Small bug fix at WebRequest.cpp
There was a problem hiding this comment.
I agree: this looks like a bug. "__is_param_char" macro expansion will cause multiple increments of i++. That is a dangerous macro. Rather than a macro, perhaps we should be using a function here?
bool is_param_char(char c) {
return
(c != 0) &&
(c != '{') &&
(c != '[') &&
(c != '&') &&
(c != '=');
}
From reading your code, it should also work around the bug, but I can't test it.
Edit: explicitly test c for null (c!=0) instead of (c).

Yes, I also think is best to replace the macro with a function. |
