Constants ¶
const ConfigID = ControllerID
ConfigID is the identifier for the config type.
const ControllerID = "controllerbus/plugin/loader/shared-library/filesystem"
ControllerID is the ID of the controller.
Variables ¶
var Version = semver.MustParse("0.0.1")
Version is the version of the controller implementation.
Functions ¶
This section is empty.
Types ¶
type Config ¶
type Config struct {
// Dir is the directory to load from.
Dir string `protobuf:"bytes,1,opt,name=dir,proto3" json:"dir,omitempty"`
// Watch will watch the directory and hot-reload plugins.
Watch bool `protobuf:"varint,2,opt,name=watch,proto3" json:"watch,omitempty"`
// contains filtered or unexported fields
}
Config is configuration for the filesystem hot-plugin loader.
func (*Config) CloneMessageVT ¶ added in v0.23.6
func (m *Config) CloneMessageVT() protobuf_go_lite.CloneMessage
func (*Config) EqualMessageVT ¶ added in v0.23.6
func (*Config) EqualsConfig ¶
EqualsConfig checks equality between two configs.
func (*Config) GetConfigID ¶
GetConfigID returns the config identifier.
func (*Config) MarshalJSON ¶ added in v0.41.0
MarshalJSON marshals the Config to JSON.
func (*Config) MarshalProtoJSON ¶ added in v0.41.0
func (x *Config) MarshalProtoJSON(s *json.MarshalState)
MarshalProtoJSON marshals the Config message to JSON.
func (*Config) MarshalProtoText ¶ added in v0.42.0
func (*Config) MarshalToSizedBufferVT ¶ added in v0.10.0
func (*Config) MarshalToVT ¶ added in v0.10.0
func (*Config) ProtoMessage ¶
func (*Config) ProtoMessage()
func (*Config) UnmarshalJSON ¶ added in v0.41.0
UnmarshalJSON unmarshals the Config from JSON.
func (*Config) UnmarshalProtoJSON ¶ added in v0.41.0
func (x *Config) UnmarshalProtoJSON(s *json.UnmarshalState)
UnmarshalProtoJSON unmarshals the Config message from JSON.
func (*Config) UnmarshalVT ¶ added in v0.10.0
type Controller ¶
type Controller struct {
// contains filtered or unexported fields
}
Controller is the hot plugin filesystem loading controller.
NOTE: Go plugins cannot be unloaded (Go 1.16). This is only a prototype.
func NewController ¶
NewController constructs a new controller.
func (*Controller) Close ¶
func (c *Controller) Close() error
Close releases any resources used by the controller. Error indicates any issue encountered releasing.
func (*Controller) Execute ¶
func (c *Controller) Execute(ctx context.Context) error
Execute executes the controller goroutine. Returning nil ends execution. Returning an error triggers a retry with backoff.
func (*Controller) GetControllerInfo ¶
func (c *Controller) GetControllerInfo() *controller.Info
GetControllerInfo returns information about the controller.
func (*Controller) HandleDirective ¶
func (c *Controller) HandleDirective( ctx context.Context, di directive.Instance, ) ([]directive.Resolver, error)
HandleDirective asks if the handler can resolve the directive. If it can, it returns a resolver. If not, returns nil. Any unexpected errors are returned for logging. It is safe to add a reference to the directive during this call.
type Factory ¶
type Factory struct {
// contains filtered or unexported fields
}
Factory constructs a hot loading from filesystem controller.
func NewFactory ¶
NewFactory builds a websocket transport factory.
func (*Factory) Construct ¶
func (t *Factory) Construct( ctx context.Context, conf config.Config, opts controller.ConstructOpts, ) (controller.Controller, error)
Construct constructs the associated controller given configuration.
func (*Factory) ConstructConfig ¶
ConstructConfig constructs an instance of the controller configuration.
func (*Factory) GetConfigID ¶
GetConfigID returns the configuration ID for the controller.
func (*Factory) GetControllerID ¶
GetControllerID returns the unique ID for the controller.
func (*Factory) GetVersion ¶
func (t *Factory) GetVersion() semver.Version
GetVersion returns the version of this controller.
type Watcher ¶
type Watcher struct {
// contains filtered or unexported fields
}
Watcher watches a filesystem path to load and reload plugins.
func NewWatcher ¶
NewWatcher builds a new filesystem watcher.
func (*Watcher) LoadPlugin ¶
LoadPlugin loads a plugin from a path.
If the path was already loaded, no-op.
func (*Watcher) SyncPlugins ¶
SyncPlugins synchronizes the loaded plugins with all in a scan dir.
If any plugin files were removed, unloads those plugins.
func (*Watcher) UnloadPlugin ¶
UnloadPlugin unloads a loaded plugin by ID.
