Hi folks,
I'm having an issue with the tcp-connect function. When it fails to
connect, it seems not to clean up properly, so that I end up with lots
of open ports.
Try this code:
(require-extension tcp)
(define (error-info e)
((condition-property-accessor 'exn 'message) e))
(define (test-tcp-connect)
(condition-case
(tcp-connect "localhost" 8000)
(e (exn i/o net) (print (error-info e)))))
assuming there is nothing on port 8000. Then,
(let loop ((i 0)) (when (< i 2000) (test-tcp-connect) (loop (+ i 1))))
I get,
can not create socket - Connection refused
can not create socket - Connection refused
...
can not create socket - Too many open files
can not create socket - Too many open files
...
I'm using Version 2.731 - linux-unix-gnu-x86. Is this a bug, or is
there some way for me to release these ports when I handle the exception?
Thanks!
Matt
