Subject: [feature/native-comp] emacs keeps running 100% of CPU
Date: Sun, 10 Jan 2021 00:44:44 +0100

I noticed that when launching emacs on linux (debian buster),
it keeps on running 100% of the CPU and seems to gradually eat all
memory, approximately 1-2% every minute.

It seems related to native compiling. In the 
*Async-native-compile-log* I read :

<=============================>
Compiling 
/home/edouard/.emacs.d/elpa/color-theme-sanityinc-solarized-20200805.603/color-theme-sanityinc-solarized.el...

In color-theme-sanityinc-solarized:
color-theme-sanityinc-solarized.el:850:14: Warning: assignment to 
free
   variable ‘ansi-color-names-vector’
color-theme-sanityinc-solarized.el:851:14: Warning: assignment to 
free
   variable ‘ansi-color-faces-vector’

In end of data:
color-theme-sanityinc-solarized.el:878:1: Warning: the function
   ‘color-theme-install’ is not known to be defined.
<============================>

Furthermore "ps x" gives :
1395 pts/1    Rsl+   7:51 /usr/local/bin/emacs --batch -l 
/tmp/emacs-async-comp-color-theme-sanityinc-solarized-ENplTN.el

If I kill this process or close the *Async-native-compile-log, 
then this disappears.

I do not understand what is the trouble with this package. The 
native compilation of
this package seems to be endless.

But this could be related to the previous bug "excessive memory 
..." as I use the
same package theme on windows 10.

I see a similar issue with sanityinc-tomorrow.el, the compilation is way
slower than any other one but it completes eventually.  I guess is the
same issue you see and with sufficient RAM also sanityinc-solarized
should complete.

In case of of sanityinc-tomorrow I think is because of
`color-theme-sanityinc-tomorrow'.  This is a single function that after
macro expansion becomes enormous.

We need to make the compiler robust against these corner cases, I'll
have a look this week into adding some logic for that.

Thanks

I have waited for approximately one hour and until linux became 
totally unresponsive, I had to reboot.

I am not 100% sure it is because of emacs compiling the color 
theme package and eating all memory,
but I never had such a crash on linux since I own this laptop and 
I had exactly the same crash on
windows 10 with emacs native-comp eating all memory.

So most probably, my previous bug is related to that. I could try 
another theme and see if this still happens.

Also, is there a way to prevent emacs native-comp to compile some 
packages, some kind
of blacklist. I would prefer at the moment because I am used to 
this color theme.

Do you think there may be a noticeable difference on emacs's 
performance between a
color theme natively compiled (*eln) or just byte compiled (*elc)

Maybe we should have a "no-native-compile" cookie for these cases.
After all, compiling a theme will not really speed up anything
important, right?

This is more or less what I advocated with a native compile 
blacklist.

At the moment, it would help me if it is possible to toggle native 
compilation.
In my config file there is :

(setq package-native-compile t)

If I set it to nil, does it mean that, on startup, emacs will not 
try to natively compile
any packages ?

Answering to my own question, it seems that no. Is there an emacs 
command to kill the
native compiling process ? It seems that closing the log buffer 
has this effect, but there
is probably a better way.

Right, these are the classical symptoms of a system swapping for
insufficient physical memory (or excessive mem usage by a program :)

Yes, `comp-deferred-compilation-deny-list'.

I don't think so.

Agreed, that's a good idea.

At the moment similar mechanisms are:

- Declare a function with (declare (speed -1)) will include the
  function in the .eln but in byte-code form.

- Have comp-speed to -1 as file variable in the source file should
  produce an eln containing only byte-code functions.

But yeah, a dedicated cookie is better because there's no point of
producing the .eln file at all for cases like this.

Thanks ! In fact I just discovered this settings as you answered 
me and

(require 'comp)
(setq comp-deferred-compilation-deny-list '("color-theme-*"))

in my init file does the job.

Probably, my previous bug report "Excessive memory ..." was due to 
this package
trying to be natively compiled. I will try the 
"comp-deferred-compilation-deny-list"
setting on windows 10 so as to be sure there is nothing more.

[Message part 1 (text/plain, inline)]

Tried on windows.

Indeed, with previous settings in my init file, I do not see anymore emacs
eating all memory, currently it remains at ~150Mo while idle.

The only trouble is that some packages fail to be natively compiled as
"smart-mode-line" with the same error :
Debugger entered--Lisp error: (wrong-number-of-arguments (3 . 4) 2)

I blacklisted this package too.

Details of the error follows, I presume this is a compatibility problem
with emacs 28.0.50 ?

Right so I'll merge with bug#45705.

Hi Édouard,

with 0ffb3dfaa4 I'm now able to compile
color-theme-sanityinc-solarized.el.

Could you check works for you too?

Thanks

As for me is working and no feedback was provided I'm closing this.

Happy to re-open in case.

Thanks!
