Jumps to the bottom of the buffer when used with emacs-lsp autocomplete

[XO39]

The update before the last one caused Emacs to stop working properly every time I launch it. Had to disable line-reminder back then. The last update resolved that issue, but brought along a new issue, that is when even I use autocomplete, it jumps to the bottom of the buffer. Had to disable it again.

Sorry for the inconvenience!

The launch issue was caused by saving custom-file while starting up Emacs. So I have the fix in:

line-reminder/line-reminder.el

Lines 417 to 420 in c0cebef

	(defun line-reminder--custom-file-saving ()
	"Return t if we are saving `custom-file'."
	(and (or print-escape-control-characters inhibit-read-only)
	(equal (buffer-file-name) (ignore-errors (expand-file-name custom-file)))))

I reckon the solution may not be ideal. But I couldn't think of any part of the code that would make the buffer jump to the bottom. 😅 What was the last working version for you?

Not exactly sure, but I think it was working fine up to this commit 1dff70a
It was the first update after Emacs-28.1-universal on 2022-04-04 (from Emacs For Mac OS X).
IIRC I've just finished updating Emacs (with brew), then updated Emacs packages (including line-reminder), after restarting Emacs things went south. I had to disable all the packages then enable them one by one to find out which was causing the issue.

The diff look like this: (#13)

-(defun line-reminder--custom-file-saving ()
-  "Return t if we are saving `custom-file'."
-  (and (or print-escape-control-characters inhibit-read-only)
-       (equal (buffer-file-name) (ignore-errors (expand-file-name custom-file)))))
-
 (defun line-reminder--is-valid-situation-p (&optional beg end)
   "Return non-nil, if the conditions are matched.

 Arguments BEG and END are passed in by before/after change functions."
-  (and
-   (not (line-reminder--custom-file-saving))
-   (not buffer-read-only)
-   (not (line-reminder--contain-list-string-regexp
-         line-reminder-ignore-buffer-names (buffer-name)))
-   (not (memq this-command line-reminder-disable-commands))
-   (if (and beg end) (and (<= beg (point-max)) (<= end (point-max))) t)))
+  (and (not buffer-read-only)
+       (not (line-reminder--contain-list-string-regexp
+             line-reminder-ignore-buffer-names (buffer-name)))
+       (not (memq this-command line-reminder-disable-commands))
+       (if (and beg end) (and (<= beg (point-max)) (<= end (point-max))) t)))

My assumption is this bug is caused by the newer version of Emacs, and not the changes I made?

I have tried to remove ~/.emacs.d/elpa/ and install everything from fresh Emacs, but still could not reproduce this issue. Does it affect when using emacs -q? Or does it only appears to conflict with auto-complete?

Sorry for the late reply, I've been busy like crazy these days.

I'll try to investigate more when I have more time, maybe this weekend. I'll be back to you if I found anything useful.
