544440 - IPDL: Remove support for possibly platform-dependent-sized types

Status: RESOLVED WONTFIX

(Core :: IPC, defect)

Description

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

Needs to be done for loading 32-bit plugins in subprocesses of 64-bit firefox, and better sooner rather than later.

I think these are the possibly offending types.

    'int',
    'long',
    'intptr_t',
    'uintptr_t',
    'size_t',
    'ssize_t',
    'PRBool',
    'PRSize',

There are core windows types (HANDLE) which are different sizes, IIRC. We could remove support for these, or we could force them to be serialized at a fixed size using traits.

PRBool is fixed-size, FWIW. What about `bool`?

OK.  AFAIK 'bool' isn't necessarily fixed size; I had intended to put it on the list.  Thanks for pointing out the omission.

We have a reasonable scheme for this now.
