Why Emacs is echoing message for each installed Emacs package while startup

Why Emacs is echoing message for each installed Emacs package while startup

For each Emacs package I have installed, Emacs echoes "Loading
/gnu/store/...-emacs-.../...-autoloads.el" while startup.  This is very
annoying.  The reason is probably the function:

(defun guix-emacs-autoload-packages ()
  "Autoload Emacs packages found in EMACSLOADPATH.

'Autoload' means to load the 'autoloads' files matching
`guix-emacs-autoloads-regexp'."
  (interactive)
  (let ((autoloads (mapcan #'guix-emacs-find-autoloads
                           (guix-emacs--non-core-load-path))))
    (mapc (lambda (f)
            (load f 'noerror))  ;; This should be (load f 'noerror 'nomessage)
          autoloads)))

And also I wonder why Guix loads each autoloads file.  Can't it merge
(concat) all autoloads into one file while making the profile and then
load it afterwards?  This would probably save a little time.  package.el
can do this (see "package-quickstart-file" variable), so Guix should be
able to do this too.

Gonna speculate here a bit since I'm not sure if this pattern exists in
Elisp land, but I've certainly seen (and written) programs that
required to be run from a specific place, usually from next to other
submodules in the same package. If you were to concatenate (or even
just move) such a file, it would break, possibly silently.
You can't even rename a program and be sure that it will have the same
behaviour, see busybox for an example of this. It's a single binary
that checks what name it's run under and then acts like that executable.

Yes, this may be a problem for ordinary Emacs Lisp file.  But I'm
talking about autoloads.  It is a special file that defines autoloaded
functions.  Calling autoloaded functions will automatically load the
file containing the actual definition.  Autoloads files should not
depend on there names, and if they does its probably a bug.  All
autoloads files are needed to load at runtime, so concatenating all of
them should probably be a good idea.  Emacs builtin package manager
"package.el" and third party purely-functional package manager
"straight.el" both support merging the autoloads into one file.

But load many autoloads files is not a big problem, the main problem is
the messages "Loading...", "Loading...", "Loading..."...

Why is it a “problem”?  All these messages are inside the buffer
*Messages*, designed for collecting all messages.

Could you explain why you consider it is the « main problem »?

Because those message appear in echo area during startup, which is very
annoying to me.  As far as I know, no Emacs package manager does this.

No Emacs package manager does that indeed, but Guix manages packages in
a unique way too!

Take a look at /gnu/store/[hash]-emacs/share/emacs/site-lisp/ to
understand how Guix loads emacs packages.

Yeah, it's unique because it shows the same "Loading..." messages every
time I run Emacs.

Yes, I know there is a file named "guix-emacs.el" which defines the
"guix-emacs-autoload-packages" function, which is the culprit for the
"Loading" messages.  I can't understand the reason of these messages,
the user should know what he/she has installed, so there is no need to
tell that every time Emacs is started.

Perhaps I agree with you.  It would be trivial to send a patch, I'm just
not sure if it would be met with acceptance :)

I understand.  Although, in my case, it is too fast to be annoying.  How
many Emacs packages do you have in your profiles?

Right now, only one, because I use package.el.  But I'm planning to move
to Guix.

I used to have more than hundred Emacs packages managed by Guix.  But
the startup time was more than 5 seconds.  Then to switched package.el,
and the startup time decreased to less than 1.5 seconds.  I'm not sure
why this happened, but I think the cause is maybe too many "redisplay"s
due to many loading messages during startup.

Well, I do not know.  Hum, I do not have more than hundred,

--8<---------------cut here---------------start------------->8---
$ guix package -p ~/.config/guix/profiles/emacs/emacs -I | grep emacs | wc -l
43
--8<---------------cut here---------------end--------------->8---

but it does not takes so long:

--8<---------------cut here---------------start------------->8---
$ time emacs -f kill-emacs

real    0m1.682s
user    0m1.279s
sys     0m0.241s
--8<---------------cut here---------------end--------------->8---

which looks similar to,

        M-x emacs-init-time
        1.727791789 seconds

therefore, I am surprised by your timings.  For instance,

--8<---------------cut here---------------start------------->8---
$ guix shell emacs $(guix package -A | grep ^emacs- | cut -f1 | head -200)
[env]$ time emacs -nw -q -f kill-emacs

real    0m2.368s
user    0m2.037s
sys     0m0.309s
--8<---------------cut here---------------end--------------->8---


Well, I do not know if ’with-eval-after-load’ is enough for somehow
allowing lazy loading.  Hum, I am not convinced that the ’redisplay’ is
the issue but instead, yeah maybe walking all the files requires some
filesystem IO and yeah maybe one unique big concatenated autoload file
would improve the situation.


Do you use ’use-package’ or something similar for your config?

The timing maybe wrong, because it is more a year old (and I didn't
measure).  I was new to Emacs Lisp (I used Doom before), and my init.el
was messy.  So maybe the init file had something in it that was
responsible for slow startup when the packages managed by Guix.

Loading many autoloads files isn't a big deal for me, I don't use that
optimization.  With `package-quickstart' set to t, my init time is only
0.1 seconds faster, which I don't care.

Yeah, I use `leaf'.

Well, if you are able to time the two setups: the one using package.el
and ’leaf’ and the other one using Guix (and probably replacing the
lines «:ensure :package :feather :straight :el-get» to use instead the
Emacs packages installed by Guix).

It could be informing about the potential gap.

Yeah.  That's really a good idea.  But unfortunately my Emacs init time
isn't stable after the Emacs 28 upgrade (without native compilation).
Sometimes it is as long as 4 seconds and sometimes only a fraction of
second.  Even if I a calculate an average, that won't be reliable.  I
have no idea why this is happening now, maybe I'll try investigate it
later.  I don't have much problem with this random startup time, as I
don't restart Emacs much (as the time of writing, emacs-uptime says
"5 days, 20 hours, 56 minutes, 26 seconds").

But, why is the message is shown?  Can someone remove it?  It would
probably be better that I myself clone the repo, fix it and send the
patch, but my hard disk space isn't allowing me to do that.  Is it
possible disable that message by modifing any Guix configuration file?

Hi Akib Azmain Turja,

It's not possible to disable the messages by modifying Guix configs.

I'm attaching a patch below.  Would you please send it to the Guix team
and make your argument?  Thank you.

Re: Why Emacs is echoing message for each installed Emacs package while startup

Hi!  I reply below:

Did you send the patch?  I have searched debbugs and have not found any
such submission.  I care because:

1. It significantly pollutes the *Messages* buffer, which can mask
   important warnings such as when Emacs loads a .elc byte compiled file
   that is older than its source code.
2. For people who byte-compile Elisp files from a Makefile, these
   messages causes significant pollution, masking byte-compilation warnings.
3. For people who use the nativecomp feature (from a guix channel),
   the native compilation of *each* Emacs package yields loading messages
   for *every* Guix-installed Emacs package, resulting in O(n^2) growth.

Thanks for reminding.  I forgot it completely, because the only Emacs
package I have currently installed with Guix is emacs-vterm, because
Guix doesn't work with the Emacs I compiled myself.  I have attached the
patch to this message and CCed to guix-patches.

CC guix-patches, for each Emacs package I have installed, Emacs echoes
"Loading /gnu/store/...-emacs-.../...-autoloads.el" while startup.  I
have attached a patch fixing it (thanks to "André A. Gomes
<andremegafone@gmail.com>" for preparing it).

Did I really sent the patch?  Looks like I forgot to attach the patch
and CC guix-patches.  :-/

There were timings made in the past when considering using the builtin
package.el to take care of some of the things we do, but it's much more
code than what we have and is unsurprisingly a bit slower.  If you look
at the guix-emacs.el file that takes care of autoloads discovery you'll
see there's really not much to it, if fits all under 100 lines of code.

Like Simon, I do not see why the autoloads-related messages are a
problem; they only occur when starting Emacs from scratch.  If you have
so many packages that the loading time or loading messages bothers you,
you may want to consider running Emacs as a server and connecting to it
via emacsclient; that way you load it once when you login to your
session for example and that's it.

For what it's worth, the messages are not printed by that custom Guix
Elisp code explicitly but by the Emacs function `load', on line 59 of
guix-emacs.el: (load f 'noerror).  If it really bothers you could change
it to:

(load f 'noerror 'nomessage)

Hope that helps,

Maxim

The messages also appear when viewing the *Async-native-compile-log* when Emacs is native compiling packages. And the all of the "loading packages" messages are repeated before /each/ package that is compiled.

That's not with the Emacs in Guix I guess, since we do not yet have
native compilation enabled.  But it seems like the problem here is not
the printing of the messages, but why when natively compiling packages
it would cause all the packages to be reloaded for each package... which
is crazy.

It's via a Guix channel for nativecomp Emacs: <https://github.com/flatwhatson/guix-channel> .

It only seems to be the packages installed via Guix though.

But why Emacs isn't built with native compilation support?  Any
technical issue or just someone hasn't done it yet?
