You'd probably want an API that lets the embedding app request a particular icon size, and picks the best fit from the icon links available, taking into account size=any as well. Possible niceties - return windows-style .ico or mac-style .icns either if explicitly specified, or synthesized from available sizes. Not sure if there is a conventional multisize icon format on other platforms.

We investigating in multithreading possibilities. In connection with the GC I try to organize the mark phase into a parallel thread. The idea is to have 2 heap, serve allocations from the active one, while marking the other. When the active is full, swap them.

[webkit-dev] MD5 in WebCore
I'm implementing new protocol of WebSocket (
http://www.whatwg.org/specs/web-socket-protocol/ ).
Since it now requires MD5 in handshake, I wonder how I could add MD5 in
WebCore. For now, there is no MD5 in WebCore. It is in
WebKitTools/DumpRenderTree to get message digest of image file.
I'm thinking to add new header file as WebCore/platform/MD5.h, which
provides the following functions.
struct MD5_CTX;
void MD5_Init(MD5_CTX*);
void MD5_Update(MD5_CTX*, unsigned char* input, unsigned length);
void MD5_Final(unsigned char hash[16], MD5_CTX*);
In Windows platform, it is implemented using Cryptdll.dll. Is it ok to
copy WebKitTools/DumpRenderTree/win/MD5.cpp to WebCore/platform/win/MD5.cpp,
or move?
In Mac platform, it is provided by CommonCrypto/CommonDigest.h with
#define COMMON_DIGEST_FOR_OPENSSL ?
In Chromium, there is chrome/src/base/md5.{h,cc}. Should I copy this in
WebCore/platform/chromium, or add dependency to base from WebCore?
How about other ports? is it ok to link openssl or some other library? (or
use implementation used in chromium?)
I'm also wonder I need to put these functions in namespace WebCore.

If you put this code in WebCore, it should go in the WebCore
namespace. I think it would also be a good idea to turn the API into
something more WebCore-ish, something like:
namespace WebCore {
class MD5 {
MD5(); // what was MD5_Init
addBytes(uint8_t* input, size_t length); // what was
MD5_Update ; or maybe this should take a Vectoruint8_t?
Vectoruint8_t, 16 checksum(); // what was MD5_Final
};
}
(The key point being to match the coding style guidelines for names,
but it also seems better to use a class here instead of a struct and
functions that take a pointer to it.)

In Chromium, we use ImageSource instead of BitmapImage for this, because ImageSource already has public functions for everything you want (e.g. frameCount(), frameSizeAtIndex(), etc.), and thus no changes are needed. When we have some data blob that represents the favicon and we need to pick a good image (size) out of it, we just instantiate an ImageSource directly.

Since it now requires MD5 in handshake, I wonder how I could add MD5 in
WebCore. For now, there is no MD5 in WebCore. It is in
WebKitTools/DumpRenderTree to get message digest of image file.
I'm thinking to add new header file as WebCore/platform/MD5.h, which
provides the following functions.
struct MD5_CTX;
void MD5_Init(MD5_CTX*);
void MD5_Update(MD5_CTX*, unsigned char* input, unsigned length);
void MD5_Final(unsigned char hash[16], MD5_CTX*);
In Windows platform, it is implemented using Cryptdll.dll. Is it ok to
copy WebKitTools/DumpRenderTree/win/MD5.cpp to WebCore/platform/win/MD5.cpp,
or move?
In Mac platform, it is provided by CommonCrypto/CommonDigest.h with
#define COMMON_DIGEST_FOR_OPENSSL ?
In Chromium, there is chrome/src/base/md5.{h,cc}. Should I copy this in
WebCore/platform/chromium, or add dependency to base from WebCore?
How about other ports? is it ok to link openssl or some other library?
(or use implementation used in chromium?)
I'm also wonder I need to put these functions in namespace WebCore.
If you put this code in WebCore, it should go in the WebCore namespace. I
think it would also be a good idea to turn the API into something more
WebCore-ish, something like:
namespace WebCore {
class MD5 {
MD5(); // what was MD5_Init
addBytes(uint8_t* input, size_t length); // what was MD5_Update ;
or maybe this should take a Vectoruint8_t?
Vectoruint8_t, 16 checksum(); // what was MD5_Final
};
}
(The key point being to match the coding style guidelines for names, but
it also seems better to use a class here instead of a struct and functions
that take a pointer to it.)

I'd rather use a platform-independent MD5 implementation in WebCore if
possible.
Since the MD5 code itself has (presumably) minimal dependencies,
perhaps we could put it in WTF. I don't know if that would help
Chromium's dependency issues.

In the case of WebSocket protocol, the hash doesn't need to be
cryptographically secure. Forging the hash is not a consideration. To
give a rough outline, the hash is used like this:
1) The browser sends a few pieces of information to the server
(including the Origin, a string specifically identifying the WebSocket
protocol, etc).
2) The server combines some of this info and computes a hash.
3) The hash is returned to the client, which verifies it.
Steps 2 and 3 are the ones that use MD5. The reason for this handshake
is to defend against cross-protocol attacks. The server responds with
information based on unique parts of the request, to avoid the
likelihood that a response from a non-WebSocket server won't
accidentally look like a valid handshake. A hash is used to reduce the
risk that a server that just echoes back pieces of the response may
look like a valid handshake respnse.
I don't believe a cryptographically secure hash is needed here, it
could have been something as simple as CRC-32, for example. I think
the reason to pick MD5 was that it's well known and widely available
as a library for many popular programming languages.
