Unsubscribed groups again fetched at startup

Unsubscribed groups again fetched at startup

[Matt Lundin]

When starting gnus, all unsubscribed groups in nnshimbun backends are
fetched. This means, for instance, that all 50+ New York Times rss feeds
are downloaded and parsed, even if I have subscribed only to one group
in the backend. Although nnshimbun is of course a third party package, a
thread on this list earlier this month suggested that this was an issue
affecting other backends:

In fact, this issue was fixed on September 10 with the following commit:

    gnus-start.el (gnus-read-active-for-groups): Check only subscribed groups.

AFAICT, the regression was introduced with the following commit:

    Only run -request-scan once per method on `g'.
    
    This ensures that backends like nnfolder don't open all their folders.

(If this requires a fix on the nnshimbun/emacs-w3m side of things,
please do let me know, and I would be happy to send an email to that
list.)

Thanks,

It sounds like nnshimbun activates all groups if nnshimbun-request-scan
is called without a group parameter, which is less than optimal in the
new setup...

Thanks. I sent an email to the emacs-w3m mailing list to see if
nnshimbun-request-scan can activate only subscribed groups when called
without a group parameter.

Best,
