bug#46972: 28.0.50; [feature/native-comp] Emacs locks itself during native compilation because of permission denied

[Matt M]

I'm on windows using latest native compilation. I noticed that when doing

doom sync (I use Doom emacs) it would hang on the native compilation

step. I looked at the opened emacs processes in the task manager

during this bug to try to find a file with which I could make the bug

trigger again. In the task manager I see that about 10 emacs processes

are stuck on 10 files.

 

Using this file: https://pastebin.com/z4wLheXa as

emacs-async-comp-ox-ascii.el, I call the following command:

 

emacs -Q --batch -l c:/Users/Matt/emacs-async-comp-ox-ascii.el

> Compiling c:/Users/Matt/.emacs.d/.local/straight/build-28.0.50/org-mode/ox-ascii.el...

 

It never finishes. If I interrupt the process I get the following

backtrace:

 

Debugger entered--Lisp error: (file-error "Removing old name" "Permission denied" "c:/Users/Matt/.emacs.d/.local/cache/eln/28.0.50-4c...")

  kill-emacs(t)

  command-line()

  normal-top-level()

 

Removing old name: Permission denied, c:/Users/Matt/.emacs.d/.local/cache/eln/28.0.50-4c6fa13f/ox-ascii-dcca1ba0-825ea35cp6iXUJ.eln.old

Debugger entered--Lisp error: (file-error "Removing old name" "Permission denied" "c:/Users/Matt/.emacs.d/.local/cache/eln/28.0.50-4c...")

  command-error-default-function((file-error "Removing old name" "Permission denied" "c:/Users/Matt/.emacs.d/.local/cache/eln/28.0.50-4c...") "" debug)

  apply(command-error-default-function ((file-error "Removing old name" "Permission denied" "c:/Users/Matt/.emacs.d/.local/cache/eln/28.0.50-4c...") "" debug))

  #f(advice-wrapper :after command-error-default-function help-command-error-confusable-suggestions)((file-error "Removing old name" "Permission denied" "c:/Users/Matt/.emacs.d/.local/cache/eln/28.0.50-4c...") "" debug)

 

It renamed a file from file.eln to file.eln.old, then tries to delete

the file.eln.old but gets a Permission denied error.

 

If I start the same command again without interrupting, and try to

delete the file.eln.old manually, I get the error:

Can't remove file because the file is opened in emacs.exe

 

And the only emacs.exe process runnin on the computer is the one doing

the native compilation, the one which created the file.eln.old.

 

So that seems to indicate that the emacs process that renames the file

doesn't have the permission to remove the same file because of it being

opened in itself.
