Functions

func DistributionName 

func DistributionName(distType int) string

DistributionName returns the distribution ID string for the given type. Returns empty string for unknown types.

func GenerateAliasFromURL 

func GenerateAliasFromURL(url string) string

GenerateAliasFromURL generates an alias from a URL

func GetHostPatternMap 

func GetHostPatternMap() map[*regexp.Regexp][]Rule

GetHostPatternMap returns a map from URL pattern regex to cache rules for all registered distributions. Used by the proxy to match requests and apply rules.

func ReloadDistributionsConfig 

func ReloadDistributionsConfig(configPath string)

ReloadDistributionsConfig resets the global registry to built-in distributions, then loads and applies distributions from the given config file path. When configPath is empty, Load() still tries default paths (./config/distributions.yaml, ./distributions.yaml, /etc/apt-proxy/distributions.yaml, etc.). Safe to call at startup and on SIGHUP/API reload.

Types

type AliasTemplateData 

type AliasTemplateData struct {
