"Selecting deleted buffer" error upon common commands

[mathpunk]

"Selecting deleted buffer" error upon many commands (search, buffer, file, help...)

Description :octocat:

Everything works normally on startup. But at some point --- I have not found the triggering condition --- commands like SPC f f or SPC b b or even / result in a "Selecting deleted buffer" message instead of the desired behavior.

Reproduction guide :beetle:

• Start Emacs
• Do work for a few minutes (sorry) --- I'm generally working in an org-mode file, and lately I've been using tables but I'm not sure if these are related.

Observed behaviour: :eyes: :broken_heart: "Selecting deleted buffer" is the response to many basic commands. Sometimes, but not always, one or more sometimes-incorrectly closed (defun dotspacemacs/emacs-custom-settings ()) ...) forms appear in the .spacemacs file, which I've been deleting manually to get the .spacemacs file to not crash so my configuration gets loaded correctly. Maybe this issue is like #7898 ?

Expected behaviour: :heart: :smile: Stuff works.

Backtrace :paw_prints:

I don't know how to find a backtrace because the bug kills my ability to navigate buffers.

[mathpunk]

Update: I'm trying to find a minimal example of something that breaks everything. I went from working state, to deleting rows from one org-mode table and pasting them below another org-mode table, and saved, and that resulted in breakage. I have a couple functions that run on save which I will also try commenting out from my config.

[mathpunk]

A-ha! With these two functions no longer running after save, pasting rows and saving no longer breaks everything. These are the only 'after-save-hook functions I had.

;; Tangle Org files when we save them
;; (defun tangle-on-save-org-mode-file()
;;   (when (string= (message "%s" major-mode) "org-mode")
;;     (org-babel-tangle)))

;; (add-hook 'after-save-hook 'tangle-on-save-org-mode-file)
(defun to-agenda-on-save-org-mode-file()
  (when (string= (message "%s" major-mode) "org-mode")
    (org-agenda-file-to-front)))

;; (add-hook 'after-save-hook 'to-agenda-on-save-org-mode-file)

[jdelStrother]

I've found that simply running org-agenda-file-to-front is enough to trigger this

[fiveNinePlusR]

The selecting deleted buffer happens to me from time to time as well and I cannot do a spc b b or pretty much anything until I restart emacs.

[duianto]

Killing a ranger buffer and closing the new frame that was opened, puts you in a state where a lot of key bindings show the message: Selecting deleted buffer

Reproduction steps with the ranger layer installed

Open a ranger "session": SPC a r Kill the selected ranger buffer: SPC b d The messages buffer shows:

Ranger window was overwritten. Redirecting window to new frame

and a new frame opens, where the key bindings seem to work as expected. But when the new frame is closed: SPC q f (SPC q z in the master branch). Then the initial frame gets selected and when SPC is pressed, then this message is shown:

Error running timer ‘which-key--update’: (error "Selecting deleted buffer")

The frame splits with the bottom window showing <M> where the window number used to be. The top window shows 1 as the window number. The <M> window doesn't close when the cursor is in the top window and SPC w m is pressed to maximize that window.

A lot of key bindings show these messages (without opening a new frame):

Ranger window was overwritten. Redirecting window to new frame apply: Selecting deleted buffer

SPC q r doesn't restart, it just shows the selecting deleted buffer message. But one way of restarting, is to open a new frame SPC w F, where SPC q r works.

Sometimes it's also possible to get back to normal, without restarting, by pressing SPC b n to switch to the ranger buffer. Or if the ranger buffer isn't found then open a new ranger buffer SPC a r. Press q to close it.

I'm unable to reproduce the "Selecting deleted buffer" issue with ranger. The steps above, seems to have been related to another ranger issue, where the middle column, didn't show any text for files and some folders. That issue was fixed a couple of days ago.

[duianto]

Maybe this could be helpful:

It seems most likely that you've captured the buffer object for the original (and now deleted) buffer, and have passed that object to with-current-buffer, rather than the object for the new buffer. – phils Jun 27 '14 at 5:52

[hendrikcech]

I encountered this bug for the first time a few days ago. Mostly happens when working in org-mode, but can't nail it down any further yet. I can confirm that running org-agenda-file-to-front is enough to trigger this behavior. I'm on the develop branch, using Emacs 25.1 on OS X 10.11.6 if that helps.

Has anyone found a workaround that isn't "restart emacs"?

[jb55]

This happens a lot for me recently. Only way to fix is to restart. Really annoying.

[jb55]

This reproduces it for me every time:

1. Start Spacemacs
2. SPC : customize-variable
3. org-adapt-indentation
4. Set to off
5. Click Apply and Save

[wizmer]

Any call to customize-variable followed by Apply and Save triggers the bug for me.

[jb55]

Yeah this is getting exceedingly annoying. It sometimes works and sometimes doesn't. Mostly doesn't.

I even tried wiping my .spacemacs to a clean slate and it was still doing it ???

[tekacs]

This occurs for me if I open a multi-term and kill the buffer (with SPC b d). The only way I can close multi-terms is by sending an EOF to the terminal, which isn't feasible if the application in the terminal has crashed or is spewing a lot of output, for example (but this fails even if the shell is responding).

As above, having to kill the entire session and resurrect is... not fun. :confused:

Turning off the Spacemacs layer nlinum made my problem go away. Looks like some timer in nlinum implementation was causing this issue. By default, Spacemacs comes with nlinum-relative to enable line number support. I didn't know why I added nlinum layer. I didn't notice any functionality missing after I removed that layer from my configuration.

[jb55]

Turning off the Spacemacs layer nlinum made my problem go away

I don't have this layer and I still have this problem :[

[jb55]

I was able to fix this my moving my custom-set-variables into their own file as described here: https://github.com/syl20bnr/spacemacs/issues/7891#issuecomment-285958745

[PhoenixStarEclipse]

I had the same problem, and triggering it only needs moving the cursor to some space character and wait for a few seconds.

[soverton]

I get this when calling "cider-jack-in" and the command "sesman-quit" seems to fix it.

[temco]

I get this when calling "cider-jack-in" and the command "sesman-quit" seems to fix it.

Yes, it works. I cider-jack-in the cider-nrepl and then cider-connect to another repl, then I kill the latter buffer. When I cider-connect the latter repl again, the problem is produced. Then I new a frame, sesman-quit it, and cider-connect again, it works.

[npit]

I'm getting this error when invoking any agenda view. Using the develop branch.

[duianto]

Opening org agenda views under the prefix: SPC a o o

• a Agenda for current week or day
• t List of all TODO entries
• n Agenda and all TODOs

works for me without any errors.

@npit If you meant something else, then could you provide some reproduction steps. And it might help to narrow down when the issue is occurring if you include your system info. Press SPC h d s to copy your system info to the clipboard.

[npit]

Currently, I'm getting the error when I invoke the GUI version of spacemacs, eg:

• running emacsclient -c from the terminal
• running from my program launcher in plasma KDE, with an command of emacsclient ~/path/to/file.org or emacsclient -c

On the other hand, running emacsclient ~/path/to/file.org from the terminal successfully spawns spacemacs, but in a terminal environment.

FWIW, after the *ERROR*: Selecting deleted buffer error, the messages buffer displays a warning: [persp-mode] Warning: Can not restore the window configuration, because of the error -- (error Window #<window 49 on *scratch*> too small to accommodate state)

I haven't been able to reproduce the error: Selecting deleted buffer.

But I'm able to reproduce the warning (In Linux, but not in Windows):

[persp-mode] Warning: Can not restore the window configuration, because of the error -- (error Window #<window 5 on scratch> too small to accommodate state)

By first starting Spacemacs with a Gui client, then with a terminal client:

• emacs --daemon
• start Spacemacs with a gui: emacsclient -c
• close the gui: SPC F d
• start Spacemacs in a terminal: emacsclient -nw

The warning is shown for a split second in the minibuffer during startup, then it's visible in the messages buffer.

Same.

Just updated packages.

Agenda and Magit buffers do not work.

[duianto]

I have updated packages on the latest develop branch and both org agenda and magit sems to be working.

Dodged the bullet.

-> Nuke&paving ~/.emacs helped. <-

Happens.

I can no longer provide info.

[mtyzz]

Just hit this issue after: cider-jack-in spc-b-d to kill buffer cider-jack-in attempt to start new repl

Running sesman-quit cleared the error for me and allowed cider-jack-in to work again.

[togakangaroo]

when this happens it prevents me from even closing emacs in a standard way

[dschrempf]

I had the same problem (mostly using SPC g s for magit status). I had to delete ~/.emacs.d/elpa and ~/.emacs.d/.cache. Now it works. I also reset the environement variables using spacemacs/force-init-spacemacs-env.

[AleXoundOS]

For me ~/.emacs.d deletion does not help (while keeping the same ~/.spacemacs.d). emacs version 27.2. Very annoying when having to open files 2 times with "HELM Find Files" (succeeds on the second run).
