stack_trace

Chain.forTrace() now returns a full stack chain for all StackTraces within Chain.capture(), even those that haven't been processed by dart:async yet.

Chain.forTrace() now uses the Dart VM's stack chain information when called synchronously within Chain.capture(). This matches the existing behavior outside Chain.capture().

Chain.forTrace() now trims the VM's stack chains for the innermost stack trace within Chain.capture() (unless it's called synchronously, as above). This avoids duplicated frames and makes the format of the innermost traces consistent with the other traces in the chain.

Use official generic function syntax.

Updated minimum SDK to 1.23.0.

Trace.foldFrames() and Chain.foldFrames() now remove the outermost folded frame. This matches the behavior of .terse with core frames.

Fix bug parsing a friendly frame with spaces in the member name.

Fix bug parsing a friendly frame where the location is a data url.

Add a Chain.disable() function that disables stack-chain tracking.

Fix a bug where Chain.capture(..., when: false) would throw if an error was emitted without a stack trace.

Add a when parameter to Chain.capture(). This allows capturing to be easily enabled and disabled based on whether the application is running in debug/development mode or not.

Deprecate the ChainHandler typedef. This didn't provide any value over directly annotating the function argument, and it made the documentation less clear.

new Chain.parse() now parses all the stack trace formats supported by new Trace.parse(). Formats other than that emitted by Chain.toString() will produce single-element chains.

new Trace.parse() now parses the output of Chain.toString(). It produces the same result as Chain.parse().toTrace().

new Trace.parse() and related constructors will no longer throw an exception if they encounter an unparseable stack frame. Instead, they will generate an UnparsedFrame, which exposes no metadata but preserves the frame's original text.

Properly parse native-code V8 frames.

When a null stack trace is passed to a completer or stream controller in nested Chain.capture() blocks, substitute the inner block's chain rather than the outer block's.

Add support for empty chains and chains of empty traces to Chain.parse().

Don't crash when parsing stack traces from Dart VM stack overflows.

Don't print the first folded frame of terse stack traces. This frame is always just an internal isolate message handler anyway. This improves the readability of stack traces, especially in stack chains.

Remove the line numbers and specific files in all terse folded frames, not just those from core libraries.

Make padding consistent across all stack traces for Chain.toString().

Add terse to LazyTrace.foldFrames().

Further improve stack chains when using the VM's async/await implementation.

Support VM frames without line or column numbers, which async/await programs occasionally generate.

Replace <<anonymous closure>_async_body> in VM frames' members with the terser <async>.

Unify the parsing of Safari and Firefox stack traces. This fixes an error in Firefox trace parsing.

Deprecate Trace.parseSafari6_0, Trace.parseSafari6_1, Frame.parseSafari6_0, and Frame.parseSafari6_1.

Add Frame.parseSafari.

Add a Chain.foldFrames method that parallels Trace.foldFrames.

Record anonymous method frames in IE10 as "<fn>".
