Bug 37369 – [GTK] Enable building whatever already exists of WebKit2

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Gustavo Noronha (kov)]

So we can participate better in the design/architecture of the new API layer that we will very likely want to use, we should get something building as soon as possible. This bug tracks our efforts on that front.

non-working work in progress patch

I started playing around with this, but I have to go away for a while, so I thought I'd upload what I already did. I haven't been too careful about correctness yet, just poked, and massaged stuff. I am trying to get a convenience library called libwebkit2 built from the Platform/ and Shared/ directories, essentially.

Notes:

* It looks like the plan is to avoid using config.h in WebKit2, but I have added it in some places in this first try;
* I am using OS(LINUX) in places that need a non-toolkit-specific, platform-specific typedef, for now, without really looking at its correctness in detail;
* Some files use "WebCore/<File>.h" paths for inclusion, that may or may not be related to changes that were done to WebCore's directory structure and will be landed in the future. Some examples:

#include <WebCore/FloatRect.h>
#include <WebCore/PlatformString.h>

The platforms that are currently supported all support prefix headers, so there’s no need to explicitly do prefix includes in this manner.  We may decide that it is a good idea to match the explicit style we use in JavaScriptCore and WebCore, or we may find that it is necessary because some platforms do not support prefix headers.

This is a Mac OS X-style framework include.  We’ll need to work out which approach we want to use to handle including WebCore headers in a cross-platform manner within WebKit.

[Gustavo Noronha (kov)]

Hey Mark, thanks for the comments!

(In reply to comment #2)
> The platforms that are currently supported all support prefix headers, so

Cool. Is the idea using one prefix header for all platforms, or having each platform define its own? WebKit2Prefix.h seems to be windows-specific, and WebKit2_Prefix.pch mac-specific. Should I make a  new one for Linux, or add preprocessor checks to one of the existing?

My current approach has been removing all the path, and including only the filename but that may not be the best approach, given that many files have similar names in both WebKit2, and Webcore, and depending only on include path precedence to fix that may not be the best thing. So, what do you suggest?

[Gustavo Noronha (kov)]

First try!

So, this gets us a libwebkit2.la library built with a small part of what is already available of WebKit2. It has a few fixes to include paths, and such that we need to discuss better how to handle to avoid ambiguity. We also need to discuss our approach to the prefix headers.

s/similar/equal/ I had that problem with Arguments.h, which exists in
JavaScriptCore/runtime and WebKit2/Platform/CoreIPC, while playing around.

[Gustavo Noronha (kov)]

Actually, regarding the Identifier for the connection, I am considering using a named unix socket. We could use dbus, but given the fact that CoreIPC has its own IPC model, and its own serialization of data types, and messages, I'm not sure what the advantage of using dbus would be. We would only be sending opaque messages containing a string with the serialized data. The alternative is to replace CoreIPC with dbus on our ports, but I think we'd lose a whole lot of the work that is already in place, and would have to reimplement a lot of the IPC code. Anyone knows better?

[Evan Martin]

My (vague) understanding of dbus is that all messages get routed through the message daemon, which is overhead you will not want for low-latency high-throughput IPC.

Chrome uses named pipes on Windows and anonymous socketpair() on Unix.  The nice thing about anonymous file descriptors is that you don't end up with junk on your disk after crashes -- they clean themselves up.

http://src.chromium.org/cgi-bin/gitweb.cgi?p=chromium.git;a=blob;f=ipc/ipc_channel_posix.cc;h=f6b19f7e0aa69ac6ce9870c84bc52f8c17f53bac;hb=HEAD
discusses it

[Gustavo Noronha (kov)]

It is possible to use dbus peer-to-peer, with no server routing, yes. I also thought of socketpair, but CoreIPC in its current state looks simpler to implement if you have a named resource. Haven't looked into too much detail though.

I'm not up to speed on DBus, but it's definitely useful to have a low-level transport as much as possible. Ideally you will want to be able to pass shared memory and file descriptors over this channel (FDs are not needed right now, but will probably useful once you get to proxying.)

some more WIP - IPC work

I don't even claim this builds - I'm just feeling bad about sitting on top of this work without being able to work full-throttle on it =).

[Gustavo Noronha (kov)]

Useful information, from andersca on the mailing list:

"Right now WebCore needs to be built with some different flags (ENABLE_EXPERIMENTAL_SINGLE_VIEW_MODE=1 
and WTF_USE_WEB_THREAD=1), but the goal is that the same WebCore should be able to support both WebKit and WebKit2 (and on the mac, both WebKit frameworks will link against the same WebCore framework)."

[Anders Carlsson]

We (Sam Weinig) have started work on getting rid of the ENABLE_WEB_THREAD define.

Looks like we need to work out how we want to do cross-framework includes before deciding what to do about this patch.  Please post an updated patch once we've come to consensus on that topic.

Does the include dir need to be in the toplevel actually? I also wonder if there's some way to move that into the WebKit2 makefile. I suppose defining the rule multiple times won't do the right thing ;)

config.h need not be the first header inclusion because we follow framework style includes. 
As for the other errors, GTK naming convention is followed.

Great patch! I haven't had time to go through it in detail, but I believe we want all new code to follow WebKit coding style. The only exception are names that are exposed to the public API.

Initial Implementation of WebKit2 Gtk Port

View in context: https://bugs.webkit.org/attachment.cgi?id=71620&action=review

Generally the patch looks very promising for me, however I do not know much about GTK and I am not a reviewer.
I think the MiniBrowser part should be separated to another patch, this is quite big even without that.
The main problem I see is that there are too many ifdefs in common code. Those should be avoided somehow.

> WebCore/platform/network/soup/cache/webkit/soup-cache.h:7
>   *

I have never saw the expressions "Portions Copyright" or any prefix before "all rights reserved" in WebKit before, so maybe
you should omit those for convenience.

> WebKit2/Platform/Module.h:69
>  

I do not think you should add copyright for that amount of changes, but of course it is your decision.

> WebKit2/Platform/CoreIPC/gtk/ConnectionGtk.cpp:97
> +    return true;

this should be "return m_socket > 0" as I see

We should avoid ifdefs in common code. You can send this message from invalidateBackingStore which is a platform method.

> +#endif

We should get rid of the ifdefs somehow. Is there a way to avoid the gtk specialization of didUpdate? I see the reason of
that but maybe you can do it in another way. One think that had been came to my mind is to use info().id for the key in
xIDMap and introduce a platform method that would be called from ChunkedUpdateArea::didUpdate, for example
'void platformDidUpdate(const DrawingAreaInfo&)'

Please try to fix this. I had similar problems that could be solved by including npruntime_internal.h instead of npruntime.h
in some files. You should precompile it and find where the macro is coming from.

As I sad above, this should be avoided.

Ok. Since these files do not expose any public API, we will change the naming convention to match the WebKit style and re-submit the patch.

invalidate would be too early to send a confirmation as the handler in the WebProcess would delete the GdkPixmap and the next function in the UI Process, drawUpdateChunkIntoBackingStore would use this GdkPixmap.

info().id refers to the DrawingArea id. Each DrawingArea may result in multiple UpdateChunk's. So, this id cannot be the key in this case.
I could think of another alternative(i'm not sure if that is a good idea) ie to define ID() in UpdateChunk() for all the platforms and use it wherever required.

This is an incorrect FIXME comment that we left. Sorry for that. We just wanted to prevent WebCore/PluginView.h inclusion while compiling this file.

This can be moved to ChunkedUpdateDrawingAreaGtk.cpp, however, the declarations in the .h file need to be there.

WebKit2 GTK Patch after rework

View in context: https://bugs.webkit.org/attachment.cgi?id=71887&action=review

Phwew! This is a big patch. Thanks for contributing it. I've reviewed the build changes so far. Hopefully I'll find some time later to look over the rest of the patch.

Instead of repeating all of these source and flag lists, is it possible to create a variable in configure.ac and use it much like WEBKITGTK_API_MAJOR_VERSION?

> JavaScriptCore/GNUmakefile.am:-54
> -	JavaScriptCore/API/APICast.h \

Why have you removed these headers from the source list?

> JavaScriptCore/GNUmakefile.am:-71
> -	JavaScriptCore/API/JSRetainPtr.h \

Same question.

> JavaScriptCore/GNUmakefile.am:-76
> -	JavaScriptCore/API/OpaqueJSString.h \

And here.

> WebCore/ChangeLog:8
> +        No new tests. (OOPS!)

This line should be replaced with an explaination of what sort of testing is possible, if at all.

Talking to Xan today, it seems that the bindings/gobject files only include webkitdefines.h for the WEBKIT_API visibility markers. Can you try to simply eliminate the webkitdefines.h include and reproduce WEBKIT_API in bindings/gobject. That would eliminate a lot of the conditional stuff below.

> WebCore/GNUmakefile.am:-2916
> -	WebCore/storage/IDBIndexBackendInterface.h \

Why remove this?

> WebCore/GNUmakefile.am:-2927
> -	WebCore/storage/IDBObjectStoreBackendInterface.h \

And this?

> WebCore/platform/network/soup/cache/webkit/soup-cache.h:6

It's fine for your copyright message to omit "Portions" and "Except as provided below,". If I understand correctly, these are implied.

> WebKit2/GNUmakefile.am:481
> +# Copy header files to DerivedSources

I guess I feel that 'include' makes sense as the destination instead of DerivedSources/WebKit2/include. These files aren't generated, they are just copied.

> WebKit2/GNUmakefile.am:483
> +copy_wc_headers := $(filter %.h, $(webcore_sources))
> +webcore-headers: $(copy_wc_headers)

This is sort of the reverse of what I would expect. I think the rule should have the verb. Something like this:

webcore_headers := $(filter %.h, $(webcore_sources))
copy-webcore-headers: $(webcore_headers)

I have this preference for the rest of these copying rules too.

> WebKit2/GNUmakefile.am:538
> +	$(WebKit2)/UIProcess/Plugins \
> +    $(WebKit2)/WebProcess/Plugins \
> +	$(WebKit2)/WebProcess/WebPage \

The indentation is a little funky here.

> WebKit2/GNUmakefile.am:541
> +vpath %.messages.in = $(MESSAGE_INPUT_PATH)

Is it possible to list these directly in the vpath directive instead of spinning them off into a separate variable?

> WebKit2/GNUmakefile.am:543
> +MESSAGE_GEN_SCRIPT = \

I'd rather this be in lower-case since it's not global. Something like message_gen_scripts.

> WebKit2/GNUmakefile.am:592
> +# .PHONY: include-headers

I think you need to add all of the header copying targets to the .PHONY rule.

I recommend you to generate forwarding headers instead of copying.
One of the benefits is dependency tracking.
WebKitTools/Scripts/generate-forwarding-headers.pl should fit your needs,
if it is not than you can hack on that.

Great tip, Balazs! I definitely agree with this.

Bare minimum changes for building GTK port of WebKit2

The attached patch includes Makefile changes for building either WebKit1 or WebKit2.
As part of the WebKit2 build, it builds all platform independent files, and stubbed out platform dependent files.
Rest of the code will be attached as independent compilation units to each of the specific bugs raised. These bugs are marked as dependent on 37369.

[Amruth Raj]

The build failure is because MiniBrowser files are separated into a different patch and these files are included in the main Makefile.
The patch is marked obsolete and a new patch is attached. Please ignore this error.

GObject separation is still required for WebKit2 build.

Now that we are generating the forward headers, I hope the location should be fine :)

Just to clarify, this patch is simply build changes plus GTK+-specific WebKit2 files stubbed out.

I know that. Still, an almost 80k patch is pretty unwieldy regardless of what it contains.

Bare minimum changes for building GTK port of WebKit2

View in context: https://bugs.webkit.org/attachment.cgi?id=72201&action=review

Looks good, but I think the build file changes can be simplified even more.

> GNUmakefile.am:74
> +webcoregtk_gdom_sources :=
> +webcoregtk_gdom_cppflags :=

I don't think these are necessary.

> GNUmakefile.am:82
> +webkit2gtk_static_h_api :=
> +webkit2_cppflags :=
> +webkit2gtk_cppflags :=

GTK+ is the only autotools user and probably will be for the future. I think we can get rid of  webkit2gtk_sources and webkit2gtk_cppflags.

> GNUmakefile.am:84
> +webkit2_built_nosources :=

I don't think this variable needs to exist. See below.

> GNUmakefile.am:827
> +if !ENABLE_WEBKIT2
>  # Older automake versions (1.7) place Plo files in a different place so we need
>  # to create the output directory manually.
>  all-local: stamp-po
>  	$(mkdir_p) $(top_builddir)/$(DEPDIR)/DerivedSources
> +endif #!ENABLE_WEBKIT2

Why is this work-around for older versions of automake conditional on the WebKit2 build?

> WebCore/GNUmakefile.am:88
> +webcoregtk_gdom_cppflags += \

I don't understand the need for webcoregtk_gdom_cppflags here. Why not just add it directly to webcoregtk_cppflags?

> WebCore/GNUmakefile.am:3651
> +webcoregtk_gdom_sources += \

Please just add these directly to webcoregtk_sources and scrap the webcoregtk_gdom_sources variable. I think keeping the number of makefile variables low is key to keeping it understandable.

> WebCore/platform/network/soup/cache/webkit/soup-cache.h:30
> +#if !defined(ENABLE_WEBKIT2_BUILD)
>  #if BUILDING_GTK__
>  #include <webkit/webkitdefines.h>
>  #else

Instead of a workaround for WebKit2, why not just define WEBKIT_API unconditionally to simplify the #ifdefs?

> WebKit2/GNUmakefile.am:3
> +ForwardingHeaders := $(GENSOURCES_WEBKIT2)/include
> +HttpStack := @HTTP_STACK@

If these need to be in a make variable, please move them down near where you use them.

> WebKit2/GNUmakefile.am:9
> +	$(srcdir)/WebKit2/Shared/API/c/WKArray.h \
> +	$(srcdir)/WebKit2/Shared/API/c/WKBase.h \
> +	$(srcdir)/WebKit2/Shared/API/c/WKCertificateInfo.h \
> +	$(srcdir)/WebKit2/Shared/API/c/WKData.h \

Why not use the $(WebKit2) variable defined above for this source list?

> WebKit2/GNUmakefile.am:401
> +	$(webkit2_built_nosources)

I think I'd rather see generate-forwarding-headers here explicitly rather than having a webkit2_built_nosources variable.

> WebKit2/GNUmakefile.am:471
> +vpath %.messages.in = $(WebKit2)/PluginProcess $(WebKit2)/UIProcess $(WebKit2)/UIProcess/Plugins $(WebKit2)/WebProcess/Plugins $(WebKit2)/WebProcess/WebPage $(WebKit2)/WebProcess

Please split this across multiple lines, if possible.

Very well. The build file changes clock in around 48K alone (likely they will be a bit smaller once the stubbed out source files are removed). In your opinion, should Ravi and Amruth split the build file changes into even smaller patches? We would prefer not to check in a broken WebKit2 build, if possible.

You can easily land the stubbed out source files before landing the build file changes. Besides, the WebKit2 GTK+ build is already broken (for some definition of broken).

> You can easily land the stubbed out source files before landing the build file changes. Besides, the WebKit2 GTK+ build is already broken (for some definition of broken).

That dips a bit too far into philosophy this early in the afternoon for my tastes (can something that doesn't exist be broken), but I think your solution makes a lot of sense.

This is not possible. The older automake targets points to targets stamp-po etc which are defined in WebKit/gtk/po/GNUmakefile.am folder. Since, we are excluding the entire WebKit/ folder itself for WebKit2, the inclusion of this rule is not possible.

Very nice patch. Thanks for updating it. Just a couple more lingering issues. I think it's very close.

> WebCore/ChangeLog:8

This line should be removed.

This will actually break the GTK+ Windows build. You should probably include the MSVC support here too.

> WebKit2/GNUmakefile.am:580
> +# Ensure that the prefix header is built before

You are no longer using using a precompiled header, so I think this comment is out of date. :)

> WebKit2/WebKit2Prefix.h:33

Why do you need to conditionally include these?

> WebKit2/WebProcess/WebCoreSupport/WebFrameLoaderClient.cpp:-33
> -#include "PluginView.h"

I think the right way to solve this problem is to only include the big list of -I directories in WebCore if we are building WebKit 1. Otherwise, we'll probably keep running into this issue. Do you mind trying that?

> +HTTP_STACK="soup"
> +WEBKITGTK_PC_NAME=${WEBKITGTK_PC_NAME}2

If HTTP_STACK is hardcoded, why not just remove it? Generally we have standardized on soup. If you want to re-add support for cURL, maybe we can address it in another patch? I think it's much more feasible for WebKit2, if you really need it for something.

Reverted this file. Solved the issue by building WebKit2 as a convenience target and then linking with actual webkit target as per our discussion yesterday.

Makefile changes to building the WebKit2 GTK port based on comments given by Martin Robinson on 9th December.

[Ravi Phaneendra Kasibhatla]

Hi Martin Robinson,

Based on our discussion yesterday, I have attached the new patch with 2 changes.
1) Removed unwanted variables from GNUmakefile.am - just kept the variables for built_sources
2) Removed the WebCore/bindings/gobject files from WebCore/GNUmakefile.am and added them to WebKit/gtk/GNUmakefile.am. Now there is no if !ENABLE_WEBKIT2 inside WebCore/GNUmakefile.am

This looks good to me. I'd love it if a WebKit2 developer could confirm that the change to WebKit2/WebKit2Prefix.h is sane. Perhaps we should leave a comment there explaining the situation before landing this.

It was added so that we can build WebKit2 through the "build-webkit" script. We could land this separately also (once complete WebKit2 patch is in).

I've uploaded a modified version of the patch fixing the issues I mentioned as well with a few other changes:
