Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Hello,
I want to use the Gnus registry to use registry marks and store data as
described in (info "(gnus) Store arbitrary data"). Very often, these
things vanish after restarting Emacs or Gnus.
For example, I use M M i to mark some article "Important". I have
configured `gnus-summary-line-format' to show registry marks. Often,
after restarting, the mark is gone. Likewise, data stored with
`gnus-registry-set-id-key' gets lost, even when the according article
has a registry mark attached.
[BTW, there is a typo in (info "(gnus) Store arbitrary data"). It says
`gnus-registry-extra-entries-precious' would default to (marks) but it
defaults to (mark)]
My final goal is to implement a little Gnu Elpa package
"gnus-article-notes.el" that can be used to attach little text notes to
arbitrary articles. The package is already done, if you are interested,
I can send you the code. I have verified that registry marks get lost
independently of that package. I guess there is something wrong with
registry pruning. CC'ing Eric Abrahamsen who has recently worked in
this area.
TIA,
Michael.

There were some bugs with registry pruning and precious entries, but
we fixed those quite a while ago. If you're running Emacs master, you
should have the Gnus that incorporates those fixes. On the other hand,
what you say above about the docstring makes me wonder, as in Gnus
master it doesn't say it would default to (marks). You're not loading an
external Gnus installation, are you?

Yes, I think so, too. I have a normal recent Emacs master build. I
typically rebuild daily.

No, I'm not. In emacs master branch, "doc/misc/gnus.texi" says
"default this is just @code{(marks)} so the custom registry marks are"
in line 26197. Not for you?

Sorry, I was looking at the option docstring, not the manual. I'll fix
that typo.
But that was my only easy solution, unfortunately. You could examine the
results of:
(registry-collect-prune-candidates gnus-registry-db
(registry-size gnus-registry-db) nil)
To verify that it is returning candidates that should not be returned.
Unfortunately that function uses `cl-loop', which makes edebugging not
very helpful.
Shameless plug: I'm about to propose a new package called "gnus-mock",
which sets up a temporary/trashable/reproducible Gnus installation that
you can use for testing feature and hunting bugs, without endangering
your own Gnus data. That would be useful in this case. I might have it
done today.

Ok, I'll try that.

Yes, that's sounds exactly like the thing I wanted :-)

Ok, I managed to debug this.
The entry is indeed pruned. It looks like
Key: "<153...>"
Value: ((mark Important) (subject ...) ...)
In the `registry-collect-prune-candidates' method, the variable PRECIOUS
is bound to the list (gnorb-ids org-tags mark).
AFAIU, since PRECIOUS-P is defined as
(lambda (entry-key) (cdr (memq (car-safe entry-key) precious)))
and the symbol mark comes last in the PRECIOUS list, the `cdr' of the
`memq' call is nil. If I remove the `cdr' call, the entry isn't pruned
any more. I also don't get why that `cdr' is there. Or is my value of
PRECIOUS illegal?

Nice work! I have no idea why that `cdr' is in there, and as the value
is used as a boolean it seems totally superfluous. I don't use registry
marks, which is probably the reason I never noticed (I didn't write this
code).
I don't see any reason not to remove the `cdr', and will do so unless
someone objects cogently, soon.
Thanks,
Eric

Looks like the code has been like that from the beginning: ccd58722df
"Add lisp/gnus/registry.el.", Ted Zlatanov, Tue Apr 5 23:37:02 2011
introduces the file (it has been moved once since then), and the code is
already the same there.
I can only guess that the intention could have been to distinguish (mark) from
(mark SOMETHING): prune the first because the mark field is empty.
Anyway, seems it never worked like that.
Michael.

But what's even more frightening: The default value of
`gnus-registry-extra-entries-precious', (mark), always behaved like ()
and thus never worked as intended, so it seems that registry marks
always where broken with the defaults. Looks like nobody ever tried to
use them, or all people gave up without writing a bug report.
Should we even make a NEWS entry along the fix saying that the feature
can actually be used now?

I don't think very many people use the registry, or at least, they
aren't using it intentionally to store their own information.
> Should we even make a NEWS entry along the fix saying that the feature

I don't think so, bug fixes don't usually get a NEWS entry. But I can
say something on the gnus.general list.
Also, I really like the idea of using the registry to attach notes to
mails -- that's something I've intended for Gnorb for a while. If you'd
like to contribute that to Gnorb I'd be very happy to accept it, or
maybe it's something that could even go into the registry proper. Of
course, if you'd prefer to keep it a separate package that's fine too --
I'd install it!
Thanks,
Eric

I see you already did, and on the emacs-26 branch. Please in the
future ask about commits to the release branch.

Sorry about that -- it occurred to me I should have asked right after I

Some days ago I asked a question about the habits and expectations
regarding bug fixes, in particular for bugs that were not introduced by
the current release. Nobody disagreed that committing to the release is
just ok. So it is not? Why do you think people know what you expect?
(This is not a rant, I really just want to know what the rules and
expectations are.)

I wanted something really really simple, in particular, something that
is not linked to org. It's an approach different from Gnorb, but maybe
it would fit into Gnus, dunno. I attach what I have so far - feedback
welcome.

Ha, I see what you mean, most of the code is for displaying and editing
the notes. I did something similar in org-annotate[1] (which is pretty
similar in spirit to what you're doing here, but for org files), but
just realized that I don't use the popup for editing, only display.
Well, let's see if anyone is interested in a generalized solution!
BTW I just used `set-local-key' in my function -- I don't think it's
necessary to make a new local keymap for a single-use buffer.

Don't know that function - do you mean `local-set-key'? In this case I
must warn, citing the docstring of `local-set-key':

I did mean `local-set-key' and did not realize that's how it works!
Thanks for the tip.

In general, it is. But a bug fix should be safe enough to be eligible
for the release branch, and the "enough" part changes depending on the
state of the branch. Currently, since Emacs 26.1 was already
released, only very safe fixes are eligible, and I'd like to be part
of the decision loop regarding the safety of each proposed fix.
> Why do you think people know what you expect?
Because I said it many times here. The fact is, most people do ask.

But CONTRIBUTE tells something different. I have the feeling that some
people ask because they are lost, not because they know that it is
expected that they ask. Others just don't ask.
Anyway, if it works for you...but I think it would be better to have
some rules written down somewhere if we want to be attractive to new
contributors.

CONTRIBUTE's main audience is people who have no write access to the
Emacs repository, so what it says just tells them on what branch to
base the patches. The decision to which branch to push is then made
by someone who actually pushes the changes.
I'm okay with adding the request to ask about committing to the
release branch, but at the time I was under the impression that some
people didn't agree with such a policy, so I'm not sure the project as
a whole would like it carved in stone from here to eternity.
> I have the feeling that some people ask because they are lost, not
> because they know that it is expected that they ask.
That's not the reality. People explicitly ask _me_ whether it's okay
to push to the release branch; the exceptions are almost non-existent.

I'd put it in Elpa and then alert the list -- things tend to just
disappear if you post them without a permanent home.

Sorry for the bad news - but my registry marks are disappearing again
:-( Just after restarting Gnus they are gone.
I wanted to try with gnus-mock but it errors:

I tried to load the source of gnus-mock to get a more meaningful
backtrace but that also errors:

Ah, this was a question I had when I was first writing gnus-mock --
load-file-name was reliably present for all my tests, but they were only
on Linux. Can you tell me what system you're running? Presumably
there are better alternatives to load-file-name under different
circumstances.

Hey do let me know what system you're running! If I do:
1. emacs -Q
2. M-x load-file -> ~/.emacs.d/elpa/gnus-mock-0.4.2/gnus-mock.el
Then gnus-mock-data-dir is set correctly. I don't know what else might
be going wrong!

Thanks! Okay, it looks like I made a dumb assumption about how people
would be using this -- I assumed this package would only be used for
*developing* Gnus, and thus `gnus-mock-emacs-program' would always be
pointed at a "src/emacs" executable in a build tree. I don't even have
emacs installed as a package on my machine, and only ever run it from
one of the source directories. But of course that's not the code I wrote
-- by default it will find an installed version of emacs if you have
one, and then this default-directory setting will fail.
In the interim, you can set `gnus-mock-emacs-program' to point to an
emacs executable in a source tree checkout, and it ought to work fine. I
should probably change the code to require that, or else figure out how
to start up successfully from an installed emacs program.

Would it make sense to change the default of gnus-mock-emacs-program to
something like (expand-file-name "src/emacs" source-directory) or
similar?

Yes, that would probably work. But it still make assumptions about how
the user is working on emacs. Probably I should just default the option
to nil and ask users to always set it explicitly.

Ha, yes, I got distracted. Unfortunately I haven't been able to
reproduce so far. I start Gnus with this in the init file:
(setq gnus-registry-max-entries 10)
(gnus-registry-initialize)
(defalias 'gnus-user-format-function-M 'gnus-registry-article-marks-to-chars)
(setq gnus-summary-line-format "%uM%U%R%z%I%(%[%4L: %-23,23f%]%) %s\n")
Mark some articles as Important or ToDo, stop and restart Gnus, and
everything is still present. I opened a bunch of other groups, so that
pruning (if that were the issue) would have dumped the entries with the
marks, but they are kept as expected.
Anything other way to narrow this down?

Wouldn't that be the worst default since people are expected to use
emacs -Q to start gnus-mock?

Hmm, currently I can't reproduce either. I'll start using registry
marks again in real life and see if it works reliable now.
One little thing that bothers me however: when I hit M M i, or when I
remove a mark with M M I, the article line gets doubled: one line has
the mark, and the other doesn't. Do you see that too?

Michael.

People are expected to use `gnus-mock-start' to start it, which does
"emacs -Q" internally. The only requirement is that the emacs be run
from a build directory, and not an installation.

Whoa, definitely not, and that's not how it's supposed to work. I wonder
what could cause that... Do you have
`gnus-summary-display-while-building' set to anything?
Oh, I remember you've got some advice on message limiting? I forget
what, exactly. Maybe try disabling that and see if it has anything to do
with it?

I tried it from my normal Emacs session and got this:
Debugger entered--Lisp error: (buffer-read-only #<buffer .newsrc.eld>)
replace-match("/tmp/emacs-gnus-mock-738lXO" t)
gnus-mock-start()
funcall-interactively(gnus-mock-start)
call-interactively(gnus-mock-start record nil)
command-execute(gnus-mock-start record)
Is that because it is an installed Emacs, or something else? Should I
investigate?
Thanks,
Michael.

I currently have no such advices enabled afaict.
How can I debug this - where is the old article line supposed to be
removed? I see that line duplication happens in
`gnus-summary-update-article', but it's quite complex.
Thanks,
Michael.

Man, who would have guessed this would be so difficult... I have no idea
why a data file that ships with the package would become read-only.
I suppose I could wrap that in `inhibit-read-only', but if it's read
only for a reason that will only fail later down the line. Can you check
two things, and then I'll give up for now?
1. Put a breakpoint or edebug or otherwise slow the function down, and
after the data directory has been copied to /tmp, make sure that it
belongs to your user and you have the right permissions?
2. Try this version of gnus-mock-start and see if it works:

It amuses me to see the verb "reproduce" used intransitively in this
context, because what that means is that you are unable to produce
offspring. I don't think that's what you meant ;-).
With a bug, the thing to say is "I can't reproduce it."
Of course, people understand anyway.

When I delete the (buffer-read-only . t) association from
`so-long-variable-overrides' the problem is fixed. The only so-long
thing in my init file is (global-so-long-mode 1). Since some people
will do this and the default behavior breaks gnus-mock I guess you will
want to handle this somehow.
Regards,
Michael.

I don't recall, but I guess it wasn't what I wanted to say. I begin to
wonder why this kind of thing happens only to me.
But this probably doesn't belong in this bug's thread - should I open a
new one?

Phil, what's your opinion about this? gnus-mock.el wants to edit a file
it has opened with find-file-noselect, which is a common thing to do.
But it fails for me because I have enabled global-so-long-mode in my
init file and it makes the buffer read-only. This is quite surprising
because the buffer is only used internally by gnus-mock. Could so-long
be a bit smarter here?
TIA,
Michael.

Well it seems pretty odd that a package meant for handling single-line
files would prevent us from editing a file at all. I don't even see why
so-long would even be kicking in, here -- the newsrc.eld template isn't
one long line!
I guess I can do the inhibit-read-only thing, but if I've got to
anticipate something like this happening, it's hard to guess what else I
might need to defend against...

Sure, absolutely. I've never had very much confidence in how gnus-mock
handles the "find the load file and nearby directories" process, so it's
good to have some real-world feedback.

Wait, just to be sure I understand what's happening here: does the
default option value get evaluated at compile time, or load time, and is
there a difference?

At load time.

I think that only difference to before is that you get a useful behavior
(works as expected) when you open the file and load the buffer (tested).
I didn't think long about it but instead I had a look how other packages
handle the case.

This sounds very much like:
https://savannah.nongnu.org/bugs/?56835
I have committed[1] a fix for that in my WIP branch here:
https://git.savannah.nongnu.org/cgit/so-long.git/tree/?h=wip
Could you test that and let me know if it fixes the issue for you?
If so, I'll go ahead and merge the changes into Emacs. (I hadn't
merged it to Emacs yet simply because its a notable change to how
so-long has operated in the past; but I'm mostly sure it's going
to be fine.)
The documentation regarding this is as follows:
;; * Buffers which are not displayed in a window
;; ---------------------------------------------
;; When a file with long lines is visited and the buffer is not
;; displayed right away, it may be that it is not intended to be
;; displayed at all, and that it has instead been visited for
;; behind-the-scenes processing by some library. Invisible
;; buffers do not typically not cause performance issues, and it
;; might be surprising to the other library if such a buffer were
;; manipulated by `so-long'; so in these situations the
;; `so-long-invisible-buffer-function' value is called instead.
;; By default this arranges for `so-long' to be invoked on the
;; buffer if and when it is displayed, but not otherwise. This
;; is actually the normal way for `so-long' to be called -- even
;; when a visited file is displayed "right away", it is normal
;; for the buffer to be invisible when `global-so-long-mode'
;; processes it, and the gap between "arranging to call" and
;; "calling" `so-long' is simply extremely brief.

Do you really want this to be nil when the file buffer is evaluated?
(defconst gnus-mock-data-dir
(when load-file-name
(file-name-as-directory (expand-file-name
"data"
(file-name-directory load-file-name))))
"Source directory for Gnus mock data.")
Then again I need additional work when loading the source to debug. You
could at least accept `default-directory' when it contains a "data"
named directory, or query for a directory with a useful default instead
of barfing when gnus-mock-start is called. With other words: what I get
now is just another kind of barfing, no real improvement.

Thanks - all that I read sounds like your branch should fix our problem.
But how can I clone your repo?
bash-5.0:micha:today$ git clone https://git.savannah.nongnu.org/cgit/so-long
Cloning into 'so-long'...
fatal: repository 'https://git.savannah.nongnu.org/cgit/so-long/' not
found
BTW, you can also just send me a checkout privately.

Oops, I didn't realize that default-directory would be set to the
containing directory at load time -- I assumed its chances of finding
the "data" directory correctly were essentially nil. I'll use your
version now...

Well damn. And we're coming up on Emacs 27.1, too... I've never seen
this before -- would you mind sending all your registry-related config
(off-list, if necessary), and anything else you might think is relevant,
and I'll try to reproduce?

Ok, I debugged it. FWIW I recently learned that "I'll try to reproduce"
has a meaning that I didn't expect: you need to say "I'll try to
reproduce it" or else Stallman might show up and laugh at you (it
happened to me).
Ok: I have only (gnus-registry-initialize) in my init file. And this is
already broken:
"gnus-registry.el" initializes gnus-registry-db like this:
(defvar gnus-registry-db (gnus-registry-make-db)
"The article registry by Message ID. See `registry-db'.")
and in `gnus-registry-load' the
(null (eieio-object-p gnus-registry-db))
always fails so unless you call `gnus-registry-load' with the force arg
you always start with an empty db.

Oh I see, when the file is loaded the variable is already initialized to
an (unloaded) registry object, so it never actually loads/reads its
persistence file.
Except that it certainly seems to! I've never seen this cause a problem,
and no one calls `gnus-registry-load' with the FORCE argument, so if
this was an issue, it seems like it would fail for everyone
immediately...
In fact, I don't know the defvar is initialized to anything at all.
For eieio-persistent objects, you're not supposed to make-instance
yourself, you're supposed to use `eieio-persistent-read' (which is what
loading is supposed to do).
Dunno why it works, though...

Okay, I mostly slept on the plane. But...
One missing piece of the puzzle: the Gnus startup process runs
`gnus-clear-system', which runs `gnus-shutdown', and the registry has a
shutdown routine that sets `gnus-registry-db' to nil. Starting up Gnus
essentially first shuts it down.
But that still doesn't completely explain why this works. Say a user
starts Gnus cold, and only loads gnus-registry.el via an autoloaded call
to `gnus-registry-initialize' in the init file. The shutdowns run before
the init file is loaded, meaning gnus-registry.el hasn't been loaded,
meaning it hasn't had a chance to add its registry-related shutdown yet.
So we should still be loading the registry with an already-initialized
`gnus-registry-db', and overwriting the user's existing data.
Obviously the code as it stands should be changed: either I should find
another way of preventing double loading, or the defvar shouldn't
initialize the database to anything (I prefer this latter). But it's
still a mystery to me...

But that shouldn't be hard to find out with the help of edebug, variable
watchers, etc. - right?
BTW, are you sure that the behavior you see is seen by anyone else?
Could it be that it works just for you because of your setup?

Initializing with an empty database cries for this sort of problem.
This should only be done when loading fails because the save file
doesn't exist. Then the user should be informed that a new empty
database is created.
BTW, what's so problematic with avoiding repeated loading? Can't you
just use a bool var to remember?

No, I just didn't have time between waking up and landing. I'm on a

I'd be awfully surprised if it only worked for me -- I'd think we would
have seen bug reports by now. I still blame your usage of debbugs-gnu :)

Yes, I agree that initializing to an empty database is a bad idea. All
the mechanisms are already in place for detecting when no database has
been created, and making a new one -- there's no reason to hang an empty
database on there. I'd still like to know exactly what's going on,
though.

I thought that the `eieio-object-p' check WAS the equivalent of the
"bool var". I hadn't actually seen that the defvar was initialized like
that.
Anyway, I don't want to make another sloppy mistake. But I do think just
leaving the defvar at nil and getting rid of `gnus-registry-make-db'
will end up being the solution.

My impressions is: some people may have tried using the registry, but
most of them gave up, and nearly nobody is using it.

I don't. AFAICT the issue happens with (featurep 'debbugs-gnu) ==> nil
all the time.

No, I didn't really mean that...
Would you try the attached patch? It leaves gnus-registry-db at nil to
start with, and also removes the root of the double-loading (which was a
problem only because it can potentially be very slow).

Seems to work so far, tested for a while (also once quickly with
debbugs-gnu ;-)
So you now (re-)load the db repeatedly and unconditionally?

Oh good :)
> So you now (re-)load the db repeatedly and unconditionally?
No: unconditionally but only once. I fixed it (I hope) closer to the
root of the problem: calling `gnus-registry-initialize' used to load
once unconditionally, then add the load function to
`gnus-read-newsrc-hook', which would load a second time at startup. Now
`gnus-registry-initialize' checks whether Gnus has already been started
and does one or the other, not both.
I'll test a bit more and then push, this should go into 27.1.

For me it's reloaded for every M-x gnus (but only once per gnus
invocation). I'm not sure if that's what you meant.

Yes, that's what I meant. Every invocation of `gnus' first unloads everything and then reloads it, and the registry is likewise unloaded and reloaded. That seemed like TRT to me.

It is! Pace bugs I may have introduced, I feel like this is the right
approach.
The only integration that's lacking is auto save (which doesn't work
well with eieio-persistent). If you quit Gnus without saving, your
intermediate state goes into the dribble file, and you can choose to
load that again later. But the registry doesn't work with the dribble
file (it would be a medium amount of work to make that happen) so you'd
lose any edits to the registry made since the last save.

Another difference is that when you quit the summary with -Q, registry
marks are saved anyway. But I like that :-)

Yes, the registry actions are immediate, while most of the other summary
operations are "apply on exit". I don't think that matters, though --
the "apply on exit" actions are only related to manipulating marks,
which the registry doesn't care about. The immediate actions -- delete,
move, expire, spool, etc -- the registry already watches.

I'll do it now. The first time I applied it on my own setup it told me
it was reindexing the registry, which made me nervous again, but it only
did that once, and didn't lose any data. What I think actually happened
is that the fixup-registry routines ran and updated the :tracked slot
and saved it properly, which might not have been happening before.
Thanks for your continued patience with these problems. Don't
give up on the registry!

Ok, I won't.
I wanted now to add a hack to my config to save a backup of the registry
save file every time it is saved.
But now I wonder if that would not be a good idea anyway? I think it
could be done like in `gnus-save-newsrc-file' (look for
`backup-buffer'). Does that make sense?
I think I would then advice `gnus-registry-save' so that lots of backups
are kept, in a separate folder, to prevent future data loss.
Regards,
Michael.

There are plenty of places where you could do a backup. The registry
itself is saved on the `gnus-save-newsrc-hook', that's a fine spot.
I was going to say you could add a method to `eieio-persistent-save',
maybe an :after method, and do it there, but now I wonder if you might
get into some sort of recursive loop, since you'd want to use
`eieio-persistent-save' in there, as well. I was thinking you should do
it at the lowest level possible, but this might actually be too low.
Part of the reason for "going low" is that there are routines for making
sure that non-ascii group names are mangled properly before saving.
Ooh, I just realized -- Lars wasn't into me properly encoding Gnus group
names in the .newsrc.eld file, but there's no reason the registry has to
be under that restriction, as the data is meant to be transient at some
level. I could leave the decoding routines in place and get rid of the encoders.
Anyway! That's a different question.

AFAIU that's not necessary or what I plan. When `backup-buffer' creates
a backup for a file (named by buffer-file-name) it basically makes a
copy of the already existing file (and before any new contents are
saved) as newest backup. Making a backup of the old version of the
registry save file is sufficient.

Oh, of course! Well in that case an :after method on
`eieio-persistent-save' might be just the thing.

I'll use this for now - works so far:
#+begin_src emacs-lisp
(setf (alist-get (regexp-quote ".gnus.registry.eieio") file-name-handler-alist)
(defun my-gnus-registry-save-file-handler (operation &rest args)

(let ((inhibit-file-name-handlers
(cons 'my-gnus-registry-save-file-handler
inhibit-file-name-handlers))
(inhibit-file-name-operation operation))
(apply operation args))))
#+end_src

Huh. Seems like a fair amount of work, but it's certainly low level!
Nice to have it integrated into all of Emacs' regular save-file

Caveat: if anybody wants to use this: please specify a `testfn' argument
(e.g. `equal') of `alist-get' to prevent repeated pushing to
`file-name-handler-alist' when the code is loaded repeatedly (which is
the case for the gnus init file AFAIK).
Michael.
