BUG: org-cycle does not unfold some subtrees

BUG: org-cycle does not unfold some subtrees

Maybe I missed a known bug when doing the research. But all the other
reports describe different and reproducible behaviour.

Sometimes (often) I cannot unfold a subtree. It then affects only one or
more subtrees while others in the same buffer or even the same branch still
work. The only fix then is to either cut and paste the affected branches,
or to close and reopen the file.

While quite frequent I have not achieved to reproduce the issue. It just
happens after a while of using multiple files navigating with search, tab
from agenda, org-refile, and cycle.

Based on my analyses it's not the cycle functions, but must come from
broken text attributes. Even (org-fold-core-region (point-min) (point-max)
nil) does not unfold the affected subtrees then. Assuming that
(org-fold-core-region) is the only place where the folding and
hiding happens, I expect the problem there. But I understand too little
about the emacs internals to debug this function.

I hope this helps to fix the issue.

May you please put a point right before the problematic fold, run
M-x describe-text-properties <RET>, and share the contents of the newly
displayed buffer listing all the text properties?

This is with the cursor on the first asterisk:
Text content at position 299:


There are text properties here:
  display              [Show]
  face                 org-level-1
  fontified            t

I could not test more positions because I accidentally cut it, and even an
undo fixed it. I would have to wait until it happens again.

Well. This shows nothing.
I am more interested in text properties at the fold.

Sure. Let me know when you are able to get more info.

I meet an unfold-able headline now. Then I record a video to show this
unfold-able headline. I executed command "describe-text-properties".
Afterwards, I closed the buffer, then re-open the file to show the
headline can be expanded normally, and show the subtree content.

Here is the uploaded video (P.S, I know video link is not a good way to
archive information in mailing list, but this problem seems can't be
text-described simply. Sorry about this.):

Please put the cursor right before the fold ("..."), execute M-x
describe-text-properties and share the properties description text.
You don't need video to share the property details buffer contents.

If you have both Org fold overlay and text properties at the same time,
you are doing something funny with `org-fold-core-style'. If you do set
it, please only do it before Org is loaded.

I'm not doing anything with org-fold-core-style directly. The only maybe
relevant thing I do after (org-mode) is:
(straight-use-package 'org-modern)
(global-org-modern-mode)
(setq org-pretty-entities t)
(setq org-pretty-entities-include-sub-superscripts nil)
(setq org-ellipsis "…")
(setq org-modern-hide-stars nil) ; somehow fixes indentation of body

And I think that I can only do it after loading org-mode.

I do not think that org-modern can be a culprit.
But some third-party package might be.
May you try disabling various extra packages and see if the problem persists?

If it helps, I get this bug using the Spacemacs Org mode layer and 
Emacs 27.

Sorry, but it does not help.
Without reproducer, I can only guess.

And I do not see any bug reports in Spacemacs repo. So, you likely has
something else contributing.

OK, that helps.

For me, the bug bites intermittently.  I often run an Emacs 
instance for more than a week before I'm bitten, so it will likely 
be a long process to work through the packages loaded on top of 
what Spacemacs loads to make a reproducer.

Also, I anticipate a problem deciding that removing a package has 
squashed the bug; will two weeks without the bug be long enough? 
Three?  Four or more?

I've found that I can work around the bug by moving the headline 
up or down.  Once this is done, the headline unfolds.  Then, when 
I move it back to its original position, it still unfolds 
properly.  For me, this is easier than my first workaround, which 
involved stopping and re-starting the Emacs instance.

Possibly related, I intermittently get bits of text following the 
ellipsis that indicates a folded headline.  My impression is that 
this happens when the bug has bitten a folded headline, but if I 
remember correctly, the bug and the bits of text following the 
ellipsis are not on the same heading.  I'll check systematically 
next time I see this, if you think it might help.

All the best,
Tom

Others in this thread appear to be affected more frequently. So, you may
get lucky just by following the thread.

You can try

In case it's helpful, I set debug-on-variable-change as you 
suggested but was bitten by the bug without triggering the 
debugger.

I was alerted to the bug bite when I noticed some folded content 
after the ellipsis on two headlines, both of which folded and 
unfolded without issue (modulo the content after the ellipsis). 
In both cases, the content after the ellipsis consisted of links 
from an Org table, and just those links.  When I fold the parent 
of a misbehaving headline, the links follow the fold and show up 
after the ellipsis of the parent.  The headline that would not 
unfold did not have content after the ellipsis.

I have some ideas about what might have triggered the problem with 
links after ellipses and will check systematically when I find 
time.

Let me know if you have questions.

All the best,
Tom

Which likely means that something is calling folding functions from
outline.el instead of Org-native folding.

What could be called. It's not org-fold-core-style.

Can I be just a data corruption of the text properties? I've no idea what
they are exactly, and what other parts use them. Maybe a conflicting key,
or failed optimization, or side effect on the regions they apply to. I just
want to give ideas from somebody who is free of knowledge.

My guess is that the issue is within org-mode. But tell us, what functions
we should look for in our code and the used packages.

I am not really sure.
In order to avoid these situations Org advices `outline-flag-region'.
But something may apply outline overlays bypassing that function, in theory.

If your `org-fold-core-style' is set to 'text-properties (default),
folding in Org should never ever use overlays that were observed in this
thread.

I am 99% sure it is not within Org.

Excellent!

Would it be useful for me to search for calls to the folding 
functions from outline.el in the source code of the Org packages 
that Spacemacs and I load?

If so, tips on how to do this efficiently are welcome.

All the best,
Tom

I have another thought now.
Do you happen to use built-in Spacemacs' search module?
If so, what if you switch it do isearch?
See https://github.com/emacs-evil/evil/issues/1630

You can also try running
(org-fold-core-set-folding-spec-property 'org-fold-outline :isearch-open nil)
to see if the problem stops happening.

This problems happens to me regularly, and I don't use Spacemacs.  Wherever it 
is, I don't think it's in there.

And if it helps further, I have had this problem for some time now.  The
solution, for me, is to search for some text I know is present in the
folded section and it unfolds!  But the situation is sporadic and I
cannot reproduce it at will.

Does it also help if you run M-: (org-fold-core--clear-isearch-overlays)?

I'll try to remember to try that next time the non-unfolding occurs.  I
should have added that I typically use evil-mode for org files, noting
that others have talked about spacemacs.

Curious.
This function is supposed to be run upon finishing or aborting isearch.
What is the value of `isearch-mode-end-hook' in your Org buffers?

(anzu--reset-mode-line org-fold-core--clear-isearch-overlays t)
Local in buffer conforguration.org; global value is nil

I checked in a few buffers, and it always says it's local in that buffer, with 
global value of nil, if that matters.

This looks right.

I am wondering how it could be that `isearch-mode-end-hook' does not get
called.

Have you experienced slowness of isearch? Did you abort it in any
special ways?

No and no, but now that I'm thinking about searching, I remember I use Swiper 
(and Ivy and Counsel).¹  C-s runs =swiper=, which is =isearch-forward= "with an overview," as it 
describes itself.

If we've narrowed it down to searching, could it be connected to that?  To the 
other people with this problem: do you use Swiper?

I am looking at
https://github.com/abo-abo/swiper/blob/master/swiper.el#L980 and I note
that swiper calls `isearch-filter-predicate', but not
`isearch-mode-end-hook', which indeed explains why the isearch overlays
are not converted back to proper Org folds.

Does it help if you try the following variant of `org-fold-core--isearch-filter-predicate-overlays':

(defun org-fold-core--isearch-filter-predicate-overlays (beg end)
  "Return non-nil if text between BEG and END is deemed visible by isearch.
This function is intended to be used as `isearch-filter-predicate'."
  (when isearch-mode (org-fold-core--create-isearch-overlays beg end)) ;; trick isearch by creating overlays in place of invisible text
  (isearch-filter-visible beg end))

Apologies. This message sent from my phone. Yes, I use swiper. My folding problems went away when I set org-fold-core-style to ‘overlay. Limited testing.

I think I found a way to consistently reproduce the issue:
>>>
* h1
aaaaa
* h2
bbbbb
* h3
bbbbb
* h4
ccccc
<<<
Collapse all. All is fine at this time.
At pos-min call (query-replace) bbb -> zzz: Already when asking whether to
replace it cannot expand. h2 and h3 are expansion is broken.
(org-fold-core--clear-isearch-overlays) repairs it.
At pos-max (query-replace) bbb -> zzz does not find a match, and does not
break the expansion.

I confirm this recipe.  For me and with my
configuration, as with emacs -Q, I then cannot unfold
h2.

This is also the case with my configuration, as with
emacs -Q.

Then I can unfold all headings and see that the
replacement bbb --> zzz worked.

Thanks!
I now came up with another, more reliable, workaround.
Since `query-replace', evil, and swiper all arrange the call of
`isearch-clean-overlays', I can advice it to make sure that we clean
everything at the end.

Fixed, hopefully, on main.

The fix did fix it for me, and the problem went away.  It did seem to introduce 
a new problem with searching in a buffer with Swiper, where the search would 
fail or throw an error or require me to collapse headings before it would work, 
but that hasn't happened in a while and I didn't try to debug it.

The issue is still easy to reproduce:

* h2
bbbbb
* h3
bbbbb
* h4
ccccc
<<<
Fold all. On * h1 call swiper-isearch, enter bbb and select the first

If you repeat it and select the second match then h3 cannot be unfold
anymore, but h2 works again.
(org-fold-core--clear-isearch-overlays) still fixes the buffer.

I don't know how to get swiper activated in a "clean" manner from there. In
my operational set-up everything is based on straight.

But anyhow it seems to be a known issue in the swiper community:

Feel free to share it. Basically, it should be enough to ask testing
using Org dev branch.

I got similar result:


#+begin_example
Text content at position 33755:


There is an overlay here:
 From 33755 to 36387
  evaporate            t
  invisible            org-fold-outline
  isearch-open-invisible delete-overlay
  org-invisible        org-fold-outline
  priority             5


There are text properties here:
  face                 org-level-2
  fontified            t
  isearch-open-invisible org-fold-core--isearch-show
  isearch-open-invisible-temporary org-fold-core--isearch-show-temporary
  jinx--pending        t

#+end_example

#+begin_example
Text content at position 36387:


There are text properties here:
  fontified            t
  isearch-open-invisible org-fold-core--isearch-show
  isearch-open-invisible-temporary org-fold-core--isearch-show-temporary

#+end_example

I confirmed I have NOT set `org-fold-core-style` to 'overlay.

Seems I have same reason with Michael.

I recorded a new video which contains the Edebug process. Which shows
the `org-cycle' function internal status data. Ihor, hope this can help
you find the reason.

I got same problem many times. Usually I close buffer and re-open file again.
I can confirm this issue. I will provides some info help here too.
