Subject: 24.3.93;
 tramp persistency file: incompatible with old versions? Tramp won't
 start!
Date: Fri, 19 Sep 2014 23:26:48 -0400

After upgrading to [Aquamacs based on] a pre-release of 24.4, a user complained about Tramp not working.

Some investigation showed that the error was reproducible with a 

(load “tramp” nil)

and it occurred when it tried to load the file specified in `tramp-persistency-file-name’.  The error message was:

eval-buffer: Invalid function: (["scpc" "dr” “xxx.yyy.org" nil] ("uname" "Darwin 9.8.0") ("test" "test") ("remote-path" ("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/usr/local/bin")) ("remote-shell" "/bin/sh") ("~" "/Users/dr") ("readlink" nil) ("perl-file-spec" t) ("perl-cwd-realpath" t) ("perl" "\\perl") …)


The file contents of the file specified in tramp-persistency-file-name began with

> ; Tramp connection history.  Don't change this file.
> ;; You can delete it, forcing Tramp to reapply the checks.
> 
> ((["scpc" "dr" "braeburn.aquamacs.org" nil]
>   ("uname" "Darwin 9.8.0")
>   ("test" "test")
>   ("remote-path"
>    ("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/usr/local/bin"))
>   ("remote-shell" "/bin/sh”)


This does not look like a file that can be loaded with `load’.

It was probably produced with an older Emacs version, but judging from the file date, probably just the previous release 23.3.

Deleting the file makes the error go away.  Tramp works just fine then.

I think Emacs should be smart enough to handle the version upgrade.  Perhaps re-generating the file if reading it produces an exception should be a transparent and automatic measure.

And you get to fix the bugs that result from that! :)
