Using Windows ucrt mps emacs build from

https://github.com/kiennq/emacs-build/releases/tag/v31.319.20241101.0cb75cf



Since like two months or so, most notably package-el, but also other file
deleting operations like expiring eww cache, fails to delete files in
.emacs directory on Windows. The error message is "permission denied". I do
run emacs as the interactively logged in user. FWIW I start emacs from a
bash command line as runemacs.exe



Manually deleting files from within dired in the .emacs-directory works so
I do not think it is a permission issue.

bug#74202: Addendum: full error message

[Johann Höchtl]

[-- Attachment #1: Type: text/plain, Size: 413 bytes --]

The full error message is:

Error when expiring the cache: (permission-denied Removing directory
Permission denied c:/Users/HoechtlJ/OneDrive - WKO
Online/Dokumente/.emacs.d/url/cache/HoechtlJ/https/org/gnu/www)

The directory unfortunately contains blanks, so it's possibly not a
permission error at all but emacs actually trying to delete another
directory but the one for which the error message gets printed?

Thanks, but that site has local patches to Emacs, and two months is a
very long time.  It also uses UCRT, which is not really supported for
the Windows builds, as we have no one who'd agree to maintain such a
build and take care of any issues that arise with it.

So to investigate this issue someone with access to that build should
catch these errors in a debugger and show the details: which file
cannot be removed, what is the Windows error code when we try to
remove it, etc.

What is the Lisp code which triggers this error message?  IOW, please
show the Lisp code which "expires the cache".

Why would blanks in the directory name cause Emacs to try to delete a
different directory?  Emacs doesn't delete directories via the shell,
where this could be a problem, it deletes them by calling Windows
APIs.

Since this directory seems to be on OneDrive, I suspect that these are
not "normal" Windows files, but some kind of junction points or some
other filesystem wizardry that Emacs doesn't understand.  Please try
producing a standalone self-contained recipe for reproducing the
problem starting from "emacs -Q", preferably without installing any
ELPA packages.  Since the issue is with removing files from a
directory, presumably the problem has nothing to do with package.el
per se, but with basic file I/O, and so you should be able to find a
way of reproducing it by simply removing files from a directory,
perhaps if the directory is on OneDrive.

Dear Eli,

thank you for your response(s). I understand that this build is not
officially supported. Upon further investigation I think the culprit is
likely UCRT, as the directories are created without write permissions.
Former versions of Emacs, which used a different C runtime, created
directories with read/write permissions.

Therefore I will report the issue at the appropriate build site.

Best, Johann

Thanks, I'm therefore closing this bug.
