Types ¶
type CRConfig ¶
type CRConfig struct {
ContentServers map[tc.CacheName]struct {
DeliveryServices map[tc.DeliveryServiceName][]string `json:"deliveryServices"`
CacheGroup string `json:"cacheGroup"`
Type string `json:"type"`
} `json:"contentServers"`
DeliveryServices map[tc.DeliveryServiceName]struct {
Topology tc.TopologyName `json:"topology"`
Matchsets []struct {
Protocol string `json:"protocol"`
MatchList []struct {
Regex string `json:"regex"`
} `json:"matchlist"`
} `json:"matchsets"`
} `json:"deliveryServices"`
Topologies map[tc.TopologyName]struct {
Nodes []string `json:"nodes"`
}
}
CRConfig is the CrConfig data needed by TOData. Note this is not all data in the CRConfig. TODO change strings to type?
type Regexes ¶
type Regexes struct {
DirectMatches map[string]tc.DeliveryServiceName
DotStartSlashDotFooSlashDotDotStar map[string]tc.DeliveryServiceName
RegexMatch map[*regexp.Regexp]tc.DeliveryServiceName
}
Regexes maps Delivery Service Regular Expressions to delivery services. For performance, we categorize Regular Expressions into 3 categories: 1. Direct string matches, with no regular expression matching characters 2. .*\.foo\..* expressions, where foo is a direct string match with no regular expression matching characters 3. Everything else This allows us to do a cheap match on 1 and 2, and only regex match the uncommon case.
func NewRegexes ¶
func NewRegexes() Regexes
NewRegexes constructs a new Regexes object, initializing internal pointer members.
func (Regexes) DeliveryService ¶
func (d Regexes) DeliveryService(domain, subdomain, subsubdomain string) (tc.DeliveryServiceName, bool)
DeliveryService returns the delivery service which matches the given fqdn, or false.
type TOData ¶
type TOData struct {
DeliveryServiceRegexes Regexes
DeliveryServiceServers map[tc.DeliveryServiceName][]tc.CacheName
DeliveryServiceTypes map[tc.DeliveryServiceName]tc.DSTypeCategory
ServerCachegroups map[tc.CacheName]tc.CacheGroupName
ServerDeliveryServices map[tc.CacheName][]tc.DeliveryServiceName
ServerTypes map[tc.CacheName]tc.CacheType
}
TOData holds CDN data fetched from Traffic Ops.
type TODataThreadsafe ¶
type TODataThreadsafe struct {
// contains filtered or unexported fields
}
TODataThreadsafe provides safe access for multiple goroutine writers and one goroutine reader, to the encapsulated TOData object. This could be made lock-free, if the performance was necessary
func NewThreadsafe ¶
func NewThreadsafe() TODataThreadsafe
NewThreadsafe returns a new TOData object, wrapped to be safe for multiple goroutine readers and a single writer.
func (TODataThreadsafe) Fetch ¶
func (d TODataThreadsafe) Fetch(to towrap.TrafficOpsSessionThreadsafe, cdn string) error
Fetch gets the CRConfig from Traffic Ops, creates the TOData maps, and atomically sets the TOData. TODO since the session is threadsafe, each TOData get func below could be put in a goroutine, if performance mattered
func (TODataThreadsafe) Get ¶
func (d TODataThreadsafe) Get() TOData
Get returns the current TOData. Callers MUST NOT modify returned data. Mutation IS NOT threadsafe If callers need to modify, a new GetMutable() should be added which copies.
func (TODataThreadsafe) Update ¶
func (d TODataThreadsafe) Update(to towrap.TrafficOpsSessionThreadsafe, cdn string) error
Update updates the TOData data with the last fetched CDN
