- Move expression evaluation to ddc in preparation for google3 - Added server to ddc to handle update and compileExpression requests - Added tests - Added 'experimental-output-compiled-kernel' option to ddc to generate full kernel files only for compiled libraries, and store with '.full.dill' extension - Added AssetFileSystem to communicate to the asset server in the debugger - Made expression_compiler_worker work with full kernel files, so removed invalidation of current file to improve performance - Made expression_compiler_worker reuse already loaded imports to avoid reading them from source in the incremental compiler - Updated tests to work with DDC (for simulating webdev) - Disabled tests that work with bazel kernel worker for now as it does not generate full dill files yet - Addressed code review comments from the prototype version: https://dart-review.googlesource.com/c/sdk/+/157005 Details: Currently, in flutter tools, expression evaluation is supported via expression compilation, which is done by the incremental compiler in the frontend server. The same incremental compiler is used for initial application compilation, incremental code compilation for hot reload, and any number of expression compilation requests. In google3, the apps are typically too large to be compiled as a whole in memory by the frontend server. Build in google3 is currently done by blaze, as a distributed build using a task dependency graph. Build tasks output kernel outline files as an interface between components produced by individual tasks. We are proposing an implementation of the expression compilation in google3 that is taking advantage of full kernel files produced by the build (supporting build changes to follow). This change introduces a small server based on dev_compiler, which can handle following requests: - update: load full kernel for given modules (done on app start) - compileExpression: compile expression in a given library and module (done when paused on a breakpoint) Expression compilation uses previously loaded kernel files for the application component and its dependencies to compile an expression.
