[BUG] Org-persist

[BUG] Org-persist

[Christian Moe]

Hi,

It seems my org-persist cache has somehow been corrupted so that opening
any Org-mode file suddenly causes this odd and severe error:

File mode specification error: (wrong-type-argument listp
£”6C?’^c)

Retyping the above since the characters may turn out wrong:
(wrong-type-argument listp \277\243\254\224\3236\214C?\343\222^c)

This essentially disables Org-mode completely. Only the first few lines
are fontified, or more often none, and org functions like folding don't
work. The same if I set the buffer to text-mode and then back to
org-mode.

What is a recommended quick fix?

--

A few extra notes:

Weirdly, after closing all buffers except for *scratch*, I keep getting
the same error when I try to exit Emacs, so I cannot exit.

I can open Org files with emacs -Q.

I don't know how the corruption happened. I have had some irregular
shutdowns, etc., but this appears to have happened in the middle of an
otherwise normal Emacs session.

Yours,
Christian

Fixed: I killed emacs, deleted ~/.cache/org-persist/, and things look
OK after restart.

Sorry, obvious solution, but I wasn't thinking straight last night.

I do have a backup of the org-persist directory if there's anything to
be learned from it about how this happened (but I'm traveling, and don't
have much time for forensics at the moment).

Yours,
Christian

I don't think so. Not in this case.
I think that we simply need to do format check when reading the index
and refuse to load it when something is off (malformed lists or values).

AFAIU, what you see can happen in peculiar situations when the file is
corrupted, but partially - Emacs is still able to `read' it into Elisp,
but the result of reading is garbage.
