Bug 15406 – Generated files missing from WebCore's Xcode project file

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[David Kilzer (:ddkilzer)]

The following shell script demonstrates files missing from the Xcode project file for WebCore:

for F in `ls WebKitBuild/Debug/DerivedSources/WebCore`; do \
    if [ -z "`grep $F WebCore/WebCore.xcodeproj/project.pbxproj`" ]; then \
        echo $F; \
    fi; \
done

Missing files:

DOMCSSStyleSheetPrivate.h
DOMEventPrivate.h
DOMHTMLCollectionPrivate.h
DOMHTMLEmbedElementPrivate.h
DOMHTMLIFrameElementPrivate.h
DOMHTMLObjectElementPrivate.h
DOMHTMLSelectElementPrivate.h
DOMSVGPointInternal.h
DOMSVGRectInternal.h
DOMTextEventInternal.h
JSHTMLInputElementBaseTable.cpp
JSSVGAnimatedPoints.cpp
JSSVGAnimatedPoints.h

NOTE: This may be worthwhile to run on the feature branch as well.

Note that this file is actually used as a header file since it's a #include in WebCore/bindings/js/JSHTMLInputElementBase.cpp.

Proposed fix.

I removed JSSVGAnimatedPoints.h from DerivedSources.make since the generated code was not being used anyway.

I did not rename JSHTMLInputElementBaseTable.cpp to JSHTMLInputElementBaseTable.h, even though this file name would make more sense since that's the way the file is used.

Added Eric to CC list in case he has any comments to add.

Hum..
SVGAnimatedPoints is an interface which is used by SVGPolyElement (not exposed in the bindings)
which is the base class for SVGPolyLineElment and SVGPolygonElement

I'm not sure if it needs to be compiled or not, given that it's only an interface.

I wonder if it's possible to make this script a commit-hook for *just* the xcode file (w/o slowing down the rest of svn commits).

You need to make sure to export/migrate the objective-c headers and make sure they migrated in WebKit

If they weren't migrated before, why would they need to be migrated now?  (I'm not trying to be obtuse, just curious as to why they would need to be migrated.)

Oh, are they considered SPI and thus should be a part of the WebKit.framework?

[Timothy Hatcher]

DOM*Private.h is SPI and should be migrated. The other files are just internal to WebCore and should not be migrated to WebKit.

Per Comment #9, I need to make sure these headers are copied over.

Not sure if that's done in the WebCore or WebKit project file (or in a script).  Need to investigate further.

[Timothy Hatcher]

It is done by WebKit/MigrateHeaders.make. Just add the files to the list at the top, and make sure to migrate them to the WebKit private headers directory.

[David Kilzer (:ddkilzer)]

Missing files for r27253:

DOMCSSStyleSheetPrivate.h
DOMEventPrivate.h
DOMHTMLCollectionPrivate.h
DOMHTMLEmbedElementPrivate.h
DOMHTMLIFrameElementPrivate.h
DOMHTMLObjectElementPrivate.h
DOMHTMLSelectElementPrivate.h
DOMSVGException.mm
DOMSVGExceptionInternal.h
DOMTextEventInternal.h
JSHTMLInputElementBaseTable.cpp
JSSVGAnimatedPoints.cpp
JSSVGAnimatedPoints.h

Tim, is there a rule for copying header files in the MigrateHeaders.make file?  There seem to be a lot of missing files if every generated *Private.h and *Internal.h file is supposed to be migrated this way:

$ for F in `ls WebKitBuild/Debug/DerivedSources/WebCore/*Private.h`; do \
    if [ -z "`grep $F WebKit/MigrateHeaders.make`" ]; then \
        echo $F; \
    fi; done | wc -l
      33

$ for F in `ls WebKitBuild/Debug/DerivedSources/WebCore/*Internal.h`; do \
    if [ -z "`grep $F WebKit/MigrateHeaders.make`" ]; then \
        echo $F; \
    fi; done | wc -l
     236

Oops!  Those weren't correct.  These are:

$ for F in `ls WebKitBuild/Debug/DerivedSources/WebCore/ | grep 'Private.h$'`; do \
    if [ -z "`grep $F WebKit/MigrateHeaders.make`" ]; then \
        echo $F; \
    fi; done | wc -l
       0

$ for F in `ls WebKitBuild/Debug/DerivedSources/WebCore/ | grep 'Internal.h$'`; do \
    if [ -z "`grep $F WebKit/MigrateHeaders.make`" ]; then \
        echo $F; \
    fi; done | wc -l
     110

[Timothy Hatcher]

There is isn't a hard/fast rule. Only headers that are needed as public and private OS X headers need migrated. Internal headers should not be migrated.

Patch v2

Changes since Patch v1:

- Removed DOMSVGException.h in addition to JSSVGAnimatedPoints.h from WebCore/DerivedSources.make.
- Don't add DOMSVGPointInternal.h and DOMSVGRectInternal.h to the project file since those were already fixed.
- Added *Private.h files to the Copy Generated Files Build Phase in WebCore.
- Modified WebKit/MigrateHeaders.make to add the same *Private.h files that were added to the Copy Generated Headers Build Phase in WebCore.

Note that I did a clean build (wiped WebKitBuild dir) of r27257 and everything built fine.
