Overview

Package internal contains data used through x/pkgsite.

Index

Constants

const (
	// LatestVersion signifies the latest available version in requests to the
	// proxy client.
	LatestVersion = "latest"

	// MasterVersion signifies the version at master.
	MasterVersion = "master"

	// UnknownModulePath signifies that the module path for a given package
	// path is ambiguous or not known. This is because requests to the
	// frontend can come in the form of <import-path>[@<version>], and it is
	// not clear which part of the import-path is the module path.
	UnknownModulePath = "unknownModulePath"
)
const (
	ExperimentAutocomplete = "autocomplete"
	ExperimentSidenav      = "sidenav"
	ExperimentUnitPage     = "unit-page"
	ExperimentUseUnits     = "use-units"
)
const StringFieldMissing = "!MISSING"

StringFieldMissing is the value for string fields that are not present in a struct. We use it to distinguish a (possibly valid) empty string from a field that was never populated.

Variables

var Experiments = map[string]string{
	ExperimentAutocomplete: "Enable autocomplete with search.",
	ExperimentSidenav:      "Display documentation index on the left sidenav.",
	ExperimentUnitPage:     "Enable the redesigned details page.",
	ExperimentUseUnits:     "Read from paths, documentation, readmes, and package_imports tables.",
}

Experiments represents all of the active experiments in the codebase and a description of each experiment.

func SeriesPathForModule

func SeriesPathForModule(modulePath string) string

SeriesPathForModule returns the series path for the provided modulePath.

func Suffix

func Suffix(fullPath, basePath string) string

Suffix returns the suffix of the fullPath. It assumes that basePath is a prefix of fullPath. If fullPath and basePath are the same, the empty string is returned.

func V1Path

func V1Path(fullPath, modulePath string) string

V1Path returns the path for version 1 of the package whose import path is fullPath. If modulePath is the standard library, then V1Path returns fullPath.

	// Description provides a description of the experiment.
	Description string
}

Experiment holds data associated with an experimental feature for frontend or worker.

type FieldSet

type FieldSet int64

A FieldSet is a bit set of struct fields. It is used to avoid reading large struct fields from the data store. FieldSet is also the type of the individual bit values. (Think of them as singleton sets.)

MinimalFields (the zero value) is the empty set. AllFields is the set containing every field.

FieldSet bits are unique across the entire project, because some types are concatenations (via embedding) of others. For example, a LegacyVersionedPackage contains the fields of both a LegacyModuleInfo and a LegacyPackage, so we can't use the same bits for both LegacyModuleInfo's LegacyReadmeContents field and LegacyPackage's DocumentationHTML field.

const (
	WithReadme FieldSet = 1 << iota
	WithDocumentation
	WithImports
	WithLicenses
	WithSubdirectories
)

FieldSet bits for fields that can be conditionally read from the data store.

const AllFields FieldSet = -1

AllFields is the FieldSet that contains all fields.

const MinimalFields FieldSet = 0

MinimalFields is the empty FieldSet.

func (*ModuleInfo) SeriesPath

func (v *ModuleInfo) SeriesPath() string

SeriesPath returns the series path for the module.

A series is a group of modules that share the same base path and are assumed to be major-version variants.

The series path is the module path without the version. For most modules, this will be the module path for all module versions with major version 0 or 1. For gopkg.in modules, the series path does not correspond to any module version.

Examples: The module paths "a/b" and "a/b/v2" both have series path "a/b". The module paths "gopkg.in/yaml.v1" and "gopkg.in/yaml.v2" both have series path "gopkg.in/yaml".
