• Drop support for Ruby 2.4 and note that Ruby 3.0 is also unsupported

• quota_project can be set via library configuration

This is a major update that removes the "low-level" client interface code, and instead adds the new google-cloud-debugger-v2 gem as a dependency. The new dependency is a rewritten low-level client, produced by a next- generation client code generator, with improved performance and stability.

This change should have no effect on the high-level interface that most users will use. The one exception is that the (mostly undocumented) client_config argument, for adjusting low-level parameters such as RPC retry settings on client objects, has been removed. If you need to adjust these parameters, use the configuration interface in google-cloud-debugger-v2.

Substantial changes have been made in the low-level interfaces, however. If you are using the low-level classes under the Google::Cloud::Debugger::V2 module, please review the docs for the new google-cloud-debugger-v2 gem. In particular:

• Some classes have been renamed, notably the client class itself.
• The client constructor takes a configuration block instead of configuration keyword arguments.
• All RPC method arguments are now keyword arguments.

• Fix segfaults on Ruby 2.7

• Fix a few broken links

• Adjusted some default timeout and retry settings

• Support separate project setting for quota/billing

• Update copyright year

• Update minimum runtime dependencies

This release requires Ruby 2.4 or later.

• Clarify which Google Cloud Platform environments support automatic authentication

• Update lower-level client network configuration

• Support overriding of service endpoint

• Fix max threads setting in thread pools
  • Thread pools once again limit the number of threads allocated.
• Update documentation links

• Support overriding service host and port in the low-level client.

• Google::Cloud::Env provides additional configuration options including retries and cache control
• Add VERSION constant

• Add AUTHENTICATION.md guide.
• Update documentation for common types.
• Extract gRPC header values from request.

• Fix bug (typo) in retrieving default on_error proc.

• Fix conversion code for ErrorEvent and Debugee.
  • Prepare for changes in JSON serialization coming in google-protobuf 3.7.

• Update concurrent-ruby dependency

• Add Debugger on_error configuration.
• Update Transmitter
  • Add dependency on current-ruby.
  • Add Transmitter#on_error method.
  • Update Transmitter documentation.
• Make use of Credentials#project_id
  • Use Credentials#project_id If a project_id is not provided, use the value on the Credentials object. This value was added in googleauth 0.7.0.
  • Loosen googleauth dependency Allow for new releases up to 0.10. The googleauth devs have committed to maintaining the current API and will not make backwards compatible changes before 0.10.

• Update network configuration.

• Update documentation.
  • Change documentation URL to googleapis GitHub org.
• Fix circular require warning.

• Add missing documentation files to package.

• Update documentation.

• Update documentation.

• Fix issue when disabling Stackdriver components with Rails.env.production.
• Add documentation for enabling gRPC logging.

• Delay starting the debugger agent until the first request to ensure it happens after workers are forked. Should prevent grpc from malfunctioning in this case.

• Use Google Cloud Shared Configuration.
• Fix for mutation detection using Ruby 2.5.
• Support disabling mutation detection in debugger evaluation.

• Update google-gax dependency to 1.0.

• Fix credentials verification bug in Railtie.

• Add Google::Cloud::Debugger::Credentials class.
• Rename constructor arguments to project_id and credentials. (The previous arguments project and keyfile are still supported.)
• Document Google::Auth::Credentials as credentials value.
• Add Debugger Agent Design Document.
• Updated google-gax (grpc, google-protobuf), googleauth dependencies.

• Improve Breakpoint tracer performance by not tracking C function calls in file tracing.
• Add a backoff behavior in the debuggee registration to reduce spamming requests when registrations fail.

• Print captured exception from asynchronous worker threads.

• Support single file Rack-based applications.
• Support none-Rack-based Ruby applications.
• API Breaking Change:
  • module_name initialization parameter renamed to service_name
  • module_version initialization parameter renamed to module_version

• Optimize breakpoint evaluation memory usage by adopting shared variable table.
• Update breakpoint to error state if the breakpoint is set at an invalid position or if condition evaluation fail with an error.
• Set errored variable evaluation to error state.
• Restrict the amount of time spent on evaluating breakpoints within each rack application request.
• Restrict total memory usage on collecting variables within each breakpoint evaluation. Prioritize memory allocation to user defined variables over local variables.

• stackdriver-core 1.2.0 release

• Update GAPIC configuration to exclude UNAVAILABLE errors from automatic retry.

• Introduce new Google::Cloud::Debugger.configure instrumentation configuration interface.

• Fixed Google::Cloud::Debugger::Railtie initialization on non-GCP environments to not interfere with Rails startup

• First release
