bug#59068: 29.0.50; noverlay causing indirect append issues

bug#59068: 29.0.50; noverlay causing indirect append issues

[Michael Kleehammer]

I compiled master at b7a76f288cc and two different indirect editing
packages, edit-indirect and separedit, now have the same bug.  When I
build with 69121c33e4a, which is a commit right before the noverlay
feature was merged in, I cannot reproduce the bug.

Unfortunately I don't know enough indirect buffers or overlays to
reproduce the bug with -Q, so I'll have to describe how to reproduce the
issue using edit-indirect.  If someone can suggest how to reproduce this
with only native functions, I'll be happy to test it.

I realize the bug is manifesting in non-core packages, but it certainly
appears like noverlay could have a bug they uncover.  Since the recent
email about noverlay said the only change should be speed, it is
probably worth someone looking into that knows what it could be.

Both edit-indirect and separedit offer indirect editing of a string or
comment block in another buffer.  Usually you make changes and commit
the buffer which replaces the original string or comment and deletes the
indirect buffer.  This still works fine.

However, both allow you to save which replaces the original while
keeping the indirect buffer open for further editing.  Subsequent saves
are supposed to keep replacing the original, but they now *append* to
the original.

For example:

- Mark two lines of text in a buffer.
- Execute the edit-indirect-region command which will create an indirect
  buffer with only the two lines.
- In indirect buffer add some text like "1" to one of the lines and save
  the buffer using C-x C-s.
- Verify it overwrote the two lines in the original buffer.
- In the indirect, change the "1" to "1 2" and save again.
- Now the original will show 4 lines: two lines with the "1" change and
  two lines with the "1 2" change.

Before noverlay was merged in, the second save would result in only the
two lines with the "1 2" change.

Interestingly, neither org-mode's indirect editing of a source block using
org-edit-special (C-') nor the pop-to-org package exhibits the bug.

Hi Michael.  There have been a number of fixes related to indirect
buffers very recently.  Could you please try with the latest HEAD?

And if the current master doesn't solve that, I would appreciate
recipes starting from "emacs -Q" that didn't involve additional
packages.  Just lift enough code from those packages to demonstrate
the problem in vanilla Emacs.

Thanks.

I've extracted enough from edit-indirect to reproduce the problem and attached
it.  Eval the file and follow the instructions at the bottom.

With the noverlay builds of Emacs, each commit is inserted above the original
text.  With previous builds it is not.

Let me know if I can help or if the example is not clear enough.  I'm still
working on my elisp skills, so making it a unit-test style function would take
me quite a while.

Thanks, Michael.

I'm afraid, I can't yet reproduce this.  This is with an Emacs from
23dd27a97953bab3ffab86dcc83b4e3b139657aa.  Here is what I did:

emacs -Q
C-x C-f test.el RET
M-x eval-buffer RET
M-: (test-create-indirect)
C-x b *test* RET
;; Add "- 1" to line 2
M-: (test-commit-indirect) RET
C-x b test.el RET

The lines at the top of the file are as expected

;; one
;; two - 1
;; three

(setq test-beg 1
...

Did I miss something?

Hi Michael, can you attempt to reproduce after pulling newer code?

The revision you tested at does not contain recent bug fixes.  See this
list, in particular the last commit listed.  The symptoms you describe
are consistent with the kinds of weird things that occurred before the
bug#58928 fix.

35221a7bd5 ((itree_insert_gap, itree_delete_gap): Minor optimization, 2022-11-07)

Like Gerd, I was not able to reproduce a problem using newer code.

You were correct - it does work with these fixes.  Thanks.

Michael, thank you for double checking.  I'll go ahead and close this
bug.
