From: Robert Vojta <rvojta <at> me.com> To: bug-gnu-emacs <at> gnu.org Subject: 25.2; Freeze & redisplay_internal & macOS Date: Thu, 18 May 2017 07:57:04 +0200
Hi, I do use Emacs on macOS (10.12.5) and I'm experiencing lot of freezes. What does freeze means in this context? * C-g doesn't work * kill -SIGUSR2 works (sometimes have to send it two or more times to unfreeze it, but always helps) I tried to install emacs via brew formula, tried emacs plus, tried emacs via brew cask. Same behavior in all of them. It is somehow connected with CIDER & REPL (Clojure[Script]). This freeze did happen one time only when CIDER & REPL wasn’t running. But it happens several times per hour, per day, … when the REPL is running. Even when I’m not interacting with it. It’s totally random, but when it starts happening, it’s very frequent. Next day without freeze. Another day freezing á 5 minutes. And so on. What I was doing when it freezes? * Scroll with mouse wheel * Refactor namespace * Simple typing clj code * Git fetch As you can see, basically whatever can trigger this issue. SIGUSR2 generates backtrace and it always ends up in redisplay_internal. Example: > Debugger entered--Lisp error: (quit) > redisplay_internal\ \(C\ function\)() Another example: > Debugger entered--entering a function: > * command-error-default-function((quit) "" nil) > recursive-edit() > debug(error (quit)) > ... > linum-after-scroll(#<window 3 on *Backtrace*> 2215) > redisplay_internal\ \(C\ function\)() Would like to solve this issue, but don’t know how. What else I can provide to make this report more useful?

I trashed the yesterday’s freeze backtrace (no debug info), but it was stuck in assq_no_quit & lot of functions about faces (merge_face, …). Today’s one contains:

Hi Eli, almost a week without crash. But it’s here. This line ... https://github.com/emacs-mirror/emacs/blob/master/src/xdisp.c#L14134 … always sets fonts_changed to 1 and thus … https://github.com/emacs-mirror/emacs/blob/master/src/xdisp.c#L14160 … goto retry_frame is executed and so on. It’s stuck in this loop. Going deeper to see what and why it is setting this to 1. R.

Hi,
found some time to continue with this issue. fonts_changed are modified here:
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 4.1
frame #0: 0x0000000100092643 Emacs`redisplay_window(window=4836536885, just_this_one_p=false) at xdisp.c:17288
17285 if (WINDOW_WANTS_MODELINE_P (w)
17286 && CURRENT_MODE_LINE_HEIGHT (w) != DESIRED_MODE_LINE_HEIGHT (w))
17287 {
-> 17288 f->fonts_changed = true;
17289 w->mode_line_height = -1;
17290 MATRIX_MODE_LINE_ROW (w->current_matrix)->height
17291 = DESIRED_MODE_LINE_HEIGHT (w);
(lldb)
It’s pretty hard to say why this happens, because I know nothing about Emacs internals. Going to focus on CURRENT_MODE_LINE_HEIGHT(w) and DESIRED_MODE_LINE_HEIGHT(w).

Can you see where w->mode_line_height is computed, and try to
understand why it comes out as 21 instead of 20?
Also, what is supposed to be displayed on the mode line in this
window? Something special you have there?
Thanks.

It’s caused by unicode character number 9448 (ⓨ). In 99% of cases, ascent of this character is 16, descent is 4, thus the sum is 20 and it equals to desired mode line height (20). Works like a charm. What troubles me is that sometimes the descent is 5. Sometimes means it’s totally random. For the whole week, it’s always 4, works. And boom, it’s 5 -> 16 + 5 -> 21 -> 21 != 20 and never ending loop is here. And to answer what I have in mode line - Powerline theme from Spacemacs https://github.com/TheBB/spaceline R.

And boom, it’s 5 -> 16 + 5 -> 21 -> 21 != 20 and never ending loop is here. Can you see if those instances with descent of 5 are because the character is displayed using a different font, by any chance? Another, perhaps more probable cause could be that in some cases CURRENT_MODE_LINE_HEIGHT uses the value of w->mode_line_height, and sometimes it needs to estimate the height by calling estimate_mode_line_height. Maybe something is inconsistent between the estimation and the actual value. Also, the offending character is displayed on the mode line, right? Could you please show a screenshot of a window with the mode line formatted as it should when Emacs freezes? Thanks.

Check screenshot how it looks like in almost all of them. Thanks. I see that characters in the area you highlighted overlap each other, which might already be a sing of some display problem.
