Yes, the RGBA32Buffer inside ImageDecoder.h. I agree that eventually it should be moved into its own place, but for now it's not there, and it's hard to remember that the WinCE port happens to have a completely differently-named implementation living off in a separate place. When I make changes to the cross-platform version, I'll likely break your build. > > Some of your files have vim formatting comments at bottom.

I'll make it shared code with RGBA32Buffer. But, this bug is supposed to only contain new files. The changes in ImageDecoder.h will go to another bug. To reduce the naming change, I'll "typedef RGBA32Buffer ImageFrameSink;", what do you think? 136029 24 pkasting 2009-07-30 14:54:14 -0700 (In reply to comment #23) > OK.

The changes in ImageDecoder.h will go to another bug. > To reduce the naming change, I'll "typedef RGBA32Buffer ImageFrameSink;", what > do you think? Hmm... I'm trying to figure out what the best landing sequence here is, since those ImageDecoder changes might take a while to work through. Seems like there are a lot of options: * Land ImageFrameSink as-is, in graphics/wince. Perhaps add comments atop ImageDecoder.h/ImageFrameSink.h noting the similarities between the two, in hopes that people won't break your port. File a new bug about merging the two together. * Break RGBA32Buffer out of ImageDecoder.h into its own header, but don't change anything else about it. Put your versions alongside this header/implementation. Not sure what the names of each should be at that point. Hope that this provides enough motivation for people to combine the two eventually. * Wait until RGBA32Buffer gets pulled out of ImageDecoder and moved over to graphics/. Modify RGBA32Buffer directly, and rename it something more accurate. (Although TBH I despise the name "ImageFrameSink" as it feels somewhere between meaningless and inaccurate. Just "ImageFrame" would probably be better.) * Various other combinations of the above It doesn't seem fair to either force you to refactor all the image classes or make you wait on somebody else to do it (although it would be nice to have help refactoring things...). Perhaps the first option is the best thing for the WinCE port. Even though I suggested modifying RGBA32Buffer, I have the feeling it's going to take some time and effort to examine the changes you've made and figure out how to best merge them in to the code everyone else is using (hopefully with few if any #ifdefs). So maybe a strategy that gets your files into the tree is better... 137014 25 34068 yong.li.webkit 2009-08-04 09:08:56 -0700 Created attachment 34068 7) Color, Gradient, Image call startAnimation() first 137016 26 yong.li.webkit 2009-08-04 09:13:52 -0700 (In reply to comment #24) Yes, the image frame sink stuff is a very big change.

FWIW, I'm in the midst of actively working on the Image subsystem, and I have speculative plans to split RGBA32Buffer out of ImageDecoder.h, rename it, and move it to graphics/ in a week or two. That might make it slightly easier to modify so that it will work for WinCE too (or it might not help much, not sure). 137066 28 yong.li.webkit 2009-08-04 11:13:24 -0700 (In reply to comment #27) > (In reply to comment #26) > > Yes, the image frame sink stuff is a very big change.

It's good to split RGBA32Buffer out, create more generic interface as image decoding buffer, and allow different implementations for different ports or products. Actually our ImageFrameSink is such an interface, and it should be very easy to implement ImageFrameSink with current RGBA32Buffer or Vector<char>. Would you please consider making new RGBA32Buffer as close to ImageFrameSink.h as possible? That could make merging my code easier :) 137069 29 staikos 2009-08-04 11:25:41 -0700 (In reply to comment #28) > It's good to split RGBA32Buffer out, create more generic interface as image > decoding buffer, and allow different implementations for different ports or > products.

The very first patch will just move it somewhere without changing the implementation. The next thing I'd like to do afterward is take a hard look at your ImageFrameSink and see if I can figure out how to add those capabilities to the existing cross-plaform code in a way that doesn't require tons of #ifdefs. > it should be > very easy to implement ImageFrameSink with current RGBA32Buffer Yes, one possibility before this functionality gets included directly (or perhaps in place of doing that?) would be to make your ImageFrameSink a subclass of this other class and simply extend it. 138075 31 33813 eric 2009-08-07 13:05:10 -0700 Comment on attachment 33813 1) image encoders Why do you need image encoders?

More information is needed in your ChangeLog. I think this is obvious. We need image encoders to support the canvas feature of saving image buffer to data url. See platform/image-encoders.

He suggested to move wince image encoders to this folder. Note that I never actually looked at the code. It would be even more awesome if the cross-platform bits were factored into a common file and then you had platform-specific extensions for skia and wince. If you're not planning on doing that before landing, are you planning to do it after landing? (I did a similar "refactor after landing" with the skia image decoders.) 138094 34 yong.li.webkit 2009-08-07 13:25:20 -0700 (In reply to comment #33) > (In reply to comment #32) > > (In reply to comment #31) > > > Also, you should get pkasting to look at this as he's most familiar with our > > > encoder/decoder stuff. > > > > Yes, we had talks.

(I did a similar "refactor after landing" with the skia image > decoders.) Yes, that would be awesome. The platform-specific issue is that the image format in source buffer is differently. Except that, our png encoder is just a clone of the skia png encoder. And our jpeg encoder can be used for other ports with a little bit modification, too. I would like to do it when I get time. 138154 35 33814 eric 2009-08-07 14:35:42 -0700 Comment on attachment 33814 2) SharedBitmap r- for lack of ChagneLog.

The WinCE patches have been an undue burden on the WebKit review queue as of late. I know, because I just read through it twice in 2 days and reviewed most of the 50 bugs we just closed out. :) I just ask that you work with the people you hire to improve the quality of patches posted to the review queue. I'm very happy to review patches form the WinCE folks. I just ask that they have a prayer of passing review before being posted. In the case of this bug none of the patches even had ChangeLogs, let alone passing WebKit style. In other bugs much of my r-ing of WinCE patches was about copy/paste code and patch size. It seems that at least the lack of ChangeLogs, style issues (check-webkit-style) and patch size should be easy for you to work with the people you've hired to work on WebKit to solve.

I would like to say that your repeated notes of check-webkit-style seem out of place to me. I know that Yong has been using this tool in submitting these patches. What's more, we have contributed an equal or greater amount of the current check-webkit-style checks and bugfixes as anyone else in the process of this upstreaming project. In spite of all this, you should note that check-webkit-style is just a tool and an error prone one at that. It has many false positives and it doesn't catch lots of style violations that it should.

Peter Kasting has pointed out that we should split the ChangeLog into different patches. We're going to do that anyway. But the source files are still good to review. Recently we post a lot of patches for WINCE port, because we have worked on this for more than 1.5 years, and just started upstreaming. But we don't expect that they can be committed in short time. We're not pushing you. But this kind of review ( r- with "No ChangeLog" ) won't take more than 0.5 min, right? Thanks for reviewing and commenting. 138193 47 mjs 2009-08-07 15:38:40 -0700 Eric has a good point that the system works better if patches are submitted with simple structural issues addressed. However, we should also make an effort to be courteous to new contributors, even if their first few patches have some basic mistakes. 138412 48 34391 yong.li.webkit 2009-08-08 13:12:31 -0700 Created attachment 34391 1) Image encoders 138413 49 34392 yong.li.webkit 2009-08-08 13:27:45 -0700 Created attachment 34392 2) SharedBitmap 138414 50 34393 yong.li.webkit 2009-08-08 13:29:07 -0700 Created attachment 34393 2) SharedBitmap 138415 51 34394 yong.li.webkit 2009-08-08 13:32:28 -0700 Created attachment 34394 3) ImageBuffer 138416 52 34395 yong.li.webkit 2009-08-08 13:36:52 -0700 Created attachment 34395 4) ImageFrameSink (used as image decoding buffer) 138419 53 34396 yong.li.webkit 2009-08-08 13:40:48 -0700 Created attachment 34396 5) MediaPlayer Written by Crystal Zhang 138423 54 34398 yong.li.webkit 2009-08-08 13:47:12 -0700 Created attachment 34398 6) Path PlatformPath 138425 55 34400 yong.li.webkit 2009-08-08 13:53:55 -0700 Created attachment 34400 7) Image ImageSource 138426 56 34401 yong.li.webkit 2009-08-08 13:54:27 -0700 Created attachment 34401 8) Color Gradient 138457 57 34391 pkasting 2009-08-08 17:27:07 -0700 Comment on attachment 34391 1) Image encoders Since Eric has asked for some of my comments in the past, I decided to comment on the first patch on here as if I were a reviewer.

I haven't used this technique with the WTF library so I'm pretty ignorant of its implementation detail. If you don't declare the 2k capacity, is the vector guaranteed to heap-allocate no matter the size, or would it still do something smart for you under the hood? How was 2k picked here -- was it arbitrary, or based on some data? Is there a downside other than stack usage?

I cannot speak with perfect authority, but I did spend five years as a compiler engineer, and my impression is that your code is if anything less likely to be optimized than my suggestion. (It's very likely the two generate the same code.) It would be awesome if you had some sort of testcase that exercised a lot of this code in a way that could be timed. Of course benchmarking inner loops is tricky given the effects of processor caches and the like, but such a thing would be immensely valuable in the future, where I believe we'll try to rearchitect the Image system to include the capabilities you need more directly, instead of as something of a fork (like you've had to maintain until now). It would help reassure me that, for example, replacing some particular pixel-writing loop with a call to an inlined function did not actually hurt performance. Otherwise, the best we can do is probably manual assembly inspection which is pretty error-prone when determining real perf. > > > + for (; pixel < pixelEnd; ) { > > > > I find "while (pixel < pixelEnd) {" clearer. > > Seems webkit prefer "while" to "for".

In the case that compiler doesn't optimize, *foo++ may result this kind of machine code 1) move foo to register 2) save *foo to register or some variable 3) increase the register by one that keeps foo 4) save the register back to stack But if ++foo is called later, then = *foo moves foo to register once, and later ++foo does that again. Of course, most compilers may be smart enough to optimize this when they find foo is not used in-between *foo and ++foo. Long time ago, it was said smaller C/C++ code could result fast machine code. This may be the reason why there's "++" operator in C. Because "foo += 1" is even more readable. But the point is not that, I have no problem with choosing either one. I just think it may be a time waste on such small things. Each C++ programmer has his personal programming style, because everyone has different mind. I agree with that some basic coding style rules do help, but too many brainwashing things just reduce the fun of C++ programming and waste time. I believe that you would write very different code if you implemented it. If the reviewer was me, probably you would be asked to change *foo and ++foo to *foo++. > > > > > + for (; pixel < pixelEnd; ) { > > > > > > I find "while (pixel < pixelEnd) {" clearer. > > > > Seems webkit prefer "while" to "for".

Precision in syntax is a virtue... In this case, I agree that while() is better. But what's your opinion about "while(true)" vs. "for(;;)"? 138503 61 yong.li.webkit 2009-08-09 07:22:31 -0700 (In reply to comment #59) > (In reply to comment #58) > > > > +struct jpeg_dest_mgr { > > > > + struct jpeg_destination_mgr pub; > > > > + Vector<char> buffer; > > > > + Vector<char>* dump; > > > > +}; > > > > > > Naming style (here and below) > > > > I see { should be in the next line here.

The existing JPEGImageDecoder.cpp does the same: struct decoder_error_mgr { struct jpeg_error_mgr pub; /* "public" fields for IJG library*/ jmp_buf setjmp_buffer; /* For handling catastropic errors */ }; About "m_" for the members in struct: this is a good example that one reviewer says this, but another says opposite. Sigh... I'm going to use: class JpegDestinationManager { public: Foo m_foo; ... }; Will anyone say that the data member shouldn't be public? or suggest me to change back to struct? 138505 62 eric 2009-08-09 07:34:47 -0700 Seems the style guide needs some updating: http://webkit.org/coding/coding-style.html it does not cover the struct Foo { int bar; } case. (Whether it should be "bar" vs. "m_bar"). 138556 63 pkasting 2009-08-09 14:25:40 -0700 (In reply to comment #60) > Heap allocation is slower than stack allocation. 2K is arbitrary. I know heap allocation is slower :). You didn't answer my question. Does WTF::Vector have any code in it to automatically stack-allocate for smaller vectors? (There are certainly Gecko classes that do...) I would definitely comment in the code about 2k being arbitrary, and why you're doing it. > In the case that compiler doesn't optimize, *foo++ may result this kind of > machine code > 1) move foo to register > 2) save *foo to register or some variable > 3) increase the register by one that keeps foo > 4) save the register back to stack > > But if ++foo is called later, then = *foo moves foo to register once, and later > ++foo does that again. For RISC chips that need to have something in a register to update it, the compiler will allocate |foo| to a register for the body of the loop because it's the loop index. For chips (like x86, IIRC... x86 assembly is not my strong suit) that can directly modify stack variables, no movement in and out of a register is necessary. The reason I suggest putting ++pixel in the for() declaration is that it's much clearer to a reader what's happening in the loop -- you see the test and iteration on one line, not broken into pieces and hidden in a later statement's side effect. From an optimization perspective, this kind of code helps the compiler convert the loop into a decrementing loop, unroll it, etc. > But the point is not that, I have no problem with choosing either one. I just > think it may be a time waste on such small things. There is no WebKit style rule on this one, but I don't consider clarity a small thing, and I'll always suggest what I think is the clearest code. Statements with side effects are inherently less clear, even if (as in this case) the code is simple enough that it's not too much more difficult to determine what the code is doing. Note that writing your loop iteration as suggested also makes it slightly easier if we convert the code to use some kind of iterator or other interface to get at the source data -- which we will likely need to do when we combine this code with the other platforms'. See also how the image decoders changed to not using direct memory access in their inner loops, in favor of an inline function in the header to do the right thing depending on the platform. > In this case, I agree that while() is better. But what's your opinion about > "while(true)" vs. "for(;;)"? I have used both. while(true) is significantly more common, and thus easier for most people to read, and therefore slightly better IMO.

I don't know what WebKit style is on that last question. Google style (which I only mention because it's the set of style rules I happen to know well) would suggest you use a struct rather than a class for something that's purely a container of public members, and personally I agree; I would leave it as a struct and change the names as you suggested.

Just a guess, no other reason. 2K seems not too big, compared to other big buffer on stack, and canvas objects narrower than 683 can benefit. > > There is no WebKit style rule on this one, but I don't consider clarity a small > thing, and I'll always suggest what I think is the clearest code.

Well, as I mentioned, += 1 might be clearer that ++. Making code too much readable just makes me feel that I'm not doing C++, or I'm doing C++ in MS style :) I may be sick at the point. But still, too many restrictions and requirements on such things make programming no more interesting, because one tries to write code as he was another person, tries to follow another person's mind. Although he can still do it, but there's no fun. > > > > In this case, I agree that while() is better.

Sigh. I don't know why "while(true)" is more common. Probably it's written in some programming books? Yeah, there's no such powerful "for(;;)" in languages other than C/C++, that may be the reason. > > (In reply to comment #61) > > About "m_" for the members in struct: this is a good example that one reviewer > > says this, but another says opposite.

Someone like Eric should have > the last word on that kind of thing, though. It should be struct in this case, because it's used by libjpeg, like a C struct. Probably it should better be wrapped with "extern "C"", although it doesn't really change anything. And at the point, jpeg_dest_mgr is a better name. "pub" acts as the base class of jpeg_dest_mgr. Another idea is: struct JpegDestinationManager: jpeg_destination_mgr { }; What do you think? 138580 65 pkasting 2009-08-09 17:48:55 -0700 (In reply to comment #64) > Making code too much > readable just makes me feel that I'm not doing C++, or I'm doing C++ in MS > style :) I may be sick at the point.

Although he can still do it, but there's no fun. I don't really know what to say. In general style guides aren't designed around what you find fun. But like I said, there's no WebKit style rule on this one. I was giving my personal opinion. If there was a style rule, and you said it wasn't very fun, I don't think it'd earn much sympathy... > Sigh. I don't know why "while(true)" is more common. Probably because "while" was designed for the case when you don't need a loop initializer or increment. > It should be struct in this case, because it's used by libjpeg, like a C > struct. I don't have the contents of libjpeg.h in front of me so it's hard for me to say exactly how something is used, but it looks to me like this struct is entirely your own, set up in compressBitmapToJpeg() and then read in the various helper functions you define. And I can't see how the libjpeg sources could make use of a type defined in your code rather than theirs. From context here it looks like they let you stick some user data on the jpeg_compress_struct they define. In that case, you should define the struct in a way that matches WebKit style. > "pub" acts as the base class of jpeg_dest_mgr. Another idea is: > > struct JpegDestinationManager: jpeg_destination_mgr > { > }; > > What do you think? I think that is not good practice if the libjpeg C code expects to access a jpeg_destination_mgr struct at offset 0 in this object. It probably works, but passing C++ classes with inheritance into C code to use makes me uneasy. 138583 66 yong.li.webkit 2009-08-09 19:05:39 -0700 (In reply to comment #65) > > Probably because "while" was designed for the case when you don't need a loop > initializer or increment. where "for" is designed for all the cases, including the case that no condition check is needed. isn't empty expression better than "true"? :) > > > It should be struct in this case, because it's used by libjpeg, like a C > > struct. > > > "pub" acts as the base class of jpeg_dest_mgr.

It probably works, but > passing C++ classes with inheritance into C code to use makes me uneasy. Using class inheritance can save a reinterpret_cast, and also a weird member "pub". Only thing I should take care is providing a constructor to zero the base class memory.

Uhm, I'm sorry. That came off way harsh... Rather, in the interest of being positive let me just say that after 60+ comments it'd probably be a good idea to refocus on more substantive parts. :) 138595 69 34394 eric 2009-08-09 21:51:17 -0700 Comment on attachment 34394 3) ImageBuffer The ChangeLog really should have more information on what these classes are for, what they do. Why does the WinCE port use this new "SharedBitmap" and what is it for? It seems ImageBufferData is just to allow ImageBuffer to be backed by a SharedBitmap, the question is why? ;) Likewise BufferedImage seems to exist so that Image can be backed by a ImageBufferData. Why wouldn't WinCE have used the BitmapImage abstraction that other classes use? Image exists to abstract between SVGImage, PDFDocumentImage and BitmapImage. Seems you have created a duplicate/parallel BitmapImage-like subclass, no? (Not necessarily giving objection here, just seeking more information!) :) Need more info in the ChangeLog to perform a good review. Also, I think given how comment-full this bug is now, these patches really should be each on their own bugs so they can be discussed where folks have some prayer of being able to read all the relevant comments. :) Indent: +: m_data(size) +, m_size(size) UNUSED_ARG is what you want: + grayScale; // Currently not used c++ casts: + const unsigned char* src = (unsigned char*)m_data.m_bitmap->bytes(); r-, mostly for the lack of ChangeLog information. 138596 70 34401 eric 2009-08-09 21:52:27 -0700 Comment on attachment 34401 8) Color Gradient OK. 138598 71 34398 eric 2009-08-09 21:59:25 -0700 Comment on attachment 34398 6) Path PlatformPath Neat that you wrote your own Path implementation.

I've seen some coding rules (not webkit one) saying "default:" should always present in a switch block, and like this idea. In this case, the compiler won't generate code to compare the value with PathCloseSubpath. Condition checks are expensive on ARM. Probably I should add ASSERT ( ... == PathCloseSubpath); after "default:". Then that looks perfect. 138645 75 eric 2009-08-10 07:41:16 -0700 (In reply to comment #74) > (In reply to comment #71) > > (From update of attachment 34398 [details] [details]) > > Neat that you wrote your own Path implementation.

Condition checks are expensive on ARM. Probably I should add > ASSERT ( ... == PathCloseSubpath); after "default:". Then that looks perfect. Sounds like pre-mature optimization to me. :) The "default:" logic used in WebKit is about trying to catch errors at runtime instead of compile time. I don't think it's a big deal either way. But I don't think optimizing for some one compiler that you've used at one point in your lifetime is ever good plan. This code will be read by many people (hence the style guidelines), compiled by many different compilers and run on many different CPUs before it's removed form the WebKit repository. :) If testing show that this is slow in a certain configuration then we certainly should change it. But before then, I wouldn't worry about the compiler much. Perf testing is likely to show that we have much larger fish to fry. 138646 76 yong.li.webkit 2009-08-10 07:44:35 -0700 (In reply to comment #69) > (From update of attachment 34394 [details]) > The ChangeLog really should have more information on what these classes are > for, what they do.

But platform image type (defined as "NativeImagePtr") is still required. On Windows platform, it can be HBITMAP. SharedBitmap is a replacement of HBITMAP, and is more flexible and useful than HBITMAP. I don't think this basic acknowledge of WebCore should go to ChangeLog.

I'm about as familiar with WebKit Images as you can expect from a reviewer. :) I've worked on the Image stuff several times, including the most recent re-factoring splitting out BitmapImage from Image. Why does WinCE need a NativeImagePtr Image wrapper and other ports don't? I guess other ports use BitmapImage to wrap their NativeImagePtr, no? > If we need more description to help new webkit developers understand webkit > source code, ChangeLog is not a good place to hold it. Agreed. The ChangeLog is about making your change understandable to those reviewing it and later people reading it. If the code itself needs explanation that needs to go in the code. ChangeLogs are in part about making your reviews obviously correct to those reviewing them. Anything that seems non-obvious should be explained in plain english. Non-obvious reviews tend to get r-'d or more likely just ignored until they rot. As others (more famous than I) have noted, ones code is read many more times than it is written, and it's important to make it obviously correct to each of those people reading it. :) This is part of why we have reviews and style guidelines. I think we need to move these into separate bugs given how much parallel discussion is going on. (Small bugs, with small patches is part of trying to make your patches obviously correct for quick review. Once bugs or patches get to a certain size, reviewers tend to ignore them or r- them.) 138648 78 yong.li.webkit 2009-08-10 07:58:10 -0700 (In reply to comment #77) > (In reply to comment #76) > > (In reply to comment #69) > > > (From update of attachment 34394 [details] [details] [details]) > > All ports use BitmapImage class, including WINCE port.

That's how the other ports address this issue. Every other port? What is this? typedef CGImageRef NativeImagePtr; Using smart pointers is definitely an advantage, for example, it can avoid memory leaks (about 1.5 year ago, there was a bug that FrameData leaked. Now it has been fixed. but if all platform NativeImagePtr were reference counted, it wouldn't even be a problem, and "clear(true)" wouldn't necessary in ~FrameData()). Not mentioning that we use SharedBitmap as both decoding buffer and rendering buffer so that no extra memory copying is requried. Generally, I don't think it's a good idea to throw away helpful changes just because we want to be same as other ports. It is supposed to be platform-specific in this case. If we do everything in the same way, why do we need ports? 138735 83 pkasting 2009-08-10 11:12:02 -0700 Please follow Eric's suggestion and split these patches into their own bugs. This is getting unwieldy. (In reply to comment #82) > Every other port?

They're certainly still explicitly releasing it: see the CGImageRelease() call in ImageCG.cpp:FrameData::clear(). But perhaps I am mistaken about what that type is. > Using smart pointers is definitely an advantage, for example, it can avoid > memory leaks (about 1.5 year ago, there was a bug that FrameData leaked.

As noted above, even CG does an explicit release here.

Yes, that is how other ports e.g. CG and Skia work too. For Skia, for example, the setRGBA() call in ImageDecoder.h writes directly to the buffer inside the SkBitmap. > Generally, I don't think it's a good idea to throw away helpful changes just > because we want to be same as other ports. Generally, things that one port does differently from everyone else raise red flags for people trying to read the code. > If we do everything in the same way, why do we > need ports? Because all the ports are built atop cross-platform code. They should only be different where they must, and we're in the process of trying to reduce the differences further. I wasn't saying your code is guaranteed to be wrong. I was saying I'm unable to tell for sure that it's right, whereas if your NativeImage type internally refcounted, and NativeImagePtr was a raw pointer, I wouldn't even have to worry, because the idiom is the same. All I'd need to check is that you allocated and freed in the right places. The strength of copying other ports is that we can review your code and guarantee it's correct, and others can read and understand what you're doing. It's the same reason we have style guides. 138827 84 yong.li.webkit 2009-08-10 14:47:11 -0700 (In reply to comment #69) > (From update of attachment 34394 [details]) > The ChangeLog really should have more information on what these classes are > for, what they do.

Sorry, I misunderstood your question. Yes, BufferedImage is parallel to BitmapImage. The reason we use BufferedImage is that BitmapImage is too expensive in this case. Another option is to implement BitmapImage(NativeImagePtr, ImageObserver* = 0) as other ports do. ImageBuffer::image() is supposed to return an Image interface which is used only for render. BufferedImage is very thin, and I think it makes things much simpler than doing it in another way. 138848 85 34396 staikos 2009-08-10 15:54:30 -0700 Comment on attachment 34396 5) MediaPlayer > diff --git a/WebCore/ChangeLog b/WebCore/ChangeLog > index 3afc825..2facda8 100644 > --- a/WebCore/ChangeLog > +++ b/WebCore/ChangeLog > @@ -1,3 +1,16 @@ > +2009-08-08 Yong Li <yong.li@torchmobile.com> > + > + Reviewed by NOBODY (OOPS!). > + > + WINCE PORT: MediaPlayerProxy and MediaPlayerPrivate > + https://bugs.webkit.org/show_bug.cgi?id=27511 > + > + Written by Crystal Zhang <crystal.zhang@torchmobile.com> > + > + * platform/graphics/wince/MediaPlayerPrivateWince.h: Added. > + * platform/graphics/wince/MediaPlayerProxy.cpp: Added. > + * platform/graphics/wince/MediaPlayerProxy.h: Added.

If I understand you correctly, I think you're saying that you think the WebKit coding style requires removing these braces. That's wrong. The WebKit coding style says braces should be omitted from one-line bodies, and this is more than one line. Perhaps you were thinking it said to omit them from one-statement bodies? The braces should stay. 138850 87 staikos 2009-08-10 16:01:02 -0700 (In reply to comment #86) > > > + NamedNodeMap* a = element->attributes(); > > > + if (a) { > > > + for (unsigned i = 0; i < a->length(); ++i) { > > > + Attribute* it = a->attributeItem(i); > > > + paramNames.append(it->name().localName().string()); > > > + paramValues.append(it->value().string()); > > > + } > > > + } > > > > I guess you should remove the braces around the if, as ugly as it becomes. > > If I understand you correctly, I think you're saying that you think the WebKit > coding style requires removing these braces. > > That's wrong.

Yes, and it doesn't strictly fit into the "braces" example by my read, but I know what you're implying.
