You'd better also update fast/files/workers/read-*-async-expected.txt though worker tests are skipped now.

Where did you get the message?

Probably it is simpler to name it as ErrorCode as in PositionError.h or GeolocationError.h.

> WebCore/fileapi/FileException.h:65
> +    static int FileErrorCodeToExceptionCode(int fileErrorCode)

Probably simpler to call it as ErrorCodeToExceptionCode.

Done.

Basically I copy-pasted those messages from the spec (plus some minor modifications to make them look alike).
For this particular one it's from FileSystem spec, 7.3 Error Code Descriptions.
http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#error-code-descriptions
Please feel free to correct the sentences if they look weird or not relevant.

Fixed.

>> WebCore/fileapi/FileException.h:65
>> +    static int FileErrorCodeToExceptionCode(int fileErrorCode)

Fixed.

This description text seems to be too specific.

Do you have any alternative suggestions?

It's the only case where useragent should fire SYNTAX_ERR in the entire File API spec and I don't see the strong reason to change it now.

Though it is only used in one particular case, I am afraid that it might be used in other cases without updating the original description. How about something like:
  "Invalid or unsupported argument, like invalid line ending specifier."
