27.0.50; [macOS] Problem with process input with process-connection-type nil |
|

I was investigating why eudc-ldap hangs, and stripped the problem to the
following (did this in emacs -Q):
(let ((buf (get-buffer-create "my-process-buf")))
(with-current-buffer buf
(erase-buffer)
(let* ((process-connection-type nil)
(proc (start-process "my-process" buf "/usr/bin/read" "-p" "enter
something:")))
(while (null (progn
(goto-char (point-min))
(re-search-forward "enter something:" (point-max) t)))
(accept-process-output proc 1)
(message "proc status: %s" (process-status proc)))
(message "found prompt")
(message "proc status: %s" (process-status proc))
(process-send-string proc "asdf")
(process-send-string proc "\n")
(while (not (memq (process-status proc) '(exit signal)))
(sit-for 0.1))
(message "exited"))))
If I let-bind process-connection-type to t (use pty) in above code, then
it works normally:
*Messages* :
proc status: run
found prompt
proc status: run
exited
"exited"
Buffer "my-process-buf":
enter something:
Process my-process<2> finished
But if I let-bind process-connection-type to nil (so does ldap.el), then
it hangs, and after a few seconds wait and C-g, *Messages* has only
this: "proc status: run [6 times]", and buffer my-process-buf is empty.
This is emacs master built with ./configure CC=/usr/bin/gcc --without-x
--without-sound --with-ns --with-file-notification=no --with-gnutls
--with-json --with-modules --with-threads --with-xml2 && make
Also tried --without-threads - same behavior.
Thanks.

Ok, I pushed the unconditional setting on master and am closing this
bug.
Thanks.
