This merges the dart:uri library into dart:core removing the dart:uri library. Besides moving the library the Url class has been changed. * Removed existing Uri constructor as it was equivalent with Uri.parse * Remamed constructor Uri.fromComponents to Uri * Moved toplevel function encodeUriComponent to static method Uri.encodeComponent * Moved toplevel function decodeUriComponent to static method Uri.decodeComponent * Moved toplevel function encodeUri to static method Uri.encodeFull * Moved toplevel function decodeUri to static method Uri.decodeFull * Rename domain to host * Added static methods Uri.encodeQueryComponent and Uri.decodeQueryComponent * Added support for path generation and splitting * Added support for query generation and splitting * Added some level of normalization R=floitsch@google.com, lrn@google.com, nweiz@google.com, scheglov@google.com BUG= Review URL: https://codereview.chromium.org//16019002 git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@23266 260f80e4-7a28-3924-810f-c04153c831b5
This library provides the ability to parse, inspect, and manipulate stack traces produced by the underlying Dart implementation. It also provides functions to produce string representations of stack traces in a more readable format than the native StackTrace implementation.
Traces can be parsed from native StackTraces using Trace.from, or captured
using Trace.current. Native StackTraces can also be directly converted to
human-readable strings using Trace.format.
Here's an example native stack trace from debugging this library:
#0 Object.noSuchMethod (dart:core-patch:1884:25)
#1 Trace.terse.<anonymous closure> (file:///usr/local/google-old/home/goog/dart/dart/pkg/stack_trace/lib/src/trace.dart:47:21)
#2 IterableMixinWorkaround.reduce (dart:collection:29:29)
#3 List.reduce (dart:core-patch:1247:42)
#4 Trace.terse (file:///usr/local/google-old/home/goog/dart/dart/pkg/stack_trace/lib/src/trace.dart:40:35)
#5 format (file:///usr/local/google-old/home/goog/dart/dart/pkg/stack_trace/lib/stack_trace.dart:24:28)
#6 main.<anonymous closure> (file:///usr/local/google-old/home/goog/dart/dart/test.dart:21:29)
#7 _CatchErrorFuture._sendError (dart:async:525:24)
#8 _FutureImpl._setErrorWithoutAsyncTrace (dart:async:393:26)
#9 _FutureImpl._setError (dart:async:378:31)
#10 _ThenFuture._sendValue (dart:async:490:16)
#11 _FutureImpl._handleValue.<anonymous closure> (dart:async:349:28)
#12 Timer.run.<anonymous closure> (dart:async:2402:21)
#13 Timer.Timer.<anonymous closure> (dart:async-patch:15:15)
and its human-readable representation:
dart:core-patch Object.noSuchMethod
pkg/stack_trace/lib/src/trace.dart 47:21 Trace.terse.<fn>
dart:collection IterableMixinWorkaround.reduce
dart:core-patch List.reduce
pkg/stack_trace/lib/src/trace.dart 40:35 Trace.terse
pkg/stack_trace/lib/stack_trace.dart 24:28 format
test.dart 21:29 main.<fn>
dart:async _CatchErrorFuture._sendError
dart:async _FutureImpl._setErrorWithoutAsyncTrace
dart:async _FutureImpl._setError
dart:async _ThenFuture._sendValue
dart:async _FutureImpl._handleValue.<fn>
dart:async Timer.run.<fn>
dart:async-patch Timer.Timer.<fn>
You can further clean up the stack trace using Trace.terse. This folds
together multiple stack frames from the Dart core libraries, so that only the
core library method that was directly called from user code is visible. For
example:
dart:core Object.noSuchMethod
pkg/stack_trace/lib/src/trace.dart 47:21 Trace.terse.<fn>
dart:core List.reduce
pkg/stack_trace/lib/src/trace.dart 40:35 Trace.terse
pkg/stack_trace/lib/stack_trace.dart 24:28 format
test.dart 21:29 main.<fn>
dart:async Timer.Timer.<fn>
