dwds

• Expose middleware and handler.

Breaking Change: The AssetHandler will not automatically be added the DWDS handler cascade. You must now also add the middleware to your server's pipeline.

• Always bind to localhost for the local debug workflow.
• Fix an issue where breakpoints could cause DevTools to hang.

• Support using WebSockets for the debug (VM Service) proxy by passing useSseForDebugProxy: false to Dwds.start()

• Support nesting Dart applications in iframes.

• Depend on the latest package:built_value.

• Add temporary support for restoring breakpoints. Eventually the Dart VM protocol will clearly define how breakpoints should be restored.
• Depend on latest package:sse to get retry logic.
• Don't spawn DevTools if serveDevTools is false.
• UrlEncoder will also encode the base URI used by the injected client / Dart Debug Extension. ** Breaking Change ** serveDevTools is not automatically considered true if enableDebugExtensionis true.

• Properly wait for hot reload to complete with the legacy module system.
• Fix issue with getObject for a class with a generic type.

• Support optional argument urlEncoder that is used to encode remote URLs for use with the Dart Debug Extension.

• Handle getObject for primitives properly.
• Properly black box scripts if query parameters are provided.

• Fix issue with source map logic for the legacy module system.
• Allow setting breakpoints multiple times and just return the old breakpoint.
• Fix a bug with Maps that contain lists of simple types.

• The injected client's connection is now based off the request URI.
• Fix an issue where resuming while paused at the start would cause an error.
• Expose the ChromeDebugException class for error handling purposes.
• Expose the AppConnectionException class for error handling purposes.
• DevTools will now launch immediately and lazily sets up necessary state.
• Properly set pauseBreakpoints on kPauseBreakpoint events.
• Greatly improves handling of List, Map and IdentityMap instances.
• Lazily parse source maps to improve performance for large applications.

• Deobfuscate DDC extension method stack traces.
• Properly get all libraries with the legacy module system.

• Correctly set Isolate state if debugging is initiated after the application has already started.

• Account for root directory path when using package: URIs with DartUri.

• Fix a bug where we would try to create a new isolate even for a failed hot restart. This created a race condition that would lead to a crash.
• Don't attempt to write a vm service request to a closed connection.
  • Instead we log a warning with the attempted request message and return.
• Make all close methods more robust by allowing them to be called more than once and returning the cached future from previous calls.
• Add explicit handling of app not loaded errors when handling chrome pause events.

• DWDS.start now requires an AssetHandler instead of applicationPort, assetServerPort and applicationTarget.
• Expose a BuildRunnerAssetHandler which proxies request to the asset server running within build runner.
• Support the Legacy Module strategy through the injected client.
• Support DDK sourcemap URIs.
• Update SDK dependency to minimum of 2.5.0.

Bug Fixes:

• Fix handling of chrome pause events when we have no isolate loaded yet.

• Capture any errors that happen when handling SSE requests in the DevHandler and return an error response to the client code.
  • Log error responses in the client to the console.
• Handle empty Chrome exception descriptions.

• Add new required parameter enableDebugging to Dwds.start. If false is provided, debug services will not run. However, reload logic will continue to work with the injected client.
• Handle injected client SSE errors.
• Handle a race condition when the browser is refreshed in the middle of setting up the debug services.

• Properly set the pauseEvent on the Isolate.
• Fix a race condition with Hot Restarts where the Isolate was not created in time for pause events.

• Fix issue where certain required fields of VM service protocol objects were null.
• Properly set the exceptionPauseMode on the Isolate.
• Depend on the latest DevTools.

• Fix issue where certain required fields of VM service protocol objects were null.

• Fix issue where certain required fields of VM service protocol objects were null.
• Properly display Closure names in the debug view.

• Fix an issue where missing source maps would cause a crash. A warning will now be logged to the console instead.
• Depend on the latest package:webkit_inspection_protocol.

• Fix an issue where we source map paths were not normalized.
• Added a check to tests for the variable DWDS_DEBUG_CHROME to run Chrome with a UI rather than headless.
• Catch unhandled errors in client.js and recommend using the --no-injected-client flag for webdev users.
• Add support for an SSE connection with Dart DevTools.
• Rename wsUri to uri on DebugConnection to reflect that the uri may not be a websocket.
• Depend on latest package:vm_service.

• Move data abstractions from package:webdev into package:dwds.
• Move debugging related handlers from package:webdev into package:dwds.
• Move injected client from package:webdev into package:dwds.
• Create new public entrypoint dwds.dart. Existing public API services.dart is now private.

• Add support for getScript for paused isolates.
• Add support for onRequest and onResponse listeners for the vm service.

• Add support for scope in evaluate calls.

• Improve error reporting for evals, give the full JS eval in the error message so it can be more easily reproduced.

• Change the exposed type on DebugService to VmServiceInterface

• Support setExceptionPauseMode.

• Added custom tokens to the wsUri for increased security.
  • Treating this as a breaking change because you now must use the wsUri getter to get a valid uri for connecting to the service, when previously combining the port and host was sufficient.

• Initial version
