Listeners define - logical endpoints that are bound on this Gateway's addresses. At - least one Listener MUST be specified. \n Each Listener in a set - of Listeners (for example, in a single Gateway) MUST be _distinct_, - in that a traffic flow MUST be able to be assigned to exactly one - listener. (This section uses \"set of Listeners\" rather than \"Listeners - in a single Gateway\" because implementations MAY merge configuration - from multiple Gateways onto a single data plane, and these rules - _also_ apply in that case). \n Practically, this means that each - listener in a set MUST have a unique combination of Port, Protocol, - and, if supported by the protocol, Hostname. \n Some combinations - of port, protocol, and TLS settings are considered Core support - and MUST be supported by implementations based on their targeted - conformance profile: \n HTTP Profile \n 1. HTTPRoute, Port: 80, - Protocol: HTTP 2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: - Terminate, TLS keypair provided \n TLS Profile \n 1. TLSRoute, Port: - 443, Protocol: TLS, TLS Mode: Passthrough \n \"Distinct\" Listeners - have the following property: \n The implementation can match inbound - requests to a single distinct Listener. When multiple Listeners - share values for fields (for example, two Listeners with the same - Port value), the implementation can match requests to only one of - the Listeners using other Listener fields. \n For example, the following - Listener scenarios are distinct: \n 1. Multiple Listeners with the - same Port that all use the \"HTTP\" Protocol that all have unique - Hostname values. 2. Multiple Listeners with the same Port that use - either the \"HTTPS\" or \"TLS\" Protocol that all have unique Hostname - values. 3. A mixture of \"TCP\" and \"UDP\" Protocol Listeners, - where no Listener with the same Protocol has the same Port value. - \n Some fields in the Listener struct have possible values that - affect whether the Listener is distinct. Hostname is particularly - relevant for HTTP or HTTPS protocols. \n When using the Hostname - value to select between same-Port, same-Protocol Listeners, the - Hostname value must be different on each Listener for the Listener - to be distinct. \n When the Listeners are distinct based on Hostname, - inbound request hostnames MUST match from the most specific to least - specific Hostname values to choose the correct Listener and its - associated set of Routes. \n Exact matches must be processed before - wildcard matches, and wildcard matches must be processed before - fallback (empty Hostname value) matches. For example, `\"foo.example.com\"` - takes precedence over `\"*.example.com\"`, and `\"*.example.com\"` - takes precedence over `\"\"`. \n Additionally, if there are multiple - wildcard entries, more specific wildcard entries must be processed - before less specific wildcard entries. For example, `\"*.foo.example.com\"` - takes precedence over `\"*.example.com\"`. The precise definition - here is that the higher the number of dots in the hostname to the - right of the wildcard character, the higher the precedence. \n The - wildcard character will match any number of characters _and dots_ - to the left, however, so `\"*.example.com\"` will match both `\"foo.bar.example.com\"` - _and_ `\"bar.example.com\"`. \n If a set of Listeners contains Listeners - that are not distinct, then those Listeners are Conflicted, and - the implementation MUST set the \"Conflicted\" condition in the - Listener Status to \"True\". \n Implementations MAY choose to accept - a Gateway with some Conflicted Listeners only if they only accept - the partial Listener set that contains no Conflicted Listeners. - To put this another way, implementations may accept a partial Listener - set only if they throw out *all* the conflicting Listeners. No picking - one of the conflicting listeners as the winner. This also means - that the Gateway must have at least one non-conflicting Listener - in this case, otherwise it violates the requirement that at least - one Listener must be present. \n The implementation MUST set a \"ListenersNotValid\" - condition on the Gateway Status when the Gateway contains Conflicted - Listeners whether or not they accept the Gateway. That Condition - SHOULD clearly indicate in the Message which Listeners are conflicted, - and which are Accepted. Additionally, the Listener status for those - listeners SHOULD indicate which Listeners are conflicted and not - Accepted. \n A Gateway's Listeners are considered \"compatible\" - if: \n 1. They are distinct. 2. The implementation can serve them - in compliance with the Addresses requirement that all Listeners - are available on all assigned addresses. \n Compatible combinations - in Extended support are expected to vary across implementations. - A combination that is compatible for one implementation may not - be compatible for another. \n For example, an implementation that - cannot serve both TCP and UDP listeners on the same address, or - cannot mix HTTPS and generic TLS listens on the same port would - not consider those cases compatible, even though they are distinct. - \n Note that requests SHOULD match at most one Listener. For example, - if Listeners are defined for \"foo.example.com\" and \"*.example.com\", - a request to \"foo.example.com\" SHOULD only be routed using routes - attached to the \"foo.example.com\" Listener (and not the \"*.example.com\" - Listener).

(This section uses \"set of Listeners\" rather than \"Listeners - in a single Gateway\" because implementations MAY merge configuration - from multiple Gateways onto a single data plane, and these rules - _also_ apply in that case). \n Practically, this means that each - listener in a set MUST have a unique combination of Port, Protocol, - and, if supported by the protocol, Hostname. \n Some combinations - of port, protocol, and TLS settings are considered Core support - and MUST be supported by implementations based on their targeted - conformance profile: \n HTTP Profile \n 1. HTTPRoute, Port: 80, - Protocol: HTTP 2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: - Terminate, TLS keypair provided \n TLS Profile \n 1.

When multiple Listeners - share values for fields (for example, two Listeners with the same - Port value), the implementation can match requests to only one of - the Listeners using other Listener fields. \n For example, the following - Listener scenarios are distinct: \n 1. Multiple Listeners with the - same Port that all use the \"HTTP\" Protocol that all have unique - Hostname values. 2. Multiple Listeners with the same Port that use - either the \"HTTPS\" or \"TLS\" Protocol that all have unique Hostname - values. 3. A mixture of \"TCP\" and \"UDP\" Protocol Listeners, - where no Listener with the same Protocol has the same Port value. - \n Some fields in the Listener struct have possible values that - affect whether the Listener is distinct. Hostname is particularly - relevant for HTTP or HTTPS protocols. \n When using the Hostname - value to select between same-Port, same-Protocol Listeners, the - Hostname value must be different on each Listener for the Listener - to be distinct. \n When the Listeners are distinct based on Hostname, - inbound request hostnames MUST match from the most specific to least - specific Hostname values to choose the correct Listener and its - associated set of Routes. \n Exact matches must be processed before - wildcard matches, and wildcard matches must be processed before - fallback (empty Hostname value) matches. For example, `\"foo.example.com\"` - takes precedence over `\"*.example.com\"`, and `\"*.example.com\"` - takes precedence over `\"\"`. \n Additionally, if there are multiple - wildcard entries, more specific wildcard entries must be processed - before less specific wildcard entries. For example, `\"*.foo.example.com\"` - takes precedence over `\"*.example.com\"`. The precise definition - here is that the higher the number of dots in the hostname to the - right of the wildcard character, the higher the precedence. \n The - wildcard character will match any number of characters _and dots_ - to the left, however, so `\"*.example.com\"` will match both `\"foo.bar.example.com\"` - _and_ `\"bar.example.com\"`. \n If a set of Listeners contains Listeners - that are not distinct, then those Listeners are Conflicted, and - the implementation MUST set the \"Conflicted\" condition in the - Listener Status to \"True\". \n Implementations MAY choose to accept - a Gateway with some Conflicted Listeners only if they only accept - the partial Listener set that contains no Conflicted Listeners. - To put this another way, implementations may accept a partial Listener - set only if they throw out *all* the conflicting Listeners. No picking - one of the conflicting listeners as the winner. This also means - that the Gateway must have at least one non-conflicting Listener - in this case, otherwise it violates the requirement that at least - one Listener must be present. \n The implementation MUST set a \"ListenersNotValid\" - condition on the Gateway Status when the Gateway contains Conflicted - Listeners whether or not they accept the Gateway. That Condition - SHOULD clearly indicate in the Message which Listeners are conflicted, - and which are Accepted. Additionally, the Listener status for those - listeners SHOULD indicate which Listeners are conflicted and not - Accepted. \n A Gateway's Listeners are considered \"compatible\" - if: \n 1. They are distinct. 2. The implementation can serve them - in compliance with the Addresses requirement that all Listeners - are available on all assigned addresses. \n Compatible combinations - in Extended support are expected to vary across implementations. - A combination that is compatible for one implementation may not - be compatible for another. \n For example, an implementation that - cannot serve both TCP and UDP listeners on the same address, or - cannot mix HTTPS and generic TLS listens on the same port would - not consider those cases compatible, even though they are distinct. - \n Note that requests SHOULD match at most one Listener. For example, - if Listeners are defined for \"foo.example.com\" and \"*.example.com\", - a request to \"foo.example.com\" SHOULD only be routed using routes - attached to the \"foo.example.com\" Listener (and not the \"*.example.com\" - Listener). This concept is known as \"Listener Isolation\".

For example, `"foo.example.com"` takes precedence over + `"*.example.com"`, and `"*.example.com"` takes precedence over `""`. + + + Additionally, if there are multiple wildcard entries, more specific + wildcard entries must be processed before less specific wildcard entries. + For example, `"*.foo.example.com"` takes precedence over `"*.example.com"`. + The precise definition here is that the higher the number of dots in the + hostname to the right of the wildcard character, the higher the precedence. + + + The wildcard character will match any number of characters _and dots_ to + the left, however, so `"*.example.com"` will match both + `"foo.bar.example.com"` _and_ `"bar.example.com"`. + + + If a set of Listeners contains Listeners that are not distinct, then those + Listeners are Conflicted, and the implementation MUST set the "Conflicted" + condition in the Listener Status to "True". + + + Implementations MAY choose to accept a Gateway with some Conflicted + Listeners only if they only accept the partial Listener set that contains + no Conflicted Listeners.

That Condition SHOULD clearly + indicate in the Message which Listeners are conflicted, and which are + Accepted. Additionally, the Listener status for those listeners SHOULD + indicate which Listeners are conflicted and not Accepted. + + + A Gateway's Listeners are considered "compatible" if: + + + 1.

For example, if + Listeners are defined for "foo.example.com" and "*.example.com", a + request to "foo.example.com" SHOULD only be routed using routes attached + to the "foo.example.com" Listener (and not the "*.example.com" Listener). + This concept is known as "Listener Isolation".

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

It is not +intended to be general-purpose and makes some assumptions that may not hold +outside of Kubernetes. + +In the past this repo was partially supported for external use (outside of the +Kubernetes project overall), but that is no longer true. We may change the API +in incompatible ways, without warning. + +If you are not building something that is part of Kubernetes, DO NOT DEPEND ON +THIS REPO. + +## New usage within Kubernetes + +Gengo is a very opinionated framework. It is primarily aimed at generating Go +code derived from types defined in other Go code, but it is possible to use it +for other things (e.g. proto files). Net new tools should consider using +`golang.org/x/tools/go/packages` directly. Gengo can serve as an example of +how to do that. + +If you still decide you want to use gengo, see the +[simple examples](./examples) in this repo or the more extensive tools in the +Kubernetes [code-generator](https://github.com/kubernetes/code-generator/) +repo. + +## Overview + +Gengo is used to build tools (generally a tool is a binary). Each tool +describes some number of `Targets`. A target is a single output package, which +may be the same as the inputs (if the tool generates code alongside the inputs) +or different. Each `Target` describes some number of `Generators`. A +generator is responsible for emitting a single file into the target directory. + +Gengo helps the tool to load and process input packages, e.g. extracting type +information and associating comments. Each target will be offered every known +type, and can filter that down to the set of types it cares about. Each +generator will be offered the result of the target's filtering, and can filter +the set of types further. Finally, the generator will be called to emit code +for all of the remaining types. + +The `tracer` example in this repo can be used to examine all of the hooks. + +## Contributing + +Please see [CONTRIBUTING.md](CONTRIBUTING.md) for instructions on how to contribute. diff --git a/vendor/k8s.io/gengo/v2/comments.go b/vendor/k8s.io/gengo/v2/comments.go new file mode 100644 index 000000000..ba49c432b --- /dev/null +++ b/vendor/k8s.io/gengo/v2/comments.go @@ -0,0 +1,83 @@ +/* +Copyright 2015 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. +*/ + +package gengo + +import ( + "fmt" + "strings" +) + +// ExtractCommentTags parses comments for lines of the form: +// +// 'marker' + "key=value". +// +// Values are optional; "" is the default.

E.g., if the type is "string" this might +// return "String". +// - the second "$" ends the template directive. +// +// The map is actually not necessary. The below does the same thing: +// +// sw.Do(`The public type name is: $.|public$`, t) +// +// You may or may not find it more readable to use the map with a descriptive +// key, but if you want to pass more than one arg, the map or a custom struct +// becomes a requirement. You can do arbitrary logic inside these templates, +// but you should consider doing the logic in go and stitching them together +// for the sake of your readers. +// +// TODO: Change Do() to optionally take a list of pairs of parameters (key, value) +// and have it construct a combined map with that and args. +func (s *SnippetWriter) Do(format string, args interface{}) *SnippetWriter { + if s.err != nil { + return s + } + // Name the template by source file:line so it can be found when + // there's an error. + _, file, line, _ := runtime.Caller(1) + tmpl, err := template. + New(fmt.Sprintf("%s:%d", file, line)). + Delims(s.left, s.right). + Funcs(s.funcMap). + Parse(format) + if err != nil { + s.err = err + return s + } + err = tmpl.Execute(s.w, args) + if err != nil { + s.err = err + } + return s +} + +// Args exists to make it convenient to construct arguments for +// SnippetWriter.Do. +type Args map[interface{}]interface{} + +// With makes a copy of a and adds the given key, value pair. +func (a Args) With(key, value interface{}) Args { + a2 := Args{key: value} + for k, v := range a { + a2[k] = v + } + return a2 +} + +// WithArgs makes a copy of a and adds the given arguments. +func (a Args) WithArgs(rhs Args) Args { + a2 := Args{} + for k, v := range rhs { + a2[k] = v + } + for k, v := range a { + a2[k] = v + } + return a2 +} + +func (s *SnippetWriter) Out() io.Writer { + return s.w +} + +// Error returns any encountered error. +func (s *SnippetWriter) Error() error { + return s.err +} diff --git a/vendor/k8s.io/gengo/v2/namer/doc.go b/vendor/k8s.io/gengo/v2/namer/doc.go new file mode 100644 index 000000000..76309ebb0 --- /dev/null +++ b/vendor/k8s.io/gengo/v2/namer/doc.go @@ -0,0 +1,31 @@ +/* +Copyright 2015 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. +*/ + +// Package namer has support for making different type naming systems. +// +// This is because sometimes you want to refer to the literal type, sometimes +// you want to make a name for the thing you're generating, and you want to +// make the name based on the type.
