Unexpected behavior in gnus-group-list-groups after gnus-group-get-new-news

Unexpected behavior in gnus-group-list-groups after gnus-group-get-new-news

[Pankaj Jangid]

I am using Emacs from emacs-29 branch head.

Before calling gnus-group-get-new-news with ARG my group buffer looks
like this. i.e. pressing "l" gnus-group-list-groups, the group buffer
shows this.

--8<---------------cut here---------------start------------->8---
       1: nnimap+codeisgreat:golang
       1: nnimap+otp:INBOX
*      0: nnimap+otp:[Gmail]/Sent Mail
*      0: nnimap+otp:[Gmail]/Trash
       1: nnimap+otp:career
       3: nnimap+otp:cron
       1: nntp+gmane:gmane.comp.lang.go.general
*      0:*nntp+gmane:gmane.emacs.gnus.general
       1: nntp+gmane:gmane.linux.debian.user
--8<---------------cut here---------------end--------------->8---

But after I call gnus-group-get-new-news with ARG like this "C-u 1 g",
the group buffer shows only groups with level 1 and unread
messages. This is fine.

--8<---------------cut here---------------start------------->8---
       9: nnimap+otp:INBOX
--8<---------------cut here---------------end--------------->8---

But now if I press "l", the group buffer shows many old groups also,
which I subscribed at some point in time.

I'm unsure which variable or setting the l command (i.e.,
gnus-group-list-groups) refers to in this context. Is it
gnus-level-subscribed, gnus-group-default-list-level, or something else?
I'd appreciate any insights into this behavior.

Can someone explain what is going on here? To summarize: after calling
gnus-group-get-new-news with an argument and then listing groups with l,
I'm seeing old groups that I had previously subscribed to. I expect not
to see these old groups.

I cannot help you directly but I find it useful to customise the format
for displaying the groups in your groups buffer, gnus-group-line-format,
to include the level for each group.  This may help you answer some of
your questions.
