The Headers directory is for public API exposed by a framework on Mac OS X.
The PrivateHeaders directory is a staging area for API that will be made public
some day. Note that WebCore.framework is not a public framework on Mac OS
X--it's an implementation detail of WebKit.framework--so the only Headers
(public API) directory between the two is WebKit.framework/Headers.
Since the DOMFile.h header is only in WebCore.framework/PrivateHeaders, you
only have to worry about putting DOMBlob.h there as well. The easiest way to
do this is to look for every place the DOMFile.h header is referenced in
WebCore. This is a bit tricky since File is so generic, so let's use
DOMFileList.h instead (and leave off the DOM prefix since that's added as
needed):
$ grep -l -r FileList WebCore
WebCore/bindings/objc/DOMInternal.h

WebCore/WebCore.scons

WebCore/WebCore.xcodeproj/project.pbxproj
WebCore/WebCoreSources.bkl
(Yes, I'm using an older tree because I'm in the middle of a bisect right now.)
Ignoring the places where it's used as an include or in the build system files,
we have:
WebCore/DerivedSources.cpp
WebCore/DerivedSources.make
So basically what you want to do is mimic how FileList is referenced in these
files for Blob. (Note that if there is no generated DOMBlobPrivate.h or
DOMBlobInternl.h, then you don't have to include those in the changes.)
It's also a good idea to mimic how FileList (or File) is used in the build
files as well. That will make it easier to prevent broken builds in various
ports when this change lands.
Hope that helps!

Thanks for all your information. Do you mean to add files into
MigrateHeaders.make as the following?
$(PRIVATE_HEADERS_DIR)/DOMBlob.h \
$(INTERNAL_HEADERS_DIR)/DOMBlobInternal.h \
What's the difference between adding into PRIVATE_HEADERS_DIR and adding into
PUBLIC_HEADERS_DIR? Blob interface is indeed the new superclass introduced for
the existing File interface per the File API spec. Since File has already been
added into PUBLIC_HEADERS_DIR, do we need to do the same thing for Blob?
I still can't get the generated DOMBlob.h and DOMBlobInternal.h copied into
PrivateHeaders of WebCore.framework. From the build output, I can see that
PBXCp is called for DOMFile.h, but not for DOMBlob.h. Do I need to change
other script file or makefile? Or I should change WebCore.xcodeproj to add the
generated header files. If so, which group should I add to?

All the magic for the Obj-C DOM headers happens in:

It should be added as a PrivateHeader first, if at all. Someone else will
have to address COM bindings since I don't know much about those.

Subject: [webkit-dev] How to add a new interface for ObjC bindings?
Hi,
I am working on adding Blob interface based on the latest File API spec. I
have one question about the various kinds of bindings we need to put up for
this new interface. I got JSC and V8 bindings generated and built
successfully. I have some problem with ObjC bindings. What's the right
procedure to add a new interface for ObjC bindings? I could see DOMBlob.h
being created under Debug/DerivedSources/WebCore, but not under
Debug/WebCore.framework/PrivateHeaders and Debug/WebKit.framework/Headers as
other interfaces do. How could I change WebCore.xcodeproj to add the build
steps for these? Any other things I need to pay attention to?
In addition, where do we use COM bindings? Is it only used when building
WebKit under Windows?
Thanks,
Jian
