const AllAccessProject = "proj-foo"

AllAccessProject is the project name that can be used to get a full-access project (i.e. unauthenticated users have both R and W permissions).


This section is empty.


func TestSecret

	// Opts is the set of archival options that the Storage was instantiated with.
	Opts archive.Options
	// contains filtered or unexported fields

ArchivalStorage is a bound GSClient-backed Storage instance.

func (*ArchivalStorage) Close

func (st *ArchivalStorage) Close()

Close implements storage.Storage.

func (*ArchivalStorage) GetSignedURLs

GetSignedURLs implements coordinator.SigningStorage.

type BigTableStorage

type BigTableStorage struct {
	// Testing is the base in-memory BigTable instance that is backing this
	// Storage.
	// contains filtered or unexported fields

BigTableStorage is a bound BigTable-backed Storage instance.

func (*BigTableStorage) Close

func (st *BigTableStorage) Close()

Close implements storage.Storage.

func (*BigTableStorage) GetSignedURLs

type Environment

type Environment struct {
	// ServiceID is LogDog's service ID for tests.
	ServiceID string

	// Clock is the installed test clock instance.
	Clock testclock.TestClock

	// AuthState is the fake authentication state.
	AuthState authtest.FakeState

	// Services is the set of installed Coordinator services.
	Services Services

	// BigTable in-memory testing instance.
	BigTable bigtable.Testing
	// GSClient is the test GSClient instance installed (by default) into
	// Services.

	StorageCache StorageCache
	// contains filtered or unexported fields

Environment contains all of the testing facilities that are installed into the Context.

func Install

func Install(useRealIndex bool) (context.Context, *Environment)

Install creates a testing Context and installs common test facilities into it, returning the Environment to which they're bound.

If useRealIndex is true, this will attempt to load the 'index.yaml' file for logdog (but this is loaded from a relative path, so is only really good for the 'coordinator' package). Otherwise this will turn on datastore's automatic indexing functionality.

func (*Environment) JoinGroup

func (e *Environment) JoinGroup(g string)

JoinGroup adds the named group the to the list of groups for the current identity.

func (*Environment) LeaveAllGroups

func (e *Environment) LeaveAllGroups()

LeaveAllGroups clears all auth groups that the user is currently a member of.

func (*Environment) LogIn

func (e *Environment) LogIn()

LogIn installs an testing identity into the testing auth state.

func (*Environment) ModProjectConfig

func (e *Environment) ModProjectConfig(c context.Context, project string, fn func(*svcconfig.ProjectConfig))

ModProjectConfig loads the current configuration for the named project, invokes the callback with its contents, and writes the result back to config.

func (*Environment) ModServiceConfig

func (e *Environment) ModServiceConfig(c context.Context, fn func(*svcconfig.Config))

ModServiceConfig loads the current service configuration, invokes the callback with its contents, and writes the result back to config.

type GSClient

type GSClient map[gs.Path][]byte

func (c GSClient) Close() error

Close implements gs.Client.

func (GSClient) Delete

func (c GSClient) Delete(gs.Path) error

Delete implements gs.Client.

func (GSClient) Get

func (c GSClient) Get(path gs.Path) []byte

Get retrieves the data at the specific path.

func (GSClient) NewReader

func (c GSClient) NewReader(path gs.Path, offset int64, length int64) (io.ReadCloser, error)

NewReader implements gs.Client.

func (GSClient) NewWriter

func (c GSClient) NewWriter(gs.Path) (gs.Writer, error)

NewWriter implements gs.Client.

func (GSClient) Put

func (c GSClient) Put(path gs.Path, d []byte)

Put sets the data at a given path.

func (GSClient) Rename

func (c GSClient) Rename(gs.Path, gs.Path) error

Rename implements gs.Client.

type Services

type Services struct {
	// Storage returns an intermediate storage instance for use by this service.
	// The caller must close the returned instance if successful.
	// By default, this will return a *BigTableStorage instance bound to the
	// Environment's BigTable instance if the stream is not archived, and an
	// *ArchivalStorage instance bound to this Environment's GSClient instance
	// if the stream is archived.
	ST func(*coordinator.LogStreamState) (coordinator.SigningStorage, error)

Services is a testing stub for a coordinator.Services instance that allows the user to configure the various services that are returned.
