Types

type MemoryCache

type MemoryCache map[string]*Node

MemoryCache maintains a mapping of dinghyfiles and their dependencies

func NewMemoryCache

func NewMemoryCache() MemoryCache

NewMemoryCache initializes a new cache

func (MemoryCache) Dump

func (c MemoryCache) Dump()

Dump prints the cache, used for debugging

func (MemoryCache) GetRoots

func (c MemoryCache) GetRoots(url string) []string

GetRoots returns all roots for a given leaf

func (MemoryCache) SetDeps

func (c MemoryCache) SetDeps(parent string, deps []string)

SetDeps sets the dependencies for a parent

func (MemoryCache) UpstreamURLs

func (c MemoryCache) UpstreamURLs(url string) ([]string, []string)

UpstreamURLs returns two arrays: 1) Array of all upstream URLs from a URL 2) Array of only the root URLs (dinghyfiles) for a given URL

type Node

type Node struct {
	URL      string
	Children []*Node
	Parents  []*Node
}

Node represents either a dinghyfile or a module. The URL is the github URL for the dinghyfile or module that can optionally include the commit hash for versioning purposes.

func NewNode

func NewNode(url string) *Node

NewNode allocates a new node in the cache

func (*Node) String

func (n *Node) String() string

type RedisCache

type RedisCache struct {
	Client *redis.Client
	Logger *log.Entry
	// contains filtered or unexported fields
}

RedisCache maintains a dependency graph inside Redis

func NewRedisCache

func NewRedisCache(redisOptions *redis.Options, logger *log.Logger, ctx context.Context, stop chan os.Signal) *RedisCache

NewRedisCache initializes a new cache

func (*RedisCache) Clear

func (c *RedisCache) Clear()

Clear clears everything

func (*RedisCache) GetRoots

func (c *RedisCache) GetRoots(url string) []string

GetRoots grabs roots

func (*RedisCache) SetDeps

func (c *RedisCache) SetDeps(parent string, deps []string)

SetDeps sets dependencies for a parent
