[reload_test] Adding support for VM hot reload tests. VM hot reload are run via: 1) We first emit a dill for every generation ahead of time (full dill on gen 0, incremental deltas subsequently). 2) We start a VM process at generation 0. 3) The VM process runs until it hits a `hotReload` command. It then uses the VM service protocol to connect to itself and reload the next generation. 4) The VM exits when the next generation isn't found. * Adds config files to reload tests that allow runtime filtering. * Implements VM-side hot reloading * Adds several VM-specific hot reload tests Change-Id: I1c6ad5c4eed426a0189c1b4af31297c9c1dba717 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/359200 Reviewed-by: Nicholas Shahan <nshahan@google.com> Commit-Queue: Mark Zhou <markzipan@google.com> Reviewed-by: Sigmund Cherem <sigmund@google.com>
Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
