It's harder +to appreciate the absence of bugs, the slow but steady improvement in stability, +or the reliability of a release process. But those things distinguish a good +project from a great one. + +## Reviewers + +A reviewer is a core role within the project. +They share in reviewing issues and pull requests and their LGTM counts towards the +required LGTM count to merge a code change into the project. + +Reviewers are part of the organization but do not have write access. +Becoming a reviewer is a core aspect in the journey to becoming a maintainer. + +## Adding maintainers + +Maintainers are first and foremost contributors that have shown they are +committed to the long term success of a project. Contributors wanting to become +maintainers are expected to be deeply involved in contributing code, pull +request review, and triage of issues in the project for more than three months. + +Just contributing does not make you a maintainer, it is about building trust +with the current maintainers of the project and being a person that they can +depend on and trust to make decisions in the best interest of the project. + +Periodically, the existing maintainers curate a list of contributors that have +shown regular activity on the project over the prior months. From this list, +maintainer candidates are selected and proposed in a pull request or a +maintainers communication channel. + +After a candidate has been announced to the maintainers, the existing +maintainers are given five business days to discuss the candidate, raise +objections and cast their vote. Votes may take place on the communication +channel or via pull request comment. Candidates must be approved by at least 66% +of the current maintainers by adding their vote on the mailing list. The +reviewer role has the same process but only requires 33% of current maintainers. +Only maintainers of the repository that the candidate is proposed for are +allowed to vote. + +If a candidate is approved, a maintainer will contact the candidate to invite +the candidate to open a pull request that adds the contributor to the +MAINTAINERS file. The voting process may take place inside a pull request if a +maintainer has already discussed the candidacy with the candidate and a +maintainer is willing to be a sponsor by opening the pull request. The candidate +becomes a maintainer once the pull request is merged. + +## Stepping down policy + +Life priorities, interests, and passions can change. If you're a maintainer but +feel you must remove yourself from the list, inform other maintainers that you +intend to step down, and if possible, help find someone to pick up your work. +At the very least, ensure your work can be continued where you left off. + +After you've informed other maintainers, create a pull request to remove +yourself from the MAINTAINERS file. + +## Removal of inactive maintainers + +Similar to the procedure for adding new maintainers, existing maintainers can +be removed from the list if they do not show significant activity on the +project. Periodically, the maintainers review the list of maintainers and their +activity over the last three months. + +If a maintainer has shown insufficient activity over this period, a neutral +person will contact the maintainer to ask if they want to continue being +a maintainer. If the maintainer decides to step down as a maintainer, they +open a pull request to be removed from the MAINTAINERS file. + +If the maintainer wants to remain a maintainer, but is unable to perform the +required duties they can be removed with a vote of at least 66% of the current +maintainers. In this case, maintainers should first propose the change to +maintainers via the maintainers communication channel, then open a pull request +for voting. The voting period is five business days. The voting pull request +should not come as a surpise to any maintainer and any discussion related to +performance must not be discussed on the pull request. + +## How are decisions made? + +Docker distribution is an open-source project with an open design philosophy. +This means that the repository is the source of truth for EVERY aspect of the +project, including its philosophy, design, road map, and APIs. *If it's part of +the project, it's in the repo. If it's in the repo, it's part of the project.* + +As a result, all decisions can be expressed as changes to the repository. An +implementation change is a change to the source code. An API change is a change +to the API specification. A philosophy change is a change to the philosophy +manifesto, and so on. + +All decisions affecting distribution, big and small, follow the same 3 steps: + +* Step 1: Open a pull request. Anyone can do this. + +* Step 2: Discuss the pull request. Anyone can do this. + +* Step 3: Merge or refuse the pull request. Who does this depends on the nature +of the pull request and which areas of the project it affects. + +## Helping contributors with the DCO + +The [DCO or `Sign your work`](./CONTRIBUTING.md#sign-your-work) +requirement is not intended as a roadblock or speed bump. + +Some contributors are not as familiar with `git`, or have used a web +based editor, and thus asking them to `git commit --amend -s` is not the best +way forward. + +In this case, maintainers can update the commits based on clause (c) of the DCO. +The most trivial way for a contributor to allow the maintainer to do this, is to +add a DCO signature in a pull requests's comment, or a maintainer can simply +note that the change is sufficiently trivial that it does not substantially +change the existing contribution - i.e., a spelling change. + +When you add someone's DCO, please also add your own to keep a log. + +## I'm a maintainer. Should I make pull requests too? + +Yes. Nobody should ever push to master directly. All changes should be +made through a pull request. + +## Conflict Resolution + +If you have a technical dispute that you feel has reached an impasse with a +subset of the community, any contributor may open an issue, specifically +calling for a resolution vote of the current core maintainers to resolve the +dispute. The same voting quorums required (2/3) for adding and removing +maintainers will apply to conflict resolution. diff --git a/vendor/github.com/distribution/reference/LICENSE b/vendor/github.com/distribution/reference/LICENSE new file mode 100644 index 000000000..e06d20818 --- /dev/null +++ b/vendor/github.com/distribution/reference/LICENSE @@ -0,0 +1,202 @@ +Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

Unfortunately everything I've seen so far has a high chance of +breaking your application. + +The main problem is that a `http.ResponseWriter` often implements additional +interfaces such as `http.Flusher`, `http.CloseNotifier`, `http.Hijacker`, `http.Pusher`, and +`io.ReaderFrom`. So the naive approach of just wrapping `http.ResponseWriter` +in your own struct that also implements the `http.ResponseWriter` interface +will hide the additional interfaces mentioned above. This has a high change of +introducing subtle bugs into any non-trivial application. + +Another approach I've seen people take is to return a struct that implements +all of the interfaces above. However, that's also problematic, because it's +difficult to fake some of these interfaces behaviors when the underlying +`http.ResponseWriter` doesn't have an implementation. It's also dangerous, +because an application may choose to operate differently, merely because it +detects the presence of these additional interfaces. + +This package solves this problem by checking which additional interfaces a +`http.ResponseWriter` implements, returning a wrapped version implementing the +exact same set of interfaces. + +Additionally this package properly handles edge cases such as `WriteHeader` not +being called, or called more than once, as well as concurrent calls to +`http.ResponseWriter` methods, and even calls happening after the wrapped +`ServeHTTP` has already returned. + +Unfortunately this package is not perfect either. It's possible that it is +still missing some interfaces provided by the go core (let me know if you find +one), and it won't work for applications adding their own interfaces into the +mix. You can however use `httpsnoop.Unwrap(w)` to access the underlying +`http.ResponseWriter` and type-assert the result to its other interfaces. + +However, hopefully the explanation above has sufficiently scared you of rolling +your own solution to this problem. httpsnoop may still break your application, +but at least it tries to avoid it as much as possible. + +Anyway, the real problem here is that smuggling additional interfaces inside +`http.ResponseWriter` is a problematic design choice, but it probably goes as +deep as the Go language specification itself. But that's okay, I still prefer +Go over the alternatives ;). + +## Performance + +``` +BenchmarkBaseline-8 20000 94912 ns/op +BenchmarkCaptureMetrics-8 20000 95461 ns/op +``` + +As you can see, using `CaptureMetrics` on a vanilla http.Handler introduces an +overhead of ~500 ns per http request on my machine.

You + can just send PRs, but they may end up being rejected for one reason or the + other. -* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues). -* Please indicate the platform you are using fsnotify on. -* A code example to reproduce the problem is appreciated. +- fsnotify is a cross-platform library, and changes must work reasonably well on + all supported platforms. -## Pull Requests +- Changes will need to be compatible; old code should still compile, and the + runtime behaviour can't change in ways that are likely to lead to problems for + users. -### Contributor License Agreement +Testing +------- +Just `go test ./...` runs all the tests; the CI runs this on all supported +platforms. Testing different platforms locally can be done with something like +[goon] or [Vagrant], but this isn't super-easy to set up at the moment. -fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual). +Use the `-short` flag to make the "stress test" run faster. -Please indicate that you have signed the CLA in your pull request. -### How fsnotify is Developed - -* Development is done on feature branches. -* Tests are run on BSD, Linux, macOS and Windows. -* Pull requests are reviewed and [applied to master][am] using [hub][]. - * Maintainers may modify or squash commits rather than asking contributors to. -* To issue a new release, the maintainers will: - * Update the CHANGELOG - * Tag a version, which will become available through gopkg.in. - -### How to Fork - -For smooth sailing, always use the original import path. Installing with `go get` makes this easy. - -1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`) -2. Create your feature branch (`git checkout -b my-new-feature`) -3. Ensure everything works and the tests pass (see below) -4. Commit your changes (`git commit -am 'Add some feature'`) - -Contribute upstream: - -1. Fork fsnotify on GitHub -2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`) -3. Push to the branch (`git push fork my-new-feature`) -4. Create a new Pull Request on GitHub - -This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/). - -### Testing - -fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows. - -Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. - -To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. - -* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) -* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. -* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) -* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`. -* When you're done, you will want to halt or destroy the Vagrant boxes. - -Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory. - -Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads). - -### Maintainers - -Help maintaining fsnotify is welcome. To be a maintainer: - -* Submit a pull request and sign the CLA as above. -* You must be able to run the test suite on Mac, Windows, Linux and BSD. - -To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][]. - -All code changes should be internal pull requests. - -Releases are tagged using [Semantic Versioning](http://semver.org/). - -[hub]: https://github.com/github/hub -[am]: http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs +[goon]: https://github.com/arp242/goon +[Vagrant]: https://www.vagrantup.com/ +[integration_test.go]: /integration_test.go diff --git a/vendor/github.com/fsnotify/fsnotify/LICENSE b/vendor/github.com/fsnotify/fsnotify/LICENSE index e180c8fb0..fb03ade75 100644 --- a/vendor/github.com/fsnotify/fsnotify/LICENSE +++ b/vendor/github.com/fsnotify/fsnotify/LICENSE @@ -1,28 +1,25 @@ -Copyright (c) 2012 The Go Authors.

This is not +an implementation of logging - it is an API. In fact it is two APIs with two +different sets of users. + +The `Logger` type is intended for application and library authors. It provides +a relatively small API which can be used everywhere you want to emit logs. It +defers the actual act of writing logs (to files, to stdout, or whatever) to the +`LogSink` interface. + +The `LogSink` interface is intended for logging library implementers. It is a +pure interface which can be implemented by logging frameworks to provide the actual logging +functionality. + +This decoupling allows application and library developers to write code in +terms of `logr.Logger` (which has very low dependency fan-out) while the +implementation of logging is managed "up stack" (e.g. in or near `main()`.) +Application developers can then switch out implementations as necessary. + +Many people assert that libraries should not be logging, and as such efforts +like this are pointless. Those people are welcome to convince the authors of +the tens-of-thousands of libraries that *DO* write logs that they are all +wrong. In the meantime, logr takes a more practical approach. + +## Typical usage + +Somewhere, early in an application's life, it will make a decision about which +logging library (implementation) it actually wants to use. Something like: + +``` + func main() { + // ... other setup code ... + + // Create the "root" logger. We have chosen the "logimpl" implementation, + // which takes some initial parameters and returns a logr.Logger. + logger := logimpl.New(param1, param2) + + // ... other setup code ... +``` + +Most apps will call into other libraries, create structures to govern the flow, +etc. The `logr.Logger` object can be passed to these other libraries, stored +in structs, or even used as a package-global variable, if needed. For example: + +``` + app := createTheAppObject(logger) + app.Run() +``` + +Outside of this early setup, no other packages need to know about the choice of +implementation. They write logs in terms of the `logr.Logger` that they +received: + +``` + type appObject struct { + // ... other fields ... + logger logr.Logger + // ... other fields ... + } + + func (app *appObject) Run() { + app.logger.Info("starting up", "timestamp", time.Now()) + + // ... app code ... +``` + +## Background + +If the Go standard library had defined an interface for logging, this project +probably would not be needed. Alas, here we are. + +When the Go developers started developing such an interface with +[slog](https://github.com/golang/go/issues/56345), they adopted some of the +logr design but also left out some parts and changed others: + +| Feature | logr | slog | +|---------|------|------| +| High-level API | `Logger` (passed by value) | `Logger` (passed by [pointer](https://github.com/golang/go/issues/59126)) | +| Low-level API | `LogSink` | `Handler` | +| Stack unwinding | done by `LogSink` | done by `Logger` | +| Skipping helper functions | `WithCallDepth`, `WithCallStackHelper` | [not supported by Logger](https://github.com/golang/go/issues/59145) | +| Generating a value for logging on demand | `Marshaler` | `LogValuer` | +| Log levels | >= 0, higher meaning "less important" | positive and negative, with 0 for "info" and higher meaning "more important" | +| Error log entries | always logged, don't have a verbosity level | normal log entries with level >= `LevelError` | +| Passing logger via context | `NewContext`, `FromContext` | no API | +| Adding a name to a logger | `WithName` | no API | +| Modify verbosity of log entries in a call chain | `V` | no API | +| Grouping of key/value pairs | not supported | `WithGroup`, `GroupValue` | + +The high-level slog API is explicitly meant to be one of many different APIs +that can be layered on top of a shared `slog.Handler`. logr is one such +alternative API, with [interoperability](#slog-interoperability) provided by the [`slogr`](slogr) +package. + +### Inspiration + +Before you consider this package, please read [this blog post by the +inimitable Dave Cheney][warning-makes-no-sense]. We really appreciate what +he has to say, and it largely aligns with our own experiences. + +### Differences from Dave's ideas + +The main differences are: + +1. Dave basically proposes doing away with the notion of a logging API in favor +of `fmt.Printf()`. We disagree, especially when you consider things like output +locations, timestamps, file and line decorations, and structured logging. This +package restricts the logging API to just 2 types of logs: info and error. + +Info logs are things you want to tell the user which are not errors. Error +logs are, well, errors. If your code receives an `error` from a subordinate +function call and is logging that `error` *and not returning it*, use error +logs. + +2. Verbosity-levels on info logs. This gives developers a chance to indicate +arbitrary grades of importance for info logs, without assigning names with +semantic meaning such as "warning", "trace", and "debug." Superficially this +may feel very similar, but the primary difference is the lack of semantics. +Because verbosity is a numerical value, it's safe to assume that an app running +with higher verbosity means more (and less important) logs will be generated. + +## Implementations (non-exhaustive) + +There are implementations for the following logging libraries: + +- **a function** (can bridge to non-structured libraries): [funcr](https://github.com/go-logr/logr/tree/master/funcr) +- **a testing.T** (for use in Go tests, with JSON-like output): [testr](https://github.com/go-logr/logr/tree/master/testr) +- **github.com/google/glog**: [glogr](https://github.com/go-logr/glogr) +- **k8s.io/klog** (for Kubernetes): [klogr](https://git.k8s.io/klog/klogr) +- **a testing.T** (with klog-like text output): [ktesting](https://git.k8s.io/klog/ktesting) +- **go.uber.org/zap**: [zapr](https://github.com/go-logr/zapr) +- **log** (the Go standard library logger): [stdr](https://github.com/go-logr/stdr) +- **github.com/sirupsen/logrus**: [logrusr](https://github.com/bombsimon/logrusr) +- **github.com/wojas/genericr**: [genericr](https://github.com/wojas/genericr) (makes it easy to implement your own backend) +- **logfmt** (Heroku style [logging](https://www.brandur.org/logfmt)): [logfmtr](https://github.com/iand/logfmtr) +- **github.com/rs/zerolog**: [zerologr](https://github.com/go-logr/zerologr) +- **github.com/go-kit/log**: [gokitlogr](https://github.com/tonglil/gokitlogr) (also compatible with github.com/go-kit/kit/log since v0.12.0) +- **bytes.Buffer** (writing to a buffer): [bufrlogr](https://github.com/tonglil/buflogr) (useful for ensuring values were logged, like during testing) + +## slog interoperability + +Interoperability goes both ways, using the `logr.Logger` API with a `slog.Handler` +and using the `slog.Logger` API with a `logr.LogSink`. [slogr](./slogr) provides `NewLogr` and +`NewSlogHandler` API calls to convert between a `logr.Logger` and a `slog.Handler`. +As usual, `slog.New` can be used to wrap such a `slog.Handler` in the high-level +slog API. `slogr` itself leaves that to the caller. + +## Using a `logr.Sink` as backend for slog + +Ideally, a logr sink implementation should support both logr and slog by +implementing both the normal logr interface(s) and `slogr.SlogSink`. Because +of a conflict in the parameters of the common `Enabled` method, it is [not +possible to implement both slog.Handler and logr.Sink in the same +type](https://github.com/golang/go/issues/59110). + +If both are supported, log calls can go from the high-level APIs to the backend +without the need to convert parameters. `NewLogr` and `NewSlogHandler` can +convert back and forth without adding additional wrappers, with one exception: +when `Logger.V` was used to adjust the verbosity for a `slog.Handler`, then +`NewSlogHandler` has to use a wrapper which adjusts the verbosity for future +log calls. + +Such an implementation should also support values that implement specific +interfaces from both packages for logging (`logr.Marshaler`, `slog.LogValuer`, +`slog.GroupValue`). logr does not convert those. + +Not supporting slog has several drawbacks: +- Recording source code locations works correctly if the handler gets called + through `slog.Logger`, but may be wrong in other cases. That's because a + `logr.Sink` does its own stack unwinding instead of using the program counter + provided by the high-level API. +- slog levels <= 0 can be mapped to logr levels by negating the level without a + loss of information. But all slog levels > 0 (e.g. `slog.LevelWarning` as + used by `slog.Logger.Warn`) must be mapped to 0 before calling the sink + because logr does not support "more important than info" levels. +- The slog group concept is supported by prefixing each key in a key/value + pair with the group names, separated by a dot. For structured output like + JSON it would be better to group the key/value pairs inside an object. +- Special slog values and interfaces don't work as expected. +- The overhead is likely to be higher. + +These drawbacks are severe enough that applications using a mixture of slog and +logr should switch to a different backend. + +## Using a `slog.Handler` as backend for logr + +Using a plain `slog.Handler` without support for logr works better than the +other direction: +- All logr verbosity levels can be mapped 1:1 to their corresponding slog level + by negating them. +- Stack unwinding is done by the `slogr.SlogSink` and the resulting program + counter is passed to the `slog.Handler`. +- Names added via `Logger.WithName` are gathered and recorded in an additional + attribute with `logger` as key and the names separated by slash as value. +- `Logger.Error` is turned into a log record with `slog.LevelError` as level + and an additional attribute with `err` as key, if an error was provided. + +The main drawback is that `logr.Marshaler` will not be supported. Types should +ideally support both `logr.Marshaler` and `slog.Valuer`. If compatibility +with logr implementations without slog support is not important, then +`slog.Valuer` is sufficient. + +## Context support for slog + +Storing a logger in a `context.Context` is not supported by +slog. `logr.NewContext` and `logr.FromContext` can be used with slog like this +to fill this gap: + + func HandlerFromContext(ctx context.Context) slog.Handler { + logger, err := logr.FromContext(ctx) + if err == nil { + return slogr.NewSlogHandler(logger) + } + return slog.Default().Handler() + } + + func ContextWithHandler(ctx context.Context, handler slog.Handler) context.Context { + return logr.NewContext(ctx, slogr.NewLogr(handler)) + } + +The downside is that storing and retrieving a `slog.Handler` needs more +allocations compared to using a `logr.Logger`. Therefore the recommendation is +to use the `logr.Logger` API in code which uses contextual logging. + +## FAQ + +### Conceptual + +#### Why structured logging? + +- **Structured logs are more easily queryable**: Since you've got + key-value pairs, it's much easier to query your structured logs for + particular values by filtering on the contents of a particular key -- + think searching request logs for error codes, Kubernetes reconcilers for + the name and namespace of the reconciled object, etc. + +- **Structured logging makes it easier to have cross-referenceable logs**: + Similarly to searchability, if you maintain conventions around your + keys, it becomes easy to gather all log lines related to a particular + concept. + +- **Structured logs allow better dimensions of filtering**: if you have + structure to your logs, you've got more precise control over how much + information is logged -- you might choose in a particular configuration + to log certain keys but not others, only log lines where a certain key + matches a certain value, etc., instead of just having v-levels and names + to key off of. + +- **Structured logs better represent structured data**: sometimes, the + data that you want to log is inherently structured (think tuple-link + objects.) Structured logs allow you to preserve that structure when + outputting. + +#### Why V-levels? + +**V-levels give operators an easy way to control the chattiness of log +operations**. V-levels provide a way for a given package to distinguish +the relative importance or verbosity of a given log message. Then, if +a particular logger or package is logging too many messages, the user +of the package can simply change the v-levels for that library. + +#### Why not named levels, like Info/Warning/Error? + +Read [Dave Cheney's post][warning-makes-no-sense]. Then read [Differences +from Dave's ideas](#differences-from-daves-ideas). + +#### Why not allow format strings, too? + +**Format strings negate many of the benefits of structured logs**: + +- They're not easily searchable without resorting to fuzzy searching, + regular expressions, etc. + +- They don't store structured data well, since contents are flattened into + a string. + +- They're not cross-referenceable. + +- They don't compress easily, since the message is not constant. + +(Unless you turn positional parameters into key-value pairs with numerical +keys, at which point you've gotten key-value logging with meaningless +keys.) + +### Practical + +#### Why key-value pairs, and not a map? + +Key-value pairs are *much* easier to optimize, especially around +allocations. Zap (a structured logger that inspired logr's interface) has +[performance measurements](https://github.com/uber-go/zap#performance) +that show this quite nicely. + +While the interface ends up being a little less obvious, you get +potentially better performance, plus avoid making users type +`map[string]string{}` every time they want to log. + +#### What if my V-levels differ between libraries? + +That's fine. Control your V-levels on a per-logger basis, and use the +`WithName` method to pass different loggers to different libraries. + +Generally, you should take care to ensure that you have relatively +consistent V-levels within a given logger, however, as this makes deciding +on what verbosity of logs to request easier. + +#### But I really want to use a format string! + +That's not actually a question. Assuming your question is "how do +I convert my mental model of logging with format strings to logging with +constant messages": + +1. Figure out what the error actually is, as you'd write in a TL;DR style, + and use that as a message. + +2. For every place you'd write a format specifier, look to the word before + it, and add that as a key value pair. + +For instance, consider the following examples (all taken from spots in the +Kubernetes codebase): + +- `klog.V(4).Infof("Client is returning errors: code %v, error %v", + responseCode, err)` becomes `logger.Error(err, "client returned an + error", "code", responseCode)` + +- `klog.V(4).Infof("Got a Retry-After %ds response for attempt %d to %v", + seconds, retries, url)` becomes `logger.V(4).Info("got a retry-after + response when requesting url", "attempt", retries, "after + seconds", seconds, "url", url)` + +If you *really* must use a format string, use it in a key's value, and +call `fmt.Sprintf` yourself. For instance: `log.Printf("unable to +reflect over type %T")` becomes `logger.Info("unable to reflect over +type", "type", fmt.Sprintf("%T"))`. In general though, the cases where +this is necessary should be few and far between. + +#### How do I choose my V-levels? + +This is basically the only hard constraint: increase V-levels to denote +more verbose or more debug-y logs. + +Otherwise, you can start out with `0` as "you always want to see this", +`1` as "common logging that you might *possibly* want to turn off", and +`10` as "I would like to performance-test your log collection stack." + +Then gradually choose levels in between as you need them, working your way +down from 10 (for debug and trace style logs) and up from 1 (for chattier +info-type logs). For reference, slog pre-defines -4 for debug logs +(corresponds to 4 in logr), which matches what is +[recommended for Kubernetes](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/logging.md#what-method-to-use). + +#### How do I choose my keys? + +Keys are fairly flexible, and can hold more or less any string +value. For best compatibility with implementations and consistency +with existing code in other projects, there are a few conventions you +should consider. + +- Make your keys human-readable. +- Constant keys are generally a good idea. +- Be consistent across your codebase. +- Keys should naturally match parts of the message string. +- Use lower case for simple keys and + [lowerCamelCase](https://en.wiktionary.org/wiki/lowerCamelCase) for + more complex ones. Kubernetes is one example of a project that has + [adopted that + convention](https://github.com/kubernetes/community/blob/HEAD/contributors/devel/sig-instrumentation/migration-to-structured-logging.md#name-arguments). + +While key names are mostly unrestricted (and spaces are acceptable), +it's generally a good idea to stick to printable ascii characters, or at +least match the general character set of your log lines. + +#### Why should keys be constant values? + +The point of structured logging is to make later log processing easier. Your +keys are, effectively, the schema of each log message. If you use different +keys across instances of the same log line, you will make your structured logs +much harder to use. `Sprintf()` is for values, not for keys! + +#### Why is this not a pure interface? + +The Logger type is implemented as a struct in order to allow the Go compiler to +optimize things like high-V `Info` logs that are not triggered. Not all of +these implementations are implemented yet, but this structure was suggested as +a way to ensure they *can* be implemented. All of the real work is behind the +`LogSink` interface. + +[warning-makes-no-sense]: http://dave.cheney.net/2015/11/05/lets-talk-about-logging diff --git a/vendor/github.com/go-logr/logr/SECURITY.md b/vendor/github.com/go-logr/logr/SECURITY.md new file mode 100644 index 000000000..1ca756fc7 --- /dev/null +++ b/vendor/github.com/go-logr/logr/SECURITY.md @@ -0,0 +1,18 @@ +# Security Policy + +If you have discovered a security vulnerability in this project, please report it +privately. **Do not disclose it as a public issue.** This gives us time to work with you +to fix the issue before public exposure, reducing the chance that the exploit will be +used before a patch is released. + +You may submit the report in the following ways: + +- send an email to go-logr-security@googlegroups.com +- send us a [private vulnerability report](https://github.com/go-logr/logr/security/advisories/new) + +Please provide the following information in your report: + +- A description of the vulnerability and its impact +- How to reproduce the issue + +We ask that you give us 90 days to work on a fix before public exposure. diff --git a/vendor/github.com/go-logr/logr/discard.go b/vendor/github.com/go-logr/logr/discard.go new file mode 100644 index 000000000..99fe8be93 --- /dev/null +++ b/vendor/github.com/go-logr/logr/discard.go @@ -0,0 +1,24 @@ +/* +Copyright 2020 The logr 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 logr + +// Discard returns a Logger that discards all messages logged to it.

Logger is a concrete type with +// methods, which defers the actual logging to a LogSink interface. The main +// methods of Logger are Info() and Error().

Error() messages are +// always logged, regardless of the current verbosity. If there is no error +// instance available, passing nil is valid. +// +// # Verbosity +// +// Often we want to log information only when the application in "verbose +// mode". To write log lines that are more verbose, Logger has a V() method. +// The higher the V-level of a log line, the less critical it is considered. +// Log-lines with V-levels that are not enabled (as per the LogSink) will not +// be written. Level V(0) is the default, and logger.V(0).Info() has the same +// meaning as logger.Info(). Negative V-levels have the same meaning as V(0). +// Error messages do not have a verbosity level and are always logged. +// +// Where we might have written: +// +// if flVerbose >= 2 { +// log.Printf("an unusual thing happened") +// } +// +// We can write: +// +// logger.V(2).Info("an unusual thing happened") +// +// # Logger Names +// +// Logger instances can have name strings so that all messages logged through +// that instance have additional context. For example, you might want to add +// a subsystem name: +// +// logger.WithName("compactor").Info("started", "time", time.Now()) +// +// The WithName() method returns a new Logger, which can be passed to +// constructors or other functions for further use. Repeated use of WithName() +// will accumulate name "segments". These name segments will be joined in some +// way by the LogSink implementation. It is strongly recommended that name +// segments contain simple identifiers (letters, digits, and hyphen), and do +// not contain characters that could muddle the log output or confuse the +// joining operation (e.g. whitespace, commas, periods, slashes, brackets, +// quotes, etc). +// +// # Saved Values +// +// Logger instances can store any number of key/value pairs, which will be +// logged alongside all messages logged through that instance. For example, +// you might want to create a Logger instance per managed object: +// +// With the standard log package, we might write: +// +// log.Printf("decided to set field foo to value %q for object %s/%s", +// targetValue, object.Namespace, object.Name) +// +// With logr we'd write: +// +// // Elsewhere: set up the logger to log the object name. +// obj.logger = mainLogger.WithValues( +// "name", obj.name, "namespace", obj.namespace) +// +// // later on... +// obj.logger.Info("setting foo", "value", targetValue) +// +// # Best Practices +// +// Logger has very few hard rules, with the goal that LogSink implementations +// might have a lot of freedom to differentiate. There are, however, some +// things to consider. +// +// The log message consists of a constant message attached to the log line. +// This should generally be a simple description of what's occurring, and should +// never be a format string. Variable information can then be attached using +// named values. +// +// Keys are arbitrary strings, but should generally be constant values. Values +// may be any Go value, but how the value is formatted is determined by the +// LogSink implementation. +// +// Logger instances are meant to be passed around by value. Code that receives +// such a value can call its methods without having to check whether the +// instance is ready for use. +// +// The zero logger (= Logger{}) is identical to Discard() and discards all log +// entries. Code that receives a Logger by value can simply call it, the methods +// will never crash. For cases where passing a logger is optional, a pointer to Logger +// should be used. +// +// # Key Naming Conventions +// +// Keys are not strictly required to conform to any specification or regex, but +// it is recommended that they: +// - be human-readable and meaningful (not auto-generated or simple ordinals) +// - be constant (not dependent on input data) +// - contain only printable characters +// - not contain whitespace or punctuation +// - use lower case for simple keys and lowerCamelCase for more complex ones +// +// These guidelines help ensure that log data is processed properly regardless +// of the log implementation. For example, log implementations will try to +// output JSON data or will store data for later database (e.g. SQL) queries. +// +// While users are generally free to use key names of their choice, it's +// generally best to avoid using the following keys, as they're frequently used +// by implementations: +// - "caller": the calling information (file/line) of a particular log line +// - "error": the underlying error value in the `Error` method +// - "level": the log level +// - "logger": the name of the associated logger +// - "msg": the log message +// - "stacktrace": the stack trace associated with a particular log line or +// error (often from the `Error` message) +// - "ts": the timestamp for a log line +// +// Implementations are encouraged to make use of these keys to represent the +// above concepts, when necessary (for example, in a pure-JSON output form, it +// would be necessary to represent at least message and timestamp as ordinary +// named values). +// +// # Break Glass +// +// Implementations may choose to give callers access to the underlying +// logging implementation. The recommended pattern for this is: +// +// // Underlier exposes access to the underlying logging implementation. +// // Since callers only have a logr.Logger, they have to know which +// // implementation is in use, so this interface is less of an abstraction +// // and more of way to test type conversion. +// type Underlier interface { +// GetUnderlying() +// } +// +// Logger grants access to the sink to enable type assertions like this: +// +// func DoSomethingWithImpl(log logr.Logger) { +// if underlier, ok := log.GetSink().(impl.Underlier); ok { +// implLogger := underlier.GetUnderlying() +// ... +// } +// } +// +// Custom `With*` functions can be implemented by copying the complete +// Logger struct and replacing the sink in the copy: +// +// // WithFooBar changes the foobar parameter in the log sink and returns a +// // new logger with that modified sink.

In case of a REST custom method, -// other definitions may be used. Where the mask applies will be -// clearly documented together with its declaration in the API. In -// any case, the effect on the returned resource/resources is required -// behavior for APIs. -// -// # Field Masks in Update Operations -// -// A field mask in update operations specifies which fields of the -// targeted resource are going to be updated. The API is required -// to only change the values of the fields as specified in the mask -// and leave the others untouched. If a resource is passed in to -// describe the updated values, the API ignores the values of all -// fields not covered by the mask. -// -// If a repeated field is specified for an update operation, new values will -// be appended to the existing repeated field in the target resource.

If this is unwanted -// behavior, a specific service may require a client to always specify -// a field mask, producing an error if not. -// -// As with get operations, the location of the resource which -// describes the updated values in the request message depends on the -// operation kind. In any case, the effect of the field mask is -// required to be honored by the API. -// -// ## Considerations for HTTP REST -// -// The HTTP kind of an update operation which uses a field mask must -// be set to PATCH instead of PUT in order to satisfy HTTP semantics -// (PUT must only be used for full updates). -// -// # JSON Encoding of Field Masks -// -// In JSON, a field mask is encoded as a single string where paths are -// separated by a comma.

[`docker-credential-gcr`](https://github.com/GoogleCloudPlatform/docker-credential-gcr).) +The `DefaultKeychain` will use credentials as described in your Docker config file -- usually

[`google.NewGcloudAuthenticator`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/v1/google#NewGcloudAuthenticator) for more information. + +To emulate other credential helpers without requiring them to be available as executables, [`NewKeychainFromHelper`](https://pkg.go.dev/github.com/google/go-containerregistry/pkg/authn#NewKeychainFromHelper) provides an adapter that takes a Go implementation satisfying a subset of the [`credentials.Helper`](https://pkg.go.dev/github.com/docker/docker-credential-helpers/credentials#Helper) interface, and makes it available as a `Keychain`. + +This means that you can emulate, for example, [Amazon ECR's `docker-credential-ecr-login` credential helper](https://github.com/awslabs/amazon-ecr-credential-helper) using the same implementation: +

api.DefaultClientFactory{}} + img, err := remote.Get(ref, remote.WithAuthFromKeychain(authn.NewKeychainFromHelper(ecrHelper))) + if err != nil { + panic(err) + } + // ... +} +``` + +Likewise, you can emulate [Azure's ACR `docker-credential-acr-env` credential helper](https://github.com/chrismellard/docker-credential-acr-env): + +```go +import ( +

implementations, which will be checked in order when credentials are needed. + +For example: + +```go +kc := authn.NewMultiKeychain( + authn.DefaultKeychain, + google.Keychain, + authn.NewKeychainFromHelper(ecr.ECRHelper{ClientFactory: api.DefaultClientFactory{}}), + authn.NewKeychainFromHelper(acr.ACRCredHelper{}), +) +``` + +This multi-keychain will: + +- first check for

- See Details Both compression and decompression now supports "synchronous" stream operations. This means that whenever "concurrency" is set to 1, they will operate without spawning goroutines. Stream decompression is now faster on asynchronous, since the goroutine allocation much more effectively splits the workload. On typical streams this will typically use 2 cores fully for decompression. When a stream has finished decoding no goroutines will be left over, so decoders can now safely be pooled and still be garbage collected. While the release has been extensively tested, it is recommended to testing when upgrading. +

The basic +// algorithm predates, and is a little fancier than, an algorithm +// published in the late 1980's by Ratcliff and Obershelp under the +// hyperbolic name "gestalt pattern matching".

Unlike e.g. UNIX(tm) diff, the fundamental notion is the +// longest *contiguous* & junk-free matching subsequence. That's what +// catches peoples' eyes. The Windows(tm) windiff has another interesting +// notion, pairing up elements that appear uniquely in each sequence. +// That, and the method here, appear to yield more intuitive difference +// reports than does diff.

" lines in HTML files).

It aims to make it easier for your users to learn how to use your program.

Note that bash 4.4 or higher is required for the prompt to appear when an Active Help message is printed. +- Zsh + +## Adding Active Help messages + +As Active Help uses the shell completion system, the implementation of Active Help messages is done by enhancing custom dynamic completions. If you are not familiar with dynamic completions, please refer to [Shell Completions](shell_completions.md). + +Adding Active Help is done through the use of the `cobra.AppendActiveHelp(...)` function, where the program repeatedly adds Active Help messages to the list of completions. Keep reading for details. + +### Active Help for nouns + +Adding Active Help when completing a noun is done within the `ValidArgsFunction(...)` of a command. Please notice the use of `cobra.AppendActiveHelp(...)` in the following example: + +```go +cmd := &cobra.Command{ + Use: "add [NAME] [URL]", + Short: "add a chart repository", + Args: require.ExactArgs(2), + RunE: func(cmd *cobra.Command, args []string) error { + return addRepo(args) + }, + ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { + var comps []string + if len(args) == 0 { + comps = cobra.AppendActiveHelp(comps, "You must choose a name for the repo you are adding") + } else if len(args) == 1 { + comps = cobra.AppendActiveHelp(comps, "You must specify the URL for the repo you are adding") + } else { + comps = cobra.AppendActiveHelp(comps, "This command does not take any more arguments") + } + return comps, cobra.ShellCompDirectiveNoFileComp + }, +} +``` +The example above defines the completions (none, in this specific example) as well as the Active Help messages for the `helm repo add` command. It yields the following behavior: +``` +bash-5.1$ helm repo add [tab] +You must choose a name for the repo you are adding + +bash-5.1$ helm repo add grafana [tab] +You must specify the URL for the repo you are adding + +bash-5.1$ helm repo add grafana https://grafana.github.io/helm-charts [tab] +This command does not take any more arguments +``` +**Hint**: As can be seen in the above example, a good place to use Active Help messages is when the normal completion system does not provide any suggestions. In such cases, Active Help nicely supplements the normal shell completions. + +### Active Help for flags + +Providing Active Help for flags is done in the same fashion as for nouns, but using the completion function registered for the flag. For example: +```go +_ = cmd.RegisterFlagCompletionFunc("version", func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { + if len(args) != 2 { + return cobra.AppendActiveHelp(nil, "You must first specify the chart to install before the --version flag can be completed"), cobra.ShellCompDirectiveNoFileComp + } + return compVersionFlag(args[1], toComplete) + }) +``` +The example above prints an Active Help message when not enough information was given by the user to complete the `--version` flag. +``` +bash-5.1$ bin/helm install myrelease --version 2.0.[tab] +You must first specify the chart to install before the --version flag can be completed + +bash-5.1$ bin/helm install myrelease bitnami/solr --version 2.0.[tab][tab] +2.0.1 2.0.2 2.0.3 +``` + +## User control of Active Help + +You may want to allow your users to disable Active Help or choose between different levels of Active Help. It is entirely up to the program to define the type of configurability of Active Help that it wants to offer, if any. +Allowing to configure Active Help is entirely optional; you can use Active Help in your program without doing anything about Active Help configuration. + +The way to configure Active Help is to use the program's Active Help environment +variable. That variable is named `_ACTIVE_HELP` where `` is the name of your +program in uppercase with any `-` replaced by an `_`. The variable should be set by the user to whatever +Active Help configuration values are supported by the program. + +For example, say `helm` has chosen to support three levels for Active Help: `on`, `off`, `local`. Then a user +would set the desired behavior to `local` by doing `export HELM_ACTIVE_HELP=local` in their shell. + +For simplicity, when in `cmd.ValidArgsFunction(...)` or a flag's completion function, the program should read the +Active Help configuration using the `cobra.GetActiveHelpConfig(cmd)` function and select what Active Help messages +should or should not be added (instead of reading the environment variable directly). + +For example: +```go +ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { + activeHelpLevel := cobra.GetActiveHelpConfig(cmd) + + var comps []string + if len(args) == 0 { + if activeHelpLevel != "off" { + comps = cobra.AppendActiveHelp(comps, "You must choose a name for the repo you are adding") + } + } else if len(args) == 1 { + if activeHelpLevel != "off" { + comps = cobra.AppendActiveHelp(comps, "You must specify the URL for the repo you are adding") + } + } else { + if activeHelpLevel == "local" { + comps = cobra.AppendActiveHelp(comps, "This command does not take any more arguments") + } + } + return comps, cobra.ShellCompDirectiveNoFileComp +}, +``` +**Note 1**: If the `_ACTIVE_HELP` environment variable is set to the string "0", Cobra will automatically disable all Active Help output (even if some output was specified by the program using the `cobra.AppendActiveHelp(...)` function). Using "0" can simplify your code in situations where you want to blindly disable Active Help without having to call `cobra.GetActiveHelpConfig(cmd)` explicitly. + +**Note 2**: If a user wants to disable Active Help for every single program based on Cobra, she can set the environment variable `COBRA_ACTIVE_HELP` to "0". In this case `cobra.GetActiveHelpConfig(cmd)` will return "0" no matter what the variable `_ACTIVE_HELP` is set to. + +**Note 3**: If the user does not set `_ACTIVE_HELP` or `COBRA_ACTIVE_HELP` (which will be a common case), the default value for the Active Help configuration returned by `cobra.GetActiveHelpConfig(cmd)` will be the empty string. +## Active Help with Cobra's default completion command + +Cobra provides a default `completion` command for programs that wish to use it. +When using the default `completion` command, Active Help is configurable in the same +fashion as described above using environment variables. You may wish to document this in more +details for your users. + +## Debugging Active Help + +Debugging your Active Help code is done in the same way as debugging your dynamic completion code, which is with Cobra's hidden `__complete` command. Please refer to [debugging shell completion](shell_completions.md#debugging) for details. + +When debugging with the `__complete` command, if you want to specify different Active Help configurations, you should use the active help environment variable. That variable is named `_ACTIVE_HELP` where any `-` is replaced by an `_`. For example, we can test deactivating some Active Help as shown below: +``` +$ HELM_ACTIVE_HELP=1 bin/helm __complete install wordpress bitnami/h +bitnami/haproxy +bitnami/harbor +_activeHelp_ WARNING: cannot re-use a name that is still in use +:0 +Completion ended with directive: ShellCompDirectiveDefault + +$ HELM_ACTIVE_HELP=0 bin/helm __complete install wordpress bitnami/h +bitnami/haproxy +bitnami/harbor +:0 +Completion ended with directive: ShellCompDirectiveDefault +``` diff --git a/vendor/github.com/spf13/cobra/args.go b/vendor/github.com/spf13/cobra/args.go index 70e9b2629..2c1f99e78 100644 --- a/vendor/github.com/spf13/cobra/args.go +++ b/vendor/github.com/spf13/cobra/args.go @@ -1,3 +1,17 @@ +// Copyright 2013-2022 The Cobra Authors +// +// Licensed under the Apache License, Version 2.0 (the "License");

(#2743, #2744) + +### Security + +- Upgrade `go.opentelemetry.io/proto/otlp` from `v0.12.0` to `v0.12.1`. + This includes an indirect upgrade of `github.com/grpc-ecosystem/grpc-gateway` which resolves [a vulnerability](https://nvd.nist.gov/vuln/detail/CVE-2019-11254) from `gopkg.in/yaml.v2` in version `v2.2.3`. (#2724, #2728) + +## [1.6.0/0.28.0] - 2022-03-23 + +### ⚠️ Notice ⚠️ + +This update is a breaking change of the unstable Metrics API. +Code instrumented with the `go.opentelemetry.io/otel/metric` will need to be modified. + +### Added + +- Add metrics exponential histogram support. + New mapping functions have been made available in `sdk/metric/aggregator/exponential/mapping` for other OpenTelemetry projects to take dependencies on. (#2502) +- Add Go 1.18 to our compatibility tests. (#2679) +- Allow configuring the Sampler with the `OTEL_TRACES_SAMPLER` and `OTEL_TRACES_SAMPLER_ARG` environment variables. (#2305, #2517) +- Add the `metric/global` for obtaining and setting the global `MeterProvider`. (#2660) + +### Changed + +- The metrics API has been significantly changed to match the revised OpenTelemetry specification. + High-level changes include: + + - Synchronous and asynchronous instruments are now handled by independent `InstrumentProvider`s. + These `InstrumentProvider`s are managed with a `Meter`. + - Synchronous and asynchronous instruments are grouped into their own packages based on value types. + - Asynchronous callbacks can now be registered with a `Meter`. + + Be sure to check out the metric module documentation for more information on how to use the revised API.

(#2418) +- Add span attribute value length limit. + The new `AttributeValueLengthLimit` field is added to the `"go.opentelemetry.io/otel/sdk/trace".SpanLimits` type to configure this limit for a `TracerProvider`. + The default limit for this resource is "unlimited". (#2637) +- Add the `WithRawSpanLimits` option to `go.opentelemetry.io/otel/sdk/trace`. + This option replaces the `WithSpanLimits` option. + Zero or negative values will not be changed to the default value like `WithSpanLimits` does. + Setting a limit to zero will effectively disable the related resource it limits and setting to a negative value will mean that resource is unlimited. + Consequentially, limits should be constructed using `NewSpanLimits` and updated accordingly. (#2637) + +### Changed + +- Drop oldest tracestate `Member` when capacity is reached. (#2592) +- Add event and link drop counts to the exported data from the `oltptrace` exporter.

(#2614, #2625) +- Unlimited span limits are now supported (negative values). (#2636, #2637) + +### Deprecated + +- Deprecated `"go.opentelemetry.io/otel/sdk/trace".WithSpanLimits`. + Use `WithRawSpanLimits` instead. + That option allows setting unlimited and zero limits, this option does not. + This option will be kept until the next major version incremented release. (#2637) + +## [1.4.1] - 2022-02-16 + +### Fixed + +- Fix race condition in reading the dropped spans number for the `BatchSpanProcessor`.

(#2489, #2512) +- Change the `otlpmetric.Client` interface's `UploadMetrics` method to accept a single `ResourceMetrics` instead of a slice of them. (#2491) +- Specify explicit buckets in Prometheus example, fixing issue where example only has `+inf` bucket. (#2419, #2493) +- W3C baggage will now decode urlescaped values. (#2529) +- Baggage members are now only validated once, when calling `NewMember` and not also when adding it to the baggage itself. (#2522) +- The order attributes are dropped from spans in the `go.opentelemetry.io/otel/sdk/trace` package when capacity is reached is fixed to be in compliance with the OpenTelemetry specification. + Instead of dropping the least-recently-used attribute, the last added attribute is dropped. + This drop order still only applies to attributes with unique keys not already contained in the span. + If an attribute is added with a key already contained in the span, that attribute is updated to the new value being added. (#2576) + +### Removed + +- Updated `go.opentelemetry.io/proto/otlp` from `v0.11.0` to `v0.12.0`. This version removes a number of deprecated methods.

For debugging information configure to print V(5) logs. (#2343) +- Add the `WithRetry` `Option` and the `RetryConfig` type to the `go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp` package to specify retry behavior consistently. (#2425) +- Add `SpanStatusFromHTTPStatusCodeAndSpanKind` to all `semconv` packages to return a span status code similar to `SpanStatusFromHTTPStatusCode`, but exclude `4XX` HTTP errors as span errors if the span is of server kind. (#2296) + +### Changed + +- The `"go.opentelemetry.io/otel/exporter/otel/otlptrace/otlptracegrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2329) +- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2425) +- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".RetrySettings` type is renamed to `RetryConfig`. (#2425) +- The `go.opentelemetry.io/otel/exporter/otel/*` gRPC exporters now default to using the host's root CA set if none are provided by the user and `WithInsecure` is not specified. (#2432) +- Change `resource.Default` to be evaluated the first time it is called, rather than on import. This allows the caller the option to update `OTEL_RESOURCE_ATTRIBUTES` first, such as with `os.Setenv`. (#2371) + +### Fixed + +- The `go.opentelemetry.io/otel/exporter/otel/*` exporters are updated to handle per-signal and universal endpoints according to the OpenTelemetry specification. + Any per-signal endpoint set via an `OTEL_EXPORTER_OTLP__ENDPOINT` environment variable is now used without modification of the path. + When `OTEL_EXPORTER_OTLP_ENDPOINT` is set, if it contains a path, that path is used as a base path which per-signal paths are appended to. (#2433) +- Basic metric controller updated to use sync.Map to avoid blocking calls (#2381) +- The `go.opentelemetry.io/otel/exporter/jaeger` correctly sets the `otel.status_code` value to be a string of `ERROR` or `OK` instead of an integer code. (#2439, #2440) + +### Deprecated + +- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithMaxAttempts` `Option`, use the new `WithRetry` `Option` instead.

(#2425) + +### Removed + +- Remove the metric Processor's ability to convert cumulative to delta aggregation temporality. (#2350) +- Remove the metric Bound Instruments interface and implementations. (#2399) +- Remove the metric MinMaxSumCount kind aggregation and the corresponding OTLP export path. (#2423) +- Metric SDK removes the "exact" aggregator for histogram instruments, as it performed a non-standard aggregation for OTLP export (creating repeated Gauge points) and worked its way into a number of confusing examples. (#2348) + +## [1.2.0] - 2021-11-12 + +### Changed + +- Metric SDK `export.ExportKind`, `export.ExportKindSelector` types have been renamed to `aggregation.Temporality` and `aggregation.TemporalitySelector` respectively to keep in line with current specification and protocol along with built-in selectors (e.g., `aggregation.CumulativeTemporalitySelector`, ...). (#2274) +- The Metric `Exporter` interface now requires a `TemporalitySelector` method instead of an `ExportKindSelector`. (#2274) +- Metrics API cleanup. The `metric/sdkapi` package has been created to relocate the API-to-SDK interface: + - The following interface types simply moved from `metric` to `metric/sdkapi`: `Descriptor`, `MeterImpl`, `InstrumentImpl`, `SyncImpl`, `BoundSyncImpl`, `AsyncImpl`, `AsyncRunner`, `AsyncSingleRunner`, and `AsyncBatchRunner` + - The following struct types moved and are replaced with type aliases, since they are exposed to the user: `Observation`, `Measurement`. + - The No-op implementations of sync and async instruments are no longer exported, new functions `sdkapi.NewNoopAsyncInstrument()` and `sdkapi.NewNoopSyncInstrument()` are provided instead. (#2271) +- Update the SDK `BatchSpanProcessor` to export all queued spans when `ForceFlush` is called. (#2080, #2335) + +### Added + +- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002) +- Added a new `schema` module to help parse Schema Files in OTEP 0152 format. (#2267) +- Added a new `MapCarrier` to the `go.opentelemetry.io/otel/propagation` package to hold propagated cross-cutting concerns as a `map[string]string` held in memory. (#2334) + +## [1.1.0] - 2021-10-27 + +### Added + +- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002) +- Add the `go.opentelemetry.io/otel/semconv/v1.7.0` package. + The package contains semantic conventions from the `v1.7.0` version of the OpenTelemetry specification. (#2320) +- Add the `go.opentelemetry.io/otel/semconv/v1.6.1` package. + The package contains semantic conventions from the `v1.6.1` version of the OpenTelemetry specification. (#2321) +- Add the `go.opentelemetry.io/otel/semconv/v1.5.0` package. + The package contains semantic conventions from the `v1.5.0` version of the OpenTelemetry specification. (#2322) + - When upgrading from the `semconv/v1.4.0` package note the following name changes: + - `K8SReplicasetUIDKey` -> `K8SReplicaSetUIDKey` + - `K8SReplicasetNameKey` -> `K8SReplicaSetNameKey` + - `K8SStatefulsetUIDKey` -> `K8SStatefulSetUIDKey` + - `k8SStatefulsetNameKey` -> `K8SStatefulSetNameKey` + - `K8SDaemonsetUIDKey` -> `K8SDaemonSetUIDKey` + - `K8SDaemonsetNameKey` -> `K8SDaemonSetNameKey` + +### Changed + +- Links added to a span will be dropped by the SDK if they contain an invalid span context (#2275). + +### Fixed + +- The `"go.opentelemetry.io/otel/semconv/v1.4.0".HTTPServerAttributesFromHTTPRequest` now correctly only sets the HTTP client IP attribute even if the connection was routed with proxies and there are multiple addresses in the `X-Forwarded-For` header. (#2282, #2284) +- The `"go.opentelemetry.io/otel/semconv/v1.4.0".NetAttributesFromHTTPRequest` function correctly handles IPv6 addresses as IP addresses and sets the correct net peer IP instead of the net peer hostname attribute. (#2283, #2285) +- The simple span processor shutdown method deterministically returns the exporter error status if it simultaneously finishes when the deadline is reached. (#2290, #2289) + +## [1.0.1] - 2021-10-01 + +### Fixed + +- json stdout exporter no longer crashes due to concurrency bug. (#2265) + +## [Metrics 0.24.0] - 2021-10-01 + +### Changed + +- NoopMeterProvider is now private and NewNoopMeterProvider must be used to obtain a noopMeterProvider. (#2237) +- The Metric SDK `Export()` function takes a new two-level reader interface for iterating over results one instrumentation library at a time. (#2197) + - The former `"go.opentelemetry.io/otel/sdk/export/metric".CheckpointSet` is renamed `Reader`. + - The new interface is named `"go.opentelemetry.io/otel/sdk/export/metric".InstrumentationLibraryReader`. + +## [1.0.0] - 2021-09-20 + +This is the first stable release for the project. +This release includes an API and SDK for the tracing signal that will comply with the stability guarantees defined by the projects [versioning policy](./VERSIONING.md). + +### Added + +- OTLP trace exporter now sets the `SchemaURL` field in the exported telemetry if the Tracer has `WithSchemaURL` option. (#2242) + +### Fixed + +- Slice-valued attributes can correctly be used as map keys. (#2223) + +### Removed + +- Removed the `"go.opentelemetry.io/otel/exporters/zipkin".WithSDKOptions` function. (#2248) +- Removed the deprecated package `go.opentelemetry.io/otel/oteltest`. (#2234) +- Removed the deprecated package `go.opentelemetry.io/otel/bridge/opencensus/utils`. (#2233) +- Removed deprecated functions, types, and methods from `go.opentelemetry.io/otel/attribute` package. + Use the typed functions and methods added to the package instead. (#2235) + - The `Key.Array` method is removed. + - The `Array` function is removed. + - The `Any` function is removed. + - The `ArrayValue` function is removed. + - The `AsArray` function is removed. + +## [1.0.0-RC3] - 2021-09-02 + +### Added + +- Added `ErrorHandlerFunc` to use a function as an `"go.opentelemetry.io/otel".ErrorHandler`. (#2149) +- Added `"go.opentelemetry.io/otel/trace".WithStackTrace` option to add a stack trace when using `span.RecordError` or when panic is handled in `span.End`. (#2163) +- Added typed slice attribute types and functionality to the `go.opentelemetry.io/otel/attribute` package to replace the existing array type and functions. (#2162) + - `BoolSlice`, `IntSlice`, `Int64Slice`, `Float64Slice`, and `StringSlice` replace the use of the `Array` function in the package. +- Added the `go.opentelemetry.io/otel/example/fib` example package. + Included is an example application that computes Fibonacci numbers. (#2203) + +### Changed + +- Metric instruments have been renamed to match the (feature-frozen) metric API specification: + - ValueRecorder becomes Histogram + - ValueObserver becomes Gauge + - SumObserver becomes CounterObserver + - UpDownSumObserver becomes UpDownCounterObserver + The API exported from this project is still considered experimental. (#2202) +- Metric SDK/API implementation type `InstrumentKind` moves into `sdkapi` sub-package. (#2091) +- The Metrics SDK export record no longer contains a Resource pointer, the SDK `"go.opentelemetry.io/otel/sdk/trace/export/metric".Exporter.Export()` function for push-based exporters now takes a single Resource argument, pull-based exporters use `"go.opentelemetry.io/otel/sdk/metric/controller/basic".Controller.Resource()`. (#2120) +- The JSON output of the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` is harmonized now such that the output is "plain" JSON objects after each other of the form `{ ... } { ... } { ... }`. Earlier the JSON objects describing a span were wrapped in a slice for each `Exporter.ExportSpans` call, like `[ { ... } ][ { ... } { ... } ]`. Outputting JSON object directly after each other is consistent with JSON loggers, and a bit easier to parse and read. (#2196) +- Update the `NewTracerConfig`, `NewSpanStartConfig`, `NewSpanEndConfig`, and `NewEventConfig` function in the `go.opentelemetry.io/otel/trace` package to return their respective configurations as structs instead of pointers to the struct. (#2212) + +### Deprecated + +- The `go.opentelemetry.io/otel/bridge/opencensus/utils` package is deprecated. + All functionality from this package now exists in the `go.opentelemetry.io/otel/bridge/opencensus` package. + The functions from that package should be used instead.

(#2162) +- The `"go.opentelemetry.io/otel/attribute".Any` function is deprecated. + Use the typed functions instead. (#2181) +- The `go.opentelemetry.io/otel/oteltest` package is deprecated. + The `"go.opentelemetry.io/otel/sdk/trace/tracetest".SpanRecorder` can be registered with the default SDK (`go.opentelemetry.io/otel/sdk/trace`) as a `SpanProcessor` and used as a replacement for this deprecated package. (#2188) + +### Removed + +- Removed metrics test package `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#2105) + +### Fixed + +- The `fromEnv` detector no longer throws an error when `OTEL_RESOURCE_ATTRIBUTES` environment variable is not set or empty. (#2138) +- Setting the global `ErrorHandler` with `"go.opentelemetry.io/otel".SetErrorHandler` multiple times is now supported. (#2160, #2140) +- The `"go.opentelemetry.io/otel/attribute".Any` function now supports `int32` values. (#2169) +- Multiple calls to `"go.opentelemetry.io/otel/sdk/metric/controller/basic".WithResource()` are handled correctly, and when no resources are provided `"go.opentelemetry.io/otel/sdk/resource".Default()` is used. (#2120) +- The `WithoutTimestamps` option for the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter causes the exporter to correctly omit timestamps. (#2195) +- Fixed typos in resources.go. (#2201) + +## [1.0.0-RC2] - 2021-07-26 + +### Added + +- Added `WithOSDescription` resource configuration option to set OS (Operating System) description resource attribute (`os.description`). (#1840) +- Added `WithOS` resource configuration option to set all OS (Operating System) resource attributes at once. (#1840) +- Added the `WithRetry` option to the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package. + This option is a replacement for the removed `WithMaxAttempts` and `WithBackoff` options. (#2095) +- Added API `LinkFromContext` to return Link which encapsulates SpanContext from provided context and also encapsulates attributes. (#2115) +- Added a new `Link` type under the SDK `otel/sdk/trace` package that counts the number of attributes that were dropped for surpassing the `AttributePerLinkCountLimit` configured in the Span's `SpanLimits`. + This new type replaces the equal-named API `Link` type found in the `otel/trace` package for most usages within the SDK. + For example, instances of this type are now returned by the `Links()` function of `ReadOnlySpan`s provided in places like the `OnEnd` function of `SpanProcessor` implementations. (#2118) +- Added the `SpanRecorder` type to the `go.opentelemetry.io/otel/skd/trace/tracetest` package. + This type can be used with the default SDK as a `SpanProcessor` during testing. (#2132) + +### Changed + +- The `SpanModels` function is now exported from the `go.opentelemetry.io/otel/exporters/zipkin` package to convert OpenTelemetry spans into Zipkin model spans. (#2027) +- Rename the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".RetrySettings` to `RetryConfig`. (#2095) + +### Deprecated + +- The `TextMapCarrier` and `TextMapPropagator` from the `go.opentelemetry.io/otel/oteltest` package and their associated creation functions (`TextMapCarrier`, `NewTextMapPropagator`) are deprecated. (#2114) +- The `Harness` type from the `go.opentelemetry.io/otel/oteltest` package and its associated creation function, `NewHarness` are deprecated and will be removed in the next release. (#2123) +- The `TraceStateFromKeyValues` function from the `go.opentelemetry.io/otel/oteltest` package is deprecated. + Use the `trace.ParseTraceState` function instead. (#2122) + +### Removed + +- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/jaeger`. (#2020) +- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/zipkin`. (#2020) +- Removed the `"go.opentelemetry.io/otel/sdk/resource".WithBuiltinDetectors` function. + The explicit `With*` options for every built-in detector should be used instead. (#2026 #2097) +- Removed the `WithMaxAttempts` and `WithBackoff` options from the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package. + The retry logic of the package has been updated to match the `otlptracegrpc` package and accordingly a `WithRetry` option is added that should be used instead. (#2095) +- Removed `DroppedAttributeCount` field from `otel/trace.Link` struct. (#2118) + +### Fixed + +- When using WithNewRoot, don't use the parent context for making sampling decisions. (#2032) +- `oteltest.Tracer` now creates a valid `SpanContext` when using `WithNewRoot`. (#2073) +- OS type detector now sets the correct `dragonflybsd` value for DragonFly BSD. (#2092) +- The OTel span status is correctly transformed into the OTLP status in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` package. + This fix will by default set the status to `Unset` if it is not explicitly set to `Ok` or `Error`. (#2099 #2102) +- The `Inject` method for the `"go.opentelemetry.io/otel/propagation".TraceContext` type no longer injects empty `tracestate` values. (#2108) +- Use `6831` as default Jaeger agent port instead of `6832`. (#2131) + +## [Experimental Metrics v0.22.0] - 2021-07-19 + +### Added + +- Adds HTTP support for OTLP metrics exporter. (#2022) + +### Removed + +- Removed the deprecated package `go.opentelemetry.io/otel/exporters/metric/prometheus`. (#2020) + +## [1.0.0-RC1] / 0.21.0 - 2021-06-18 + +With this release we are introducing a split in module versions. The tracing API and SDK are entering the `v1.0.0` Release Candidate phase with `v1.0.0-RC1` +while the experimental metrics API and SDK continue with `v0.x` releases at `v0.21.0`. Modules at major version 1 or greater will not depend on modules +with major version 0. + +### Added + +- Adds `otlpgrpc.WithRetry`option for configuring the retry policy for transient errors on the otlp/gRPC exporter. (#1832) + - The following status codes are defined as transient errors: + | gRPC Status Code | Description | + | ---------------- | ----------- | + | 1 | Cancelled | + | 4 | Deadline Exceeded | + | 8 | Resource Exhausted | + | 10 | Aborted | + | 10 | Out of Range | + | 14 | Unavailable | + | 15 | Data Loss | +- Added `Status` type to the `go.opentelemetry.io/otel/sdk/trace` package to represent the status of a span. (#1874) +- Added `SpanStub` type and its associated functions to the `go.opentelemetry.io/otel/sdk/trace/tracetest` package. + This type can be used as a testing replacement for the `SpanSnapshot` that was removed from the `go.opentelemetry.io/otel/sdk/trace` package. (#1873) +- Adds support for scheme in `OTEL_EXPORTER_OTLP_ENDPOINT` according to the spec. (#1886) +- Adds `trace.WithSchemaURL` option for configuring the tracer with a Schema URL. (#1889) +- Added an example of using OpenTelemetry Go as a trace context forwarder. (#1912) +- `ParseTraceState` is added to the `go.opentelemetry.io/otel/trace` package. + It can be used to decode a `TraceState` from a `tracestate` header string value. (#1937) +- Added `Len` method to the `TraceState` type in the `go.opentelemetry.io/otel/trace` package. + This method returns the number of list-members the `TraceState` holds. (#1937) +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace` that defines a trace exporter that uses a `otlptrace.Client` to send data. + Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` implementing a gRPC `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing .(#1922) +- Added `Baggage`, `Member`, and `Property` types to the `go.opentelemetry.io/otel/baggage` package along with their related functions. (#1967) +- Added `ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext` functions to the `go.opentelemetry.io/otel/baggage` package. + These functions replace the `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions from that package and directly work with the new `Baggage` type. (#1967) +- The `OTEL_SERVICE_NAME` environment variable is the preferred source for `service.name`, used by the environment resource detector if a service name is present both there and in `OTEL_RESOURCE_ATTRIBUTES`. (#1969) +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` implementing an HTTP `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing. (#1963) +- Changes `go.opentelemetry.io/otel/sdk/resource.NewWithAttributes` to require a schema URL. The old function is still available as `resource.NewSchemaless`. This is a breaking change. (#1938) +- Several builtin resource detectors now correctly populate the schema URL. (#1938) +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` that defines a metrics exporter that uses a `otlpmetric.Client` to send data. +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` implementing a gRPC `otlpmetric.Client` and offers convenience functions, `New` and `NewUnstarted`, to create an `otlpmetric.Exporter`.(#1991) +- Added `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter. (#2005) +- Added `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` exporter. (#2005) +- Added a `TracerProvider()` method to the `"go.opentelemetry.io/otel/trace".Span` interface. This can be used to obtain a `TracerProvider` from a given span that utilizes the same trace processing pipeline. (#2009) + +### Changed + +- Make `NewSplitDriver` from `go.opentelemetry.io/otel/exporters/otlp` take variadic arguments instead of a `SplitConfig` item. + `NewSplitDriver` now automatically implements an internal `noopDriver` for `SplitConfig` fields that are not initialized. (#1798) +- `resource.New()` now creates a Resource without builtin detectors. Previous behavior is now achieved by using `WithBuiltinDetectors` Option. (#1810) +- Move the `Event` type from the `go.opentelemetry.io/otel` package to the `go.opentelemetry.io/otel/sdk/trace` package. (#1846) +- CI builds validate against last two versions of Go, dropping 1.14 and adding 1.16. (#1865) +- BatchSpanProcessor now report export failures when calling `ForceFlush()` method. (#1860) +- `Set.Encoded(Encoder)` no longer caches the result of an encoding. (#1855) +- Renamed `CloudZoneKey` to `CloudAvailabilityZoneKey` in Resource semantic conventions according to spec. (#1871) +- The `StatusCode` and `StatusMessage` methods of the `ReadOnlySpan` interface and the `Span` produced by the `go.opentelemetry.io/otel/sdk/trace` package have been replaced with a single `Status` method. + This method returns the status of a span using the new `Status` type. (#1874) +- Updated `ExportSpans` method of the`SpanExporter` interface type to accept `ReadOnlySpan`s instead of the removed `SpanSnapshot`. + This brings the export interface into compliance with the specification in that it now accepts an explicitly immutable type instead of just an implied one. (#1873) +- Unembed `SpanContext` in `Link`. (#1877) +- Generate Semantic conventions from the specification YAML. (#1891) +- Spans created by the global `Tracer` obtained from `go.opentelemetry.io/otel`, prior to a functioning `TracerProvider` being set, now propagate the span context from their parent if one exists. (#1901) +- The `"go.opentelemetry.io/otel".Tracer` function now accepts tracer options. (#1902) +- Move the `go.opentelemetry.io/otel/unit` package to `go.opentelemetry.io/otel/metric/unit`. (#1903) +- Changed `go.opentelemetry.io/otel/trace.TracerConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config.) (#1921) +- Changed `go.opentelemetry.io/otel/trace.SpanConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921) +- Changed `span.End()` now only accepts Options that are allowed at `End()`.

(#1921) +- Changed `go.opentelemetry.io/otel/metric.MeterConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921) +- Refactored option types according to the contribution style guide. (#1882) +- Move the `go.opentelemetry.io/otel/trace.TraceStateFromKeyValues` function to the `go.opentelemetry.io/otel/oteltest` package. + This function is preserved for testing purposes where it may be useful to create a `TraceState` from `attribute.KeyValue`s, but it is not intended for production use. + The new `ParseTraceState` function should be used to create a `TraceState`. (#1931) +- Updated `MarshalJSON` method of the `go.opentelemetry.io/otel/trace.TraceState` type to marshal the type into the string representation of the `TraceState`. (#1931) +- The `TraceState.Delete` method from the `go.opentelemetry.io/otel/trace` package no longer returns an error in addition to a `TraceState`. (#1931) +- Updated `Get` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931) +- Updated `Insert` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a pair of `string`s instead of an `attribute.KeyValue` type. (#1931) +- Updated `Delete` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/stdout` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/metric/prometheus` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985) +- Renamed `NewUnstartedExporter` to `NewUnstarted` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985) +- The `go.opentelemetry.io/otel/semconv` package has been moved to `go.opentelemetry.io/otel/semconv/v1.4.0` to allow for multiple [telemetry schema](https://github.com/open-telemetry/oteps/blob/main/text/0152-telemetry-schemas.md) versions to be used concurrently. (#1987) +- Metrics test helpers in `go.opentelemetry.io/otel/oteltest` have been moved to `go.opentelemetry.io/otel/metric/metrictest`. (#1988) + +### Deprecated + +- The `go.opentelemetry.io/otel/exporters/metric/prometheus` is deprecated, use `go.opentelemetry.io/otel/exporters/prometheus` instead. (#1993) +- The `go.opentelemetry.io/otel/exporters/trace/jaeger` is deprecated, use `go.opentelemetry.io/otel/exporters/jaeger` instead. (#1993) +- The `go.opentelemetry.io/otel/exporters/trace/zipkin` is deprecated, use `go.opentelemetry.io/otel/exporters/zipkin` instead. (#1993) + +### Removed + +- Removed `resource.WithoutBuiltin()`. Use `resource.New()`. (#1810) +- Unexported types `resource.FromEnv`, `resource.Host`, and `resource.TelemetrySDK`, Use the corresponding `With*()` to use individually. (#1810) +- Removed the `Tracer` and `IsRecording` method from the `ReadOnlySpan` in the `go.opentelemetry.io/otel/sdk/trace`. + The `Tracer` method is not a required to be included in this interface and given the mutable nature of the tracer that is associated with a span, this method is not appropriate. + The `IsRecording` method returns if the span is recording or not. + A read-only span value does not need to know if updates to it will be recorded or not. + By definition, it cannot be updated so there is no point in communicating if an update is recorded. (#1873) +- Removed the `SpanSnapshot` type from the `go.opentelemetry.io/otel/sdk/trace` package. + The use of this type has been replaced with the use of the explicitly immutable `ReadOnlySpan` type. + When a concrete representation of a read-only span is needed for testing, the newly added `SpanStub` in the `go.opentelemetry.io/otel/sdk/trace/tracetest` package should be used. (#1873) +- Removed the `Tracer` method from the `Span` interface in the `go.opentelemetry.io/otel/trace` package. + Using the same tracer that created a span introduces the error where an instrumentation library's `Tracer` is used by other code instead of their own. + The `"go.opentelemetry.io/otel".Tracer` function or a `TracerProvider` should be used to acquire a library specific `Tracer` instead. (#1900) + - The `TracerProvider()` method on the `Span` interface may also be used to obtain a `TracerProvider` using the same trace processing pipeline. (#2009) +- The `http.url` attribute generated by `HTTPClientAttributesFromHTTPRequest` will no longer include username or password information. (#1919) +- Removed `IsEmpty` method of the `TraceState` type in the `go.opentelemetry.io/otel/trace` package in favor of using the added `TraceState.Len` method. (#1931) +- Removed `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions in the `go.opentelemetry.io/otel/baggage` package. + Handling of baggage is now done using the added `Baggage` type and related context functions (`ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext`) in that package. (#1967) +- The `InstallNewPipeline` and `NewExportPipeline` creation functions in all the exporters (prometheus, otlp, stdout, jaeger, and zipkin) have been removed. + These functions were deemed premature attempts to provide convenience that did not achieve this aim. (#1985) +- The `go.opentelemetry.io/otel/exporters/otlp` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/otlp/otlptrace` instead. (#1990) +- The `go.opentelemetry.io/otel/exporters/stdout` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` or `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` instead. (#2005) + +### Fixed + +- Only report errors from the `"go.opentelemetry.io/otel/sdk/resource".Environment` function when they are not `nil`. (#1850, #1851) +- The `Shutdown` method of the simple `SpanProcessor` in the `go.opentelemetry.io/otel/sdk/trace` package now honors the context deadline or cancellation. (#1616, #1856) +- BatchSpanProcessor now drops span batches that failed to be exported. (#1860) +- Use `http://localhost:14268/api/traces` as default Jaeger collector endpoint instead of `http://localhost:14250`. (#1898) +- Allow trailing and leading whitespace in the parsing of a `tracestate` header. (#1931) +- Add logic to determine if the channel is closed to fix Jaeger exporter test panic with close closed channel. (#1870, #1973) +- Avoid transport security when OTLP endpoint is a Unix socket. (#2001) + +### Security + +## [0.20.0] - 2021-04-23 + +### Added + +- The OTLP exporter now has two new convenience functions, `NewExportPipeline` and `InstallNewPipeline`, setup and install the exporter in tracing and metrics pipelines. (#1373) +- Adds semantic conventions for exceptions. (#1492) +- Added Jaeger Environment variables: `OTEL_EXPORTER_JAEGER_AGENT_HOST`, `OTEL_EXPORTER_JAEGER_AGENT_PORT` + These environment variables can be used to override Jaeger agent hostname and port (#1752) +- Option `ExportTimeout` was added to batch span processor. (#1755) +- `trace.TraceFlags` is now a defined type over `byte` and `WithSampled(bool) TraceFlags` and `IsSampled() bool` methods have been added to it. (#1770) +- The `Event` and `Link` struct types from the `go.opentelemetry.io/otel` package now include a `DroppedAttributeCount` field to record the number of attributes that were not recorded due to configured limits being reached. (#1771) +- The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771) +- Adds test to check BatchSpanProcessor ignores `OnEnd` and `ForceFlush` post `Shutdown`. (#1772) +- Extract resource attributes from the `OTEL_RESOURCE_ATTRIBUTES` environment variable and merge them with the `resource.Default` resource as well as resources provided to the `TracerProvider` and metric `Controller`. (#1785) +- Added `WithOSType` resource configuration option to set OS (Operating System) type resource attribute (`os.type`). (#1788) +- Added `WithProcess*` resource configuration options to set Process resource attributes. (#1788) + - `process.pid` + - `process.executable.name` + - `process.executable.path` + - `process.command_args` + - `process.owner` + - `process.runtime.name` + - `process.runtime.version` + - `process.runtime.description` +- Adds `k8s.node.name` and `k8s.node.uid` attribute keys to the `semconv` package. (#1789) +- Added support for configuring OTLP/HTTP and OTLP/gRPC Endpoints, TLS Certificates, Headers, Compression and Timeout via Environment Variables. (#1758, #1769 and #1811) + - `OTEL_EXPORTER_OTLP_ENDPOINT` + - `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT` + - `OTEL_EXPORTER_OTLP_METRICS_ENDPOINT` + - `OTEL_EXPORTER_OTLP_HEADERS` + - `OTEL_EXPORTER_OTLP_TRACES_HEADERS` + - `OTEL_EXPORTER_OTLP_METRICS_HEADERS` + - `OTEL_EXPORTER_OTLP_COMPRESSION` + - `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` + - `OTEL_EXPORTER_OTLP_METRICS_COMPRESSION` + - `OTEL_EXPORTER_OTLP_TIMEOUT` + - `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT` + - `OTEL_EXPORTER_OTLP_METRICS_TIMEOUT` + - `OTEL_EXPORTER_OTLP_CERTIFICATE` + - `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` + - `OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE` +- Adds `otlpgrpc.WithTimeout` option for configuring timeout to the otlp/gRPC exporter. (#1821) +- Adds `jaeger.WithMaxPacketSize` option for configuring maximum UDP packet size used when connecting to the Jaeger agent. (#1853) + +### Fixed + +- The `Span.IsRecording` implementation from `go.opentelemetry.io/otel/sdk/trace` always returns false when not being sampled. (#1750) +- The Jaeger exporter now correctly sets tags for the Span status code and message. + This means it uses the correct tag keys (`"otel.status_code"`, `"otel.status_description"`) and does not set the status message as a tag unless it is set on the span. (#1761) +- The Jaeger exporter now correctly records Span event's names using the `"event"` key for a tag. + Additionally, this tag is overridden, as specified in the OTel specification, if the event contains an attribute with that key. (#1768) +- Zipkin Exporter: Ensure mapping between OTel and Zipkin span data complies with the specification. (#1688) +- Fixed typo for default service name in Jaeger Exporter. (#1797) +- Fix flaky OTLP for the reconnnection of the client connection. (#1527, #1814) +- Fix Jaeger exporter dropping of span batches that exceed the UDP packet size limit. + Instead, the exporter now splits the batch into smaller sendable batches. (#1828) + +### Changed + +- Span `RecordError` now records an `exception` event to comply with the semantic convention specification. (#1492) +- Jaeger exporter was updated to use thrift v0.14.1. (#1712) +- Migrate from using internally built and maintained version of the OTLP to the one hosted at `go.opentelemetry.io/proto/otlp`. (#1713) +- Migrate from using `github.com/gogo/protobuf` to `google.golang.org/protobuf` to match `go.opentelemetry.io/proto/otlp`. (#1713) +- The storage of a local or remote Span in a `context.Context` using its SpanContext is unified to store just the current Span. + The Span's SpanContext can now self-identify as being remote or not. + This means that `"go.opentelemetry.io/otel/trace".ContextWithRemoteSpanContext` will now overwrite any existing current Span, not just existing remote Spans, and make it the current Span in a `context.Context`. (#1731) +- Improve OTLP/gRPC exporter connection errors. (#1737) +- Information about a parent span context in a `"go.opentelemetry.io/otel/export/trace".SpanSnapshot` is unified in a new `Parent` field. + The existing `ParentSpanID` and `HasRemoteParent` fields are removed in favor of this. (#1748) +- The `ParentContext` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is updated to hold a `context.Context` containing the parent span. + This changes it to make `SamplingParameters` conform with the OpenTelemetry specification. (#1749) +- Updated Jaeger Environment Variables: `JAEGER_ENDPOINT`, `JAEGER_USER`, `JAEGER_PASSWORD` + to `OTEL_EXPORTER_JAEGER_ENDPOINT`, `OTEL_EXPORTER_JAEGER_USER`, `OTEL_EXPORTER_JAEGER_PASSWORD` in compliance with OTel specification. (#1752) +- Modify `BatchSpanProcessor.ForceFlush` to abort after timeout/cancellation. (#1757) +- The `DroppedAttributeCount` field of the `Span` in the `go.opentelemetry.io/otel` package now only represents the number of attributes dropped for the span itself. + It no longer is a conglomerate of itself, events, and link attributes that have been dropped. (#1771) +- Make `ExportSpans` in Jaeger Exporter honor context deadline. (#1773) +- Modify Zipkin Exporter default service name, use default resource's serviceName instead of empty. (#1777) +- The `go.opentelemetry.io/otel/sdk/export/trace` package is merged into the `go.opentelemetry.io/otel/sdk/trace` package. (#1778) +- The prometheus.InstallNewPipeline example is moved from comment to example test (#1796) +- The convenience functions for the stdout exporter have been updated to return the `TracerProvider` implementation and enable the shutdown of the exporter. (#1800) +- Replace the flush function returned from the Jaeger exporter's convenience creation functions (`InstallNewPipeline` and `NewExportPipeline`) with the `TracerProvider` implementation they create. + This enables the caller to shutdown and flush using the related `TracerProvider` methods. (#1822) +- Updated the Jaeger exporter to have a default endpoint, `http://localhost:14250`, for the collector. (#1824) +- Changed the function `WithCollectorEndpoint` in the Jaeger exporter to no longer accept an endpoint as an argument. + The endpoint can be passed with the `CollectorEndpointOption` using the `WithEndpoint` function or by setting the `OTEL_EXPORTER_JAEGER_ENDPOINT` environment variable value appropriately. (#1824) +- The Jaeger exporter no longer batches exported spans itself, instead it relies on the SDK's `BatchSpanProcessor` for this functionality. (#1830) +- The Jaeger exporter creation functions (`NewRawExporter`, `NewExportPipeline`, and `InstallNewPipeline`) no longer accept the removed `Option` type as a variadic argument. (#1830) + +### Removed + +- Removed Jaeger Environment variables: `JAEGER_SERVICE_NAME`, `JAEGER_DISABLED`, `JAEGER_TAGS` + These environment variables will no longer be used to override values of the Jaeger exporter (#1752) +- No longer set the links for a `Span` in `go.opentelemetry.io/otel/sdk/trace` that is configured to be a new root. + This is unspecified behavior that the OpenTelemetry community plans to standardize in the future. + To prevent backwards incompatible changes when it is specified, these links are removed. (#1726) +- Setting error status while recording error with Span from oteltest package. (#1729) +- The concept of a remote and local Span stored in a context is unified to just the current Span. + Because of this `"go.opentelemetry.io/otel/trace".RemoteSpanContextFromContext` is removed as it is no longer needed. + Instead, `"go.opentelemetry.io/otel/trace".SpanContextFromContex` can be used to return the current Span. + If needed, that Span's `SpanContext.IsRemote()` can then be used to determine if it is remote or not. (#1731) +- The `HasRemoteParent` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is removed. + This field is redundant to the information returned from the `Remote` method of the `SpanContext` held in the `ParentContext` field. (#1749) +- The `trace.FlagsDebug` and `trace.FlagsDeferred` constants have been removed and will be localized to the B3 propagator. (#1770) +- Remove `Process` configuration, `WithProcessFromEnv` and `ProcessFromEnv`, and type from the Jaeger exporter package. + The information that could be configured in the `Process` struct should be configured in a `Resource` instead. (#1776, #1804) +- Remove the `WithDisabled` option from the Jaeger exporter. + To disable the exporter unregister it from the `TracerProvider` or use a no-operation `TracerProvider`. (#1806) +- Removed the functions `CollectorEndpointFromEnv` and `WithCollectorEndpointOptionFromEnv` from the Jaeger exporter. + These functions for retrieving specific environment variable values are redundant of other internal functions and + are not intended for end user use. (#1824) +- Removed the Jaeger exporter `WithSDKOptions` `Option`. + This option was used to set SDK options for the exporter creation convenience functions. + These functions are provided as a way to easily setup or install the exporter with what are deemed reasonable SDK settings for common use cases. + If the SDK needs to be configured differently, the `NewRawExporter` function and direct setup of the SDK with the desired settings should be used. (#1825) +- The `WithBufferMaxCount` and `WithBatchMaxCount` `Option`s from the Jaeger exporter are removed. + The exporter no longer batches exports, instead relying on the SDK's `BatchSpanProcessor` for this functionality. (#1830) +- The Jaeger exporter `Option` type is removed. + The type is no longer used by the exporter to configure anything. + All the previous configurations these options provided were duplicates of SDK configuration. + They have been removed in favor of using the SDK configuration and focuses the exporter configuration to be only about the endpoints it will send telemetry to. (#1830) + +## [0.19.0] - 2021-03-18 + +### Added + +- Added `Marshaler` config option to `otlphttp` to enable otlp over json or protobufs. (#1586) +- A `ForceFlush` method to the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` to flush all registered `SpanProcessor`s. (#1608) +- Added `WithSampler` and `WithSpanLimits` to tracer provider. (#1633, #1702) +- `"go.opentelemetry.io/otel/trace".SpanContext` now has a `remote` property, and `IsRemote()` predicate, that is true when the `SpanContext` has been extracted from remote context data. (#1701) +- A `Valid` method to the `"go.opentelemetry.io/otel/attribute".KeyValue` type. (#1703) + +### Changed + +- `trace.SpanContext` is now immutable and has no exported fields. (#1573) + - `trace.NewSpanContext()` can be used in conjunction with the `trace.SpanContextConfig` struct to initialize a new `SpanContext` where all values are known. +- Update the `ForceFlush` method signature to the `"go.opentelemetry.io/otel/sdk/trace".SpanProcessor` to accept a `context.Context` and return an error. (#1608) +- Update the `Shutdown` method to the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` return an error on shutdown failure. (#1608) +- The SimpleSpanProcessor will now shut down the enclosed `SpanExporter` and gracefully ignore subsequent calls to `OnEnd` after `Shutdown` is called. (#1612) +- `"go.opentelemetry.io/sdk/metric/controller.basic".WithPusher` is replaced with `WithExporter` to provide consistent naming across project. (#1656) +- Added non-empty string check for trace `Attribute` keys. (#1659) +- Add `description` to SpanStatus only when `StatusCode` is set to error. (#1662) +- Jaeger exporter falls back to `resource.Default`'s `service.name` if the exported Span does not have one. (#1673) +- Jaeger exporter populates Jaeger's Span Process from Resource. (#1673) +- Renamed the `LabelSet` method of `"go.opentelemetry.io/otel/sdk/resource".Resource` to `Set`. (#1692) +- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1693) +- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1693) + +### Removed + +- Removed `serviceName` parameter from Zipkin exporter and uses resource instead. (#1549) +- Removed `WithConfig` from tracer provider to avoid overriding configuration.

(#1078) +- The `go.opentelemetry.io/otel/sdk/trace` `NewBatchSpanProcessor` function no longer returns an error. + If a `nil` exporter is passed as an argument to this function, instead of it returning an error, it now returns a `BatchSpanProcessor` that handles the export of `SpanData` by not taking any action. (#1078) +- The `go.opentelemetry.io/otel/sdk/trace` `NewProvider` function to create a `Provider` no longer returns an error, instead only a `*Provider`. + This change is related to `NewBatchSpanProcessor` not returning an error which was the only error this function would return. (#1078) + +### Removed + +- Duplicate, unused API sampler interface. (#999) + Use the [`Sampler` interface](https://github.com/open-telemetry/opentelemetry-go/blob/v0.11.0/sdk/trace/sampling.go) provided by the SDK instead. +- The `grpctrace` instrumentation was moved to the `go.opentelemetry.io/contrib` repository and out of this repository. + This move includes moving the `grpc` example to the `go.opentelemetry.io/contrib` as well. (#1027) +- The `WithSpan` method of the `Tracer` interface. + The functionality this method provided was limited compared to what a user can provide themselves. + It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043) +- The `RegisterSpanProcessor` and `UnregisterSpanProcessor` functions. + These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077) +- The `oterror` package. (#1026) +- The `othttp` and `httptrace` instrumentations were moved to `go.opentelemetry.io/contrib`. (#1032) + +### Fixed + +- The `semconv.HTTPServerMetricAttributesFromHTTPRequest()` function no longer generates the high-cardinality `http.request.content.length` label. (#1031) +- Correct instrumentation version tag in Jaeger exporter. (#1037) +- The SDK span will now set an error event if the `End` method is called during a panic (i.e. it was deferred). (#1043) +- Move internally generated protobuf code from the `go.opentelemetry.io/otel` to the OTLP exporter to reduce dependency overhead. (#1050) +- The `otel-collector` example referenced outdated collector processors. (#1006) + +## [0.10.0] - 2020-07-29 + +This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages. + +### Added + +- The Zipkin exporter now has `NewExportPipeline` and `InstallNewPipeline` constructor functions to match the common pattern. + These function build a new exporter with default SDK options and register the exporter with the `global` package respectively. (#944) +- Add propagator option for gRPC instrumentation. (#986) +- The `testtrace` package now tracks the `trace.SpanKind` for each span. (#987) + +### Changed + +- Replace the `RegisterGlobal` `Option` in the Jaeger exporter with an `InstallNewPipeline` constructor function. + This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944) +- The trace (`go.opentelemetry.io/otel/exporters/trace/stdout`) and metric (`go.opentelemetry.io/otel/exporters/metric/stdout`) `stdout` exporters are now merged into a single exporter at `go.opentelemetry.io/otel/exporters/stdout`. + This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the `go.opentelemetry.io/otel` module. (#956, #963) +- Move the `go.opentelemetry.io/otel/exporters/test` test package to `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#962) +- The `go.opentelemetry.io/otel/api/kv/value` package was merged into the parent `go.opentelemetry.io/otel/api/kv` package. (#968) + - `value.Bool` was replaced with `kv.BoolValue`. + - `value.Int64` was replaced with `kv.Int64Value`. + - `value.Uint64` was replaced with `kv.Uint64Value`. + - `value.Float64` was replaced with `kv.Float64Value`. + - `value.Int32` was replaced with `kv.Int32Value`. + - `value.Uint32` was replaced with `kv.Uint32Value`. + - `value.Float32` was replaced with `kv.Float32Value`. + - `value.String` was replaced with `kv.StringValue`. + - `value.Int` was replaced with `kv.IntValue`. + - `value.Uint` was replaced with `kv.UintValue`. + - `value.Array` was replaced with `kv.ArrayValue`. +- Rename `Infer` to `Any` in the `go.opentelemetry.io/otel/api/kv` package. (#972) +- Change `othttp` to use the `httpsnoop` package to wrap the `ResponseWriter` so that optional interfaces (`http.Hijacker`, `http.Flusher`, etc.) that are implemented by the original `ResponseWriter`are also implemented by the wrapped `ResponseWriter`. (#979) +- Rename `go.opentelemetry.io/otel/sdk/metric/aggregator/test` package to `go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest`. (#980) +- Make the SDK into its own Go module called `go.opentelemetry.io/otel/sdk`. (#985) +- Changed the default trace `Sampler` from `AlwaysOn` to `ParentOrElse(AlwaysOn)`. (#989) + +### Removed + +- The `IndexedAttribute` function from the `go.opentelemetry.io/otel/api/label` package was removed in favor of `IndexedLabel` which it was synonymous with. (#970) + +### Fixed + +- Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953) +- Bump github.com/google/go-cmp from 0.5.0 to 0.5.1. (#957) +- Use `global.Handle` for span export errors in the OTLP exporter. (#946) +- Correct Go language formatting in the README documentation. (#961) +- Remove default SDK dependencies from the `go.opentelemetry.io/otel/api` package. (#977) +- Remove default SDK dependencies from the `go.opentelemetry.io/otel/instrumentation` package. (#983) +- Move documented examples for `go.opentelemetry.io/otel/instrumentation/grpctrace` interceptors into Go example tests. (#984) + +## [0.9.0] - 2020-07-20 + +### Added + +- A new Resource Detector interface is included to allow resources to be automatically detected and included. (#939) +- A Detector to automatically detect resources from an environment variable. (#939) +- Github action to generate protobuf Go bindings locally in `internal/opentelemetry-proto-gen`. (#938) +- OTLP .proto files from `open-telemetry/opentelemetry-proto` imported as a git submodule under `internal/opentelemetry-proto`. + References to `github.com/open-telemetry/opentelemetry-proto` changed to `go.opentelemetry.io/otel/internal/opentelemetry-proto-gen`. (#942) + +### Changed + +- Non-nil value `struct`s for key-value pairs will be marshalled using JSON rather than `Sprintf`. (#948) + +### Removed + +- Removed dependency on `github.com/open-telemetry/opentelemetry-collector`. (#943) + +## [0.8.0] - 2020-07-09 + +### Added + +- The `B3Encoding` type to represent the B3 encoding(s) the B3 propagator can inject. + A value for HTTP supported encodings (Multiple Header: `MultipleHeader`, Single Header: `SingleHeader`) are included. (#882) +- The `FlagsDeferred` trace flag to indicate if the trace sampling decision has been deferred. (#882) +- The `FlagsDebug` trace flag to indicate if the trace is a debug trace. (#882) +- Add `peer.service` semantic attribute. (#898) +- Add database-specific semantic attributes. (#899) +- Add semantic convention for `faas.coldstart` and `container.id`. (#909) +- Add http content size semantic conventions. (#905) +- Include `http.request_content_length` in HTTP request basic attributes. (#905) +- Add semantic conventions for operating system process resource attribute keys. (#919) +- The Jaeger exporter now has a `WithBatchMaxCount` option to specify the maximum number of spans sent in a batch. (#931) + +### Changed + +- Update `CONTRIBUTING.md` to ask for updates to `CHANGELOG.md` with each pull request. (#879) +- Use lowercase header names for B3 Multiple Headers. (#881) +- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`. + This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings. + If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882) +- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header. + Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid. + This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving. (#882) +- Extend semantic conventions for RPC. (#900) +- To match constant naming conventions in the `api/standard` package, the `FaaS*` key names are appended with a suffix of `Key`. (#920) + - `"api/standard".FaaSName` -> `FaaSNameKey` + - `"api/standard".FaaSID` -> `FaaSIDKey` + - `"api/standard".FaaSVersion` -> `FaaSVersionKey` + - `"api/standard".FaaSInstance` -> `FaaSInstanceKey` + +### Removed + +- The `FlagsUnused` trace flag is removed. + The purpose of this flag was to act as the inverse of `FlagsSampled`, the inverse of `FlagsSampled` is used instead. (#882) +- The B3 header constants (`B3SingleHeader`, `B3DebugFlagHeader`, `B3TraceIDHeader`, `B3SpanIDHeader`, `B3SampledHeader`, `B3ParentSpanIDHeader`) are removed. + If B3 header keys are needed [the authoritative OpenZipkin package constants](https://pkg.go.dev/github.com/openzipkin/zipkin-go@v0.2.2/propagation/b3?tab=doc#pkg-constants) should be used instead. (#882) + +### Fixed + +- The B3 Single Header name is now correctly `b3` instead of the previous `X-B3`. (#881) +- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882) +- The B3 propagator now propagates the debug flag. + This removes the behavior of changing the debug flag into a set sampling bit. + Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header. (#882) +- The B3 propagator now tracks "unset" sampling state (meaning "defer the decision") and does not set the `X-B3-Sampling` header when injecting. (#882) +- Bump github.com/itchyny/gojq from 0.10.3 to 0.10.4 in /tools. (#883) +- Bump github.com/opentracing/opentracing-go from v1.1.1-0.20190913142402-a7454ce5950e to v1.2.0. (#885) +- The tracing time conversion for OTLP spans is now correctly set to `UnixNano`. (#896) +- Ensure span status is not set to `Unknown` when no HTTP status code is provided as it is assumed to be `200 OK`. (#908) +- Ensure `httptrace.clientTracer` closes `http.headers` span. (#912) +- Prometheus exporter will not apply stale updates or forget inactive metrics. (#903) +- Add test for api.standard `HTTPClientAttributesFromHTTPRequest`. (#905) +- Bump github.com/golangci/golangci-lint from 1.27.0 to 1.28.1 in /tools. (#901, #913) +- Update otel-colector example to use the v0.5.0 collector. (#915) +- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922) +- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922) +- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists. + This is in accordance with OpenTelemetry semantic conventions. (#922) +- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted. (#923) +- Bump google.golang.org/api from 0.28.0 to 0.29.0 in /exporters/trace/jaeger. (#925) +- Bump github.com/itchyny/gojq from 0.10.4 to 0.11.0 in /tools. (#926) +- Bump github.com/golangci/golangci-lint from 1.28.1 to 1.28.2 in /tools. (#930) + +## [0.7.0] - 2020-06-26 + +This release implements the v0.5.0 version of the OpenTelemetry specification. + +### Added + +- The othttp instrumentation now includes default metrics. (#861) +- This CHANGELOG file to track all changes in the project going forward. +- Support for array type attributes. (#798) +- Apply transitive dependabot go.mod dependency updates as part of a new automatic Github workflow. (#844) +- Timestamps are now passed to exporters for each export. (#835) +- Add new `Accumulation` type to metric SDK to transport telemetry from `Accumulator`s to `Processor`s. + This replaces the prior `Record` `struct` use for this purpose. (#835) +- New dependabot integration to automate package upgrades. (#814) +- `Meter` and `Tracer` implementations accept instrumentation version version as an optional argument. + This instrumentation version is passed on to exporters. (#811) (#805) (#802) +- The OTLP exporter includes the instrumentation version in telemetry it exports. (#811) +- Environment variables for Jaeger exporter are supported. (#796) +- New `aggregation.Kind` in the export metric API. (#808) +- New example that uses OTLP and the collector. (#790) +- Handle errors in the span `SetName` during span initialization. (#791) +- Default service config to enable retries for retry-able failed requests in the OTLP exporter and an option to override this default. (#777) +- New `go.opentelemetry.io/otel/api/oterror` package to uniformly support error handling and definitions for the project. (#778) +- New `global` default implementation of the `go.opentelemetry.io/otel/api/oterror.Handler` interface to be used to handle errors prior to an user defined `Handler`. + There is also functionality for the user to register their `Handler` as well as a convenience function `Handle` to handle an error with this global `Handler`(#778) +- Options to specify propagators for httptrace and grpctrace instrumentation.

(#857) +- Merge otlp collector examples. (#841) +- Change the metric SDK to support cumulative, delta, and pass-through exporters directly. + With these changes, cumulative and delta specific exporters are able to request the correct kind of aggregation from the SDK. (#840) +- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812) +- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other. + All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`. + Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812) +- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`. (#812) +- Replace `AlwaysParentSample` with `ParentSample(fallback)` to match the OpenTelemetry v0.5.0 specification. (#810) +- Rename `sdk/export/metric/aggregator` to `sdk/export/metric/aggregation`. #808 +- Send configured headers with every request in the OTLP exporter, instead of just on connection creation.

(#591) +- `LabelSet` from the metric API. + This is replaced by a `[]core.KeyValue` slice. (#595) +- `Labels` from the metric API's `Meter` interface. (#595) + +### Changed + +- The metric `export.Labels` became an interface which the SDK implements and the `export` package provides a simple, immutable implementation of this interface intended for testing purposes. (#574) +- Renamed `internal/metric.Meter` to `MeterImpl`. (#580) +- Renamed `api/global/internal.obsImpl` to `asyncImpl`. (#580) + +### Fixed + +- Corrected missing return in mock span. (#582) +- Update License header for all source files to match CNCF guidelines and include a test to ensure it is present. (#586) (#596) +- Update to v0.3.0 of the OTLP in the OTLP exporter. (#588) +- Update pre-release script to be compatible between GNU and BSD based systems. (#592) +- Add a `RecordBatch` benchmark.

(#569) +- Removed unneeded allocation on empty labels in OLTP exporter. (#597) +- Update `BatchedSpanProcessor` to process the queue until no data but respect max batch size. (#599) +- Update project documentation godoc.org links to pkg.go.dev. (#602) + +## [0.3.0] - 2020-03-21 + +This is a first official beta release, which provides almost fully complete metrics, tracing, and context propagation functionality. +There is still a possibility of breaking changes. + +### Added + +- Add `Observer` metric instrument. (#474) +- Add global `Propagators` functionality to enable deferred initialization for propagators registered before the first Meter SDK is installed. (#494) +- Simplified export setup pipeline for the jaeger exporter to match other exporters. (#459) +- The zipkin trace exporter. (#495) +- The OTLP exporter to export metric and trace telemetry to the OpenTelemetry collector. (#497) (#544) (#545) +- Add `StatusMessage` field to the trace `Span`. (#524) +- Context propagation in OpenTracing bridge in terms of OpenTelemetry context propagation. (#525) +- The `Resource` type was added to the SDK. (#528) +- The global API now supports a `Tracer` and `Meter` function as shortcuts to getting a global `*Provider` and calling these methods directly. (#538) +- The metric API now defines a generic `MeterImpl` interface to support general purpose `Meter` construction. + Additionally, `SyncImpl` and `AsyncImpl` are added to support general purpose instrument construction. (#560) +- A metric `Kind` is added to represent the `MeasureKind`, `ObserverKind`, and `CounterKind`. (#560) +- Scripts to better automate the release process. (#576) + +### Changed + +- Default to to use `AlwaysSampler` instead of `ProbabilitySampler` to match OpenTelemetry specification. (#506) +- Renamed `AlwaysSampleSampler` to `AlwaysOnSampler` in the trace API. (#511) +- Renamed `NeverSampleSampler` to `AlwaysOffSampler` in the trace API. (#511) +- The `Status` field of the `Span` was changed to `StatusCode` to disambiguate with the added `StatusMessage`. (#524) +- Updated the trace `Sampler` interface conform to the OpenTelemetry specification. (#531) +- Rename metric API `Options` to `Config`. (#541) +- Rename metric `Counter` aggregator to be `Sum`. (#541) +- Unify metric options into `Option` from instrument specific options. (#541) +- The trace API's `TraceProvider` now support `Resource`s. (#545) +- Correct error in zipkin module name. (#548) +- The jaeger trace exporter now supports `Resource`s. (#551) +- Metric SDK now supports `Resource`s. + The `WithResource` option was added to configure a `Resource` on creation and the `Resource` method was added to the metric `Descriptor` to return the associated `Resource`. (#552) +- Replace `ErrNoLastValue` and `ErrEmptyDataSet` by `ErrNoData` in the metric SDK. (#557) +- The stdout trace exporter now supports `Resource`s. (#558) +- The metric `Descriptor` is now included at the API instead of the SDK. (#560) +- Replace `Ordered` with an iterator in `export.Labels`. (#567) + +### Removed + +- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452) +- The `Unregister` method for metric observers as it is not in the OpenTelemetry specification. (#560) +- `GetDescriptor` from the metric SDK. (#575) +- The `Gauge` instrument from the metric API. (#537) + +### Fixed + +- Make histogram aggregator checkpoint consistent.

(#508) +- Use `NewRoot` in the othttp plugin for public endpoints. (#513) +- Fix data race in `BatchedSpanProcessor`. (#518) +- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521 +- Use a variable-size array to represent ordered labels in maps.

(#547) +- Update OTLP exporter with latest protobuf. (#550) +- Add filters to the othttp plugin. (#556) +- Provide an implementation of the `Header*` filters that do not depend on Go 1.14. (#565) +- Encode labels once during checkpoint. + The checkpoint function is executed in a single thread so we can do the encoding lazily before passing the encoded version of labels to the exporter. + This is a cheap and quick way to avoid encoding the labels on every collection interval. (#572) +- Run coverage over all packages in `COVERAGE_MOD_DIR`. (#573) + +## [0.2.3] - 2020-03-04 + +### Added + +- `RecordError` method on `Span`s in the trace API to Simplify adding error events to spans. (#473) +- Configurable push frequency for exporters setup pipeline. (#504) + +### Changed + +- Rename the `exporter` directory to `exporters`. + The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`. + This resulted in all subsequent releases not becoming the default latest. + A consequence of this was that all `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages. + Renaming the `exporter` directory to `exporters` fixes this issue by renaming the package and therefore clearing any existing dependency tags. + Consequentially, this action also renames *all* exporter packages. (#502) + +### Removed + +- The `CorrelationContextHeader` constant in the `correlation` package is no longer exported. (#503) + +## [0.2.2] - 2020-02-27 + +### Added + +- `HTTPSupplier` interface in the propagation API to specify methods to retrieve and store a single value for a key to be associated with a carrier. (#467) +- `HTTPExtractor` interface in the propagation API to extract information from an `HTTPSupplier` into a context. (#467) +- `HTTPInjector` interface in the propagation API to inject information into an `HTTPSupplier.` (#467) +- `Config` and configuring `Option` to the propagator API. (#467) +- `Propagators` interface in the propagation API to contain the set of injectors and extractors for all supported carrier formats. (#467) +- `HTTPPropagator` interface in the propagation API to inject and extract from an `HTTPSupplier.` (#467) +- `WithInjectors` and `WithExtractors` functions to the propagator API to configure injectors and extractors to use. (#467) +- `ExtractHTTP` and `InjectHTTP` functions to apply configured HTTP extractors and injectors to a passed context. (#467) +- Histogram aggregator. (#433) +- `DefaultPropagator` function and have it return `trace.TraceContext` as the default context propagator. (#456) +- `AlwaysParentSample` sampler to the trace API. (#455) +- `WithNewRoot` option function to the trace API to specify the created span should be considered a root span. (#451) + +### Changed + +- Renamed `WithMap` to `ContextWithMap` in the correlation package. (#481) +- Renamed `FromContext` to `MapFromContext` in the correlation package. (#481) +- Move correlation context propagation to correlation package. (#479) +- Do not default to putting remote span context into links. (#480) +- `Tracer.WithSpan` updated to accept `StartOptions`. (#472) +- Renamed `MetricKind` to `Kind` to not stutter in the type usage. (#432) +- Renamed the `export` package to `metric` to match directory structure. (#432) +- Rename the `api/distributedcontext` package to `api/correlation`. (#444) +- Rename the `api/propagators` package to `api/propagation`. (#444) +- Move the propagators from the `propagators` package into the `trace` API package. (#444) +- Update `Float64Gauge`, `Int64Gauge`, `Float64Counter`, `Int64Counter`, `Float64Measure`, and `Int64Measure` metric methods to use value receivers instead of pointers. (#462) +- Moved all dependencies of tools package to a tools directory. (#466) + +### Removed + +- Binary propagators. (#467) +- NOOP propagator. (#467) + +### Fixed + +- Upgraded `github.com/golangci/golangci-lint` from `v1.21.0` to `v1.23.6` in `tools/`. (#492) +- Fix a possible nil-dereference crash (#478) +- Correct comments for `InstallNewPipeline` in the stdout exporter. (#483) +- Correct comments for `InstallNewPipeline` in the dogstatsd exporter. (#484) +- Correct comments for `InstallNewPipeline` in the prometheus exporter. (#482) +- Initialize `onError` based on `Config` in prometheus exporter. (#486) +- Correct module name in prometheus exporter README. (#475) +- Removed tracer name prefix from span names. (#430) +- Fix `aggregator_test.go` import package comment. (#431) +- Improved detail in stdout exporter. (#436) +- Fix a dependency issue (generate target should depend on stringer, not lint target) in Makefile. (#442) +- Reorders the Makefile targets within `precommit` target so we generate files and build the code before doing linting, so we can get much nicer errors about syntax errors from the compiler. (#442) +- Reword function documentation in gRPC plugin. (#446) +- Send the `span.kind` tag to Jaeger from the jaeger exporter. (#441) +- Fix `metadataSupplier` in the jaeger exporter to overwrite the header if existing instead of appending to it. (#441) +- Upgraded to Go 1.13 in CI. (#465) +- Correct opentelemetry.io URL in trace SDK documentation. (#464) +- Refactored reference counting logic in SDK determination of stale records. (#468) +- Add call to `runtime.Gosched` in instrument `acquireHandle` logic to not block the collector. (#469) + +## [0.2.1.1] - 2020-01-13 + +### Fixed + +- Use stateful batcher on Prometheus exporter fixing regression introduced in #395. (#428) + +## [0.2.1] - 2020-01-08 + +### Added + +- Global meter forwarding implementation. + This enables deferred initialization for metric instruments registered before the first Meter SDK is installed. (#392) +- Global trace forwarding implementation. + This enables deferred initialization for tracers registered before the first Trace SDK is installed. (#406) +- Standardize export pipeline creation in all exporters. (#395) +- A testing, organization, and comments for 64-bit field alignment. (#418) +- Script to tag all modules in the project. (#414) + +### Changed + +- Renamed `propagation` package to `propagators`. (#362) +- Renamed `B3Propagator` propagator to `B3`. (#362) +- Renamed `TextFormatPropagator` propagator to `TextFormat`.

(#336) +- Trace benchmark now tests both `AlwaysSample` and `NeverSample`. + Previously it was testing `AlwaysSample` twice. (#325) +- Trace benchmark now uses a `[]byte` for `TraceID` to fix failing test. (#325) +- Added a trace benchmark to test variadic functions in `setAttribute` vs `setAttributes` (#325) +- The `defaultkeys` batcher was only using the encoded label set as its map key while building a checkpoint. + This allowed distinct label sets through, but any metrics sharing a label set could be overwritten or merged incorrectly. + This was corrected. (#333) + +## [0.1.2] - 2019-11-18 + +### Fixed + +- Optimized the `simplelru` map for attributes to reduce the number of allocations. (#328) +- Removed unnecessary unslicing of parameters that are already a slice.

See the +OpenTelemetry +[community](https://github.com/open-telemetry/community#golang-sdk) +repo for information on this and other language SIGs. + +See the [public meeting +notes](https://docs.google.com/document/d/1E5e7Ld0NuU1iVvf-42tOBpu2VBBLYnh73GJuITGJTTU/edit) +for a summary description of past meetings. To request edit access, +join the meeting or get in touch on +[Slack](https://cloud-native.slack.com/archives/C01NPAXACKT). + +## Development + +You can view and edit the source code by cloning this repository: + +```sh +git clone https://github.com/open-telemetry/opentelemetry-go.git +``` + +Run `make test` to run the tests instead of `go test`. + +There are some generated files checked into the repo. To make sure +that the generated files are up-to-date, run `make` (or `make +precommit` - the `precommit` target is the default). + +The `precommit` target also fixes the formatting of the code and +checks the status of the go module files. + +Additionally, there is a `codespell` target that checks for common +typos in the code. It is not run by default, but you can run it +manually with `make codespell`. It will set up a virtual environment +in `venv` and install `codespell` there. + +If after running `make precommit` the output of `git status` contains +`nothing to commit, working tree clean` then it means that everything +is up-to-date and properly formatted. + +## Pull Requests + +### How to Send Pull Requests + +Everyone is welcome to contribute code to `opentelemetry-go` via +GitHub pull requests (PRs). + +To create a new PR, fork the project in GitHub and clone the upstream +repo: + +```sh +go get -d go.opentelemetry.io/otel +``` + +(This may print some warning about "build constraints exclude all Go +files", just ignore it.) + +This will put the project in `${GOPATH}/src/go.opentelemetry.io/otel`. You +can alternatively use `git` directly with: + +```sh +git clone https://github.com/open-telemetry/opentelemetry-go +``` + +(Note that `git clone` is *not* using the `go.opentelemetry.io/otel` name - +that name is a kind of a redirector to GitHub that `go get` can +understand, but `git` does not.) + +This would put the project in the `opentelemetry-go` directory in +current working directory. + +Enter the newly created directory and add your fork as a new remote: + +```sh +git remote add git@github.com:/opentelemetry-go +``` + +Check out a new branch, make modifications, run linters and tests, update +`CHANGELOG.md`, and push the branch to your fork: + +```sh +git checkout -b +# edit files +# update changelog +make precommit +git add -p +git commit +git push +``` + +Open a pull request against the main `opentelemetry-go` repo. Be sure to add the pull +request ID to the entry you added to `CHANGELOG.md`. + +Avoid rebasing and force-pushing to your branch to facilitate reviewing the pull request. +Rewriting Git history makes it difficult to keep track of iterations during code review. +All pull requests are squashed to a single commit upon merge to `main`. + +### How to Receive Comments + +* If the PR is not ready for review, please put `[WIP]` in the title, + tag it as `work-in-progress`, or mark it as + [`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/). +* Make sure CLA is signed and CI is clear. + +### How to Get PRs Merged + +A PR is considered **ready to merge** when: + +* It has received two qualified approvals[^1]. + + This is not enforced through automation, but needs to be validated by the + maintainer merging. + * The qualified approvals need to be from [Approver]s/[Maintainer]s + affiliated with different companies. Two qualified approvals from + [Approver]s or [Maintainer]s affiliated with the same company counts as a + single qualified approval. + * PRs introducing changes that have already been discussed and consensus + reached only need one qualified approval. The discussion and resolution + needs to be linked to the PR. + * Trivial changes[^2] only need one qualified approval. + +* All feedback has been addressed. + * All PR comments and suggestions are resolved. + * All GitHub Pull Request reviews with a status of "Request changes" have + been addressed. Another review by the objecting reviewer with a different + status can be submitted to clear the original review, or the review can be + dismissed by a [Maintainer] when the issues from the original review have + been addressed. + * Any comments or reviews that cannot be resolved between the PR author and + reviewers can be submitted to the community [Approver]s and [Maintainer]s + during the weekly SIG meeting. If consensus is reached among the + [Approver]s and [Maintainer]s during the SIG meeting the objections to the + PR may be dismissed or resolved or the PR closed by a [Maintainer]. + * Any substantive changes to the PR require existing Approval reviews be + cleared unless the approver explicitly states that their approval persists + across changes. This includes changes resulting from other feedback. + [Approver]s and [Maintainer]s can help in clearing reviews and they should + be consulted if there are any questions. + +* The PR branch is up to date with the base branch it is merging into. + * To ensure this does not block the PR, it should be configured to allow + maintainers to update it. + +* It has been open for review for at least one working day. This gives people + reasonable time to review. + * Trivial changes[^2] do not have to wait for one day and may be merged with + a single [Maintainer]'s approval. + +* All required GitHub workflows have succeeded. +* Urgent fix can take exception as long as it has been actively communicated + among [Maintainer]s. + +Any [Maintainer] can merge the PR once the above criteria have been met. + +[^1]: A qualified approval is a GitHub Pull Request review with "Approve" + status from an OpenTelemetry Go [Approver] or [Maintainer]. +[^2]: Trivial changes include: typo corrections, cosmetic non-substantive + changes, documentation corrections or updates, dependency updates, etc. + +## Design Choices + +As with other OpenTelemetry clients, opentelemetry-go follows the +[OpenTelemetry Specification](https://opentelemetry.io/docs/specs/otel). + +It's especially valuable to read through the [library +guidelines](https://opentelemetry.io/docs/specs/otel/library-guidelines). + +### Focus on Capabilities, Not Structure Compliance + +OpenTelemetry is an evolving specification, one where the desires and +use cases are clear, but the method to satisfy those uses cases are +not. + +As such, Contributions should provide functionality and behavior that +conforms to the specification, but the interface and structure is +flexible. + +It is preferable to have contributions follow the idioms of the +language rather than conform to specific API names or argument +patterns in the spec. + +For a deeper discussion, see +[this](https://github.com/open-telemetry/opentelemetry-specification/issues/165). + +## Documentation + +Each (non-internal, non-test) package must be documented using +[Go Doc Comments](https://go.dev/doc/comment), +preferably in a `doc.go` file. + +Prefer using [Examples](https://pkg.go.dev/testing#hdr-Examples) +instead of putting code snippets in Go doc comments. +In some cases, you can even create [Testable Examples](https://go.dev/blog/examples). + +You can install and run a "local Go Doc site" in the following way: + + ```sh + go install golang.org/x/pkgsite/cmd/pkgsite@latest + pkgsite + ``` + +[`go.opentelemetry.io/otel/metric`](https://pkg.go.dev/go.opentelemetry.io/otel/metric) +is an example of a very well-documented package. + +## Style Guide + +One of the primary goals of this project is that it is actually used by +developers. With this goal in mind the project strives to build +user-friendly and idiomatic Go code adhering to the Go community's best +practices. + +For a non-comprehensive but foundational overview of these best practices +the [Effective Go](https://golang.org/doc/effective_go.html) documentation +is an excellent starting place. + +As a convenience for developers building this project the `make precommit` +will format, lint, validate, and in some cases fix the changes you plan to +submit. This check will need to pass for your changes to be able to be +merged. + +In addition to idiomatic Go, the project has adopted certain standards for +implementations of common patterns. These standards should be followed as a +default, and if they are not followed documentation needs to be included as +to the reasons why. + +### Configuration + +When creating an instantiation function for a complex `type T struct`, it is +useful to allow variable number of options to be applied. However, the strong +type system of Go restricts the function design options. There are a few ways +to solve this problem, but we have landed on the following design. + +#### `config` + +Configuration should be held in a `struct` named `config`, or prefixed with +specific type name this Configuration applies to if there are multiple +`config` in the package. This type must contain configuration options. + +```go +// config contains configuration options for a thing. +type config struct { + // options ... +} +``` + +In general the `config` type will not need to be used externally to the +package and should be unexported. If, however, it is expected that the user +will likely want to build custom options for the configuration, the `config` +should be exported. Please, include in the documentation for the `config` +how the user can extend the configuration. + +It is important that internal `config` are not shared across package boundaries. +Meaning a `config` from one package should not be directly used by another. The +one exception is the API packages. The configs from the base API, eg. +`go.opentelemetry.io/otel/trace.TracerConfig` and +`go.opentelemetry.io/otel/metric.InstrumentConfig`, are intended to be consumed +by the SDK therefore it is expected that these are exported. + +When a config is exported we want to maintain forward and backward +compatibility, to achieve this no fields should be exported but should +instead be accessed by methods. + +Optionally, it is common to include a `newConfig` function (with the same +naming scheme). This function wraps any defaults setting and looping over +all options to create a configured `config`. + +```go +// newConfig returns an appropriately configured config. +func newConfig(options ...Option) config { + // Set default values for config. + config := config{/* […] */} + for _, option := range options { + config = option.apply(config) + } + // Perform any validation here. + return config +} +``` + +If validation of the `config` options is also performed this can return an +error as well that is expected to be handled by the instantiation function +or propagated to the user. + +Given the design goal of not having the user need to work with the `config`, +the `newConfig` function should also be unexported. + +#### `Option` + +To set the value of the options a `config` contains, a corresponding +`Option` interface type should be used. + +```go +type Option interface { + apply(config) config +} +``` + +Having `apply` unexported makes sure that it will not be used externally. +Moreover, the interface becomes sealed so the user cannot easily implement +the interface on its own. + +The `apply` method should return a modified version of the passed config. +This approach, instead of passing a pointer, is used to prevent the config from being allocated to the heap. + +The name of the interface should be prefixed in the same way the +corresponding `config` is (if at all). + +#### Options + +All user configurable options for a `config` must have a related unexported +implementation of the `Option` interface and an exported configuration +function that wraps this implementation. + +The wrapping function name should be prefixed with `With*` (or in the +special case of a boolean options `Without*`) and should have the following +function signature. + +```go +func With*(…) Option { … } +``` + +##### `bool` Options + +```go +type defaultFalseOption bool + +func (o defaultFalseOption) apply(c config) config { + c.Bool = bool(o) + return c +} + +// WithOption sets a T to have an option included. +func WithOption() Option { + return defaultFalseOption(true) +} +``` + +```go +type defaultTrueOption bool + +func (o defaultTrueOption) apply(c config) config { + c.Bool = bool(o) + return c +} + +// WithoutOption sets a T to have Bool option excluded. +func WithoutOption() Option { + return defaultTrueOption(false) +} +``` + +##### Declared Type Options + +```go +type myTypeOption struct { + MyType MyType +} + +func (o myTypeOption) apply(c config) config { + c.MyType = o.MyType + return c +} + +// WithMyType sets T to have include MyType. +func WithMyType(t MyType) Option { + return myTypeOption{t} +} +``` + +##### Functional Options + +```go +type optionFunc func(config) config + +func (fn optionFunc) apply(c config) config { + return fn(c) +} + +// WithMyType sets t as MyType. +func WithMyType(t MyType) Option { + return optionFunc(func(c config) config { + c.MyType = t + return c + }) +} +``` + +#### Instantiation + +Using this configuration pattern to configure instantiation with a `NewT` +function. + +```go +func NewT(options ...Option) T {…} +``` + +Any required parameters can be declared before the variadic `options`. + +#### Dealing with Overlap + +Sometimes there are multiple complex `struct` that share common +configuration and also have distinct configuration. To avoid repeated +portions of `config`s, a common `config` can be used with the union of +options being handled with the `Option` interface. + +For example. + +```go +// config holds options for all animals. +type config struct { + Weight float64 + Color string + MaxAltitude float64 +} + +// DogOption apply Dog specific options. +type DogOption interface { + applyDog(config) config +} + +// BirdOption apply Bird specific options. +type BirdOption interface { + applyBird(config) config +} + +// Option apply options for all animals. +type Option interface { + BirdOption + DogOption +} + +type weightOption float64 + +func (o weightOption) applyDog(c config) config { + c.Weight = float64(o) + return c +} + +func (o weightOption) applyBird(c config) config { + c.Weight = float64(o) + return c +} + +func WithWeight(w float64) Option { return weightOption(w) } + +type furColorOption string + +func (o furColorOption) applyDog(c config) config { + c.Color = string(o) + return c +} + +func WithFurColor(c string) DogOption { return furColorOption(c) } + +type maxAltitudeOption float64 + +func (o maxAltitudeOption) applyBird(c config) config { + c.MaxAltitude = float64(o) + return c +} + +func WithMaxAltitude(a float64) BirdOption { return maxAltitudeOption(a) } + +func NewDog(name string, o ...DogOption) Dog {…} +func NewBird(name string, o ...BirdOption) Bird {…} +``` + +### Interfaces + +To allow other developers to better comprehend the code, it is important +to ensure it is sufficiently documented. One simple measure that contributes +to this aim is self-documenting by naming method parameters. Therefore, +where appropriate, methods of every exported interface type should have +their parameters appropriately named. + +#### Interface Stability + +All exported stable interfaces that include the following warning in their +documentation are allowed to be extended with additional methods. + +> Warning: methods may be added to this interface in minor releases. + +These interfaces are defined by the OpenTelemetry specification and will be +updated as the specification evolves. + +Otherwise, stable interfaces MUST NOT be modified. + +#### How to Change Specification Interfaces + +When an API change must be made, we will update the SDK with the new method one +release before the API change. This will allow the SDK one version before the +API change to work seamlessly with the new API. + +If an incompatible version of the SDK is used with the new API the application +will fail to compile. + +#### How Not to Change Specification Interfaces + +We have explored using a v2 of the API to change interfaces and found that there +was no way to introduce a v2 and have it work seamlessly with the v1 of the API. +Problems happened with libraries that upgraded to v2 when an application did not, +and would not produce any telemetry. + +More detail of the approaches considered and their limitations can be found in +the [Use a V2 API to evolve interfaces](https://github.com/open-telemetry/opentelemetry-go/issues/3920) +issue. + +#### How to Change Other Interfaces + +If new functionality is needed for an interface that cannot be changed it MUST +be added by including an additional interface. That added interface can be a +simple interface for the specific functionality that you want to add or it can +be a super-set of the original interface. For example, if you wanted to a +`Close` method to the `Exporter` interface: + +```go +type Exporter interface { + Export() +} +``` + +A new interface, `Closer`, can be added: + +```go +type Closer interface { + Close() +} +``` + +Code that is passed the `Exporter` interface can now check to see if the passed +value also satisfies the new interface. E.g. + +```go +func caller(e Exporter) { + /* ... */ + if c, ok := e.(Closer); ok { + c.Close() + } + /* ... */ +} +``` + +Alternatively, a new type that is the super-set of an `Exporter` can be created. + +```go +type ClosingExporter struct { + Exporter + Close() +} +``` + +This new type can be used similar to the simple interface above in that a +passed `Exporter` type can be asserted to satisfy the `ClosingExporter` type +and the `Close` method called. + +This super-set approach can be useful if there is explicit behavior that needs +to be coupled with the original type and passed as a unified type to a new +function, but, because of this coupling, it also limits the applicability of +the added functionality. If there exist other interfaces where this +functionality should be added, each one will need their own super-set +interfaces and will duplicate the pattern. For this reason, the simple targeted +interface that defines the specific functionality should be preferred. + +### Testing + +The tests should never leak goroutines. + +Use the term `ConcurrentSafe` in the test name when it aims to verify the +absence of race conditions. + +### Internal packages + +The use of internal packages should be scoped to a single module. A sub-module +should never import from a parent internal package. This creates a coupling +between the two modules where a user can upgrade the parent without the child +and if the internal package API has changed it will fail to upgrade[^3]. + +There are two known exceptions to this rule: + +- `go.opentelemetry.io/otel/internal/global` + - This package manages global state for all of opentelemetry-go. It needs to + be a single package in order to ensure the uniqueness of the global state. +- `go.opentelemetry.io/otel/internal/baggage` + - This package provides values in a `context.Context` that need to be + recognized by `go.opentelemetry.io/otel/baggage` and + `go.opentelemetry.io/otel/bridge/opentracing` but remain private. + +If you have duplicate code in multiple modules, make that code into a Go +template stored in `go.opentelemetry.io/otel/internal/shared` and use [gotmpl] +to render the templates in the desired locations.

This project allows you to do just that for applications written in +Go. There are two steps to this process: instrument your application, and +configure an exporter. + +### Instrumentation + +To start capturing distributed traces and metric events from your application +it first needs to be instrumented. The easiest way to do this is by using an +instrumentation library for your code. Be sure to check out [the officially +supported instrumentation +libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation). + +If you need to extend the telemetry an instrumentation library provides or want +to build your own instrumentation for your application directly you will need +to use the +[Go otel](https://pkg.go.dev/go.opentelemetry.io/otel) +package. The included [examples](./example/) are a good way to see some +practical uses of this process. + +### Export + +Now that your application is instrumented to collect telemetry, it needs an +export pipeline to send that telemetry to an observability platform. + +All officially supported exporters for the OpenTelemetry project are contained in the [exporters directory](./exporters). + +| Exporter | Metrics | Traces | +|---------------------------------------|:-------:|:------:| +| [OTLP](./exporters/otlp/) | ✓ | ✓ | +| [Prometheus](./exporters/prometheus/) | ✓ | | +| [stdout](./exporters/stdout/) | ✓ | ✓ | +| [Zipkin](./exporters/zipkin/) | | ✓ | + +## Contributing + +See the [contributing documentation](CONTRIBUTING.md). diff --git a/vendor/go.opentelemetry.io/otel/RELEASING.md b/vendor/go.opentelemetry.io/otel/RELEASING.md new file mode 100644 index 000000000..82ce3ee46 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/RELEASING.md @@ -0,0 +1,139 @@ +# Release Process + +## Semantic Convention Generation + +New versions of the [OpenTelemetry Semantic Conventions] mean new versions of the `semconv` package need to be generated. +The `semconv-generate` make target is used for this. + +1.

The public API SHOULD NOT be considered stable. + + * Mature modules for which we guarantee a stable public API will be versioned + with a major version greater than `v0`. + * The decision to make a module stable will be made on a case-by-case + basis by the maintainers of this project. + * Experimental modules will start their versioning at `v0.0.0` and will + increment their minor version when backwards incompatible changes are + released and increment their patch version when backwards compatible + changes are released. + * All stable modules that use the same major version number will use the + same entire version number. + * Stable modules may be released with an incremented minor or patch + version even though that module has not been changed, but rather so + that it will remain at the same version as other stable modules that + did undergo change. + * When an experimental module becomes stable a new stable module version + will be released and will include this now stable module. The new + stable module version will be an increment of the minor version number + and will be applied to all existing stable modules as well as the newly + stable module being released. +* Versioning of the associated [contrib + repository](https://github.com/open-telemetry/opentelemetry-go-contrib) of + this project will be idiomatic of a Go project using [Go + modules](https://github.com/golang/go/wiki/Modules). + * [Semantic import + versioning](https://github.com/golang/go/wiki/Modules#semantic-import-versioning) + will be used. + * Versions will comply with [semver 2.0](https://semver.org/spec/v2.0.0.html). + * If a module is version `v2` or higher, the + major version of the module must be included as a `/vN` at the end of the + module paths used in `go.mod` files (e.g., `module + go.opentelemetry.io/contrib/instrumentation/host/v2`, `require + go.opentelemetry.io/contrib/instrumentation/host/v2 v2.0.1`) and in the + package import path (e.g., `import + "go.opentelemetry.io/contrib/instrumentation/host/v2"`). This includes + the paths used in `go get` commands (e.g., `go get + go.opentelemetry.io/contrib/instrumentation/host/v2@v2.0.1`. Note there + is both a `/v2` and a `@v2.0.1` in that example. One way to think about + it is that the module name now includes the `/v2`, so include `/v2` + whenever you are using the module name). + * If a module is version `v0` or `v1`, do not include the major version + in either the module path or the import path. + * In addition to public APIs, telemetry produced by stable instrumentation + will remain stable and backwards compatible. This is to avoid breaking + alerts and dashboard. + * Modules will be used to encapsulate instrumentation, detectors, exporters, + propagators, and any other independent sets of related components. + * Experimental modules still under active development will be versioned at + `v0` to imply the stability guarantee defined by + [semver](https://semver.org/spec/v2.0.0.html#spec-item-4). + + > Major version zero (0.y.z) is for initial development.

Instead + the only change that will have been included is to have updated that + modules dependency on this project's stable APIs. + * When an experimental module in contrib becomes stable a new stable + module version will be released and will include this now stable + module. The new stable module version will be an increment of the minor + version number and will be applied to all existing stable contrib + modules, this project's modules, and the newly stable module being + released. + * Contrib modules will be kept up to date with this project's releases. + * Due to the dependency contrib modules will implicitly have on this + project's modules the release of stable contrib modules to match the + released version number will be staggered after this project's release. + There is no explicit time guarantee for how long after this projects + release the contrib release will be. Effort should be made to keep them + as close in time as possible. + * No additional stable release in this project can be made until the + contrib repository has a matching stable release. + * No release can be made in the contrib repository after this project's + stable release except for a stable release of the contrib repository. +* GitHub releases will be made for all releases. +* Go modules will be made available at Go package mirrors. + +## Example Versioning Lifecycle + +To better understand the implementation of the above policy the following +example is provided. This project is simplified to include only the following +modules and their versions: + +* `otel`: `v0.14.0` +* `otel/trace`: `v0.14.0` +* `otel/metric`: `v0.14.0` +* `otel/baggage`: `v0.14.0` +* `otel/sdk/trace`: `v0.14.0` +* `otel/sdk/metric`: `v0.14.0` + +These modules have been developed to a point where the `otel/trace`, +`otel/baggage`, and `otel/sdk/trace` modules have reached a point that they +should be considered for a stable release. The `otel/metric` and +`otel/sdk/metric` are still under active development and the `otel` module +depends on both `otel/trace` and `otel/metric`. + +The `otel` package is refactored to remove its dependencies on `otel/metric` so +it can be released as stable as well. With that done the following release +candidates are made: + +* `otel`: `v1.0.0-RC1` +* `otel/trace`: `v1.0.0-RC1` +* `otel/baggage`: `v1.0.0-RC1` +* `otel/sdk/trace`: `v1.0.0-RC1` + +The `otel/metric` and `otel/sdk/metric` modules remain at `v0.14.0`. + +A few minor issues are discovered in the `otel/trace` package. These issues are +resolved with some minor, but backwards incompatible, changes and are released +as a second release candidate: + +* `otel`: `v1.0.0-RC2` +* `otel/trace`: `v1.0.0-RC2` +* `otel/baggage`: `v1.0.0-RC2` +* `otel/sdk/trace`: `v1.0.0-RC2` + +Notice that all module version numbers are incremented to adhere to our +versioning policy. + +After these release candidates have been evaluated to satisfaction, they are +released as version `v1.0.0`. + +* `otel`: `v1.0.0` +* `otel/trace`: `v1.0.0` +* `otel/baggage`: `v1.0.0` +* `otel/sdk/trace`: `v1.0.0` + +Since both the `go` utility and the Go module system support [the semantic +versioning definition of +precedence](https://semver.org/spec/v2.0.0.html#spec-item-11), this release +will correctly be interpreted as the successor to the previous release +candidates. + +Active development of this project continues. The `otel/metric` module now has +backwards incompatible changes to its API that need to be released and the +`otel/baggage` module has a minor bug fix that needs to be released. The +following release is made: + +* `otel`: `v1.0.1` +* `otel/trace`: `v1.0.1` +* `otel/metric`: `v0.15.0` +* `otel/baggage`: `v1.0.1` +* `otel/sdk/trace`: `v1.0.1` +* `otel/sdk/metric`: `v0.15.0` + +Notice that, again, all stable module versions are incremented in unison and +the `otel/sdk/metric` package, which depends on the `otel/metric` package, also +bumped its version. This bump of the `otel/sdk/metric` package makes sense +given their coupling, though it is not explicitly required by our versioning +policy. + +As we progress, the `otel/metric` and `otel/sdk/metric` packages have reached a +point where they should be evaluated for stability. The `otel` module is +reintegrated with the `otel/metric` package and the following release is made: + +* `otel`: `v1.1.0-RC1` +* `otel/trace`: `v1.1.0-RC1` +* `otel/metric`: `v1.1.0-RC1` +* `otel/baggage`: `v1.1.0-RC1` +* `otel/sdk/trace`: `v1.1.0-RC1` +* `otel/sdk/metric`: `v1.1.0-RC1` + +All the modules are evaluated and determined to a viable stable release. They +are then released as version `v1.1.0` (the minor version is incremented to +indicate the addition of new signal). + +* `otel`: `v1.1.0` +* `otel/trace`: `v1.1.0` +* `otel/metric`: `v1.1.0` +* `otel/baggage`: `v1.1.0` +* `otel/sdk/trace`: `v1.1.0` +* `otel/sdk/metric`: `v1.1.0` diff --git a/vendor/go.opentelemetry.io/otel/attribute/doc.go b/vendor/go.opentelemetry.io/otel/attribute/doc.go new file mode 100644 index 000000000..dafe7424d --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/doc.go @@ -0,0 +1,16 @@ +// Copyright The OpenTelemetry 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 attribute provides key and value attributes. +package attribute // import "go.opentelemetry.io/otel/attribute" diff --git a/vendor/go.opentelemetry.io/otel/attribute/encoder.go b/vendor/go.opentelemetry.io/otel/attribute/encoder.go new file mode 100644 index 000000000..fe2bc5766 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/encoder.go @@ -0,0 +1,146 @@ +// Copyright The OpenTelemetry 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 attribute // import "go.opentelemetry.io/otel/attribute" + +import ( + "bytes" + "sync" + "sync/atomic" +) + +type ( + // Encoder is a mechanism for serializing an attribute set into a specific + // string representation that supports caching, to avoid repeated + // serialization.

See [go.opentelemetry.io/otel/sdk/metric] for the official +OpenTelemetry implementation of this API. + +All measurements made with this package are made via instruments. These +instruments are created by a [Meter] which itself is created by a +[MeterProvider]. Applications need to accept a [MeterProvider] implementation +as a starting point when instrumenting. This can be done directly, or by using +the OpenTelemetry global MeterProvider via [GetMeterProvider]. Using an +appropriately named [Meter] from the accepted [MeterProvider], instrumentation +can then be built from the [Meter]'s instruments. + +# Instruments + +Each instrument is designed to make measurements of a particular type. Broadly, +all instruments fall into two overlapping logical categories: asynchronous or +synchronous, and int64 or float64. + +All synchronous instruments ([Int64Counter], [Int64UpDownCounter], +[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and +[Float64Histogram]) are used to measure the operation and performance of source +code during the source code execution. These instruments only make measurements +when the source code they instrument is run. + +All asynchronous instruments ([Int64ObservableCounter], +[Int64ObservableUpDownCounter], [Int64ObservableGauge], +[Float64ObservableCounter], [Float64ObservableUpDownCounter], and +[Float64ObservableGauge]) are used to measure metrics outside of the execution +of source code. They are said to make "observations" via a callback function +called once every measurement collection cycle. + +Each instrument is also grouped by the value type it measures. Either int64 or +float64. The value being measured will dictate which instrument in these +categories to use. + +Outside of these two broad categories, instruments are described by the +function they are designed to serve. All Counters ([Int64Counter], +[Float64Counter], [Int64ObservableCounter], and [Float64ObservableCounter]) are +designed to measure values that never decrease in value, but instead only +incrementally increase in value. UpDownCounters ([Int64UpDownCounter], +[Float64UpDownCounter], [Int64ObservableUpDownCounter], and +[Float64ObservableUpDownCounter]) on the other hand, are designed to measure +values that can increase and decrease. When more information needs to be +conveyed about all the synchronous measurements made during a collection cycle, +a Histogram ([Int64Histogram] and [Float64Histogram]) should be used. Finally, +when just the most recent measurement needs to be conveyed about an +asynchronous measurement, a Gauge ([Int64ObservableGauge] and +[Float64ObservableGauge]) should be used. + +See the [OpenTelemetry documentation] for more information about instruments +and their intended use. + +# Measurements + +Measurements are made by recording values and information about the values with +an instrument. How these measurements are recorded depends on the instrument. + +Measurements for synchronous instruments ([Int64Counter], [Int64UpDownCounter], +[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and +[Float64Histogram]) are recorded using the instrument methods directly. All +counter instruments have an Add method that is used to measure an increment +value, and all histogram instruments have a Record method to measure a data +point. + +Asynchronous instruments ([Int64ObservableCounter], +[Int64ObservableUpDownCounter], [Int64ObservableGauge], +[Float64ObservableCounter], [Float64ObservableUpDownCounter], and +[Float64ObservableGauge]) record measurements within a callback function. The +callback is registered with the Meter which ensures the callback is called once +per collection cycle. A callback can be registered two ways: during the +instrument's creation using an option, or later using the RegisterCallback +method of the [Meter] that created the instrument. + +If the following criteria are met, an option ([WithInt64Callback] or +[WithFloat64Callback]) can be used during the asynchronous instrument's +creation to register a callback ([Int64Callback] or [Float64Callback], +respectively): + + - The measurement process is known when the instrument is created + - Only that instrument will make a measurement within the callback + - The callback never needs to be unregistered + +If the criteria are not met, use the RegisterCallback method of the [Meter] that +created the instrument to register a [Callback]. + +# API Implementations + +This package does not conform to the standard Go versioning policy, all of its +interfaces may have methods added to them without a package major version bump. +This non-standard API evolution could surprise an uninformed implementation +author. They could unknowingly build their implementation in a way that would +result in a runtime panic for their users that update to the new API. + +The API is designed to help inform an instrumentation author about this +non-standard API evolution. It requires them to choose a default behavior for +unimplemented interface methods. There are three behavior choices they can +make: + + - Compilation failure + - Panic + - Default to another implementation + +All interfaces in this API embed a corresponding interface from +[go.opentelemetry.io/otel/metric/embedded]. If an author wants the default +behavior of their implementations to be a compilation failure, signaling to +their users they need to update to the latest version of that implementation, +they need to embed the corresponding interface from +[go.opentelemetry.io/otel/metric/embedded] in their implementation. For +example, + + import "go.opentelemetry.io/otel/metric/embedded" + + type MeterProvider struct { + embedded.MeterProvider + // ... + } + +If an author wants the default behavior of their implementations to a panic, +they need to embed the API interface directly. + + import "go.opentelemetry.io/otel/metric" + + type MeterProvider struct { + metric.MeterProvider + // ... + } + +This is not a recommended behavior as it could lead to publishing packages that +contain runtime panics when users update other package that use newer versions +of [go.opentelemetry.io/otel/metric]. + +Finally, an author can embed another implementation in theirs. The embedded +implementation will be used for methods not defined by the author. For example, +an author who wants to default to silently dropping the call can use +[go.opentelemetry.io/otel/metric/noop]: + + import "go.opentelemetry.io/otel/metric/noop" + + type MeterProvider struct { + noop.MeterProvider + // ... + } + +It is strongly recommended that authors only embed +[go.opentelemetry.io/otel/metric/noop] if they choose this default behavior. +That implementation is the only one OpenTelemetry authors can guarantee will +fully implement all the API interfaces when a user updates their API. + +[OpenTelemetry documentation]: https://opentelemetry.io/docs/concepts/signals/metrics/ +[GetMeterProvider]: https://pkg.go.dev/go.opentelemetry.io/otel#GetMeterProvider +*/ +package metric // import "go.opentelemetry.io/otel/metric" diff --git a/vendor/go.opentelemetry.io/otel/metric/embedded/embedded.go b/vendor/go.opentelemetry.io/otel/metric/embedded/embedded.go new file mode 100644 index 000000000..ae0bdbd2e --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/metric/embedded/embedded.go @@ -0,0 +1,234 @@ +// Copyright The OpenTelemetry 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 embedded provides interfaces embedded within the [OpenTelemetry +// metric API]. +// +// Implementers of the [OpenTelemetry metric API] can embed the relevant type +// from this package into their implementation directly.
