Comment on attachment 695261 [details] [diff] [review] patch > nsresult nsMsgFilterList::GetFilterAt(uint32_t filterIndex, nsIMsgFilter **filter) > { > NS_ENSURE_ARG_POINTER(filter); >- >- uint32_t filterCount = 0; >- GetFilterCount(&filterCount); >- NS_ENSURE_ARG_MAX(filterIndex, filterCount - 1); >+ NS_ENSURE_ARG(filterIndex < m_filters.Length()); You're trying to fix too many bugs at once and ending up with a mishmash. Although it's a good idea to replace calls to GetFilterCount with direct access to Length() you should file a separate bugs and fix up all the cases at once. Please put this back for now so that it looks like the check in MoveFilterAt below. r=me with that fixed.

I do not want to replace any other occurrence of GetFilterCount in that file. If you see the file history I am the one who put them there originally ;) I just wanted to replace this single one. So I will not file any separate bug for that. So if you consider the change to be good as you say, either accept it here, or I take it out as you wish, but then it will not be done later (at least not by me).

When I said "calls" I meant "all the internal calls". I didn't mean "one call because I felt like it". I can't see any justification for only changing one call.

As you wish.
