Very nice detective work. Thank you. > * Steps to reproduce the bug [...] Yep, I can reproduce it on my end. The culprit is a8e812e60 (org.el: Restore the scroll position after cycling, 2020-09-05). However, at the time of that commit, the change didn't trigger the hang with the default Org settings. However, once that commit was merged to master (5beeb094a), it started to trigger it with the standard Org settings because the default value of org-startup-folded changed to showeverything (88f5ed91c). Anyway, this is fixed (on my end, at least) by 4f8ac0a7a.
Bug: Having '%p" in frame-title-format makes org-mode to freeze [9.4 (release_9.4-134-g0d525c @ /home/massimo/bugreport/org-mode/lisp/)]
Hi all,
I recently came across this weird issue using org-mode. Essentially
when I fold/unfold/fold some header in org-mode, pressing tab three
times,
I expect the section to fold again at the third keypress, and instead
emacs freezes. By detective work I discovered that it has to do with
having the '%p' option in
frame-title-format. The bug disappeared when I took "%p" option away
from frame-title-format.
Thank you for all you work and for any attention you will give to this
bug. I hope this message is useful.
I will now give enough info and data to reproduce the bug with a
minimal setup, and at the end of the message my emacs/org/Linux
configuration follows.
* Steps to reproduce the bug
Note that these steps only reproduce the bug when emacs runs
graphically. Using "emacs -nw" fails to reproduce the bug.
** Step 0. Prepare a folder ~/bugreport/ with the three files
"test.sh", "test.el" and "test.org" as follows
test.sh downloads org-mode and runs emacs with the test setup
cd ~/bugreport/
git clone https://code.orgmode.org/bzg/org-mode.git
cd org-mode/
make autoloads
cd ~/bugreport/
emacs -Q -l test.el test.org &
-
--- test.el loads org-mode from the repository and set frame-title-format
(add-to-list 'load-path "~/bugreport/org-mode/lisp")
(setq frame-title-format '("%p"))
-
test.org just an org file with a header
* Try to hang emacs
To hang emacs you should fold/unfold/fold the header of this section
a couple of times.
-
** Step 1. Run the test
It is sufficient to go "cd ~/bugreport/" and do "sh ./test.sh"
You should see emacs starting and opening "test.org" file, and by
running 'org-version' you could double check that the appropriate
version of org has been loaded.
** Step 2. Make emacs freeze
Go to first line in the "test.org" file and press TAB three times.
Emacs should freeze now.
