The a variable will be true. - a := c.Check(v) -``` - -## Basic Comparisons - -There are two elements to the comparisons. First, a comparison string is a list -of comma separated and comparisons. These are then separated by || separated or -comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a -comparison that's greater than or equal to 1.2 and less than 3.0.0 or is -greater than or equal to 4.2.3. - -The basic comparisons are: - -* `=`: equal (aliased to no operator) -* `!=`: not equal -* `>`: greater than -* `<`: less than -* `>=`: greater than or equal to -* `<=`: less than or equal to - -_Note, according to the Semantic Version specification pre-releases may not be -API compliant with their release counterpart. It says,_ - -> _A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version._ - -_SemVer comparisons without a pre-release value will skip pre-release versions. -For example, `>1.2.3` will skip pre-releases when looking at a list of values -while `>1.2.3-alpha.1` will evaluate pre-releases._ - -## Hyphen Range Comparisons - -There are multiple methods to handle ranges and the first is hyphens ranges. -These look like: - -* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` -* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5` - -## Wildcards In Comparisons - -The `x`, `X`, and `*` characters can be used as a wildcard character. This works -for all comparison operators. When used on the `=` operator it falls -back to the pack level comparison (see tilde below). For example, - -* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` -* `>= 1.2.x` is equivalent to `>= 1.2.0` -* `<= 2.x` is equivalent to `<= 3` -* `*` is equivalent to `>= 0.0.0` - -## Tilde Range Comparisons (Patch) - -The tilde (`~`) comparison operator is for patch level ranges when a minor -version is specified and major level changes when the minor number is missing. -For example, - -* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` -* `~1` is equivalent to `>= 1, < 2` -* `~2.3` is equivalent to `>= 2.3, < 2.4` -* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` -* `~1.x` is equivalent to `>= 1, < 2` - -## Caret Range Comparisons (Major) - -The caret (`^`) comparison operator is for major level changes. This is useful -when comparisons of API versions as a major change is API breaking. For example, - -* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` -* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` -* `^2.3` is equivalent to `>= 2.3, < 3` -* `^2.x` is equivalent to `>= 2.0.0, < 3` - -# Validation - -In addition to testing a version against a constraint, a version can be validated -against a constraint. When validation fails a slice of errors containing why a -version didn't meet the constraint is returned. For example, - -```go - c, err := semver.NewConstraint("<= 1.2.3, >= 1.4") - if err != nil { - // Handle constraint not being parseable. - } - - v, _ := semver.NewVersion("1.3") - if err != nil { - // Handle version not being parseable. - } - - // Validate a version against a constraint. - a, msgs := c.Validate(v) - // a is false - for _, m := range msgs { - fmt.Println(m) - - // Loops over the errors which would read - // "1.3 is greater than 1.2.3" - // "1.3 is less than 1.4" - } -``` - -# Contribute - -If you find an issue or want to contribute please file an [issue](https://github.com/Masterminds/semver/issues) -or [create a pull request](https://github.com/Masterminds/semver/pulls). diff --git a/vendor/github.com/Masterminds/semver/appveyor.yml b/vendor/github.com/Masterminds/semver/appveyor.yml deleted file mode 100644 index b2778df15a..0000000000 --- a/vendor/github.com/Masterminds/semver/appveyor.yml +++ /dev/null @@ -1,44 +0,0 @@ -version: build-{build}.{branch} - -clone_folder: C:\gopath\src\github.com\Masterminds\semver -shallow_clone: true - -environment: - GOPATH: C:\gopath - -platform: - - x64 - -install: - - go version - - go env - - go get -u gopkg.in/alecthomas/gometalinter.v1 - - set PATH=%PATH%;%GOPATH%\bin - - gometalinter.v1.exe --install - -build_script: - - go install -v ./... - -test_script: - - "gometalinter.v1 \ - --disable-all \ - --enable deadcode \ - --severity deadcode:error \ - --enable gofmt \ - --enable gosimple \ - --enable ineffassign \ - --enable misspell \ - --enable vet \ - --tests \ - --vendor \ - --deadline 60s \ - ./... || exit_code=1" - - "gometalinter.v1 \ - --disable-all \ - --enable golint \ - --vendor \ - --deadline 60s \ - ./... || :" - - go test -v - -deploy: off diff --git a/vendor/github.com/Masterminds/semver/constraints.go b/vendor/github.com/Masterminds/semver/constraints.go deleted file mode 100644 index a41a6a7a4a..0000000000 --- a/vendor/github.com/Masterminds/semver/constraints.go +++ /dev/null @@ -1,426 +0,0 @@ -package semver - -import ( - "errors" - "fmt" - "regexp" - "strings" -) - -// Constraints is one or more constraint that a semantic version can be -// checked against. -type Constraints struct { - constraints [][]*constraint -} - -// NewConstraint returns a Constraints instance that a Version instance can -// be checked against.

This is the + previous stable and is still maintained for bug fixes. The development, to fix + bugs, occurs on the release-1 branch. You can read the documentation [here](https://github.com/Masterminds/semver/blob/release-1/README.md). + +## Parsing Semantic Versions + +There are two functions that can parse semantic versions. The `StrictNewVersion` +function only parses valid version 2 semantic versions as outlined in the +specification. The `NewVersion` function attempts to coerce a version into a +semantic version and parse it. For example, if there is a leading v or a version +listed without all 3 parts (e.g. `v1.2`) it will attempt to coerce it into a valid +semantic version (e.g., 1.2.0). In both cases a `Version` object is returned +that can be sorted, compared, and used in constraints. + +When parsing a version an error is returned if there is an issue parsing the +version. For example, + + v, err := semver.NewVersion("1.2.3-beta.1+build345") + +The version object has methods to get the parts of the version, compare it to +other versions, convert the version back into a string, and get the original +string. Getting the original string is useful if the semantic version was coerced +into a valid form. + +## Sorting Semantic Versions + +A set of versions can be sorted using the `sort` package from the standard library. +For example, + +```go +raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",} +vs := make([]*semver.Version, len(raw)) +for i, r := range raw { + v, err := semver.NewVersion(r) + if err != nil { + t.Errorf("Error parsing version: %s", err) + } + + vs[i] = v +} + +sort.Sort(semver.Collection(vs)) +``` + +## Checking Version Constraints + +There are two methods for comparing versions. One uses comparison methods on +`Version` instances and the other uses `Constraints`. There are some important +differences to notes between these two methods of comparison. + +1. When two versions are compared using functions such as `Compare`, `LessThan`, + and others it will follow the specification and always include prereleases + within the comparison. It will provide an answer that is valid with the + comparison section of the spec at https://semver.org/#spec-item-11 +2. When constraint checking is used for checks or validation it will follow a + different set of rules that are common for ranges with tools like npm/js + and Rust/Cargo. This includes considering prereleases to be invalid if the + ranges does not include one. If you want to have it include pre-releases a + simple solution is to include `-0` in your range. +3. Constraint ranges can have some complex rules including the shorthand use of + ~ and ^. For more details on those see the options below. + +There are differences between the two methods or checking versions because the +comparison methods on `Version` follow the specification while comparison ranges +are not part of the specification. Different packages and tools have taken it +upon themselves to come up with range rules. This has resulted in differences. +For example, npm/js and Cargo/Rust follow similar patterns while PHP has a +different pattern for ^. The comparison features in this package follow the +npm/js and Cargo/Rust lead because applications using it have followed similar +patters with their versions. + +Checking a version against version constraints is one of the most featureful +parts of the package. + +```go +c, err := semver.NewConstraint(">= 1.2.3") +if err != nil { + // Handle constraint not being parsable. +} + +v, err := semver.NewVersion("1.3") +if err != nil { + // Handle version not being parsable. +} +// Check if the version meets the constraints. The a variable will be true. +a := c.Check(v) +``` + +### Basic Comparisons + +There are two elements to the comparisons. First, a comparison string is a list +of space or comma separated AND comparisons. These are then separated by || (OR) +comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a +comparison that's greater than or equal to 1.2 and less than 3.0.0 or is +greater than or equal to 4.2.3. + +The basic comparisons are: + +* `=`: equal (aliased to no operator) +* `!=`: not equal +* `>`: greater than +* `<`: less than +* `>=`: greater than or equal to +* `<=`: less than or equal to + +### Working With Prerelease Versions + +Pre-releases, for those not familiar with them, are used for software releases +prior to stable or generally available releases. Examples of prereleases include +development, alpha, beta, and release candidate releases. A prerelease may be +a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the +order of precedence, prereleases come before their associated releases. In this +example `1.2.3-beta.1 < 1.2.3`. + +According to the Semantic Version specification prereleases may not be +API compliant with their release counterpart. It says, + +> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version. + +SemVer comparisons using constraints without a prerelease comparator will skip +prerelease versions. For example, `>=1.2.3` will skip prereleases when looking +at a list of releases while `>=1.2.3-0` will evaluate and find prereleases. + +The reason for the `0` as a pre-release version in the example comparison is +because pre-releases can only contain ASCII alphanumerics and hyphens (along with +`.` separators), per the spec. Sorting happens in ASCII sort order, again per the +spec. The lowest character is a `0` in ASCII sort order +(see an [ASCII Table](http://www.asciitable.com/)) + +Understanding ASCII sort ordering is important because A-Z comes before a-z. That +means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case +sensitivity doesn't apply here. This is due to ASCII sort ordering which is what +the spec specifies. + +### Hyphen Range Comparisons + +There are multiple methods to handle ranges and the first is hyphens ranges. +These look like: + +* `1.2 - 1.4.5` which is equivalent to `>= 1.2 <= 1.4.5` +* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5` + +### Wildcards In Comparisons + +The `x`, `X`, and `*` characters can be used as a wildcard character. This works +for all comparison operators. When used on the `=` operator it falls +back to the patch level comparison (see tilde below). For example, + +* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` +* `>= 1.2.x` is equivalent to `>= 1.2.0` +* `<= 2.x` is equivalent to `< 3` +* `*` is equivalent to `>= 0.0.0` + +### Tilde Range Comparisons (Patch) + +The tilde (`~`) comparison operator is for patch level ranges when a minor +version is specified and major level changes when the minor number is missing. +For example, + +* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` +* `~1` is equivalent to `>= 1, < 2` +* `~2.3` is equivalent to `>= 2.3, < 2.4` +* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` +* `~1.x` is equivalent to `>= 1, < 2` + +### Caret Range Comparisons (Major) + +The caret (`^`) comparison operator is for major level changes once a stable +(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts +as the API stability level. This is useful when comparisons of API versions as a +major change is API breaking. For example, + +* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` +* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` +* `^2.3` is equivalent to `>= 2.3, < 3` +* `^2.x` is equivalent to `>= 2.0.0, < 3` +* `^0.2.3` is equivalent to `>=0.2.3 <0.3.0` +* `^0.2` is equivalent to `>=0.2.0 <0.3.0` +* `^0.0.3` is equivalent to `>=0.0.3 <0.0.4` +* `^0.0` is equivalent to `>=0.0.0 <0.1.0` +* `^0` is equivalent to `>=0.0.0 <1.0.0` + +## Validation + +In addition to testing a version against a constraint, a version can be validated +against a constraint. When validation fails a slice of errors containing why a +version didn't meet the constraint is returned. For example, + +```go +c, err := semver.NewConstraint("<= 1.2.3, >= 1.4") +if err != nil { + // Handle constraint not being parseable. +} + +v, err := semver.NewVersion("1.3") +if err != nil { + // Handle version not being parseable. +} + +// Validate a version against a constraint. +a, msgs := c.Validate(v) +// a is false +for _, m := range msgs { + fmt.Println(m) + + // Loops over the errors which would read + // "1.3 is greater than 1.2.3" + // "1.3 is less than 1.4" +} +``` + +## Contribute + +If you find an issue or want to contribute please file an [issue](https://github.com/Masterminds/semver/issues) +or [create a pull request](https://github.com/Masterminds/semver/pulls). diff --git a/vendor/github.com/Masterminds/semver/collection.go b/vendor/github.com/Masterminds/semver/v3/collection.go similarity index 100% rename from vendor/github.com/Masterminds/semver/collection.go rename to vendor/github.com/Masterminds/semver/v3/collection.go diff --git a/vendor/github.com/Masterminds/semver/v3/constraints.go b/vendor/github.com/Masterminds/semver/v3/constraints.go new file mode 100644 index 0000000000..7420823675 --- /dev/null +++ b/vendor/github.com/Masterminds/semver/v3/constraints.go @@ -0,0 +1,571 @@ +package semver + +import ( + "bytes" + "errors" + "fmt" + "regexp" + "strings" +) + +// Constraints is one or more constraint that a semantic version can be +// checked against. +type Constraints struct { + constraints [][]*constraint +} + +// NewConstraint returns a Constraints instance that a Version instance can +// be checked against.

One uses comparison methods on +`Version` instances and the other is using Constraints. There are some important +differences to notes between these two methods of comparison. + +1. When two versions are compared using functions such as `Compare`, `LessThan`, + and others it will follow the specification and always include prereleases + within the comparison. It will provide an answer valid with the comparison + spec section at https://semver.org/#spec-item-11 +2. When constraint checking is used for checks or validation it will follow a + different set of rules that are common for ranges with tools like npm/js + and Rust/Cargo. This includes considering prereleases to be invalid if the + ranges does not include on. If you want to have it include pre-releases a + simple solution is to include `-0` in your range. +3. Constraint ranges can have some complex rules including the shorthard use of + ~ and ^. For more details on those see the options below. + +There are differences between the two methods or checking versions because the +comparison methods on `Version` follow the specification while comparison ranges +are not part of the specification. Different packages and tools have taken it +upon themselves to come up with range rules. This has resulted in differences. +For example, npm/js and Cargo/Rust follow similar patterns which PHP has a +different pattern for ^. The comparison features in this package follow the +npm/js and Cargo/Rust lead because applications using it have followed similar +patters with their versions. + +Checking a version against version constraints is one of the most featureful +parts of the package. + + c, err := semver.NewConstraint(">= 1.2.3") + if err != nil { + // Handle constraint not being parsable. + } + + v, err := semver.NewVersion("1.3") + if err != nil { + // Handle version not being parsable. + } + // Check if the version meets the constraints. The a variable will be true. + a := c.Check(v) + +Basic Comparisons + +There are two elements to the comparisons. First, a comparison string is a list +of comma or space separated AND comparisons. These are then separated by || (OR) +comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a +comparison that's greater than or equal to 1.2 and less than 3.0.0 or is +greater than or equal to 4.2.3. This can also be written as +`">= 1.2, < 3.0.0 || >= 4.2.3"` + +The basic comparisons are: + + * `=`: equal (aliased to no operator) + * `!=`: not equal + * `>`: greater than + * `<`: less than + * `>=`: greater than or equal to + * `<=`: less than or equal to + +Hyphen Range Comparisons + +There are multiple methods to handle ranges and the first is hyphens ranges. +These look like: + + * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` + * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5` + +Wildcards In Comparisons + +The `x`, `X`, and `*` characters can be used as a wildcard character. This works +for all comparison operators. When used on the `=` operator it falls +back to the tilde operation. For example, + + * `1.2.x` is equivalent to `>= 1.2.0 < 1.3.0` + * `>= 1.2.x` is equivalent to `>= 1.2.0` + * `<= 2.x` is equivalent to `<= 3` + * `*` is equivalent to `>= 0.0.0` + +Tilde Range Comparisons (Patch) + +The tilde (`~`) comparison operator is for patch level ranges when a minor +version is specified and major level changes when the minor number is missing. +For example, + + * `~1.2.3` is equivalent to `>= 1.2.3 < 1.3.0` + * `~1` is equivalent to `>= 1, < 2` + * `~2.3` is equivalent to `>= 2.3 < 2.4` + * `~1.2.x` is equivalent to `>= 1.2.0 < 1.3.0` + * `~1.x` is equivalent to `>= 1 < 2` + +Caret Range Comparisons (Major) + +The caret (`^`) comparison operator is for major level changes once a stable +(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts +as the API stability level. This is useful when comparisons of API versions as a +major change is API breaking. For example, + + * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` + * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` + * `^2.3` is equivalent to `>= 2.3, < 3` + * `^2.x` is equivalent to `>= 2.0.0, < 3` + * `^0.2.3` is equivalent to `>=0.2.3 <0.3.0` + * `^0.2` is equivalent to `>=0.2.0 <0.3.0` + * `^0.0.3` is equivalent to `>=0.0.3 <0.0.4` + * `^0.0` is equivalent to `>=0.0.0 <0.1.0` + * `^0` is equivalent to `>=0.0.0 <1.0.0` + +Validation + +In addition to testing a version against a constraint, a version can be validated +against a constraint. When validation fails a slice of errors containing why a +version didn't meet the constraint is returned. For example, + + c, err := semver.NewConstraint("<= 1.2.3, >= 1.4") + if err != nil { + // Handle constraint not being parseable. + } + + v, _ := semver.NewVersion("1.3") + if err != nil { + // Handle version not being parseable. + } + + // Validate a version against a constraint. + a, msgs := c.Validate(v) + // a is false + for _, m := range msgs { + fmt.Println(m) + + // Loops over the errors which would read + // "1.3 is greater than 1.2.3" + // "1.3 is less than 1.4" + } +*/ +package semver diff --git a/vendor/github.com/Masterminds/semver/v3/fuzz.go b/vendor/github.com/Masterminds/semver/v3/fuzz.go new file mode 100644 index 0000000000..a242ad7058 --- /dev/null +++ b/vendor/github.com/Masterminds/semver/v3/fuzz.go @@ -0,0 +1,22 @@ +// +build gofuzz + +package semver + +func Fuzz(data []byte) int { + d := string(data) + + // Test NewVersion + _, _ = NewVersion(d) + + // Test StrictNewVersion + _, _ = StrictNewVersion(d) + + // Test NewConstraint + _, _ = NewConstraint(d) + + // The return value should be 0 normally, 1 if the priority in future tests + // should be increased, and -1 if future tests should skip passing in that + // data.

Sprig is a library that provides more than 100 commonly +used template functions. + +It is inspired by the template functions found in +[Twig](http://twig.sensiolabs.org/documentation) and in various +JavaScript libraries, such as [underscore.js](http://underscorejs.org/). + +## IMPORTANT NOTES + +Sprig leverages [mergo](https://github.com/imdario/mergo) to handle merges. In +its v0.3.9 release there was a behavior change that impacts merging template +functions in sprig. It is currently recommended to use v0.3.8 of that package. +Using v0.3.9 will cause sprig tests to fail. The issue in mergo is tracked at +https://github.com/imdario/mergo/issues/139. + +## Package Versions + +There are two active major versions of the `sprig` package. + +* v3 is currently stable release series on the `master` branch. The Go API should + remain compatible with v2, the current stable version. Behavior change behind + some functions is the reason for the new major version. +* v2 is the previous stable release series. It has been more than three years since + the initial release of v2. You can read the documentation and see the code + on the [release-2](https://github.com/Masterminds/sprig/tree/release-2) branch. + Bug fixes to this major version will continue for some time. + +## Usage + +**Template developers**: Please use Sprig's [function documentation](http://masterminds.github.io/sprig/) for +detailed instructions and code snippets for the >100 template functions available. + +**Go developers**: If you'd like to include Sprig as a library in your program, +our API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig). + +For standard usage, read on. + +### Load the Sprig library + +To load the Sprig `FuncMap`: + +```go + +import ( + "github.com/Masterminds/sprig" + "html/template" +) + +// This example illustrates that the FuncMap *must* be set before the +// templates themselves are loaded. +tpl := template.Must( + template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html") +) + + +``` + +### Calling the functions inside of templates + +By convention, all functions are lowercase. This seems to follow the Go +idiom for template functions (as opposed to template methods, which are +TitleCase). For example, this: + +``` +{{ "hello!" | upper | repeat 5 }} +``` + +produces this: + +``` +HELLO!HELLO!HELLO!HELLO!HELLO! +``` + +## Principles Driving Our Function Selection + +We followed these principles to decide which functions to add and how to implement them: + +- Use template functions to build layout. The following + types of operations are within the domain of template functions: + - Formatting + - Layout + - Simple type conversions + - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic) +- Template functions should not return errors unless there is no way to print + a sensible value. For example, converting a string to an integer should not + produce an error if conversion fails. Instead, it should display a default + value. +- Simple math is necessary for grid layouts, pagers, and so on. Complex math + (anything other than arithmetic) should be done outside of templates. +- Template functions only deal with the data passed into them. They never retrieve + data from a source. +- Finally, do not override core Go template functions. diff --git a/vendor/github.com/Masterminds/sprig/crypto.go
