bug#63871: 29.0.91; JIT native comp triggered to compile loaddefs repeatedly on require

bug#63871: 29.0.91; JIT native comp triggered to compile loaddefs repeatedly on require

[Jimmy Yuen Ho Wong]

Reproduction:

1. emacs -q -nsl --eval="(require 'cl-lib)"
2. C-x b TAB
3. Select *Async-native-compile-log*
4. The following is printed

```emacs-lisp
Compiling /opt/local/share/emacs/29.0.91/lisp/emacs-lisp/cl-loaddefs.el.gz...
uncompressing cl-loaddefs.el.gz...
uncompressing cl-loaddefs.el.gz...done
Compilation finished.
```

Expectation:

This behavior is observed when any packages in ~/.emacs.d/elpa/
autoloads and require cl-lib, org or tramp as well.

The simple act of requiring a built-in Emacs package should not trigger
a JIT native compilation on an Emacs installation built with
`--with-native-compilation=aot`.

And it doesn't.  cl-loaddefs has the "no-native-compile: t" thingy in
the file-local variables, so the native-compilation does nothing.

So I don't see any bug here, and I'm closing this bug.

bug#63871: 29.0.91; JIT native comp triggered to compile loaddefs repeatedly on require

The problem is not that it does something when it compiles, the problem is it should not have triggered a compilation at all and pops up a buffer. This messes up the buffer order when restoring a session with desktop mode on restart.

bug#63871: 29.0.91; JIT native comp triggered to compile loaddefs repeatedly on require

[Jimmy Wong]

[-- Attachment #1: Type: text/plain, Size: 1707 bytes --]

The problem is this:

1. There’s no-native-compile:r set in the file, so a eln file was never produced.
2. nativecomp does not know which file should not be compiled until it opens the file
3. Whenever a require is encountered, nativecomp can’t find its eln, doesn’t know it can’t be compiled until it reads the file, and it can’t read the file until it unzips the file.
4. This unnecessary work is done every time any package requires one of these packages that cannot be compiled, again and again, generating an extra buffer that mess up the buffer orders in the buffer list.

When there’s a package or a file that should not be natively compiled, there should be a global blacklist variable that controls that instead of relying on a file local variable in order to short circuit this behavior.

??? Why?  Loading a package could legitimately load other packages.
Emacs worked like that since about forever.  What is special in this
particular case?

And what do you mean by "pops up a buffer"?  When I reproduce your
recipe, no buffer is popped on display.

Messes up how?

And what do you expect from the buffer order when you restart a
session using desktop.el?

I expect the buffer orders in the buffer list to be restored when desktop mode restores a session, not have an async native compile log buffer inserted at the top so I can quickly switch to the second to last buffer I was working on before the restart.

Sorry, I don't see any problem.  This is normal and expected behavior,
and one more buffer cannot possibly be a problem.  Especially since
that buffer will be created soon enough anyway, once you load some
previously-uncompiled package.

I fail to understand why another buffer could be a problem.

I don't see any bug here.

We decided against that.  (A blacklist would unnecessarily complicate
any changes in our decisions which file to compile and which not to
compile.)  We think what we have now is perfectly fine.  I still don't
understand why you see a problem there.  It's perhaps unexpected, but
that's all.  It's a buffer users normally don't need to look into.
The alternatives are worse, sometimes much worse.

Unless you’ve set package-native-compile to t so you’ll rarely see this buffer. Installing new packages is not a frequent operation in normal Emacs usage, and when a user installs a new package and loads it, he’ll expect that buffer, not when simply having a package that requires that a package.

This expectation is incorrect.  desktop.el doesn't (and cannot)
promise that no new buffers will be created as part of restoring the
session.

If this gets in the way of some of your workflows, you can easily
write some Lisp for your init file, which will bury this buffer.

I’m not entirely sure why but fine. How do I configure Emacs in such a way that whenever this buffer is created, it is buried?

I still don't see how it matters.  Emacs generates such buffers in
many places, and it never is a or should be a problem.

Add a call to bury-buffer to the end of your init file.

Thanks. I ended up advising get-buffer-create instead as I don’t know how to add a hook to buffer-list-update-hook and not run into an infinite loop.

My suggestion would be to add this function to
desktop-after-read-hook.  Did you try that?

Thanks, I’m aware of that hook. I just always wanted it to be buried whenever it is created. I suspect this perhaps can be put into nativecomp as an enhancement.
