Types

type BaseResourceType 

type BaseResourceType struct {
	Name string // The name of the type, e.g. 'git'.
}

BaseResourceType represents a resource type provided by workers.

It is created via worker registration. All creates are upserts.

It is removed by gc.BaseResourceTypeCollector, once there are no references to it from worker_base_resource_types.

func (BaseResourceType) Find 

func (brt BaseResourceType) Find(tx Tx) (*UsedBaseResourceType, bool, error)

func (BaseResourceType) FindOrCreate 

func (brt BaseResourceType) FindOrCreate(tx Tx) (*UsedBaseResourceType, error)

FindOrCreate looks for an existing BaseResourceType and creates it if it doesn't exist. It returns a UsedBaseResourceType.

Note that if the BaseResourceType already existed, there's a chance that it will be garbage-collected before the referencing ResourceConfig can be created and used.

This method can return ErrBaseResourceTypeAlreadyExists if two concurrent FindOrCreates clashed. The caller should retry from the start of the transaction.

	Description() string
}

ResourceUser encapsulates the ownership of a resource cache or config, by managing the resource_config_users and resource_cache_users tables.

These tables exist because resource caches and resource configs outlive most objects that reference them. They are referenced by multiple objects, and should only be garbage collectible when all uses go away. A simpler model of this would be simply incrementing/decrementing a 'uses' column on the cache or config itself, and garbage-collecting it if it's zero. However, this would not allow us to tell when a use is no longer needed, as they wouldn't be tied to who needed them. Having a separate 'uses' table allows us to know when a use is no longer valid, e.g. because it's a build that completed or a resource that is no longer being checked.

type UsedBaseResourceType 

type UsedBaseResourceType struct {
	ID   int // The ID of the BaseResourceType.
	Name string
}

UsedBaseResourceType is created whenever a ResourceConfig is used, either for a build, a resource in the pipeline, or a resource type in the pipeline.

So long as the UsedBaseResourceType's ID is referenced by a ResourceConfig that is in use, this guarantees that the BaseResourceType will not be removed. That is to say that its "Use" is vicarious.

type UsedResourceCache 

type UsedResourceCache struct {
	ID             int
	ResourceConfig *UsedResourceConfig
	Version        atc.Version
}

UsedResourceCache is created whenever a ResourceCache is Created and/or Used.

So long as the UsedResourceCache exists, the underlying ResourceCache can not be removed.

UsedResourceCaches become unused by the gc.ResourceCacheCollector, which may then lead to the ResourceCache being garbage-collected.

See FindOrCreateForBuild, FindOrCreateForResource, and FindOrCreateForResourceType for more information on when it becomes unused.

type UsedResourceConfig struct {
	ID                        int

}

UsedResourceConfig is created whenever a ResourceConfig is Created and/or Used.

So long as the UsedResourceConfig exists, the underlying ResourceConfig can not be removed.

UsedResourceConfigs become unused by the gc.ResourceConfigCollector, which may then lead to the ResourceConfig being garbage-collected.

See FindOrCreateForBuild, FindOrCreateForResource, and FindOrCreateForResourceType for more information on when it becomes unused.
