Subject: 27.0.50; Gnus cannot start
Date: Sun, 24 Mar 2019 23:09:05 +0100

I checked out and buil Emacs from master today 24-03-2019.

I started Gnus using my usual configuration (see
https://github.com/bzg/dotemacs/blob/master/emacs.el) and got this
error:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  <=(nil 6)
  gnus-get-unread-articles(nil nil)
  gnus-setup-news(nil nil nil)

  funcall-interactively(execute-extended-command nil "gnus" "gnus")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

Starting Gnus *without* a .newsrc.eld file, I can list local groups
from my dovecot local IMAP server, but I get another weird behavior:
after leaving the summary buffer, the group I just left is listed one
more time; if I enter the group and leave it again, I get three groups
of the same name in the group buffer, etc.

To read Gnus using my .newsrc.eld file again, I tried to revert back
to Emacs 26.0.92 but now Emacs seems unable to read my .newsrc.eld at
all.  Is it possible that recent changes against Gnus changed the way
Gnus parses .newsrc.eld?

Copying Eric, as he seems to have been active on Gnus recently.

Thanks for your help,

This is frustrating -- this was the most important part of the patch,
and the part I thought I'd tested most thoroughly. At worst I think Gnus
may be trying to read .newsrc.eld using the wrong encoding, so I don't
think you will have lost anything permanently. (Still, I'm very sorry
this is causing you Gnus outage.)

First -- did you run "make bootstrap" before running this new version?
Second, can you tell me if your non-ascii group names are being saved in
.newsrc.eld in utf-8, or if they have literal byte sequences in them?

Thanks,
Eric

Confirm for me, non-ascii group names are now being saved in literal
byte sequences in them. Here's an example:
"nnimap+AIA:Union/\316\224\316\243-\316\243\317\211\316\274\316\261\317\204\316\265\316\257\316\277\317\205"

Didn't have any such issues before. Compiled using "make bootstrap", 3
days ago (and today).

Actually, I'm fairly sure that that's how Gnus has always done it, and I
tried not to disturb that. But obviously I've done something wrong along
the way and I think one part of Gnus is using a decoded version of the
group name, and another part is using the encoded version.

Are you seeing duplicate group names? Would you check
(text-properties-at (line-beginning-position)) on both of the duplicated
groups, and tell me the value of the 'gnus-group property' for both?

Thanks,
Eric

I didn't see any duplicate groups in my .newsrc.eld file.
Output on above nnimap group (with literal byte sequences) is:
(fontified t)

Hi Eric,

good luck with fixing this.

No.  I regularily build Emacs from the master branch but I only use
`make' to compile it then.  I had no idea I had to `make bootstrap'.
Why was it necessary after your commit?

There is no literal byte sequence in the .newsrc.eld file that I was
able to backup, right after I got this Gnus initialization error.

Now I recompiled an Emacs from before your commit.  Starting with my
backup does trigger this error:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  intern(nil [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ...])
  gnus-make-hashtable-from-newsrc-alist()
  gnus-read-newsrc-el-file("/home/guerry/.newsrc.el")
  gnus-read-newsrc-file(nil)
  gnus-setup-news(nil nil nil)
  #f(compiled-function () #<bytecode 0x1559c202fd35>)()
  gnus-1(nil nil nil)
  gnus(nil)
  funcall-interactively(gnus nil)
  call-interactively(gnus record nil)
  command-execute(gnus record)
  execute-extended-command(nil "gnus" "gnus")
  funcall-interactively(execute-extended-command nil "gnus" "gnus")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

... so I suspect I did not save my .newsrc.eld in time to properly use
it with a stable Emacs (too bad).

I hope I will be able to find my group subscriptions and my marks.

I'm trying to better understand a few things, can you educate me?

What is the Gnus "active" file?
Where is it on my computer?
What is the .newsrc.eld file?
What is the difference between .newsrc.eld and the active file?

Thanks,

Sorry to butt in, but I have a slightly different gnus issue with Emacs
27.0.50 (build 1, i686-pc-linux-gnu, GTK+ Version 3.14.5) of
2019-03-24. Before building, I had deleted all the .elc files in
lisp/gnus. When I launch gnus it fetches the gmane news and imap mail
satisfactory, but throws a warning on nnrss feeds I've not seen before:

Warning: Warning - invalid active: "nnrss:AnnPhys" 2059 1 y; Warning -
invalid active: "nnrss:JMO" 284 1 y; Warning - invalid active:
"nnrss:PRA" 307 1 y; Warning - invalid active: "nnrss:PRL" 852 1 y;
Warning - invalid active: "nnrss:ProcRSocA" 141 1 y; Warning - invalid
active: "nnrss:JPhysA" 133 1 y

I don't get this warning using emacs-26.1. I'm using Debian 3.16.59-1
(2018-10-03) i686 GNU/Linux.

Best wishes,

Colin.

FWIW, I also had the same kind of warnings with 27.0.50.

It is like an index; see (info "(gnus) The Active File").

I believe it lives on the remote server, and is perhaps/probably cached
during operation and depending on your configuration.

A Gnus startup file; see (info "(gnus) Startup Files").

The former locally records personal state, whereas the latter remotely
records server state.

This part of the bug, thankfully, is fairly simple, and I think the
attached patch will fix it. Will one or more of you apply this and give
it a shot?

My commit changed the definition of some macros, and some *elc files
with the older definitions are still hanging around. This does happen
from time to time when you're running master, though in this case it
coincides with a real bug. You can also just delete all the *elc files
in lisp/gnus and run regular "make". This will fix some of the problems
you're seeing, though from the backtrace below and your previous report
it looks like you've also maybe got a literal "nil" as a group name in
your newsrc.eld.

But there are group names with properly-encoded non-ascii names? There
shouldn't be, which is why I'm curious.

I don't think you will have lost any data! There's probably just a bogus
group name or two in your newsrc.eld file which is preventing Gnus from
starting up. If you feel comfortable doing this, would you send me your
.newsrc.eld file off list?

Sorry for this train wreck...

Basil's explanations are correct, I'll just add that you've only got
one.newsrc.eld file, recording marks for all the groups you're
subscribed to, but each of your backends produces its own active file,
saying what groups it contains, and what the newest messages are. For
nntp you request it from the server. For nnml it lives on your computer
(I think it goes under (concat gnus-home-directory "News/")). For
nnimap, the server sends Gnus a list of groups and Gnus munges the list
into something that *looks* like an active file. Gnus knows if you have
new mail by comparing the active file information with your.newsrc.eld
information.

Sorry, I meant duplicate groups appearing in your *Group* buffer, not
your.newsrc.eld file.

Ok, I've applied the patch to emacs-27.0.50 and gnus opens the nnrss feeds
satisfactorily - as it does with my other newsgroups and the imap
emails. There are no errors or warnings at all. I did `make clean' and
deleted lisp/gnus/*.elc files before the final `make', so I may have
gone overboard in the build.

Best wishes,

Colin.

Yes, I have this weirdness under "Deleted Items".
On my web interface there is only the top-most group, with no subgroups
as "Greek Holidays". As for the subgroup name with the long hash
attached, I would never have created such a group name. it is an
artefact.

Hi Basil and Eric,

thanks a lot for these explanations.  I will see if I can make
suggestions against the Gnus manual to help people understand this
more easily.

OK, sounds like the problems reported here were fixed at the time, so
I'm closing this bug report.  If that's a mistake, please reopen.
