I +really appreciate what he has to say, and it largely aligns with my own +experiences. Too many choices of levels means inconsistent logs. + +This package offers a purely abstract interface, based on these ideas but with +a few twists. Code can depend on just this interface and have the actual +logging implementation be injected from callers. Ideally only `main()` knows +what logging implementation is being used. + +# Differences from Dave's ideas + +The main differences are: + +1) Dave basically proposes doing away with the notion of a logging API in favor +of `fmt.Printf()`. I disagree, especially when you consider things like output +locations, timestamps, file and line decorations, and structured logging. I +restrict the API to just 2 types of logs: info and error. + +Info logs are things you want to tell the user which are not errors. Error +logs are, well, errors. If your code receives an `error` from a subordinate +function call and is logging that `error` *and not returning it*, use error +logs. + +2) Verbosity-levels on info logs. This gives developers a chance to indicate +arbitrary grades of importance for info logs, without assigning names with +semantic meaning such as "warning", "trace", and "debug". Superficially this +may feel very similar, but the primary difference is the lack of semantics. +Because verbosity is a numerical value, it's safe to assume that an app running +with higher verbosity means more (and less important) logs will be generated. + +This is a BETA grade API. I have implemented it for +[glog](https://godoc.org/github.com/golang/glog).

Loggers can have name prefixes and named values +// attached, so that all log messages logged with that Logger have some base context +// associated. +// +// The term "key" is used to refer to the name associated with a particular value, to +// disambiguate it from the general Logger name. +// +// For instance, suppose we're trying to reconcile the state of an object, and we want +// to log that we've made some decision. +// +// With the traditional log package, we might write +// log.Printf( +// "decided to set field foo to value %q for object %s/%s", +// targetValue, object.Namespace, object.Name) +// +// With logr's structured logging, we'd write +// // elsewhere in the file, set up the logger to log with the prefix of "reconcilers", +// // and the named value target-type=Foo, for extra context. +// log := mainLogger.WithName("reconcilers").WithValues("target-type", "Foo") +// +// // later on... +// log.Info("setting field foo on object", "value", targetValue, "object", object) +// +// Depending on our logging implementation, we could then make logging decisions based on field values +// (like only logging such events for objects in a certain namespace), or copy the structured +// information into a structured log store. +// +// For logging errors, Logger has a method called Error. Suppose we wanted to log an +// error while reconciling. With the traditional log package, we might write +// log.Errorf("unable to reconcile object %s/%s: %v", object.Namespace, object.Name, err) +// +// With logr, we'd instead write +// // assuming the above setup for log +// log.Error(err, "unable to reconcile object", "object", object) +// +// This functions similarly to: +// log.Info("unable to reconcile object", "error", err, "object", object) +// +// However, it ensures that a standard key for the error value ("error") is used across all +// error logging. Furthermore, certain implementations may choose to attach additional +// information (such as stack traces) on calls to Error, so it's preferred to use Error +// to log errors. +// +// Parts of a log line +// +// Each log message from a Logger has four types of context: +// logger name, log verbosity, log message, and the named values. +// +// The Logger name constists of a series of name "segments" added by successive calls to WithName. +// These name segments will be joined in some way by the underlying implementation. It is strongly +// reccomended that name segements contain simple identifiers (letters, digits, and hyphen), and do +// not contain characters that could muddle the log output or confuse the joining operation (e.g. +// whitespace, commas, periods, slashes, brackets, quotes, etc). +// +// Log verbosity represents how little a log matters. Level zero, the default, matters most. +// Increasing levels matter less and less. Try to avoid lots of different verbosity levels, +// and instead provide useful keys, logger names, and log messages for users to filter on. +// It's illegal to pass a log level below zero. +// +// The log message consists of a constant message attached to the the log line. This +// should generally be a simple description of what's occuring, and should never be a format string. +// +// Variable information can then be attached using named values (key/value pairs). Keys are arbitrary +// strings, while values may be any Go value. +// +// Key Naming Conventions +// +// While users are generally free to use key names of their choice, it's generally best to avoid +// using the following keys, as they're frequently used by implementations: +// +// - `"error"`: the underlying error value in the `Error` method. +// - `"stacktrace"`: the stack trace associated with a particular log line or error +// (often from the `Error` message). +// - `"caller"`: the calling information (file/line) of a particular log line. +// - `"msg"`: the log message. +// - `"level"`: the log level. +// - `"ts"`: the timestamp for a log line. +// +// Implementations are encouraged to make use of these keys to represent the above +// concepts, when neccessary (for example, in a pure-JSON output form, it would be +// necessary to represent at least message and timestamp as ordinary named values). +package logr + +// TODO: consider adding back in format strings if they're really needed +// TODO: consider other bits of zap/zapcore functionality like ObjectMarshaller (for arbitrary objects) +// TODO: consider other bits of glog functionality like Flush, InfoDepth, OutputStats + +// InfoLogger represents the ability to log non-error messages, at a particular verbosity. +type InfoLogger interface { + // Info logs a non-error message with the given key/value pairs as context. + // + // The msg argument should be used to add some constant description to + // the log line.

For example, +the `fs.BuddyInfo()` function reads the file `/proc/buddyinfo`. In addition, the godoc for each public function +should contain the path to the file(s) being read and a URL of the linux kernel documentation describing the file(s). + +### Reading vs. Parsing + +Most functionality in this library consists of reading files and then parsing the text into structured data. In most +cases reading and parsing should be separated into different functions/methods with a public `fs.Thing()` method and +a private `parseThing(r Reader)` function. This provides a logical separation and allows parsing to be tested +directly without the need to read from the filesystem. Using a `Reader` argument is preferred over other data types +such as `string` or `*File` because it provides the most flexibility regarding the data source. When a set of files +in a directory needs to be parsed, then a `path` string parameter to the parse function can be used instead. + +### /proc and /sys filesystem I/O + +The `proc` and `sys` filesystems are pseudo file systems and work a bit differently from standard disk I/O. +Many of the files are changing continuously and the data being read can in some cases change between subsequent +reads in the same file. Also, most of the files are relatively small (less than a few KBs), and system calls +to the `stat` function will often return the wrong size. Therefore, for most files it's recommended to read the +full file in a single operation using an internal utility function called `util.ReadFileNoStat`. +This function is similar to `ioutil.ReadFile`, but it avoids the system call to `stat` to get the current size of +the file. + +Note that parsing the file's contents can still be performed one line at a time. This is done by first reading +the full file, and then using a scanner on the `[]byte` or `string` containing the data. + +``` + data, err := util.ReadFileNoStat("/proc/cpuinfo") + if err != nil { + return err + } + reader := bytes.NewReader(data) + scanner := bufio.NewScanner(reader) +``` + +The `/sys` filesystem contains many very small files which contain only a single numeric or text value. These files +can be read using an internal function called `util.SysReadFile` which is similar to `ioutil.ReadFile` but does +not bother to check the size of the file before reading. +``` + data, err := util.SysReadFile("/sys/class/power_supply/BAT0/capacity") +``` + diff --git a/vendor/github.com/prometheus/procfs/Makefile.common b/vendor/github.com/prometheus/procfs/Makefile.common index d7aea1b86f..b978dfc50d 100644 --- a/vendor/github.com/prometheus/procfs/Makefile.common +++ b/vendor/github.com/prometheus/procfs/Makefile.common @@ -69,12 +69,21 @@ else GO_BUILD_PLATFORM ?= $(GOHOSTOS)-$(GOHOSTARCH) endif -PROMU_VERSION ?= 0.4.0 +GOTEST := $(GO) test +GOTEST_DIR := +ifneq ($(CIRCLE_JOB),) +ifneq ($(shell which gotestsum),) + GOTEST_DIR := test-results + GOTEST := gotestsum --junitfile $(GOTEST_DIR)/unit-tests.xml -- +endif +endif + +PROMU_VERSION ?= 0.5.0 PROMU_URL := https://github.com/prometheus/promu/releases/download/v$(PROMU_VERSION)/promu-$(PROMU_VERSION).$(GO_BUILD_PLATFORM).tar.gz GOLANGCI_LINT := GOLANGCI_LINT_OPTS ?= -GOLANGCI_LINT_VERSION ?= v1.16.0 +GOLANGCI_LINT_VERSION ?= v1.18.0 # golangci-lint only supports linux, darwin and windows platforms on i386/amd64. # windows isn't included here because of the path separator being different. ifeq ($(GOHOSTOS),$(filter $(GOHOSTOS),linux darwin)) @@ -86,7 +95,8 @@ endif PREFIX ?= $(shell pwd) BIN_DIR ?= $(shell pwd) DOCKER_IMAGE_TAG ?= $(subst /,-,$(shell git rev-parse --abbrev-ref HEAD)) -DOCKERFILE_PATH ?= ./ +DOCKERFILE_PATH ?= ./Dockerfile +DOCKERBUILD_CONTEXT ?= ./ DOCKER_REPO ?= prom DOCKER_ARCHS ?= amd64 @@ -141,14 +151,17 @@ else endif .PHONY: common-test-short -common-test-short: +common-test-short: $(GOTEST_DIR) @echo ">> running short tests" - GO111MODULE=$(GO111MODULE) $(GO) test -short $(GOOPTS) $(pkgs) + GO111MODULE=$(GO111MODULE) $(GOTEST) -short $(GOOPTS) $(pkgs) .PHONY: common-test -common-test: +common-test: $(GOTEST_DIR) @echo ">> running all tests" - GO111MODULE=$(GO111MODULE) $(GO) test $(test-flags) $(GOOPTS) $(pkgs) + GO111MODULE=$(GO111MODULE) $(GOTEST) $(test-flags) $(GOOPTS) $(pkgs) + +$(GOTEST_DIR): + @mkdir -p $@ .PHONY: common-format common-format: @@ -200,7 +213,7 @@ endif .PHONY: common-build common-build: promu @echo ">> building binaries" - GO111MODULE=$(GO111MODULE) $(PROMU) build --prefix $(PREFIX) + GO111MODULE=$(GO111MODULE) $(PROMU) build --prefix $(PREFIX) $(PROMU_BINARIES) .PHONY: common-tarball common-tarball: promu @@ -211,9 +224,10 @@ common-tarball: promu common-docker: $(BUILD_DOCKER_ARCHS) $(BUILD_DOCKER_ARCHS): common-docker-%: docker build -t "$(DOCKER_REPO)/$(DOCKER_IMAGE_NAME)-linux-$*:$(DOCKER_IMAGE_TAG)" \ + -f $(DOCKERFILE_PATH) \ --build-arg ARCH="$*" \ --build-arg OS="linux" \ - $(DOCKERFILE_PATH) + $(DOCKERBUILD_CONTEXT) .PHONY: common-docker-publish $(PUBLISH_DOCKER_ARCHS) common-docker-publish: $(PUBLISH_DOCKER_ARCHS) diff --git a/vendor/github.com/prometheus/procfs/README.md b/vendor/github.com/prometheus/procfs/README.md index 6f8850feb6..55d1e3261c 100644 --- a/vendor/github.com/prometheus/procfs/README.md +++ b/vendor/github.com/prometheus/procfs/README.md @@ -1,6 +1,6 @@ # procfs -This procfs package provides functions to retrieve system, kernel and process +This package provides functions to retrieve system, kernel, and process metrics from the pseudo-filesystems /proc and /sys. *WARNING*: This package is a work in progress.

An example: - -``` -// old -type Point struct { X, Y int } - -// new -type Point struct { X, Y, Z int } - -// client -p := pkg.Point{1, 2} // fails in new because there are more fields than expressions -``` -Here and below, we provide three snippets: the code in the old version of the -package, the code in the new version, and the code written in a client of the package, -which refers to it by the name `pkg`. The client code compiles against the old -code but not the new. - -### Embedding and Shadowing - -Adding an exported field to a struct can break code that embeds that struct, -because the newly added field may conflict with an identically named field -at the same struct depth. A selector referring to the latter would become -ambiguous and thus erroneous. - - -``` -// old -type Point struct { X, Y int } - -// new -type Point struct { X, Y, Z int } - -// client -type z struct { Z int } - -var v struct { - pkg.Point - z -} - -_ = v.Z // fails in new -``` -In the new version, the last line fails to compile because there are two embedded `Z` -fields at the same depth, one from `z` and one from `pkg.Point`. - - -### Using an Identical Type Externally - -If it is possible for client code to write a type expression representing the -underlying type of a defined type in a package, then external code can use it in -assignments involving the package type, making any change to that type incompatible. -``` -// old -type Point struct { X, Y int } - -// new -type Point struct { X, Y, Z int } - -// client -var p struct { X, Y int } = pkg.Point{} // fails in new because of Point's extra field -``` -Here, the external code could have used the provided name `Point`, but chose not -to. I'll have more to say about this and related examples later. - -### unsafe.Sizeof and Friends - -Since `unsafe.Sizeof`, `unsafe.Offsetof` and `unsafe.Alignof` are constant -expressions, they can be used in an array type literal: - -``` -// old -type S struct{ X int } - -// new -type S struct{ X, y int } - -// client -var a [unsafe.Sizeof(pkg.S{})]int = [8]int{} // fails in new because S's size is not 8 -``` -Use of these operations could make many changes to a type potentially incompatible. - - -### Type Switches - -A package change that merges two different types (with same underlying type) -into a single new type may break type switches in clients that refer to both -original types: - -``` -// old -type T1 int -type T2 int - -// new -type T1 int -type T2 = T1 - -// client -switch x.(type) { -case T1: -case T2: -} // fails with new because two cases have the same type -``` -This sort of incompatibility is sufficiently esoteric to ignore; the tool allows -merging types. - -## First Attempt at a Definition - -Our first attempt at defining compatibility captures the idea that all the -exported names in the old package must have compatible equivalents in the new -package. - -A new package is compatible with an old one if and only if: -- For every exported package-level name in the old package, the same name is - declared in the new at package level, and -- the names denote the same kind of object (e.g. both are variables), and -- the types of the objects are compatible. - -We will work out the details (and make some corrections) below, but it is clear -already that we will need to determine what makes two types compatible. And -whatever the definition of type compatibility, it's certainly true that if two -types are the same, they are compatible. So we will need to decide what makes an -old and new type the same. We will call this sameness relation _correspondence_. - -## Type Correspondence - -Go already has a definition of when two types are the same: -[type identity](https://golang.org/ref/spec#Type_identity). -But identity isn't adequate for our purpose: it says that two defined -types are identical if they arise from the same definition, but it's unclear -what "same" means when talking about two different packages (or two versions of -a single package). - -The obvious change to the definition of identity is to require that old and new -[defined types](https://golang.org/ref/spec#Type_definitions) -have the same name instead. But that doesn't work either, for two -reasons. First, type aliases can equate two defined types with different names: - -``` -// old -type E int - -// new -type t int -type E = t -``` -Second, an unexported type can be renamed: - -``` -// old -type u1 int -var V u1 - -// new -type u2 int -var V u2 -``` -Here, even though `u1` and `u2` are unexported, their exported fields and -methods are visible to clients, so they are part of the API. But since the name -`u1` is not visible to clients, it can be changed compatibly. We say that `u1` -and `u2` are _exposed_: a type is exposed if a client package can declare variables of that type. - -We will say that an old defined type _corresponds_ to a new one if they have the -same name, or one can be renamed to the other without otherwise changing the -API. In the first example above, old `E` and new `t` correspond. In the second, -old `u1` and new `u2` correspond. - -Two or more old defined types can correspond to a single new type: we consider -"merging" two types into one to be a compatible change. As mentioned above, -code that uses both names in a type switch will fail, but we deliberately ignore -this case. However, a single old type can correspond to only one new type. - -So far, we've explained what correspondence means for defined types. To extend -the definition to all types, we parallel the language's definition of type -identity. So, for instance, an old and a new slice type correspond if their -element types correspond. - -## Definition of Compatibility - -We can now present the definition of compatibility used by `apidiff`. - -### Package Compatibility - -> A new package is compatible with an old one if: ->1. Each exported name in the old package's scope also appears in the new ->package's scope, and the object (constant, variable, function or type) denoted ->by that name in the old package is compatible with the object denoted by the ->name in the new package, and ->2. For every exposed type that implements an exposed interface in the old package, -> its corresponding type should implement the corresponding interface in the new package. -> ->Otherwise the packages are incompatible. - -As an aside, the tool also finds exported names in the new package that are not -exported in the old, and marks them as compatible changes. - -Clause 2 is discussed further in "Whole-Package Compatibility." - -### Object Compatibility - -This section provides compatibility rules for constants, variables, functions -and types. - -#### Constants - ->A new exported constant is compatible with an old one of the same name if and only if ->1. Their types correspond, and ->2. Their values are identical. - -It is tempting to allow changing a typed constant to an untyped one. That may -seem harmless, but it can break code like this: - -``` -// old -const C int64 = 1 - -// new -const C = 1 - -// client -var x = C // old type is int64, new is int -var y int64 = x // fails with new: different types in assignment -``` - -A change to the value of a constant can break compatibility if the value is used -in an array type: - -``` -// old -const C = 1 - -// new -const C = 2 - -// client -var a [C]int = [1]int{} // fails with new because [2]int and [1]int are different types -``` -Changes to constant values are rare, and determining whether they are compatible -or not is better left to the user, so the tool reports them. - -#### Variables - ->A new exported variable is compatible with an old one of the same name if and ->only if their types correspond. - -Correspondence doesn't look past names, so this rule does not prevent adding a -field to `MyStruct` if the package declares `var V MyStruct`. It does, however, mean that - -``` -var V struct { X int } -``` -is incompatible with -``` -var V struct { X, Y int } -``` -I discuss this at length below in the section "Compatibility, Types and Names." - -#### Functions - ->A new exported function or variable is compatible with an old function of the ->same name if and only if their types (signatures) correspond. - -This rule captures the fact that, although many signature changes are compatible -for all call sites, none are compatible for assignment: - -``` -var v func(int) = pkg.F -``` -Here, `F` must be of type `func(int)` and not, for instance, `func(...int)` or `func(interface{})`. - -Note that the rule permits changing a function to a variable. This is a common -practice, usually done for test stubbing, and cannot break any code at compile -time. - -#### Exported Types - -> A new exported type is compatible with an old one if and only if their -> names are the same and their types correspond. - -This rule seems far too strict. But, ignoring aliases for the moment, it demands only -that the old and new _defined_ types correspond. Consider: -``` -// old -type T struct { X int } - -// new -type T struct { X, Y int } -``` -The addition of `Y` is a compatible change, because this rule does not require -that the struct literals have to correspond, only that the defined types -denoted by `T` must correspond. (Remember that correspondence stops at type -names.) - -If one type is an alias that refers to the corresponding defined type, the -situation is the same: - -``` -// old -type T struct { X int } - -// new -type u struct { X, Y int } -type T = u -``` -Here, the only requirement is that old `T` corresponds to new `u`, not that the -struct types correspond. (We can't tell from this snippet that the old `T` and -the new `u` do correspond; that depends on whether `u` replaces `T` throughout -the API.) - -However, the following change is incompatible, because the names do not -denote corresponding types: - -``` -// old -type T = struct { X int } - -// new -type T = struct { X, Y int } -``` -### Type Literal Compatibility - -Only five kinds of types can differ compatibly: defined types, structs, -interfaces, channels and numeric types. We only consider the compatibility of -the last four when they are the underlying type of a defined type. See -"Compatibility, Types and Names" for a rationale. - -We justify the compatibility rules by enumerating all the ways a type -can be used, and by showing that the allowed changes cannot break any code that -uses values of the type in those ways. - -Values of all types can be used in assignments (including argument passing and -function return), but we do not require that old and new types are assignment -compatible. That is because we assume that the old and new packages are never -used together: any given binary will link in either the old package or the new. -So in describing how a type can be used in the sections below, we omit -assignment. - -Any type can also be used in a type assertion or conversion. The changes we allow -below may affect the run-time behavior of these operations, but they cannot affect -whether they compile. The only such breaking change would be to change -the type `T` in an assertion `x.T` so that it no longer implements the interface -type of `x`; but the rules for interfaces below disallow that. - -> A new type is compatible with an old one if and only if they correspond, or -> one of the cases below applies. - -#### Defined Types - -Other than assignment, the only ways to use a defined type are to access its -methods, or to make use of the properties of its underlying type. Rule 2 below -covers the latter, and rules 3 and 4 cover the former. - -> A new defined type is compatible with an old one if and only if all of the -> following hold: ->1. They correspond. ->2. Their underlying types are compatible. ->3. The new exported value method set is a superset of the old. ->4. The new exported pointer method set is a superset of the old. - -An exported method set is a method set with all unexported methods removed. -When comparing methods of a method set, we require identical names and -corresponding signatures. - -Removing an exported method is clearly a breaking change. But removing an -unexported one (or changing its signature) can be breaking as well, if it -results in the type no longer implementing an interface. See "Whole-Package -Compatibility," below. - -#### Channels - -> A new channel type is compatible with an old one if -> 1. The element types correspond, and -> 2. Either the directions are the same, or the new type has no direction. - -Other than assignment, the only ways to use values of a channel type are to send -and receive on them, to close them, and to use them as map keys. Changes to a -channel type cannot cause code that closes a channel or uses it as a map key to -fail to compile, so we need not consider those operations. - -Rule 1 ensures that any operations on the values sent or received will compile. -Rule 2 captures the fact that any program that compiles with a directed channel -must use either only sends, or only receives, so allowing the other operation -by removing the channel direction cannot break any code. - - -#### Interfaces - -> A new interface is compatible with an old one if and only if: -> 1. The old interface does not have an unexported method, and it corresponds -> to the new interfaces (i.e. they have the same method set), or -> 2. The old interface has an unexported method and the new exported method set is a -> superset of the old. - -Other than assignment, the only ways to use an interface are to implement it, -embed it, or call one of its methods. (Interface values can also be used as map -keys, but that cannot cause a compile-time error.) - -Certainly, removing an exported method from an interface could break a client -call, so neither rule allows it. - -Rule 1 also disallows adding a method to an interface without an existing unexported -method. Such an interface can be implemented in client code. If adding a method -were allowed, a type that implements the old interface could fail to implement -the new one: - -``` -type I interface { M1() } // old -type I interface { M1(); M2() } // new - -// client -type t struct{} -func (t) M1() {} -var i pkg.I = t{} // fails with new, because t lacks M2 -``` - -Rule 2 is based on the observation that if an interface has an unexported -method, the only way a client can implement it is to embed it. -Adding a method is compatible in this case, because the embedding struct will -continue to implement the interface. Adding a method also cannot break any call -sites, since no program that compiles could have any such call sites. - -#### Structs - -> A new struct is compatible with an old one if all of the following hold: -> 1. The new set of top-level exported fields is a superset of the old. -> 2. The new set of _selectable_ exported fields is a superset of the old. -> 3. If the old struct is comparable, so is the new one. - -The set of selectable exported fields is the set of exported fields `F` -such that `x.F` is a valid selector expression for a value `x` of the struct -type. `F` may be at the top level of the struct, or it may be a field of an -embedded struct. - -Two fields are the same if they have the same name and corresponding types. - -Other than assignment, there are only four ways to use a struct: write a struct -literal, select a field, use a value of the struct as a map key, or compare two -values for equality. The first clause ensures that struct literals compile; the -second, that selections compile; and the third, that equality expressions and -map index expressions compile. - -#### Numeric Types - -> A new numeric type is compatible with an old one if and only if they are -> both unsigned integers, both signed integers, both floats or both complex -> types, and the new one is at least as large as the old on both 32-bit and -> 64-bit architectures. - -Other than in assignments, numeric types appear in arithmetic and comparison -expressions. Since all arithmetic operations but shifts (see below) require that -operand types be identical, and by assumption the old and new types underly -defined types (see "Compatibility, Types and Names," below), there is no way for -client code to write an arithmetic expression that compiles with operands of the -old type but not the new. - -Numeric types can also appear in type switches and type assertions. Again, since -the old and new types underly defined types, type switches and type assertions -that compiled using the old defined type will continue to compile with the new -defined type. - -Going from an unsigned to a signed integer type is an incompatible change for -the sole reason that only an unsigned type can appear as the right operand of a -shift. If this rule is relaxed, then changes from an unsigned type to a larger -signed type would be compatible. See [this -issue](https://github.com/golang/go/issues/19113). - -Only integer types can be used in bitwise and shift operations, and for indexing -slices and arrays. That is why switching from an integer to a floating-point -type--even one that can represent all values of the integer type--is an -incompatible change. - - -Conversions from floating-point to complex types or vice versa are not permitted -(the predeclared functions real, imag, and complex must be used instead). To -prevent valid floating-point or complex conversions from becoming invalid, -changing a floating-point type to a complex type or vice versa is considered an -incompatible change. - -Although conversions between any two integer types are valid, assigning a -constant value to a variable of integer type that is too small to represent the -constant is not permitted. That is why the only compatible changes are to -a new type whose values are a superset of the old. The requirement that the new -set of values must include the old on both 32-bit and 64-bit machines allows -conversions from `int32` to `int` and from `int` to `int64`, but not the other -direction; and similarly for `uint`. - -Changing a type to or from `uintptr` is considered an incompatible change. Since -its size is not specified, there is no way to know whether the new type's values -are a superset of the old type's. - -## Whole-Package Compatibility - -Some changes that are compatible for a single type are not compatible when the -package is considered as a whole. For example, if you remove an unexported -method on a defined type, it may no longer implement an interface of the -package. This can break client code: - -``` -// old -type T int -func (T) m() {} -type I interface { m() } - -// new -type T int // no method m anymore - -// client -var i pkg.I = pkg.T{} // fails with new because T lacks m -``` - -Similarly, adding a method to an interface can cause defined types -in the package to stop implementing it. - -The second clause in the definition for package compatibility handles these -cases. To repeat: -> 2. For every exposed type that implements an exposed interface in the old package, -> its corresponding type should implement the corresponding interface in the new package. -Recall that a type is exposed if it is part of the package's API, even if it is -unexported. - -Other incompatibilities that involve more than one type in the package can arise -whenever two types with identical underlying types exist in the old or new -package. Here, a change "splits" an identical underlying type into two, breaking -conversions: - -``` -// old -type B struct { X int } -type C struct { X int } - -// new -type B struct { X int } -type C struct { X, Y int } - -// client -var b B -_ = C(b) // fails with new: cannot convert B to C -``` -Finally, changes that are compatible for the package in which they occur can -break downstream packages. That can happen even if they involve unexported -methods, thanks to embedding. - -The definitions given here don't account for these sorts of problems. - - -## Compatibility, Types and Names - -The above definitions state that the only types that can differ compatibly are -defined types and the types that underly them. Changes to other type literals -are considered incompatible. For instance, it is considered an incompatible -change to add a field to the struct in this variable declaration: - -``` -var V struct { X int } -``` -or this alias definition: -``` -type T = struct { X int } -``` - -We make this choice to keep the definition of compatibility (relatively) simple. -A more precise definition could, for instance, distinguish between - -``` -func F(struct { X int }) -``` -where any changes to the struct are incompatible, and - -``` -func F(struct { X, u int }) -``` -where adding a field is compatible (since clients cannot write the signature, -and thus cannot assign `F` to a variable of the signature type). The definition -should then also allow other function signature changes that only require -call-site compatibility, like - -``` -func F(struct { X, u int }, ...int) -``` -The result would be a much more complex definition with little benefit, since -the examples in this section rarely arise in practice. diff --git a/vendor/golang.org/x/exp/apidiff/apidiff.go b/vendor/golang.org/x/exp/apidiff/apidiff.go deleted file mode 100644 index 76669d8b05..0000000000 --- a/vendor/golang.org/x/exp/apidiff/apidiff.go +++ /dev/null @@ -1,220 +0,0 @@ -// TODO: test swap corresponding types (e.g. u1 <-> u2 and u2 <-> u1) -// TODO: test exported alias refers to something in another package -- does correspondence work then? -// TODO: CODE COVERAGE -// TODO: note that we may miss correspondences because we bail early when we compare a signature (e.g. when lengths differ; we could do up to the shorter) -// TODO: if you add an unexported method to an exposed interface, you have to check that -// every exposed type that previously implemented the interface still does.

In the simplest case, it may consist of a single file +// such as $GOROOT/src/net/http/triv.go. +// +// EXTERNAL TEST packages are those comprised of a set of *_test.go +// files all with the same 'package foo_test' declaration, all in the +// same directory. (go/build.Package calls these files XTestFiles.) +// +// An IMPORTABLE package is one that can be referred to by some import +// spec. Every importable package is uniquely identified by its +// PACKAGE PATH or just PATH, a string such as "fmt", "encoding/json", +// or "cmd/vendor/golang.org/x/arch/x86/x86asm". A package path +// typically denotes a subdirectory of the workspace. +// +// An import declaration uses an IMPORT PATH to refer to a package. +// Most import declarations use the package path as the import path. +// +// Due to VENDORING (https://golang.org/s/go15vendor), the +// interpretation of an import path may depend on the directory in which +// it appears. To resolve an import path to a package path, go/build +// must search the enclosing directories for a subdirectory named +// "vendor". +// +// ad hoc packages and external test packages are NON-IMPORTABLE. The +// path of an ad hoc package is inferred from the package +// declarations of its files and is therefore not a unique package key. +// For example, Config.CreatePkgs may specify two initial ad hoc +// packages, both with path "main". +// +// An AUGMENTED package is an importable package P plus all the +// *_test.go files with same 'package foo' declaration as P. +// (go/build.Package calls these files TestFiles.) +// +// The INITIAL packages are those specified in the configuration. A +// DEPENDENCY is a package loaded to satisfy an import in an initial +// package or another dependency. +// +package loader + +// IMPLEMENTATION NOTES +// +// 'go test', in-package test files, and import cycles +// --------------------------------------------------- +// +// An external test package may depend upon members of the augmented +// package that are not in the unaugmented package, such as functions +// that expose internals. (See bufio/export_test.go for an example.) +// So, the loader must ensure that for each external test package +// it loads, it also augments the corresponding non-test package. +// +// The import graph over n unaugmented packages must be acyclic; the +// import graph over n-1 unaugmented packages plus one augmented +// package must also be acyclic. ('go test' relies on this.) But the +// import graph over n augmented packages may contain cycles. +// +// First, all the (unaugmented) non-test packages and their +// dependencies are imported in the usual way; the loader reports an +// error if it detects an import cycle. +// +// Then, each package P for which testing is desired is augmented by +// the list P' of its in-package test files, by calling +// (*types.Checker).Files. This arrangement ensures that P' may +// reference definitions within P, but P may not reference definitions +// within P'. Furthermore, P' may import any other package, including +// ones that depend upon P, without an import cycle error. +// +// Consider two packages A and B, both of which have lists of +// in-package test files we'll call A' and B', and which have the +// following import graph edges: +// B imports A +// B' imports A +// A' imports B +// This last edge would be expected to create an error were it not +// for the special type-checking discipline above. +// Cycles of size greater than two are possible. For example: +// compress/bzip2/bzip2_test.go (package bzip2) imports "io/ioutil" +// io/ioutil/tempfile_test.go (package ioutil) imports "regexp" +// regexp/exec_test.go (package regexp) imports "compress/bzip2" +// +// +// Concurrency +// ----------- +// +// Let us define the import dependency graph as follows. Each node is a +// list of files passed to (Checker).Files at once. Many of these lists +// are the production code of an importable Go package, so those nodes +// are labelled by the package's path. The remaining nodes are +// ad hoc packages and lists of in-package *_test.go files that augment +// an importable package; those nodes have no label. +// +// The edges of the graph represent import statements appearing within a +// file. An edge connects a node (a list of files) to the node it +// imports, which is importable and thus always labelled. +// +// Loading is controlled by this dependency graph. +// +// To reduce I/O latency, we start loading a package's dependencies +// asynchronously as soon as we've parsed its files and enumerated its +// imports (scanImports). This performs a preorder traversal of the +// import dependency graph. +// +// To exploit hardware parallelism, we type-check unrelated packages in +// parallel, where "unrelated" means not ordered by the partial order of +// the import dependency graph. +// +// We use a concurrency-safe non-blocking cache (importer.imported) to +// record the results of type-checking, whether success or failure. An +// entry is created in this cache by startLoad the first time the +// package is imported. The first goroutine to request an entry becomes +// responsible for completing the task and broadcasting completion to +// subsequent requestors, which block until then. +// +// Type checking occurs in (parallel) postorder: we cannot type-check a +// set of files until we have loaded and type-checked all of their +// immediate dependencies (and thus all of their transitive +// dependencies). If the input were guaranteed free of import cycles, +// this would be trivial: we could simply wait for completion of the +// dependencies and then invoke the typechecker. +// +// But as we saw in the 'go test' section above, some cycles in the +// import graph over packages are actually legal, so long as the +// cycle-forming edge originates in the in-package test files that +// augment the package. This explains why the nodes of the import +// dependency graph are not packages, but lists of files: the unlabelled +// nodes avoid the cycles. Consider packages A and B where B imports A +// and A's in-package tests AT import B. The naively constructed import +// graph over packages would contain a cycle (A+AT) --> B --> (A+AT) but +// the graph over lists of files is AT --> B --> A, where AT is an +// unlabelled node. +// +// Awaiting completion of the dependencies in a cyclic graph would +// deadlock, so we must materialize the import dependency graph (as +// importer.graph) and check whether each import edge forms a cycle. If +// x imports y, and the graph already contains a path from y to x, then +// there is an import cycle, in which case the processing of x must not +// wait for the completion of processing of y. +// +// When the type-checker makes a callback (doImport) to the loader for a +// given import edge, there are two possible cases. In the normal case, +// the dependency has already been completely type-checked; doImport +// does a cache lookup and returns it. In the cyclic case, the entry in +// the cache is still necessarily incomplete, indicating a cycle. We +// perform the cycle check again to obtain the error message, and return +// the error. +// +// The result of using concurrency is about a 2.5x speedup for stdlib_test. diff --git a/vendor/golang.org/x/tools/go/loader/loader.go b/vendor/golang.org/x/tools/go/loader/loader.go new file mode 100644 index 0000000000..bc12ca33d1 --- /dev/null +++ b/vendor/golang.org/x/tools/go/loader/loader.go @@ -0,0 +1,1086 @@ +// Copyright 2013 The Go Authors.

x != nil { + for _, v := range x { + println(v, x) + } + } + +The corresponding AST expressed as an idiomatic pattern would look as follows: + + (IfStmt + (AssignStmt (Ident "x") ":=" (CallExpr (Ident "fn") [])) + (BinaryExpr (Ident "x") "!=" (Ident "nil")) + (RangeStmt + (Ident "_") (Ident "v") ":=" (Ident "x") + (CallExpr (Ident "println") [(Ident "v") (Ident "x")])) + nil) + +Two things are worth noting about this representation. +First, the [el1 el2 ...] syntax is a short-hand for creating lists. +It is a short-hand for el1:el2:[], which itself is a short-hand for (List el1 (List el2 (List nil nil)). +Second, note the absence of a lot of lists in places that normally accept lists. +For example, assignment assigns a number of right-hands to a number of left-hands, yet our AssignStmt is lacking any form of list. +This is due to the fact that a single node can match a list of exactly one element. +Thus, the two following forms have identical matching behavior: + + (AssignStmt (Ident "x") ":=" (CallExpr (Ident "fn") [])) + (AssignStmt [(Ident "x")] ":=" [(CallExpr (Ident "fn") [])]) + +This section serves as an overview of the language's syntax. +More in-depth explanations of the matching behavior as well as an exhaustive list of node types follows in the coming sections. + +Pattern matching + +TODO write about pattern matching + +- inspired by haskell syntax, but much, much simpler and naive + +Node types + +The language contains two kinds of nodes: those that map to nodes in the AST, and those that implement additional logic. + +Nodes that map directly to AST nodes are named identically to the types in the go/ast package. +What follows is an exhaustive list of these nodes: + + (ArrayType len elt) + (AssignStmt lhs tok rhs) + (BasicLit kind value) + (BinaryExpr x op y) + (BranchStmt tok label) + (CallExpr fun args) + (CaseClause list body) + (ChanType dir value) + (CommClause comm body) + (CompositeLit type elts) + (DeferStmt call) + (Ellipsis elt) + (EmptyStmt) + (Field names type tag) + (ForStmt init cond post body) + (FuncDecl recv name type body) + (FuncLit type body) + (FuncType params results) + (GenDecl specs) + (GoStmt call) + (Ident name) + (IfStmt init cond body else) + (ImportSpec name path) + (IncDecStmt x tok) + (IndexExpr x index) + (InterfaceType methods) + (KeyValueExpr key value) + (MapType key value) + (RangeStmt key value tok x body) + (ReturnStmt results) + (SelectStmt body) + (SelectorExpr x sel) + (SendStmt chan value) + (SliceExpr x low high max) + (StarExpr x) + (StructType fields) + (SwitchStmt init tag body) + (TypeAssertExpr) + (TypeSpec name type) + (TypeSwitchStmt init assign body) + (UnaryExpr op x) + (ValueSpec names type values) + +Additionally, there are the String, Token and nil atoms. +Strings are double-quoted string literals, as in (Ident "someName"). +Tokens are also represented as double-quoted string literals, but are converted to token.Token values in contexts that require tokens, +such as in (BinaryExpr x "<" y), where "<" is transparently converted to token.LSS during matching. +The keyword 'nil' denotes the nil value, which represents the absence of any value. + +We also defines the (List head tail) node, which is used to represent sequences of elements as a singly linked list. +The head is a single element, and the tail is the remainder of the list. +For example, + + (List "foo" (List "bar" (List "baz" (List nil nil)))) + +represents a list of three elements, "foo", "bar" and "baz". There is dedicated syntax for writing lists, which looks as follows: + + ["foo" "bar" "baz"] + +This syntax is itself syntactic sugar for the following form: + + "foo":"bar":"baz":[] + +This form is of particular interest for pattern matching, as it allows matching on the head and tail. For example, + + "foo":"bar":_ + +would match any list with at least two elements, where the first two elements are "foo" and "bar". This is equivalent to writing + + (List "foo" (List "bar" _)) + +Note that it is not possible to match from the end of the list. +That is, there is no way to express a query such as "a list of any length where the last element is foo". + +Note that unlike in LISP, nil and empty lists are distinct from one another. +In patterns, with respect to lists, nil is akin to Go's untyped nil. +It will match a nil ast.Node, but it will not match a nil []ast.Expr. Nil will, however, match pointers to named types such as *ast.Ident. +Similarly, lists are akin to Go's +slices. An empty list will match both a nil and an empty []ast.Expr, but it will not match a nil ast.Node. + +Due to the difference between nil and empty lists, an empty list is represented as (List nil nil), i.e. a list with no head or tail. +Similarly, a list of one element is represented as (List el (List nil nil)). Unlike in LISP, it cannot be represented by (List el nil). + +Finally, there are nodes that implement special logic or matching behavior. + +(Any) matches any value. The underscore (_) maps to this node, making the following two forms equivalent: + + (Ident _) + (Ident (Any)) + +(Builtin name) matches a built-in identifier or function by name. +This is a type-aware variant of (Ident name). +Instead of only comparing the name, it resolves the object behind the name and makes sure it's a pre-declared identifier. + +For example, in the following piece of code + + func fn() { + println(true) + true := false + println(true) + } + +the pattern + + (Builtin "true") + +will match exactly once, on the first use of 'true' in the function. +Subsequent occurrences of 'true' no longer refer to the pre-declared identifier. + +(Object name) matches an identifier by name, but yields the +types.Object it refers to. + +(Function name) matches ast.Idents and ast.SelectorExprs that refer to a function with a given fully qualified name. +For example, "net/url.PathEscape" matches the PathEscape function in the net/url package, +and "(net/url.EscapeError).Error" refers to the Error method on the net/url.EscapeError type, +either on an instance of the type, or on the type itself. + +For example, the following patterns match the following lines of code: + + (CallExpr (Function "fmt.Println") _) // pattern 1 + (CallExpr (Function "(net/url.EscapeError).Error") _) // pattern 2 + + fmt.Println("hello, world") // matches pattern 1 + var x url.EscapeError + x.Error() // matches pattern 2 + (url.EscapeError).Error(x) // also matches pattern 2 + +(Binding name node) creates or uses a binding. +Bindings work like variable assignments, allowing referring to already matched nodes. +As an example, bindings are necessary to match self-assignment of the form "x = x", +since we need to express that the right-hand side is identical to the left-hand side. + +If a binding's node is not nil, the matcher will attempt to match a node according to the pattern. +If a binding's node is nil, the binding will either recall an existing value, or match the Any node. +It is an error to provide a non-nil node to a binding that has already been bound. + +Referring back to the earlier example, the following pattern will match self-assignment of idents: + + (AssignStmt (Binding "lhs" (Ident _)) "=" (Binding "lhs" nil)) + +Because bindings are a crucial component of pattern matching, there is special syntax for creating and recalling bindings. +Lower-case names refer to bindings. If standing on its own, the name "foo" will be equivalent to (Binding "foo" nil). +If a name is followed by an at-sign (@) then it will create a binding for the node that follows. +Together, this allows us to rewrite the earlier example as follows: + + (AssignStmt lhs@(Ident _) "=" lhs) + +(Or nodes...) is a variadic node that tries matching each node until one succeeds. For example, the following pattern matches all idents of name "foo" or "bar": + + (Ident (Or "foo" "bar")) + +We could also have written + + (Or (Ident "foo") (Ident "bar")) + +and achieved the same result. We can also mix different kinds of nodes: + + (Or (Ident "foo") (CallExpr (Ident "bar") _)) + +When using bindings inside of nodes used inside Or, all or none of the bindings will be bound. +That is, partially matched nodes that ultimately failed to match will not produce any bindings observable outside of the matching attempt. +We can thus write + + (Or (Ident name) (CallExpr name)) + +and 'name' will either be a String if the first option matched, or an Ident or SelectorExpr if the second option matched. + +(Not node) + +The Not node negates a match. For example, (Not (Ident _)) will match all nodes that aren't identifiers. + +ChanDir(0) + +Automatic unnesting of AST nodes + +The Go AST has several types of nodes that wrap other nodes. +To simplify matching, we automatically unwrap some of these nodes. + +These nodes are ExprStmt (for using expressions in a statement context), +ParenExpr (for parenthesized expressions), +DeclStmt (for declarations in a statement context), +and LabeledStmt (for labeled statements). + +Thus, the query + + (FuncLit _ [(CallExpr _ _)] + +will match a function literal containing a single function call, +even though in the actual Go AST, the CallExpr is nested inside an ExprStmt, +as function bodies are made up of sequences of statements. + +On the flip-side, there is no way to specifically match these wrapper nodes. +For example, there is no way of searching for unnecessary parentheses, like in the following piece of Go code: + + ((x)) += 2 + +*/ +package pattern diff --git a/vendor/honnef.co/go/tools/pattern/fuzz.go b/vendor/honnef.co/go/tools/pattern/fuzz.go new file mode 100644 index 0000000000..52e7df9742 --- /dev/null +++ b/vendor/honnef.co/go/tools/pattern/fuzz.go @@ -0,0 +1,50 @@ +// +build gofuzz + +package pattern + +import ( + "go/ast" + goparser "go/parser" + "go/token" + "os" + "path/filepath" + "strings" +) + +var files []*ast.File + +func init() { + fset := token.NewFileSet() + filepath.Walk("/usr/lib/go/src", func(path string, info os.FileInfo, err error) error { + if err != nil { + // XXX error handling + panic(err) + } + if !strings.HasSuffix(path, ".go") { + return nil + } + f, err := goparser.ParseFile(fset, path, nil, 0) + if err != nil { + return nil + } + files = append(files, f) + return nil + }) +} + +func Fuzz(data []byte) int { + p := &Parser{} + pat, err := p.Parse(string(data)) + if err != nil { + if strings.Contains(err.Error(), "internal error") { + panic(err) + } + return 0 + } + _ = pat.Root.String() + + for _, f := range files { + Match(pat.Root, f) + } + return 1 +} diff --git a/vendor/honnef.co/go/tools/pattern/lexer.go b/vendor/honnef.co/go/tools/pattern/lexer.go new file mode 100644 index 0000000000..fb72e392bd --- /dev/null +++ b/vendor/honnef.co/go/tools/pattern/lexer.go @@ -0,0 +1,221 @@ +package pattern + +import ( + "fmt" + "go/token" + "unicode" + "unicode/utf8" +) + +type lexer struct { + f *token.File + + input string + start int + pos int + width int + items chan item +} + +type itemType int + +const eof = -1 + +const ( + itemError itemType = iota + itemLeftParen + itemRightParen + itemLeftBracket + itemRightBracket + itemTypeName + itemVariable + itemAt + itemColon + itemBlank + itemString + itemEOF +) + +func (typ itemType) String() string { + switch typ { + case itemError: + return "ERROR" + case itemLeftParen: + return "(" + case itemRightParen: + return ")" + case itemLeftBracket: + return "[" + case itemRightBracket: + return "]" + case itemTypeName: + return "TYPE" + case itemVariable: + return "VAR" + case itemAt: + return "@" + case itemColon: + return ":" + case itemBlank: + return "_" + case itemString: + return "STRING" + case itemEOF: + return "EOF" + default: + return fmt.Sprintf("itemType(%d)", typ) + } +} + +type item struct { + typ itemType + val string + pos int +} + +type stateFn func(*lexer) stateFn + +func (l *lexer) run() { + for state := lexStart;
