The problem can be reproduced easily. Emacs seems to have an terminal issue when being back from background mode on shell. Let me explain: When I put emacs in background (^z) and then in foreground again ("fg", bash) sometime emacs will not reset properly the terminal and I won't be able to scroll up (using PageUp/PageDown). After debugging the issue with a tmux developer, we tracked it down to emacs and believe this is an emacs issue with terminal handling when going back from background mode. I am attaching a snippet of the technical detail about this issue : > When you ^Z, tmux gets 112 bytes in all cases: > > input_parse: %0 ground, 40 bytes: \n\n\033[K\033[?1l\033>\033[34h\033[?25h\033[?1049l\033[39;49m\r > input_parse: %0 ground, 72 bytes: \r\n[1]+ Stopped emacs large_text_file.txt\r\nroot@milu:~# > > \033[?1049l is rmcup which exits cursor positioning (alternate screen) mode. > > Then when you type fg, it gets: > > input_parse: %0 ground, 694 bytes: \033[?1049h\033[34l\033[?1h\033=\033[24;1H\033[K\033[H\033[?25l\033[3mFile Edit Options Buffers ... > > \033[?1049h is smcup which turns it on again. > > But sometimes, it gets: > > input_parse: %0 ground, 674 bytes: \033[24;1H\033[K\033[H\033[?25l\033[3mFile Edit Options Buffers ... > > Where emacs is not sending \033[1049h, or in fact any of the smcup, > cvvis, smkx sequence it normally sends. This can be reproduced by hitting ^z and then "fg" in a loop for a couples of minutes. If you run tmux with "tmux -vvvv" you will be able to obtain the logs mentionned above. To observe the problem you can just press PageUp each time you are back in emacs, when the bug will reproduce you won't pageUp inside emacs but enter the tmux's copy-mode. My ~/.tmux.conf only has 1 line: bind-key -T root PPage if-shell -F "#{alternate_on}" "send-keys PPage" "copy-mode -e -u" If you need me to apply some patch and/or reproduce just let me know I will happily helps.

Probably because Emacs tries to optimize the cursor motion commands for minimal cost. See the code of the cmgoto function (in cm.c in Emacs sources). But you didn't tell what terminfo entry is used by Emacs on your system, and didn't tell what the above terminal commands do on your terminal, so it's hard to proceed in investigating this issue. Thanks.

So I did another patch and another try. I can still reproduce the bug. Any more advices on stuff I should try are welcomed ;-) Here is the patch: --- emacs24-24.4+1.orig/src/cm.c 2014-10-21 23:45:42.000000000 +0200 +++ /dev/shm/cm.c 2016-08-03 15:10:55.803193217 +0200 @@ -327,10 +327,12 @@ char *p; const char *dcm; +#if 0 /* First the degenerate case */ if (row == curY (tty) && col == curX (tty)) /* already there */ return; - +#endif // XXX MODEM + if (curY (tty) >= 0 && curX (tty) >= 0) { /* We may have quick ways to go to the upper-left, bottom-left, @@ -375,7 +377,7 @@ * In the following comparison, the = in <= is because when the costs * are the same, it looks nicer (I think) to move directly there. */ - if (directcost <= relcost) + if (directcost <= relcost || 1) // XXX MODEM { /* compute REAL direct cost */ cost = 0; @@ -383,14 +385,14 @@ ? tgoto (dcm, row, col) : tgoto (dcm, col, row)); emacs_tputs (tty, p, 1, evalcost); - if (cost <= relcost) + if (cost <= relcost || 1) // XXX MODEM { /* really is cheaper */ emacs_tputs (tty, p, 1, cmputc); curY (tty) = row, curX (tty) = col; return; } } - + switch (use) { case USEHOME: --------------090709070509030101060602 Content-Type: text/x-patch; name="second_try.patch" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="second_try.patch" --- emacs24-24.4+1.orig/src/cm.c 2014-10-21 23:45:42.000000000 +0200 +++ /dev/shm/cm.c 2016-08-03 15:10:55.803193217 +0200 @@ -327,10 +327,12 @@ char *p; const char *dcm; +#if 0 /* First the degenerate case */ if (row == curY (tty) && col == curX (tty)) /* already there */ return; - +#endif // XXX MODEM + if (curY (tty) >= 0 && curX (tty) >= 0) { /* We may have quick ways to go to the upper-left, bottom-left, @@ -375,7 +377,7 @@ * In the following comparison, the = in <= is because when the costs * are the same, it looks nicer (I think) to move directly there. */ - if (directcost <= relcost) + if (directcost <= relcost || 1) // XXX MODEM { /* compute REAL direct cost */ cost = 0; @@ -383,14 +385,14 @@ ? tgoto (dcm, row, col) : tgoto (dcm, col, row)); emacs_tputs (tty, p, 1, evalcost); - if (cost <= relcost) + if (cost <= relcost || 1) // XXX MODEM { /* really is cheaper */ emacs_tputs (tty, p, 1, cmputc); curY (tty) = row, curX (tty) = col; return; } } - + switch (use) { case USEHOME: --------------090709070509030101060602-- From debbugs-submit-bounces@debbugs.gnu.org Thu Aug 04 13:07:49 2016 Received: (at 24124) by debbugs.gnu.org; 4 Aug 2016 17:07:50 +0000 Received: from localhost ([127.0.0.1]:55840 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1bVM7Z-0006dA-Nu for submit@debbugs.gnu.org; Thu, 04 Aug 2016 13:07:49 -0400 Received: from eggs.gnu.org ([208.118.235.92]:41708) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1bVM7X-0006cx-RN for 24124@debbugs.gnu.org; Thu, 04 Aug 2016 13:07:48 -0400 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1bVM7P-0001VJ-57 for 24124@debbugs.gnu.org; Thu, 04 Aug 2016 13:07:42 -0400 X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on eggs.gnu.org X-Spam-Level: X-Spam-Status: No, score=-0.4 required=5.0 tests=BAYES_50,RP_MATCHES_RCVD autolearn=disabled version=3.3.2 Received: from fencepost.gnu.org ([2001:4830:134:3::e]:37698) by eggs.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1bVM7P-0001V8-1q; Thu, 04 Aug 2016 13:07:39 -0400 Received: from 84.94.185.246.cable.012.net.il ([84.94.185.246]:4265 helo=home-c4e4a596f7) by fencepost.gnu.org with esmtpsa (TLS1.2:RSA_AES_128_CBC_SHA1:128) (Exim 4.82) (envelope-from ) id 1bVM7L-0004qw-M3; Thu, 04 Aug 2016 13:07:37 -0400 Date: Thu, 04 Aug 2016 20:07:16 +0300 Message-Id: <83shuklayj.fsf@gnu.org> From: Eli Zaretskii To: modem In-reply-to: <57A1EFD4.2060100@member.fsf.org> (message from modem on Wed, 3 Aug 2016 15:21:24 +0200) Subject: Re: bug#24124: emacs terminal escape command error References: <579F5E03.70201@member.fsf.org> <57A1EFD4.2060100@member.fsf.org> MIME-version: 1.0 Content-type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.2.x-3.x [generic] X-Received-From: 2001:4830:134:3::e X-Spam-Score: -6.3 (------) X-Debbugs-Envelope-To: 24124 Cc: 24124@debbugs.gnu.org X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: Eli Zaretskii Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -6.3 (------) > From: modem > Date: Wed, 3 Aug 2016 15:21:24 +0200 > > > I think you disabled the wrong code.

It could be some problem with some other piece of software, not with Emacs. Is there someone you could ask to produce a human-readable description of the command Emacs sent to the terminal driver, both in the "good" and in the "bad" cases? I mean this citation which you brought originally, but without any details: > I am attaching a snippet of the technical detail about this issue : > > > When you ^Z, tmux gets 112 bytes in all cases: > > > > input_parse: %0 ground, 40 bytes: > \n\n\033[K\033[?1l\033>\033[34h\033[?25h\033[?1049l\033[39;49m\r > > input_parse: %0 ground, 72 bytes: \r\n[1]+ Stopped > emacs large_text_file.txt\r\nroot@milu:~# > > > > \033[?1049l is rmcup which exits cursor positioning (alternate > screen) mode. > > > > Then when you type fg, it gets: > > > > input_parse: %0 ground, 694 bytes: > \033[?1049h\033[34l\033[?1h\033=\033[24;1H\033[K\033[H\033[?25l\033[3mFile > Edit Options Buffers ... > > > > \033[?1049h is smcup which turns it on again. > > > > But sometimes, it gets: > > > > input_parse: %0 ground, 674 bytes: > \033[24;1H\033[K\033[H\033[?25l\033[3mFile Edit Options Buffers ... > > > > Where emacs is not sending \033[1049h, or in fact any of the smcup, > > cvvis, smkx sequence it normally sends. It would be nice to be able to understand what was meant by whoever wrote this, as smcup, cvvis, etc. don't tell me much (I'm not a terminfo expert). Thanks.
