[racket] tcp-read handlers
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Is there a way to install a handler for the tcp-error exception?
I have a function like this
(define (get-page link-url (max-tries 5))
(let loop ([current-try 0])
(with-handlers ([exn?
(? (e)
(if (> current-try max-tries)
(error 'get-page
"failed because it exceeded ~a tries"
max-tries)
(begin (sleep 2)
(loop (add1 current-try)))))])
(get-pure-port link-url))))
that I'm using to crawl some data, but sometimes it's printing:
tcp-read: error reading
system error: Connection reset by peer; errno=104
context...:
/usr/racket/collects/net/url.rkt:392:3
Thanks for the attention.
