Subject: 27.0.50; ultra long tramp entries in recentf file
Date: Sun, 8 Apr 2018 21:21:30 +0200

I have a recentf file containing only 171 lines but it's 56MB big! Due to
its large size loading and closing emacs is slowed down.

The large size is due to a few tramp entries like the following (each 
entry consumes approx 10MB):

  #("/ssh:user <at> host:/file1" 1 4 (match-part #("/ssh:user <at> host:/file2" 1 4
   ....

I guess that this is either a bug in recentf or in tramp.

I cannot reproduce it locally. Usually, I don't use recentf. For testing
I've enabled it via `M-x recentf-mode', closed Emacs, and started a new
Emacs session. Visiting the recentf file, it doesn't look suspicious.

Do you reproduce the problem with a similar setting, starting with
"emacs -Q"?

Could you send me your recentf file? Maybe I'll see something Tramp
related there.

Best regards, Michael.

Hi Michael,

no I can't reproduce it neither using emacs -Q nor with my current emacs 
setup. I regularly update and recompile emacs and my installed elisp 
packages. Approx. 2 weeks ago I noticed that closing emacs takes longer 
than 10sec, but I didn't investigate this further until yesterday.

My recentf config is quite simple:

(setq recentf-save-file (concat thi::cache-file-dir "/recentf"))

(require 'recentf)
(recentf-mode 1)
(setq recentf-keep '(file-remote-p file-readable-p))
(setq recentf-max-menu-items 60)
(setq recentf-max-saved-items 500)
(setq recentf-exclude '("COMMIT_EDITMSG"
                        ".newsrc-dribble"))

I'll keep an eye on this issue.
