Keep it small & fast. + * CEL evaluates in linear time, is mutation free, and not Turing-complete. + This limitation is a feature of the language design, which allows the + implementation to evaluate orders of magnitude faster than equivalently + sandboxed JavaScript. +2. Make it extensible. + * CEL is designed to be embedded in applications, and allows for + extensibility via its context which allows for functions and data to be + provided by the software that embeds it. +3. Developer-friendly. + * The language is approachable to developers. The initial spec was based + on the experience of developing Firebase Rules and usability testing + many prior iterations. + * The library itself and accompanying toolings should be easy to adopt by + teams that seek to integrate CEL into their platforms. + +The required components of a system that supports CEL are: + +* The textual representation of an expression as written by a developer. It is + of similar syntax to expressions in C/C++/Java/JavaScript +* A representation of the program's abstract syntax tree (AST). +* A compiler library that converts the textual representation to the binary + representation. This can be done ahead of time (in the control plane) or + just before evaluation (in the data plane). +* A context containing one or more typed variables, often protobuf messages. + Most use-cases will use `attribute_context.proto` +* An evaluator library that takes the binary format in the context and + produces a result, usually a Boolean. + +For use cases which require persistence or cross-process communcation, it is +highly recommended to serialize the type-checked expression as a protocol +buffer.

the **NYTimes/gziphandler** community, as well as steps to reporting unacceptable behavior. We are committed to providing a welcoming and inspiring community for all and expect our code of conduct to be honored. Anyone who violates this code of conduct may be banned from the community. + +Our open source community strives to: + +* **Be friendly and patient.** +* **Be welcoming**: We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability. +* **Be considerate**: Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we're a world-wide community, so you might not be communicating in someone else's primary language. +* **Be respectful**: Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one. +* **Be careful in the words that we choose**: we are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren't acceptable. +* **Try to understand why we disagree**: Disagreements, both social and technical, happen all the time. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of our community comes from its diversity, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes. + +## Definitions + +Harassment includes, but is not limited to: + +- Offensive comments related to gender, gender identity and expression, sexual orientation, disability, mental illness, neuro(a)typicality, physical appearance, body size, race, age, regional discrimination, political or religious affiliation +- Unwelcome comments regarding a person’s lifestyle choices and practices, including those related to food, health, parenting, drugs, and employment +- Deliberate misgendering. This includes deadnaming or persistently using a pronoun that does not correctly reflect a person's gender identity. You must address people by the name they give you when not addressing them by their username or handle +- Physical contact and simulated physical contact (eg, textual descriptions like “*hug*” or “*backrub*”) without consent or after a request to stop +- Threats of violence, both physical and psychological +- Incitement of violence towards any individual, including encouraging a person to commit suicide or to engage in self-harm +- Deliberate intimidation +- Stalking or following +- Harassing photography or recording, including logging online activity for harassment purposes +- Sustained disruption of discussion +- Unwelcome sexual attention, including gratuitous or off-topic sexual images or behaviour +- Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others +- Continued one-on-one communication after requests to cease +- Deliberate “outing” of any aspect of a person’s identity without their consent except as necessary to protect others from intentional abuse +- Publication of non-harassing private communication + +Our open source community prioritizes marginalized people’s safety over privileged people’s comfort.

It's widely used to build languages, tools, and frameworks. +From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface +(or visitor) that makes it easy to respond to the recognition of phrases of interest. + +# Go Runtime + +At version 4.11.x and prior, the Go runtime was not properly versioned for go modules. After this point, the runtime +source code to be imported was held in the `runtime/Go/antlr/v4` directory, and the go.mod file was updated to reflect the version of +ANTLR4 that it is compatible with (I.E. uses the /v4 path). + +However, this was found to be problematic, as it meant that with the runtime embedded so far underneath the root +of the repo, the `go get` and related commands could not properly resolve the location of the go runtime source code. +This meant that the reference to the runtime in your `go.mod` file would refer to the correct source code, but would not +list the release tag such as @4.12.0 - this was confusing, to say the least. + +As of 4.12.1, the runtime is now available as a go module in its own repo, and can be imported as `github.com/antlr4-go/antlr` +(the go get command should also be used with this path). See the main documentation for the ANTLR4 project for more information, +which is available at [ANTLR docs]. The documentation for using the Go runtime is available at [Go runtime docs]. + +This means that if you are using the source code without modules, you should also use the source code in the [new repo]. +Though we highly recommend that you use go modules, as they are now idiomatic for Go. + +I am aware that this change will prove Hyrum's Law, but am prepared to live with it for the common good. + +Go runtime author: [Jim Idle] jimi@idle.ws + +# Code Generation + +ANTLR supports the generation of code in a number of [target languages], and the generated code is supported by a +runtime library, written specifically to support the generated code in the target language. This library is the +runtime for the Go target. + +To generate code for the go target, it is generally recommended to place the source grammar files in a package of +their own, and use the `.sh` script method of generating code, using the go generate directive. In that same directory +it is usual, though not required, to place the antlr tool that should be used to generate the code. That does mean +that the antlr tool JAR file will be checked in to your source code control though, so you are, of course, free to use any other +way of specifying the version of the ANTLR tool to use, such as aliasing in `.zshrc` or equivalent, or a profile in +your IDE, or configuration in your CI system. Checking in the jar does mean that it is easy to reproduce the build as +it was at any point in its history. + +Here is a general/recommended template for an ANTLR based recognizer in Go: + + . + ├── parser + │ ├── mygrammar.g4 + │ ├── antlr-4.12.1-complete.jar + │ ├── generate.go + │ └── generate.sh + ├── parsing - generated code goes here + │ └── error_listeners.go + ├── go.mod + ├── go.sum + ├── main.go + └── main_test.go + +Make sure that the package statement in your grammar file(s) reflects the go package the generated code will exist in. + +The generate.go file then looks like this: + + package parser + + //go:generate ./generate.sh + +And the generate.sh file will look similar to this: + + #!/bin/sh + + alias antlr4='java -Xmx500M -cp "./antlr4-4.12.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool' + antlr4 -Dlanguage=Go -no-visitor -package parsing *.g4 + +depending on whether you want visitors or listeners or any other ANTLR options. Not that another option here +is to generate the code into a + +From the command line at the root of your source package (location of go.mo)d) you can then simply issue the command: + + go generate ./... + +Which will generate the code for the parser, and place it in the parsing package. You can then use the generated code +by importing the parsing package. + +There are no hard and fast rules on this. It is just a recommendation.

If +// the union of these alternative subsets is a singleton, then no amount of +// further lookahead will help us. We will always pick that alternative. If, +// however, there is more than one alternative, then we are uncertain which +// alternative to predict and must continue looking for resolution. We may +// or may not discover an ambiguity in the future, even if there are no +// conflicting subsets this round. +// +// The biggest sin is to terminate early because it means we've made a +// decision but were uncertain as to the eventual outcome. We haven't used +// enough lookahead. On the other hand, announcing a conflict too late is no +// big deal; you will still have the conflict. It's just inefficient. It +// might even look until the end of file. +// +// No special consideration for semantic predicates is required because +// predicates are evaluated on-the-fly for full LL prediction, ensuring that +// no configuration contains a semantic context during the termination +// check. +// +// # Conflicting Configs +// +// Two configurations: +// +// (s, i, x) and (s, j, x') +// +// conflict when i != j but x = x'. Because we merge all +// (s, i, _) configurations together, that means that there are at +// most n configurations associated with state s for +// n possible alternatives in the decision. The merged stacks +// complicate the comparison of configuration contexts x and x'. +// +// Sam checks to see if one is a subset of the other by calling +// merge and checking to see if the merged result is either x or x'. +// If the x associated with lowest alternative i +// is the superset, then i is the only possible prediction since the +// others resolve to min(i) as well. However, if x is +// associated with j > i then at least one stack configuration for +// j is not in conflict with alternative i. The algorithm +// should keep going, looking for more lookahead due to the uncertainty. +// +// For simplicity, I'm doing an equality check between x and +// x', which lets the algorithm continue to consume lookahead longer +// than necessary.

+// You can insert stuff, replace, and delete chunks. Note that the operations +// are done lazily--only if you convert the buffer to a {@link String} with +// {@link TokenStream#getText()}. This is very efficient because you are not +// moving data around all the time. As the buffer of tokens is converted to +// strings, the {@link #getText()} method(s) scan the input token stream and +// check to see if there is an operation at the current index. If so, the +// operation is done and then normal {@link String} rendering continues on the +// buffer. This is like having multiple Turing machine instruction streams +// (programs) operating on a single input tape. :)

+//

+ +// This rewriter makes no modifications to the token stream. It does not ask the +// stream to fill itself up nor does it advance the input cursor. The token +// stream {@link TokenStream#index()} will return the same value before and +// after any {@link #getText()} call.

+ +//

+// The rewriter only works on tokens that you have in the buffer and ignores the +// current input cursor. If you are buffering tokens on-demand, calling +// {@link #getText()} halfway through the input will only do rewrites for those +// tokens in the first half of the file.

+ +//

+// Since the operations are done lazily at {@link #getText}-time, operations do +// not screw up the token index values. That is, an insert operation at token +// index {@code i} does not change the index values for tokens +// {@code i}+1..n-1.

+ +//

+// Because operations never actually alter the buffer, you may always get the +// original token stream back without undoing anything. Since the instructions +// are queued up, you can easily simulate transactions and roll back any changes +// if there is an error just by removing instructions. For example,

+ +// 
+// CharStream input = new ANTLRFileStream("input");
+// TLexer lex = new TLexer(input);
+// CommonTokenStream tokens = new CommonTokenStream(lex);
+// T parser = new T(tokens);
+// TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+// parser.startRule();
+//
+ +//

+// Then in the rules, you can execute (assuming rewriter is visible):

+ +// 
+// Token t,u;
+// ...
+// rewriter.insertAfter(t, "text to put after t");}
+// rewriter.insertAfter(u, "text after u");}
+// System.out.println(rewriter.getText());
+//
+ +//

+// You can also have multiple "instruction streams" and get multiple rewrites +// from a single pass over the input. Just name the instruction streams and use +// that name again when printing the buffer. This could be useful for generating +// a C file and also its header file--all from the same buffer:

+ +// 
+// rewriter.insertAfter("pass1", t, "text to put after t");}
+// rewriter.insertAfter("pass2", u, "text after u");}
+// System.out.println(rewriter.getText("pass1"));
+// System.out.println(rewriter.getText("pass2"));
+//
+ +//

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.

With gob, you could just send it. With goprotobuf, you need to make a parallel struct. +Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions. + + - nullable, if false, a field is generated without a pointer (see warning below). + - embed, if true, the field is generated as an embedded field. + - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128 + - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames. + - casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums. + - castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps. + - castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps. + +Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset. + +Let us look at: + + github.com/gogo/protobuf/test/example/example.proto + +for a quicker overview. + +The following message: + + package test; + + import "github.com/gogo/protobuf/gogoproto/gogo.proto"; + + message A { + optional string Description = 1 [(gogoproto.nullable) = false]; + optional int64 Number = 2 [(gogoproto.nullable) = false]; + optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false]; + } + +Will generate a go struct which looks a lot like this: + + type A struct { + Description string + Number int64 + Id github_com_gogo_protobuf_test_custom.Uuid + } + +You will see there are no pointers, since all fields are non-nullable. +You will also see a custom type which marshals to a string. +Be warned it is your responsibility to test your custom types thoroughly. +You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods. + +Next we will embed the message A in message B. + + message B { + optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true]; + repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false]; + } + +See below that A is embedded in B. + + type B struct { + A + G []github_com_gogo_protobuf_test_custom.Uint128 + } + +Also see the repeated custom type. + + type Uint128 [2]uint64 + +Next we will create a custom name for one of our fields. + + message C { + optional int64 size = 1 [(gogoproto.customname) = "MySize"]; + } + +See below that the field's name is MySize and not Size. + + type C struct { + MySize *int64 + } + +The is useful when having a protocol buffer message with a field name which conflicts with a generated method. +As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error. +Using customname you can fix this error without changing the field name. +This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable. + +Gogoprotobuf also has some more subtle changes, these could be changed back: + + - the generated package name for imports do not have the extra /filename.pb, + but are actually the imports specified in the .proto file. + +Gogoprotobuf also has lost some features which should be brought back with time: + + - Marshalling and unmarshalling with reflect and without the unsafe package, + this requires work in pointer_reflect.go + +Why does nullable break protocol buffer specifications: + +The protocol buffer specification states, somewhere, that you should be able to tell whether a +field is set or unset. With the option nullable=false this feature is lost, +since your non-nullable fields will always be set. It can be seen as a layer on top of +protocol buffers, where before and after marshalling all non-nullable fields are set +and they cannot be unset. + +Goprotobuf Compatibility: + +Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers. +Gogoprotobuf generates the same code as goprotobuf if no extensions are used. +The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf: + + - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto. + - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix + - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method. + - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face + - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method. + - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension + - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields. + - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway). + +Less Typing and Peace of Mind is explained in their specific plugin folders godoc: + + - github.com/gogo/protobuf/plugin/ + +If you do not use any of these extension the code that is generated +will be the same as if goprotobuf has generated it. + +The most complete way to see examples is to look at + + github.com/gogo/protobuf/test/thetest.proto + +Gogoprototest is a seperate project, +because we want to keep gogoprotobuf independent of goprotobuf, +but we still want to test it thoroughly. + +*/ +package gogoproto diff --git a/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go b/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go new file mode 100644 index 00000000..1e91766a --- /dev/null +++ b/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go @@ -0,0 +1,874 @@ +// Code generated by protoc-gen-gogo.

It works in concert with the Go source code generated +for .proto files by the protocol compiler. + +A summary of the properties of the protocol buffer interface +for a protocol buffer variable v: + + - Names are turned from camel_case to CamelCase for export. + - There are no methods on v to set fields; just treat + them as structure fields. + - There are getters that return a field's value if set, + and return the field's default value if unset. + The getters work even if the receiver is a nil message. + - The zero value for a struct is its correct initialization state. + All desired fields must be set before marshaling. + - A Reset() method will restore a protobuf struct to its zero state. + - Non-repeated fields are pointers to the values; nil means unset. + That is, optional or required field int32 f becomes F *int32. + - Repeated fields are slices. + - Helper functions are available to aid the setting of fields. + msg.Foo = proto.String("hello") // set field + - Constants are defined to hold the default values of all fields that + have them. They have the form Default_StructName_FieldName. + Because the getter methods handle defaulted values, + direct use of these constants should be rare. + - Enums are given type names and maps from names to values. + Enum values are prefixed by the enclosing message's name, or by the + enum's type name if it is a top-level enum. Enum types have a String + method, and a Enum method to assist in message construction. + - Nested messages, groups and enums have type names prefixed with the name of + the surrounding message type. + - Extensions are given descriptor names that start with E_, + followed by an underscore-delimited list of the nested messages + that contain it (if any) followed by the CamelCased name of the + extension field itself. HasExtension, ClearExtension, GetExtension + and SetExtension are functions for manipulating extensions. + - Oneof field sets are given a single field in their message, + with distinguished wrapper types for each possible field value. + - Marshal and Unmarshal are functions to encode and decode the wire format. + +When the .proto file specifies `syntax="proto3"`, there are some differences: + + - Non-repeated fields of non-message type are values instead of pointers. + - Enum types do not get an Enum method. + +The simplest way to describe this is to see an example. +Given file test.proto, containing + + package example;

If the +second list is empty, the result will always return true. + + sets.contains(list(T), list(T)) -> bool + +Examples: + + sets.contains([], []) // true + sets.contains([], [1]) // false + sets.contains([1, 2, 3, 4], [2, 3]) // true + sets.contains([1, 2.0, 3u], [1.0, 2u, 3]) // true + +### Sets.Equivalent + +Returns whether the first and second list are set equivalent. Lists are set +equivalent if for every item in the first list, there is an element in the +second which is equal. The lists may not be of the same size as they do not +guarantee the elements within them are unique, so size does not factor into +the computation. + + sets.equivalent(list(T), list(T)) -> bool + +Examples: + + sets.equivalent([], []) // true + sets.equivalent([1], [1, 1]) // true + sets.equivalent([1], [1u, 1.0]) // true + sets.equivalent([1, 2, 3], [3u, 2.0, 1]) // true + +### Sets.Intersects + +Returns whether the first list has at least one element whose value is equal +to an element in the second list. If either list is empty, the result will +be false. + + sets.intersects(list(T), list(T)) -> bool + +Examples: + + sets.intersects([1], []) // false + sets.intersects([1], [1, 2]) // true + sets.intersects([[1], [2, 3]], [[1, 2], [2, 3.0]]) // true + +## Strings + +Extended functions for string manipulation. As a general note, all indices are +zero-based. + +### CharAt + +Returns the character at the given position.

If the +search string is not found the function returns -1. + +The function also accepts an optional position from which to begin the +substring search. If the substring is the empty string, the index where the +search starts is returned (zero or custom). + + .indexOf() -> + .indexOf(, ) -> + +Examples: + + 'hello mellow'.indexOf('') // returns 0 + 'hello mellow'.indexOf('ello') // returns 1 + 'hello mellow'.indexOf('jello') // returns -1 + 'hello mellow'.indexOf('', 2) // returns 2 + 'hello mellow'.indexOf('ello', 2) // returns 7 + 'hello mellow'.indexOf('ello', 20) // returns -1 + 'hello mellow'.indexOf('ello', -1) // error + +### Join + +Returns a new string where the elements of string list are concatenated. + +The function also accepts an optional separator which is placed between +elements in the resulting string. + + >.join() -> + >.join() -> + +Examples: + + ['hello', 'mellow'].join() // returns 'hellomellow' + ['hello', 'mellow'].join(' ') // returns 'hello mellow' + [].join() // returns '' + [].join('/') // returns '' + +### LastIndexOf + +Returns the integer index of the last occurrence of the search string. If the +search string is not found the function returns -1. + +The function also accepts an optional position which represents the last index +to be considered as the beginning of the substring match. If the substring is +the empty string, the index where the search starts is returned (string length +or custom). + + .lastIndexOf() -> + .lastIndexOf(, ) -> + +Examples: + + 'hello mellow'.lastIndexOf('') // returns 12 + 'hello mellow'.lastIndexOf('ello') // returns 7 + 'hello mellow'.lastIndexOf('jello') // returns -1 + 'hello mellow'.lastIndexOf('ello', 6) // returns 1 + 'hello mellow'.lastIndexOf('ello', 20) // returns -1 + 'hello mellow'.lastIndexOf('ello', -1) // error + +### LowerAscii + +Returns a new string where all ASCII characters are lower-cased. + +This function does not perform Unicode case-mapping for characters outside the +ASCII range. + + .lowerAscii() -> + +Examples: + + 'TacoCat'.lowerAscii() // returns 'tacocat' + 'TacoCÆt Xii'.lowerAscii() // returns 'tacocÆt xii' + +### Quote + +**Introduced in version 1** + +Takes the given string and makes it safe to print (without any formatting due to escape sequences). +If any invalid UTF-8 characters are encountered, they are replaced with \uFFFD. + + strings.quote() + +Examples: + + strings.quote('single-quote with "double quote"') // returns '"single-quote with \"double quote\""' + strings.quote("two escape sequences \a\n") // returns '"two escape sequences \\a\\n"' + +### Replace + +Returns a new string based on the target, which replaces the occurrences of a +search string with a replacement string if present. The function accepts an +optional limit on the number of substring replacements to be made. + +When the replacement limit is 0, the result is the original string. When the +limit is a negative number, the function behaves the same as replace all. + + .replace(, ) -> + .replace(, , ) -> + +Examples: + + 'hello hello'.replace('he', 'we') // returns 'wello wello' + 'hello hello'.replace('he', 'we', -1) // returns 'wello wello' + 'hello hello'.replace('he', 'we', 1) // returns 'wello hello' + 'hello hello'.replace('he', 'we', 0) // returns 'hello hello' + +### Split + +Returns a list of strings split from the input by the given separator. The +function accepts an optional argument specifying a limit on the number of +substrings produced by the split. + +When the split limit is 0, the result is an empty list. When the limit is 1, +the result is the target string to split. When the limit is a negative +number, the function behaves the same as split all. + + .split() -> > + .split(, ) -> > + +Examples: + + 'hello hello hello'.split(' ') // returns ['hello', 'hello', 'hello'] + 'hello hello hello'.split(' ', 0) // returns [] + 'hello hello hello'.split(' ', 1) // returns ['hello hello hello'] + 'hello hello hello'.split(' ', 2) // returns ['hello', 'hello hello'] + 'hello hello hello'.split(' ', -1) // returns ['hello', 'hello', 'hello'] + +### Substring + +Returns the substring given a numeric range corresponding to character +positions. Optionally may omit the trailing range for a substring from a given +character position until the end of a string. + +Character offsets are 0-based with an inclusive start range and exclusive end +range. It is an error to specify an end range that is lower than the start +range, or for either the start or end index to be negative or exceed the string +length. + + .substring() -> + .substring(, ) -> + +Examples: + + 'tacocat'.substring(4) // returns 'cat' + 'tacocat'.substring(0, 4) // returns 'taco' + 'tacocat'.substring(-1) // error + 'tacocat'.substring(2, 1) // error + +### Trim + +Returns a new string which removes the leading and trailing whitespace in the +target string. The trim function uses the Unicode definition of whitespace +which does not include the zero-width spaces. See: +https://en.wikipedia.org/wiki/Whitespace_character#Unicode + + .trim() -> + +Examples: + + ' \ttrim\n '.trim() // returns 'trim' + +### UpperAscii + +Returns a new string where all ASCII characters are upper-cased. + +This function does not perform Unicode case-mapping for characters outside the +ASCII range. + + .upperAscii() -> + +Examples: + + 'TacoCat'.upperAscii() // returns 'TACOCAT' + 'TacoCÆt Xii'.upperAscii() // returns 'TACOCÆT XII' + +### Reverse + +Returns a new string whose characters are the same as the target string, only formatted in +reverse order. +This function relies on converting strings to rune arrays in order to reverse. +It can be located in Version 3 of strings. + + .reverse() -> + +Examples: + + 'gums'.reverse() // returns 'smug' + 'John Smith'.reverse() // returns 'htimS nhoJ' + +## TwoVarComprehensions + +TwoVarComprehensions introduces support for two-variable comprehensions. + +The two-variable form of comprehensions looks similar to the one-variable +counterparts. Where possible, the same macro names were used and additional +macro signatures added. The notable distinction for two-variable comprehensions +is the introduction of `transformList`, `transformMap`, and `transformMapEntry` +support for list and map types rather than the more traditional `map` and +`filter` macros. + +### All + +Comprehension which tests whether all elements in the list or map satisfy a +given predicate. The `all` macro evaluates in a manner consistent with logical +AND and will short-circuit when encountering a `false` value. + + .all(indexVar, valueVar, ) -> bool + .all(keyVar, valueVar, ) -> bool + +Examples: + + [1, 2, 3].all(i, j, i < j) // returns true + {'hello': 'world', 'taco': 'taco'}.all(k, v, k != v) // returns false + + // Combines two-variable comprehension with single variable + {'h': ['hello', 'hi'], 'j': ['joke', 'jog']} + .all(k, vals, vals.all(v, v.startsWith(k))) // returns true + +### Exists + +Comprehension which tests whether any element in a list or map exists which +satisfies a given predicate. The `exists` macro evaluates in a manner consistent +with logical OR and will short-circuit when encountering a `true` value. + + .exists(indexVar, valueVar, ) -> bool + .exists(keyVar, valueVar, ) -> bool + +Examples: + + {'greeting': 'hello', 'farewell': 'goodbye'} + .exists(k, v, k.startsWith('good') || v.endsWith('bye')) // returns true + [1, 2, 4, 8, 16].exists(i, v, v == 1024 && i == 10) // returns false + +### ExistsOne + +Comprehension which tests whether exactly one element in a list or map exists +which satisfies a given predicate expression. This comprehension does not +short-circuit in keeping with the one-variable exists one macro semantics. + + .existsOne(indexVar, valueVar, ) + .existsOne(keyVar, valueVar, ) + +This macro may also be used with the `exists_one` function name, for +compatibility with the one-variable macro of the same name. + +Examples: + + [1, 2, 1, 3, 1, 4].existsOne(i, v, i == 1 || v == 1) // returns false + [1, 1, 2, 2, 3, 3].existsOne(i, v, i == 2 && v == 2) // returns true + {'i': 0, 'j': 1, 'k': 2}.existsOne(i, v, i == 'l' || v == 1) // returns true + +### TransformList + +Comprehension which converts a map or a list into a list value.

The output +expression of the comprehension determines the value of the output map entry; +however, the key remains fixed. Elements in the map may optionally be filtered +according to a predicate expression, where elements that satisfy the predicate +are transformed. + + .transformMap(indexVar, valueVar, ) + .transformMap(indexVar, valueVar, , ) + .transformMap(keyVar, valueVar, ) + .transformMap(keyVar, valueVar, , ) + +Examples: + + [1, 2, 3].transformMap(indexVar, valueVar, + (indexVar * valueVar) + valueVar) // returns {0: 1, 1: 4, 2: 9} + [1, 2, 3].transformMap(indexVar, valueVar, indexVar % 2 == 0 + (indexVar * valueVar) + valueVar) // returns {0: 1, 2: 9} + {'greeting': 'hello'}.transformMap(k, v, v + '!') // returns {'greeting': 'hello!'} + +### TransformMapEntry + +Comprehension which converts a map or a list into a map value; however, this +transform expects the entry expression be a map literal.

It is a perfect way to implement +common patterns: auth, logging and... monitoring. + +To use Interceptors in chains, please see [`go-grpc-middleware`](https://github.com/mwitkow/go-grpc-middleware). + +## Usage + +There are two types of interceptors: client-side and server-side. This package provides monitoring Interceptors for both. + +### Server-side + +```go +import "github.com/grpc-ecosystem/go-grpc-prometheus" +... + // Initialize your gRPC server's interceptor. + myServer := grpc.NewServer( + grpc.StreamInterceptor(grpc_prometheus.StreamServerInterceptor), + grpc.UnaryInterceptor(grpc_prometheus.UnaryServerInterceptor), + ) + // Register your gRPC service implementations. + myservice.RegisterMyServiceServer(s.server, &myServiceImpl{}) + // After all your registrations, make sure all of the Prometheus metrics are initialized. + grpc_prometheus.Register(myServer) + // Register Prometheus metrics handler. + http.Handle("/metrics", promhttp.Handler()) +... +``` + +### Client-side + +```go +import "github.com/grpc-ecosystem/go-grpc-prometheus" +... + clientConn, err = grpc.Dial( + address, + grpc.WithUnaryInterceptor(grpc_prometheus.UnaryClientInterceptor), + grpc.WithStreamInterceptor(grpc_prometheus.StreamClientInterceptor) + ) + client = pb_testproto.NewTestServiceClient(clientConn) + resp, err := client.PingEmpty(s.ctx, &myservice.Request{Msg: "hello"}) +... +``` + +# Metrics + +## Labels + +All server-side metrics start with `grpc_server` as Prometheus subsystem name. All client-side metrics start with `grpc_client`. Both of them have mirror-concepts. Similarly all methods +contain the same rich labels: + + * `grpc_service` - the [gRPC service](http://www.grpc.io/docs/#defining-a-service) name, which is the combination of protobuf `package` and + the `grpc_service` section name. E.g. for `package = mwitkow.testproto` and + `service TestService` the label will be `grpc_service="mwitkow.testproto.TestService"` + * `grpc_method` - the name of the method called on the gRPC service. E.g. + `grpc_method="Ping"` + * `grpc_type` - the gRPC [type of request](http://www.grpc.io/docs/guides/concepts.html#rpc-life-cycle). + Differentiating between the two is important especially for latency measurements. + + - `unary` is single request, single response RPC + - `client_stream` is a multi-request, single response RPC + - `server_stream` is a single request, multi-response RPC + - `bidi_stream` is a multi-request, multi-response RPC + + +Additionally for completed RPCs, the following labels are used: + + * `grpc_code` - the human-readable [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go). + The list of all statuses is to long, but here are some common ones: + + - `OK` - means the RPC was successful + - `IllegalArgument` - RPC contained bad values + - `Internal` - server-side error not disclosed to the clients + +## Counters + +The counters and their up to date documentation is in [server_reporter.go](server_reporter.go) and [client_reporter.go](client_reporter.go) +the respective Prometheus handler (usually `/metrics`). + +For the purpose of this documentation we will only discuss `grpc_server` metrics. The `grpc_client` ones contain mirror concepts. + +For simplicity, let's assume we're tracking a single server-side RPC call of [`mwitkow.testproto.TestService`](examples/testproto/test.proto), +calling the method `PingList`. The call succeeds and returns 20 messages in the stream. + +First, immediately after the server receives the call it will increment the +`grpc_server_started_total` and start the handling time clock (if histograms are enabled). + +```jsoniq +grpc_server_started_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +Then the user logic gets invoked. It receives one message from the client containing the request +(it's a `server_stream`): + +```jsoniq +grpc_server_msg_received_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +The user logic may return an error, or send multiple messages back to the client.

However, since it is bad practice to have metrics +of [high cardinality](https://prometheus.io/docs/practices/instrumentation/#do-not-overuse-labels) +the latency monitoring metrics are disabled by default. To enable them please call the following +in your server initialization code: + +```jsoniq +grpc_prometheus.EnableHandlingTimeHistogram() +``` + +After the call completes, its handling time will be recorded in a [Prometheus histogram](https://prometheus.io/docs/concepts/metric_types/#histogram) +variable `grpc_server_handling_seconds`.

The verbosity of above metrics make it possible to have that +flexibility. Here's a couple of useful monitoring queries: + + +### request inbound rate +```jsoniq +sum(rate(grpc_server_started_total{job="foo"}[1m])) by (grpc_service) +``` +For `job="foo"` (common label to differentiate between Prometheus monitoring targets), calculate the +rate of requests per second (1 minute window) for each gRPC `grpc_service` that the job has. Please note +how the `grpc_method` is being omitted here: all methods of a given gRPC service will be summed together. + +### unary request error rate +```jsoniq +sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service) +``` +For `job="foo"`, calculate the per-`grpc_service` rate of `unary` (1:1) RPCs that failed, i.e. the +ones that didn't finish with `OK` code. + +### unary request error percentage +```jsoniq +sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service) + / +sum(rate(grpc_server_started_total{job="foo",grpc_type="unary"}[1m])) by (grpc_service) + * 100.0 +``` +For `job="foo"`, calculate the percentage of failed requests by service. It's easy to notice that +this is a combination of the two above examples. This is an example of a query you would like to +[alert on](https://prometheus.io/docs/alerting/rules/) in your system for SLA violations, e.g. +"no more than 1% requests should fail". + +### average response stream size +```jsoniq +sum(rate(grpc_server_msg_sent_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service) + / +sum(rate(grpc_server_started_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service) +``` +For `job="foo"` what is the `grpc_service`-wide `10m` average of messages returned for all ` +server_stream` RPCs. This allows you to track the stream sizes returned by your system, e.g. allows +you to track when clients started to send "wide" queries that ret +Note the divisor is the number of started RPCs, in order to account for in-flight requests. + +### 99%-tile latency of unary requests +```jsoniq +histogram_quantile(0.99, + sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary"}[5m])) by (grpc_service,le) +) +``` +For `job="foo"`, returns an 99%-tile [quantile estimation](https://prometheus.io/docs/practices/histograms/#quantiles) +of the handling time of RPCs per service. Please note the `5m` rate, this means that the quantile +estimation will take samples in a rolling `5m` window. When combined with other quantiles +(e.g. 50%, 90%), this query gives you tremendous insight into the responsiveness of your system +(e.g. impact of caching). + +### percentage of slow unary queries (>250ms) +```jsoniq +100.0 - ( +sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary",le="0.25"}[5m])) by (grpc_service) + / +sum(rate(grpc_server_handling_seconds_count{job="foo",grpc_type="unary"}[5m])) by (grpc_service) +) * 100.0 +``` +For `job="foo"` calculate the by-`grpc_service` fraction of slow requests that took longer than `0.25` +seconds. This query is relatively complex, since the Prometheus aggregations use `le` (less or equal) +buckets, meaning that counting "fast" requests fractions is easier. However, simple maths helps. +This is an example of a query you would like to alert on in your system for SLA violations, +e.g. "less than 1% of requests are slower than 250ms". + + +## Status + +This code has been used since August 2015 as the basis for monitoring of *production* gRPC micro services at [Improbable](https://improbable.io). + +## License + +`go-grpc-prometheus` is released under the Apache 2.0 license.

(#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. (#2166) +- The `"go.opentelemetry.io/otel/attribute".Array` function and the related `ARRAY` value type is deprecated. + Use the typed `*Slice` functions and types added to the package 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.InstrumentConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#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".SpanContextFromContext` 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.

(#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`.

(#1633) +- Removed the exported `SimpleSpanProcessor` and `BatchSpanProcessor` structs. + These are now returned as a SpanProcessor interface from their respective constructors. (#1638) +- Removed `WithRecord()` from `trace.SpanOption` when creating a span. (#1660) +- Removed setting status to `Error` while recording an error as a span event in `RecordError`. (#1663) +- Removed `jaeger.WithProcess` configuration option. (#1673) +- Removed `ApplyConfig` method from `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` and the now unneeded `Config` struct. (#1693) + +### Fixed + +- Jaeger Exporter: Ensure mapping between OTEL and Jaeger span data complies with the specification. (#1626) +- `SamplingResult.TraceState` is correctly propagated to a newly created span's `SpanContext`.

(#1062) +- A new `WithSpanProcessor` `ProviderOption` is added to the `go.opentelemetry.io/otel/sdk/trace` package to create a `Provider` and automatically register the `SpanProcessor`. (#1078) + +### Changed + +- Rename `sdk/metric/processor/test` to `sdk/metric/processor/processortest`. (#1049) +- Rename `sdk/metric/controller/test` to `sdk/metric/controller/controllertest`.

(#1024) +- The `go.opentelemetry.io/otel/bridge/opentracing` bridge package has been made into its own module. + This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038) +- Renamed `go.opentelemetry.io/otel/api/standard` package to `go.opentelemetry.io/otel/semconv` to avoid the ambiguous and generic name `standard` and better describe the package as containing OpenTelemetry semantic conventions. (#1016) +- The environment variable used for resource detection has been changed from `OTEL_RESOURCE_LABELS` to `OTEL_RESOURCE_ATTRIBUTES` (#1042) +- Replace `WithSyncer` with `WithBatcher` in examples.

(#1046) +- Merge the `go.opentelemetry.io/otel/api/label` and `go.opentelemetry.io/otel/api/kv` into the new `go.opentelemetry.io/otel/label` package. (#1060) +- Unify Callback Function Naming. + Rename `*Callback` with `*Func`. (#1061) +- CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064) +- The `go.opentelemetry.io/otel/sdk/export/trace` interfaces `SpanSyncer` and `SpanBatcher` have been replaced with a specification compliant `Exporter` interface. + This interface still supports the export of `SpanData`, but only as a slice. + Implementation are also required now to return any error from `ExportSpans` if one occurs as well as implement a `Shutdown` method for exporter clean-up. (#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-collector 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. (#806) +- Update error handling for any one off error handlers, replacing, instead, with the `global.Handle` function. (#791) +- Rename `plugin` directory to `instrumentation` to match the OpenTelemetry specification. (#779) +- Makes the argument order to Histogram and DDSketch `New()` consistent. (#781) + +### Removed + +- `Uint64NumberKind` and related functions from the API. (#864) +- Context arguments from `Aggregator.Checkpoint` and `Integrator.Process` as they were unused. (#803) +- `SpanID` is no longer included in parameters for sampling decision to match the OpenTelemetry specification. (#775) + +### Fixed + +- Upgrade OTLP exporter to opentelemetry-proto matching the opentelemetry-collector v0.4.0 release.

(#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.

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). + +## Tests + +Each functionality should be covered by tests. + +Performance-critical functionality should also be covered by benchmarks. + +- Pull requests adding a performance-critical functionality +should have `go test -bench` output in their description. +- Pull requests changing a performance-critical functionality +should have [`benchstat`](https://pkg.go.dev/golang.org/x/perf/cmd/benchstat) +output in their description. + +## 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. + +### README files + +Each (non-internal, non-test, non-documentation) package must contain a +`README.md` file containing at least a title, and a `pkg.go.dev` badge. + +The README should not be a repetition of Go doc comments. + +You can verify the presence of all README files with the `make verify-readmes` +command. + +## 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. + +See also: +[Keeping Your Modules Compatible: Working with interfaces](https://go.dev/blog/module-compatibility#working-with-interfaces). + +### 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. The top-level tests with this term will be run +many times in the `test-concurrent-safe` CI job to increase the chance of +catching concurrency issues. This does not apply to subtests when this term +is not in their root name. + +### 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. See [#4404] for an example of +this. + +[^3]: https://github.com/open-telemetry/opentelemetry-go/issues/3548 + +### Ignoring context cancellation + +OpenTelemetry API implementations need to ignore the cancellation of the context that are +passed when recording a value (e.g. starting a span, recording a measurement, emitting a log). +Recording methods should not return an error describing the cancellation state of the context +when they complete, nor should they abort any work. + +This rule may not apply if the OpenTelemetry specification defines a timeout mechanism for +the method. In that case the context cancellation can be used for the timeout with the +restriction that this behavior is documented for the method. Otherwise, timeouts +are expected to be handled by the user calling the API, not the implementation. + +Stoppage of the telemetry pipeline is handled by calling the appropriate `Shutdown` method +of a provider. It is assumed the context passed from a user is not used for this purpose. + +Outside of the direct recording of telemetry from the API (e.g. exporting telemetry, +force flushing telemetry, shutting down a signal provider) the context cancellation +should be honored. This means all work done on behalf of the user provided context +should be canceled. + +## Approvers and Maintainers + +### Triagers + +- [Alex Kats](https://github.com/akats7), Capital One +- [Cheng-Zhen Yang](https://github.com/scorpionknifes), Independent + +### Approvers + +### Maintainers + +- [Damien Mathieu](https://github.com/dmathieu), Elastic +- [David Ashpole](https://github.com/dashpole), Google +- [Robert Pająk](https://github.com/pellared), Splunk +- [Sam Xie](https://github.com/XSAM), Cisco/AppDynamics +- [Tyler Yahn](https://github.com/MrAlias), Splunk + +### Emeritus + +- [Aaron Clawson](https://github.com/MadVikingGod) +- [Anthony Mirabella](https://github.com/Aneurysm9) +- [Chester Cheung](https://github.com/hanyuancheung) +- [Evan Torrie](https://github.com/evantorrie) +- [Gustavo Silva Paiva](https://github.com/paivagustavo) +- [Josh MacDonald](https://github.com/jmacd) +- [Liz Fong-Jones](https://github.com/lizthegrey) + +### Become an Approver or a Maintainer + +See the [community membership document in OpenTelemetry community +repo](https://github.com/open-telemetry/community/blob/main/guides/contributor/membership.md). + +[Approver]: #approvers +[Maintainer]: #maintainers +[gotmpl]: https://pkg.go.dev/go.opentelemetry.io/build-tools/gotmpl +[#4404]: https://github.com/open-telemetry/opentelemetry-go/pull/4404 diff --git a/vendor/go.opentelemetry.io/otel/LICENSE b/vendor/go.opentelemetry.io/otel/LICENSE new file mode 100644 index 00000000..261eeb9e --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/LICENSE @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

information and stability guarantees can be found in the +[versioning documentation](VERSIONING.md). + +[^1]: https://github.com/orgs/open-telemetry/projects/43 + +### Compatibility + +OpenTelemetry-Go ensures compatibility with the current supported versions of +the [Go language](https://golang.org/doc/devel/release#policy): + +> Each major Go release is supported until there are two newer major releases. +> For example, Go 1.5 was supported until the Go 1.7 release, and Go 1.6 was supported until the Go 1.8 release. + +For versions of Go that are no longer supported upstream, opentelemetry-go will +stop ensuring compatibility with these versions in the following manner: + +- A minor release of opentelemetry-go will be made to add support for the new + supported release of Go. +- The following minor release of opentelemetry-go will remove compatibility + testing for the oldest (now archived upstream) version of Go. This, and + future, releases of opentelemetry-go may include features only supported by + the currently supported versions of Go. + +Currently, this project supports the following environments. + +| OS | Go Version | Architecture | +|----------|------------|--------------| +| Ubuntu | 1.24 | amd64 | +| Ubuntu | 1.23 | amd64 | +| Ubuntu | 1.24 | 386 | +| Ubuntu | 1.23 | 386 | +| Ubuntu | 1.24 | arm64 | +| Ubuntu | 1.23 | arm64 | +| macOS 13 | 1.24 | amd64 | +| macOS 13 | 1.23 | amd64 | +| macOS | 1.24 | arm64 | +| macOS | 1.23 | arm64 | +| Windows | 1.24 | amd64 | +| Windows | 1.23 | amd64 | +| Windows | 1.24 | 386 | +| Windows | 1.23 | 386 | + +While this project should work for other systems, no compatibility guarantees +are made for those systems currently. + +## Getting Started + +You can find a getting started guide on [opentelemetry.io](https://opentelemetry.io/docs/languages/go/getting-started/). + +OpenTelemetry's goal is to provide a single set of APIs to capture distributed +traces and metrics from your application and send them to an observability +platform. 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 [examples](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/examples) +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 | Logs | 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 00000000..7c1a9119 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/RELEASING.md @@ -0,0 +1,150 @@ +# Release Process + +## Create a `Version Release` issue + +Create a `Version Release` issue to track the 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.

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/README.md b/vendor/go.opentelemetry.io/otel/attribute/README.md new file mode 100644 index 00000000..5b3da8f1 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/README.md @@ -0,0 +1,3 @@ +# Attribute + +[![PkgGoDev](https://pkg.go.dev/badge/go.opentelemetry.io/otel/attribute)](https://pkg.go.dev/go.opentelemetry.io/otel/attribute) 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 00000000..eef51ebc --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/doc.go @@ -0,0 +1,5 @@ +// Copyright The OpenTelemetry Authors +// SPDX-License-Identifier: Apache-2.0 + +// 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 00000000..318e42fc --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/encoder.go @@ -0,0 +1,135 @@ +// Copyright The OpenTelemetry Authors +// SPDX-License-Identifier: Apache-2.0 + +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. + +# Instrument Name + +OpenTelemetry defines an [instrument name syntax] that restricts what +instrument names are allowed. + +Instrument names should ... + + - Not be empty. + - Have an alphabetic character as their first letter. + - Have any letter after the first be an alphanumeric character, ‘_’, ‘.’, + ‘-’, or ‘/’. + - Have a maximum length of 255 letters. + +To ensure compatibility with observability platforms, all instruments created +need to conform to this syntax. Not all implementations of the API will validate +these names, it is the callers responsibility to ensure compliance. + +# 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. + +[instrument name syntax]: https://opentelemetry.io/docs/specs/otel/metrics/api/#instrument-name-syntax +[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/README.md b/vendor/go.opentelemetry.io/otel/metric/embedded/README.md new file mode 100644 index 00000000..1f6e0efa --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/metric/embedded/README.md @@ -0,0 +1,3 @@ +# Metric Embedded + +[![PkgGoDev](https://pkg.go.dev/badge/go.opentelemetry.io/otel/metric/embedded)](https://pkg.go.dev/go.opentelemetry.io/otel/metric/embedded) 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 00000000..1a9dc680 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/metric/embedded/embedded.go @@ -0,0 +1,243 @@ +// Copyright The OpenTelemetry Authors +// SPDX-License-Identifier: Apache-2.0 + +// 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.

For message translation to function properly, a translation should +// be defined for each key for each supported language. A dictionary may be +// underspecified, though, if there is a parent language that already defines +// the key. For example, a Dictionary for "en-GB" could leave out entries that +// are identical to those in a dictionary for "en". +// +// # Messages +// +// A Message is a format string which varies on the value of substitution +// variables. For instance, to indicate the number of results one could want "no +// results" if there are none, "1 result" if there is 1, and "%d results" for +// any other number. Catalog is agnostic to the kind of format strings that are +// used: for instance, messages can follow either the printf-style substitution +// from package fmt or use templates. +// +// A Message does not substitute arguments in the format string. This job is +// reserved for packages that render strings, such as message, that use Catalogs +// to selected string. This separation of concerns allows Catalog to be used to +// store any kind of formatting strings. +// +// # Selecting messages based on linguistic features of substitution arguments +// +// Messages may vary based on any linguistic features of the argument values. +// The most common one is plural form, but others exist. +// +// Selection messages are provided in packages that provide support for a +// specific linguistic feature. The following snippet uses plural.Selectf: +// +// catalog.Set(language.English, "You are %d minute(s) late.", +// plural.Selectf(1, "", +// plural.One, "You are 1 minute late.", +// plural.Other, "You are %d minutes late.")) +// +// In this example, a message is stored in the Catalog where one of two messages +// is selected based on the first argument, a number. The first message is +// selected if the argument is singular (identified by the selector "one") and +// the second message is selected in all other cases. The selectors are defined +// by the plural rules defined in CLDR. The selector "other" is special and will +// always match. Each language always defines one of the linguistic categories +// to be "other." For English, singular is "one" and plural is "other". +// +// Selects can be nested. This allows selecting sentences based on features of +// multiple arguments or multiple linguistic properties of a single argument. +// +// # String interpolation +// +// There is often a lot of commonality between the possible variants of a +// message. For instance, in the example above the word "minute" varies based on +// the plural catogory of the argument, but the rest of the sentence is +// identical. Using interpolation the above message can be rewritten as: +// +// catalog.Set(language.English, "You are %d minute(s) late.", +// catalog.Var("minutes", +// plural.Selectf(1, "", plural.One, "minute", plural.Other, "minutes")), +// catalog.String("You are %[1]d ${minutes} late.")) +// +// Var is defined to return the variable name if the message does not yield a +// match. This allows us to further simplify this snippet to +// +// catalog.Set(language.English, "You are %d minute(s) late.", +// catalog.Var("minutes", plural.Selectf(1, "", plural.One, "minute")), +// catalog.String("You are %d ${minutes} late.")) +// +// Overall this is still only a minor improvement, but things can get a lot more +// unwieldy if more than one linguistic feature is used to determine a message +// variant. Consider the following example: +// +// // argument 1: list of hosts, argument 2: list of guests +// catalog.Set(language.English, "%[1]v invite(s) %[2]v to their party.", +// catalog.Var("their", +// plural.Selectf(1, "" +// plural.One, gender.Select(1, "female", "her", "other", "his"))), +// catalog.Var("invites", plural.Selectf(1, "", plural.One, "invite")) +// catalog.String("%[1]v ${invites} %[2]v to ${their} party.")), +// +// Without variable substitution, this would have to be written as +// +// // argument 1: list of hosts, argument 2: list of guests +// catalog.Set(language.English, "%[1]v invite(s) %[2]v to their party.", +// plural.Selectf(1, "", +// plural.One, gender.Select(1, +// "female", "%[1]v invites %[2]v to her party." +// "other", "%[1]v invites %[2]v to his party."), +// plural.Other, "%[1]v invites %[2]v to their party.")) +// +// Not necessarily shorter, but using variables there is less duplication and +// the messages are more maintenance friendly. Moreover, languages may have up +// to six plural forms.

The mapping specifies +// how different portions of the gRPC request message are mapped to the URL +// path, URL query parameters, and HTTP request body. It also controls how the +// gRPC response message is mapped to the HTTP response body. `HttpRule` is +// typically specified as an `google.api.http` annotation on the gRPC method. +// +// Each mapping specifies a URL path template and an HTTP method. The path +// template may refer to one or more fields in the gRPC request message, as long +// as each field is a non-repeated field with a primitive (non-message) type. +// The path template controls how fields of the request message are mapped to +// the URL path. +// +// Example: +// +// service Messaging { +// rpc GetMessage(GetMessageRequest) returns (Message) { +// option (google.api.http) = { +// get: "/v1/{name=messages/*}" +// }; +// } +// } +// message GetMessageRequest { +// string name = 1; // Mapped to URL path. +// } +// message Message { +// string text = 1; // The resource content. +// } +// +// This enables an HTTP REST to gRPC mapping as below: +// +// - HTTP: `GET /v1/messages/123456` +// - gRPC: `GetMessage(name: "messages/123456")` +// +// Any fields in the request message which are not bound by the path template +// automatically become HTTP query parameters if there is no HTTP request body. +// For example: +// +// service Messaging { +// rpc GetMessage(GetMessageRequest) returns (Message) { +// option (google.api.http) = { +// get:"/v1/messages/{message_id}" +// }; +// } +// } +// message GetMessageRequest { +// message SubMessage { +// string subfield = 1; +// } +// string message_id = 1; // Mapped to URL path. +// int64 revision = 2; // Mapped to URL query parameter `revision`. +// SubMessage sub = 3; // Mapped to URL query parameter `sub.subfield`. +// } +// +// This enables a HTTP JSON to RPC mapping as below: +// +// - HTTP: `GET /v1/messages/123456?revision=2&sub.subfield=foo` +// - gRPC: `GetMessage(message_id: "123456" revision: 2 sub: +// SubMessage(subfield: "foo"))` +// +// Note that fields which are mapped to URL query parameters must have a +// primitive type or a repeated primitive type or a non-repeated message type. +// In the case of a repeated type, the parameter can be repeated in the URL +// as `...?param=A¶m=B`. In the case of a message type, each field of the +// message is mapped to a separate parameter, such as +// `...?foo.a=A&foo.b=B&foo.c=C`. +// +// For HTTP methods that allow a request body, the `body` field +// specifies the mapping. Consider a REST update method on the +// message resource collection: +// +// service Messaging { +// rpc UpdateMessage(UpdateMessageRequest) returns (Message) { +// option (google.api.http) = { +// patch: "/v1/messages/{message_id}" +// body: "message" +// }; +// } +// } +// message UpdateMessageRequest { +// string message_id = 1; // mapped to the URL +// Message message = 2; // mapped to the body +// } +// +// The following HTTP JSON to RPC mapping is enabled, where the +// representation of the JSON in the request body is determined by +// protos JSON encoding: +// +// - HTTP: `PATCH /v1/messages/123456 { "text": "Hi!" }` +// - gRPC: `UpdateMessage(message_id: "123456" message { text: "Hi!" })` +// +// The special name `*` can be used in the body mapping to define that +// every field not bound by the path template should be mapped to the +// request body. This enables the following alternative definition of +// the update method: +// +// service Messaging { +// rpc UpdateMessage(Message) returns (Message) { +// option (google.api.http) = { +// patch: "/v1/messages/{message_id}" +// body: "*" +// }; +// } +// } +// message Message { +// string message_id = 1; +// string text = 2; +// } +// +// The following HTTP JSON to RPC mapping is enabled: +// +// - HTTP: `PATCH /v1/messages/123456 { "text": "Hi!" }` +// - gRPC: `UpdateMessage(message_id: "123456" text: "Hi!")` +// +// Note that when using `*` in the body mapping, it is not possible to +// have HTTP parameters, as all fields not bound by the path end in +// the body. This makes this option more rarely used in practice when +// defining REST APIs. The common usage of `*` is in custom methods +// which don't use the URL at all for transferring data. +// +// It is possible to define multiple HTTP methods for one RPC by using +// the `additional_bindings` option. Example: +// +// service Messaging { +// rpc GetMessage(GetMessageRequest) returns (Message) { +// option (google.api.http) = { +// get: "/v1/messages/{message_id}" +// additional_bindings { +// get: "/v1/users/{user_id}/messages/{message_id}" +// } +// }; +// } +// } +// message GetMessageRequest { +// string message_id = 1; +// string user_id = 2; +// } +// +// This enables the following two alternative HTTP JSON to RPC mappings: +// +// - HTTP: `GET /v1/messages/123456` +// - gRPC: `GetMessage(message_id: "123456")` +// +// - HTTP: `GET /v1/users/me/messages/123456` +// - gRPC: `GetMessage(user_id: "me" message_id: "123456")` +// +// # Rules for HTTP mapping +// +// 1.

The +// service config is simply the YAML representation of the `google.api.Service` +// proto message. +// +// As an alternative to annotating your proto file, you can configure gRPC +// transcoding in your service config YAML files. You do this by specifying a +// `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same +// effect as the proto annotation. This can be particularly useful if you +// have a proto that is reused in multiple services. Note that any transcoding +// specified in the service config will override any matching transcoding +// configuration in the proto. +// +// The following example selects a gRPC method and applies an `HttpRule` to it: +// +// http: +// rules: +// - selector: example.v1.Messaging.GetMessage +// get: /v1/messages/{message_id}/{sub.subfield} +// +// # Special notes +// +// When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the +// proto to JSON conversion must follow the [proto3 +// specification](https://developers.google.com/protocol-buffers/docs/proto3#json). +// +// While the single segment variable follows the semantics of +// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String +// Expansion, the multi segment variable **does not** follow RFC 6570 Section +// 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion +// does not expand special characters like `?` and `#`, which would lead +// to invalid URLs. As the result, gRPC Transcoding uses a custom encoding +// for multi segment variables. +// +// The path variables **must not** refer to any repeated or mapped field, +// because client libraries are not capable of handling such variable expansion. +// +// The path variables **must not** capture the leading "/" character. The reason +// is that the most common use case "{var}" does not capture the leading "/" +// character. For consistency, all path variables must share the same behavior. +// +// Repeated message fields must not be mapped to URL query parameters, because +// no client library can support such complicated mapping. +// +// If an API needs to use a JSON array for request or response body, it can map +// the request or response body to a repeated field.

In case of a REST get operation, the +// field mask applies directly to the response, but in case of a REST +// list operation, the mask instead applies to each individual message +// in the returned resource list. 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. Note that +// a repeated field is only allowed in the last position of a `paths` string. +// +// If a sub-message is specified in the last position of the field mask for an +// update operation, then new value will be merged into the existing sub-message +// in the target resource. +// +// For example, given the target message: +// +// f { +// b { +// d: 1 +// x: 2 +// } +// c: [1] +// } +// +// And an update message: +// +// f { +// b { +// d: 10 +// } +// c: [2] +// } +// +// then if the field mask is: +// +// paths: ["f.b", "f.c"] +// +// then the result will be: +// +// f { +// b { +// d: 10 +// x: 2 +// } +// c: [1, 2] +// } +// +// An implementation may provide options to override this default behavior for +// repeated and message fields. +// +// In order to reset a field's value to the default, the field must +// be in the mask and set to the default value in the provided resource. +// Hence, in order to reset all fields of a resource, provide a default +// instance of the resource and set all fields in the mask, or do +// not provide a mask as described below. +// +// If a field mask is not present on update, the operation applies to +// all fields (as if a field mask of all fields has been specified). +// Note that in the presence of schema evolution, this may mean that +// fields the client does not know and has therefore not filled into +// the request will be reset to their default. 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. Fields name in each path are converted +// to/from lower-camel naming conventions. +// +// As an example, consider the following message declarations: +// +// message Profile { +// User user = 1; +// Photo photo = 2; +// } +// message User { +// string display_name = 1; +// string address = 2; +// } +// +// In proto a field mask for `Profile` may look as such: +// +// mask { +// paths: "user.display_name" +// paths: "photo" +// } +// +// In JSON, the same mask is represented as below: +// +// { +// mask: "user.displayName,photo" +// } +// +// # Field Masks and Oneof Fields +// +// Field masks treat fields in oneofs just as regular fields. Consider the +// following message: +// +// message SampleMessage { +// oneof test_oneof { +// string name = 4; +// SubMessage sub_message = 9; +// } +// } +// +// The field mask can be: +// +// mask { +// paths: "name" +// } +// +// Or: +// +// mask { +// paths: "sub_message" +// } +// +// Note that oneof type names ("test_oneof" in this case) cannot be used in +// paths. +// +// ## Field Mask Verification +// +// The implementation of any API method which has a FieldMask type field in the +// request should verify the included field paths, and return an +// `INVALID_ARGUMENT` error if any path is unmappable. +type FieldMask struct { + state protoimpl.MessageState `protogen:"open.v1"` + // The set of field mask paths. + Paths []string `protobuf:"bytes,1,rep,name=paths,proto3" json:"paths,omitempty"` + unknownFields protoimpl.UnknownFields + sizeCache protoimpl.SizeCache +} + +// New constructs a field mask from a list of paths and verifies that +// each one is valid according to the specified message type. +func New(m proto.Message, paths ...string) (*FieldMask, error) { + x := new(FieldMask) + return x, x.Append(m, paths...) +} + +// Union returns the union of all the paths in the input field masks. +func Union(mx *FieldMask, my *FieldMask, ms ...*FieldMask) *FieldMask { + var out []string + out = append(out, mx.GetPaths()...) + out = append(out, my.GetPaths()...) + for _, m := range ms { + out = append(out, m.GetPaths()...) + } + return &FieldMask{Paths: normalizePaths(out)} +} + +// Intersect returns the intersection of all the paths in the input field masks. +func Intersect(mx *FieldMask, my *FieldMask, ms ...*FieldMask) *FieldMask { + var ss1, ss2 []string // reused buffers for performance + intersect := func(out, in []string) []string { + ss1 = normalizePaths(append(ss1[:0], in...)) + ss2 = normalizePaths(append(ss2[:0], out...)) + out = out[:0] + for i1, i2 := 0, 0;

It uses -lumberjack.log in + // os.TempDir() if empty. + Filename string `json:"filename" yaml:"filename"` + + // MaxSize is the maximum size in megabytes of the log file before it gets + // rotated. It defaults to 100 megabytes. + MaxSize int `json:"maxsize" yaml:"maxsize"` + + // MaxAge is the maximum number of days to retain old log files based on the + // timestamp encoded in their filename. Note that a day is defined as 24 + // hours and may not exactly correspond to calendar days due to daylight + // savings, leap seconds, etc. The default is not to remove old log files + // based on age. + MaxAge int `json:"maxage" yaml:"maxage"` + + // MaxBackups is the maximum number of old log files to retain.

The default is not to perform compression. + Compress bool `json:"compress" yaml:"compress"` + // contains filtered or unexported fields +} +``` +Logger is an io.WriteCloser that writes to the specified filename. + +Logger opens or creates the logfile on first Write. If the file exists and +is less than MaxSize megabytes, lumberjack will open and append to that file. +If the file exists and its size is >= MaxSize megabytes, the file is renamed +by putting the current time in a timestamp in the name immediately before the +file's extension (or the end of the filename if there's no extension). A new +log file is then created using original filename. + +Whenever a write would cause the current log file exceed MaxSize megabytes, +the current file is closed, renamed, and a new log file created with the +original name. Thus, the filename you give Logger is always the "current" log +file. + +Backups use the log file name given to Logger, in the form `name-timestamp.ext` +where name is the filename without the extension, timestamp is the time at which +the log was rotated formatted with the time.Time format of +`2006-01-02T15-04-05.000` and the extension is the original extension. For +example, if your Logger.Filename is `/var/log/foo/server.log`, a backup created +at 6:30pm on Nov 11 2016 would use the filename +`/var/log/foo/server-2016-11-04T18-30-00.000.log` + +### Cleaning Up Old Log Files +Whenever a new logfile gets created, old log files may be deleted. The most +recent files according to the encoded timestamp will be retained, up to a +number equal to MaxBackups (or all of them if MaxBackups is 0). Any files +with an encoded timestamp older than MaxAge days are deleted, regardless of +MaxBackups. Note that the time encoded in the timestamp is the rotation +time, which may differ from the last time that file was written to. + +If MaxBackups and MaxAge are both 0, no old log files will be deleted. + + + + + + + + + + + +### func (\*Logger) Close +``` go +func (l *Logger) Close() error +``` +Close implements io.Closer, and closes the current logfile. + + + +### func (\*Logger) Rotate +``` go +func (l *Logger) Rotate() error +``` +Rotate causes Logger to close the existing log file and immediately create a +new one. This is a helper function for applications that want to initiate +rotations outside of the normal rotation rules, such as in response to +SIGHUP. After rotating, this initiates a cleanup of old log files according +to the normal rules. + +**Example** + +Example of how to rotate in response to SIGHUP. + +Code: + +```go +l := &lumberjack.Logger{} +log.SetOutput(l) +c := make(chan os.Signal, 1) +signal.Notify(c, syscall.SIGHUP) + +go func() { + for { + <-c + l.Rotate() + } +}() +``` + +### func (\*Logger) Write +``` go +func (l *Logger) Write(p []byte) (n int, err error) +``` +Write implements io.Writer. If a write would cause the log file to be larger +than MaxSize, the file is closed, renamed to include a timestamp of the +current time, and a new log file is created using the original log file name. +If the length of the write is greater than MaxSize, an error is returned. + + + + + + + + + +- - - +Generated by [godoc2md](http://godoc.org/github.com/davecheney/godoc2md) diff --git a/vendor/gopkg.in/natefinch/lumberjack.v2/chown.go b/vendor/gopkg.in/natefinch/lumberjack.v2/chown.go new file mode 100644 index 00000000..11d06697 --- /dev/null +++ b/vendor/gopkg.in/natefinch/lumberjack.v2/chown.go @@ -0,0 +1,11 @@ +// +build !linux + +package lumberjack + +import ( + "os" +) + +func chown(_ string, _ os.FileInfo) error { + return nil +} diff --git a/vendor/gopkg.in/natefinch/lumberjack.v2/chown_linux.go b/vendor/gopkg.in/natefinch/lumberjack.v2/chown_linux.go new file mode 100644 index 00000000..465f5692 --- /dev/null +++ b/vendor/gopkg.in/natefinch/lumberjack.v2/chown_linux.go @@ -0,0 +1,19 @@ +package lumberjack + +import ( + "os" + "syscall" +) + +// osChown is a var so we can mock it out during tests. +var osChown = os.Chown + +func chown(name string, info os.FileInfo) error { + f, err := os.OpenFile(name, os.O_CREATE|os.O_WRONLY|os.O_TRUNC, info.Mode()) + if err != nil { + return err + } + f.Close() + stat := info.Sys().(*syscall.Stat_t) + return osChown(name, int(stat.Uid), int(stat.Gid)) +} diff --git a/vendor/gopkg.in/natefinch/lumberjack.v2/lumberjack.go b/vendor/gopkg.in/natefinch/lumberjack.v2/lumberjack.go new file mode 100644 index 00000000..3447cdc0 --- /dev/null +++ b/vendor/gopkg.in/natefinch/lumberjack.v2/lumberjack.go @@ -0,0 +1,541 @@ +// Package lumberjack provides a rolling logger. +// +// Note that this is v2.0 of lumberjack, and should be imported using gopkg.in +// thusly: +// +// import "gopkg.in/natefinch/lumberjack.v2" +// +// The package name remains simply lumberjack, and the code resides at +// https://github.com/natefinch/lumberjack under the v2.0 branch. +// +// Lumberjack is intended to be one part of a logging infrastructure. +// It is not an all-in-one solution, but instead is a pluggable +// component at the bottom of the logging stack that simply controls the files +// to which logs are written. +// +// Lumberjack plays well with any logging package that can write to an +// io.Writer, including the standard library's log package. +// +// Lumberjack assumes that only one process is writing to the output files. +// Using the same lumberjack configuration from multiple processes on the same +// machine will result in improper behavior. +package lumberjack + +import ( + "compress/gzip" + "errors" + "fmt" + "io" + "io/ioutil" + "os" + "path/filepath" + "sort" + "strings" + "sync" + "time" +) + +const ( + backupTimeFormat = "2006-01-02T15-04-05.000" + compressSuffix = ".gz" + defaultMaxSize = 100 +) + +// ensure we always implement io.WriteCloser +var _ io.WriteCloser = (*Logger)(nil) + +// Logger is an io.WriteCloser that writes to the specified filename. +// +// Logger opens or creates the logfile on first Write.

You can find a good paper +// on that at https://dl.acm.org/citation.cfm?doid=75247.75248 or +// http://people.csail.mit.edu/imcgraw/links/research/pubs/networks/WFQ.pdf +// and there is an implementation outline in the Wikipedia article at +// https://en.wikipedia.org/wiki/Fair_queuing . +// +// Fair queuing for server requests differs from traditional fair +// queuing in three ways: (1) we are dispatching application layer +// requests to a server rather than transmitting packets on a network +// link, (2) multiple requests can be executing at once, and (3) the +// service time (execution duration) is not known until the execution +// completes. +// +// The first two differences can easily be handled by straightforward +// adaptation of the concept called "R(t)" in the original paper and +// "virtual time" in the implementation outline. In that +// implementation outline, the notation now() is used to mean reading +// the virtual clock. In the original paper’s terms, "R(t)" is the +// number of "rounds" that have been completed at real time t --- +// where a round consists of virtually transmitting one bit from every +// non-empty queue in the router (regardless of which queue holds the +// packet that is really being transmitted at the moment); in this +// conception, a packet is considered to be "in" its queue until the +// packet’s transmission is finished. For our problem, we can define a +// round to be giving one nanosecond of CPU to every non-empty queue +// in the apiserver (where emptiness is judged based on both queued +// and executing requests from that queue), and define R(t) = (server +// start time) + (1 ns) * (number of rounds since server start). Let +// us write NEQ(t) for that number of non-empty queues in the +// apiserver at time t. Let us also write C for the concurrency +// limit. In the original paper, the partial derivative of R(t) with +// respect to t is +// +// 1 / NEQ(t) . +// +// To generalize from transmitting one packet at a time to executing C +// requests at a time, that derivative becomes +// +// C / NEQ(t) . +// +// However, sometimes there are fewer than C requests available to +// execute. For a given queue "q", let us also write "reqs(q, t)" for +// the number of requests of that queue that are executing at that +// time. The total number of requests executing is sum[over q] +// reqs(q, t) and if that is less than C then virtual time is not +// advancing as fast as it would if all C seats were occupied; in this +// case the numerator of the quotient in that derivative should be +// adjusted proportionally. Putting it all together for fair queing +// for server requests: at a particular time t, the partial derivative +// of R(t) with respect to t is +// +// min( C, sum[over q] reqs(q, t) ) / NEQ(t) . +// +// In terms of the implementation outline, this is the rate at which +// virtual time is advancing at time t (in virtual nanoseconds per +// real nanosecond). Where the networking implementation outline adds +// packet size to a virtual time, in our version this corresponds to +// adding a service time (i.e., duration) to virtual time. +// +// The third difference is handled by modifying the algorithm to +// dispatch based on an initial guess at the request’s service time +// (duration) and then make the corresponding adjustments once the +// request’s actual service time is known. This is similar, although +// not exactly isomorphic, to the original paper’s adjustment by +// `$\delta$` for the sake of promptness. +// +// For implementation simplicity (see below), let us use the same +// initial service time guess for every request; call that duration +// G. A good choice might be the service time limit (1 +// minute). Different guesses will give slightly different dynamics, +// but any positive number can be used for G without ruining the +// long-term behavior. +// +// As in ordinary fair queuing, there is a bound on divergence from +// the ideal. In plain fair queuing the bound is one packet; in our +// version it is C requests. +// +// To support efficiently making the necessary adjustments once a +// request’s actual service time is known, the virtual finish time of +// a request and the last virtual finish time of a queue are not +// represented directly but instead computed from queue length, +// request position in the queue, and an alternate state variable that +// holds the queue’s virtual start time. While the queue is empty and +// has no requests executing: the value of its virtual start time +// variable is ignored and its last virtual finish time is considered +// to be in the virtual past. When a request arrives to an empty queue +// with no requests executing, the queue’s virtual start time is set +// to the current virtual time. The virtual finish time of request +// number J in the queue (counting from J=1 for the head) is J * G + +// (queue's virtual start time). While the queue is non-empty: the +// last virtual finish time of the queue is the virtual finish time of +// the last request in the queue. While the queue is empty and has a +// request executing: the last virtual finish time is the queue’s +// virtual start time. When a request is dequeued for service the +// queue’s virtual start time is advanced by G. When a request +// finishes being served, and the actual service time was S, the +// queue’s virtual start time is decremented by G - S. +package queueset diff --git a/vendor/k8s.io/apiserver/pkg/util/flowcontrol/fairqueuing/queueset/fifo_list.go b/vendor/k8s.io/apiserver/pkg/util/flowcontrol/fairqueuing/queueset/fifo_list.go new file mode 100644 index 00000000..eb56e1e9 --- /dev/null +++ b/vendor/k8s.io/apiserver/pkg/util/flowcontrol/fairqueuing/queueset/fifo_list.go @@ -0,0 +1,156 @@ +/* +Copyright 2021 The Kubernetes Authors. + +Licensed under the Apache License, Version 2.0 (the "License");

Each Apply function takes an "apply +configuration" type as an argument, which is a structured representation of an Apply request. For +example: + + import ( + ... + v1ac "k8s.io/client-go/applyconfigurations/autoscaling/v1" + ) + hpaApplyConfig := v1ac.HorizontalPodAutoscaler(autoscalerName, ns). + WithSpec(v1ac.HorizontalPodAutoscalerSpec(). + WithMinReplicas(0) + ) + return hpav1client.Apply(ctx, hpaApplyConfig, metav1.ApplyOptions{FieldManager: "mycontroller", Force: true}) + +Note in this example that HorizontalPodAutoscaler is imported from an "applyconfigurations" +package. Each "apply configuration" type represents the same Kubernetes object kind as the +corresponding go struct, but where all fields are pointers to make them optional, allowing apply +requests to be accurately represented. For example, this when the apply configuration in the above +example is marshalled to YAML, it produces: + + apiVersion: autoscaling/v1 + kind: HorizontalPodAutoscaler + metadata: + name: myHPA + namespace: myNamespace + spec: + minReplicas: 0 + +To understand why this is needed, the above YAML cannot be produced by the +v1.HorizontalPodAutoscaler go struct. Take for example: + + hpa := v1.HorizontalPodAutoscaler{ + TypeMeta: metav1.TypeMeta{ + APIVersion: "autoscaling/v1", + Kind: "HorizontalPodAutoscaler", + }, + ObjectMeta: ObjectMeta{ + Namespace: ns, + Name: autoscalerName, + }, + Spec: v1.HorizontalPodAutoscalerSpec{ + MinReplicas: pointer.Int32Ptr(0), + }, + } + +The above code attempts to declare the same apply configuration as shown in the previous examples, +but when marshalled to YAML, produces: + + kind: HorizontalPodAutoscaler + apiVersion: autoscaling/v1 + metadata: + name: myHPA + namespace: myNamespace + spec: + scaleTargetRef: + kind: "" + name: "" + minReplicas: 0 + maxReplicas: 0 + +Which, among other things, contains spec.maxReplicas set to 0. This is almost certainly not what +the caller intended (the intended apply configuration says nothing about the maxReplicas field), +and could have serious consequences on a production system: it directs the autoscaler to downscale +to zero pods. The problem here originates from the fact that the go structs contain required fields +that are zero valued if not set explicitly. The go structs work as intended for create and update +operations, but are fundamentally incompatible with apply, which is why we have introduced the +generated "apply configuration" types. + +The "apply configurations" also have convenience With functions that make it easier to +build apply requests. This allows developers to set fields without having to deal with the fact that +all the fields in the "apply configuration" types are pointers, and are inconvenient to set using +go. For example "MinReplicas: &0" is not legal go code, so without the With functions, developers +would work around this problem by using a library, .e.g. "MinReplicas: pointer.Int32Ptr(0)", but +string enumerations like corev1.Protocol are still a problem since they cannot be supported by a +general purpose library. In addition to the convenience, the With functions also isolate +developers from the underlying representation, which makes it safer for the underlying +representation to be changed to support additional features in the future. + +# Controller Support + +The new client-go support makes it much easier to use Server-side Apply in controllers, by either of +two mechanisms. + +Mechanism 1: + +When authoring new controllers to use Server-side Apply, a good approach is to have the controller +recreate the apply configuration for an object each time it reconciles that object. This ensures +that the controller fully reconciles all the fields that it is responsible for. Controllers +typically should unconditionally set all the fields they own by setting "Force: true" in the +ApplyOptions. Controllers must also provide a FieldManager name that is unique to the +reconciliation loop that apply is called from. + +When upgrading existing controllers to use Server-side Apply the same approach often works +well--migrate the controllers to recreate the apply configuration each time it reconciles any +object. For cases where this does not work well, see Mechanism 2. + +Mechanism 2: + +When upgrading existing controllers to use Server-side Apply, the controller might have multiple +code paths that update different parts of an object depending on various conditions. Migrating a +controller like this to Server-side Apply can be risky because if the controller forgets to include +any fields in an apply configuration that is included in a previous apply request, a field can be +accidentally deleted. For such cases, an alternative to mechanism 1 is to replace any controller +reconciliation code that performs a "read/modify-in-place/update" (or patch) workflow with a +"extract/modify-in-place/apply" workflow. Here's an example of the new workflow: + + fieldMgr := "my-field-manager" + deploymentClient := clientset.AppsV1().Deployments("default") + // read, could also be read from a shared informer + deployment, err := deploymentClient.Get(ctx, "example-deployment", metav1.GetOptions{}) + if err != nil { + // handle error + } + // extract + deploymentApplyConfig, err := appsv1ac.ExtractDeployment(deployment, fieldMgr) + if err != nil { + // handle error + } + // modify-in-place + deploymentApplyConfig.Spec.Template.Spec.WithContainers(corev1ac.Container(). + WithName("modify-slice"). + WithImage("nginx:1.14.2"), + ) + // apply + applied, err := deploymentClient.Apply(ctx, extractedDeployment, metav1.ApplyOptions{FieldManager: fieldMgr}) +*/ +package applyconfigurations diff --git a/vendor/k8s.io/client-go/applyconfigurations/imagepolicy/v1alpha1/imagereview.go b/vendor/k8s.io/client-go/applyconfigurations/imagepolicy/v1alpha1/imagereview.go new file mode 100644 index 00000000..f63c86ce --- /dev/null +++ b/vendor/k8s.io/client-go/applyconfigurations/imagepolicy/v1alpha1/imagereview.go @@ -0,0 +1,291 @@ +/* +Copyright The Kubernetes 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. +*/ + +// Code generated by applyconfiguration-gen.
