MyJSONFormatter struct { +} + +log.SetFormatter(new(MyJSONFormatter)) + +func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) { + // Note this doesn't include Time, Level and Message which are available on + // the Entry. Consult `godoc` on information about those fields or read the + // source of the official loggers. + serialized, err := json.Marshal(entry.Data) + if err != nil { + return nil, fmt.Errorf("Failed to marshal fields to JSON, %w", err) + } + return append(serialized, '\n'), nil +} +``` + +#### Logger as an `io.Writer` + +Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it. + +```go +w := logger.Writer() +defer w.Close() + +srv := http.Server{ + // create a stdlib log.Logger that writes to + // logrus.Logger. + ErrorLog: log.New(w, "", 0), +} +``` + +Each line written to that writer will be printed the usual way, using formatters +and hooks. The level for those entries is `info`. + +This means that we can override the standard library logger easily: + +```go +logger := logrus.New() +logger.Formatter = &logrus.JSONFormatter{} + +// Use logrus for standard log output +// Note that `log` here references stdlib's log +// Not logrus imported under the name `log`. +log.SetOutput(logger.Writer()) +``` + +#### Rotation + +Log rotation is not provided with Logrus. Log rotation should be done by an +external program (like `logrotate(8)`) that can compress and delete old log +entries. It should not be a feature of the application-level logger. + +#### Tools + +| Tool | Description | +| ---- | ----------- | +|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will be generated with different configs in different environments.| +|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper around Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) | + +#### Testing + +Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides: + +* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just adds the `test` hook +* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any): + +```go +import( + "github.com/sirupsen/logrus" + "github.com/sirupsen/logrus/hooks/test" + "github.com/stretchr/testify/assert" + "testing" +) + +func TestSomething(t*testing.T){ + logger, hook := test.NewNullLogger() + logger.Error("Helloerror") + + assert.Equal(t, 1, len(hook.Entries)) + assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level) + assert.Equal(t, "Helloerror", hook.LastEntry().Message) + + hook.Reset() + assert.Nil(t, hook.LastEntry()) +} +``` + +#### Fatal handlers + +Logrus can register one or more functions that will be called when any `fatal` +level message is logged. The registered handlers will be executed before +logrus performs an `os.Exit(1)`. This behavior may be helpful if callers need +to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted. + +``` +... +handler := func() { + // gracefully shutdown something... +} +logrus.RegisterExitHandler(handler) +... +``` + +#### Thread safety + +By default, Logger is protected by a mutex for concurrent writes. The mutex is held when calling hooks and writing logs. +If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking. + +Situation when locking is not needed includes: + +* You have no hooks registered, or hooks calling is already thread-safe. + +* Writing to logger.Out is already thread-safe, for example: + + 1) logger.Out is protected by locks. + + 2) logger.Out is an os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allows multi-thread/multi-process writing) + + (Refer to http://www.notthewizard.com/2014/06/17/are-files-appends-really-atomic/) diff --git a/ecs-agent/vendor/github.com/sirupsen/logrus/alt_exit.go b/ecs-agent/vendor/github.com/sirupsen/logrus/alt_exit.go new file mode 100644 index 00000000000..8fd189e1cca --- /dev/null +++ b/ecs-agent/vendor/github.com/sirupsen/logrus/alt_exit.go @@ -0,0 +1,76 @@ +package logrus + +// The following code was sourced and modified from the +// https://github.com/tebeka/atexit package governed by the following license: +// +// Copyright (c) 2012 Miki Tebeka . +// +// 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.

OpenCensus allows +you to instrument your services and collect diagnostics data all +through your services end-to-end. + +## Tags + +Tags represent propagated key-value pairs. They are propagated using `context.Context` +in the same process or can be encoded to be transmitted on the wire. Usually, this will +be handled by an integration plugin, e.g. `ocgrpc.ServerHandler` and `ocgrpc.ClientHandler` +for gRPC. + +Package `tag` allows adding or modifying tags in the current context. + +[embedmd]:# (internal/readme/tags.go new) +```go +ctx, err := tag.New(ctx, + tag.Insert(osKey, "macOS-10.12.5"), + tag.Upsert(userIDKey, "cde36753ed"), +) +if err != nil { + log.Fatal(err) +} +``` + +## Stats + +OpenCensus is a low-overhead framework even if instrumentation is always enabled. +In order to be so, it is optimized to make recording of data points fast +and separate from the data aggregation. + +OpenCensus stats collection happens in two stages: + +* Definition of measures and recording of data points +* Definition of views and aggregation of the recorded data + +### Recording + +Measurements are data points associated with a measure. +Recording implicitly tags the set of Measurements with the tags from the +provided context: + +[embedmd]:# (internal/readme/stats.go record) +```go +stats.Record(ctx, videoSize.M(102478)) +``` + +### Views + +Views are how Measures are aggregated. You can think of them as queries over the +set of recorded data points (measurements). + +Views have two parts: the tags to group by and the aggregation type used. + +Currently three types of aggregations are supported: +* CountAggregation is used to count the number of times a sample was recorded. +* DistributionAggregation is used to provide a histogram of the values of the samples. +* SumAggregation is used to sum up all sample values. + +[embedmd]:# (internal/readme/stats.go aggs) +```go +distAgg := view.Distribution(1<<32, 2<<32, 3<<32) +countAgg := view.Count() +sumAgg := view.Sum() +``` + +Here we create a view with the DistributionAggregation over our measure. + +[embedmd]:# (internal/readme/stats.go view) +```go +if err := view.Register(&view.View{ + Name: "example.com/video_size_distribution", + Description: "distribution of processed video size over time", + Measure: videoSize, + Aggregation: view.Distribution(1<<32, 2<<32, 3<<32), +}); err != nil { + log.Fatalf("Failed to register view: %v", err) +} +``` + +Register begins collecting data for the view. Registered views' data will be +exported via the registered exporters. + +## Traces + +A distributed trace tracks the progression of a single user request as +it is handled by the services and processes that make up an application. +Each step is called a span in the trace. Spans include metadata about the step, +including especially the time spent in the step, called the span’s latency. + +Below you see a trace and several spans underneath it. + +![Traces and spans](https://i.imgur.com/7hZwRVj.png) + +### Spans + +Span is the unit step in a trace. Each span has a name, latency, status and +additional metadata. + +Below we are starting a span for a cache read and ending it +when we are done: + +[embedmd]:# (internal/readme/trace.go startend) +```go +ctx, span := trace.StartSpan(ctx, "cache.Get") +defer span.End() + +// Do work to get from cache. +``` + +### Propagation + +Spans can have parents or can be root spans if they don't have any parents. +The current span is propagated in-process and across the network to allow associating +new child spans with the parent. + +In the same process, `context.Context` is used to propagate spans. +`trace.StartSpan` creates a new span as a root if the current context +doesn't contain a span. Or, it creates a child of the span that is +already in current context. The returned context can be used to keep +propagating the newly created span in the current context. + +[embedmd]:# (internal/readme/trace.go startend) +```go +ctx, span := trace.StartSpan(ctx, "cache.Get") +defer span.End() + +// Do work to get from cache. +``` + +Across the network, OpenCensus provides different propagation +methods for different protocols. + +* gRPC integrations use the OpenCensus' [binary propagation format](https://godoc.org/go.opencensus.io/trace/propagation). +* HTTP integrations use Zipkin's [B3](https://github.com/openzipkin/b3-propagation) + by default but can be configured to use a custom propagation method by setting another + [propagation.HTTPFormat](https://godoc.org/go.opencensus.io/trace/propagation#HTTPFormat). + +## Execution Tracer + +With Go 1.11, OpenCensus Go will support integration with the Go execution tracer. +See [Debugging Latency in Go](https://medium.com/observability/debugging-latency-in-go-1-11-9f97a7910d68) +for an example of their mutual use. + +## Profiles + +OpenCensus tags can be applied as profiler labels +for users who are on Go 1.9 and above. + +[embedmd]:# (internal/readme/tags.go profiler) +```go +ctx, err = tag.New(ctx, + tag.Insert(osKey, "macOS-10.12.5"), + tag.Insert(userIDKey, "fff0989878"), +) +if err != nil { + log.Fatal(err) +} +tag.Do(ctx, func(ctx context.Context) { + // Do work. + // When profiling is on, samples will be + // recorded with the key/values from the tag map. +}) +``` + +A screenshot of the CPU profile from the program above: + +![CPU profile](https://i.imgur.com/jBKjlkw.png) + +## Deprecation Policy + +Before version 1.0.0, the following deprecation policy will be observed: + +No backwards-incompatible changes will be made except for the removal of symbols that have +been marked as *Deprecated* for at least one minor release (e.g. 0.9.0 to 0.10.0).
