Types

type ActivesGetter 

type ActivesGetter interface {
	// GetActives returns the number of active TLFs and active hosts in the
	// past dur.
	GetActives(dur time.Duration) (activeTlfs int, activeHosts int, err error)
}

ActivesGetter holds necessary data to generate number of active TLFs or hosts.

type ActivityStatsEnabler 

type ActivityStatsEnabler struct {
	// Storer specifies a backend storer that a StatsReporter should use to
	// store data necessary for generating activity-based stats.
	Storer ActivityStatsStorer
	// Durations specifies a slice of durations that activity-based stats
	// should be about. For example, [1h, 1d, 1week] makes the StatsReporter
	// should report hourly, daily, and weekly active stats.
	Durations []NameableDuration
	// Interval specifies how often the activity-based stats should be
	// reported.
	Interval time.Duration
}

ActivityStatsEnabler describes what backend storer a StatsReporter should use for activity-based stats, and how the stats should be generated.

type ActivityStatsStorer 

type ActivityStatsStorer interface {
	// RecordActives records that tlfID and host has just been active.
	RecordActives(tlfID tlf.ID, host string)

	// GetActivesGetter returns a ActivesGetter from current state of the
	// ActivityStatsStorer.
	GetActivesGetter() (ActivesGetter, error)
}

ActivityStatsStorer defines a set of methods to record activities based on TLF ID and host names.

func NewFileBasedActivityStatsStorer 

func NewFileBasedActivityStatsStorer(
	rootPath string, logger *zap.Logger) (ActivityStatsStorer, error)

NewFileBasedActivityStatsStorer creates an ActivityStatsStorer that stores activities on a local filesystem.

NOTE that this is meant to be for development and testing only and does not scale well.

func NewMySQLActivityStatsStorer 

func NewMySQLActivityStatsStorer(
	db *sql.DB, logger *zap.Logger) ActivityStatsStorer

NewMySQLActivityStatsStorer creates an ActivityStatsStorer that stores activities on a MySQL database.

type CacheableFS 

type CacheableFS struct {
	// contains filtered or unexported fields
}

CacheableFS is a wrapper around a *libfs.FS and a subdir. Use Use() to get a *libfs.FS that roots at subdir. This essentially delays "cd"ing into subdir, and is useful for caching a *libfs.FS object without the downside of caching a libkbfs.Node that can be obsolete when it's renamed or removed.

func (CacheableFS) EnsureNoSuchFileOutsideRoot 

func (fs CacheableFS) EnsureNoSuchFileOutsideRoot(name string) (err error)

EnsureNoSuchFileOutsideRoot walks from the sub dir that this FS is configured to use back all the way to the TLF root, and try to find a file named `name`. If the file is found, an error is returned.

For example, if a subdir /dir1/dir2/dir3 is configured as root dir, calling this function makes sure none of /a/b/{name}, /a/{name}, and /{name} exist. Though /a/b/c/{name} can exist.

func (CacheableFS) IsObsolete 

func (fs CacheableFS) IsObsolete() bool

IsObsolete returns true if fs has reached the end of life, because of a handle change for example. In this case user should not use this fs anymore, but instead make a new one.

func (CacheableFS) Use 

func (fs CacheableFS) Use() (*libfs.FS, error)

Use returns a *libfs.FS to use.

type CertStoreType 

type CertStoreType string

CertStoreType is a type for specifying if and what cert store should be used for acme/autocert. 

const (
	NoCertStore      CertStoreType = ""
	DiskCertStore    CertStoreType = "disk"
	KVStoreCertStore CertStoreType = "kvstore"
)

Possible cert store types.

type CtxKBPTagKey 

type CtxKBPTagKey int

CtxKBPTagKey is the type used for unique context tags within kbp and libpages. 

const (
	// CtxKBPKey is the tag key for unique operation IDs within kbp and
	// libpages.
	CtxKBPKey CtxKBPTagKey = iota
)

type ErrDomainBlockedInBlacklist

Error implements the error interface.

type ErrDomainNotAllowedInWhitelist 

type ErrDomainNotAllowedInWhitelist struct{}

ErrDomainNotAllowedInWhitelist is returned when the server is configured with a domain whitelist, and we receive a HTTP request that was sent to a domain that's not in the whitelist.

func (ErrDomainNotAllowedInWhitelist) Error 

func (ErrDomainNotAllowedInWhitelist) Error() string

Error implements the error interface.

type ErrKeybasePagesRecordNotFound 

type ErrKeybasePagesRecordNotFound struct{}

ErrKeybasePagesRecordNotFound is returned when a domain requested doesn't have a kbp= record configured.

func (ErrKeybasePagesRecordNotFound) Error 

func (ErrKeybasePagesRecordNotFound) Error() string

Error implements the error interface.

type ErrKeybasePagesRecordTooMany 

type ErrKeybasePagesRecordTooMany struct{}

ErrKeybasePagesRecordTooMany is returned when a domain requested has more than one kbp= record configured.

func (ErrKeybasePagesRecordTooMany) Error 

func (ErrKeybasePagesRecordTooMany) Error() string

Error implements the error interface.

type NameableDuration 

type NameableDuration struct {
	Duration time.Duration
	Name     string
}

NameableDuration is a wrapper around time.Duration that allows customized String() encoding.

func (NameableDuration) String 

func (d NameableDuration) String() string

String returns d.Name if it's not empty, or d.Duration.String().

type Root 

type Root struct {
	Type            RootType
	TlfType         tlf.Type
	TlfNameUnparsed string
	PathUnparsed    string
}

Root defines the root of a static site hosted by Keybase Pages. It is normally constructed from DNS records directly and is cheap to make.

func ParseRoot 

func ParseRoot(str string) (*Root, error)

ParseRoot parses a kbp= TXT record from a domain into a Root object.

func (*Root) MakeFS 

func (r *Root) MakeFS(
	ctx context.Context, log *zap.Logger, kbfsConfig libkbfs.Config) (
	fs CacheableFS, tlfID tlf.ID, shutdown func(), err error)

MakeFS makes a CacheableFS from *r, which can be adapted to a http.FileSystem (through ToHTTPFileSystem) to be used by http package to serve through HTTP. Caller must call Use() to get a usable FS.

type RootLoader 

type RootLoader interface {
	LoadRoot(domain string) (root Root, err error)
}

RootLoader is the interface for loading a site root.

func NewDNSRootLoader 

func NewDNSRootLoader(log *zap.Logger) RootLoader

NewDNSRootLoader makes a new RootLoader backed by DNS TXT record. It caches the root for a short period time. This is the RootLoader that should be used in all non-test scenarios.

When loading from DNS, it does so with following steps:

  1. Construct a domain name by prefixing the `domain` parameter with "_keybase_pages." or "_keybasepages". So for example, "static.keybase.io" turns into "_keybase_pages.static.keybase.io" or "_keybasepages.static.keybase.io".
  2. Load TXT record(s) from the domain constructed in step 1, and look for one starting with "kbp=". If exactly one exists, parse it into a `Root` and return it.

There must be exactly one "kbp=" TXT record configured for domain. If more than one exists, an ErrKeybasePagesRecordTooMany{} is returned. If none is found, an ErrKeybasePagesRecordNotFound{} is returned. In case the user has some configuration that requires other records that we can't foresee for now, other records (TXT or not) can co-exist with the "kbp=" record (as long as no CNAME record exists on the "_keybase_pages." or "_keybasepages." prefixed domain of course).

If the given domain is invalid, the domain name constructed in this step will be invalid too, which causes Go's DNS resolver to return a net.DNSError typed "no such host" error.

Examples for "static.keybase.io", "meatball.gao.io", "song.gao.io", "blah.strib.io", and "kbp.jzila.com" respectively: 

_keybase_pages.static.keybase.io TXT "kbp=/keybase/team/keybase.bots/static.keybase.io"
_keybase_pages.meatball.gao.io   TXT "kbp=/keybase/public/songgao/meatball/"
_keybase_pages.song.gao.io       TXT "kbp=/keybase/private/songgao,kb_bot/blah"
_keybase_pages.blah.strib.io     TXT "kbp=/keybase/private/strib#kb_bot/blahblahb" "lah/blah/"
_keybase_pages.kbp.jzila.com     TXT "kbp=git@keybase:private/jzila,kb_bot/kbp.git"
