like google3, we don't use streams. Please use StringAppendF() instead.

[mtomasz, 2012/10/12 11:09:46]

Done.

assignment in while() looks a bit tricky. maybe just a matter of taste, but the
following may be good?

while (true) {
  const HttpRequestParser::STATE parser_state = request_parser_.ParseRequest();
  if (parser_state != READY)
    return parser_state != SYNTAX_ERROR;
  ...
}
NOTREACHED();
return false;

[mtomasz, 2012/10/12 11:09:46]

I know that this while is non-trivial, but personally while (true) with
NOTREACHED() is more tricky for me...

[satorux1, 2012/10/16 03:12:18]

Then that's fine.

+      HttpRequestParser::READY) {

[satorux1, 2012/10/12 08:29:18]

indentation is off? should look like:

while ((parser_state = request_parser_.ParseRequest()) ==
       HttpRequestParser::READY) {

[mtomasz, 2012/10/12 11:09:46]

Here I made a 4-spaces indentation as for too long line. Do we have any rule
when do 4-spaces, and when to align?

[satorux1, 2012/10/16 03:12:18]

In conditionals, we should align vertically.

[satorux1, 2012/10/16 03:19:25]

Not only in conditionals, if stuff in parens is longer than one line, we should
align vertically like:


SomeLooooooooooooooooooooooooooongNameFunction(12345,
                                               67890);

or 

SomeLooooooooooooooooooooooooooongNameFunction(
    12345, 67890);

+      return false;
+    }
+  }
+  // If syntax error occured, then we drop the connection.
+  return parser_state != HttpRequestParser::SYNTAX_ERROR;
+}

+}  // namespace gdata
