Hello fellows, i spent quite a while banging my head trying to understand why a luci graph was not working, the XHR.poll() was failing on a given, specific URL. turns out, it failed when the url ended like "whatever_adhoc" luci XHR appends a '?_=0.15089513623292194', resulting in a url like http://10.5.0.6/cgi-bin/luci/.../wlan0_adhoc?_=0.15089513623292194 after a quick chat with jow, i found out it was uBlock getting in the way; chromium with adBlockPlus gave the same problem. i have both with defaults settings, namely, just use Easylist see it for yourselves: https://easylist-downloads.adblockplus.org/easylist.txt includes the expression _adhoc? the "?" is not a regexp, it's a literal "?", but as i said XHR.poll appends a '?' to the end of the url, completing the blocked expression so this breaks, for example, luci Realtime Traffic graphs for the interface "wlan0_adhoc", amongst others. My suggestion for this bizarre coincidence of events, is simply to change our lime separator to "-" instead of "_" which, by the way, is more "in line" with upstream automatic names for several wifi-ifaces are like wlan0, wlan0-1, wlan0-2 so it's better if we use wlan0-adhoc, wlan0-ap, etc and for the vlanSeparator (which is currently '-') just use '_', so complete interface name will be wlan0-adhoc_167 and such (exactly the opposite of the current name, but at least to me it makes more sense, and as a bonus this will not end up in a blocked url) cheers!
