Title:
gnus-summary-respool-article (B r) no longer works in emacs 24
Status in emacs24 package in Ubuntu:
Fix Released
Bug description:
In emacs24, gnus-summary-respool-article (B r) no longer works for me.
It prompts me for the backend to use (nnfolder), but then doesn't find
any servers for nnfolder and doesn't offer me any completions for the
server question and won't accept anything I type.
The relevant change appears to be this one in gnus-sum.el:
| @@ -9945,7 +10202,7 @@
| (car ms))
| (t
| (let ((ms-alist (mapcar (lambda (m) (cons (cadr m) m)) ms)))
| - (cdr (assoc (completing-read "Server name: " ms-alist nil t)
| + (cdr (assoc (gnus-completing-read "Server name" ms-alist t)
| ms-alist))))))))
| (unless method
| (error "No method given for respooling"))
If I switch it back to completing-read, gnus-summary-respool-article
works again. Looking at gnus-completing-read, it calls
gnus-completing-read-function which for me is the default,
i.e. gnus-emacs-completing-read.
Looking at that function:
| (defun gnus-emacs-completing-read (prompt collection &optional require-match
| initial-input history def)
| "Call standard `completing-read-function'."
| (let ((completion-styles gnus-completion-styles))
| (completing-read prompt
| ;; Old XEmacs (at least 21.4) expect an alist for
| ;; collection.
| (mapcar 'list collection)
| nil require-match initial-input history def)))
The problem appears to be the mapcar. If I replace it with just
'collection', gnus-summary-respool-article works again.
