</blockquote></span></div><div class="gmail_extra"><br></div><div class="gmail_extra">You can more or less ignore that point.</div><br>The intent is to alert those who update the static bindings (i.e. Apple LLDB team) that the bindings generated and post processed from swig are not matching the static ones. This would just get sent to an internal group over here since I'm not hearing definite resistance to moving to a static-by-default model. (If we had gone static-by-default, and made it clean and explicit when modifying the SB API surface area by requiring an update-the-binding step, there would have been no way to test the bindings without having done the "update the bindings" step. Since we won't be doing that, then I need some way to ensure I know bindings are stale).</div><div class="gmail_extra"><br></div><div class="gmail_extra">That's really a detail you won't need to worry about, though, since you will not be using static bindings ever, and won't have to address any time they go stale. The fact that it happens on a public builder is not very interesting either. I worded it in a way that made it sound like others externally would see the staleness alert, but that's not what I meant.</div><div class="gmail_extra"><br></div><div class="gmail_extra">(I may automate that later, but not until I make sure it works manually up front).<span class="HOEnZb"><font color="#888888"><br>-- <br><div><div dir="ltr">-Todd</div></div>
