From: Eli Zaretskii <eliz <at> gnu.org> To: 12230 <at> debbugs.gnu.org Subject: bug#12230: 24.2; revert-buffer in an Info buffer should refresh Info-index-nodes Date: Sat, 18 Aug 2012 21:15:24 +0300
This problem cannot easily happen in "emacs -Q", so no reproducible recipe, sorry. However, the problem is quite clear: if you "M-x revert-buffer" in an Info buffer, and the new Info file changed the names of its Index nodes, then the 'i' command will most probably fail the next time you invoke it in that Info buffer. A case in point is the GDB manual: it recently split its Index node into 2 nodes, called "Concept Index" and "Command and Variable Index", respectively. After reverting its Info buffer, 'i' started signaling an error, complaining about the missing node "Index". The problem is that info.el caches the Index nodes in the alist stored in Info-index-nodes. It should therefore remove from that alist the association of the Info file whose buffer is reverted.
