Subject: 29.0.90; Regression installing/activating packages without autoloads
Date: Thu, 04 May 2023 12:15:15 +0200

This change:

  Prevent generating empty autoload files
  dd21003878d 2023-04-30 18:42:58 +0200
  https://git.sv.gnu.org/cgit/emacs.git/commit/?id=dd21003878d

seems to have reintroduced the following issue:

  https://lists.gnu.org/r/emacs-devel/2022-06/msg00563.html

First start Emacs 29 (or 30) with a clean slate:

$ cd "$(mktemp --directory)"
$ export HOME="${PWD}" XDG_CONFIG_HOME="${PWD}/.config"
$ emacs

Then try to install the sicp package (which lacks autoloads) from MELPA:

0. C-x b RET
1. (setq package-archives '(("melpa" . "https://melpa.org/packages/")))
   C-x C-e
2. M-x package-install RET sicp RET
3. C-h e
4. C-M-S-v

Observe that *Messages* contains the line:

  Error loading autoloads:
  (file-missing
   Cannot open load file
   No such file or directory
   /tmp/tmp.5GvMpPatMo/.emacs.d/elpa/sicp-20200512.1137/sicp-autoloads)

5. M-x toggle-debug-on-error RET
6. M-x package-quickstart-refresh RET

This fails with:

  Debugger entered--Lisp error: (wrong-type-argument stringp nil)
    insert-file-contents(nil)
    package-quickstart-refresh()
    funcall-interactively(package-quickstart-refresh)
    call-interactively(package-quickstart-refresh record nil)
    command-execute(package-quickstart-refresh record)
    execute-extended-command(nil "package-quickstart-refresh" "package-quick")
    funcall-interactively(execute-extended-command nil
                          "package-quickstart-refresh"
                          "package-quick")
    call-interactively(execute-extended-command nil nil)
    command-execute(execute-extended-command)
  
The file-missing error also appears on subsequent Emacs startup.

Thanks,
