Command Popup Hangs Emacsclient During Startup |
|

Tue, 5 Nov 2019 10:31:10 +0100 |
Hello,
I've run into a slightly annoying issue with the emacsclient hanging
during startup due to it being unable to display a command prompt. To
recreate the behavior:
1. create a file with the contents (e.g., init.el):
,----
(defun my-hang-client ()
"This is a test function."
(condition-case nil
(let* ((choices (list
"This function seems to hang Emacsclient."))
(result (completing-read "This is a hang test:" choices nil t))
(index (cl-position choices :test 'equal))))
('quit)))
(add-hook 'c-mode-hook #'my-hang-client)
(add-hook 'c++-mode-hook #'my-hang-client)
`----
1. Start a new Emacs server: `emacs --load init.el -Q --daemon=hangtest'
2. Open a new C/C++ file from the terminal (doesn't need to exist):
`emacsclient -nc -s hangtest main.cpp'
Truth be told I'm not sure if this is the intended behavior or not, but
I personally find it a bit annoying to have the client hang on me when
I'm not opening the files in the right way. Interestingly, cancelling the
command with C-c and executing it again opens the window normally,
but without issuing the command prompt.
(Also, If it is actually intended behavior, is there an idiomatic way to
rewrite the hook such that it will still be called during startup, but
prevent the hanging?)

Thanks for testing, I'm therefore closing this bug report.
