Proposed Patch

WebCore/html/Blob.cpp:93
 +          static_cast<const File*>(this)->captureSnapshot(size, modificationTime);
nit: add a FIXME about eliminating this synchronous file operation perhaps?

WebCore/html/Blob.h:66
 +      virtual unsigned long long size() const { return static_cast<long long>(m_size); }
nit: looks like this static_cast shouldn't be necessary since m_size is type "long long"

WebCore/html/BlobBuilder.cpp:88
 +          file->captureSnapshot(snapshotSize, snapshotModificationTime);
same comment about snapshotting asynchronously one day.

WebCore/html/File.cpp:74
 +      // come up with an exception to throw if file size is not represetable.
represetable -> representable

WebCore/html/File.cpp:86
 +      if (!getFileSize(m_path, snapshotSize) || !getFileModificationTime(m_path, modificationTime)) {
it would be nice to combine these into a single file system call.  that way in
chromium, it will be only a single synchronous IPC.  this can be deferred to
another patch of course.

WebCore/html/File.h:69
 +      void captureSnapshot(long long& snapshotSize, double& snapshotModificationTime) const;
please put a warning comment about the fact that this does a synchronous file operation.
we want people to think twice before calling this function.

WebCore/html/FormDataList.h:56
 +      class Item {
nit: nicer to put inner class definitions at the top of the public section?

WebCore/platform/network/FormData.cpp:143
 +               break;
indentation

WebCore/platform/network/FormData.cpp:222
 +                      name = name.replace("-", ""); // For safty, remove '-' from the filename snce some servers may not like it.
snce -> since

those are just nits, so R=me

safty -> safety
as well.
