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

Hi,

I recently encountered an error, No package in XXX, when using the
package-install-file function in the latest Emacs snapshot. This function
was working correctly as of May 5, 2025, but started failing sometime after
May 8, 2025. I suspect there may have been a breaking change introduced.

This issue only affects the snapshot build—my CI tests cover Emacs versions
26.3, 27.2, 28.2, 29.4, 30.1, and the snapshot, and all versions except the
snapshot pass. You can view the test results here:
https://github.com/emacs-eask/cli/actions/runs/14904371642.

Thanks,
Jen-Chieh Shen

Philip, could you please take a look at this issue?

Can you elaborate what the tests are doing?  package-install-file works
fine for me on my end.

Hi, Philip.

The error was covered by my error message. After going one level deep, the
real error message is `Package lacks a file header `.
It occurred with the following code, not `package-install-file` (sorry for
the confusion).

``elisp
(with-temp-buffer
  (dired path)
  (ignore-errors (package-dir-info)))  ; error occurred this line
```

The test package I'm trying to install is located at
https://github.com/emacs-eask/cli/tree/master/test/jest/install/foo-mode.

Thanks!

Right, I was expecting something like this.  We recently added a change
that allows marking files in Dired and having `package-dir-info' respect
this by only considering these files IF the current buffer is in
dired-mode /and/ the Dired buffer has marked files.  What I cannot
deduce from this snippet, is if the Dired buffer at PATH was previously
opened or had any marked files in it.  Could you check that
(dired-get-marked-files) returns nil or call (dired-unmark-all-marks)
before invoking `package-dir-info`?

It wasn't previously opened.

(dired-unmark-all-marks)
> before invoking `package-dir-info`?

(dired-get-marked-files) doesn't return nil. I tried using
(dired-unmark-all-marks),
but (dired-get-marked-files) still returns the file—in this case, the path
to the Eask file.

The latest test code:

```elisp
(with-temp-buffer
  (dired path)
  (dired-unmark-all-marks)
  (eask--unsilent
    (message "? %s" (dired-get-marked-files))  ; This returns the Eask-file
path for some reason.
    (eask-ignore-errors-silent (package-dir-info))))  ; still fail
```

The latest output:

```

```

Thanks!
