[BUG] org-save-all-org-buffers reapplies startup visibility [9.5 (release_9.5 @ /usr/local/share/emacs/29.0.50/lisp/org/)]

[BUG] org-save-all-org-buffers reapplies startup visibility [9.5 (release_9.5 @ /usr/local/share/emacs/29.0.50/lisp/org/)]

[Marcel van der Boom]

Summary:
When calling `org-save-all-org-buffers` the initial visibility 
setting as specified in `org-startup-folded` or specified in 
=#+STARTUP: overview= will be applied to the org buffer in view.

My usecase is that `org-save-all-org-buffers` is called in an idle 
timer and makes working on org files annoying, as the outline 
keeps changing all the time, for example after returning from an 
interrupting phonecall.

To reproduce:

- create two files:

test.org:

--8<---------------cut here---------------start------------->8---
  #+SETUPFILE: ~/test-config.org

* Header one
  Test header folding on save all buffers
** Header two
  This will collapse after calling org-save-all-org-buffers
--8<---------------cut here---------------end--------------->8---


test-config.org;

--8<---------------cut here---------------start------------->8---
#+STARTUP:overview
--8<---------------cut here---------------end--------------->8---

- emacs -Q test.org
- make sure the outline is unfolded
- make a change so test.org is 'dirty'
- M-x org-save-all-org-buffers

Observed behaviour:
The outline in test.org will collapse and only show 'Header one'

Expected behaviour:
Outline state does not change on calling `org-save-all-buffers`

I tried to follow the above steps with Emacs 27.1, and Org mode latest
main branch as well as the release_9.5 tag. The only different step I
took was this:

emacs -Q -L ~/src/org-mode/lisp/ ~/test.org

When I modify the test.org and call org-save-all-org-buffers, all the
headings remain unfolded. I tried to switch to a different buffer and
called the function, but still it remained in overview state. Maybe
someone with the latest Emacs build from master can try to reproduce?

The behavior of `save-some-buffers' PRED argument changed 
recently:

https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=a9ad3d477441feefa3bf6107d58281cb64e0e78a

If the PRED returns a function, that function is called.
Since `derived-mode-p' returns the symbol `org-mode', Org is being 
reloaded in modified buffers.
That's what is causing the visibility change. 
This could also have other undesirable behavior such as running 
the mode hook, resetting buffer-local variables, etc.

The attached patch ensures we're returning a boolean from the PRED 
function.
Tested with:

Subject: [PATCH] lisp/org.el: (org-save-all-org-buffers): Prevent `org-mode'
 reload

* lisp/org.el: (org-save-all-org-buffers): Ensure `save-some-buffers' PRED returns boolean.

As of this upstream commit:

https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=a9ad3d477441feefa3bf6107d58281cb64e0e78a

`save-some-buffers' will call its PRED argument if it returns a function.
Since (derived-mode-p 'org-mode) returns the symbol org-mode,
and org-mode is a function, org-mode is reloaded in modified Org
buffers when calling `org-save-all-org-buffers'. Among other
undesirable behavior, this will cause the buffer's visibility to be
reset to its initial visibility.

I can confirm this too.

(defun org-save-all-org-buffers ()
  "Save all Org buffers without user confirmation."
  (interactive)
  (message "Saving all Org buffers...")
  (save-some-buffers t (lambda () (derived-mode-p 'org-mode)))
  (when (featurep 'org-id) (org-id-locations-save))
  (message "Saving all Org buffers... done"))

If I comment out this change to the function save-some-buffers, then org-save-all-org-buffers works again.

Re: [BUG] org-save-all-org-buffers reapplies startup visibility [9.5 (release_9.5 @ /usr/local/share/emacs/29.0.50/lisp/org/)]

Your analysis is correct. I looked into this a couple days ago.
See the following message for an explanation and a patch (testing 
appreciated):

Re: [BUG] org-save-all-org-buffers reapplies startup visibility [9.5 (release_9.5 @ /usr/local/share/emacs/29.0.50/lisp/org/)]

 It works on my system with native compilation on macOS 11.6. I made the change to org.el that is in my local clone of the emacs master branch and recompiled.

Looking at the Help for the function, I see it is native compiled Lisp in my test here.

- *Help* - buffer
org-save-all-org-buffers is an interactive native compiled Lisp
function in ‘org.el’.

Thanks for the analysis and fix.
