Hi,

Did you get anything printed on the screen after entering your password?. After entering your password it will try to log you into your pop server and should give you some output at that point.

Unfortunately I don't have ready access to a POP server these days. I'll look at setting one up here to test with.

In the meantime if you could reproduce your issue, then from another terminal attach to the popx process with strace (strace -p pidof popx). That may produce a lot of output. Let if run a couple of seconds then terminate strace Ctrl-C (and popx) and paste a few of the repeating lines here, that would be helpful.

Cheers, Andrew

Done some simple testing against dovecot to at least make sure it's not just simply bit rotted.

$ ./popx -h localhost -u poptest Password: +OK Dovecot ready. +OK Logged in. 1: Test 1 Andrew Clayton andrew@... Mon, 23 Jan 2017 19:08:02 +0000 2: Test 2 Andrew Clayton andrew@... Mon, 23 Jan 2017 19:08:02 +0000 ... popx localhost> quit popx localhost> +OK Logging out. popx localhost> Connection closed by foreign host

That's the kind of thing you should see.

when i run popx, this is all print.

and my cpu start 100%.

I debug popx find the problem is here get_message_list() read_pop_response_sync(sockfd, buf, BUF_SIZE);

Thanks for the info. I've managed to reproduce the problem here.

If you change #define BUF_SIZE to be 32768, that'll probably get you going. But it's not a real fix...

[evilxyz]

I changed BUF_SIZE to 32768, and cpu is ok, but same print

I've pushed up a proper fix (fbaa43b3 Re-work read_pop_response_sync()) for the 100% problem.

However that may still not fully fix your issue as it's possible your pop server isn't giving the responses I'm expecting (I'm expecting multi-line responses to end in CRLF.CRLF).

Still, let me know how you get on with the latest version.

Cheers, Andrew

It could of course just be slow in downloading the message headers. I noticed while testing against qpopper that qpopper took much longer to send the headers and so popx looked like it had hung.

I've added a message header download progress so you can at least tell if it's doing anything.

[evilxyz]

It really works !!! thanks a lot !!!
