Hi Eli,
My strategy after the previous patch is summed up by this function:
--8<---------------cut here---------------start------------->8---
(defun smtpmail-async-send-it (cleanups)
(let ((tembuf (generate-new-buffer " smtpmail temp"))
(smtpmail-code-conv-from
(if enable-multibyte-characters
(let ((sendmail-coding-system smtpmail-code-conv-from))
(select-message-coding-system)))))
(smtpmail-prepare-mail tembuf smtpmail-code-conv-from)
(push #'(lambda () (kill-buffer tembuf)) cleanups)
(make-thread #'(lambda ()
(smtpmail-send-mail tembuf)
(mapc #'funcall cleanups)))))
--8<---------------cut here---------------end--------------->8---
That is, I'd like carry around a 'cleanups' list that holds all the
functions that needed to be called after the mail was sent.
I then need to propagate this 'cleanups' parameter to callers of
'smtpmail-send-it'. The problem is that encounter code with the
following form:
--8<---------------cut here---------------start------------->8---
(unwind-protect
(let (haha)
(do)
(many)
(things)
(smtpmail-send-it-or-one-of-its-caller)
(run)
(other)
(stuff))
(kill-some-top-level-buffer))
--8<---------------cut here---------------end--------------->8---
I'm tempted to put '(run)(other)(stuff)(kill-some-top-level-buffer)'
into the cleanups list and remove the unwind-protect but then if
something goes wrong before sending the mail the
'(kill-some-top-level-buffer)' part won't be called. OTOH, if I let the
'(unwind-protect… (kill-some-top-level-buffer)' in place I could shoot
myself in the foot with the code that use this buffer into the thread.
So I guess, my question is how does one mix Lisp thread with
unwind-protect?
Best regards,
