Subject: bug#2061: 23.0.60; Add preference to force load of Elisp files when they are newer than corresponding byte-compiled file
Date: Sun, 25 Jan 2009 18:19:27 -0800 [thread overview]
Message-ID: <18813.7599.138907.415045@hungover.brentg.com> (raw)
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
The load function will load a .elc file even if the .el file is newer
than the .elc file. There are warnings issued, but it is likely that
the message is lost in the ton of messages that usually are emitted,
especially during Emacs invocation.
When would the user ever prefer to load the .elc file after having
modified the .el file?
My suggestion is to add a customizable preference variable called,
say, load-prefer-newer-lisp-files (that needs a better name), that is
recognized by the load function (defined in C code). When
load-prefer-newer-lisp-files is non-nil, and when there is a .el and
.elc file, and when the .el file is newer than the .elc file, it loads
the .el file and not the .elc file (and possibly emits a warning of
this action).
Having it be a customizable preference variable avoids surprising
other users who are used to the existing behavior.
I could hack around this by fset'ing `load' to be my own function that
removes the .elc file when the .el file is found to be newer, but that
is an expensive operation involving calling such functions such as
locate-file-internal to find both .el and .elc files, testing their
modification date-time stamps, etc., operations that the `load' C
function performs already. Hence, why I think it is best to change
the load function to allow for both approaches via a preference
variable.
Thanks!
Brent
