issue of gnus daemon

issue of gnus daemon

[Binjo]

hi,

i use gnus demon to retrieve mail, and my settings as follows:

#v+
    ;; idle 2 minutes, then check news every 3 minutes.
    (gnus-demon-add-handler 'binjo-gnus-group-get-new-news 3 2)
#v-

it turns out the recent changes do not obey what the info said.

M-: (info "(gnus) Daemons")

#v+
   If IDLE is a number and TIME is a number, the function will be
called every TIME minutes only when Emacs has been idle for IDLE
minutes.
#v-

wheras from the *imap log* buffer, i can confirm it runs
`gnus-demon-run-callback' exactly every 3 mins, no matter emacs is idle or
not. that's weird.

09:39:00 202 UID FETCH 1:* FLAGS
09:39:00 203 EXAMINE "Dropbox"

09:42:00 272 UID FETCH 1:* FLAGS

...
09:45:00 342 UID FETCH 1:* FLAGS
09:45:00 343 EXAMINE "Dropbox"
...

i'm not able to figure out where's the problem though :<

the following patch resolve issue when using such daemon handler anyway:
(gnus-demon-add-handler 'binjo-gnus-group-get-new-news nil 2)

What's the returned value of (gnus-demon-idle-since)?
It should be 0.0.

Which Emacs are you using?

yes. i can't check this return value while typing though... the demon routine
still being called while i was typing in other buffers.

I do not understand how it's possile. :)

Can you C-h v timer-list and paste me the entry containing
gnus-demon-run-callback?

gnus-demon-run-callback executes binjo-gnus-group-get-new-news with the
condition:

    (when (or (not idle)
              (<= idle (gnus-demon-idle-since)))

But `idle' is 2 in your case, and since (gnus-demon-idle-since)
returns 0, I do not see what can be wrong. :(

yeah, it's weird.. i just tried to set `debug-on-entry' of
gnus-demon-run-callback, and check (gnus-demon-idle-since), but still can't
figure out what's wrong here. :-(

i may have to adopt "(gnus-demon-add-handler 'foo nil 2)" now.

thanks for your time.
