            Bug ID: 144263
           Summary: Streaming bytes of source code to SHA1 to calculate
                    CodeBlockHash
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: utatane.tea at gmail.com

Currently, CodeBlockHash once converts the entire source code string to the UTF-8 string and pass it to SHA1 to calculate the hash value.
However, it's memory consuming because this process allocates a large buffer to store the entire UTF-8 string.
Instead of the current process (alloc, convert, and use), we should implement the streaming decoder decoding UTF-16 into UTF-8 and stream the bytes into SHA1 iteratively.
