Bug 74599 – Enable the [Supplemental] IDL on AppleWebKit and AppleWin

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Kentaro Hara]

We have enabled the [Supplemental] IDL on Chromium and are planning to enable it on all platforms (Meta bug 72138). In this bug, we enable it on AppleWebKit.

I uploaded a WIP patch. I am planning to land it in the following steps:

[1] Fix CodeGeneratorJS.pm for custom getters and setters with the [Supplemental] IDL.
[2] Move settingsForWindow(), webkitAudioContext() and webSocket() in JSDOMWindowCustom.cpp into JSDOMWindowWebAudioCustom.cpp and JSDOMWindowWebSocketCustom.cpp, for modularization.
[3] Make a change on Derivedsources.make.

Unfortunately, this line takes 13 seconds in my Mac environment (although it is executed only when any of IDL files is updated).

As commented above, the line is equivalent to 'echo $(IDL_FILES_LIST) > $(ALL_IDLS_TEMPFILE)', but the line realizes it by executing "echo idl_file >> $(ALL_IDLS_TEMPFILE)" for *each* IDL file. This is because 'echo $(IDL_FILES_LIST) > $(ALL_IDLS_TEMPFILE)' exceeds the OS limit of command-line argument count, and 'echo "$(IDL_FILES_LIST)" > $(ALL_IDLS_TEMPFILE)' exceeds the OS limit of command-line argument bytes...

Any better idea?

Is there a way in Make to break up IDL_FILES_LIST into chunks?

It is possible. I'll do it in the upcoming patch then.

Should we store the list of IDL files in a file outside of DerivedSources.make?  Is there a way for the makefile to read them in?

It is also possible. Rather than splitting $(IDL_FILES_LIST) into chunks, preparing the file might be better.

### By the way, we will need to prepare the file that lists all IDL files for *each* platform.

Do you mean each build system?  Generally, the list of IDL files for every platform are the same.  Ideally we'd have one list that was used by all the build systems, but having a separate list for each build system is ok because that's what we have today.

Ah, yes, I meant it.

I got it. Ideally we would have one file that lists all IDL files used by all the build systems, and an array that lists "exceptional" IDL files in each build script. Then in most cases we just need to touch the one file when we want to add a new IDL file. I'd like to do this refactoring after we enable the [Supplemental] IDL on all the build systems. Thanks.
