Comment on attachment 284103 [details] Rebasing View in context: https://bugs.webkit.org/attachment.cgi?id=284103&action=review Great work. There are just a few things left to address: 1) EWS failures 2) WebCore/DerivedSources.make has some issues 3) Given that wrapper generation is now exclusive with other generation, I think the option should be named --wrappers-only. Sorry for being picky about the name, I think I did not understand the patch as well when I made the current suggestion. > Source/JavaScriptCore/ChangeLog:13 > + Added new built-in test file to cover the case of several concatenating several guards in generated WebCore wrapper files.

Nit: 'things' > Source/JavaScriptCore/Scripts/generate-js-builtins.py:88 > + generators.append(BuiltinsSeparateHeaderGenerator(model, object)) Ok, so now I'm a little confused. Is --wrappers exclusive with generating normal builtins? It's not clear from the code and change log whether it's additive or subtractive. If it's subtractive, --wrappers-only might make more sense. > Source/WebCore/CMakeLists.txt:3762 > + OUTPUT ${DERIVED_SOURCES_WEBCORE_DIR}/WebCoreJSBuiltins.cpp This would be easier to follow if the output files for wrappers actually had Wrappers in the name somehow. > Source/WebCore/CMakeLists.txt:3768 > COMMAND ${PYTHON_EXECUTABLE} ${JavaScriptCore_SCRIPTS_DIR}/generate-js-builtins.py --wrappers --framework WebCore --output-directory ${DERIVED_SOURCES_WEBCORE_DIR} ${WebCore_BUILTINS_SOURCES} I see, so it would make sense to call it --wrappers-only, as you need to call it a second time. > Source/WebCore/DerivedSources.make:1328 > +WebCore_BUILTINS_WRAPPER : WebCore_BUILTINS_DEPENDENCIES_LIST Is WebCore_BUILTINS_WRAPPER a valid target?

Thanks for the review. > 1) EWS failures Win did not succeed in applying the patch. I saw this error in another patch so I do not think this is related to this one.

I am fine changing the name. I chose this name to be close to JSC names (JSCBuiltins.h/.cpp).

I changed it to "passed" to be consistent with run_tests.

I'll change that but cannot it cause an issue if the first file is ok but one of the other file needs to be regenerated (like if it is accidentally deleted)? > (Don't you wish we could just stick to CMake? ;)) Definitely... 8-)

Unfortunately we are stuck with this problem as long as we use Make. AFAIK there is no good workaround for multiple files derived from one invocation. If you delete the .mm or .cpp from JS DOM bindings, it will also not get regenerated. > > > (Don't you wish we could just stick to CMake? ;)) > > Definitely... 8-)
