Somehow the new overlay code in Emacs-29 changed slightly
the test to decide when to run the `modification-hooks` of overlays,
with the consequence that these hook functions end up being executed
also when text is deleted right after an empty overlay, which is
contrary to Emacs-28 behavior as well as contrary to the Texinfo doc.
* src/buffer.c (report_overlay_modification): Better reproduce the
Emacs-28 code.
* test/src/buffer-tests.el (overlay-modification-hooks):
Add corresponding test.
Fmake_indirect_buffer can be told whether to run buffer hooks since
bug#49160, but until now it ran buffer-list-update-hook irrespective
of this.
* src/buffer.c (Fmake_indirect_buffer): Don't run
buffer-list-update-hook when called with a non-nil
INHIBIT-BUFFER-HOOKS argument.
(run_buffer_list_update_hook): Don't special-case NULL argument, as
no such callers remain.
* test/src/buffer-tests.el
(buffer-tests-inhibit-buffer-hooks-indirect): Test whether indirect
buffer hooks are run regardless of whether base buffer hooks are
inhibited. Check that all three buffer hooks, not just
kill-buffer-query-functions, are inhibited.
* test/src/buffer-tests.el (overlay-modification-hooks): Remove noisy
`message' calls and use `ert-info' to log context of test
failures. (bug#59028)
(overlay-tests-start-recording-modification-hooks): ditto.
These tests had been annoying to me when run in interactive mode.
They failed to bind `kill-buffer-delete-auto-save' as needed, so they
depended on the user's settings, and they failed to mock out the
"Buffer modified, save?" prompt.
* test/src/buffer-tests.el (test-kill-buffer-auto-save): New helper
function that mocks the two different kinds of prompts that occur when
killing modified buffers that visit a file. Tests fail if expected
prompts are not issued.
(test-kill-buffer-auto-save-default): Use it, and explicitly bind
`kill-buffer-delete-auto-save' to nil.
(test-kill-buffer-auto-save-delete): Delete it.
(test-kill-buffer-auto-save-delete-yes): New test for the "yes" half
of the old `test-kill-buffer-auto-save-delete'.
(test-kill-buffer-auto-save-delete-yes): Ditto for the "no" half.
This fixes bug#58928. The patch works by moving the
`evaporate_overlays` check closer to `itree_delete_gap`.
* src/buffer.c (adjust_overlays_for_delete_in_buffer): New function,
integrating the functionality of `evaporate_overlays`.
(adjust_overlays_for_delete): Use it.
(evaporate_overlays): Delete function.
* src/buffer.h (evaporate_overlays): Delete declaration.
* src/insdel.c (adjust_markers_for_replace): Minor optimization.
(adjust_after_replace, replace_range, replace_range_2, del_range_2):
Don't call `evaporate_overlays`.
* test/src/buffer-tests.el (buffer-tests--overlays-indirect-evaporate):
Remove the `:expected-result :failed` attribute.
* test/src/buffer-tests.el (buffer-tests--overlays-indirect-evaporate):
Test evaporation of overlays triggered by deleting text in base
and in indirect buffers. Test doesn't pass at the moment.
* test/src/buffer-tests.el (test-overlay-insert-before-markers-empty):
Move code down to the other tests related to insertion. Test all
front/rear insert combinations. To make the test more clear, at least
to me, hard code all character positions.
(test-overlay-insert-before-markers-at-start): For both front-advance
modes verify that `insert-before-markers' at and overlay's start
advances it.
(test-overlay-insert-before-markers-at-end): For both rear-advance
modes test that `insert-before-markers' at an overlay's end advances
it.
(test-overlay-insert-before-markers-non-empty): Delete, replaced by
the two tests above.
The most obvious problem was the lack of support for
`insert-before-markers`, but the behavior was also different in a few
other cases.
* src/itree.h (itree_insert_gap):
* src/itree.c (itree_insert_gap): Add `before_markers` arg.
* src/lisp.h (adjust_overlays_for_insert):
* src/buffer.c (adjust_overlays_for_insert): Add `before_markers` arg.
* src/insdel.c (adjust_markers_for_replace, adjust_markers_for_insert)
(adjust_markers_for_delete): Adjust overlays directly from here.
(insert_1_both, insert_from_string_1, insert_from_gap)
(insert_from_buffer_1, adjust_after_replace, replace_range)
(replace_range_2, del_range_2): Don't adjust overlays explicitly here
any more.
* test/src/buffer-tests.el (test-overlay-insert-before-markers-empty)
(test-overlay-insert-before-markers-non-empty): New tests.
* src/buffer.c (adjust_overlays_for_insert)
(adjust_overlays_for_delete): Repeat for all buffers sharing the same text.
* src/itree.c (itree_insert_gap, itree_delete_gap): Allow an empty tree.
* test/src/buffer-tests.el (buffer-tests--overlays-indirect-bug58928):
New test.
See bug#58703.
* src/buffer.c (overlays_in): Add a new TRAILING arg expressing the
behavior wanted by `overlays-at', namely to include all overlays
beginning at the POS passed to `overlays-at', even if POS is the end
of the narrowed region. Pass true and the search range is extended to
ZV+1 if END is greater than ZV, just as is done for EMPTY.
(overlays_at): Pass 'true' for the new trailing arg. At present this
is the only caller passing 'true'.
(mouse_face_overlay_overlaps): Pass 'false' for the new trailing arg.
(disable_line_numbers_overlay_at_eob): ditto.
(Foverlays_in): ditto.
* src/editfns.c (overlays_around): ditto.
* test/src/buffer-tests.el (sorted-overlays): Add a spot test for
this.
When passed EMPTY, 'overlays_in' should return empty overlays at END.
It was doing so, but it was also returning any other overlay that
happened to begin at END.
bug#58672
* src/buffer.c (overlays_in): Don't return overlays at END unless they
are empty overlays.
(disable_line_numbers_overlay_at_eob): Pass 'false' instead of 'NULL'
for the bool 'empty' arg.
* test/src/buffer-tests.el (sorted-overlays-in): New helper function.
(test-overlays-in-empty-range): New test exhaustively covering these
edge conditions.
(test-overlays-in-empty-range-bug58672): Simple test for one case.
Correct `get-char-property` which failed to ignore empty overlays.
* src/textprop.c (get_char_property_and_overlay): Make sure the
overlay covers the character.
* test/src/buffer-tests.el (buffer-tests--overlay-bug58479): New test.
* src/buffer.h (buffer_has_overlays): Avoid `interval_tree_size`.
* test/src/buffer-tests.el: (overlay-modification-hooks) new
ert-deftest.
(overlay-tests-start-recording-modification-hooks): New function.
(overlay-tests-get-recorded-modification-hooks): New function
(bug#57150).
* doc/lispref/buffers.texi (Buffer Modification): Adjust
documentation.
* src/buffer.c (Frestore_buffer_modified_p): Fix up the logic
around `autosaved': It means "the buffer is modified, and also
autosaved".
* doc/lispref/buffers.texi (Buffer Modification): Document
buffer-modified-p returning `autosaved'.
* lisp/subr.el (with-silent-modifications): Use
restore-buffer-modified-p instead of altering the buffer modiff
(since this has other side effects like not updating after async
`display' changes.
* src/buffer.c (Fbuffer_modified_p): Allow returning whether the
buffer has been autosaved after changes.
(Frestore_buffer_modified_p): Allow adjusting whether the buffer
has been autosaved after changes.
* src/fileio.c (Fdo_auto_save): Refill the doc string.
* test/lisp/electric-tests.el (electric-pair-define-test-form):
* test/src/buffer-tests.el (buffer-tests--make-test-name): Silence
byte-compiler by defining defuns also at run time.
* doc/emacs/files.texi (Auto Save Files): Document it.

* lisp/files.el (delete-auto-save-files): Move definition to C
(since it's used in the C layer).

the old code that apparently didn't trigger for
kill-buffer/delete-auto-save-files.
(syms_of_buffer): Add new variable
kill-buffer-delete-auto-save-files and move definition of
delete-auto-save-files here (bug#21612).
* doc/lispref/display.texi (Finding Overlays): Adjust documentation.
* src/buffer.c (overlays_in): Treat the end of the buffer and the
end of the narrowed-to buffer the same (bug#19422).
(Foverlays_in): Adjust doc string.
* src/buffer.c (Fmake_indirect_buffer):
Match base buffer's inhibit-buffer-hooks.
* test/src/buffer-tests.el (buffer-tests-inhibit-buffer-hooks-indirect):
Add a test (bug#49160).
Give get-buffer-create an optional argument to inhibit buffer hooks
in internal or temporary buffers for efficiency (bug#34765).
* etc/NEWS: Announce new parameter of get-buffer-create and
generate-new-buffer, and that with-temp-buffer and with-temp-file
now inhibit buffer hooks.
