security/sandbox/chromium/sandbox/win/src/broker_services.cc is a sandbox code from upstream. We should update it from upstream rather than patching here.

(We can change files under ipc/chromium because we already gave up to sync them from upstream.)

r+ with the change to modifications-to-chromium-to-reapply-after-upstream-merge.txt and maybe the comment update.

Right, but as far as I can tell that's effectively what Chris's patch does.

::: ipc/chromium/src/base/process_util_win.cc:280
(Diff revision 1)
>    // where only specified handles are inherited - so we use this technique if
>    // we can.  If that technique isn't available (or it fails), we just don't
> -  // inherit anything.  This can cause us a problem for Windows XP testing,
> +  // inherit anything.

nit: given in theory it is always available now, maybe end with:

  // where only specified handles are inherited - so we use this technique.
  // If that fails we just don't inherit anything.

::: security/sandbox/chromium/sandbox/win/src/broker_services.cc
(Diff revision 1)
>        startup_info.startup_info()->hStdError = stderr_handle;
>        // Allowing inheritance of handles is only secure now that we
>        // have limited which handles will be inherited.
>        inherit_handles = true;
>      }
> -  } else if (getenv("MOZ_WIN_INHERIT_STD_HANDLES_PRE_VISTA")) {

Please remove the bug1287426part4.patch line from security/sandbox/modifications-to-chromium-to-reapply-after-upstream-merge.txt as well.

Thanks! I'll update the comments and patch file before landing.

Yes. My patch is just reverting some of our downstream modifications of Chromium's sandbox code.
