Subject: bug#25109: 25.1.50; `symbol-file' is sometimes lying
Date: Sun, 04 Dec 2016 19:12:06 +0100 [thread overview]
Message-ID: <87shq3pnrd.fsf@web.de> (raw)
Hi,
emacs -Q:
(symbol-file 'pcase)
==> "pcase"
(require 'subr-x)
==> subr-x
(symbol-file 'pcase)
==> "/usr/local/share/emacs/25.1.50/lisp/emacs-lisp/subr-x.elc"
`pcase' is not (re)defined in subr-x.
Seems the reason for the wrong result is that the entry
(require . pcase)
in subr-x's entry in `load-history' is mistakenly treated as a
definition of the symbol "pcase".
Dunno if there are other cases like this (or unlike this). If we can't
be sure that `symbol-file' returns the correct value in any case, we
should say in the documentation that it works only heuristically. But I
guess we just need to be more accurate.
TIA,
Michael.
