I am using package-vc to manage a few pakcages I maintain. However, in Emacs
31 I observed a couple issues.
The first discrepancy with what used to happen on Emacs 30 is when a package is
installed from a custom location, no *.elc files are produced. I don't know
what the expected behaviour should be here.
In addition to that when I attempt to rebuild such a package with
package-vc-rebuild it signals an error, which I believe shouldn't happen,
should it? In this case no *.elc files have been produced nor updated. Such a
workflow used to work on Emacs 30.
I observed this on a Emacs macport (from
https://github.com/jdtsmith/emacs-mac/tree/emacs-mac-gnu_master_exp), but the
issue is reproducible on master (68aaeb3519fd7f6176050e142f0dbc27e07992d2) as
well.
git clone https://github.com/pkryger/helm-projectile "${HOME}/tmp/helm-projectile"
emacs -Q
(require 'package)
(add-to-list 'package-archives '(melpa . "https://melpa.org/packages/"))
;; Just to avoid using existing elpa
(setq package-user-dir (expand-file-name "tmp/elpa" (getenv "HOME")))
(package-refresh-contents)
;; In my config I use hardcoded paths, but `use-package' needs a
;; string for `:load-path', so just for this sample
(let ((pkg-dir (expand-file-name "tmp/helm-projectile" (getenv "HOME"))))
(eval
`(use-package helm-projectile
:vc t
:load-path ,pkg-dir)))
;; At this point `helm-projectile' has been installed, but no *.elc files are
;; produced, which differs from Emacs 30.
(setq debug-on-error t)
M-x package-vc-rebuild RET helm-projectile RET
Which yields the following:

Could these be introduced by 4226eb2b20408ba49787195bbc59bb0066c9c9e4?
