55203 - xpidl should warn on out-of-range constant

Status: RESOLVED WONTFIX

(Core :: XPCOM, enhancement, P3)

Description

[Michael Ang]

If you specify a constant that is too large for its storage type, then you will
get a pseudo-random value in your header file and typelib.

e.g.
  const long qux = 233232132132131321123213;
  const long quux = -121212121212212121212121;

Get you -1 and 0 respectively.

I'm not actually suggesting we burn cycles to fix this given that it probably
won't come up in practice.  Just want to mark this for posterity.

I think this is a libIDL issue.  Andrew?

Comment 2

[Hixie (not reading bugmail)]

WONTFIX?

Comment 3

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

WONTFIX, unless we rewrite atop a different IDL parser (which is sometimes
tempting, I confess!).
