Actually, this probably belongs more at the bottom of
chrome/installer/util/util_constants.cc

And please use char[] instead of char*.

---------------------

Actually, another comment below makes the need for one of these hardcoded string
go away, so that you can inline this back where it belongs in
browser_distribution.cc without even needing a global constant :).

comment on comment: my gut tells me that static initializers should come before
the ctors at the top of the implementation, not at the end of the file.

for all functions like this, make the NOTREACHED case do something sensible.
it's better to return some wrong value in a release build than to return a
nonsensical value. my suggestion here is:
  switch (shortcut_type) {
    case SHORTCUT_ALTERNATE_CHROME:
      // TODO(calamity): Change IDS_OEM_MAIN_SHORTCUT_NAME in
      // chromium_strings.grd to "The Internet" (so that it doesn't collide with
      // the value in google_chrome_strings.grd) then change this to
      // installer::GetLocalizedString(IDS_OEM_MAIN_SHORTCUT_NAME_BASE)
      return L"The Internet";
    case SHORTCUT_APP_LAUNCHER:
      return installer::GetLocalizedString(IDS_APP_LIST_SHORTCUT_NAME_BASE);
    default:
      DCHECK_EQ(shortcut_type, SHORTCUT_CHROME);
      return GetBaseAppName();
  }

you'll also need to add IDS_APP_LIST_SHORTCUT_NAME to kStringIds in
chrome/installer/util/prebuild/create_string_rc.py.

[calamity, 2013/07/16 04:05:17]

Done. Any reason to use DCHECK_EQ instead of NOTREACHED()?

[grt (UTC plus 2), 2013/07/16 19:38:44]

DCHECK_EQ will show the value that shouldn't have happened in the log. Also, I'm
not sure how you'd structure the code to use NOTREACHED without having any
duplicate code. I suppose you could have case SHORTCUT_CHROME: break; default:
NOTREACHED(); break; } return GetBaseAppName(), but I find my suggested
structure more concise and clear.

how do icons work for Chromium builds?

[calamity, 2013/07/16 04:05:17]

I'm not sure. Does anybody else know?

[grt (UTC plus 2), 2013/07/16 19:38:44]

I just installed Chromium r211796, and the uninstall link in the Programs and
Features control panel is missing its icon because of this. I wonder how long
it's been broken. Please change this to return installer::kChromeExe and add
issue 161985 to the list of those fixed by this CL.
