Sometimes, gnus-summary-insert-old-articles doesn't.

Hi,

Sometimes when I'm using the nnimap backend with Gmail, if I run
gnus-summary-insert-old-articles and request, say, 10 articles, no
additional articles appear in the summary buffer.  If I try again but
ask for, say, 10000 instead of 10, then some additional articles do
appear.

Is it normal for gnus-summary-insert-old-articles to add no articles to
the summary buffer even though it says that some old articles are
available?  Since it seems I can always fetch enough old articles by
incrementally increasing the number of articles requested, this isn't a
huge problem for me.  I'm just wondering if maybe it's a bug.

Just to say that this happens to me very frequently.  And, in fact, the
number of old articles inserted is always (anecdotally) less than the
number requested.

Perhaps due to gaps in the article numbers.

Yeah, that happens to me with gmail. I think that the numbers are 
the ones in "All Mail", that is why there are gaps in "Inbox" or 
other folders.

Hi Jorge and Eric,

Thanks for the feedback!  I'm glad to know I'm not the only one.

How might I begin to troubleshoot to see if this is a bug on Gmail's
side, within my local Gnus configuration, or within Gnus itself?  I'm
mainly just curious, since like I said I can just request arbitrarily
many articles to eventually get the older ones.

I've noticed this behavior occurs not only with Gmail but also with
other IMAP email providers, as well.  Anecdotally, today I observed
using a non-Gmail IMAP service that when I requested 10 old articles, I
got less than 10, and when I requested 10 again, I got even more
articles (but still less than 10).  It's quite curious.

I don't think it's a bug, per se -- it's just how the code is written.
So far as I can tell, Gnus just calculates what the previous ten (or
however many) articles numbers *would* be, and then requests those
numbers. I haven't stepped through the code to confirm, but that's what
it looks like.

I assume it would be possible to write a generic way of requesting some
number of old articles from a backend, regardless of their actual
article numbers, but my guess is that no one will get to that very soon!

Ooof, I had completely forgotten that movie...

It does look like `gnus-summary-insert-old-articles' calculates the old
article numbers to request without consulting the backend.
