Here's a patch suitable for debugging (applies to master). It's not =

From Elisp perspective, string vector + string plist constitute string
object. Or do I miss something?

It includes a pointer to the string's intervals, which is where the

You mean the char vector representing a string? But doesn't the real
string object also include the plist?

Propertizing a string doesn't mutate the string itself, though.

Hello Mattias!

> That requires a 'literal' flag for string objects and there's no
obvious space  for one, but perhaps we can grab the LSB of the
`intervals` pointer.

There was a recent report where I pointed out a segfault for `aset` on
"literal strings" (symbol names which are C strings located in the
read-only memory of the process). If you consider adding such a literal
string flag or read-only check, could this please be added there too? I
am in favor of adding immutable strings to Elisp. This would certainly
open up optimization potential for the bytecode compiler, in addition to
guarding against bugs like the one being discussed here.

Daniel

Side note: It might be interesting to have something similar to
`add-variable-watcher' and `debug-on-variable-change', but for mutable

No, but it wouldn't be very hard to add one, but it would miss a lot of =
code that has no idea whether it is working on a string literal or not.

Counter to my usual preference for static checks I'd prefer a dynamic =
warning in this case because it would be precise and the run-time cost =
would likely be acceptable.

That requires a 'literal' flag for string objects and there's no obvious =
space for one, but perhaps we can grab the LSB of the `intervals` =
pointer.

Even if such a check defaults to off, it could be enabled selectively to =
root out bugs like this one. I'll see what I can do.

I thank you (all) for looking into this and for the possible fix.
I've been opting for the built-in Org for some time to keep things
sane here, and I'll be happy to get it when it comes.
And since the commit went to the bugfix branch, it won't be too long.
Good reason to try the prerelease. :)

Best,
Gustavo.

Thanks for the clarification!
I am wondering if there is any relevant warning raised by the byte
compiler when doing something like
 (let ((str " ")) (add-text-properties 0 1 '(foo bar) str))

Indeed.
Done.

Gustavo, AFAIU, your issue might be "fixed" if you use Org version from
ELPA. If not, you will need to wait until the next bugfix release or use
git version of Org.

Indeed, since it modifies the object, it's "undefined behavior" territory.

`propertize` does not modify its string argument (it returns a new
string instead), so the `copy-sequence` here is a pure waste.

Same here.

This hunk fixes a real bug, OTOH.
Maybe you should use `(apply #'propertize` instead or `org-add-props`?

Ideally not -- setting properties on literal strings should indeed be =
avoided for a variety of reasons, one being that the byte compiler =
shares equal string literals:

(defun ff ()
  (list "abc" (let ((s "abc"))
                (put-text-property 0 3 'aa 'bb s)
                s)))

(ff)
 -> ("abc" #("abc" 0 3 (aa bb)))                 ; interpreted
 -> (#("abc" 0 3 (aa bb)) #("abc" 0 3 (aa bb)))  ; byte-compiled

`org-agenda-set-mode-name` uses the literal " " twice so if either is =
modified the other will appear to be, too. Where this setting of =
properties is done I have no idea

There is currently no automatic sharing of string literals between =
byte-code functions but this may change, and I've no idea what the =
native compiler is up to in this respect.

`propertize` is safe because it makes a copy of its string argument, so =
there shouldn't be any reason to copy that argument explicitly.

`org-add-props` calls `add-text-properties` and is clearly destructive.

Interpreted code is less affected by the problem because literals aren't =
shared throughout a function, but trouble can still occur:

(defun hh (x)
  (let ((s "abc"))
    (when x
      (put-text-property 0 3 'aa 'bb s))
    s))

(hh nil) -> "abc"
(hh t)   -> #("abc" 0 3 (aa bb))
(hh nil) -> #("abc" 0 3 (aa bb))
...

So, it really looks like compilation problem.

I am now looking into Elisp manual

    2.9 Mutability
=20=20=20=20
       When similar constants occur as parts of a program, the Lisp
    interpreter might save time or space by reusing existing constants or
    their components.  For example, =E2=80=98(eq "abc" "abc")=E2=80=99 retu=
rns =E2=80=98t=E2=80=99 if the
    interpreter creates only one instance of the string literal =E2=80=98"a=
bc"=E2=80=99, and
    returns =E2=80=98nil=E2=80=99 if it creates two instances.  Lisp progra=
ms should be
    written so that they work regardless of whether this optimization is in
    use.

So, it should be a good idea to avoid setting text properties in string
constants in general.

See the attached patch.
Though I have no clue if this is enough to fix the bug...

Same for me, when using Emacs git - origin/emacs-29 branch. Cannot
reproduce. Only the installed Emacs. I also tried using the same
./configure options. No luck.

Maybe someone who is using Linux Mint can try to reproduce? Or Gentoo.

Gustavo, what happens if you put (load "org-agenda.el") in your init.el?

So maybe replace " " with (copy-sequence " ").

Hi Eli,

thanks for looking into this.

I'm not sure it helps much, but I do have a functioning workaround,
which doesn't do much but may offer some hint on the source of the
problem. It basically "replaces" the space with a space in `mode-name`
with an `:after` advice:

    (defun gb/org-agenda-set-mode-name-advice ()
      (let ((before (butlast mode-name
                             (length (member " " mode-name))))
            (after (cdr (member " " mode-name))))
        (when (= (length before) 2)
          (setq mode-name (append before (list " ") after))
          (force-mode-line-update))))
    (advice-add 'org-agenda-set-mode-name
                :after #'gb/org-agenda-set-mode-name-advice)

I don't know why the space set in my init file is different from the
one set in `org-agenda.el`. But Ihor's insight that the problem only
happens on an installed version suggests a compilation related issue,
as he says.

Best,
Gustavo.

On the emacs-29 branch as well?  That's what I tried.

I've now tried the installed Emacs 29.0.90, and I cannot reproduce
there, either.  Not even if I invoke org-agenda twice in a row.  So
this sounds like some weird heisenbug.

Note: I tried with Emacs from Git - also cannot reproduce.
Only using installed version of Emacs 28, 29, and master. Not Emacs 27.

First time, it does not. From the second agenda rebuild onward, the
properties are there.

Thanks, but it isn't propertized here, I see a literal " " with no
properties.

What happens if you display mode-name inside org-agenda-set-mode-name:
does it have the properties there already?

1. emacs -Q
2. Create and open a new Org file with the following contents:

* TODO Task
SCHEDULED: <2023-04-14 Fri>

3. M-x org-agenda <RET> < a
4. M-: mode-name <RET>
5. Observe the third element (" ") in the list propertized unexpectedly,
despite `org-agenda-set-mode-name' using " " without properties.

I suspect some compiled shared " " object, but it should not happen with
strings, AFAIK. And it does not happen when I compile the same Org
version from Git.

I'm afraid I don't understand this bug report, and cannot reproduce
what I thought I understood from it.  Any chance of presenting a
recipe starting from "emacs -Q", for someone who doesn't use
org-agenda?

I suspect that it is Emacs-related because I see nothing wrong done on
Org side.

The code setting `mode-name' is

(defun org-agenda-set-mode-name ()
  "Set the mode name to indicate all the small mode settings."
  (setq mode-name
	(list "Org-Agenda"
	      (if (get 'org-agenda-files 'org-restrict) " []" "")
	      " "
	      '(:eval (org-agenda-span-name org-agenda-current-span))
              ...)))

Note the third " " in `mode-name' list.
Org does not modify the mode-name by side effect.

This bug is only reproducible when using built-in Org. When I tried to
reproduce with Git version of Org (the same release tag), no extra
properties are present in `mode-name'.

Hi All,

I've reported this some time ago at the Org bugtracker
(https://list.orgmode.org/878rtv9kx6.fsf@HIDDEN/T/#u) and, since I
was testing the pre-release this week and the issue is still around, I
reiterated it.  But I was asked to report it to the Emacs bug tracker
instead, thus this report.

I met a particularly strange issue related to Org Agenda's
`mode-name'.  And one space in particular, the one that is added
before `org-agenda-current-span'.  The `mode-name' for the Agenda is
set by `org-agenda-set-mode-name', and inside it we find:

#+begin_src emacs-lisp
" "
'(:eval (org-agenda-span-name org-agenda-current-span))
#+end_src

Now, this space somehow gets propertized.

A recipe for it.  Start `emacs -Q'.  Set things up:

#+begin_src emacs-lisp
(setq org-agenda-files '("~/agenda.org"))
(setq eval-expression-print-level nil)
(setq eval-expression-print-length nil)
#+end_src

Let's say =agenda.org= contains:

#+begin_src org
,* TODO Task
SCHEDULED: <2023-04-14 Fri>
#+end_src

Call `M-x org-agenda RET a'.  Now examine `mode-name' with `M-:
mode-name RET' to get:

#+begin_src emacs-lisp
("Org-Agenda" "" #(" " 0 1 (org-category "agenda" tags nil
org-priority-highest 65 org-priority-lowest 67 time-of-day nil
duration nil breadcrumbs nil txt #("TODO Task" 0 9 (org-heading t
effort-minutes nil effort nil fontified nil)) level " " time "" extra
"Scheduled: " format (((org-prefix-has-time t) (org-prefix-has-tag
nil) (org-prefix-category-length 12) (org-prefix-has-effort nil)
(org-prefix-has-breadcrumbs nil)) (format " %s %s%s%s" (format "%s"
(if (member category-icon '("" nil)) "" (concat category-icon ""
(get-text-property 0 'extra-space category-icon)))) (format "%-12s"
(if (member category '("" nil)) "" (concat category ":"
(get-text-property 0 'extra-space category)))) (if (member time '(""
nil)) "" (format "%-12s" (concat time ""))) (format "%s" (if (member
extra '("" nil)) "" (concat extra " " (get-text-property 0
'extra-space extra)))))) dotime time org-not-done-regexp "\\(TODO\\)"
org-todo-regexp "\\(DONE\\|TODO\\)" org-complex-heading-regexp
"^\\(\\*+\\)\\(?: +\\(DONE\\|TODO\\)\\)?\\(?: +\\(\\[#.\\]\\)\\)?\\(?:
+\\(.*?\\)\\)??\\(?:[     ]+\\(:[[:alnum:]_@#%:]+:\\)\\)?[     ]*$"
done-face org-agenda-done mouse-face highlight help-echo "mouse-2 or
RET jump to Org file ~/agenda.org" undone-face org-scheduled-today
face org-scheduled-today org-marker #<marker (moves after insertion)
at 24 in agenda.org> org-hd-marker #<marker (moves after insertion) at
1 in agenda.org> type "scheduled" date (4 14 2023) ts-date 738624
warntime nil effort nil effort-minutes nil priority 1099 org-habit-p
nil todo-state #("TODO" 0 4 (fontified nil)))) (:eval
(org-agenda-span-name org-agenda-current-span)) "" "" "" " Ddl" "
Grid" "" "" "" "" "" "" "" "" "")
#+end_src

So, it appears that the Org Agenda buffer's properties are somehow
getting to that particular space in `mode-name'.  It completely beats
me how it is so but, alas, it is there.

This is a problem because, depending on what the content of your
agenda is, this might result in this space getting some visually
distinctive property.  In my case, I get a blank gap in the mode-line
at this point.  I couldn't generate a simple ECM that gets this
effect.  But, at this point, it should be clear it can happen, given
these properties are there.

Best regards,
Gustavo.
