var DefaultClient = newClient(nil)

Initialize a default *Client instance

var MaxQueueBuffer = 100

The maximum number of packets that will be buffered waiting to be delivered. Packets will be dropped if the buffer is full. Used by NewClient.

Functions

func Capture 

func Capture(packet *Packet, captureTags map[string]string) (eventID string, ch chan error)

Capture asynchronously delivers a packet to the Sentry server with the default *Client. It is a no-op when client is nil. A channel is provided if it is important to check for a send's success.

func CaptureError 

func CaptureError(err error, tags map[string]string, interfaces ...Interface) string

CaptureErrors formats and delivers an error to the Sentry server using the default *Client. Adds a stacktrace to the packet, excluding the call to this method.

func CaptureErrorAndWait 

func CaptureErrorAndWait(err error, tags map[string]string, interfaces ...Interface) string

CaptureErrorAndWait is identical to CaptureError, except it blocks and assures that the event was sent

func CaptureMessage 

func CaptureMessage(message string, tags map[string]string, interfaces ...Interface) string

CaptureMessage formats and delivers a string message to the Sentry server with the default *Client

func CaptureMessageAndWait 

func CaptureMessageAndWait(message string, tags map[string]string, interfaces ...Interface) string

CaptureMessageAndWait is identical to CaptureMessage except it blocks and waits for the message to be sent.

func CapturePanic 

func CapturePanic(f func(), tags map[string]string, interfaces ...Interface) (interface{}, string)

CapturePanic calls f and then recovers and reports a panic to the Sentry server if it occurs. If an error is captured, both the error and the reported Sentry error ID are returned.

func ClearContext 

func ClearContext()

func Close 

func Close()

func IncludePaths 

func IncludePaths() []string

func ProjectID 

func ProjectID() string

func RecoveryHandler 

func RecoveryHandler(handler func(http.ResponseWriter, *http.Request)) func(http.ResponseWriter, *http.Request)

Recovery handler to wrap the stdlib net/http Mux. Example: 

http.HandleFunc("/", raven.RecoveryHandler(func(w http.ResponseWriter, r *http.Request) {
	...
}))

func Release 

func Release() string

func SetDSN 

func SetDSN(dsn string) error

Sets the DSN for the default *Client instance

func SetHttpContext 

func SetHttpContext(h *Http)

func SetIncludePaths 

func SetIncludePaths(p []string)

func SetRelease 

func SetRelease(release string)

SetRelease sets the "release" tag on the default *Client

func SetTagsContext 

func SetTagsContext(t map[string]string)

func SetUserContext 

func SetUserContext(u *User)

func URL 

func URL() string

func Wait

Types

type Client 

type Client struct {

	// DropHandler is called when a packet is dropped because the buffer is full.
	DropHandler func(*Packet)
	// contains filtered or unexported fields

NewClient constructs a Sentry client and spawns a background goroutine to handle packets sent by Client.Report.

Deprecated: use New and NewWithTags instead

NewWithTags constructs a new Sentry client instance with default tags.

func (*Client) Capture 

func (client *Client) Capture(packet *Packet, captureTags map[string]string) (eventID string, ch chan error)
