CompilerOutput values should never be mutated. Also includes minor
formatting change to the compile() method signature in line with the
style guide.
Minor housekeeping while I'm touching other bits of nearby code.
Wraps the compile function in a class injected via the global context,
which makes it easier to mock in unit tests -- specifically tests for
AOT snapshotting, which already require pretty significant amounts of
mock inputs.
New a11y traversal:
- sort direct sibling SemanticsNodes only
- use new sorting algorithm
- implement RTL
- test semantics in traversal order by default
- add AppBar traversal test
- breaking: remove nextNodeId/previousNodeId from the framework
- breaking: remove DebugSemanticsDumpOrder.geometricOrder
This avoids notifying the coverage collector that we
completed the test when in fact we timed out, which in
turn avoids a downstream exception caused by the fact
that coverage collector assumes it has a valid observatory
port by which it can gather coverage data.
Fixes https://github.com/flutter/flutter/issues/16839
This moves --vm_snapshot_data and --isolate_snapshot_data argument
hardcoding from GenSnapshot (a minimal wrapper around gen_snapshot
invocations) to Snapshotter.buildScriptSnapshot(). These arguments are
present in both AOT and script snapshots, but differ semantically: for
script snapshots they're inputs from the host engine artifacts
directory, for AOT snapshots they're outputs to the build directory.
* Support exposing the InspectorService over the Flutter
service extension protocol as well as the observatory protocol.
We will probably remove most of the observatory protocol support once a
couple versions of the Flutter IntelliJ plugin have shipped that use the
Flutter service extension protocol. The only reason to continue supporting
the observatory protocol is it will allow using the inspector when paused
at a breakpoint.
* Turn support for sync-async on in Flutter. With this feature
execution of async functions starts immediately instead of it
being delayed by one microtask tick.
* Address review comments.
* Adjust some stack trace expectations which are slightly different with
--sync-async turned on.
* Handle error count reported by frontend.
Extend compilation result from single string to a structure(string filename and integer error count).
* Use ?.
* Include engine roll with dart sdk roll.
* parse(onError) -> tryParse
* Make '?? throw' more readable and avoid issue with analyzer
* Fix test so it mocks compiler output including errors count
* A new UI is being designed to make the unused reload messaging clearer,
the UI will use the coverage data to highlight lines in the UI that were not executed during a reload.
In lieu of that we are turning off the unused reload messages experiment.
There were some issues in Dart2 also with this functionality
- source fingerprinting is not implemented in Dart2
- some additional synthetic functions are generated for invocation argument checking that are not appropriately filtered out.
Inlines the very small amount of work being done in _build() into
buildScriptSnapshot(). Eliminates a duplicate (and un-awaited) call to
_writeFingerprint.
* Sync .packages file as regular file.
Currently .packages file is treated specially as DevFSStringContent to accommodate package-file rewrite when it is sent to the device for dart1 compilation. In dart2 we need to treat .packages as regular file because from frontend perspective it's just a normal input file.
