Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
emacs is now generating .el files that do not build reproducibly.
Specifically, it adds "Generated package description from <fullpath>"
to these files that then get installed under the
/usr/share/emacs/site-lisp/elpa-src dir. This seems to be affecting
most packages that use dh-elpa.
Here's nose-el, for example:
-;;; Generated package description from
/build/1st/nose-el-0.1.1/debian/elpa-nose/usr/share/emacs/site-lisp/elpa-src/nose-0.1.1/nose.el
-*- no-byte-compile: t -*-
+;;; Generated package description from
/build/2/nose-el-0.1.1/2nd/debian/elpa-nose/usr/share/emacs/site-lisp/elpa-src/nose-0.1.1/nose.el
-*- no-byte-compile: t -*-
Patch attached that drops this particular filename; it probably isn't
very useful in a Debian package context. An alternative approach could
be to regexp it down to "nose-0.1.1/nose.el" or similar; I suppose my
patch is more of an exact clarification on the issue rather than a
request for it to be fixed in this specific way.
