Hello,
recently I've switched over to the emacs-26 branch due to some unpatched
bugs in the stable 25.3 release available on brew/cask.
I currently use the ivy package as a completion front-end for files/buffers/...
and have noticed what appears to be a bug with the `read-file-name-internal`
compiled function that it uses for its completing-read functionality.
Symbolic links now appear as directories, complete with trailing '/' and
directory-style highlighting.
Upon opening any of them I am presented with an empty buffer. With
auto-revert-mode active, this buffer attempts to continuously
revert, without any luck.
I have been unable to reproduce this bug on my Arch Linux system on both
emacs 25.3.2 and emacs 26.0.90, and it does not present itself on emacs
25.3.2 on macOS High Sierra (10.13) either.
In fact, from what I can tell, this issue seems to be entirely
restricted to version 26 of GNU Emacs on macOS (I can not speak for
any versions older than High Sierra, as this is my first
experience with a mac, and I updated before finding out about this
issue).
All symlinks that I have tested were created with the GNU coreutils
version of the `ln` program.
My emacs exec-path is also set to follow my shell path, where all GNU
coreutils take precedence over the built-in utils that macOS provides.
Following the steps to reproduce the bug does not require this however, so it
should bear no significance.
Steps to reproduce in emacs 26, on macOS High Sierra (version 10.13):
1. Setup a symbolic link in the following way:
cd ~
mkdir temp
touch temp/foo
ln -s ~/temp/foo ~/temp/bar
2. Open emacs 26 with `emacs -Q`
3. Evaluate the following elisp snippet
(let ((default-directory "~/temp"))
(all-completions "" 'read-file-name-internal))
The (incorrect) output should read ("bar/" "foo" "../" "./")
The correct, expected output is ("bar" "foo" "../" "./")
Note: this is my very first bug report, so if I left out any important
information that may be of help in fixing this issue, please let me know.
