Looking at AIX 5, there is no termcap file, the manpage for terminfo does not mention the names used for the second parameter, and "strings" on the curses library shows no plausible tables containing those strings.

There's a manpage for tgetstr, which states that it is used for applications which use the termcap file. However, tgetstr is implemented in the curses library, which does not use termcap. (I did ports to AIX 3 and 4 a while back, and from that and notes am reasonably aware of their issues - it's been quite a while since someone defended AIX 4 as being current - perhaps ten years). > > and "strings" on the curses library shows no plausible tables > > containing those strings. > > The termcap translation table can be arbitrarily encoded. libncurses > doesn't contain those literal strings either. If it's not in the AIX curses library, it won't be recognized by that implementation - it relies upon a table, not upon an external user-supplied definition of any kind whatsoever. ncurses uses a different method, not used by any of the vendor unixes. Furthermore, there is no point in bringing extensions which could be defined by a user for ncurses into a topic which deals with "IBM terminfo". -- Thomas E.

There are several things to discuss: + this thread started in Debian #698299 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698299 + the original report cited a few urls, including a previous thread for Emacs: http://stackoverflow.com/questions/10871745/shift-up-arrow-doesnt-highlight-text-emacs-iterm2 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-05/msg00211.html http://forums.vandyke.com/showpost.php?p=26580&postcount=25 + Sven commented that removing the line with "kU" fixed the reported problem. + I commented that the mailing-list thread discussing this had quoted a comment from the Emacs source code indicating that the chunk of code had been written for a "non-standard dialect of terminfo". I'd read that thread before, noting (to myself) only that the comment was incorrect since the mnemonics in quotes are all termcap. The first parameter (F1, F2, %1) is a conventional termcap name (there are no standards for termcap - it owes its existing convention to documentation in the terminfo manual), while the others were unfamiliar to me. You can see the names in terminfo(5). + however, as a bug report against ncurses I pay more attention. The problem is to infer where the problem is, and possible causes. + Emacs uses the termcap interface provided by ncurses, which means that Emacs calls tgetstr, tgetnum, tgetflag to obtain string, numeric, boolean values. The termcap interface matches only the first 2 characters of capability names. (The reason for not requiring that the names have a trailing null, I seem to recall being for compatibility with termcap libraries which do this, leading to applications that rely upon the behavior). + this behavior was commented on in a different thread: http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00012.html + tgetstr looks for each name, starting with the predefined termcap names, and then the extended names - unless one calls the ncurses function use_extended_names(FALSE); That's been the behavior since 1999. The current data for the extended keys for xterm dates from April 2005. + uses for the above features (and quirks) are long established. That leads to considering how the problem arises in Emacs, and whether Emacs needs the problematic code. + The thread from October suggests that the problem is that Emacs is calling tgetstr with "kU" as a parameter. That will return data for kUP (an extended key). Schwab comments that kR is the same as kri - though there's a pitfall there. Quoting from terminfo(5): key_sf kind kF scroll-forward key key_sr kri kR scroll-backward key key_sleft kLFT #4 shifted left-arrow key key_sright kRIT %i shifted right-arrow key You may notice that terminfo(5) does not define a shifted up or down-arrow. (Whether kind and kri should fill that role is arguable - I decided they would, and in October 2005 modified xterm-new to provided that connection but have found no prior art to establish that connection in usage by others). I retained kUP because it fits a pattern of names for extended keys. So... if Emacs looks for "kU" and gets "kUP" data, and then sees that it is the same string as an existing key kR, then it could conclude that the assignment for "kU" was ineffective and that "select" is not defined. + Emacs could of course solve the problem by calling use_extended_names(FALSE); I recall making that suggestion to someone working on Emacs a few years ago - that's apparently not been done. + Alternatively (as suggested in the threads mentioned), one could remove the problematic call from Emacs. That could be done if it serves no useful purpose. From discussion and examining the source code, it appears that the "non-standard terminfo" cited in the comment is unlikely to be in use by anyone some 18 years later - it dates from 1994-10-14. AIX 4 was released in 1994; the code was for AIX 4 (early) or AIX 3 (late). In either case it's old. AIX 5 is more than ten years old. The entire chunk relating to that comment could be removed. There is other obsolete code in term.c, e.g., the Teleray code, the Hazeltine code, not to mention Emacs insistence on using termcap names on a terminfo system :-) + Schwab's comments this morning seemed to be focused on retaining the code because (a) it was related to terminfo and (b) ncurses uses terminfo. My viewpoint on it is that the code is useful only if there is a system whose users rely upon it, that a tie to ncurses is pointless. The data in ncurses exposes some code which is no longer useful. > >>>>> "dickey" == dickey <dickey@his.com> writes: > > > On Thursday, January 17, 2013 3:53:15 AM UTC-5, Sven Joachim wrote: > >> --8<---------------cut here---------------start------------->8--- > >> === modified file 'src/term.c' > >> --- src/term.c 2013-01-11 02:40:58 +0000 > >> +++ src/term.c 2013-01-17 08:49:20 +0000 > >> @@ -1415,7 +1415,6 @@ term_get_fkeys_1 (void) > >> CONDITIONAL_REASSIGN ("F1", "k<", "f11"); > >> CONDITIONAL_REASSIGN ("F2", "k>", "f12"); > >> CONDITIONAL_REASSIGN ("%1", "kq", "help"); > >> - CONDITIONAL_REASSIGN ("*6", "kU", "select"); > >> > >> #undef CONDITIONAL_REASSIGN > >> > >> } > > > A follow message says that there is a comment > > > /* IBM has their own non-standard dialect of terminfo. > > If the standard name isn't found, try the IBM name. */ > > > which is interesting: the code fragment is dealing with termcap > > names (the first parameter is conventional termcap names, the > > second is not).

AFAIK this is not a regression, and it's far from an obviously-safe fix, so I don't think it qualifies for emacs-24. Stefan ^ permalink raw reply [flat|nested] 20+ messages in thread

I had already resolved yesterday what changes I would make to ncurses. That involved some more research to document the issue properly. And some code change, as needed. Since you are not in a hurry, it will percolate along. Incidentally, I checked my archives, and determined that the bogus code in Emacs did not reflect AIX 4. Even AIX 3 is questionable (1992), since that feature did not appear in AIX 3's termcap file. It may have been a customization on someone's personal system, but did not appear in the IBM product within the past 20 years. -- Thomas E.

Rather than moving the cursor and selecting text, Emacs beeps and informs you: <select> is undefined. This seems to have been discussed a few times, e.g. in the threads starting at http://lists.gnu.org/archive/html/help-gnu-emacs/2011-05/msg00174.html http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00267.html The latter thread mentions in http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00290.html that the following change --8<---------------cut here---------------start------------->8--- === modified file 'src/term.c' --- src/term.c 2013-01-11 02:40:58 +0000 +++ src/term.c 2013-01-17 08:49:20 +0000 @@ -1415,7 +1415,6 @@ term_get_fkeys_1 (void) CONDITIONAL_REASSIGN ("F1", "k<", "f11"); CONDITIONAL_REASSIGN ("F2", "k>", "f12"); CONDITIONAL_REASSIGN ("%1", "kq", "help"); - CONDITIONAL_REASSIGN ("*6", "kU", "select"); #undef CONDITIONAL_REASSIGN } --8<---------------cut here---------------end--------------->8--- would fix that; I can confirm that, but don't know if it might break anything.
