Auto-save filename hijacks `C-x C-s`: file contents are written to auto-save file and not to original filename #7927

Closed riccardomurri closed 4 years ago

riccardomurri commented 7 years ago

Description :octocat:

Auto save file name #file# replaces the "real" file name in C-x C-s save operations. In other words, when I press C-x C-s the auto-save file is updated and the file that I had originally opened is not written to.

In the buffer that shows this behavior, I can see this from Lisp code:

evaluating (buffer-file-name) returns the "wrong" (i.e., auto-save) filename
evaluating buffer-file-truename returns the "right" (i.e., original) filename

I have this in my .spacemacs.d/init.el::

;; Location where to auto-save files.
dotspacemacs-auto-save-file-location 'original

Reproduction guide :beetle:

Unfortunately I cannot give steps for deterministically reproducing it. It happens frequenty on my setup, but I could not yet find out the exact conditions that trigger the bug.

Observed behaviour: :eyes: :broken_heart:

C-x C-s saves content to auto-save file.

Expected behaviour: :heart: :smile:

C-x C-s saves content to the file name that was originally opened.

Screenshot shows the wrong filename (on line 1 of Emacs' buffer list).

I am having the same problem, and it seems intermittent. Happened twice today when I was frequently using 'SPC f s' (save-buffer), but I can not reproduce it. I have this in my .spacemacs file, defun dotspacemacs/init () (setq-default :
