• Fix NoMethodError when SDK's dsn is nil #1433
• fix: Update protocol version to 7 #1434
  • Fixes #867

• Apply patches when initializing the SDK #1432

Sentry rate limits different types of events. And when rate limiting is enabled, it sends back a 429 response to the SDK. Currently, the SDK would then raise an error like this:

Unable to record event with remote Sentry server (Sentry::Error - the server responded with status 429
body: {"detail":"event rejected due to rate limit"}):

This change improves the SDK's handling on such responses by:

• Not treating them as errors, so you don't see the noise anymore.
• Halting event sending for a while according to the duration provided in the response. And warns you with a message like:

Envelope [event] not sent: Excluded by random sample

Now any outgoing requests will be recorded as a tracing span. Example:

With the new http_logger breadcrumbs logger:

config.breadcrumbs_logger = [:http_logger]

The SDK now records a new net.http breadcrumb whenever the user makes a request with the Net::HTTP library.

It'll determine whether the SDK should run in the debugging mode. Default is false. When set to true, SDK errors will be logged with backtrace.

• rate == 0 - Tracing enabled. Rejects all locally created transactions but respects sentry-trace.
• 1 > rate > 0 - Tracing enabled. Samples locally created transactions with the rate and respects sentry-trace.
• rate < 0 or rate > 1 - Tracing disabled.

  • Added background_worker_threads configuration option.

Sentry::Rack::Tracing is now removed. And Sentry::Rack::CaptureException has been renamed to Sentry::Rack::CaptureExceptions.

sentry-ruby now sends events asynchronously by default. The functionality works like this:

1. When the SDK is initialized, a Sentry::BackgroundWorker will be initialized too.
2. When an event is passed to Client#capture_event, instead of sending it directly with Client#send_event, we'll let the worker do it.
3. The worker will have a number of threads. And the one of the idle threads will pick the job and call Client#send_event.
   • If all the threads are busy, new jobs will be put into a queue, which has a limit of 30.
   • If the queue size is exceeded, new events will be dropped.

However, if you still prefer to use your own async approach, that's totally fine. If you have config.async set, the worker won't initialize a thread pool and won't be used either.

This functionality also introduces a new background_worker_threads config option. It allows you to decide how many threads should the worker hold. By default, the value will be the number of the processors your machine has. For example, if your machine has 4 processors, the value would be 4.

Of course, you can always override the value to fit your use cases, like

config.background_worker_threads = 5 # the worker will have 5 threads for sending events

You can also disable this new non-blocking behaviour by giving a 0 value:

config.background_worker_threads = 0 # all events will be sent synchronously
